2. Description of the Related Art FIG. 1 is a side view showing a main part of a driving unit of a facsimile. A reading head 4 and a recording head 5 are elastically mounted by springs 6 and 7 so as to correspond to both sides of a roller 3 that transports the original 1 and the recording paper 2, and the reading head pin 8 is integrally fastened to a bracket 9. The reading head 4 is fastened to the bracket 9 with a screw (not shown). A recording head pin 10 is integrally fastened to the recording head 5, and a cam 12 including a long shaft portion 11a and a short shaft portion 11b is fixed to both ends of a shaft 12 inside a hollow roller 8. Is attached, the cam rotates when the motor (not shown) rotates forward,
When it rotates in the reverse direction, the rotation of the cam is interrupted and the roller 3 rotates.

Conventionally, in the standby mode, the reading head pin 8 and the recording head pin 10 are connected to the long shaft portion 11a of the cam 11 to separate the reading head 4 and the recording head 5 from the roller 3.

When a transmission mode is selected to transmit the contents of the document 1 in this state, the cam 11 fixed to the shaft 12 rotates according to the selected mode to connect the reading head 4 to the roller 3. , The recording head 5 is the roller 3
Will be kept separate from. After that, when the roller 3 is rotated by the reverse rotation of the mode, the original 1 is read by the reading head 4 while being fed, so that the original 1 can be transmitted. When the transmission of the original 1 is completed, the mode rotates the shaft 12 in the forward direction, so that the reading head 4 and the recording head 5 are separated from the standby mode, that is, the roller 3.

When the receiving mode is selected, the cam 11 fixed to the shaft 12 rotates according to the selected mode to connect the recording head 5 to the roller 3, and the reading head 4 is separated from the roller 3. Will be maintained. After that, when the roller 3 rotates due to the reverse rotation of the mode, the recording head 5 records the received content on the recording paper 2 that is transported. When the reception is completed, the mode shaft 12 is rotated in the forward direction, so that the reading head 4 and the recording head 5 are separated from the roller 3 in the standby mode.

On the other hand, when the copy mode is selected, the short shaft portion 11b is connected to the reading head pin 8 and the recording head pin 10 by the rotation of the cam 11 fixed to the shaft 12 according to the selected mode, and the reading head 4 and the reading head 4 are connected. Since the recording head 5 remains connected to the roller 3, the content of the fed original 1 is recorded on the recording paper 2. Chart paper 2
When the copying is completed, the mode rotates the shaft 12 in the forward direction, so that the mode becomes the standby mode.

When the product is shipped or stored for a long period of time, the reading head 4 and the recording head 5 are operated in the standby mode.
The recording paper 2 is removed in a state where the recording paper 2 is separated from the roller 3.

[0008]

However, such a conventional driving method has the following problems. 1. Since the reading head 4 is kept separated from the roller 3 in the standby mode, when the document is set in the transmission mode, the leading edge of the document is inserted past the reading portion to a position where it is connected to the roller, and therefore Contents at the tip are not sent. 2. In the case of a manual type in which the recording paper is manually cut, since the roller 3 is separated from the recording head 5, the recording paper is unwound when the recording paper is cut. 3. In the standby mode, if the facsimile is shocked,
The leading edge of the recording paper may be displaced from between the roller 3 and the recording head.

The present invention is to solve the above-mentioned problems of the prior art. In the standby mode, the reading head and the recording head are connected to the transfer means, and then the transfer means is selected according to the mode selection. It is an object of the present invention to allow these to mesh simultaneously or selectively so that the leading edge of the original is not transmitted during transmission or the recording paper is unwound when the recording paper is cut.

[0010]

In order to achieve the above object, the present invention provides a standby mode stage in which a reading means and a recording means are connected to a transfer means by a cam means, and a rotation of the cam means in the standby mode step. In the transmission mode stage, in which the reading means is connected to the transport means and the recording means is spaced apart from each other, and in the standby mode step, the recording means is connected to the transport means by the rotation of the cam means and the reading means is spaced apart from the recording paper. A reception mode step for recording the contents received.

