BACKGROUND OF THE INVENTION
This invention relates to a cassette and cassette-rent control system, for example, utilizing the states of cassettes, such as the rent and return of cassettes, and more particularly to a rent control system for controlling the rent and return of
cassettes, each containing an article such as an information-recorded medium and an IC circuit storing the commodity information concerning the article.
In rental shops for renting video tapes and video discs to the public, a clerk records, on a notebook or a rental slip, various necessary information, such as the name or the code of a rental article, the address and the name of a customer, and
the rental date before renting articles, such as video tapes. When receiving the returned rental article, the clerk erases the rental records. Such recording work of rental information by the clerk reduces the efficiency of his rental work. Further,
mistaken operations are inherent to such recording work, since it is performed manually. For example, he or she may fail to erase the recorded information when receiving the returned rental article.
Software rental companies for renting rental articles to the public must pay to the software suppliers, such as recording, TV and motion picture companies, a royalty which is calculated depending on the number of rentings. Therefore, the rental
company must accurately control the renting work, at least the number of articles rented. Thus, if the conventional rent control is performed by manual work, it is almost impossible to accurately and quickly control the rental articles.
To cope with this, there is proposed a software rent control system. In this system, a bar code representing an article code is attached to each cassette tape. Membership cards are issued to customers, bearing the numbers assigned to them. In
renting an article to a customer, the clerk reads out the bar code of the article by a bar-code reader, and stores into a memory device the bar codes together with the the customer's number.
However, this rent control system still involves problems in the rent control work. In the rent control system, the article code of cassette, which is being rented, have been stored in the memory device. To see how many times the cassette has
been rented, it is sufficient to read and print out the contents stored in the memory. In this case, the clerk must read the bar codes of the cassettes every time they are rented or returned.
Additionally, the memory device does not contain such data indicating whether or not the unrented cassettes have been set in the shelf. Therefore, in checking inventories at the end of month or at the end of day work, the clerk must carefully
check and itemize the stocked cassettes. This work is time consuming, and the results of the work are inevitably accompanied by inexactness.
SUMMARY OF THE INVENTION
It is, therefore, an object of this invention to provide a new and improved cassette and rent control system thereof, which can exactly and easily control the rent and return of cassettes.
According to one aspect of this invention, there is provided an information recording cassette comprising cassette means accommodating an article, IC circuit means provided in the cassette means, for storing commodity information concerning the
article, and signal output means provided in the cassette means, for transferring the commodity information stored in the IC circuit means to outside.
According to another aspect of this invention, there is provided a rent control system for controlling the rent and return of cassettes. This system comprises a plurality of cassettes to be controlled, each containing an article, and being
provided with IC circuit means for storing commodity information concerning the article, and signal output means for transferring the commodity information stored in the IC circuit means to outside, a plurality of shelf means for respectively
accommodating a plurality of the cassettes to be controlled, and control means provided in connection with the plurality of shelf means, and having a plurality of signal input means for receiving signals from the signal output means of the cassettes, and
memory means being coupled with the control means so as to store signals from the plurality of signal input means.
In the cassette thus arranged, if a cassette holder shelf is provided with terminals, which are electrically connectable by signal output units to the IC circuits of the cassettes, the article data stored in the IC circuits provided in the
cassettes can be read out by an external controller. Therefore, the rent and return of cassettes can be controlled exactly and easily.
In the rent control system, the IC circuit for storing the article such as the tapes of cassettes is incorporated in the cassette. Therefore, the article information stored in the IC circuits can be read out at any time, while the cassettes are
left on the cassette holder shelf. If a cassette is pulled out from the shelf, the rental information of the pulled out cassette is automatically stored into the rental control memory. When the cassette is returned and set on the shelf, the cassette
return information is automatically stored into the rental control memory. Thus, when the cassettes are pulled out of, and put on, the shelf, the rent and return data are automatically stored into the memory device. Therefore, the easy and exact
rent/return control of cassettes is realized.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
Some specific embodiments of this invention will be described referring to the accompanying drawings.
Referring first to FIG. 2, there is illustrated a rent control system using a cassette control system, which is a first embodiment of this invention. In this embodiment, the rent control system is installed in a video rental shop for renting
video tapes, or the like, to the public. In the figure, reference numeral 21 designates a rack with a number of shelves 22 on the front. Main body controller 23 is installed adjacent to rack 21, operation panel 25 covers the front of main body
controller 23.
Each shelf 22 mounted to rack 21 includes a plurality of ledges 22a arranged on the front of rack 21, horizontally and in parallel, as shown in FIG. 3. A pair of guide grooves 22b and 22c are respectively formed on the upper and lower surfaces
of each ledge 22a. The lower guide groove 22b has stepped portion 22d for preventing the cassette from slipping off. Stepped portion 22d rises at the front of the lower guide groove 22b. In use, a cassette 24 of the video tape shown in FIG. 4 is set
between opposing guide grooves 22b and 22c, in the longitudinal direction (arrow direction). When cassette 24 is fully inserted along guide grooves 22b and 22c, the whole of cassette 24 passes stepped portion 22d and is placed in the horizontal section
of guide 22b. To pull out the cassette, the end of cassette 24 closer to stepped portion 22d is slightly raised, and pulled to your side.
FIG. 1 shows in cross sectional form cassette 24 which is left inserted into shelf 22, and placed in the prescribed position. A pair of reels 24b and 24c are disposed in cassette case 24a shaped like a parallelepiped. Tape 24d is wound around
reels 24b and 24c. Window 26 is formed in the corner enclosure 24e of cassette case 24a, through which an optical communication is allowed. In corner enclosure 24e, IC circuit 27 is disposed facing window 26. Printed circuit (PC) board 27e supporting
IC circuit 27 is attached to the inner surface of cassette case 24a. Disposed on PC board 27e are light emitting element 28a and photodetector element 28b, which constitute a signal output unit. Through holes are formed in PC board 27e at the location
thereof, facing the light emitting surface and the light receiving surface of those elements. Battery 29 is provided adjacent to PC board 27e. These electronic parts are located within the corner enclosure 24e of cassette case 24a, thus not hindering
the running of the tape.
As shown in FIG. 1, when cassette 24 is inserted into shelf 22 until it is placed at the regular position, light emitting element 47a and photodetector element 47b are provided in the upper groove 22c and face the window 26 of cassette frame 24a. Microswitch 45 is mounted on the wall 22e of the shelf 22. When cassette 24 is inserted into shelf 22 up to the prescribed position, microswitch 45 is closed.
FIG. 5 is a block diagram illustrating IC circuit 27. Central processing unit (CPU) 27a is connected by bus line 27b to read o | | |
