Title: Cleaning device for rotary paper feed member in bi-surface copying machine
Inventor: TANABE TAKESHI
IPC: B65H3/06
Filed: 1983-05-04
Abstract: PURPOSE:To maintain the peripheral surface of a re-feed roller to be clean so that the lowering of friction coefficient of the roller is prevented, by making the re-feed roller and a separating sheet opposed together to rotate the re-feed roller so that the separating sheet cleans the roller. CONSTITUTION:A bi-surface copying machine comprises an intermediate tray 30, a paper feed device including a re-feed roller 27 which is contacted to a transfer medium 19 stored in the intermediate tray 30 and having its copied first surface and then feeds it, and a separating sheet 31 for separating the copied transfer medium 19. The one-surface copied transfer medium 19 passes the re-feed roller 27 which makes in contact with the separating sheet 31 to rotate by one rotation. With this arrangement, toner, paper dust, dirt, etc. which are adhered to the re-feed roller 27 are scraped off by the separating sheet 31 so that a friction coefficient on the roller surface of the re-feed roller 27 is prevented from lowering. In the next process the one surface-copied transfer medium is surely fed with good timing by the re-feed roller 27.

Title: Coordinate input unit
Inventor: OONUMA YASUHITO
IPC: G06F3/037
Filed: 1979-06-20
Abstract: PURPOSE: To obtain an inexpensive coordinate input unit of light pen control that is never influenced by external-light shadows, by detecting and processing at least two or more input signals while the 1st signal of a light pen is being input.  
     CONSTITUTION: With the operation switch of a light pen pushed, a switch signal from line 12 and a photo detection signal from line 11 are input to AND gate 1, the output of which sets FF2. The 2nd pulse signal from line 11 triggers monostable multivibrator 4, the operation time of which is set by the time constant of resistance R and capacitor C, and when the operation of monostable multivibrator 4 ends, line 15 is sensed. When no signal arrives from line 15, display data on a normal screen are considered to have been pointed out and FF6 is set to set coordinate values by the Q output of FF6. Since detected light lasts for a long time in case of external light, etc., the detection signal is sent out in sense operation by multivibrator 4 and FF6 is not set, so that no influence of afterglow will be exerted.

Title: Image information detecting method by photoelectric conversion element
Inventor: MIYASAKA TSUTOMU
IPC: G01J1/42
Filed: 1991-04-11
Abstract: PURPOSE:To extract a dynamic component only from image information by using a differential induction type photosensitive element as a photoelectric conversion element. CONSTITUTION:A differential induction type photoelectric conversion element, when the light on which the pattern of the light intensity is a rectangular wave is made incident, gives a positive response in a moment when the lights is inputted, when the incident light is a constant quantity, gives instantaneously 0 as a stationary output, and when the light is interrupted, gives a negative response in a moment. As the sensitive material suitable for the response, the sensitive chromoprotein is exemplified. The chromoprotein used preferably especially is bacteriorhodopsin. The photoelectric conversion element consists of a hydrophilic layer including 2 types of the electrode and the thin film and electrolyte of the bacteriorhodopsin sandwiched between them. The extraction of a dynamic image in the image using the element directly uses the above-mentioned differential response, and the change of the light quantity given by the incidence of the light information of the dynamic component is selectively caught in the shape of the current response. Thus, only the dynamic component can be selectively extracted from image information in the shape of the electric signal.
