Title: Information recorder-reproducer
Inventor: TSUNODA YOSHINORI
IPC: G11B17/22
Filed: 1992-03-03
Abstract: PURPOSE:To enable execution of dubbing by one apparatus using one optical pickup and to enable simultaneous reproduction or recording of a plurality of disks. CONSTITUTION:After information recorded in compression in a first disk is reproduced by an optical pickup 117 and written temporarily in a memory, the optical pickup 117 moves to a second disk and records therein the information read out from the memory, and this operation is repeated. The disks are held in first and second cartridges 103 and 104 and recording and reproduction are conducted only in opening parts 110a and 111a. Therefore loading is conducted while the first and second cartridges 103 and 104 are rotated by first and second swing arms 203 and 205 respectively so as to make the respective opening parts thereof opposed to each other. The optical pickup 117 fitted to an arm 211 swings between the two cartridges and executes recording and reproducing operations for each disk.

Title: Photoelectric transfer device
Inventor: SHINOHARA MASATO
IPC: H04N5/378
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To output a correct signal in a short time after the power of a photoelectric transfer device is turned on by injecting the same type of charge carrier as the one generated by casting light. SOLUTION: Immediately after the power of a photoelectric transfer device having pixels is turned on, the potential of a terminal 7 is increased much higher than the reference voltage at a terminal 4 to turn a diode 6 into a forward biased state and a photo transistor 1 into an on state and thereafter the potential of the terminal 7 is lowered. The charge carrier which is the same type as the one generated by light injected into the photo transistor of a photoelectric transfer element from the diode 6 is immediately discharged by the forward bias current of a diode 2, and thereby the base of the photo transistor 1 reaches a stationary state wherein the base current is equal to the current generated by light.  By injecting the charge carrier into the pixels, the instability of the output when the power of the photoelectric transfer device is turned on can be removed in a short time to obtain the correct output.
