Title: Copying device
Inventor: ADACHI HIDEKI
IPC: G03B27/62
Filed: 1984-05-15
Abstract: PURPOSE:To prevent defective copies by displaying how an original is shifted from a normal position by an original coordinate detector which detects the position of the original placed on an original platen. CONSTITUTION:The surface of an original pressing plate 133 in the side facing an original platen 132 is painted black, and the reflected optical image from an original 131 is formed through a lens 138, and the variable density of the picture is read. The output from a CCD sensor 140 is amplified by an amplifier 141 and is converted to a digital value by an A/D converter 142, and this digital value is compared with a standard value, and the variance due to the quantity of light and picture elements is corrected by a correcting circuit 143, and the picture is binarized to white or black by a binarization circuit 144. When the original 131 is placed on the original platen 132, the reflected optical image is read in lines along the Y axis by picture elements of the CCD sensor 140, and scanning is performed in the X axis direction, and coordinates of the position of the first change from black to white and the position of the last change from white to black on every line in the Y axis direction are obtained in accordance with the binary signal. A CPU performs various operations on a basis of these position detection signals to operate a controller for correct copies.

Title: Binary coding device of picture signal
Inventor: KOUTOU HAJIME
IPC: H04N1/403
Filed: 1982-06-02
Abstract: PURPOSE:To obtain a binary coded output faithful to information of an original, by forming a comparing signal with a picture signal having deteriorated contrast. CONSTITUTION:Irregularly reflected light from the original 4 is received at an image sensor 9 via an optical system and photoelectric converted. On the other hand the reflected light reflected on a half mirror 7 partly is reflected on a full reflecting mirror 8 and received on an image sensor 10. Since a lens 6 is adjusted so as to be focused on a photodetecting plane of the sensor 9, the reflected light is not focused on the photodetecting plane of the sensor 10. An output picture photoelectric converted at the sensor 9 is a continuous video signal at a sample holding circuit 11 and inputted to a plus terminal of a comparator 15. Further, the picture signal photoelectric converted at the sensor 10 is superimposed with a DC voltage E0 through a sample holding circuit 12 and inputted to a minus terminal of the comparator 15. A waveform of a reference signal input 14 of this comparator 15 is deteriorated in contrast more than the picture signal. The comparator 15 binary-codes the picture signal with this voltage taken as a threshold value and a binary coded signal faithful to the picture signal is obtained at a terminal 16.

Filed: 1980-07-15
Abstract: PURPOSE:To unnecessitate the use of a current transformer for current detection by a method wherein the secondary frequency to be induced on the secondary circuit of the motor is converted to the control timing signal for acceleration of the motor. CONSTITUTION:The secondary frequency detecting section 51 picks up the voltage, at an optional tap of a secondery resistor 62, having the frequency in proportion to the slip of the motor, which is generated on the secondary side of a wound-rotor type induction motor 13. A frequency discriminating section 52 discriminates the frequency of the voltage supplied by the secondary frequency detecting section 51. An acceleration timing setting section 53 compares the signal inputted from the frequency discriminating section 52 with the optional set signal an the results are outputted as the driving signal of short-circuit contacting devices 55-58 on the secondary resistors 59-62. Through these procedures, the current transformer can be unnecessitated.
