摘要:
A photographic flash exposure control system for a camera associated with a flash device. In conformance with a preselected shutter interval, an effective exposure aperture of a diaphragm device is computed by a computing circuit of the system. The total flash energy available from the flash device is automatically controlled in accordance with the luminance of the subject being photographed, to thereby provide correct exposure for complex lighting situations.

An image forming apparatus includes a member to be cleaned and a cleaning roller driven by contact with the member to be cleaned, and the apparatus is configured such that abrasive grains and at least one of a release agent and a solid lubricant are supplied to the member to be cleaned and that the supplied abrasive grains and the supplied at least one of a release agent and a solid lubricant move on a surface of the member to be cleaned in an axial direction of the cleaning roller.
摘要:
The invention provides a toner for electrostatic image development, containing a toner particle and external additive particles adhered to the surface of the toner particle, each of the external additive particles being constituted of plural irreversibly coalesced primary particles.
摘要:
A sheet-handling device comprising an intermediate conveyer passage, an intermediate tray, introduction rollers, conveying rollers and a controller. The controller rotates the introduction rollers and the conveying rollers forward and reverse so as to convey two pieces of sheets successively introduced into the intermediate conveyer passage until their trailing ends separate away from the introduction rollers. The conveying rollers are halted in a state where the leading ends are nipped. After the leading ends of the two pieces of sheets have been nipped in an overlapped manner by the conveying rollers, the conveying rollers are rotated forward to convey the two pieces of overlapped sheets into the intermediate tray.

A sheet post-processing apparatus (1) includes a punching unit (P), an end-binding unit (S) which aligns end portions of a sheet bundle piled on a processing tray (2) and performs a stapling process, and a middle-binding and middle-folding unit (C) which performs a stapling process on the center of the sheet bundle and then folds centering around the stapling portion to be in a brochure form. The middle-binding and middle-folding unit (C) is independently provided on the lower side of the end-binding unit (S) and a middle-binding and middle-folding feeding path (27) feeds sheets to the middle-binding and middle-folding unit (C) without via the processing tray (2) of the end-binding unit (S).

A commodity trade assisting system, for assisting a shop in exhibiting a commodity traded at the shop in a virtual shop and managing it, includes: a communication unit for communicating with a shop terminal which records and manages information on the commodity over a network; a database for storing commodity information sent from the shop terminal as information on the commodity to be sold over the network and received by the communication unit; and an application server (AS) having a function of preparing and posting explanation and other reports about the commodity shown on a commodity guide page of the virtual shop with reference to the commodity information sent from the shop terminal and received by the communication unit and a function of transmitting a signal representing a request to send back information on the commodity to be sold over the network at predetermined time intervals to the shop terminal, updating the information in the database according to the information sent back from the shop terminal in response to the request, receiving information on an order of the commodity shown on the commodity guide page and ordered, and updating the information in the database according to the order information.
摘要:
An office machine includes a housing body, a bearing unit secured to the housing body and a caster wheel supported to the bearing unit to be rotatable about a horizontal axis. The bearing unit is secured to a bottom plate forming a lower face of the housing body. The bottom plate defines an opening, through which the caster wheel is introduced to a position upwardly of the bottom plate to be supported to the bearing unit.
