    摘要: A communication apparatus is provided with an element for reading out information signals recorded on a medium. The reading element includes a reproducing portion for reproducing the signals recorded on the medium and a processing portion to process the reproduced signals. The information signals are temporarily stored and sequentially transmitted. Electric power to the reading means is controlled when the information is transmitted through a communication line.

    摘要: An image transmitting apparatus for digitizing a still-picture television signal, a manuscript image signal or the like and transmitting the digitized signal over a line is adapted to read an analog image signal stored in video memory such as a video disk, convert the read analog image signal into a digitized multi-valued signal and store the multi-valued image signal in an image memory. On the basis of paper size on which printing is to be performed by an apparatus, such as a facsimile machine, on the receiving side, the number of pixels constituting the multi-valued image signal stored in the image memory and an ensuing binary coding method, a ratio is obtained at which the multi-valued image signal stored in the image memory is to be expanded or compressed, and the multi-valued image signal is expanded or compressed based on this ratio. The multi-valued image signal thus expanded or compressed is binary coded as by a dither method, and the binary-coded image data are transmitted to the facsimile machine on the receiving side through a line.

    摘要: There is provided a portable storage device which makes it possible to largely reduce time that is taken to remove the storage cartridge that is inserted and cannot be handled. A removable hard disk cartridge contains a hard disk and a control circuit for control of writing and reading of data in and from the hard disk in a casing thereof. A main unit includes an automatic loading/ejecting mechanism that receives the hard disk cartridge into a predetermined inner position within the main unit and ejects the same out from the position, and a microprocessor that controls storage operation for storing data in the hard disk cartridge. Before the automatic loading/ejecting mechanism performs a receiving operation, it is determined whether access to contents recorded on the hard disk can be gained, and when the access cannot be gained, the receiving operation by the automatic loading/ejecting mechanism is inhibited.

    摘要: A signal processing device detects information drop-out parts of an incoming information signal by dividing the information signal received for a given period of time into an n number (n: an integer which is at least 2) of blocks and by forming an information drop-out part signal indicating a part that has an information drop-out within each of the blocks. The device is thus arranged to be capable of promptly finding the parts of the information signal having information drop-outs.
