发明名称 IMAGE FORMING DEVIE
摘要 PURPOSE:To reduce the number of parts and the cost of the title device by driving an indicating means and a shutter means by the sam driving source. CONSTITUTION:The devie consists of a photosensitive drum 2, an original platen 16, the indicating means 34, the shutter means 40, a pulse motor 50, etc. The indicating means 34 and the shutter means 40 are driven by the same driving source, i.e. the pulse motor 50. On the other hand, pulleys 48 are arranged on the upper side of shutter plates 41, 42 and an endless wire 49 is applied between the pulleys 48. One pulley 36 of the means 34 and one pulley 48 of the means 40 are coupled with the pulse motor 50 through decelerating gears 51, 52 respectively and the other pulley 48 of the means 40 is coupled with a pinion 45 through a decelerating gear 53, so that indicators 35 and the shutter plates 41-42 are simultaneously operated in accordance with the driving of the pulse motor 50. Consequently, the number of parts of the device can be reduced, remarkable cost down can be attained and high reliability can be obtained in the operation of the indicating means and the shutter means.
