The printer unit 1-11 converts each color data into binary data and prints in color when a multi-valued signal of each color of CMYK is input, and prints in black and white when the binary data is input.

FIG. 2 is a plan view showing the appearance of the operation panel 1-8 in this embodiment.

The numeric keypad 2-1 is 12 of 0-9, #, *.
It is composed of various types of keys and is mainly used as a means for inputting telephone numbers.

The LCD display section 2-2 displays a display for confirming the state of the apparatus, communication information, and input of a telephone number.

The one-touch key 2-3 is previously stored in the RAM1-
It is used when the destination number written in 3 is read and one-touch transmission is performed. Start key 2-4
Is for starting various operations such as transmission, and the stop key 2-5 is for stopping various operations.

The color key 2-6 is used to read an original as a color original. For example, if there is a four-page original, and the third page is a color original, then 2
Press the color key while loading the page. This indicates that the page to be read next is a color original. A lamp is attached to the inside of this key, and the key is repeatedly turned on and off each time the key is pressed. When reading a page, this lamp is checked, and when it is lit, it is stored as a color original, and when it is off, it is stored as a black and white original.

The resolution selection keys 2-7 are used to switch the resolution at the time of reading an original, and each time the key is pressed, the standard (lamp is off), fine (lamp next to the fine character is on), and super fine (light is on). The lamp next to the word Superfine lights up) and three modes are switched.

Each time the transmission mode switching key 2-8 is pressed, memory transmission (a method in which all the originals are stored in the memory before transmission, the lamp next to the characters in the memory is lit at this time), direct transmission (the original is read) While sending, the lamp next to the direct characters at this time lights up)
And two modes are switched.

In this embodiment, the two lamps are used for the memory transmission and the direct transmission, but one lamp is used and one of them is treated as the default (for example, the memory transmission is set to the default). ),
The lamp may be turned on only at the other time (for example, direct transmission).

3 and 4 are flowcharts showing the operation of direct transmission in this embodiment.

In S301, the transmission mode switching key 2-8 is operated to set the transmission mode to direct transmission. Then, the manuscript on the manuscript table is placed, and the telephone number of the other party is input with the ten keys 2-1 or the one-touch key 2-3.

In S302, the start key 2-4 is pressed to instruct the start of transmission. This operation is not necessary when the other party is designated by the one-touch key 2-3 in S301. Next, in S303, MODEM1-5,
Dialing is done to the other party via NCU1-6.

In S304, a DIS signal is received from the partner machine. The DIS signal includes information indicating the function of the partner device, including whether or not color communication is possible.

In step S305, it is checked whether the lamp inside is lit due to the color key 2-6 being pressed. This means that the operator is instructed to read the original as a color original.

If the color reading instruction is not given in S305, it is black and white reading. Therefore, in S309, the coding mode at the time of reading is set to binary black and white.

If a color reading instruction is given in S305, it is checked in S306 whether the DIS received in S304 has a declaration of a color communication function. If there is no declaration, color documents cannot be communicated, so in order to send them as black and white documents, S309
In, the encoding mode at the time of reading is set to binary black and white.

After the encoding mode is set to binary black and white in S309, a DCS for instructing monochrome transmission is created and transmitted in S310.

If it is determined in S306 that the color communication function of the partner machine is available, color communication is possible.
In 307, the encoding mode at the time of reading is JPEG
To Subsequently, in S308, the color transmission instruction D

If the monochrome transmission mode is set as the default, the display in S605 may not be performed. If color reading is instructed, S60
In 2, it is checked whether the encoding mode is JPEG.

If it is JPEG, color transmission is being carried out, so in S603, it is determined that color transmission is in progress.
Displayed on the LCD to notify the operator. If it is not JPEG, it is being sent as a black-and-white binary original even if there is an instruction for color transmission. Therefore, in S604, the fact that the color original is being sent as monochrome transmission is displayed on the LCD 2-2 to notify the operator. .

FIG. 8 is a flow chart showing the operation of the display processing S509 in the memory transmission mode described above.

In step S701, it is checked whether the page to be transmitted at the time of reading is stored as a color page. This means that the operator gave a color reading instruction when reading the original. If it is not stored as a color page, it is displayed that a black and white document is being transmitted, and the process ends. It should be noted that if the case of transmitting a black-and-white original is considered as the default, nothing may be displayed.

If it is stored as a color page, it is stored as a color page in S702, and JP
It is checked whether or not the EG-coded color image is converted into a monochrome binary image. If it has not been converted, color transmission is being performed. Therefore, in S703, color original transmission and LCD2-
