BACKGROUND OF THE INVENTION
This invention relates in general to an electronic display apparatus, in
particular to an electronic reminder which electrically stores information
on person's names, addresses, telephone numbers, etc., and displays the
information on request.
In recent years, many kinds of portable electronic display apparatus are
available. Electronic diaries and electronic telephone directories are
examples of such portable apparatus. An electronic diary which stores
schedules and messages, and which displays a message at the scheduled time
is disclosed in U.S. Pat. No. 3,999,050. An electronic telephone directory
which stores persons' names and telephone numbers, and which retrieves a
telephone number in accordance with the designated person's name is
disclosed in U.S. Pat. No. 4,117,542.
It often happens that a telephone call to a person results in a busy signal
or a recorded message. In such a case, the caller may think that he will
call again after a while but is likely to carelessly forget it once he has
started another task. Everybody would have such an experience. At such
time, it is convenient to use the electronic diary. In a conventional
electronic diary, however, setting an alarm time requires a plurality of
steps and/or key operations; namely, the operation is complicated.
SUMMARY OF THE INVENTION
It is therefore an object of the present invention to provide an electronic
reminder having high operability to set an alarm time.
It is another object of the invention to provide an electronic reminder
which is able to set an alarm time by only one key operation.
It is a further object of the invention to provide an electronic reminder
which displays information at the time of the alarm time setting when the
present time coincides with the alarm time.
The electronic reminder comprises first input means for inputting
information, memory means responsive to said first input means for storing
said information, displaying means responsive to said memory means for
displaying said information stored in said memory means, second inputting
means for generating an instruction signal of alarm time setting, time
keeping means for counting a present time, alarm time setting means
responsive to said second input means and said time keeping means for
setting alarm time, object information store means responsive to said
second input means for storing the information displayed at the time of
depressing said second inputting means in accordance with said instruction
signal, comparison means responsive to said time keeping means and said
alarm time setting means for comparing the present time with the alarm
time, and selective means connected with said object information store
means and responsive to said comparison means for sending the content of
said object information store means to said displaying means for
displaying same when the present time coincides with the alarm time.
These and other objects of the invention will become apparent and obvious
to those skilled in the pertinent art upon referring to the following
description provided in connection with the accompanying drawings, of
which:

DESCRIPTION OF PREFERRED EMBODIMENT
There is shown in FIG. 1 a functional structure of an electronic reminder.
The operator inputs into the electronic reminder information on person's
names, addresses, telephone numbers, etc., via input means 6 having a
plurality of keys comprising ten keys, character keys, and function keys.
The electronic reminder has three functional modes. First mode is an
information input mode for inputting the information into the reminder.
Second mode is an information search mode for retrieving and displaying
stored information and displaying them. And last mode is an delay time set
mode for setting a alarm delay time. Any mode can be selected by
depressing a mode select key. In the input mode, when a key is depressed,
input checking means 7 checks which key is depressed and operates
information input means 8 so as to store the information into memory means
9. In the search mode, when the return key is depressed after key words
have been inputted, input checking means 7 generates a memory address of
the information to be stored under the key word. The memory address is
sent to a reference address store means 12.
This invention sets as an alarm setting time the current time plus "a
particular time" by one keying-in operation. In the delay time set mode,
the particular time can be set freely by the operator and is stored in
added time store means 10 by input checking means 7.
The reminder has a shape to be held by one hand. A plurality of keys and a
display panel are arranged on a case. A key arrangement of the reminder is
illustrated by way of example in FIG. 2. The display panel 30 is in the
upper portion of a front face. The reminder has sixty two keys in this
example. The keys comprise ten numerical keys 31, forty five Japanese
character keys 32, four cursor keys 33, a return key 34, a mode select key
35 and an alarm set key 36 for setting the time which is currenttime plus
"a particular time" as the alarm time.
The information already input can be taken out and displayed on the display
panel 30 of the display means 11-1. The memory address of the displayed
information is usually stored in a reference address store means 12. The
address in the store means 12 is changeable by the key operation of the
input means 6. The memory address in the reference address store means 12
is written into an object information address store means 18 when second
input means 15 is depressed.
Time keeping means 13 serves as a clock and rewrites the content of date
and time temporary store means 14 at intervals of one second. When second
input means 15 is depressed, a time computing means 16 adds the content of
the added time store means 10 to the content of the date and time
temporary store means 14. The results of the calculation is stored in
computed result store means 17 as an alarm time.
Date and time comparison means 21 compares the present time stored in the
temporary store means 10 with the alarm time stored in the computed result
store means 17, and sends control signals to an alarm generating means
11-2 and reference information selective means 19 when the present time
coincides with the alarm time. The alarm generating means 11-2 generates
drive signals for driving a buzzer when the control signal is inputted.
