摘要:
If a moving speed of a transparent member is determined as not larger than a prescribed moving speed, a used transmission portion out of a transmission portion of the transparent member is changed to a prescribed transmission portion that has been set in advance. If the used transmission portion is changed to the prescribed transmission portion, the moving speed of the transparent member is set to a moving speed based on the prescribed transmission portion.

The present invention provides an image reading apparatus: transporting a document using an automatic document feeding unit in a predetermined direction while the document floats above a platen glass member; reading an image on the document, at a predetermined reading location, by irradiating a portion on the document at the reading location using a light source disposed below the platen glass member, and by receiving reflected light from the portion on the document; converting the reflected light into image data; detecting the floating amount of the document from the platen glass member; and setting a value of an image parameter for correcting the image data for the document, based on the detected floating amount of the document.

An automatic document feeder device 100 has a device body 110 disposed on a platen 210 of a document reading device 200 and pivotably openable relative to the device 200 by being hingedly connected thereto. The device 100 includes detectors 130, 140 for detecting a document-stack state of at least one of a feeder and an output tray 111, 112 provided on the body 110, a driver 160 for driving the body 110 to be pivotably opened in an upward direction from the platen 210, an instructor 179 for giving an instruction for the driving, and a controller 172 for, based on a detection result of the detectors 130, 140 in priority to the instruction, to permit or forbid the driving, or to control an amount of the driving. When the device body is automatically opened, documents in the feeder or the output tray are unlikely to fall off.
摘要:
An object of the present invention is to provide an image reading apparatus that has a simple mechanism for ejecting dust collected from a transparent member by a cleaner to the outside, thereby preventing stripe noise from being mixed into read image data.Disclosed is an image reading apparatus, wherein while an automatic document feeder is feeding a document (D) such that the document (D) passes over a reading glass (40), an image of the document is optically read at a reading position (A). Above the reading glass (40), a brush type cleaner (45) is disposed to face to the reading position (A) and to be capable of rotating. At a downstream position from the cleaner (45) with respect to a document feeding direction (B), a duster (46) is disposed for a dusting operation to remove dust from the cleaner by slapping against the cleaner (45). Before the leading edge of the document (D) comes to the reading position (A), the cleaner (45) rotates to clean the reading glass (40), and while the document (D) is covering the reading glass (40), the duster (46) slaps against the cleaner (45) to dust the cleaner (45).
摘要:
When a print job is received from the network, subsequent processing depends on whether the print job includes authentication information. Where the print job includes authentication information, the print job is stored in a memory while being associated with the authentication information. When authentication information is received from the network thereafter, a print controller selects, from among the print jobs stored in the memory, the job that is associated with authentication information that matches the received authentication information, and causes it to be printed.

An image reading apparatus is disclosed. The image reading apparatus includes an automatic document feeding unit that transports a document in a predetermined direction while the document floats above a platen glass member and a light source disposed below the platen glass member that irradiates a portion on the document at a predetermined reading location such that reflected light from the portion on the document is converted into image data and a floating distance between the document and the platen glass member is detected to set a value of an image parameter for correcting the image data for the document, based on the detected floating distance between the document and the platen glass member.
摘要:
The purpose of the present invention is to provide an image forming apparatus capable of excellent detection of the position of a toner mark on a transfer member without being influenced by transfer member thickness variation or position oscillation, and capable of high precision detection by eliminating errors due to differences in measurement timing by directly detecting the overlay dislocation of a plurality of toner layer with the same timing. The image forming apparatus of the present invention attains these goals by detecting the distance from the sensor to the transfer member 6, and the distance from the sensor to the toner mark P, and determining the position of the toner mark P via the difference in the distances. In this way the positional dislocation of the toner mark P can be detected with excellent precision.

Copying apparatus is provided in which outline copying for only a designated area of an original image can be easily selected. An area for the outline copying can be designated and images inside and outside the designated area can be copied in different colors. The arrangement includes a plurality of keys for designating an area of an original image to be copied and a scorotron charger for causing a potential in areas other than the outline portions of an electrostatic latent image, formed on a photoreceptor drum, to be substantially equal to a potential in an area containing the image. An eraser unit is provided for erasing the charge in an area where development is not required and a developing device develops the electrostatic latent image. A transfer charger is provided for transferring the image developed by the developing device onto copying paper. When an area of the original images designated and an outline image forming mode is selected by the operator of the machine, two copy operations are performed to composite an outlined image formed inside or outside the designated area and a normal image formed in the area which does not include the outline image so that a composite image is copied onto the copy paper.

An image forming apparatus comprises: an operation part having a display area and operable to receive an input from a user; a first display part operable to display, in a part of the display area, (i) a first image to be visible only from a range of a first viewing angle and (ii) a second image to be visible only from a range of a second viewing angle that does not overlap with the range of the first viewing angle; an audio output part operable to output an audio explaining the first image; and a second display part operable, while the audio explaining the first image is being output, to display, in a remaining part of the display area, a notification indicating that the audio explaining the first image does not correspond to the second image, such that the notification is visible from the range of the second viewing angle.

An image forming apparatus that warns that a JOB fails to be pulled out is provided. Warning processes executed by a CPU of a printer that is one example of the image forming apparatus includes the steps of determining whether a JOB list is updated, setting a job counter JB_S_CTA for checking JOB at an initial value “1” and setting an upper limit counter JB_S_CTB at an upper limit value when the JOB list is updated, executing a failure-to-pull-out warning process if JOBs counted by JB_S_CTA belong to the same client, and incrementing the JB_S_CTA by “1”.
