Abstract: An image data encoding/decoding device has a memory for parallel data input/output, a data input unit, a data output unit, an encoding unit, a decoding unit, and a memory control unit. Separate encoding and decoding units are employed to ensure efficient encoding/decoding operations. The image data are handled in serial form in the input, output, encoding and decoding units and in parallel form only at the input to or output from the memory, so that these units can effect simultaneous parallel functions in mutually independent manner. Also, efficient access to the memory is ensured by the memory control unit, which handles simultaneous requests for access from various units according to a predetermined order of priority.

Abstract: An image data processing apparatus has: a reading portion for reading an image of an original and outputting the image data thereon, an encoding portion for encoding the image data which has been output from the reading portion, an image memory for storing the encoded data which has been output from the encoding means, and a DMA control portion for DMA transferring the encoded data which has been output from the encoding portion to the image memory. The DMA control portion successively selects a plurality of DMA channels, and DMA transfers the encoded data using a selected DMA channel.

Abstract: A data conversion method and an apparatus for the same which converts undefined-length image signal coded by a MH or MR method for facsimile equipment, etc. into fixed-length data. Coded undefined-length image data is inputted, and, in accordance with a bit length contained in the image data and with the number of the effective bits in the last byte, bits to be outputted from a barrel shifter are shifted. Control is performed to byte pack the bits of the last byte and the shifted bits outputted from the barrel shifter, and coded data is converted into data in byte units, thereby enabling high-speed byte packing.

Abstract: An image formation apparatus having an original feeding plate for retaining a supply of originals, a take-out roller for taking out the originals sheet by sheet, a copying device for forming on sheets an image corresponding to the image information of the original taken out by the take-out roller, a plurality of bins for receiving the sheets having images formed by the copying device, a reversing unit which can selectively reverse the stacking order of the image receiving sheets, and a guide unit which distributes to bins the sheet whose direction of the surface has been converted by the reversing unit.

Abstract: An original scanning apparatus comprises a housing having an original placing platen for placement of an original, an optical system for scanning an original on the original placing platen to obtain information corresponding to the original, a cover for covering the original on the original placing platen, a scale for designating the size of the original provided at one side of the original placing platen, an automatic sheet feeding mechanism provided separately from the cover for feeding the original through the scale between the original placing platen and the cover, and a sheet exhausting mechanism for feeding the scanned original from the original placing platen through the scale out of the original placing platen.

Abstract: In an electronic copying machine, a picture on an original is optically scanned by an optical system including a first carriage provided with an exposure lamp. An image obtained by the optical system is formed on the surface of a tubular-shaped photoconductive drum rotating in a predetermined direction. Additional pictorial information such as a date or a telephone number, which is not included on the original picture, is written at a desired location on the original image. Such additional information is entered into the copying machine from an operational panel of the machine. The light from the optical system led to the drum is partially shut off by a shutter. A character generator generates pattern data corresponding to the entered additional information, the pattern data being written in at the location on the drum surface which is shielded from the incident light by the shutter. A write unit is used for the writing of the pattern data.

Abstract: An image forming apparatus includes a main body having an original table surface on which an original is to be placed, and an automatic original feeder. The feeder has an original cover located to oppose the original table surface and vertically movable between a lower position where the original cover contacts with the original table surface and an upper portiion where the original cover is separated from the original table surface. When an original is to be fed between the table surface and the original cover or discharged from between the table surface and the original cover by a feeding mechanism, the original cover is moved to its upper position. When the original on the table surface is to be scanned by an exposing device in the main body, the original cover is moved to its lower position so as to press the original against the table surface.

Abstract: An image reading apparatus has a photo line sensor, a motor, buffers, a memory, a process unit, and a CPU. A facsimile system has such an apparatus, a transfer section and a modem. Image datas of an original is read out during displacement of the original to allow reliable, fast image processing.

Abstract: This invention relates to a tape protecting cover of a video tape cartridge, especially to a shaft having a groove the shaft being formed integrally with the tape protecting cover. A first and second molds 12 and 14 divided by the parting line 20 have dents 16 and 18 respectively to form a space when both molds are joined. The dent 16 of the first mold 12 is provided with a rectangular pin 22 for forming a groove so that its one end surface 22a may abut to the end wall surface 16a of the dent 16. The front side 22b of the rectangular pin 22 extends so as to extrude to the dent 18 of the mold 14, and is constructed to form an inclined surface 22c between the end surface 22a of the rectangular pin 22 and itself. The end wall surface 18a of the dent 18 of the second metallic mold 14 is formed to have a same inclined angle .theta. as the rectangular pin so as to abut to the inclined surface 22c of the rectangular pin 22 when both metallic molds are joined.

Abstract: A facsimile transmission system which comprises steps of recognizing, at a signal transmission side, a minimum transmission time at a signal receiving side and a capacity of a buffer memory for temporarily storing there in received data; transmitting image data in a plurality of lines of the image original which can be stored in the buffer memory and comparing the total sum of the minimum transmission time in the plurality of lines with a time required for the transmission, and transmitting a full bit, only when the time required for the signal transmission is short.

Abstract: A display device according to the present invention is incorporated into an electrical machine in order to display the operating condition of the electrical machine. The electrical machine has movable parts such as doors to be opened by an operator when the electrical machine stops operating due to a malfunction. This display device schematically shows, by means of display elements, the positions of the movable parts before and after the operator moves them, and displays the elements in accordance with the condition of the electrical machine. Upon the occurrence of a malfunction in the electrical machine, the display elements on the schematic display corresponding to the faulty machine part can be displayed so as to be understood by the operator.

Abstract: This invention discloses a thermal recording apparatus which is capable of providing satisfactory image quality through the control of recording pulses supplied to a thermal head, also capable of obtaining uniform recording density through the control of pulse width or voltage of recording pulses according to the level of black color of the image information, and further capable of avoiding unnatural change in the recording density within a recording sheet by conducting the control of pulse width of the recording pulses at the start or at the end of each recording operation corresponding to an original sheet.