The reference information selective means 19 receives the address sent
from the reference address store means 12 and the address sent from the
object information address store means 18. Usually the selective means 19
outputs the address sent from the reference address store means 12. But
the selective means 19 outputs the address sent from the object
information address store means 18, when the control signal from the
comparison means 21 is inputted. The output address of the selective means
19 is sent to display address designating means 20. The designating means
20 addresses the information in the memory means 9. The information
designated by the address is displayed by the display means 11-1 on the
display panel 30.
FIG. 3 is a block diagram of the electronic reminder which includes a read
only memory (ROM) 1 for storing a program, a random access memory (RAM) 2
for storing various information, and a central processing unit (CPU) 5 for
executing the program stored in the ROM 1, for displaying particular
information on a display 3, and for decoding the information from input
means 4.
The operation occurring when the operator works second input means 15 will
be described using one specific example.
First, assume that the operator is now reviewing to the information "Kazuo
Tanaka 03-123-4567" to make a telephone call to Mr. Tanaka. Further assume
that the operator made a telephone call to Mr. Tanaka in accordance with
the displayed number, but unfortunately she could not contact Tanaka. The
operator gave up talking now at once with Mr. Tanaka and considered that
she would make a telephone call again after a while. Thus she pressed the
alarm time setting key 36 included in the second input means 15 so as not
to forget it. When the second input means 15 is operated by the operator,
the data and time computing means 16 adds the content of added time store
means 10 to the content of data and time temporary store means 14 and
stores the result in the computed result store means 17. Also assume that
the time when the operator pressed the alarm time setting key was 3:00 PM,
October 10 and that the present time to be added was 15 minutes, the
information stored in the computed result store means 17 is then 3:15 PM,
October 10. At the same time the object information address store means 18
receives address information as to where the content of reference address
store means 12, namely "Kazuo Tanaka 03-123-4567" is stored.
Thereafter the operator may input a new person's name or telephone number
or review other information inputted already. Therefore, the content of
reference address store means 12 may at once turn into an address
different from the address stored in the object information address store
means 18.
Usually, the reference information selective means 19 selects reference
address store means 12 and delivers the address information to display
information address designating means 20.
The designated means 20 takes out information to be referred to from the
memory means 9 and the information is displayed by the display means 11-1.
The date and time comparison means 21 compares the content of date and time
temporary store means 14 with the content of computed result store means
17. In this particular embodiment, when 15 minutes have elapsed since the
alarm time setting key was pressed the contents of the two store means
coincide. At this time, the reference information selective means 19
selects as reference information the information in store means 18 and the
alarm generating means 11-2 generates an alarm signal. As a result,
display means 11-1 again displays "Kazuo Tanaka 03-123-4567" and at the
same time an alarm sound is generated.
FIGS. 4 and 5 show the above operation in a flowchart. The CPU 5 performs
at all times regular operations including inputting, referring to
information, etc. (step 1 in FIG. 4), the processing on "alarm time
setting" key (step 2), and the processing of the timekeeping result (steps
3, 4, and 5). The processing on the "alarm time setting" key is as shown
in FIG. 5.
First, it is checked whether or not the "alarm setting" key is pressed. If
so (step 6 in FIG. 5), the content of registers A and B are added and the
result is stored in register C (step 9 in FIG. 5). At present, register A
contains time information, and (step 7 in FIG. 5) register B contains a
time to be added (step 8 in FIG.5).
An address indicating the place where the information referred to at this
time is stored is in register D (step 10 in FIG. 5).
At step 3 in FIG.4 the timekeeping result is monitored at all times and it
is commanded that the content of register A is compared to the content of
register C once per minute (step 4 in FIG. 4). As a result of the
comparison at step 4 in FIG. 4, when the content of register A coincides
with that of register C, namely, when the current time has reached the
alarm setting time, an alarm sound is generated and the storage
information designated by the content of register D is displayed (step 5
in FIG. 4). Thereafter the regular operation is resumed.
According to this embodiment, an alarm time setting operation is very much
simplified. Namely, one operation can set an alarm time to a predetermined
time after the current time. The operability of reminder is improved as
well as keying errors due to complex key operation is completely
eliminated, so that an electronic reminder very excellent in operability
and reliability is provided. It is to be understood that while the present
invention has been shown and described with respect to a preferred
embodiment thereof, the scope of the invention is not intended to be so
limited and other equally suitable and equivalent modifications and
changes may be made therein without departing from the spirit and scope of
the invention.
