Abstract: An electromagnetically operated sheet diverter for an image forming apparatus. The sheet diverter diverts a sheet from a common path to one of two possible paths upon discharge from the image forming apparatus. The sheet diverter is small and compact, making the sheet diverter suitable for desktop image forming devices. A main controller operates the sheet diverter to divert sheets depending on the tray of origin. The sheet diverter has a holding bracket. An electromagnet is mounted to the holding bracket. A spring-biased paper diverting member is selectively attracted by and brought into contact with the electromagnet only when the magnet is activated. A longitudinal shaft is tightly held by the paper diverting member and is selectively rotated along with the paper diverting member. The longitudinal shaft has a plurality of fitting grooves, which are spaced out at regular intervals and have a D-shaped cutting configuration.

Abstract: A sheet transport system for an image-forming apparatus including a scanner unit on an upper part of an image-forming unit. A paper ejecting path ejects an image formed paper sheet to an ejected paper stacker via the image-forming unit. A scanning sheet path conveys an original document through an original document platform to a scanned paper stacker via the scanner unit. A sheet path selector selects one of the paper ejecting path or scanning sheet path, the scanning sheet path and the paper ejecting path crossing each other.

Abstract: A copying apparatus includes a first cassette for stacking recording sheets each having a protruding portion, a second cassette for stacking recording sheets having no protruding portion, a detecting unit for detecting a protruding portion of an original to be copied, and a copy unit for copying an image of an original onto the recording sheet fed from the first cassette in the case where the protruding portion of the original is detected by the detecting unit and for copying the image of the original onto the recording sheet fed from the second cassette in the case where the protruding portion of the original is not detected by the detecting unit.

Abstract: An image forming apparatus which includes a document transporting device for sequentially transporting a group of original documents to a predetermined position on a document platen one by one. The group of original documents includes main body pages and partition pages which have a dimension different from the dimension of the main body pages. The image forming apparatus also includes an image forming device for forming an image of each of the original documents on a respective copy sheet in synchronization with an operation of the document transportation device. Sheet supplying means which have a plurality of supply portions and which feed copy sheets one at a time from the supply portions to the image forming device are also included.

Abstract: An image reading and printing apparatus having a housing, a printing part located in the upper part of the housing, an image reading part located in the lower part of the housing, a sheet feeding part located in the lower part of the housing below the image reading part and receiving thereinto a sheet inserted from the lower part of the front face of the housing, a C-like shape sheet conveying path through which the sheet is led from the sheet feed part to the printing part, and is discharged outside of the housing from the upper part of the front surface thereof, and a C-like shape document conveying path through which a document inserted from the lower part of the front face of the housing is led to the image reading part, and is then discharged outside of the housing from the front face of the housing, the C-like document conveying path being surrounded by the C-like sheet conveying path, thereby making it possible to miniaturize the image reading and printing apparatus and to absorb a shift between the ti

Abstract: An image formation apparatus for transferring an image of an original document to a copy paper sheet. Original documents are placed in an original document tray and copy paper sheets are stored in a paper tray. The original document tray has a tray sensor for sensing the original document placed on the original document tray. Upon transferring the original documents to an image scanning apparatus, a regi-sensor measures the length of the original document when the original document is transported to the scanning apparatus. A value corresponding to a transport distance is stored until the original document leaves the tray sensor based on the length of the original document. The tray sensor can sense when the original document is transported more than the transport distance corresponding to the value stored. Paper is fed out of the copy paper sheet tray to the image transfer apparatus when the controller senses the original document.

Abstract: An image forming apparatus having an overall original-copy recording function for effecting image recording automatically in one simple operation without loss of any part of the overall original image. A scanner is used to scan an original copy to detect the original-copy size. In the absence of an original-copy skew, the original-copy size is assumed to be equal in size to the original image, whereas in the presence of the original-copy skew, the size of a square internally touched by the skewed original copy is made the original image. Selection is made of copying paper whose size is greater than a combination of the detected original-copy size and a copying paper skew and of a memory corresponding to the selected copying paper size, so that the original image that has been read is stored. The original image is formed on the selected copying paper before being output.

Abstract: An apparatus and method is provided for controlling the insertion of one or more special insert sheets into a steam of regular imaged sheets. A coded sheet is placed into a sheet stack in a position where an insert sheet is to be placed. Sheets are removed from the stack one by one and transported along a path past a sensor toward a finishing apparatus. When the sensor detects a coded sheet, the coded sheet is diverted from the stream and later replaced with an insert sheet.
