A first microprocessor controls the operation of a document conveying device, and a second microprocessor controls the operation of a copying device. A third microprocessor connected to the first and second microprocessors monitors the operation state of each of the first and second microprocessors. When an abnormality occurs in one of the first and second microprocessors, the third microprocessor determines an image forming operation controllable only by the other microprocessor. The third microprocessor makes the other microprocessor execute the determined image forming operation.

Image forming apparatus with improved monitoring system for operation of microprocessor controlling image forming operation

A solid state image sensing device having a semiconductor substrate, a first diffusion region of a positive or negative conductive type provided on the semiconductor substrate, a plurality of second diffusion regions each of which is an opposite conductive type relative to the first diffusion region and is provided in the first diffusion region, and a semiconductor thin layer provided on at least the second diffusion regions.

Solid state image sensing device

A program replacement device is incorporated in a computer system having a CPU and a program memory in which first programs to be executed by the CPU are stored. The program replacement device includes a RAM employed as the program memory and having a write enable terminal, and a protection circuit interposed between the write enable terminal of the program memory and a write signal outputted from the CPU. The protection circuit includes a push switch for instructing program replacement with respect to the program memory, a pulse generating circuit for generating a pulse signal having a given time interval in response to an instruction from the push switch, and a gate circuit for making, only when the pulse signal is generated, the write signal outputted from the CPU valid with respect to the write enable terminal of the program memory. The program replacement device further includes an interruption generating circuit for generating in the CPU an interruption required to write second programs in the program memory in response to the instruction from the instruction section, thereby replacing the first programs by the second programs.

Computer apparatus and method for replacing programs between memories by

An image forming apparatus includes a feeder for feeding a new paper accommodated in a feeding cassette, an image forming device which forms an image on the paper fed by the feeder, an intermediate container which temporarily accommodates the paper fed by the feeder and having the image thereon, a refeeder which refeeds the accommodated paper from the intermediate container to form an image on the paper again, a detector which detects presence or absence of paper to be fed by the refeeder for image formation, and a controller which effects a change-over from the paper feeding operation by the refeeder to the paper feeding operation by the feeder when the detector detects the absence of paper to be refed or forbids the paper feeding operation by the refeeder until the detector detects the absence of paper to be refed after the paper has been accommodated in the intermediate container.

Image forming apparatus for producing duplex or composite prints with

A control circuit changes a sorting mode of a sorter corresponding to a state whether an original is both-sided or not, or whether or not a plurality of originals are simultaneously reproduced in one round of copying process when images of a plurality of originals are distributively reproduced on the same side of a transfer sheet, or whether a mode of the number of sheets of original and copy mode are for both sides mode or composite mode. With such a control, a sorting mode process is prohibited when a required transfer sheet is one irrespective of whether the number of sheets of original is one or not.

Copying apparatus which can prohibit the sorting process

A copying machine has an automatic document handling device including a document tray, first transport member for feeding original documents placed on said document tray to a predetermined position located between said document tray and an image reading position, second transport member for further feeding original documents fed to the predetermined position by the first transport member to the image reading position, a sensor detecting means for detecting the presence of original documents placed on the document tray and feeding member for feeding a copy paper to a fixed position within a copy paper feeding path before the original document is fed to the image reading position by the second transport member. When the presence of said third original document disposed on the document tray is detected by said sensor after a second original document has been fed from said document tray to the predetermined position via said first transport member during the copying operation for a first original document fed to the image reading position via said second transport member, the feeding member feeds the copy paper corresponding to a third original document.
