Filed: 1988-06-01
Abstract: PURPOSE:To reduce power consumption in a circuit enabling drive on rectangular waves by a method wherein an inductance element is connected across driving terminals, a first switching circuit is provided between a driving voltage source and a driving terminal, and a second switching circuit is inserted in series with the inductance element. CONSTITUTION:Between a charge-coupled device (CCD) driving terminal and a driving voltage source, a first switching circuit is inserted and, in series with an inductance element arranged between driving terminals or between a driving terminal and a semiconductor substrate, a second switching circuit is inserted. The rise and fall of the driving terminal voltage is effected on a low voltage by utilizing LC resonance and, after a change in the terminal voltage, the terminals are connected to the driving voltage source for the sustenance of a constant voltage. Using this design, an approximately rectangular driving voltage may be applied to the CCD driving terminals. With the inversion of the driving voltage being accomplished on the strength of LC oscillation, the CCD driving power may be kept low.

Filed: 1983-07-22
Abstract: PURPOSE:To detect the size of any kind of original by providing an encoder which generates the proper number of pulses corresponding to the extent of the rotation of a roll. CONSTITUTION:An original is sent by a conveyor roll 13 toward a platen 2 and stopped temporarily at a gate 12. Then the original is sent onto the platen glass 2 by an original conveyor belt 11 by elevating the gate 12 with a signal from a controler, and stopped at a specific position. while the original contacts with the roll 14, the roll 14 rotates until the original passes through the roll 14. The rotation of the roll 14 is transmitted to the encoder 16 through a pulley 15. Its extent of rotation is transduced into the number of pulses by a photointerrupter 17. This number of pulses is counted to know the overall length of the original because the length of the origianal per pulse is known previously.
