PURPOSE:To drive a reciprocatingly linear driving mechanism by utilizing the rotation of the supporting shaft and to prevent the occurrence of inferior contact, by constitut ing the supporting shaft in such a way that it can rotate integrally with the photosensi tive body and driving the reciprocatingly linear driving mechanism by means of the rotation of the supporting shaft. CONSTITUTION:A photosensitive body supporting shaft 2 is fitted to a side plate 11 and aligning plate 14 by means of bearings 11a and 14a freely and rotatably and the supporting shaft 2 is made top rotate in the same direction integrally with a photosensitive body 1 by fixing a gear 5 to the supporting shaft 2 with a screw 5a, etc. Then a gear 8 united with a cam 7 integrally is rotated by means of a cam driving gear 16 fitted to the end section of the supporting shaft 2 opposite to the gear 5 as a rotation preventing means through gears 17 and 18 provided freely and rotatably to the aligning plate 14 by a shaft 19. Therefore, this device can be manufactured in a unit and its assembling property is excellent. Moreover, since a current collector 4 for connecting a temperature maintaining heater 20 in the photosensitive body 1 with an external power source can be arranged one end section of the supporting shaft 2, the occurrence of inferior contact caused by the movement of the photosensi tive body 1 in the axial direction can be eliminated. |
