A high-speed serial switch fabric is configured to perform a mapping of a traffic class that is capable of differentiating traffics onto a virtual channel. The high-speed serial switch fabric connects a plurality of devices. A traffic-class setting unit sets, when a conflict occurs between devices connected to the high-speed serial switch fabric, the traffic class for each of traffics in the devices having the conflict. A channel setting unit assigns each of set traffic classes to different virtual channels, and gives a priority of data communication to each of the set traffic classes.

An apparatus for converting optical information into an electrical information signal includes a plurality of one-dimensional conversion arrays arranged in parallel form. Each one-dimensional conversion array has first and second photoelectric conversion structures integrally formed. The first photoelectric conversion structure has photoelectric conversion elements each having a light receiving surface onto which an information light is projected. The second photoelectric conversion structure has photoelectric conversion elements each having a sweep light receiving surface onto which a sweep light is projected. The sweep light has a cross section which simultaneously scans the sweep light receiving surface of one of the photoelectric conversion elements included in each of the one-dimensional conversion arrays. The electrical information signal is read out from the photoelectric conversion elements provided in the first photoelectric conversion structure when the sweep light is projected onto the photoelectric conversion elements provided in the second photoelectric conversion structure.

An image forming apparatus for forming an image corresponding to a subject is provided, which image forming apparatus includes a taking lens for making an optical image corresponding to the subject, and a dividing portion for dividing the optical image transmitted via said taking lens into several adjacent optical image parts. The image forming apparatus further includes several solid-state image sensors corresponding to the number of the optical image parts, each of said solid-state image sensors receiving a corresponding optical image part from among the several optical image parts from the dividing portion and outputting an image signal corresponding to the optical image part, the optical image parts received by said solid-state image sensors being adjacent to each other. Finally, the image forming apparatus includes an image forming portion, coupled to said solid-state image sensors, for forming an image part corresponding to the respective optical image part based on the image signal transmitted from one of said solid-state image sensors, and for composing each image part to form the image corresponding to the subject by arranging the image parts to be adjacent to each other like the optical image parts.

A light deflector for use in a laser printer, for example, is composed of a motor having a drive shaft and a light reflecting member such as a rotating multiple-surface mirror or a hologram. The motor is subjected to magnetic field ripples the number of which is equal to a multiple by an integer of the number of light reflecting surfaces of the light reflecting member.
