Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a facsimile device, and more particularly to a facsimile device controlled by a microcomputer.

[Prior Art] In a facsimile device that performs sequence control using a microcomputer, a program for performing sequence control is stored in a storage element such as a ROM (read-only memory).

Such programs often contain programming errors called bugs.

On the other hand, even if the facsimile machine is the same model, products with different program versions are available on the market depending on the date of manufacture.

Therefore, which facsimile device has which version?
The only way to find out whether a ROM was installed was to disassemble the device and look at the sticker with the edition name attached to the ROM, or to check the contents electrically.

For service personnel, the repair method differs depending on which version of ROM is installed in the device.
An important issue is how to easily know the edition name.

[Objective] The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a simple and inexpensive facsimile device that allows program version information to be known with a simple operation. A further object of the present invention is to provide a facsimile device that can easily diagnose communication errors caused by program bugs.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

FIG. 1 and the following illustrate one embodiment of the present invention, and FIG. 1 shows a block diagram of a control circuit.

In Figure 1, the number 1 indicates the CPU (Central Processing Unit), which controls the entire facsimile machine.
Follow the program written in ROM2.

What is indicated by code 3 is memory for images.
RAM (Random Access Memory), and what is indicated by reference numeral 4 is a timer.

On the other hand, those indicated by symbols 5 to 10 are input/output ports, and input/output port 5 has a modem controller 11.
A modem 12 is connected via the modem 1
2 is connected to a line 12a.

A network control device 13 is also connected to the input/output port 5.

An operation panel 14 and various sensors 15 are connected to the input/output port 6.

A motor driver 16 is connected to the input/output port 7 and controls the rotation of a motor (not shown) that drives a roller 16a that moves the document 24.

A light source 23 is connected to the input/output port 7 via a lamp driver 17, and the reflected image of the document 24 illuminated by the light source 23 is transmitted to the image reading element 2.
2 and input to the input/output port 8 via the video amplifier 17.

A thermal head 26 is also connected to the input/output port 9 via a head driver 19.

Recording is performed on the recording paper 25 by the thermal head 26.

A cutter 27 is connected to the input/output port 10 via a cutter driver 20, and cuts the recording paper 25 at a desired position.

In addition, the input/output port 10 has a motor driver 21.
is connected to the roller 21 that feeds the recording paper 25.
Controls the rotation of the motor that drives a.

Based on the above configuration, the light source 23 is
illuminates the original 24 and reads the original image with the element 22,
From input/output port 8 via video amplifier 17
Store it in RAM3.

After this image information is encoded in a predetermined manner, it is modulated by the modem 12 via the input/output port 5 and sent to the line.

On the other hand, at the time of reception, image information is received from the line 12a, demodulated by the modem 12, and input/output port 5
The image data is obtained through the decoder, and after being decoded, it is recorded on the recording paper 25 by the thermal head 26.

By the way, the facsimile apparatus starts its predetermined operation depending on the presence or absence of a document to be transmitted or copied, the handset being turned up or down, the start switch being turned on or off, the ringing tone from the line, etc.

Then, it is determined which process to perform based on the various information mentioned above.

The flow of this process is shown in the flowchart of FIG.

That is, initialization is first performed in step S1, and it is determined in step S2 whether or not the test switch is on. If it is on, a test is performed, and if it is not on, the process proceeds to step S3 and the Ci (Calling indicator) In other words, it is determined whether or not there is automatic reception, and if YES, recording is started, if NO, the process advances to step S4, and if the telephone switch is on, the receiver is placed in step S5. It is determined whether or not the value is rising, and if it is rising, a call is made, and if it is falling, the control is terminated.

Further, if the telephone switch is not on in step S4, the process advances to step S6, and if the start switch is on, it is determined in step S7 whether or not the telephone receiver is on.

If the receiver is off, the process advances to step S8 to determine whether or not there is a document, and if there is no document, the version name of the ROM version is recorded on the recording paper 25 by the thermal head 26 in step S9, and the recording is performed. The paper is fed and cut by the cutter 27, and the control ends.

Further, if the telephone receiver is picked up in step S7, the process advances to step S10, where it is determined whether or not there is a document.

On the other hand, FIG. 3 shows a memory map of the ROM2.

In FIG. 3, a program for controlling the operation of the facsimile is written in area A from addresses A ₀ to _{B 0} -1.

Further, in area B from addresses B ₀ to C ₀ -1, characters for displaying an error display, an ID display, or a ROM version are written.

Furthermore, an area C indicated by addresses C ₀ - contains ROM version information.

At step S9 in FIG. 2 for recording the ROM version, the CPU 1 shown in FIG. 1 looks at the information in area C, selects a corresponding character character from area B, and records it on the recording paper.

In this way, the version name of the memory element containing the program used in the facsimile can be known very easily and reliably.

Incidentally, an example of character characters written in area B of the memory map of the ROM 2 is shown in FIG.

Incidentally, in the above-described embodiment, a structure was adopted in which the version name of the ROM was written on the memory paper, but this can be modified to display numbers and letters on the operation panel using a liquid crystal or LED. You can also do that.

Furthermore, if a structure is adopted in which, if an error occurs during the communication procedure of the facsimile device, the error is displayed on recording paper and the process is stopped, the version of the ROM can be displayed at any time.

In other words, if you want to know the version of the ROM, this is extremely convenient since it is when some kind of error occurs.

[Effects] As is clear from the above description, according to the present invention, information indicating the version of the program is stored in the program memory, and when a communication error occurs, the recording paper on which the received image is recorded can be used. In order to record the information indicating the version of the program, the information indicating the version in the program memory is recorded, using the configuration that normally records the received image. The device configuration is simpler and cheaper than a device with a dedicated configuration, and since information indicating the version is recorded when a communication error occurs, there is no need for the operator to perform any special operations, increasing efficiency. This has the advantage of being able to easily know the version of the program and easily diagnosing communication errors caused by bugs in the program.
