Abstract

PURPOSE:To remove a complicated procedure to discriminate whether a memory cassette is connected or not, by accommodating non-volatile memories in the same form of cassette, and automatically switching a reading or writing means in accordance with the kinds of the non-volatile memories. CONSTITUTION:The non-volatile memory 3 is attachable/detachable to/from an editing station 1 and a digital picture processing part 2. The editing station 1 prepares a program to execute a series of processing, e.g., an original is read out by a reader 21 and picture parts are taken out by a picture editing circuit 24 while moving the pickup position and then printed out on a printer 23, and the prepared program is stored in the non-volatile memory 3. After writing the program, the non-volatile memory 3 is taken out from the editing station 1, and when necessary, connected to the digital picture processing part 2 to execute the written program.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a storage medium storage device. As a storage medium, magnetic bubble memory, ICPROM, and other types of non-volatile memory are stored in the same cassette, and the non-volatile memory (11iK) automatically reads and writes data.
By changing the memory, data can be written or read.

Conventionally, memory has been made into a cassette, which is removably attached to a device to be used, and memory expansion has been carried out in so-called personal computers. However, such memory cassettes do not support specific memory, e.g. IK byte mask RO) [, some static RAM combined 9/
It was limited to 4K bytes of specific format RAM, etc. Therefore, since the connected memory o+ggvt is limited, it is possible to know whether such a memory cassette is connected by directly reading or writing the contents of the message. 9 has the disadvantage that it becomes complicated. Furthermore, as the number of types of non-volatile memory increases, when they are stored in the same cassette and used for transmitting programs and data, there is a drawback that connections cannot be determined by directly reading or writing to the non-volatile memory. Therefore, it is troublesome that the type of nonvolatile memory must be determined in advance by the connected device, the reading or writing means must be changed according to the type, and then the above procedure must be followed.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, it is an object of the present invention to eliminate the need for rounding and tangential procedures for determining whether or not a memory cassette is connected when using multiple types of non-volatile memory. Media storage is meant to provide value for money.

In the present invention, when storing several types of non-volatile memory in the same cassette and using it, the cassette has nine non-volatile memos.
By storing the information regarding O@mK and the information regarding the connection, it is possible to automatically store and read/write cassettes.

The present invention will be explained below using the drawings.

The first wA shows a system configuration to which the present invention can be applied, where l is an editing stage unit, ko is a digital image processing unit,
J is a non-volatile memory. The program created at the editing stage is written into the non-volatile memory 3. A non-volatile memory J is connected to the digital image section ms2, a written program is read by the digital image processing section, and a program program is selected and executed.

The image editing circuit 3 includes an image editing circuit 3 and an operation circuit B. Here, the printer n is, for example, a laser beam printer.

The non-volatile memory J is removably attachable to the editing station l and the digital image processing section. For example, a program that performs a series of processes such as reading a document with the reader 1, extracting a portion of the image with the image editing circuit 3, moving the position, and printing it out on the printer N is created at the editing station L, and is non-volatile. Write to memory 3. After writing the program, the volatile memory J is removed from the editing stage I, connected to the digital image processing section 2 as required, and the written program is executed. In this case, there may be a plurality of programs, and the programs may be selected and executed by the digital image processing unit.

In this way, since one operating program is edited at the editing station K, management becomes easier when there are a large number of programs.

As non-volatile memory 3, magnetic bubble memory, electric erasure P
The use of solid-state memory such as IIOM has the advantage that the reliability of the device is improved. In addition to the above programs, the non-volatile memory 3 may also be used to store information such as the number of prints and billing information for each user. In that case, price management becomes easier.

By replacing the function of conventional electrostatic copying machines in which the machine does not operate unless a key counter is inserted into the machine by replacing the key counter with a non-volatile memory 3, it is possible to manage the use of the machine. It is possible. Users who have used electrostatic copying machines can accept such a replacement without hesitation since there is no significant difference in function or shape.

Conventionally, digital image data and the above-mentioned program were stored in the same hard magnetic disk unit, which made management of the nine data stored on the hard magnetic disk complicated. 1st
By configuring the system as shown in the figure, such drawbacks can be eliminated. First, because the equipment is divided by function, the functions and configuration of each machine can be simplified, which improves system reliability and makes system service and management easier. .

I) Go to 1.

The I/Oto4 is connected to the display@//, keyboard, operating circuit such as a magnetic tablet, and a printer/jK that outputs the program list.These are connected to the RO.
M10/K is stored and performs various operations using nine execution programs.

System controller 1 includes CPU Joo, R
These are OM code 0/, RAM code 02, timer code 7, interrupt controller code 0, l10-〇j, non-volatile memory controller code 04, and non-volatile memory I/F code 07. ROMJO/ reads nine programs written in the non-volatile memory 3, and the reader 1. 11il road n, printer n.

An execution program for operating the image-collecting circuit X according to the contents of the program is stored, and the program is written into the volatile memory 3 according to the signal from the operation circuit B to execute the program.

