Title: Image forming device
Inventor: MAKITA KATSUHIKO
IPC: G03G15/047
Filed: 1987-06-26
Abstract: PURPOSE:To prevent the occurrence of omission of necessary information on the boundary part of a specified area according to the content of an original being synthesized at the time of generating a synthesized copy by slightly lowering variable power rate of trimming than that of masking. CONSTITUTION:Corresponding light sources outside a specified area 2a including aligned light sources comprising an eraser 1, which correspond to image of 'ka ki ku ke ko' is turned on at the time of trimming as marks O show and the light source in the specified area is turned on in masking as marks  show. The variable power rate which exposes an original onto a photosensitive body at the time of trimming is slightly lowered with a proper power rate than the variable power rate in masking. As a result, as for a trimming image, a range which is bigger than the specified area is reduced and reproduced and letters, 'o ka ki ku ke ko sa', though they get a little smaller, are reproduced on the synthesized copy 4. Thus the omission of the necessary information is prevented that is caused by the disappearance of the image on the boundary part of the specified area when the image is synthesized.

Abstract: PURPOSE:To confirm the coincidence of contents of microprogram P of plural controllers sharing a device to be controlled in a short time and to prevent the fault caused by the disturbance of the control information, by performing comparison of the edition number information among those microprograms muP. CONSTITUTION:The edition number information of the muP are read out of a microprogram memory part 14 and the systems A and B of an information memory part 15 are written into addresses 0 and 1 respectively when the power supply is applied to a microprocessor 13 of the system A for initialization. Then the output of an FF 16 of the system B is checked and decided as 0. Thus an FF 16 of the system A is set at 1 and the operation is started. When the power supply is applied to the system B for initialization, the same operation as that of the system A is carried out. A processor 13 of the system B compares the edition number information on the P of the system A stored in an address 0 of the part 15 of the system A with the maximum address of the part 14 of the system B or the edition number information on the address 1 of the part 15. Then the coincidence is obtained from this comparison, the contents of the part 15 of the system A are copied to the part 15 of the system B. Then the operation is started after setting the FF 16 at 1. When no coincidence is obtained, the processor 13 of the system B erites the fault information to the specific areas of both parts 15 to stop the operation.
