The present invention relates to a stable driving device of an electronic copier, and more particularly, to a stable driving device that can prevent the vibration of the main body by absorbing the shock applied to the frame of the main body.

Conventionally, the optical system absorbs the impact of the optical system by attaching a sponge to the frame at the beginning and the end of the forward and backward direction. Such a conventional copier stable driving means passes the maximum distance that the optical system can copy and the controller moves forward. When the clutch is controlled, the optical system advances by inertia, and then collides with the sponge. After that, the reverse clutch is operated to reverse the optical system, and after the optical system passes the copy start position, when the controller controls the reverse clutch, the optical system advances by inertia and then After the collision, the reverse clutch is operated to reverse the optical system, and after the optical system passes the start position of the radiation, if the controller controls the reverse clutch, the optical system reverses by inertia and impinges on the sponge. Virtually no friction The impact of the optics just passed the main door there was a defect that causes vibrations. Therefore, the sponge mainly contributed to the noise prevention role.

In addition, a circuit that can adjust the input current of the optical drive motor is configured to absorb the shock of the optical system, but this is not only a difficult means of construction, but also a defect that the drive motor is easily damaged due to back electromotive force generated in the drive motor. There was this.

The present invention devised to solve such a conventional defect is to provide a device that absorbs the shock of the optical system well without changing the input current of the drive motor, and provides a device that reduces the noise when the impact, When described in detail with the accompanying drawings as follows.

As shown in FIG. 1 and FIG. 2, in constructing the safety drive device of the electronic copier, upper and lower portions of the base 2 having a predetermined width and length attached to the frame 1, 1 'of the main body are provided. While moving between the guide bars 3, 3 'and inserting the moving bodies 5, 5' with the insertion holes 4, 4 'in the center, Between the intermediate portion of the pedestal 2, that is, between the two guideways (3) and 3 ', the support section (6) protrudes in the same direction as the two guide sections (3) (3') and the support section (6). At the distal end of the U-shaped guide grooves 7 and 7 ', the intermediate portions of the actuating levers 8, which are cut out on both sides, are fitted with the shaft pins 9, so that both guide grooves 7 of the actuating levers 8 ( 7 ') inserts moving pins 10 and 10' protruding from the middle of the outer circumferential surface of the moving bodies 5 and 5 ', respectively, and guides between the two moving bodies 5 and 5' and the pedestal 2. The coil springs 11 and 11 'fitted to the inner side of the liver 3 and 3' are interposed, and reference numerals 12 and 13 in the drawings denote the first and the second. Will showing a (Mirror), 14 will showing a wire for transferring, 15 is shown a drive pulley.

The effect of the present invention thus achieved is as follows.

When no force is applied from the outside, as shown by the solid line of FIG. 2, the operating lever 8 is in a vertical state, and the first mirror 12 of FIG. 1 collides with the upper movable body 5 so that the second As shown by the imaginary line of FIG. 5, when the upper movable body 5 moves inward along the upper guide section 3, the upper spring 11 is compressed and the operating lever 8 is clockwise around the shaft pin 9. The lower movable body 5 'is moved to the outside along the lower guide section 3' and the lower spring 11 'is tensioned, so that the impact force by the first mirror 12 during the process is Since the spring 3 is cushioned by the elastic force, the frame 1 of the main body is not vibrated.

On the other hand, when the first mirror 12 is transferred in the opposite direction can be moved smoothly by the restoring elastic force of the upper spring (11).

The present invention, as described above, reduces the shock vibration by absorbing the impact force of the optical system applied to the main body by the elasticity of the two springs, and can give the reverse propulsion force of the optical system by the restoring elastic force of the spring during the reverse movement of the optical system. There is an advantage of making it smooth.
