Abstract: PURPOSE:To drastically reduce the number of wires led to the robot main body so as to decrease the failure rate by arranging almost all components of a controller onto the robot main body and arranging only the components, which are necessary for an operator to directly operate, onto the control panel or a teaching device. CONSTITUTION:Only the switches or the like of a controller, which are directly related to the operator's command operation, are placed intensively on a control panel 4. In addition, the remaining components of the controller are arranged in the base part 13 of the robot main body 1 as the controller unit 14. As a result, the electrical wires existing between the robot main body 1 and the operation panel 4 are limited to signal conductors such as switches, which are directly operated by the operator. Therefore, the number of cables situated around the robot main body 1 can drastically be reduced. As a result, the frequency of troubles such as disconnection can be lessened, while the wiring cost can be reduced.

Abstract: PURPOSE:To scan the surface of a photosensitive body with equal distance thereby to easily form a high-quality image with less unevenness in the diameter of dots by projecting a light on the surface of said photosensitive body with the pitch of each luminous flux shifted, detecting the position of incidence of the luminous flux reflected from a rotary polygon mirror in a sub scanning direction on the surface of said photosensitive body for every reflecting surface of said rotary polygon mirror and controlling said photosensitive body. CONSTITUTION:Supposing that the number of reflecting faces of a rotary polygon mirror 4 is R and a reference reflecting face upon which the luminous flux from a semiconductor laser 2 is incident is Ro, when the luminous flux from a semiconductor laser 12 is incident upon the (i)-th reflecting face Ri from the reference reflecting face Ro in the rotary direction, the position of incidence of the luminous flux from the reference reflecting face Ro on the photosensitive drum 1 is arranged to be shifted by (RXN+i) pitch from that of the luminous flux from the reflecting face Ri wherein the distance of scanning lines is designated by 1 pitch and N is an integer. Accordingly, the scanning distance of the luminous flux from the reference reflecting face Ro on the surface of the photosensitive body becomes equal to that from the reflecting face Ri. Therefore, even when a plurality of luminous fluxes are used to scan, no unevenness in the pitch of the scanning lines is generated, thereby forming a favorable image on the surface of the photosensitive body.

IPC: H04N5/907
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a data processing device which can overwrites data even when sufficient vacant capacity does not exist in a recording medium. SOLUTION: When data of the latter half of an AVI(audio video interleave) film (file A) recorded in a memory card 36 is clipped, first, a CPU 32 makes other AVI file (file B) in the memory card 36. Next, the CPU 32 reads out data of a prescribed quantity from the file A, after the read out data is stored in a SDRAM 28, data preceding this data is erased from the file A. Thereby, when vacant capacity is secured in the memory card 36, the CPU writes data of the SCRAM 28 in the file B. This processing is performed repeatedly for required data for the file A. Consequently, the file B in which only required data is written is obtained.
