Title: Method for driving optical shutter head for optical printer
Inventor: MATSUBARA KEN
IPC: G02F1/03
Filed: 1989-06-30
Abstract: PURPOSE:To eliminate the fluctuation in the quantity of transmitted light of the optical shutter head even if recording operations are repeatedly executed by executing a recording stage to perform the recording operation by selectively acting the electric field in a prescribed direction on the optical shutter head and a stage for recovery from fatigue by acting the electric field in the opposite direction on the shutter head between the recording stage and the ensuing recording stage. CONSTITUTION:A driver 23 selectively impresses a voltage V1 to respective electrodes 12 according to the latched image data when the image data is inputted to a 1st driving circuit 20. The electric field of the prescribed direction is formed between the electrodes 12 impressed with the positive voltage V1 and the electrodes 13, by which shutter elements 11 are turned on and light is transmitted. The electric field is not formed between the electrodes 12 on which the voltage V1 is not impressed and the electrode 13 and, therefore, the light is shut off. A transistor 32 turns on to impress the positive voltage V2 on the electrode 13 when the recording ends. The electric field of the direction opposite to the direction of the electric field during the recording period is then formed and the unnecessary charge of the photosensitive body is erased. The characteristics of the driving voltage-quantity of the transmitted light do not fluctuate and the stable exposing operation is executed in this way even if the recording operations are repeated.
