Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a film cartridge capable of recording index information necessary for searching microfilm and the like.

[Conventional technology]

Microfilm was wound and stored inside a cartridge, and its index information was displayed in letters on a piece of paper attached to the outside of the cartridge. However, the index information recorded in this manner can only be recognized by humans, and it is impossible to automatically search these film cartridges. On the other hand, recently some film cartridges have index information displayed on the outside of the film cartridge as a bar code. Such film cartridges can be automatically searched by a machine, and a microfilm file system that is systemically connected to an electronic file system reads the contents of the microfilm cartridge with the electronic file system, edits this information, and stores it in memory. It can be used for a long time. However, if you also need to change or add index information to a cartridge,
The barcode index information has the disadvantage that information cannot be changed or added.

On the other hand, in memory cards (used in cash cards, credit cards, etc.) that are currently frequently used, information such as a code number is written on a magnetic tape attached to a plastic card. However, recently there has been an increasing need to write information on cards, but it is difficult to write information on cards that use magnetic tape, such as those mentioned above, with terminal equipment, and there are only a few writable information devices. The disadvantage is that there are few.

[Problem that the invention seeks to solve]

The present invention aims to eliminate the drawbacks of the conventional film cartridge I-ridge mentioned above and to provide a film 18 cartridge from which index information can be read and written.

[Means for solving problems]

In order to solve these problems, the microfilm cartridge of the present invention includes a solid-state memory in which index information is recorded and an external connection part that electrically connects the solid-state memory to the outside.

[For production]

With this configuration, when the film cartridge is set in the film search device, information can be input/output from the solid-state memory in which index information is recorded through the external connection section.

〔Example〕

FIG. 1 shows an embodiment of a film cartridge to which the present invention is applied. A film F is wound and stored in the film cartridge 1. A solid-state memory card (IC card) 2, such as a semiconductor memory or a magnetic bubble memory, which can be read and written, is attached to the side surface of the film cartridge 1.

The IC card 2 has an external connection terminal 3 that is electrically connected to the outside.
It is equipped with The film cartridge 1 and the IC card 2 may be integrally molded, or the IC card 2 as shown in FIG. 2 may be detachably attached to the film cartridge l.

When the microfilm cartridge l to which the IC card 12 is attached is loaded into the information search machine, the connection terminal of the IC card 2 and the connection terminal of the information search machine (not shown) are electrically connected.

FIG. 3 shows a signal processing block circuit for importing the memory contents of the IC card 2 into the information search device.

Through the connection terminal 3 of the IC card 2, the input/output interface 5 is connected to an erasing/writing circuit 7, a reading circuit 8, and a control circuit 9 by a changeover switch 6 of the information search machine.

When the information retrieval machine is in the information retrieval state, the IC card 2 is connected to the readout circuit 8 side through the input/output interface 5 and the switching switch.
Read index information from the memory of the C card 2.

When erasing or writing index information on the IC card 2, the selector switch 6 is switched to the erasing/writing circuit 7 side and the erasing or writing operation is performed.

In this way, index information is read out from the IC card 2 immediately after the film cartridge 1 is inserted into the information retrieval device. If you want to correct or erase the index information while looking at the film frame whose information has been searched, issue a correction/erase command from the control circuit 9, turn the selector switch 6 to erase, and switch to the write circuit 6 to erase and write the memory of the IC card 2. can do.

In addition to the above-mentioned inversion, the IC card memory can also be used as a non-volatile memory if a dedicated device capable of writing and erasing data based on signals from the RAM in the information retrieval device is provided.

Although the IC card is designed to be removable from the film cartridge, it is also possible to directly embed or incorporate it into the film cartridge.

Further, the external connection terminals 3 of the IC card 2 are covered with a slidable protective cover 10 as shown in FIG. may be exposed and electrically connected to the connection terminal of the search device. In this way, the connection terminals will not be contaminated.

〔effect〕

As explained above, in the film cartridge I-Ridge of the present invention, if the index information is recorded on the IC card, the index information of a large number of film cartridges can be stored in the microprocessor without providing a new search memory means. It becomes possible to read out the film cartridge while stored in the film cartridge management shelf and search for a desired film cartridge. Even if the number of cartridges increases, they can be easily managed and searched.

Additionally, index information can be created, added, and changed accurately and easily. Especially when an electronic file is connected to a microfilm search machine, changes and additions to information in the electronic file are made using the microfilm cartridge's IC card, which is very convenient since the information remains the same even when used with another search machine. It is.