FIG. 3 shows the nonvolatile memory 3, the nonvolatile memory I/Ftoy, and JO? Shows the signal connection with. The data signal 8D is a signal for transmitting and receiving data to be written to or read from the nonvolatile memory element, and the data signal 8D is a signal for transmitting and receiving data to be written to or read from the nonvolatile memory element.
The number of signal lines used varies, one by one. The memory 1 amount determination signal SK determines whether or not the nonvolatile memo 97 is connected, and if it is connected, the 1c amount determination signal SK
ROM, magnetic bubble memory type O non-volatile memory element W
This is a signal for identifying information such as + mold and read 9 only.

The memory write inhibit signal S is a signal used by the user to specify whether programs or data can be changed or erased in the writable non-volatile memory, and can be selected using a remote switch external to the non-volatile memory J. ing.

The control signal 8o is a signal for controlling the nonvolatile memory element when writing and reading data into the nonvolatile memory 3.

The details of Figure 3 are shown in Figure 3. Therefore, 300 is a non-volatile memory element.JO is a jumper wire used to determine the type of memory. ! Oj
is a memory write signal switch that can be set arbitrarily by the user. Non-volatile memory I/F 101 and J

From this K, when the nonvolatile memory J is not connected to the nonvolatile memory 91/1101 and 267K, the memory type discrimination signal SK and the memory write inhibit signal S are all high level signals. Sometimes it becomes writable. J/ has nine connectors to which signal lines for the data signal 8, memory type identification signal S, memory write inhibit signal 8, control signal 8°, power supply, etc. are wired. FIG. 4 shows a good state when the non-volatile memory 3 is connected to the non-volatile memory I/F 101 and the co-o7. In ζ, n is an indicator indicating that the nonvolatile memory J is in a writable state, and when this is lit, writing is disabled. Reference numeral 33 is an indicator indicating the read/write status of the nonvolatile memory J. For example, the indicator g uses a two-color LED, and the user can know when the green light is on to indicate the reading or status, when the red light is on, it is in the writing state, and when the light is off, it is in the inactive state. .

In the example shown in the figure, the memory type discrimination signal S.

Since it is a reference line type, including the case where non-volatile memory J is connected and it is dangerous! 611- can be determined. By doing this, it is possible to store many memo elements, such as an electrician FROM (EIFROM).
.

Magnetic bubble memory, mask, disk ROM, etc. can be used depending on the purpose. For example, a highly versatile program that is used in large quantities is a mask ROM.
, an individual program for each user can be used as a ΣICPROM, and a large capacity program can be used like a magnetic bubble memory. Further, by providing dedicated hardware in the nonvolatile memory I/F 101 and the controller 07 to support 30 types of nonvolatile memory, further versatility can be achieved. In this case, the nonvolatile memory controller 10? The hardware of the nonvolatile memory/F10r and the code 07 may be switched and used depending on the type IIK of the nonvolatile memory element.

Before, memory 5a11 separate number sK, llIcPROM
, magnetic bubbles, mask ROMs, etc., instead of being used only to determine the type of memory element, it may be originally rewritable but prohibited from being rewritten (regardless of the memory write signal).
Alternatively, it may be used to determine whether a special program for service or factory check is installed. Table 1 shows a specific example of signal assignment for memory type discrimination *4iyS.

1. Table I The structure of the nonvolatile memory element 300 will be described. Below is the non-volatile memory J for programs and billing data.
The data stored in a file is called a file. 10. As a reward, an example of a memory configuration of a non-volatile memory element is shown. , 2nd Reward memory can be broadly divided into two parts. It is divided into an index part that stores information such as the name of the file and the physical prior application address of the data part of the file, and a file data part that stores the actual program and data part of the file. The index part is from non-volatile memory 1.
It is stored starting from a specific address such as the first application address, and is used for file management.

Specifically, the file name, file size indicating the size of the file data portion such as 100 bytes or 10 blocks, program, file type indicating billing data 01111I, write protection indicating whether the individual file is rewritable, It is composed of file data start addresses indicating the physical destination address of the file data portion of an individual file.

FIG. 7 shows 1 the procedure for reading a refile from the nonvolatile memory J. First, when reading a file in the non-volatile memory J, in step 5P10, the above-mentioned message type identification signal S is determined, and the non-volatile memory J is connected (in this embodiment, the memory type identification signal S) is determined. If the signal 8.0 value is other than /S), it is determined whether the signal is set. If it is not connected, an error flag is turned on in step SP/≦, and the program that requested to read the file is notified of the read error. Next, step! P
At //, it is determined based on the memory type determination signal Smm whether or not the nonvolatile memory 7101 and 07 have a hardware I/F for reading Sunagawa. If it is not possible to perform the transfer, the process moves to step 5pz46c. State SP
/Co is compatible with non-volatile memory elements and has nine hardware! 71, nonvolatile memory I/F 101 and co0
7. Switching is performed internally. At step Sr/J, the index portion of the non-volatile memory element is read, and at step SP/
Use # to determine whether the required file exists. If the necessary file does not exist, the process advances to step SP#. In step s p is, the file data and the prior application address of the index portion of the corresponding file in the nonvolatile memory device are read, and at the same time, the file size is used to read the file data portion. At the same time, the error flag is turned off to indicate that the reading has been completed normally.

