摘要： In a drive device for an optical system of which scanning is carried out by means of a motor controlled for drive and stop by availability and unavailability of the power supply, any collision of the optical system moving by its inertia with its surrounding devices is not permitted, and furthermore even in restarting after the power supply is stopped during action of image forming, any collision of the optical system with its surrounding devices is not permitted. When the optical system is located in an area outside from a timing switch and a return switch, the motor is controlled for reversal braking so as to quickly reverse the direction of moving, thereby causing the motor to be usually stopped when the optical system returns to the safety area.

摘要： In an automatic density adjusting device in a copying machine, the width of variation in exposure intensity in relation to the change in a density correction value or magnification manually set is set to a large width if a document is dark, while being set to a small width if the document is light. Accordingly, exposure intensity corresponding to the density correction value or the magnification can be increased or decreased with respect to the light document and the dark document. Consequently, it is possible to always make the most suitable automatic density adjustment irrespective of whether the document is light or dark.
摘要翻译： 在复印机中的自动浓度调节装置中，如果文件较暗，则将曝光强度相对于手动设置的浓度校正值或倍率的变化的变化宽度设置为较大的宽度，同时设定为小 宽度如果文件较浅。 因此，相对于光文件和暗文件，可以增加或减少对应于浓度校正值或倍率的曝光强度。 因此，无论文件是浅还是暗，都可以始终进行最合适的自动浓度调节。

摘要： An optical system driving device has a motor which rotates constantly in one direction for providing rotary driving power. A regular rotation electromagnetic clutch is connected to the rotating motor for transmitting driving power to the optical system for reciprocal movement of the optical system in one direction. A reverse electromagnetic clutch connected to the rotor motor transmits driving power to the optical system for reciprocal movement thereof in the opposite direction. A control circuit is provided which receives a pulse signal for controlling either the regular rotation or the reverse electromagnetic clutch at the start of the regular rotation electromagnetic clutch to gradually increase the effective driving power provided to the optical system to move the optical system at the start of movement.
