Abstract:
A document feeder includes a conveying path extended from a document supplying position to a reading position, a first conveying roller pair provided upstream from the reading position and nipping and conveying the document, a second conveying roller pair provided downstream from the reading position and nipping and conveying the document faster than the first conveying roller pair, a post-reading conveying path extended downstream from a nipping position of the second conveying roller pair, the post-reading conveying path being located above a plane tangent to the second conveying roller pair at the nipping position running in a reverse sheet feed direction, and a third conveying roller pair provided on the post-reading conveying path and nipping and conveying the document conveyed from the second conveying roller pair at a conveying force equivalent to that of the second conveying roller pair.
Abstract:
An automatic document feeder, which is capable of feeding a document for double-sided reading, includes a document feed path connecting an input tray and an output tray, a bidirectional feed path connected to a connection position of the document feed path, a bypass diverged from a branch position of the document feed path and connected to the connection position, a guide flap that changes a position thereof between a first guide position and a second guide position, and a guide flap that changes a position thereof between a third guide position and a fourth guide position.
Abstract:
In a document feeder, a driving control unit feeds a document by a switch-back feeding unit, guides again the document from a document feed path to a bidirectional feed path, and then discharges the document from the document feed path to a document discharging section, when the feeding of the document is in a double-sided scanning feeding mode and in a status during first side feeding. The driving control unit feeds the document by the switch-back feeding unit and then discharges the document from the document feed path, when the feeding of the document is in the double-sided scanning feeding mode and in the status during second side feeding. The driving control unit discharges the document from the document feed path without feeding the document in the switch-back manner, when the feeding of the document is in the double-sided scanning feeding mode and after the second side feeding.
Abstract:
Feeding systems for documents or other sheet materials include: (a) an inlet; (b) an outlet; (c) a feed path extending between the inlet and outlet; and (d) a feed system that moves materials along the feed path. The systems further may include: (e) a bidirectional feed path extending from the feed path; (f) a supply system that moves materials to the feed path; (g) a bidirectional drive system that moves materials along the bidirectional feed path; and/or (h) a bidirectional feed path access control system. Drive systems may be provided for driving the feed system and at least one of the supply system, the bidirectional drive system, and/or the access control system such that operation of the feed system is independent of operation of the other systems and/or such that a single motor may be used to drive any or all of the systems.
Abstract:
An image reading apparatus includes a light source for irradiating a document paper with light, and a photoelectric conversion unit for detecting the light reflected by the paper. The light source is connected to a first harness which is connected to a connector board via a first connector. The photoelectric conversion unit is connected to the second harness which is also connected to the connector board via a second connector. A third harness is further connected to the connector board via a third connector for power supply and signal transmission. The connector board is formed with a plurality of test pads used for connection to an outside test apparatus without detaching the first and second connectors from the connector board.
Abstract:
An image forming apparatus includes an exposure lamp which is detachably stored in a lamp house. A cover to open and close an opening of the lamp house is prohibited from being opened by an original supporting stand while it is in an operating region for exposure of an original to light. A release member allows the original supporting stand to move beyond the operating region so that the cover can be opened to exchange the exposure lamp. When the original support member is moved beyond the operating region, an electric power source is cut off by the release member. A moving member connected with the cover also cuts off the electric power source when the cover is opened. A reflecting mirror provided around the exposure lamp is moved away from the exposure lamp automatically by a link member when the cover is opened.
Abstract:
In a heat/pressure applying unit, a pair of rollers cooperate with each other to define a nip therebetween. A recording medium is caused to pass through the nip at which at least one of heat and pressure is applied to the recording medium by the pair of rollers. First and second strippers are associated with at least one of the pair of rollers. The first stripper is arranged adjacent the nip for stripping the recording medium from the one roller. The second stripper is arranged at a location spaced from the first stripper along a peripheral surface of the one roller, for forcibly stripping the recording medium from the one roller.
Abstract:
An exposure device having a light source section which includes a light source and a pair of light reflection means. One of the light reflection means is disposed movable toward and away from remaining reflection means so as to provide an open space for facilitating handling such as replacement of the light source.
