Title: Search tuner
Inventor: INOUE AKIO
IPC: H03J7/28
Filed: 1985-05-28
Abstract: PURPOSE:To prevent surely the influence of high frequency noise due to a limiter circuit and a malfunction due to noise at no signal by bringing a transistor (TR) to a saturation state at reception or at no signal so as to inactivate a limiter circuit. CONSTITUTION:In operating an automatic search start operation button, a sweep pulse from a sweep oscillator is applied to a programmable counter 14 and the count of the programmable counter 14 is changed sequentially. When the sweep frequency approaches the broadcast frequency and the carrier level reaches a prescribed level or above, TRs 2, 3 constituting the control circuit 25 are both biased to be turned on. Since the TR 1 constituting the limiter circuit is set to a proper bias state by resistors R2, R3, then the TR 1 acts like an amplifier circuit and its output amplitude is limited by the saturation level an the cut-off level of the TR 1.

Abstract: PURPOSE:To prevent misprint by providing a mode in which an image is transferred on a transfer body and a mode in which a toner image can be seen from the outside of a machine without transferring the image on the transfer body. CONSTITUTION:In the mode where the toner image is transferred on the transfer material, an electrostatic latent image is formed on a photosensitive drum 1 by turning on/off laser 3 according to image information transmitted from a computer.

When the toner image comes on the drum 1, the rotation of the drum 1 is stopped and the image is made to be seen through an acrylic window 13. Therefore, the image can be confirmed before it is printed out, thereby preventing the misprint.
