Title: Image sensor reader
Inventor: SAKAI MASAKI
IPC: H04N1/19
Filed: 1986-02-10
Abstract: PURPOSE:To effectively correct a picture element signal due to temperature change in an environment having a large temperature change by holding a dummy signal voltage of a storage type image sensor. CONSTITUTION:A signal V22 is outputted from the storage type image sensor 21 by using a drive signal phi21 outputted from a timing control section 28. The signal V21 is amplified by a DC amplifier 22 to obtain a signal V22. A switch 24 is closed by a signal phi22 from the timing control section 28 with a dummy signal and a capacitor 23 is charged depending on the potential difference between the voltage V22 and a reference voltage Vr of the reference voltage source 25. The capacitance of the capacitor 23 is selected as a value holding the voltage over one scanning time of the storage image sensor 21. At the time of the picture element signal is outputted, the switch 24 is opened and the output voltage V23 of the capacitor 23 has a value being the subtraction of the voltage stored in the capacitor 23 from the input voltage V22. Thus, the change in the picture element signal due to temperature change is corrected.

Abstract: PURPOSE:To enable accurate speed control with a simple constitution, by amplifying the variance detection signal of the photosensitive drum drive speed in response to the speed ratio and adding it to the lens scan drive control reference voltage corresponding to the speed ratio. CONSTITUTION:The speed of the photosensitive drum drive section is detected at a speed detector 28, and the signal in response to the variance from a given speed is produced via the frequency-voltage conversion circuit 30 and level shift circuit 32, and it is amplified at the amplifier 33 in which the amplification factor is changed according to the set speed range via the magnification set circuit 37. This signal is added to the reference voltage in response to the set speed ratio output at the reference voltage set circuit 34, and it is compared with the detected speed signal of the lens scan drive linear motor 41 outputted at the 2nd frequency-voltage conversion circuit 31 and fed as the set voltage to the comparator 38 in feedback control of the motor 41. Thus, the speed detection of the 1st drive section such as photosensitive drum is not required with high resolution and accurate speed control even at speed change can be made with a simple constitution.

Title: Clock circuit
Inventor: KACHI YOSHIO
IPC: H03K5/15
Filed: 1982-02-22
Abstract: PURPOSE:To obtain plural clock signals being the same period as a clock signal and having different phases, by combining a delay circuit with a switch controlled with the clock signal. CONSTITUTION:Complementary MOS transfer gates 1-4 are controlled with clock signals phi1 and phi2, and the delay circuit 5 produces a phase difference required between the clock signals phi1 and phi2. When a clock terminal CK is a low potential, the siwtches 1, 4 are conductive and switches 2, 3 are nonconductive. When the terminal CK changes from a low to a high potential, the switches 2, 3 are conductive and the switches 1, 4 are nonconductive and the signal phi2 changes with a delay from the signal phi1. When the terminal CK changes from a high to a low potential, the state is restored to the initial state, the switches 1, 4 are conductive and the switches 2, 3 are nonconductive. Thus, plural clock signals being the same period as the clock signal and having different phases are obtained without using an FF.
