Title: Copying device
Inventor: SAWAKI AKIRA
IPC: G03G15/22
Filed: 1985-04-24
Abstract: PURPOSE:To prevent copies from difficult observation at the left picture part of a file by forming a margin part on copying paper on the opposite side to an additional information display part and using the margin part as a binding margin e.g. CONSTITUTION:The title device is provided with function keys 23, a keyboard interface 24, a ocntrol circuit 25, a light source driving circuit 26, a light source 27 for erasing electric charge a photosensitive drum 28, etc. The size of copying paper is specified by ten-key 22 and the key 23. The margin width in each size of copying paper is previously stored in the circuit 25. When confirming the size of the copying paper by receiving a code signal from the interface 24, the circuit 25 reads out the margin width corresponding to the size from its storage area and sends a control signal to the circuit 26. The circuit 26 drives the light source 27 in accordance with the signal and illuminates only a portion from the left end to the margin width to erase an electric charge of the drum 28. Even if the area of the margin width of which electric charge is erased is exposed by exposing information, no electrostatic latent image is formed on the area. Thereby, a margin is formed on the left side of the exposed and thermally fixed copying paper.

Abstract: PURPOSE:To simplify the adjustment of a driving current of plural tracks, and to make a noise low, by preparing simultaneously an MR head having scarcely variations by use of a thin film forming technique, obtaining a reproducing amplifier by utilizing it, and using plural amplifiers for applying contant DC voltage to its input. CONSTITUTION:In case when the gain of an open loop of a differential amplifying circuit 12 is sufficiently higher than the gain of a closed loop, a current is supplied to an MR head so that voltage of a connecting point of a resistance 26 and MR heads 10-1, 10-n becomes equal to voltage of a connecting point of a resistance 27 and 28 of a driving voltage circuit 29. Voltage being proportional to a resistance variation of the MR head is obtained across the resistance 26. MR head driving currents of each track can be adjusted simultaneously by only varying the output voltage of the driving voltage circuit 29 by a variable resistance 28. As for a noise source, there are only a head noise and a noise of the amplifying circuit 12, and by adoptig a low noise transistor, a low noise can be realized. In this way, the head driving current can be adjusted simultaneously, and the operability is improved remarkably.