By the above steps, extract the contents of the file in the non-volatile memory.
Automatic reading becomes possible regardless of the number 7 W*.

- Figure 1 shows the procedure for writing a file to the non-volatile memo 3. If there are nine file write requests, step 8P.
In step BP10, the same process as step BP10 is performed. If this volatile memory 3 is not connected, step 8PJ/
Go to K and turn on the error flag. Step B1
'J/, by write protect switch X and JO3,
It is determined whether the memory is a read/write-only nonvolatile memory that does not accept a memory write inhibit signal by the memory type/value determination code S.

The purpose of read/write-only nonvolatile memory is to store files that need to be constantly updated, such as billing for needs, the number of prints, etc., and to prevent file updates from being inhibited by memo write signals. With the goal. Step 5P2 in case of read/write only non-volatile memory
Proceed to step 3. In step Sr here, check whether the write protect switch is on or the memory type determination signal 8K
From K, it is determined whether file writing is physically impossible, such as in a mask ROM. If writing is not possible, proceed to step S P J/O. In step 8P 3, do the same as step Sr//.

It is determined whether there is a hardware I/F corresponding to the non-volatile memory element, and if there is, a negative step S P JIK advance circuit is switched. If there is none, proceed to step 8PJ/. In step 8P, the index portion of the non-volatile memory element is read, and it is determined in step 8P whether or not the same file exists. If there are nine identical files,
The write F protect of the file index portion is read to determine whether the file is rewritable, and if it is not rewritable, the process proceeds to step 8PJ/.

In step 8P, the size of each file in the non-volatile memory 3 is read and it is determined whether the size of each file in the non-volatile memory 3 will not exceed the capacity of the non-volatile memory 3 due to new file writing or updating. If the capacity is insufficient, step SPJ/
Proceed to. In step 5P30, an index portion and a file data portion are written in accordance with the file to be written.

FIG. 9 shows an example of one program registration. Note that the program here refers to a program executed by the digital image processing section. Specifically, one of the nine programs stored in the non-volatile memory 3 is selected (according to the operation instruction from the operation circuit B), the contents of the program are read out and executed sequentially, and the reader 19 communication circuit , printer n1 image editing circuit 3 is operated according to a series of stored operating procedures. In this example, editing and registration of programs are performed at editing station 1, so the procedure shown in FIG. 1 is performed at editing station 1.

Edit the operating circuit/2 and save it to the non-volatile memory 3.
When you enter the command to register, first step 8P
Enter information such as the name and number of the program to be registered in 〇. Non-volatile memo) Read whether the same program (file) exists in JJ at step 8P#/. If reading is not performed normally in step 8P, an error is displayed in step 8P, and the program registration is ended.

In step 8P-3, it is determined whether or not the same program exists, and if there is, the process advances to step 8P-11 to display whether the program may be updated. Then step sp
uj waits for operation input. @Y in Step 8P
If there is a key force for ES ''', step 81
Proceed to step 17, and if @No'', program registration is ended.

In step BP#7, the program is written to the non-volatile memory 3, and it is checked whether the writing is completed normally or not.
Determine by ut.

The program written in the non-volatile memory J in this manner is connected to the DigiMole image processing section and is reduced in depth by the operation input of the program depth from the operation circuit. Next, the program depth procedure in the DigiMole image processing section will be explained using FIG.

First, name 2 of the program to be executed in step 8Pj6.
Enter information such as number. In step 8Pj/, it is determined whether the input program is the basic program stored in iIXROMJO/. This basic program is the same as the non-volatile memory 3 in terms of content, but it is prepared so that it can be operated relatively easily and in depth even without the non-volatile memory 3. For example, the program is such that the reader 1 or the printer n copies the document directly like a conventional electrostatic close-up device.

If the program in the nonvolatile memory J is selected, the process advances to step 81PjJ and the program (file) is read. In step 8PjJ, it is determined whether the program has been read normally, and if there is an error, step 5
Proceeds to PjjK, displays an error, and stops program execution. If the program is read normally, the program proceeds to step 8Pj and the read program is executed.

If the basic program is selected, step 5 ps
Proceeding from step BPIj to step BPIj, memory type determination signal 8
．． is used to determine whether nonvolatile memory 3 is connected. If connected, step 8Pj
Proceed to step 2. If the non-volatile memory J is not connected to the digital image processing unit, step s p ss is combined with the next step 8Pj≦ to prevent the basic program from being executed, that is, to prevent the digital image processing unit from operating. This is a procedure for Step SPj Bude 4
, a procedure for determining whether a basic program can be executed when the non-volatile memory J is not unified. Specify. If the program is not executable, the basic program is not executed and the process proceeds to steps 5pjr6c. In step 8P74,
By making it possible to select whether or not to run the basic program when the non-volatile memory 3 is not connected, it is possible to widen the range of ways to manage the DigiMole image processing section.
It has the characteristic that it becomes the first Yosho user.
