An image reading apparatus includes a platen for placing the original, a reading device for reading the original placed on the platen to obtain image data in a first reading mode or a second reading mode; a transport device for transporting the original to be capable of returning the original to the platen; and a detection device for determining whether the image data read by the reading device is a first kind of data or a second kind of data. A control device operates the transport device for ejecting the original and outputting the image data read in the first reading mode when the image data is the first kind, and operates the transport device to return the original to the platen and actuates the reading device to read in the second reading mode when the image data is the second kind.

Image reading apparatus and image reading method

A sheet feeding device includes a sheet feed stacker and a transport belt disposed along a platen substantially horizontally; a discharge stacker disposed above the sheet feed stacker; and a light-shielding cover member provided between the platen and the sheet feed stacker for blocking light from the platen. The entire device is arranged above the platen, and it is easy to mount and dismount the device relative to the platen. An original is transported from the sheet feed stacker and to the discharge stacker along the platen with little damage.

An adhesive dispensing apparatus for dispensing an adhesive on a sheet bundle includes a support device for supporting the sheet bundle, a dispensing device disposed adjacent to the support device for dispensing the adhesive on an edge of the sheet bundle supported by the support device, and a transport device disposed adjacent to the support device for transporting the sheet bundle from the edge, to which the adhesive is applied, as a leading edge in a transport direction. A refilling device is provided for refilling the adhesive to the dispensing device, and a moving device moves the dispensing device between a dispending position where the adhesive is dispensed to the edge of the sheet bundle and a refilling position where the adhesive is supplied to the dispensing device from the refilling device.

Adhesive dispensing apparatus and image forming apparatus

An adhesive dispensing apparatus and image forming apparatus include a support device for supporting a sheet bundle, a dispensing device for dispensing an adhesive to an edge of the sheet bundle supported by the support device, and a transport device for transporting the sheet bundle with the edge having the adhesive dispensed by the dispensing device as a leading edge. A cover can be securely attached to the sheet bundle.

An image reading apparatus is provided with an optical reading device for scanning a stationary original placed on a platen to read image on the original; a drive device for moving the optical reading device at the first moving speed and the second or slow moving speed; a detection device for determining a type of image data read by the optical reading device as either the first type, i.e. monotone data, or the second type, i.e. color data; and a scan control device for obtaining and storing image data while scanning a document at the first moving speed. A switching control device switches the drive device to the second moving speed when the detecting device determines the image data read at the first moving speed to be the second type.

An image forming system which can ensure high operability according to an operator is provided. A control unitof a digital copying machineA changes an image which is displayed on a touch panelaccording to an ID specified by an IC card, a fingerprint of an operator, or input from the touch panelcorresponding to each operator in accordance with operator information stored in a hard disk. The control unitraises contrast of the image by changing the tone when an operator is the aged, makes an image to be displayed recognizable by changing the color when an operator the colorblind, indicates an image by enlarged characters when an operator is the poor sighted or a person with trembling fingers, changes languages according to an operator, and adjusts height of the touch panelaccording to height of an operator.

Image forming system with adaptability based on operator identification

A document feeding device mounted on an image processing device such as a copying machine for automatically feeding duplex original documents having images to be read on both sides to an image reading point one by one in such a manner that the document fed from a supply tray is reversed at a switchback part, sent through the image reading point to read the image on one side thereof, sent back to the switchback part to be turned upside down, again sent through the image reading point to read the image on the other side thereof, and then, discharged to a discharge tray. The documents can be rationally transported at high speed with high efficiency, and consecutively discharged to the discharge tray in the same order of page as those initially set on the supply tray.

Document feeding device

According to a document feeder for an image-forming apparatus of the present invention, when a double-sided document fed from a feed paper stacker, the document with the front surface thereof having been read out by a document reader unit is inverted in a switch-back path provided between the document reader unit and a discharged paper stacker on which documents after having been read out will be stacked, and is conveyed again to the paper reader unit so that the back surface is read out. The document after its both surfaces have been read out is again inverted in the switch-back path and then discharged onto the discharged paper stacker. With such a construction, the documents after having been read out can be stacked in the order of sequence of pages of the documents. Furthermore, the size of the device can be decreased, contributing to shortening the time required for reading the double-sided document and to increasing the efficiency for forming images. Accordingly, disadvantages, such as the damage to the document, contamination of the document reader unit or the jam of the document in a halfway of conveyance, can be suppressed or prevented. Moreover, the document conveyed to the switch-back path from the feeder section does not hinder the document discharged onto the discharge stacker from the switch-back path, making it possible to convey the document smoothly and efficiently.

Document feeder for image-forming apparatus and image-forming apparatus,

A document feed roller and registering rollers are driven through first and second one-way clutches so that the feed roller connected to the motor through the first one-way clutch is driven to forward a document to be processed only when the motor rotates in a positive direction, and the registering rollers connected to the motor through the second one-way clutch are driven to perform skew-correction and forward the document only when the motor rotates in a negative direction. The document is transported for a first part of a document feeding passage by the feed roller and for a second part of the passage by the registering rollers with efficiency merely by switching the rotational direction of the motor.