According to the present invention, after the recording means is separated from the transfer means by the rotation of the cam means in the standby mode, when the copy signal is input with the leading edge of the original reaching the entrance of the reading means, the cam means further rotates. Further, a reading mode and a recording means may be connected to the transfer means to further include a copy mode step for recording the contents of the original in the recording. The present invention may further comprise a packaging mode step in which the reading means and the recording means are separated from the transfer means by the cam means.

After the transmission is completed, a transmission mode stage in which the cam is rotated in the standby mode,
In the standby mode, the recording head 5 is connected to the roller 3 by the rotation of the cam 11 and the reading head 4 is separated to complete the recording of the content received on the recording paper 2, and then the cam is rotated in the standby mode. And stages.

After the recording head is separated from the roller by the rotation of the cam in the standby mode, when the copy signal is input with the leading edge of the document reaching the entrance of the reading head, the cam further rotates and the roller is rotated. A copy mode step of rotating the cam in the standby mode after the reading head and the recording head are connected to complete the recording of the content of the original on the recording paper may be further provided. Also, a packaging mode step may be further provided in which the reading head and the recording head are separated from the roller by the long axis portion of the cam. Here, the roller is a transfer means, the cam is a mode selection means, and the reading head and the recording head are the reading means and the recording means, respectively.

The above items will be described in more detail below.
2 to 7 are flowcharts for explaining each mode of the present invention, and FIGS. 8 to 12 are side views showing the position of the cam in each mode of FIGS. 2 to 7. When the product is shipped, the reading head 4 and the recording head 5 are the rollers 3.
Stay separate from. Therefore, as shown in FIG. 12, the long shaft portion 11 a of the cam 11 is connected to the reading head pin 8 and the recording head pin 10 and the reading head 4 and the recording head 5 are separated from the roller 3.

As shown in FIG. 2, if the recording paper 2 is not mounted in this state, the cover is opened and the recording paper is mounted. As a result, the recording paper detection sensor is turned off, and the mounting operation of the recording paper is completed when the cover is closed.

After that, when the power is turned on, the cam 11 rotates 90 ° clockwise, so that the reading head pin 8 and the recording head pin 10 are connected to the short shaft portion 11b of the cam 11 as shown in FIG. That is, the reading head 4 and the recording head 5 are connected to the roller 3 in the standby mode. When the transmission mode is selected to transmit the original document in this state, the result is as shown in FIG.

As shown in FIG. 3, when a document to be transmitted in the standby mode is placed on the document table, the document sensing sensor senses the document and turns on, so that the motor rotates the shaft 12 clockwise by 45 °.
The operation is suspended by rotating. As a result, the reading head pin 8 maintains the state in which the short shaft portion 11b of the cam 11 is connected, and the recording head pin 10 is connected to the long shaft portion 11a of the cam 11, so that as shown in FIG. 5 is separated from the roller 3. After the recording head 5 is separated from the roller 3 in this way, the motor rotates in the reverse direction to transfer the document placed on the document table to the reading position and complete the document setting. After that, when the start button is pressed when dialing the recipient's number and making a signal sound, one original document located at the bottom is fed and passes between the roller 3 and the reading head 4, When the document sensor is turned off, the reading head 4 reads and transmits the content recorded on the document.

As described above, when one document is completely transmitted and is ejected to the tray, the presence or absence of the document to be transmitted is determined, and if there is a document, the document detection sensor is turned on to detect the next document. Since it is set, it can be sent continuously.
However, when it is sensed that there is no document to be transmitted, the motor rotates the cam 11 clockwise by 315 ° after 3 to 4 seconds to return to the standby mode as shown in FIG. 8 to interrupt the operation.

FIG. 4 is a diagram for explaining the reception mode. When a reception signal arrives in the standby mode, the motor is driven to rotate the cam 11 clockwise by 135 ° and the operation is interrupted. As a result, the reading head pin 8 is connected to the long shaft portion 11a of the cam 11 as shown in FIG. 10, so that the reading head 4 is separated from the roller 3 and the short shaft portion 11b of the cam is connected to the recording head pin 10. Since the held state is maintained, the recording head 5 is connected to the roller 3.

