A sheet destruction and discarding apparatus for destroying and discarding a sheet, comprising a destruction and discarding unit that destroys and discards the sheet based on a determination whether or not the sheet is allowed to be destroyed and to be discarded; a notification unit that notifies that the sheet is not allowed to be destroyed and to be discarded and a reason why the sheet is not allowed to be destroyed and to be discarded when the determination indicates that the sheet is not allowed to be destroyed and to be discarded; an insert sensor that detects whether or not the sheet is taken off, wherein, after the notification unit notifies that the sheet is not allowed to be destroyed and to be discarded and the reason, a state of the insert sensor changes to an off state and then a state of the sheet destruction and discarding apparatus changes to a standby state.

Recording medium destruction and discarding system, recording medium destruction and discarding method, recording medium destruction and discarding apparatus, recording medium management apparatus, and recording medium management system

A disposal processing apparatus comprises: a disposal processing section that disposes of a recording medium; an arrival detecting section that detects whether the recording medium has reached the disposal processing section; and a judging section that judges whether the recording medium has been disposed of by the disposal processing section based on a detection result of the arrival detecting section.

Disposal processing apparatus, disposal processing information management system, and disposal processing method

A recording medium destruction and discarding system for destroying and discarding a recording medium, includes: a registration unit that registers an identification information appended to the recording medium associated with an attribute information of the recording medium; a reading unit that reads the identification information appended to the recording medium; a determination unit that determines whether or not the recording medium may be destroyed and discarded based on the attribute information registered in the registration unit associated with the identification information read by the reading unit; and a destruction and discarding processing unit that performs a destruction and discarding process based on the determination result of the determination unit.

A disposal processing system is provided and includes: a disposal section that disposes of a document; a reading section that reads identification information of the document, the identification information being attached to an image on the document; a judging section that makes a judgment whether disposal of the document is permitted on the basis of the identification information; and a controller that controls the disposal section so that the disposal section disposes of the document at least one of: when the judging section makes a judgment that the disposal of the document is permitted; and when the controller acquires information indicating that the disposal of the document is permitted while the judging section makes a judgment that the disposal of the document is prohibited, and so that the disposal section does not dispose of the document when the judging section makes the judgment that the disposal of the document is prohibited.

Disposal processing system and disposal processing apparatus

A document management system comprises a document management apparatus that manages a document ID by associating the document ID with a storage time of the document, and checks the storage time in response to an inquiry about a permission of destroying the document and gives a permission of destroying the document when the storage time has expired, and a document destruction apparatus including a mode selection unit that selects one of a first destruction mode and a second destruction mode and an execution unit that destroys the document according to a destruction mode selected by the mode selection unit. The execution unit destroys the document without reading the document ID in the first destruction mode, and reads the document ID to inquire the permission of destroying the and destroys the document when the document management apparatus gives the permission of destroying the document in the second destruction mode.

Document management system and document destruction apparatus

A scanner is provided with an illumination lamp for emitting light to a first side of a document from one side of a transfer path and a CCD image sensor for receiving light reflected from the first side of the document, and a CIS provided in a document feeder is provided with an LED for emitting light to a second side of the document from the other side of the transfer path and a line sensor for receiving light reflected from the second side of the document. The illumination lamp is a xenon lamp, and the LED is a white LED having emission characteristics different from those of the xenon lamp. To the CIS, a filter is attached, which brings emission characteristics of light emitted from the LED onto a document closer to those of light emitted from the illumination lamp onto the document.

Image reading apparatus and image reading module

CCDas an image reading part reads a copy at the upstream and downstream of reading positions, and image data B and A at each of the reading positions are obtained from an output delay circuit and a shading correction circuit, respectively. A streak detectorcompares the image data A with B, and outputs black streak detecting data indicating that the image data A contains black streaky noises, when the image data is not coincident in succession as to a plurality of pixels arrayed in the sub-scanning direction. A streak eliminator normally outputs the image data A, but it outputs the image data B instead of the image data A with regard to the pixels from which the black streak detecting data containing the noise is outputted. The image data reading device of present invention being thus constructed, the device is able to accurately detect streaky noises by adhesion of thrashes to the reading unit, even if there are speed variations in the copy feeding.

Image reading device and method of the same

Vertical scanning speed and the accumulation time of photoelectric conversion elements arranged in a CCD are set in accordance with a resolution and a magnification set on a control panel. The accumulation time is set in a timing control section and the CCD is driven. The vertical scanning speed is set in a scan motor or is sent to an ADF control section for controlling a move of an original or an optical system, whereby the original is vertically scanned in response to the setup resolution and magnification for sampling the original image. As the accumulation time is changed, CCD output changes. Thus, to correct it, a gain and offset values as the accumulation time is changed are set in gain control sections, an odd/even correction section, and an offset correction section.
