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 will switch on next to the word Superfine) and the mode will switch.

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 the mode switches.

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). Alternatively, 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,
