Abstract: PURPOSE:To avoid the lowering of stability to the signal and to reduce the effect of the remote feed to be given to a power supply, by securing the actuation of an auxiliary repeater when the using repeater is taken out and after connecting the auxiliary repeater in parallel to the using repeater. CONSTITUTION:A switch 2 and an auxiliary repeater 3 are connected to a using repeater 1 at the points A and B, respectively. In this case, a diode switch 9 is adversely biased by a battery 10c of a power supply circuit 10, and both the feed system and the signal system receive no effect owing to the connection of the switch 2. When the repeater is taken out, the remote feed current makes the switch 9 conduct and is divided to flow to a photocoupler 13 and a voltage control circuit 14. These currents flow to a repeater at the rear stage through a Zener diode 12, an auxiliary repeater 3 and a voltage control circuit 11. In this case, the transistor side of the photocoupler 13 is saturated and the voltage applied across the diode 12 is instantaneous lowered down to the value of the saturated voltage of the transistor.

Abstract: PURPOSE:To eliminate astigmatism on an image carrier without exerting any influence upon the relation between a light source and a collimator lens by enabling the distance between a scanning means and the collimator lens to be adjusted. CONSTITUTION:A beam from a semiconductor laser array 1 is emitted from light emission points 11a and 11b and projected on the collimator lens 12. While the interval between the lens 12 and laser 11 is held constant, they are moved forth and back on the optical axis to absorb the deviation of the intersection of main light beams 12a and 12b from a polygonal mirror 13 due to common differences in the angle between the points 11a and 11b and the interval. The main light beams 12a and 12b are passed through a cylindrical lens 21 and reflected and scanned on the reflecting surface 13 of a mirror 13 as the scanning means to form two spots on a photosensitive body drum 1 through an ftheta lens 14. Two scanning lines 20a and 20b are therefore formed by one scan through the rotation of the mirror 13.
