Abstract: PURPOSE:To miniaturize a device main body, to simplify an electric circuit of a device and to reduce cost concerning the cassette control device of a copying machine. CONSTITUTION:When a motor 21 rotates clockwise seen from the right side of a drawing 1, its rotation is transmitted to a clutch 25 by a pulley 22, a belt 23 and a pulley 24, and one shaft of the clutch 25 rotates clockwise as well as the motor 21. Clockwise rotation of the one shaft of the clutch 25 is transmitted to the other shaft. When the other shaft rotates, a coupling 28 rotates, and a coupling 29 rotates in a first paper feeding cassette seen from the left side of the drawing 1. Consequently, a lever 71 rotates, a base plate is lifted upward by the head end part of the lever 71, a sheet is made contact with a paper feeding roller and is put in the state to be fed. When the motor 21 rotates counterclockwise, a lever 72 rotates in a second paper feeding cassette, the base plate is lifted upward by the head end part of the lever 72, the sheet is made contact with the paper feeding roller and is put in the state to be fed.

Title: Semiconductor memory
Inventor: WATANABE KATSUMI
IPC: G11C11/41
Filed: 1988-06-23
Abstract: PURPOSE:To omit a control circuit and also to attain an action accordant with the actual value of the delay time by setting a memory cell on an extended memory cell selection line and controlling the output of a data line received from said memory cell with the selection signal of a chip selection signal line. CONSTITUTION:A selection response cell 112 of the same type as a memory cell is connected onto an extended line of a memory cell array 106 for a memory selection line led from an address decoding buffer 107. Then a data line is connected to a response signal gate 113 and a chip selection signal line 103 is inputted as a control line. Then one of memory cells in the cell 112 is selected at the point of time when the array 106 is selected. The data received from the cell 112 is outputted to a response signal output line 114 as a selection response signal of a memory cell at the input of a chip selection signal. Thus the optimum delay time is secured without using any control circuit by sending the selection response signal back to a CPU as it is.

IPC: G03G15/23
Filed: 1984-07-27
Abstract: PURPOSE:To copy an original of size larger than original platen glass and an original of normal size by varying process conditions according to original size. CONSTITUTION:When the large-sized original is copied, the line speed of a photosensitive drum 10 is equalized to the line speed of a fixing device 20 and the feed speed of the original is also made equal to the line speed of the photosensitive drum 10. The line speed of the fixing device 20 is the same with the original of normal size, but the line speed of the photosensitive drum 10 and the feed speed of the original decrease. Then, the discharging current of an electrostatic charging electrode 11 is lowered as compared with the copying of the original of normal size to lower the voltage of a light source for exposure. Discharging currents of a transfer electrode 17 and a separation electrode 18 are made equal to each other, but the DC bias applied to the separation electrode 18 so as to lower the potential of the photosensitive drum 10 to zero is made lower than that of the normal-size original. Consequently, a both-sided original is copied.

Title: Polling transmission system
Inventor: NAITOU HITOSHI
IPC: H04L12/403
Filed: 1982-09-08
Abstract: PURPOSE:To detect automatically the restoration of a slave station when system down is occured, by transmitting a common polling in succession to a normal polling including an individual address. CONSTITUTION:A master station performs initialize processing at the operation start (ST1). The normal polling including an individual address is transmitted sequentially to each slave station (ST2). A slave station in no response is separated from the normal polling as a down-terminal (ST7) and sets a common polling flag (ST8). The master station transmits the common polling in succession to the normal polling (ST8). The master station transmits the common polling in succession to the normal polling. When the separated slave station restores from system-down and receives the common polling, the restoring response is performed for the master station (ST11). The master station resets a down- flag of a station desiring restoration for processing restoration (ST14). Then, the master station detects automatically the restoration of the slave station, no manual operation is required for the restoration processing and the reliability of the system is improved.
