Abstract: A packet-switched facsimile network and method of operation, wherein the network includes a plurality of facsimile stations, and a plurality of nodes for connecting the facsimile stations. The network includes subscribers' transmission channels, such as telephone switched network, for connection to the facsimile stations, and common transmission channels, such as dedicated lines and packet switched network, for connection to the nodes, in order to allow the facsimile stations to communicate with each other. In operation, the part of image data received from a plurality of facsimile stations is formed into data packets at the nodes. Simultaneously, the formed data packets are sent via the common transmission channels to destination nodes, and therefrom to appropriate receiving facsimile stations. It is possible that during transmission, the destination node may transmit image data contained in one data packet, while it has not received the next data packet that contains image data to be sent subsequently, which could cause transmission error. As a result, the destination node selectively inserts fill codes into the image data. In the preferred embodiment, the facsimile network is a packet switching Group 3 facsimile network and the G3 machines can communicate with each other point-to-point, via the packet-switched facsimile network.

Abstract: Digital data produced by a document scanner or other data source is sequentially stored in a memory. A remote data receiver generates requests for data causing communication of the data from the memory in the same sequence in which it was stored but at a rate substantially asynchronous with respect to the rate of scanner data production. Data is concurrently loaded into the memory and transferred from the memory to the receiver so that continuous data storage and transfer throughout the scan of a given image is possible. Data from the scanner is sequentially loaded into the memory in recycling sequences until there are no available memory storage sections. The scanner is then caused to stop scanning and to cease data production until transfer of data occurs from a memory storage section to the remote receiver. The scanner is thereafter enabled so as to resume with production of the next data following that which was last loaded into the memory. For a scanner, the data interruption and resumption is obtained by stopping and repositioning of the scanner bar relative to the document. Scanning is started or restarted when the data in the memory is inadequate to completely satisfy the current receive command.

Abstract translation: 由文件扫描器或其他数据源产生的数字数据被顺序存储在存储器中。 远程数据接收器产生对数据的请求，该数据导致来自存储器的数据以与存储器相同的顺序进行通信，但是以相对于扫描器数据生成速率基本上异步的速率。 数据被同时加载到存储器中并从存储器传送到接收器，使得在给定图像的整个扫描中的连续数据存储和传送是可能的。 来自扫描仪的数据以循环序列顺序加载到存储器中，直到没有可用的存储器存储部分。 然后使扫描仪停止扫描并停止数据生成，直到数据从存储器存储部分发送到远程接收器。 之后启用扫描仪，以便随着最后加载到存储器中的下一个数据的产生继续生效。 对于扫描仪，通过停止和重新定位扫描器条相对于文档来获得数据中断和恢复。 当存储器中的数据不足以完全满足当前接收命令时，启动或重新启动扫描。

Abstract: An image copying apparatus for copying an original by scanning a print head having a predetermined head print width a plurality of times in a main scanning direction and displacing an object to be recorded in a subscanning direction, thereby forming an image of the original on the object, includes circuitry for calculating a print width formed at a last line, and for displacing the calculated printed width before the last line and for reducing a suction area of the object on a platen at the time of printing of the last line. The copying apparatus includes a continuous rolled sheet supply and cutter and a stacked pre-cut sheet supply, both sheet supplies have a conveyor for feeding the respective sheet to a recording area. Recording is performed on the inside surface of the rolled sheet and on the lower surface of the cut sheet to avoid the problem of dust collecting on the opposing surfaces.

Abstract: A printing control system for a facsimile receiver of the type having a printhead which scans across the page and prints multiple lines of the facsimile image simultaneously. The system includes a first in-first out memory for storing incoming facsimile data which arrives more rapidly than the printing system can accommodate. The stored incoming data is transferred to one or more scan buffers as needed, and then sequentially to the printhead drivers.

Abstract: An original table is provided on which an original is placed. This original on the original table is scanned by a first optical unit. A conveyance path, constituting an auto document feeder, is provided near the table, and one side of the original moving on the conveyance path is scanned by the first optical unit and the other side of the original is scanned by a second optical unit disposed near the first optical unit. The scanned output of the first optical unit is stored in a memory which can delay its content by a time corresponding to the distance between the first and second optical units. The signal stored in this memory and the scanned output of the second optical unit are sequentially outputted.

Abstract: An image communication apparatus comprises: reader for reading an image on an original and converting to an electrical signal; a memory for storing the image data corresponding to the electrical signal; a detector for detecting that an unused memory area in the memory becomes a predetermined amount; an interrupter for interrupting the operations of the memory and reading means in response to a detection output from the detector; a transmitter for transmitting the image data stored in the memory; and a control unit for allowing the operations of the reader and memory to be restarted after the transmission by the transmitter from the location where the operation of the reader was interrupted or from a location before the above interrupted location. This apparatus can certainly perform the image communication using a memory of a small capacity. In case of transmitting and receiving an original longer than a standard size, the recording sheets after the reception can be easily connected and reproduced.

Abstract: An image forming apparatus capable of accurate recording of input image information through a real-time image processing. It is also capable of simultaneously driving plural recording units, and of avoiding distortion in the recorded image even when the recording unit is not synchronized with the input information. These features are attained by the use of plural memories successively selected for image signal recording and for signal read-out, wherein at least one of the memories has no access while others are used for signal write-in and read-out.

Abstract: A laser recording method in which recording is made on the recording medium by using the laser light modulated corresponding to the original to be recorded. The original to be recorded is line read out at a predetermined clock frequency in the main scanning direction of the original reading out device having a photoelectric conversion element. The read out signal of the original reading out device is sent to a memory capable of storing at least the signals belonging to the line now being read out and the signals belonging to the immediately preceding line. The signals belonging to the line immediately preceding the line being read out are read out from the memory to accomplish laser modulation and are then recorded on the recording medium.
