Also, when facsimile transmission is performed, facsimile data is transmitted via the modem and NCU 49. Further, when receiving a facsimile, the facsimile data is received via the NCU 49 and the modem 48.

Further, in the present embodiment, the modem 48 can send and receive electronic mail with a specific provider. This is to send and receive an electronic mail by communicating a command for sending and receiving an electronic mail as facsimile data with the specific provider.

Further, in the facsimile 1 of this embodiment,
A CCD line sensor 52 and a read image processing LSI 51 are provided, and an image of a document read by the CCD line sensor 52 is processed by the read image processing LSI 51 and output to the ASIC 40 as data. AS

The SI 63 is provided, and the key code output from the keyboard 4 can be input.

When the UART LSI 63 receives the key code from the keyboard 4, the UART
An interrupt signal is output from the LSI 63. as a result,
The ASIC 40 executes interrupt processing related to this interrupt signal. Specifically, the key code is read from the UART LSI 63 and once the serial reception buffer 6 is read.
Store in 1. Further, since it is necessary to return the ACK code indicating that the data has been received to the keyboard 4, the ACK code corresponding to the received key code is stored in the serial transmission buffer. Serial reception buffer 61

A RAM 59 is connected to the ASIC 40. The RAM 59 includes a key buffer unit 60,
Serial reception buffer 61 and serial transmission buffer 6
Divided into 2nd class.

The key buffer unit 60 is provided for each of the keys 4 described above.
Key code corresponding to 4 and serial reception buffer 6
The key code from the keyboard 4 stored in 1 is stored. In the present embodiment, as an example, one key code is composed of 1 byte, and the key buffer is 16 bytes.
The capacity for bytes is secured.

The serial reception buffer 61 has the above-mentioned U
This is an area for storing the key code received by the ART LSI 63. The data stored in the serial reception buffer 61 is regularly monitored by the storage program. When the key code is stored, the key code is read and stored in the key buffer 60.

The serial transmission buffer 62 has the above-mentioned U.
This is an area for storing data to be transmitted to the keyboard 4 via the ART LSI 63. When the keyboard 4 does not receive the ACK code for the transmitted key code, it does not transmit the next key code even if key input is performed. Therefore, an ACK corresponding to the key code stored in the serial reception buffer 61
The code is stored in this serial transmission buffer 62. The presence or absence of data in the serial transmission buffer 62 is regularly monitored by the transmission program, and when the data is stored, the transmission program UARTs.
It is transmitted to the keyboard 4 via the LSI 63.

Further, in the facsimile 1 of this embodiment,
A speaker 64 is provided and is configured to be able to output a received audio signal and the like. The control of this audio signal is also AS
It is performed by IC40.

Next, the input processing of the keyboard 4 in the facsimile machine 1 of the present embodiment configured as described above will be described in detail with reference to the flowchart of FIG.

In the above-described facsimile 1 of the present embodiment, the keyboard 4 can be freely connected to or disconnected from the facsimile 1. That is,
Data storage program in serial reception buffer 61,
The program for storing the data stored in the serial reception buffer 61 in the key buffer 60, the program for storing the data in the serial transmission buffer 62, and the transmission program for the data stored in the serial transmission buffer 62 via the UART LSI 63 are the keyboard 4 is executed regardless of connection, but if no data is received by the UART LSI 63, the UART LSI
Since the interrupt signal is not output from 63, the data is not stored in the key buffer 60 and does not affect other processing. However, the keyboard 4
When is connected, the communication with the keyboard 4 can be surely performed, so that the data input from the keyboard 4 can be surely performed.

First, when the user performs a key input using the keyboard 4, the key code corresponding to each key is output from the keyboard 4 and is temporarily stored in the memory in the UART LSI 63. Next, the UART LSI 63
An interrupt signal is generated to the SIC 40 to notify that there is an output from the keyboard 4. ASIC40
When receives the interrupt signal, the interrupt process shown in the flowchart of FIG. 3 is executed (step S1).

When the above process is started, the ASIC 40
Inputs the key code stored in the memory in the UART LSI 63 and stores it in the serial reception buffer 61 as needed. Then, the contents of the serial reception buffer 61 are read, and it is determined whether the input identified by the key code is valid (step S2). This is because key input itself is not permitted depending on the mode. For example, even if any key input is made on the keyboard 4 in the normal call mode or the facsimile transmission mode, this key input is invalid and ignored (step S2; NO). However, in the standby mode, when the function key for switching from the keyboard 4 to the electronic mail creating mode is input, it is treated as a valid key input (step S2; YES). Alternatively, in the e-mail creation mode, even if there is an input with a character key from the keyboard, it is treated as valid key input (step S2; YES).

When it is determined that the key input is valid (step S2; YES), the ASIC 40 uses the keyboard 4
The information transmitted from is analyzed (step S3), and the key data is grasped from the transmitted information (step S4). For example, when some command is composed of a combination of a plurality of keys, it is determined whether or not the combination is correct. If the combination is correct, it is determined to be valid (step S5; YE).
S). Further, for example, in the e-mail text creation mode, when a function key other than the character key is input, it is invalidated and ignored (step S5; NO).

When it is determined that the key data is valid (step S5; YES), the ASIC 40 stores the key code stored in the serial reception buffer 61 in the key buffer 60 (step S6).

Since the present embodiment is configured as described above, the ASIC 40 which executes the program for reading the key code can perform the same processing as when the cursor key is pressed.

For example, the function key 2 on the panel 5
When 7 is pressed, the electronic mail creation / transmission mode is entered, and the numeric keypad 20 on the panel 5 can be used to create the electronic mail text. In this processing, the key code output from the panel GA 45 is temporarily stored in the key buffer 60, and the character corresponding to the key code stored in the key buffer 60 is displayed on the LCD panel 23 or created as a text sentence. Is.

Therefore, in the electronic mail creating / sending mode, even when there is a key input from the keyboard 4, the characters corresponding to the key code output from the keyboard 4 are displayed on the LCD panel 23 and created as a text sentence. Will be done.

As described above, according to this embodiment, even when the keyboard 4 which is easy to operate and can be input at high speed is provided, the control program for the key code reading process can be used as it is. Therefore, it is possible to significantly reduce the cost for program development.

In the present embodiment, an example using a facsimile has been described as an example of the electronic device of the present invention, but the present invention is not limited to such a configuration, and for example, an electronic mail is transmitted. The present invention can be applied to various electronic devices such as mobile phones.
