A system for first justifying a text line according to a system minimum escapement unit, and then rejustifying the line according to a minimum escapement unit for a printer which is to be utilized in printing the line. The first justification of the line is in a normal manner. That is, any residue is divided by the number of word spaces on the line to obtain a quotient and any remainder. The extent of word space expansion is then the value of the quotient plus the remainder until exhausted. Rejustification for the printer being utilized is accomplished by dividing each system justified word space size by the printer minimum escapement unit to obtain a new quotient and remainder. Each system justified word space is then converted to a value including the obtained quotient for each space, and the remainders for all spaces are accumulated for adding to the first word space.
A channel selection circuit selects signals of a desired frequency from television signals. A channel interpretation circuit determines whether or not the signals thus selected are low-band or high-band. When the signals are low-band, a movable contact is coupled to a D.C. power source. When the signals are high-band, the movable contact is coupled to the ground. A first trap circuit traps the intermediate-frequency components of the selected signals. A second trap circuit connected to the first trap circuit, and a third trap circuit coupled between the output of the second trap circuit and the group and also connected to the movable contact of a switch section, cooperate, thereby trapping predetermined signals. More specifically, when the movable contact is coupled to the D.C. power source, a semiconductor switching device is turned on, thus causing the second and third trap circuits to trap high-band signals and intermediate-frequency signals. When the movable contact is coupled to the ground, the switching device is turned off, thereby causing to the second and third trap circuits to perform the image-trapping of high-band signals and to trap low-band signals.
A dot-type printer has heretofore been unable to output characters of the pitch which does not coincide with multiples of the dot-width by integers when such dot-width is either electrically or mechanically fixed, causing considerable errors and not being in compliance with the recommendation of CCITT. The system according to the present invention provides a means to obtain the distance between a character and a printing reference point and to output the character at a position which is separated from the reference point by the distance in a multiple of the dot-width by an integer and which is either immediately before or after the point of the distance thus obtained. By such output control, the character outputted can remain within the range recommended by CCITT with only negligible errors.
An intercharacter space processing apparatus for use in a printer, comprises a receiver for receiving a print signal, a memory for storing character codes received by the receiver, a dot space control unit responsive to an intercharacter dot space signal received by the receiver for inserting a prescribed dot space signal between the character codes stored in the memory, so that the printer will print characters on a print surface based on information stored in the memory, first means for producing a signal when a dot space area on the print surface according to the dot space signal inserted by the dot space control unit exceeds a dot space area represented by a space code given by the print signal, and second means responsive to the signal from the first means for converting the dot space signal into the code and storing the space code into the memory.
A musical score block copy forming apparatus has a musical keyboard (1) having a full-scale key group and a chromatic-scale key group, and a function keyboard (2) having function keys, and the like. Data input at the keyboards (1, 2) and data necessary for a musical score forming arithmetic operation are stored in a storage unit (7). The input data and the data stored in the storage unit (7) are subjected to arithmetic processing by an arithmetic processing unit (3). The arithmetic processing unit (3) has a layout change function used when a musical score is formed, and can display a musical score on a display (4) on the basis of an arithmetic result. The musical score displayed on the display is output to an output unit (5) for forming a block copy of the musical score.
The present invention relates to a text editing system with a line end line feed function and an indentation function. In particular, a line end position Pg is stored in advance in a line end position storage unit 1, a line feed code in text data are detected by a line feed code detection unit 2 at the time of a text editing process after a character is inserted in or deleted from text data written in a subsequent file 4, shifts the position of the line feed code to the line end position Pg if the position of the line feed code does not match the line end position Pg, and the end of a line in a document is set to the line end position Pg. If there is a prescribed number of blank codes at the head of a line, at the time of a text editing process after insertion or deletion, a body of text can be edited in such a way that there are prescribed blanks that are always located at the head of the line by shifting blank codes.
