Abstract: An image forming apparatus includes an image forming mechanism for forming an image and a matrix circuit having connected thereto a plurality of keys including an initiating key for instructing the start of image formation and a stop key for interrupting image formation. The image forming apparatus further includes a controller for controlling image formation by the image forming mechanism in accordance with a control sequence and a memory containing a program for sensing key input of the matrix circuit. Prior to the start of image formation, the controller executes the program for sensing key input of the matrix circuit and executes the control sequence in response to the sensing input of the initiating key. During image formation, the controller executes the program for sensing key input of the matrix circuit such that sensing whether the stop key has been input is executed without sensing whether the initiating key has been input.

Abstract: A document scanning apparatus includes a first scanner for reciprocating an optical member and for exposing an original document put on a document platen, and a second scanner for feeding an original document to an exposure position and for exposing the original document at the exposure position. A selector selects either the first scanner in a stationary exposure mode or the second scanner in a dynamic exposure mode. In the stationary exposure mode, a controller causes forward movement of the reciprocating optical member to stop and the reciprocating member to move backward in accordance with a detection signal signifying that the trailing edge of a recording sheet has passed a predetermined position in the transport path for the recording sheet. In the dynamic exposure mode, the controller controls the second scanner to feed successive original documents in accordance with the same detection signal for the trailing edge of the recording sheet.

Abstract: An image processing apparatus provided with a plurality of operation devices for recording or reproducing an image.

Abstract: An image forming apparatus capable of feeding or transporting recording medium of different sizes through the image forming path. A discriminating device determines whether or not a recording medium has reached a predetermined position in the transport path and a detecting member detects the recording medium a predetermined time thereafter to identify the size of the recording medium. If the recording medium is detected within the predetermined time, it is identified as being of a particular size. When the medium is detected during a time period different from the predetermined time period, the medium is identified as being of a size smaller than the particular size. The image formation operation is controlled as a function of the size identification of the recording medium.
