摘要:
A control system and method for an optical scanner of the type having a document feeding device for transporting documents to an optical scanning station is provided. The control system includes a plurality of buffer memories for temporarily storing optical data from documents processed through the scanning station, and a control circuit connected to the buffer memories and the document feeding device. The delivery rate of the document-feeding device is maximized to a level consistent with an estimated mode value of optical data present on the documents being scanned. When documents having higher than normal optical data cause the buffer memories to fill up faster then than they empty, the control circuit transmits a command to pause or slow down the delivery rate of the document feeding device upon a determination that a threshold capacity of any of the buffer memories has been exceeded or is about to be exceeded. By maximizing the delivery speed of the document-feeding device in accordance with the actual amount of optical data on the documents being scanned, throughput for a given processing bandwidth is maximized.
摘要:
A control device and a method for controlling scanning speed of a scanner. The control device includes a decision device and a driving device. The decision device further includes an image buffer, an up-down counter and a comparator. The decision device receives the input image data and utilizes the up-down counter to compute data access volume inside the image buffer. The comparator decides whether to increase or decrease the scanning speed according to the data access volume and also outputs decision data to the driving device.

A message is displayed on a display unit to indicate that copy reserve is ready even during copying operation. Even during copying, a document placed on a scanning unit (14) can be scanned after the number of copies and the scaling are set from a numerical key pad (16a) and a start key (16d) is pressed. The document is scanned in a scanning unit (14), the image data of which is stored in an image memory (18). As a result, even during copying operation, it is possible to reserve next copy.

An image reading apparatus includes a line sensor for reading an image of an original, a scanning optical system that has a light source and scans the original, a reference reflection member provided in such a position as to reflect a light emitted from the light source, a buffer memory for storing data of the image, an intermittent reading part interrupting and restarting scanning performed by the scanning optical system based on a residual storage capacity of the buffer memory, and a light amount variation correction part correcting a variation in an amount of light of the light source during an interruption of the scanning based on an amount of reflected light from the reference reflection member.

An image forming apparatus is provided to smoothly form images corresponding to received image data even if the memory becomes full when collated printing is executed. If the memory never becomes full during collated printing, images for all of the pages are expanded to intermediate data, stored in a page memory, and complete collated printing is enabled. In the meantime, if the memory becomes full while the print data of part of a page is expanded to intermediate data and stored, the controller, controls so that the page memory can be written after collated printing is executed up to a page immediately before the partial page and the residual pages are printed in the form of collated printing. Therefore, even if the memory becomes full, printing can be executed in a form as close to collated printing as possible.

A peripheral multifunction device includes a CPU performing data transmission and reception between the device and an information processing unit in a multiplex communication mode so that a plurality of functions of the device are performed and a storage unit for storing various data including the data received by the CPU. The CPU further judges a remaining capacity of the storage unit. A processing of storing in the storage unit the data concerning at least one of the functions of the peripheral multifunction device when the judged remaining capacity of the storage unit is at or below a predetermined value.

A facsimile apparatus for outputting multiple copies of a received image comprises a receiver for receiving image data and a protocol signal, a detector for detecting the indication of multiple copy output from the protocol signal received by the receiver, a memory for storing the image data received by the receiver, a recorder for recording the received image data stored in the memory and a control circuit for causing the memory to store the received image data in response to the detection by the detector of the indication of the multiple copy output of the image data and, after the reception, causing the recorder to repetitively record the received image data stored in the memory, in a number of copies equal to that designated by the protocol signal. The control circuit causes the recorder to start the recording of the image data stored in the memory means starting from page 1 and to output one copy of the received image data, when the vacant area of the memory falls below a predetermined level during the reception of the image data.
摘要:
An image data output device for restricting the storage of inputted image data in a memory and successively outputting the inputted image data, when the residual capacity of the memory has reduced to a predetermined value while the image data are being stored in the memory. After the input of the image data has been completed, the image data stored in the memory are read out and outputted.
摘要:
An image forming apparatus includes a scanner for reading image information of an original, a memory for storing the image information of a plurality of originals read by the scanner, a printer for forming the image information of at least two of the originals stored in the memory on a single image formation medium, a detector for detecting that the memory becomes full, and a controller. When the detector detects that the memory becomes full while the scanner is performing a series of read operations, the controller controls the printer to print images of the image information of originals which are stored in the memory and images of which are to be formed on a single sheet, erases the image information whose images are printed, and controls the scanner to restart reading of the originals.
