摘要:
A copying machine including a specifying unit movable along the document support for specifying a particular point and operable to divide an area of the document support into a first area, delimited between the exposure start position to the particular point, and a second area delimited between the particular point and the exposure terminating position; a first developing unit with a mass of developing material of first color therein and operable to develop an electrostatic latent image into a visible powder image, a second developing unit with a mass of developing material of second color therein and operable to develop the electrostatic latent image into a visible powder image, and an erasing unit for erasing the electrostatic latent image before the electrostatic latent image is developed by one of the first and second developing unit; a mode specifying unit for specifying relative to the first and second areas one of a first mode in which the electrostatic latent image on the photosensitive medium is developed into the visible powder image of first color with the use of the first developing unit, a second mode in which the electrostatic latent image on the photosensitive medium is developed into the visible powder image of second color with the use of the second developing unit, and a third mode in which the electrostatic latent image on the photosensitive medium is erased with the use of the erasing unit.
摘要:
An image forming apparatus which forms images on sheets fed selectively automatically or manually, and finishes copy sheets such as stapling them into booklets and/or stamping them under a control provided by an electronic control system. The control system prohibits simultaneous operations of finishing and feeding sheets manually.

A data input apparatus for inputting control information to a data card for controlling a machine by means of the same comprises a memory in which specification of the machine to be controlled by the card have been stored and an operation panel for inputting operation mode of the machine. If the inputted operation mode is out of the stored specification of the machine, the control information of the machine is not inputted to the data card.

The number of copied sheets of paper accommodated in a staple tray for stapling process are counted by a counter. A transport path changeover member is switched over from a guide position to convey copy paper to the staple tray to a guide position to convey the copy paper to another discharge tray where stapling process is not performed corresponding to the counter value reaching the limit of stapling process. The copied sheets are, thereafter, guided to the discharge tray to continue on copying operation.

The present invention is directed to an image forming apparatus comprising, a copying machine including a plurality of developing units, and having a simultaneous multicolor copying mode for obtaining a multicolor copy by switching developing colors during one scanning operation, and an interrupt function for effecting interrupt copying, whereby when the simultaneous multicolor copying mode is executed, the interrupt copying is prohibited to prevent miscopying caused by interrupt copying at the simultaneous multicolor copying.
摘要:
An image duplicating apparatus having a document table for supporting a document sheet thereon divides an image area of the document into two sections and successively duplicates the respective images of the two sections onto two separate copy surfaces. Switches specify the ratio by which an image on the document sheet is to be magnified or reduced for. An image magnification/reduction lens unit responds to the switches for altering a currently established magnification or reduction ratio to the newly specified ratio of magnification or reduction. A control circuit controls the duplicating means so that, when the magnification or reduction ratio is altered prior to termination of the duplication of a first one of the two sections, a second one of the two sections is copied in the altered magnification or reduction ratio.
摘要:
A copying machine having an original feeding unit for feeding originals onto a platen glass which is operable in a two-original feeding mode where two originals are placed side by side in a particular position on the platen glass, and a sheet handling unit which is operable in a binding mode where copy sheets which copied images are bound. When the two-original feeding mode is selected, a selection of the binding mode is inhibited. When the two-original feeding mode is selected after the binding mode was selected, a warning is generated to inform that the sheet handling unit becomes impossible to be operated in the binding mode. When a copying operation is started without in spite of the generation of the warning, the binding mode is canceled.
摘要:
An image duplicating apparatus including a device for designating a localized area of a document sheet bearing visible images, a first input for entering conditions relating to the formation of the images within the designated area, a second input for entering conditions relating to the formation of the images outside the designated area, and image reproducing sections capable of duplicating the images on the whole area of the document sheet onto a single face of a copying sheet, wherein the images within the designated area of the document are duplicated onto the single face of the copying sheet in accordance with the conditions entered by the first input and the images outside the designated area of the document are duplicated onto the single face of the copying sheet in accordance with the conditions entered by the second input.
摘要:
A scan-mode changeable image duplicating apparatus having operational parameters and modes of operation and operative to duplicate a document in accordance with selected ones of the operational parameters and modes of operation, including a recirculating document feeder unit having a document storage tray and a passageway through which a document is to be withdrawn from the tray and returned to the tray by way of an exposure position in which the document is to be scanned, a scanning unit for scanning a document in the exposure position, the scanning unit being movable back and forth with respect to the exposure position, a control system for controlling the document feeder unit and the scanning unit to operate either in a scanner-moved scanning mode in which the scanning unit is driven to move with respect to the exposure position to scan a document fixedly held in the exposure position and a document-moved scanning mode in which the scanning unit is fixed with respect to the exposure position and scans a document being moved with respect to the exposure position, and keys for entering desired ones of the operational parameters and the modes of operation for automatically selecting the scanning mode in which the control system is to control the document feeder unit and the scanning unit.
