Abstract: An image forming apparatus includes an exhaust device. The exhaust device includes a duct main body and a duct mounting member. The duct main body and the duct mounting member are integrated with each other to form a first air passage and a second air passage that communicate a periphery of a fixing unit and an exhaust port of an apparatus main body. The first air passage is provided with a first fan and a first air passage filter. The second air passage is provided with a second fan and a second air passage filter. Each of the first fan and the second fan is a centrifugal fan. Each of the first air passage filter and the second air passage filter includes a filter for collecting at least ultrafine particle (UFP).

Abstract: A floor type multi-display apparatus includes a multi-display, transparent panels, and a plurality of support members. The multi-display includes a plurality of displays. The support members include first support members disposed between adjacent ones of the displays in a scattered fashion, and second support members disposed around the multi-display. The support members have respective plate portions positioned along and closely to edges of the displays. The support portion and the base portion of each of the first support members project toward two displays located closely thereto from the plate portion of the first support member. The support portion and the base portion of each of the second support members project toward only one display located closely thereto from the plate portion of the second support member.

Abstract: An image forming apparatus includes a protective member which is mounted to an opening of a rear panel and is formed as a resin tabular body in which a cover portion, an edge portion, and a plurality of holding portions are integrally formed. The protective member is fixed to the rear panel at the edge portion. The cover portion has a shape smaller than the opening. The edge portion has an external shape which is larger than the opening, and the edge portion being positioned outside the cover portion to provide a gap therebetween. The plurality of holding portions are independently Positioned in the gap and each of the holding portions connects the edge portion and the cover portion.

Abstract: A paper feeder including a fixed guide disposed at one side of a paper feeding tray. The fixed guide functions as a standard of position adjustment of documents, and faces in an orthogonal direction against a document transporting direction. The documents are fed from the document feeding tray by a pick-up roller, separated into one-by-one and fed to the downstream by a document separator comprised of a separate roller and a retard roller. These pick-up roller, separate roller, retard roller are disposed within the smallest width size of the documents stacked on the document feeding tray. The documents fed to the downstream are fed to a reading unit by the feed roller mounted in the movable guide side located opposite to the standard line. After the image data of the document is read by the reading unit, the document is discharged to the paper discharging tray by an extra roller.

Abstract: An image forming device includes a photoconductive drum, a motor which rotates the photoconductive drum, a charging unit which charges a surface of the photoconductive drum, an exposing unit which writes image information as an electrostatic latent image onto the charged surface of the photoconductive drum, a developing unit which develops the electrostatic latent image, a transfer unit which transfers the developed image onto a paper, a paper dust removing unit which removes paper dusts by contacting against the surface of the paper dust removing unit, and a rotation mechanism which intermittently rotates the paper dust removing unit.

Abstract: A drive power transmission mechanism situated between a drive motor and a pick-up roller for transmitting a drive power to the pick-up roller from the drive motor to rotate the pick-up roller under a normal condition. The rotating pick-up roller picks up a sheet at a time from a stack of sheets piled up on a paper feed tray. The transmission mechanism includes a torque limiter that interrupts drive power transmission to the pick-up roller from the drive motor when the pick-up roller contacts an empty paper tray. The drive power transmission mechanism also includes a clutch for preventing drive power transmission from the pick-up roller to the drive motor. The drive power transmission from the pick-up roller to the drive motor occurs, for example, when both the pick-up roller and a feed roller contact the same sheet and the pick-up roller rotates faster than a predetermined speed.
