摘要： An optical disk apparatus for an optical disk enclosed in a disk cartridge comprises a casing for accommodating the cartridge through a cassette insertion aperture formed therein. A disk drive motor for rotating the optical disk, a loading assembly for detachably loading the cartridge on the disk drive motor, and an optical pickup device for recording data on and/or reproducing data from the optical disk are provided in the casing. Deflecting member provided for sealing the periphery of the optical pickup device against the flow of outside air introduced in the casing. A specific air-seal or door structure is provided for preventing introduction of air from the cassette insertion aperture into the casing. In the case that the optical pickup device comprises an optical head casing and an optical system accommodated in the optical head casing, the optical head casing is provided with air-supply means for supplying pressurized air into the optical head casing to maintain the interior of the optical head casing at a pressure higher than the exterior thereof.

摘要： An electrophotographic apparatus is provided for forming an electrostatic latent image on a photosensitive device to form a composite image on an intermediate transfer device which is in turn transferred onto a transfer sheet. Power from one drive motor is first transmitted to the intermediate transfer side and then transmitted to the photosensitive device side so that both the photosensitive device and intermediate transfer device are driven by one drive motor. Thus, even if the peripheral speed of the intermediate transfer device temporarily varies due to the contacting and separating operations of a cleaning device and a transfer roller with respect to the intermediate transfer device, the rotational speeds of the intermediate transfer device and the photosensitive device always become equal to each other to prevent a deterioration of the image quality to be outputted.
