IPC: H03F3/16
Filed: 1984-02-15
Abstract: PURPOSE:To eliminate the influence of power source noises by providing a capacitor between the source and gate of a PMOS transistor constituting an inverter together with an NMOS transistor and a parallel circuit of a capacitor and resistance between the drain and gate of the PMOS transistor. CONSTITUTION:An inverter circuit is constituted by respectively connecting the drain and gate of a PMOS transistor (TR) 6 to the drain and gate of an NMOS TR7 and sources of the TRs 6 and 7 to a power supply terminal and earthing potential. A capacitor 5 is connected between the source and gate of the TR6 and another capacitor 8 is connected between the gate and drain of the TR6. An equivalent high resistance composed of NMOS TRs 10 and 11, whose gates are connected with each other, is connected in parallel with the capacitor 8. Moreover, the TRs 10 and 11 are connected in such a way that PN junction formed between the source and well electrode and drain and well electrode have a relation of forward bias and reverse bias to each other. In such a way inverted phase voltages of power source noises are generated and influences of noises can be eliminated.

Abstract: PURPOSE:To eliminate the occurrence of a static ghost image and at the same time keeping the linearity of a scanning locus, by securing a larger angle then a prescribed one between the divisor plane of the medium to be scanned and the scanning surface drawn by the scanning main beam. CONSTITUTION:The laser beam sent from the laser tube 10 is swept in the horizontal direction by a rotary mirror 16 via the 1st mirror 11, modulator 12, the 2nd mirror 13 and beam expander 14. This laser beam is then converged through the ftheta lens 17 and then scans the surface of the photoreceptor drum 23 via the 3rd mirror 18 and the 4th mirror 19. In this case, the angle theta is set larger than tan<-1> (d/2f) between the scanning surface (a) and the divisor plane of the drum 23 by controlling the mirror 19, where (f) is the focal length of the lens 17 and (d) is the incident beam diameter to the lens 17. As a result, the light (c) reflected on the drum 23 goes outside of the recording region to avoid the occurrence of a static ghost. On the other hand, the linearity can be kept for the scanning locus.
