There is provided an image reading apparatus including a first reading sensor provided in a first reading unit and configured to read one surface of the sheet, a second reading sensor provided in a second reading unit provided to face the first reading sensor and configured to read an image on the other surface of the sheet, a first background portion serving as a reading background of the first reading sensor, a second background portion serving as a reading background of the second reading sensor, and a moving portion configured to integrally move the first reading sensor and the second background portion, wherein the first reading unit includes a sensor case in which the first reading sensor is provided, and the sensor case is fixed to the apparatus main body.

Image reading apparatus

A sheet feeding apparatus comprises a conveying path formed between an upper and a lower units facing each other; a feed roller which feeds a sheet by a portion partially exposed from an upper surface of the lower unit to the conveying path; a separation member disposed to oppose the feed roller; a stopper which stops entrance of the sheet into the conveying path by abutting against a sheet end in a closed state in which the stopper is moved in a direction to intersect with an exposed surface of the feed roller; a driving unit which drives at least the feed roller and the stopper; and a control unit which controls the driving unit to rotate the feed roller through a predetermined angle in a sheet feeding direction and to then open the stopper when feeding of the sheet is started from the closed state of the stopper.

Sheet feeding apparatus, control method thereof, and document reading apparatus

Scanner

A control program for using a peripheral apparatus is loaded from the peripheral apparatus to the memory of an information processing apparatus. A management program manages the display form of a control object based on execution of the control program. The control object displayed on the information processing apparatus can be switched between the non-display state and the display state. For example, the management program causes the information processing apparatus to execute return from the non-display state to the display state in synchronism with the user manipulation of the peripheral apparatus.

Program executed in information processing apparatus to control peripheral apparatus

A network scanning system has a control apparatus connected to a connection device via a network and includes a scanning application for remotely controlling a scanner, where the scanning application receives a command from the connection device and automatically transmits to a display unit of the connection device via the network without a user operation of the scanning application, a selection screen information, the connection device displays a selection menu and transmits, to the scanning application in the control apparatus, a selection item information specifying an item selected by a user of the display unit, and the scanning application automatically transmits, to the connection device without a user operation of the scanning application in the control apparatus, a control signal based on the selection item, and the scanning application in the control apparatus automatically controls the scanner remotely in accordance with the control signal via the network.

Network scanning system

A sheet feeding apparatus capable of obtaining a sufficient conveying force for pulling back double-fed overlapping sheets to a stacking tray side. A sheet feeding member feeds sheets incoming from a stacking tray which stacks the sheets into a conveying pass. A separating member separates the sheets fed to the conveying pass by the sheet feeding member one by one. A double feed detection sensor generates an output for detecting double feed of sheets fed to the conveying pass. A rotatable member contacts the fed sheet. A driving unit rotationally drives at least the rotatable member in a rotational direction for reverse feeding of sheets. A control unit controls the driving unit when the double feed of sheets is detected based on the output of the double feed detection sensor, such that the rotatable member is rotationally driven in the rotational direction for reverse feeding of sheets.

Sheet feeding apparatus

An image scanner device connected to a general information processing apparatus can be used on a network at a low cost, and further, the firmware of hardware for this purpose can be a maintenance-free firmware, thus user's convenience can be improved. A scanner/network connection apparatusto connect a scannerto a networkhas an LCD server to drive a LCD as a display unit, a touch panel task to transmit a touch position on a touch panel, and a SCSI server to connect the scannerto the network. A PCto control the scanner has a virtual LCD driver, a virtual touch panel driver, and a virtual SCSI driver, operating to provide an environment as if the LCD, the touch panel and the image scanner of the scanner/network connection apparatusare connected to the PC. The virtual LCD driver draws a screen image as a user interface for various operations, and the result of drawing is displayed on the LCD of the scanner/network connection apparatus. Thus an interactive operation environment can be provided to the user.

This invention has as its object to provide a highly reliable image reading apparatus in which both an image reading unit and photographing unit can obtain optimal images. To achieve this object, the apparatus has a light-emitting element array which illuminates a document to be read by a read sensor, and an illumination lamp which illuminates the document to be recorded by the photographing unit.

A sheet feeding apparatus has a pair of feeding roller and separating roller an inter-shaft distance changing mechanism for the pair of rollers, and sheet detecting means, and a sheet fed is rammed against the surface on which the feeding roller and the separating roller overlap each other to thereby correct skew feeding, and the feeding roller and the separating roller are moved away from each other to thereby feed the sheet. When the passage of the fed sheet between the feeding roller and the separating roller is detected the feeding roller and the separating roller assume a state in which sheet feeding is impossible. By the above-described operation being performed for each sheet, the correction of skew feeding and the separation of a sheet are effected by the feeding roller and the separating roller.
