摘要:
A sheet feeder is provided. The sheet feeder includes a roller to feed a sheet, a motor to rotate the roller, and a motor controller to control rotation of the motor by a feedback control. The motor controller detects a condition of the sheet based on a value acquired in the feedback control at the time a load is applied from the sheet to the roller, while performing a stop control to stop the roller at a designated stop position. The stop control is performed after the motor is rotated in a direction opposite to a direction of feed of the sheet.

A non-transitory computer-readable storage medium stores image data for adjustment of image formation. The image data includes a cross-hair formed in a corner of a recording medium, and a corner edge detection mark formed to detect a folded corner edge of the recording medium from read data obtained when the corner of the recording medium including an area where the cross-hair is formed on one side is folded to an opposite side to the one side of the recording medium and an image reader reads the opposite side.

The reading device includes an image reading unit, a document feeder unit, a table document detection unit for detecting presence or absence of a document on the place-reading contact glass, a document set sensor for detecting setting of the document, a size detection unit for detecting a size of the document on the document tray, and an open/close detection unit for detecting open and close of the document feeder unit. In a determination necessary state in which setting of the document is not detected while an object on the document tray is detected, it is determined to execute feed reading, or to execute place reading, or to be disabled to confirm to execute the place reading or the feed reading, based on whether or not there is a document on the place-reading contact glass and based on history information.

An image forming apparatus includes a reading unit, a document conveyance unit, a sheet storage unit, a printing unit, a first and second determination unit, and a control unit. The reading unit reads a document. The printing unit performs printing on a sheet fed from the sheet storage unit. The first determination unit determines a first size of the document based on a size of a sheet stored in the sheet storage unit. The control unit causes the document conveyance unit to convey the document and causes the reading unit to read the document based on the determined first size. The second determination unit determines a second size of the conveyed document. In response to the determined first size not matching the determined second size, the control unit causes the document to be conveyed again and causes the document to be read again based on the determined second size.
摘要:
Devices, methods, and software are disclosed for an interactive user interface for capturing a frame of image data having a representation of a feature. In an illustrative embodiment, a device includes an imaging subsystem, one or more memory components, and one or more processors. The imaging subsystem is capable of providing image data representative of light incident on said imaging subsystem. The one or more memory components include at least a first memory component operatively capable of storing an input frame of the image data. The one or more processors may be enabled for performing various steps. One step may include receiving the image data from the first memory component. Another step may include attempting to identify linear features defining a candidate quadrilateral form in the image data. Another step may include providing user-perceptible hints for guiding a user to alter positioning of the device to enhance a capability for identifying the linear features defining a candidate quadrilateral form in the image data.

A document scanner (10) includes an input tray (20) for holding documents (11). An input image capture device (30) captures at least a portion of the images of documents in the input tray. An image processor (65) determines characteristics of documents in the input tray, and the documents are processed based on the characteristics. At least one characteristic is document length (70), or width (80), or position (170), or other characteristics. An ultrasonic zone (160) detects the documents; and the ultrasonic zones are enabled or disabled in at least one location down the document based on at least one characteristic.
