Description

DETAILED DESCRIPTION OF THE INVENTION Conventionally, 70-bit discs, which can be attached to and removed from devices in the form of program and data storage cassettes, are used to transmit information.
This is done using magnetic tape, etc. However, these information transmission systems have the drawback of poor reliability because they have mechanically moving parts. Magnetism/(
However, non-volatile solid-state memory tags such as Pull Memo 1 are being used to convey this information.

In addition to magnetic puzzles, non-volatile storage media used for such information transmission include, for example, liver dentures and non-rewritable masks RO.
Magnetic I < pull memory has high information storage secrecy and can store large amounts of information
Erasable, electrically erasable and randomly accessible IPRO
M is an O mask R that is characterized by short access time.
OM Fi has the 4I characteristic of being cheaper when producing large quantities of the same program as cassettes, such as toy programs. Characteristics of Nire et al.If we limit non-volatile memory to one type of device that uses it,
The characteristics of each non-volatile memory cannot be utilized. Therefore, it is desirable to have a non-volatile memo Vt built-in in a cassette of the same type so that different types of non-volatile memory can be used depending on the purpose. In view of this, it is an object of the present invention to provide an information transmission device using a cassette, which can freely use a plurality of types of nonvolatile memories.

The present invention will be described in detail below with reference to the drawings. FIG. 7 shows the configuration of an optical system to which the present invention is applied, where / is an editing station, C is a digital image processing section, and 3 is a nonvolatile memory. A non-volatile memory J is connected to a digital image processing unit 3 which writes a program created by an editing station/ into a non-volatile memory 3, and the written program is read by a digital image processing unit S-1 and the program is selected and executed.

Editing station/kura, summary collection *ios Consists of a display// used when creating a program, an operating circuit/J, and a printer/J. In addition, the digital image processing section-2 is controlled by the system controller O and the system controller 20 to exchange digital iii* data between the reader core 1 which performs digital uJlk reading and other digital image processing sections. The communication circuit w1, the printer 3 that records the digital image g1, the image 9 editing circuit that performs processes such as partial extraction, transfer, and storage of the digital image, and the operation circuit!・Here, the printer 2j is, for example, a laser beam printer. ◎ The printer 2j is removable from the non-volatile memory, the editing station 1, and the digital image processing unit. A program is created at the editing station L that performs a series of processes such as performing partial dispersion and t of Goken in the Rin editing circuit λ, moving its position, and printing it out to the printer 23, and writes it to the nonvolatile memory J.・
After writing the program, remove the non-volatile memo from the IJ J Yr editing station/digital III if necessary.
*Processing unit-2 [Connect and execute the written program. In this case, there may be a plurality of programs, and they may be selected and executed on the digital-1 image processing section λ side.

In this way, by separating the operating program from the editing station/digital image processing unit, management becomes easier when there are a large number of programs.
In addition to the above 10 grams, non-volatile memory J is used to store information such as the number of prints and billing information for each user. In that case, the management of the device becomes easier.

By replacing the counter 9 with the non-volatile memory 3, the function of the conventional Seiden photocopying device is that the machine cannot operate unless the key e counter is inserted into the device.
Those who have used an electrostatic multi-zero device that can manage device usage can accept it without hesitation since there is no major difference in function or shape.Conventional, digital The image data and the above 10 gram storage were stored on the hard magnetic disk, but the management of the data stored on the hard magnetic disk was complicated.By configuring the system as shown in Figure 1, , such shortcomings could be eliminated @also due to dividing the device by function.

In this example, program editing and registration are performed at the editing station, so the procedure shown in Figure 1 is performed at the editing station. When inputting the code to register the program edited with the O operation circuit l into the non-volatile memory 3, the O non-volatile memo I) is entered where information such as the name and number of the program to be registered is entered in step speo.

Determine whether the input program ID is the basic program stored in the ROM CO/.◇This basic program is the same as non-volatile memory 3 in terms of content, but even if non-volatile memory J is not present, For example, a reader/printer is a program that is prepared to perform relatively simple operations. If a certain program in the non-volatile memory 3 is selected, the process proceeds to step 8Pr and the program (file) is received. In step SPjJ, it is determined whether the program has been read normally, and if there is an error, the process proceeds to step 13PjtlK, an error display is performed, and the program execution is stopped. ◎If the program has been read normally, step 1
