IPC: H03K19/0952
Filed: 1981-12-11
Abstract: PURPOSE:To operate a titled circuit with a single power supply, by inserting a diode or a resistor between a common connecting point of sources of normally- on type Schottky gate FETs as a plurality of NOR or NAND gates and ground potential, and connecting the gates via a level shift circuit. CONSTITUTION:A constant current is supplied to Schottky diodes D21-D24 with normally-on type Schottky gate FETs Q41-Q44 and a shift voltage (0.8V) is obtained. A Schottky diode D31 is used as a constant voltage source making the source potential at common connecting point of the FETs more positive than the ground potential. Since the current flowing to the diode D31 is the subtraction of the total sum of the current sources Q41-Q44 from the total sum of the current of current source loads Q31-Q34, it is always constant and the circuit acts as a constant voltage source. As a result, the logical amplitude is 1.6V.

IPC: G03G15/00
Filed: 1989-07-31
Abstract: PURPOSE:To simplify processing for forming an image after cancelling interruption by deciding the copying area of an original placing plate in accordance with a selected mode. CONSTITUTION:At the time of interruption, the key 46 of a panel 40 is used to select an ordinary interruption mode for processing a new original and a special interruption mode for processing a new original in a state where an original before interruption is placed. In the case of the special mode, an area deciding means 50, for example, specifies the latter half of the original placing plate and decides the area for interruption by using the designation key 48 or the ten keys of the panel 40. According to the decision of the means 50, optical systems 10, 11, 13, 16 and 17, a paper feeding system 21 and a photosensitive drum 2 are controlled by following the procedure of ordinary interruption copying when an ordinary home position is the area for interruption. When the latter half of the original placing plate is the area for interruption, the optical systems and the photosensitive drum are ordinarily controlled but the same action as in a page consecutive copying mode is performed corresponding to timing when the optical system 10 comes to the latter half of the placing plate. Thus, the processing for forming the image after interruption is simplified.
