Inventor: TANIGUCHI HIDEO
IPC: B41J2/45
Filed: 1986-09-05
Abstract: PURPOSE:To prevent the generation of an error at the time of forming information on a photosensitive body even if optical outputs from the light emitting body have variance by determining the transmissivity of parts corresponding to respective light emitting parts on a photographing sensitive material and sharply attenuating light radiated from a light emitting part having large optical output so that the quantity of light radiated to the photosensitive body is uniformly corrected.

An image 14'b on a corresponding part 14'a corresponding to a light emitting element 4b having a large optical output is thick and its transmissivity is reduced inversely proportional to the optical output. On the other hand, an image 14'b of the corresponding part 14'a corresponding to the light emitting element 4b having a small optical output is thin and its transmissivity is relatively increased. Consequently, the quantity of light projected from respective light emitting element 4b and converged to the outer periphery 15a through the corresponding part 14'a is uniformed and dots constituting an electrostatic latent image are uniformly formed on the outer periphery 15a, so that the generation of an error can be previously prevented at the time of forming information on the photosensitive body.

Abstract: PURPOSE:To attain quick data collection, by sending a polling signal addressed to the succeeding terminal equipment from a terminal equipment not awaiting the transmission in applying polling to said terminal so as to allow a control station to eliminate the need for the polling signal addressed to the succeeding terminal equipment. CONSTITUTION:A host CPU 10 awaits a data after an ENQ sequence transmission and discriminates whether or not the data is the ENQ data or the transmission data in receiving any data. Assuming that a terminal equipment 141 does not send a data but sends the ENQ sequence, the CPU 10 discriminates the absence of data in the terminal equipment 141, a terminal equipment designation value SA in the received ENQ sequence is revised into N+1 and the data reception from a terminal equipment 142 corresponding to SA=02 is awaited. When the terminal equipment 142 receiving the ENQ sequence sends a data to a line 13, the CPU 10 discriminates the data reception and recognizes/processes the received data as the transmission data of the terminal equipment 142 corresponding to SA=02. Then the polling signal addressed to the next terminal equipment is not transmitted.
