IPC: H04N1/19
Filed: 1995-11-11
Abstract: PROBLEM TO BE SOLVED: To prevent the quality deterioration of a formed image that is caused by the foreign matters attached on an original board. SOLUTION: The original reader is used to an image forming device and optically reads an original 1 put on an original board 11. The foreign matters attached on a contact glass 2 of the reader are read by a command of a control part 30 in a prescribed section of the original 1 which is set before the image of the original 1 is read. When the black data which are continuous in the prescribed length or more are detected out of an original image set at the same main scanning position as the image that is read in the preceding prescribed section of the original 1 when the original image is formed, the black data are canceled at an image processing part 36. Thus it is possible to prevent the quality deterioration of a copy image of the original image that is caused by the black lines which are formed in the main scanning direction by the foreign matters attached on the glass 2 of the board 11.

IPC: H02H9/02
Filed: 1988-12-19
Abstract: PURPOSE:To obtain a light-receiving element protection circuit for protecting a light-receiving element from an excessive current caused by an excessive light input by monitoring an electric current flowing through a light-receiving element to control a supply voltage outputted by a variable voltage power supply so that the electric current does not exceed a specified value. CONSTITUTION:An amplifier 40 amplifies a signal voltage outputted by a light- receiving element 10. An automatic gain control circuit 41 detects an output voltage of said amplifier 40 to control a supply voltage outputted by a DC-DC converter 30 to lower the voltage besides controlling the amplification factor of said amplifier 40 so that said factor is included in the range at a specified level. A voltage across the ends of a current-sensing resistor 23 is amplified by a differential amplifier 21 and compared with a reference voltage at a comparator 22. Thus, because control is immediately performed when an electric current higher than a specified value flows through the light-receiving element 10, an excessive current can be prevented from flowing through the light- receiving element 10.
