There is disclosed an image recording apparatus having reader for photoelectrically reading an original and generating image information, a first transmitter for transmitting the image information from said reader, after compressing treatment, to an outside apparatus, a second transmitter for transmitting the image information from said reader without compressing treatment to an outside apparatus, and selecter for selecting either said first or second transmitters according to the destination of said image information.

Image processing apparatus

An image processing system comprises a printer and a reader which are mechanically and functionally separated in such a manner that they can be used independently of each other and the transmission of image information is possible therebetween. Said reader includes an operating unit which cooperates with the printer to perform many functions such as the image operating function, the image transfer function, the presetting function and the image quality processing function, in addition to a function of a conventional copier. Said operating unit consists of a general purpose key portion; a soft key portion which is used for optionally creating the copy transfer functions and having function keys and displays corresponding to said keys, said displays being adapted to display key labels and messages to a user in cooperation with a driver, CPU and controller; and a function key preset key portion which is used for registering, reading and resetting the image transfer functions and having a standard mode return key, preset keys and preset key displays corresponding to said reset keys and adapted to display the reset position.

Image processing system

An image processing system of the invention has a reader which reads out an image of an original, a page memory which stores image information of the original in the form of electric signals, a disk memory which stores part or all of the image information in the disk memory and also stores image processing information, an image processing section, a digitizer for the operator to input the image processing information, a CRT which displays input information or corrections in convesation language, a DMA controller, and a printer. The image processing system of the invention is capable of DMA transfer without the intermediacy of a CPU. Fewer addresses are required for readout of the image information from the memory, and high speed image processing is achieved.

A specified original that is not supposed to be copied is marked with a pattern that is formed by infrared reflected light. A copying apparatus includes a detecting unit for detecting the pattern and determines that an original is the specified original in accordance with the detection by the detecting unit. A copying operation is controlled in accordance with the determination of whether the original is the specified original that is not supposed to be copied.

Image processing apparatus having means for detecting non-visible light,

A printing or copying apparatus of a type provided with a recording medium, operable device for forming an image on the recording medium, device for operating a first signal required for the timing operation of the operable device, keys for instructing to start or stop the execution of image formation, first control device controlling the operable device in accordance with the first signal, and which comprises a memory for storing a program for operation control of the operable device for image formation, and second control device for controlling the first control device in accordance with the key instructing device for controlling the execution of image formation and for controlling at least one of the operable devices, and which comprises a memory for storing a program for operation control of the first control device.

Image forming device

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.

Image forming apparatus having start and stop keys integrally connected

An image processing system comprises a printer and a reader which are mechanically and functionally separated in such a manner that they can be used independently of each other and the transmission of image information is possible therebetween. The reader includes an operating unit which cooperates with the printer to perform many functions such as the image operating function, the image transfer function, the presetting function and the image quality processing function, in addition to a function of a conventional copier. The operating unit consists of a general purpose key portion; a soft key portion which is used for optionally creating the copy transfer functions and having function keys and displays corresponding to the keys, the displays being adapted to display key labels and messages to a user in cooperation with a driver, CPU and controller; and a function key preset key portion which is used for registering, reading and resetting the image transfer functions and having a standard mode return key, preset keys and preset key displays corresponding to the reset keys and adapted to display the reset position.

Image processing apparatus with apparatus for adjusting a magnification

This invention provides an image processing system comprising devices for producing image signals by scanning an original image, process units for generating video signals by processing the image signals, detector for detecting the coordinates of the original image and controller for storing the coordinate signals from the detecting means and for controlling the process units according to thus stored signals.

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.
