Abstract: PURPOSE:To stably feed a sheet in a simple structure by urging a feed roller disposed on one end of an arm toward a sheet, and opening and closing a brake to control a wire urging a hopper according to a signal of an arm sensor disposed on the other end thereof. CONSTITUTION:As feed rollers 4 and 6 are driven to feed stacked sheets 3 sheet by sheet from the uppermost, the height of the sheets 3 decreases, and the displacement of an arm 7 is detected by an arm sensor 9. When the displacement reaches to a certain limit, the arm sensor 9 is turned off, and an OFF signal is input to a control portion 10. Whereupon, an OFF signal is sent to a brake 15 to release the restrain on a shaft 14, so that a hopper 1 is gradually lifted up by action of a hopper spring 13 and a dash pot 16 to push up the feed roller 4 and switch on the arm sensor 9 again. The ON signal is transmitted to the brake 15 through the control portion 10, so that the brake 15 is again turned on to restrain the shaft 14 again and stop lifting the hopper 1. Such operation is repeated to stably feed a sheet.

Filed: 1985-02-28
Abstract: PURPOSE:To facilitate the evaluation of a disc and the disc production process by allowing the turning position of a periodic signal, which is recorded on the disc once for one rotation of a turntable, to coincide with a reference turning position of the turntable. CONSTITUTION:When detecting an object 14b to be detected, a turning position detector 14a of a recorder generates a detection signal. If the object 14b to be detected is attached to a revolving shaft 5 in accordance with the reference turning position of the turntable, the turning position detector 14a generates the detection signal in the reference turning position of the turntable each time when the turntable is rotated once. The phase of this detection signal and that of the periodic signal in the information signal are compared with each other by a phase comparator A15; and when a rotation driving device 3 is controlled by a turntable control circuit 12 so that the output error signal is zero, the periodic signal 9a is recorded in parallel with the reference turning position of the turntable. Thus, the recording position on the disc is used as a mark to evaluate the disc easily, and the disc production process is evaluated easily.

Filed: 1990-02-20
Abstract: PURPOSE:To achieve reduction of demand by increasing switching speed by a method wherein a minimum intensity of laser beam which can be detected with a positional detection means is made not more than a maximum intensity of laser beam which can not be recorded on a recording medium. CONSTITUTION:When an image signal synchronizes with a standard positional signal, and output of a RS flip-flop 22 is at a higher level than an image signal control circuit, a modulator drive circuit 26 outputs drive voltage of an optical modulator 2 corresponding to a light quantity level which performs recording on a recording medium 8 to the optical modulator 2 according to voltage of a modulating signal input terminal. When the output is at a low level, the modulator drive circuit 26 outputs drive voltage to the optical modulator 2 corresponding to a bias light quantity level incapable of recording on the recording medium 8 to the optical modulator 2 according to voltage of the modulating signal input terminal. Generally the recording medium 8 is not exposed to light when the intensity of laser beam is not more than a certain threshold value. If a detectable minimum intensity of laser beam of a positional sensor 9 is made not more than a threshold value of the recording medium 8, though laser beam at a bias light quantity level not less than the detection minimum light quantity is radiated at the threshold value or under, the recording medium 8 is not exposed to light. However, the position becomes capable of being detected.
