Abstract

PURPOSE:To prevent recording paper from being fed unnecessarily during transmission, by allowing the same motor to drive a readout platen roller and a recording platen roller, and providing an electromagnetic clutch which is operated by a received signal on the shaft of the recording platen roller. CONSTITUTION:During transmission, the rotation of a driving motor 9 is transmitted to pulleys 11 and 12 through timing belts 13 and 14 to turn both pulleys at the same time. Consequently, a readout platen roller 2 coupled directly with the pulley 11 rotates clockwise to convey an original. An electromagnetic clutch (not shown in the figure), however, is provided between the pulley 12 and recording platen roller 5, so even if the pulley 12 rotates, the roller 5 is not rotated, so that recording paper is not fed unnecessarily during the transmission. Once a received signal is inputted, said clutch operates to couple the pulley 12 with the recording platen roller 5, feeding the recording paper 7.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transceiver-type facsimile device that incorporates a transmitting system and a receiving system, and is capable of transmitting and transmitting without causing problems such as unnecessary feeding of roll recording paper during transmission.
It is an object of the present invention to provide a facsimile machine that can share a driving source for a receiving system and can be made more compact.

An embodiment of the present invention will be described based on the drawings.

First, there is a reading platen roller (2) at the bottom of the housing (1).
and the same-size sensor (3) are provided facing each other, and the document table (
4) Platen roller (2) that reads the original inserted from the side
A transmitting system is configured in which the image is read by a sensor (3) of equal size while being read and conveyed by the sensor (3). In addition, a recording platen roller (5) and a thermal head (6) are provided facing each other in the lower part of the housing (1), and record the rolled recording paper (7) stored in the lower part of the document table (4). A reception system is configured in which the paper is drawn out and conveyed by a platen roller (5), received and recorded by a thermal head (6), and discharged onto a tray (8). One drive motor (9) is provided, and the motor pulley C1O of this drive motor (9), the pulley α of the reading platen roller (2), and the recording platen roller (5
) between the pulley α and the timing belt α.
Wharf 04 is being spanned. Now, if we look at the recording platen roller (5), its axis (
C) is rotatably supported by a frame αQ, and an electromagnetic clutch αη operated by a received signal is provided on this shaft (C).

In such a configuration, the drive motor (9) rotates in the same direction for both transmission and reception. now,
If a transmission signal is input, the motor pulley (1
00 rotation is transmitted by the timing belt a3α◆, and the pulley (1η) rotates at the same time.This causes the reading platen roller (2) directly connected to the
is rotated clockwise to transport the inserted original, and a transmission operation is performed. On the other hand, the pulley (
Even if 2) is rotating, the electromagnetic clutch Q'/) does not operate depending on the transmission number, so the rotation of the pulley 0 is not transmitted to the shaft α54C, and the recording platen roller (5) does not rotate. Therefore, during the transmission operation, the rolled recording paper (
7) will not be drawn out unnecessarily.

Similarly, during reception when a reception signal is input, the pulley C1◇(C) simultaneously rotates in response to the rotation of the motor pulley H. At this time, the received signal activates the electromagnetic clutch α force, so the rotation of the goo IJ (4'2) is transmitted to the shaft (g), and the recording platen roller (5) is rotationally driven in the clockwise direction. The reception operation is performed while the recording paper (7) is fully drawn out. On the other hand, the rotation of the pulley α■ rotates the reading platen roller (2) in the same way as during transmission, but this is not a problem since it is during reception and there is no document.

Since the present invention is configured as described above, it is possible to unify the drive motors of the transmission and reception systems into one with a minimum number of parts, just by providing an electromagnetic clutch that operates based on a received signal on the recording platen roller shaft. , it is possible to eliminate unnecessary withdrawal of rolled recording paper at the time of transmission, and it is possible to provide a more compact transceiver type facsimile device.
