In an image reading device, a region securing portion secures six page regions in a storage region of a volatile memory. A first conveyance control portion permits a document sheet conveyance device to convey first three document sheets among a plurality of document sheets in response to securing of the six page regions. A data recording portion stores line image data with specified resolution in the six page regions for each page of the plurality of document sheets. An image processing portion moves the plural pieces of the line image data in sequence from the page regions to a work region, and transfers post-processing data to another device. A second conveyance control portion permits the document sheet conveyance device to convey a fourth document sheet and onward among the plurality of document sheets one at a time in sequence following conveyance of the first three document sheets.

Disclosed is an image reading device including: a reader that reads an image on a continuous sheet; a conveying member that conveys the continuous sheet to a reading position; a calibration member that is movable to the reading position; a hardware processor that moves the conveying member and the calibration member so as to switch an arrangement between a first arrangement in which the continuous sheet directly faces the reader and a second arrangement in which the continuous sheet is located away from the reader and the calibration member directly faces the reader; and a pressing member that is disposed at the side of the reader parallel to a reading surface and that applies tension to the continuous sheet in the first arrangement so as to position a sheet surface of the continuous sheet at the reading surface.

A document scanning apparatus reading an image of a document includes a signal output unit configured to output a pulse signal at predetermined intervals, a sensor configured to detect a document set on a platen glass, the sensor having a light emitting unit configured to emit light in response to a pulse signal output from the signal output unit and a light receiving unit configured to output a detection signal in accordance with light output from the light emitting unit, and a control unit configured to receive the detection signal output from the light receiving unit. In this case, the signal output unit outputs the pulse signal at a different time point from the predetermined intervals in response to a request from an external apparatus.

A scanner includes a paper feeding roller set, a paper exporting roller set, a scanning module, a background and calibration roller, a main driving assembly, a first sleeve, a torque limiter and a stop-driving assembly. The paper feeding roller set and the paper exporting roller set are driven by the main driving assembly. The background and calibration roller includes a black background section, a white background section and at least one calibration section. The first sleeve sleeves the first end and is linked to the main driving assembly. The torque limiter is disposed between the background and calibration roller and the first sleeve and contacts the same. The stop-driving assembly is selectively abutted against two portions of the background and calibration roller.

An image forming apparatus in which at least part of an image scanner is disposed in an area below an original discharge unit and above an image forming unit.

A recording apparatus includes: a recording unit that performs recording on a medium; a medium discharging section that discharges the medium on which recording has been performed; a medium receiving section that receives the medium discharged by the medium discharging section; a face-down discharge path that guides, to the medium discharge section, the recorded medium with a recorded side thereof facing downward; a document movement path that is provided at an upper part of a housing constituting an outer casing of the recording apparatus and along which a document moves; and a reading unit provided in the document movement path to read the document. The medium receiving section also serves as a support tray that supports the document to be inserted into the document movement path or the document exiting from the document movement path.

The document conveying apparatus includes a body, a document tray, a guiding tray, a first support member that supports the document tray movably between a open position where a document is placed on the first document stacking face, and a close position where the document tray is closed, and a second support member that supports the guiding tray. The second support member positions the guiding tray at a first distance from the document tray, when the document tray is at the open position. The second support member positions the guiding tray at a second distance from the document tray, when the document tray is at the close position. The second distance is smaller than the first distance.

An image reader includes: a document transport path that is extended along a horizontal direction when the reader has a first posture and that transports the document; a transport roller that transports the document in the document transport path; a rotation-contact member document path rotating to have a posture in which a contact portion that comes into contact with the document blocks the document transport path and a posture in which the contact portion opens the document transport path; path A rotation center of the rotation-contact member is positioned on an upper side of the document transport path in the first posture and the contact portion projects from the upper side toward a lower side of the document transport path. A center-of-gravity position of the rotation-contact member is on a lower side from the rotation center in the first posture.

In a sheet feeder, an input passage has input and output ends and an input location. A first feeder module includes: a first input roller disposed on the input end; a first output roller disposed on the output end; and a first sensing device being disposed near the first input roller and generating a first signal transmitted to a processor upon sensing presence of a first medium. A second feeder module includes: a second input roller disposed on the input end; a second output roller disposed on the output end; and a second sensing device being disposed at the input location and generating a second signal transmitted to the processor upon sensing presence of a second medium. An image acquiring device acquires an image of the first or second medium. The processor controls enabled and disabled states of the first and second feeder modules. A control method of the processor is also provided.

A medium carrying device includes a first stopper, a second stopper, a lever, and a mechanism that, when the lever is positioned in a blocking area, places the first stopper at a first blocking position and places the second stopper at a second blocking position, when the lever is positioned in a opening area, releases the first stopper to be positioned at a first opening position and releases the second stopper to be positioned at a second opening position. When the lever is positioned at a boundary position in between the blocking area and the opening area, a lever portion of the lever gets positioned in between a first stopper portion of the first stopper positioned at the first blocking position and a second stopper portion of the second stopper positioned at the second blocking position.
