JPH02304623A - Display method at changing time of soft version - Google Patents

Abstract

PURPOSE:To simplify a change work, and also, to prevent the generation of an operation miss by writing a soft version number stored in a ROM in a RAM, and displaying the change operation contents, when the corresponding numbers of both of them do not coincide with each other at the time of starting. CONSTITUTION:This method is constituted so that the soft version number of a control program stored in the ROM 26 is written in the RAM 25 in advance, and at the time of starting the system, the soft version number of the RAM 25 and the soft version number of the ROM 26 are read out, these two pieces of soft version numbers are compared, and in the case of discordance, it is decided that the soft version number is changed and the date replacement of the RAM 25 is executed, and thereafter, matters that demand special attention and the operation contents attending with the change of the soft version are displayed successively on an indicator 17 in accordance with the operation procedure. By inputting the data in accordance with the display by this constitution, the work for changing the soft version can be completed easily, and also, there is no possibility that an operation miss is generated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display method that sequentially displays operating procedures associated with software version changes.

[Conventional technology]

Various devices such as photo printers have a built-in microcomputer, which sequentially controls each part according to a control program written in a ROM. Control program versions are often changed to improve operability or add new functions. When this version change is performed, the ROM that stores the old software version control program is removed from the device, and the ROM that stores the new software version control program is attached to the device.

In general, when changing the soft virginity, in addition to replacing the ROM, human labor is required to re-enter data due to differences in RAM addresses and to generate data (numeric data, condition instruction data, etc.) to perform new functions. It is said that Precautions and operating procedures for such data input are described in the version change manual, so conventionally, users read this while inputting data.

[Problem to be solved by the invention]

When changing software versions, it is necessary to read the manual while performing the work, which may lead to operational errors.Additionally, changing the RAM address requires re-entering data, making the operation cumbersome. Ta.

SUMMARY OF THE INVENTION An object of the present invention is to provide a display method when changing a software version that eliminates the need to re-enter data when changing a software version and eliminates operational errors.

[Means to solve the problem]

In order to achieve the above object, the present invention writes the software version number of the control program stored in the ROM to the RAM, and when the system is started, the software version number of the control program stored in the ROM is written in the RAM.
The software version number written in the RO
Read the soft virgin number of M and compare these two software version numbers. If they do not match, replace the data in the RAM, and then write the precautions and operation details associated with changing the software version into the operating procedure. Therefore, the information is displayed sequentially on the display.

[Effect]

When the system is started, the version numbers are read from the ROM and RAM, and if they do not match, it is determined that the software version has been changed, and this change is displayed on the display. After this display, data in the RAM is replaced, and then precautions and operation details are displayed in the order of operation. Then, by inputting data according to the instructions on the display, the work of changing the software version is completed.

〔Example〕

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 3 showing the printer processor, the printer processor 10 is composed of a printer section 11 that prints and exposes a negative image on color paper, and a processor section 12 that photographs and develops the exposed color paper. At the top of the printer section 11, a film carrier 1-4 holding a negative film 13 and a lamp house 15 for illuminating the negative film 13 are provided. The printer section 11 also includes a keyboard 16 for inputting data and instructions, a display 17 for displaying operation details and input data, and a negative monitor for observing the frames of the negative film set at the print position. A window 18 is provided.

As shown in FIG. 2, the printer section 11. Processor part12. Keyboard 16 is connected to I10 boat 20. In addition, this I10 baud) 20 has a display 1
A driver 21 for driving 7 is connected. I
/p port 20 is connected to CPU 23 via path line 22.
It is connected to the. In addition, the pass line 22 includes a RAM
25 and ROM26 are connected. This RAM 25 stores input data and version numbers of software version changes, etc., and 130M26, to which a backup battery 27 is connected to prevent data loss, stores a control program and this control program. virgin gin number.

The printing exposure calculation formula, etc. is stored, and when the software version is changed, a new RO'M that stores this information is saved.
will be exchanged.

FIG. 1 shows a flowchart when starting up the system. When a power switch (not shown) of the printer processor 10 is turned on, the version number written in the RAM 25 and the version number stored in the ROM 26 are read out. If both version numbers are the same, it is determined that the software version has not been changed. In this case, the ROM

If the two version numbers do not match, the ROM

to be displayed. When the software version is changed, the address of the data in the RAM changes accordingly. Therefore, while the version change is being displayed, the data stored in the RAM 25 is rewritten. This is done by the CPU 23 reading a data writing program from the ROM 26, reading the data stored in the RAM 25 according to this program, and writing it to a new address.

Next, precautions and operation details of the new version are read out from the ROM 26 according to the operating procedure, and displayed on the display 17. Keeping this precaution in mind, the keyboard 1
6 and input data according to the operation details. After inputting the necessary data, the next operation details are displayed on the display 17, and the next data is input according to the operation details. When all operations are completed by repeating this, the new version number is written into the RAM 25.

After this, the photo printing operation can be started as described above.

In addition, like the consumption of the backup battery 27, the RAM 2
Even if the data of 5 is lost, the version change will be displayed as in the case of ROM replacement.

〔Effect of the invention〕

As explained in detail above, according to the present invention, when a ROM is replaced, the version change is automatically displayed, the data writing position in the RAM is automatically changed, and then the precautions and operations are performed. Since the contents are displayed sequentially according to the operating procedure, changing the software version is easy and there is no risk of operating errors.
