Title: Level suppressing circuit
Inventor: IMAI KATSUMI
IPC: H03G11/04
Filed: 1997-09-30
Abstract: PROBLEM TO BE SOLVED: To suppress the level of an input signal while a natural waveform is kept as it is by rectifying the full waves of two output signals from a differential amplifier, comparing desired reference voltage with the output signal level of a full wave rectifier circuit and changing the gain of the differential amplifier in accordance with the output signal. SOLUTION: The gain variable first differential amplifier 10 amplifies an input signal and generates two output signals in a relation where phases are inverted. One output signal from the first differential amplifier 10 is applied to one input terminal in the second differential amplifier 11 and the other output signal of the first differential amplifier 10 to the other input terminal. The full wave rectifier circuit 12 rectifies the full wave of the two output signals from the first differential amplifier 10. A comparator 13 compares reference voltage Vref decided in accordance with the dynamic range of the output signal of the first differential amplifier 10 with the output signal level of the full wave rectifier circuit 12. The gain of the differential amplifier 10 is changed in accordance with the output signal of the comparator 13 and the level of the input signal is suppressed.

Abstract: PURPOSE:To lighten rewinding load and to prevent the damage of the coating surface of a light receiving sheet by providing a home position setting means setting a first home position when an image is formed and a second home position when the sheet is rewound. CONSTITUTION:When the image is formed, the light receiving sheet 103 which has been wound around a supplying shaft is carried from the home position H1 by a buffer roller 104 and pulled out, and taken up to a taking-up shaft 105. When the sheet is rewound, the light receiving sheet 103 which has been taken up to the taking-up shaft 105 is rewound by the supplying shaft 102 through the buffer roller 104. At this time, the buffer roller 104 is carried to the home position H2 by the home position setting means 101 and comes to a position where the light receiving sheet 103 is allowed to pass in a straight line. Therefore, the coating surface of the light receiving sheet 103 is not brought into contact and its path is made simple. Thus, the rewinding load is lightened and the surface of the light receiving sheet can be prevented from flawing.
