The present invention relates to a facsimile composition device, and more particularly, to a facsimile drive device capable of operating a cutter (paper cutter) and a paper feed roller as one drive motor.

The facsimile machine in which thermal recording paper is embedded in the form of a roll is used to operate a paper feed roller that transfers thermal recording paper and a cutter to cut the recorded thermal recording paper when copying a signal or an original received from outside. Each drive source is provided. However, when each drive unit for driving the transfer roller and the cutter is installed, not only the arrangement of each member in the machine is complicated, but also a number of disadvantages occur such as an increase in cost by installing and using a plurality of drive units.

Therefore, the present invention is configured to press each of the paper feed pulley, the shaft, the cutter operation pulley and the shaft and press the known anti-rotation bearing to operate each member by using one drive motor and a belt. The purpose is to provide a facsimile drive.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings, FIG. 1 is an internal planar configuration diagram of a facsimile drive unit using the present invention. In detail, the drive pulley 3 and cutter of the drive motor 2 The paper feed pulley 4 coupled to the end of the operation pulley 5 and the paper feed roller 4 'is connected as a belt 4 to each other. The left side of the paper feed pulley 4 has a paper feed roller 4 'coated with rubber on the shaft circumferential surface, and the upper portion of the paper feed roller 4' receives an external signal to print on the thermal recording paper 1. Thermal Head (9) with the ability to record the position is located. On the left side (or front end) of the paper feed roller 4, it is connected to the lower cutter 7 'fixed to the frame 11, and a link 8 which moves according to the rotation of the cutter operation pulley 5; Each of the upper cutters 7 is provided, and the thermal recording paper 1 wound in a roll shape is placed on the right side (or rear end) of the driving unit.

On the other hand, a known anti-rotation bearing 12 is press-fitted between the shaft surface and each pulley in which the paper feed pulley 4 and the cutter operation pulley 5 are installed. In the following description, the paper feed pulley 4 and The structure of the shaft, the anti-rotation bearing 12 will be briefly described.

2A and 2B are assembly cross-sectional views between the paper feed pulley 4 and the paper feed rollers 4 'and cross-sectional views between the cutter operation pulley and its shaft.

The paper feed pulley 4 is penetrated on the shaft circumferential surface extending from the paper feed roller 4 ', and a known reverse rotation prevention bearing 12 is press-fitted into the shaft and the paper feed pulley 4 inner surface. The anti-rotation bearing 12 is called a one way clutch and is locked in only one direction so that the paper feed pulley 4 rotates while holding the shaft only when the paper feed pulley 4 rotates in that direction by the belt. When the shaft makes the same rotation but the paper feed pulley 4 rotates in the opposite direction, only the paper feed pulley 4 and the bearing 12 rotate while the shaft is fixed. That is, even if the paper feed pulley 4 rotates, the paper feed rollers 4 'in the extended state are not rotated.

The paper feed pulley (4) and shaft used in the present invention, the cutter operation pulley (5) and each of the anti-rotation bearings 12 and 12 'pressed into the shaft have the opposite locking directions. When the driving motor 2 of the motor rotates in the arrow direction (locking direction of the bearing shown in Fig. 2a), the paper feed pulley 4 and the paper feed roller 4 'are rotated in the same direction by the belt. However, even if the cutter operation pulley 5 rotates, the shaft in the cutter operation pulley 5 is not rotated by the anti-rotation bearing 12 ', so that the link 6 connected to the shaft does not linearly move. That is, when the paper feed roller 4 'rotates, the cutter operation pulley 5 is idling about the fixed shaft and the cutter does not operate. On the contrary, in the state where recording is completed, when the rotational motion of the drive motor is opposite to that described above (locking direction of the bearing shown in FIG. 2B), the paper feed pulley 4 is idle and the cutter operation pulley 5 ) And its shaft are rotated.

Looking at the operation of the present invention configured as described above, FIG. 3 is a right side view of FIG. 1, for convenience, omitting the drive motor 2 of FIG.

When a signal is received from the outside or a copy is transmitted, the drive motor is operated by a known electronic circuit. When the drive pulley 3 rotates clockwise, the belt 6 also feeds the paper feed pulley 4 and the cutter. The operation pulley 5 also rotates in the same direction. At this time, when the paper feed pulley 4 is rotated in the clockwise direction as described in FIGS. 2 a and 2b, the paper feed pulley 4 and the paper feed roller 4 'are integrated to form the paper feed roller 4'. ) Is also rotated clockwise, the thermal recording paper 1 in contact with the circumferential surface of the paper feed roller 4 'is transferred in the direction shown in the drawing (the thermal recording paper 1 is thermally stopped while It rotates itself in accordance with the movement of the recording sheet 1). At this time, characters are recorded on the thermal recording paper 1 by the thermal head 9.

While the paper feed pulley 4 and the paper feed roller 4 'perform this function, the cutter action pulley 5 also rotates clockwise, but is idling about the fixed shaft. The link 8 connected to the end and the upper cutter 7 connected to the link 8 are in a stopped state.

When the recording is completed on the thermal recording paper 1 and the driving motor is rotated counterclockwise by the electronic circuit, the paper conveying pulley 4 is operated with respect to the shaft. Idle rotation occurs according to the rotational direction, and thus self-rotation and transfer of the thermal recording paper 1 are also stopped. Since the cutter operation pulley 5 rotates counterclockwise while holding the shaft by the anti-rotation bearing, the link 8 fixed to the shaft end has a linear reciprocating motion in the direction of the arrow shown in the drawing. As a result, the upper cutter 7 is interlocked with the lower cutter 7 'to cut the thermal recording paper 1 on which the recording between the upper cutter 7 and the lower cutter 7' is completed.

The present invention can press the paper feed pulley and shaft, the cutter operation pulley and the shaft to prevent the reverse rotation of each bearing as a single drive motor to control the continuous operation of each member to effectively operate the internal structure of the machine In addition, it is possible to obtain an excellent economic effect compared to the method using two drive sources.