As described above, when the facsimile telephone is used in common with the ordinary telephone when the received signal is received, the start button is pushed after switching the function. But,
When a facsimile telephone is used, the reading head 4 is separated from the roller 3, and the motor rotates the roller 3 counterclockwise, so that reception starts. When the original is continuously received, and it is sensed that there is no original received after being recorded on the recording paper, that is, when the reception is completed, the operation is interrupted after the cam 11 rotates clockwise by 225 ° to return to the standby mode. To do.

FIG. 5 is a diagram for explaining the copy mode. When a document to be copied in the standby mode is placed on the platen, the document detection sensor senses the document and turns on as in the transmission mode, so the motor rotates the shaft 12 clockwise 45 °.
° Rotate to stop operation. As a result, the reading head pin 8 maintains the state in which the short shaft portion 11b of the cam 11 is connected, and the recording head pin 10 holds the cam 11
The recording head 5 is separated from the roller 3 because the long shaft portion 11a of is connected. After the recording head 5 is separated from the roller 3 in this way, the original placed on the original table is transported to the reading position by the reverse rotation of the motor, so that the setting of the original is completed. After that, when the copy start button is turned on, the motor is driven in the forward direction again to further rotate the cam 11 by 135 ° in the clockwise direction and then the driving is interrupted.
The reading head pin 8 and the recording head pin 10 are simultaneously connected to the short shaft portion 11b of the cam 11, whereby the reading head 4
Also, the recording head 5 is connected to the roller 3. In this state, when one of the documents located at the lowermost position is fed by the reverse rotation of the mode and the content recorded on the document is read by the reading head 4, the read content is recorded by the recording head 5 on the recording paper 2.
To record.

When the reading head 4 finishes reading the original, the original is discharged to the tray side, and the original detection sensor is turned off. After that, if there is a document to be copied again, the document detection sensor is turned on again and the document is continuously set, so that continuous copying becomes possible. However, when there is no original to be copied, the cam 11 rotates 180 ° clockwise by the forward rotation of the motor to return to the standby mode as shown in FIG. 8 and the operation is interrupted.

FIG. 7 is a diagram for explaining a case where the recording paper is used up in the reception or copy mode (hereinafter referred to as exhaustion). When the sensor detects the exhaustion of the recording paper at the time of receiving or copying the original, the cam 11 is rotated 90 ° at the time of reception and 135 ° at the time of copying by the normal rotation of the motor. The head pin 8 and the recording head pin 10 are connected to the long shaft portion 11a of the cam 11 to separate the reading head 4 and the recording head 5 from the roller 3, and the user is notified by a recording paper exhaustion warning means such as a buzzer. Notify that the chart paper has been used up. In the copying mode during the above operation, the document is ejected from the tray as the recording paper exhaustion sensor is turned on. As a result, when the user opens the cover, mounts a new recording paper, and then closes the cover, the sensor for detecting the exhaustion of the recording paper turns off, and the cam rotates 90 ° clockwise, as shown in FIG. Return to standby mode and suspend operation.

FIG. 6 is a drawing for explaining packaging at the time of shipment or storage for a long period of time. When the cover is opened to remove the recording paper inside the device in standby mode,
Since the cam rotates clockwise by 270 ° due to the normal rotation of the motor, the state is as shown in FIG. 12 similarly to when the recording paper is used up during reception or copying. That is, the reading head 4 and the recording head 5 are separated from the roller 3. Thus, when the recording paper is removed and the cover is closed in the device, the recording paper detection sensor detects that there is no recording paper and maintains the state in which the reading head 4 and the recording head 5 are separated from the roller 3. Therefore, by turning off the power and packaging, the product can be shipped as well as stored. After that, at the time of reuse, the recording paper is mounted in the device by the operation shown in FIG.
