Abstract: An auto document feeder includes a lead path, a first reverse path, a second reverse path, and a both surfaces eject path. The lead path guides a document from a left side to a right side of a read position. The first and second reverse paths are connected to the lead path, and reverse the document to guide the document from the right side to the left side of the read position. A both surfaces eject path is connected to the first and second reverse paths and guides the document whose image information of a second surface has been read to eject further to the right side than the read position. A shared curve path shared by the lead path and the both surfaces eject path includes a portion between the read position and a portion in which a lead curve path protrudes the most.

Abstract: A copier includes an image scanning device having an ADF, and an image forming device having a duplex printing function that forms an image first on a back side surface of recording medium. The ADF includes an original tray, a separation unit, a first double-surface path, a second double-surface path, a discharge path, and a discharge tray. Originals with their front side surfaces facing upward can be placed on the original tray. The first double-surface path guides the original separated by the separation unit in such a manner that aback side surface of the original passes through a scanning position of a scanner unit. The second double-surface path reverses the original, which has passed through the first double-surface path and has had the back side surface scanned, and guides the original to the scanning position of the scanning unit so that the front side surface of the original can be scanned.

Abstract: In a paper transportation device, a separation pressure adjusting screw is provided in a transportation device main body under a separating pad holder. One end of a coil spring makes contact with the separation pressure adjusting screw, and another end of the coil spring makes contact with a position located away from a separating pad in the separating pad holder. A screw adjusting hole is provided on the separating pad holder for adjusting a screwed-in amount of the separation pressure adjusting screw from above.

Abstract: A paper tray unit includes a paper size sensor which is attached to a paper tray and determines a paper size in a paper width direction by detecting a position of a paper width guide. In the paper tray unit, a movable member moves in a paper feed direction accompanying movement of the paper width guide. The position of the paper width guide is detected by the paper size sensor detecting or not detecting the movable member.

Abstract: A paper feeder includes a sheet supply unit that feeds sheets placed on a sheet placing part, a separating roller the separates the sheets fed by the sheet supply unit one sheet at a time and supplies each sheet to a sheet transportation path, a transportation roller that transports the sheets provided downstream of the separating roller and a link mechanism connected to the transportation roller via a transmitting unit. When the transportation roller rotates in a sheet transporting direction, the link mechanism swings so that a shutter opens the sheet transportation path and maintains an opened state. When the transportation roller rotates in a direction opposite to the sheet transporting direction, the link mechanism swings so that the shutter closes the sheet transportation path.

Abstract: An image forming apparatus includes a scanning unit that scans a document, a recording unit including a transfer unit that forms an image on a recording sheet, and a fuser unit that affixes a toner image on the recording sheet transferred by the transfer unit. A sheet discharging unit discharges the recording sheet and a recording sheet discharging tray stacks recording sheets discharged from the sheet discharging unit in a space formed above the scanning unit. The sheet discharging unit includes a guide member curving the recording sheet in a convex shape in a width direction.

Abstract: In a connection part of vertical transfer registers with respect to a horizontal transfer register, transfer electrodes to which clocks &phgr;V1, &phgr;V2A, &phgr;V3A, &phgr;V2B, &phgr;V3B, and &phgr;V1A are applied are arranged in the cited order. In a horizontal transfer register 6, transfer is conducted by 3-phase clocks &phgr;H1A, ØH1B, and &phgr;H2. By activating clocks, signal charges of a channel denoted by A-A′ and channels equivalent thereto are first transferred to undersides of electrodes of &phgr;H1A of the horizontal transfer register. The signal charges are transferred in the rightward direction to underside of electrodes of &phgr;H1B. Subsequently, signal charges of a channel denoted by B-B′ and channels equivalent thereto are transferred to undersides of electrodes of &phgr;H1B of the horizontal transfer register, and mixed with the signal charges previously transferred.

The seasoning liquid is applied on the surfaces (13) of hydrophobic rollers (12) having a rugged surface (11), and the dried laver (4) is brought into contact with the rollers (12), by which the seasoning liquid on the surfaces (13) is applied to the dried laver (4).

Abstract: In a solid-state image pickup device comprises a solid-state image pickup section (10) including a substrate and a plurality of photoelectric converting sections formed on the substrate, the photoelectric converting sections accumulates, in response to incident light, electric charges during a controllable accumulating time interval in each frame period as signal charges in synchronism with a frame rate. Connected to the substrate, electronic shutter means discards disused charges during a discarding time interval in the frame period from the photoelectric converting sections to the substrate. The discarding time interval is equal to a difference between the frame period and the controllable accumulating time interval. Connected to the solid-state image pickup section, a timing pulse generating section (20) controls the controllable accumulating time interval.
