摘要:
An image density reading apparatus in which an image of a document is irradiated by a light source and a density signal is generated from an image light reflected from the image. In the apparatus, there is an amplifier for amplifying a density signal on the basis of an amplifying gain and a signal processor for processing the amplified density signal in accordance with a predetermined processing algorithm to output a gain control signal. The amplifier is provided with a switch for changing a gain in response to the gain control signal.

The invention provides an image forming apparatus capable of performing an ordinary copy mode, whereby the entire surface of a document is scanned by an image reader to copy the entire surface on a copy sheet, and a serial page copy mode, whereby first and second half portions of the document are separately scanned to copy each half portion on a separate copy sheet. In the apparatus, copy sheets of different sizes are fed from a plurality of cassettes each storing a copy sheet of a predetermined size or a manual feed tray. There is provided a memory for memorizing a serial copy sheet size to be fed from the manual feed tray. When the serial page copy mode is selected in the manual feed mode, the image reader is controlled to separately scan the first and second half portions of the document on the basis of the serial copy sheet size.

A temperature controller wherein breakage of a thermistor whose resistance decreases with increase in temperature of a member to be heated is detected by watching whether a voltage dependent upon the resistance of the thermistor is increased or not after a predetermined period of time. A heater for heating the member is turned off when the breakage of the thermistor is detected.

A copying system includes a plurality of copying apparatuses, a communication line interconnecting the plurality of copying apparatuses with each other such that the plurality of copying apparatuses can communicate image data therebetween, and a controller. The controller controls the copying system such that: (i) several or all of the plurality of copying apparatuses produce copying materials in parallel according to image data read by one of the plurality of copying apparatuses, and (ii) at least one of the several or all of the plurality of copying apparatuses receive image data of a next job while a present job is being conducted.

An image recording apparatus, such as a copier or a printer which is capable of connecting with another recording apparatus, includes: a memory for storing image data corresponding to plural document pages; a mode selector for selecting one of a master mode in which the image data, stored in the memory, are transferred to the other image recording apparatus, and a slave mode in which the image recording apparatus receives image data transmitted from the other image recording apparatus; and a transmission/receiving controller for controlling transmitting and receiving of the image data according to the selection of one of the master and the slave modes. In the apparatus, the image data transmitted from the other image recording apparatus are stored in the memory and the image corresponding to the image data stored in memory is recorded on a recording paper. The recording operation is independent from an operation of the other image recording apparatus when the slave mode is selected.

An image forming apparatus that sets an output unit configured by a plurality of pages of which the order is determined as one copy and outputs the a plurality of copies of output units as a JOB includes an image forming unit that sequentially forms images corresponding to the plurality of pages on a plurality of sheets, a control unit that performs a calculation process of image eigenvalues based on the images for each of output units, a first storage unit storing a result of the calculation process performed for a reference copy of the output unit that is a specific one copy out of the plurality of copies of the output units, and a second storage unit storing a result of the calculation process performed for a copy of the output unit other than the reference copy out of the plurality of copies of the output units.
摘要:
Disclosed is an image forming system, in which the printer controller is capable of performing the re-RIP (Regeneration Raster Image Processing) in conformity with the revised page order accepted from the image forming apparatus. When determining that the re-RIP is necessary, the image forming apparatus transmits a regeneration request including revised page order information, changed from the original page order, to the printer controller. Receiving the regeneration request, the printer controller reapplies the rasterization processing to the print data while using the data stored in advance in the storage section, to regenerate the revised image data corresponding to the page information, and then, transmits the revised image data to the image forming apparatus. Receiving the revised image data regenerated in response to the regeneration request, from the printer controller, the image forming apparatus employs the revised image data for performing the image forming operation in regard to the print job.
