Title: Multi-color image recorder
Inventor: SERIZAWA YOJI
IPC: B41J2/44
Filed: 1987-02-16
Abstract: PURPOSE:To improve the balance of picture quality among respective color images by variably controlling the spot size of two kinds of laser beams for forming respective electrostatic latent images. CONSTITUTION:Since one reflecting mirror 4 of a multi-color image recorder is constituted so as to be moved in the advancing direction of a 2nd color laser beam 6 and the diameter of a laser beam spot projected on a photosensitive drum 1 is changed in accordance with the moving distance, the spot size of the formed electrostatic latent image can be also changed. Namely, the spot size of the electrostatic latent image formed on the surface of the drum 1 is changed like (a), (b) and (c) in accordance with the positions of reflection mirrors 4, 4', 4''. Thereby, the adhesive quantity of toner to each electrostatic latent image is changed in accordance with the difference of each toner component, so that the width of respective printing lines can be uniformized.

Filed: 1988-02-15
Abstract: PURPOSE:To accurately follow up the response of an output signal for an input signal to a fast switching operation by constituting the title circuit of an NPN type transistor small in capacity being attached on a base area such as between a base and a collector and between the base and the ground. CONSTITUTION:When a signal of L is inputted to an input terminal 12 and and a signal of H to an input terminal 13, the emitter current I1 of a transistor(TR)1 is decreased, and the emitter current I2 of a TR2 is increased. The current I1 goes to the collector current I2 of a TR4 by the current mirrors of the TRs 3 and 4. Then, a current difference I2-I1 goes to the base current of a TRs, thereby, the TR5 is turned ON. Adversely, when the signal of M is inputted to the terminal 12 and the signal of L to the terminal 13, the I1 of the TR1 is increased, and the I2 of the TR2 is decreased. Then, the base current (I2-I2) of the TR5 disappears, thereby, the TR5 is turned OFF. By selecting values in which no saturation of TRs 6 and 7 are generated as the current values of the constant current source of a differential circuit consisting of the TRs 6 and 7 and resistors 8 and 9 by the switching operation, and eliminating a saturation area to decelerate the operating speed of the TR, it is possible to follow up the fast switching operation.
