Title: New line detecting method for optical character reader
Inventor: YAMAGUCHI MIKIO
IPC: G06K9/20
Filed: 1987-06-05
Abstract: PURPOSE:To accurately detect line replacement by allowing a line appearance side detecting means to detect whether a line which already enters a visual field or a new line enters the visual field again at a position in the visual field of the line. CONSTITUTION:When a scanner 1 is held in a hand and an original 3 is scanned, an image of a line (a) read by the scanner 6 is converted by a controlled value binarization circuit 7 into a binary signal, which is recognized by each character recognizing means 8 and inputted to a comparator 12 through a format check part 9. When the original 3 is scanned for a 1st time, a last-time register 1 is already initialized, so a signal NEW is outputted and the recognition results are outputted through a control part 13. The recognition result of the line (a) is stored in a register A. When the scanner 1 is moved down, the line (a) disappear from the visual field upward. A line disappearance detecting means 16 detects the disappearance of the line (a) from the upper end from the output of a line position detecting means 15. When the scanner 1 is further moved down, a line (b) enters the visual field and a means 7 detects that. A decision means 18 clears the register 11 through an OR gate 19 and the measurement result of the line (b), on the other hand, is inputted to the comparator 12 and outputted from the control part 13.

Title: Toner cartridge
Inventor: MURAZAKI HIROSHI
IPC: G03G15/08
Filed: 1985-06-27
Abstract: PURPOSE:To obviate the out flow of a toner from a toner cartridge and the uncomfortable feel to a user when the cartridge is mounted to a copying machine and to eliminate the need for a laborious operation to open an outflow port by hermetically sealing the toner outflow part by a toner supply roller, blade plate and sealing member. CONSTITUTION:The blade 46 is attached to the upper part of an aperture 48 so as to project toward the inside of the toner cartridge 4 and contacts with the surface of the toner supply roller 45 to scrape off the excess toner conveyed by the roller 45. The sealing member 47, attached to the lower part of the aperture 48, contacts with the roller 45 under light pressure along the rotating direction of the roller to prevent the outflow of the toner from the inside of a body 41. Since the aperture 48 of the body 41 is hermetically sealed by the roller 45, the blade 46 and the member 47, the outflow of the toner contained in the body 41 is obviated. The lower part of the toner cartridge body 41 is so shaped as to exactly contact tightly with the receiving base 12 of a developing device 3 so as to prevent the outflow of a developer.

IPC: B65G27/32
Filed: 1977-11-26
Abstract: PURPOSE: To simplify the structure by using a commercial-frequency three-phase A. C. power supply sources as a means of setting up phase differences.  
     CONSTITUTION: Commerical-frequency three-phase A. C. power supply sources R, S. T are connected to horizontal oscillation electromagnet 4 and vertical oscillation electromagnet 7 via power supply switch 8, and at the same time, amplitude- adjusting, control-electrode-fitted semiconductor elements 9 and 10 are inserted into R-phase and T-phase lines. By this, when control-electrode-fitted semiconductor elements 9 and 10 are ignited when the voltage of R-phase and T-phase lines is positive, the power supply voltages of electromagnets 4 and 7 are added with R--S- phase and T--S-phase voltages. Then, the phase difference between horizontal and vertical direction oscillations becomes 60° and sufficient elliptical oscillation can be obtained. Further, by adjusting the ignition phase angle of control-electrode-fitted semiconductor elements 9 and 10, the magnitudes of the power supply voltages of electromagnets can be changed and thereby the amplitude of the vertical direction oscillation and that of the horizontal direction oscillation can be adjusted independently.

Abstract: PURPOSE:To provide a high-accuracy pattern drawing by providing a rate multiplier counter so that an output signal in wavelength unit corresponding to the movement of a stage can be made to a high-approximation of the desired meter unit output. CONSTITUTION:A laser beam from the laser generator 13 passes through the interferometers 15a, 15b and impinges on the corresponding plane mirros 12a, 12b. When the stage 11 moves in the X direction, a Doppler effect occurs to the reflecting beam, which is received by the interferometer 15a and given to the pulse comparator 17a. The comparator 17a uses the laser from the generator 13 as a reference signal and, by bearing this signal and the measuring signal, generates pulses in the unit of wavelength. The output pulses are counted by the multiplier counter 18 and generated as the output pulses in the unit of meter in response to the preset rate data. The output signal is given to the electron beam drawing control system to perform a pattern drawing on the tip of the stage 11.
