It is transferred inside the machine body. In this case, the inserted document is conveyed one by one, the frictional force of the original 202 in contact with the automatic sheet feed roller 208 is the friction between the original 202 and the original 202, or the original 202 The document 202 is conveyed in the direction of the driving roller 212 by the automatic paper feed roller 208 because it is larger than the friction force between the rubber pad 206 and the rubber pad 206. Therefore, the transferred document 202 is transferred to an image sensor 216 that reads and transmits data by rotating the driving roller 212 and the pinch roller 210. At this time, the white roller 214 installed on the upper part of the image sensor 216 inquires the reference data before reading the data for the original 202, and transfers the original 202 using the friction force. Therefore, when the document 202 is transferred by the white roller 214, the document is read by the image sensor 216, and the reading process is carried out by being transferred by the exit roller 220 and the pinch roller 218 afterwards. Is done.

However, since the conventional facsimile structure as described above can read only one side of the document, when the inserted original is the original written on both sides, the user changes the original by one side, and the support stand 204 is used. There was a problem with having to reinsert it into the.

Referring to FIG. 1, first, a central processing unit (hereinafter referred to as a central processing unit) 100 controls overall operations of a system according to a predetermined program. The memory unit 102 stores a control program for controlling the system and image data to be transmitted, and stores message image data transmitted from the outside. The OPE 104 has numeric keys and various function keys and has an LCD display to display the status of the system. The double-sided scanner 106 reads the original, converts the image of the original into secondary information, and applies it to the central processing unit 100. In this case, the double-sided scanner 106 positions the rear reading unit at the front end of the document based on the document transfer direction, and positions the front reading unit at the rear end of the document to read the data recorded on the rear side of the original when the document is transferred. After reading, read the data recorded on the front. The modem 108 modulates the input / output signal of the central processing unit 100. The network control unit (NCU) 110 forms a call path between the call line and the modem 108 under the control of the central processing unit 100. The printer 112 prints the information output from the central processing unit 100. The document insertion sensor unit 114 detects the state of the document and the recording paper and informs the central processing unit 100.

Therefore, in order to describe the configuration of the above-described double-sided scanner 106 in more detail, a mechanical schematic diagram as shown in FIG. 3 is attached.
