  • Patent number: 6590177
    Abstract: A pressure sensitive sensor is composed of a pair of upper and lower electrodes sheets 1 and 2 disposed oppositely, a spacer 3 interposed between both of the sheets 1 and 2, and adhesives 4 and 5 between these electrode sheets 1 and 2 and spacer 3. In the spacer 3, a hole 31 is formed in a position of a contact portion 6. A diameter of this hole 31, convex portions 13 and a pressure sensitive electrode 22 are set in such a positional relationship that a peripheral portion of the hole 31 is overlapped between the convex portions 13 and the pressure sensitive electrode 22. Then, the adhesives 4 and 5 open more largely than the diameter of the hole 31 of the spacer 3 so as to be removed from the peripheral portion of the hole 31 on both surfaces of the spacer 3.

  • Patent number: 5739920
    Abstract: An image processing apparatus which improves data compression efficiency and reduces communication time. If the number of colors of information included in an original image is small, i.e., if an original image is an image including one or two fundamental colors of a color system on white ground, the apparatus transmits only the corresponding color component data. Further, the transmission is made in accordance with a recording order which the receiving side notifies to the transmitting side. As a result, time from reception of the image information to the end of recording can be reduced.

  • Patent number: 5726777
    Abstract: An image transmitting apparatus includes a transmitter capable of transmitting color image information and a memory that stores addresses of a plurality of receiving sides together with respective information indicating, for each stored address, whether the corresponding receiving side has or does not have a color receiving function. The apparatus designates a plurality of destinations from among the plurality of receiving sides whose addresses are stored in the memory and discriminates whether or not each of the designated destinations has the color receiving function in accordance with the information stored in the memory. The apparatus then notifies that at least one of the destinations does not have the color receiving function, in response to the discrimination.

  • Patent number: 5696598
    Abstract: A facsimile apparatus comprises discriminating means for discriminating whether a sending image is a color information or not. The apparatus transmits a color information in the transmitting mode corresponding to the discrimination provided by the foregoing discriminating means subsequent to sending to a receiver at a destination in advance the page information determined by the foregoing discriminating means as having a color information when the receiver at the destination has a color receiving function, and transmits all the page information as monochromic information when the receiver at the destination does not have any color receiving function.

  • Patent number: 5684604
    Abstract: Efficient image transmission is performed upon determining, based upon information sent from a receiving side at the time of negotiation, whether the apparatus on the receiving side is capable of progressive build-up, pseudo-progressive build-up in stripe units, sequential build-up or more than one of these build-up methods. Examples of the information sent from the receiving side include an instruction entered on the receiving side, the type of printer, the stripe width if the printer is capable of stripe printing, the communication speed and the memory capacity, etc. It is possible to use information from a line or network as well. This arrangement makes it possible to transmit image data that has been coded efficiently. Outstanding effects are obtained in multiple-address communication.

  • Patent number: 5677772
    Abstract: An image processing apparatus whereby a user is able to perform an appropriate operation easily and without mistakes on the basis of guidance images related to the operation of the apparatus. Images related to operation guidance of the apparatus are input by a CCD line sensor and a reading motor beforehand and stored in a RAM. The user manipulates keys so that a guidance image necessary for an operation from among images related to operation guidance of the apparatus stored in the RAM is displayed on a display device.

  • Patent number: 5650861
    Abstract: A color image processing apparatus and method through which it is possible to realize high-speed encoding processing of image data containing data indicative of blank spaces. When encoding processing is executed, a CPU sets data, which is added on as a blank space or margin, in a blank-value setting memory, and a DSP for encoding processing reads in the set value before the start of encoding processing, effects a transformation of the color space to undergo encoding processing, and stores the resulting data in its own internal memory, whereby the data stored in the internal memory is used in encoding of blank areas to make possible high-speed encoding processing.

  • Patent number: 5502574
    Abstract: In a facsimile apparatus which can be connected to a data processing apparatus for transmitting/receiving a digital signal, when a specific pattern which is to overlap two or more lines of print without a space between the lines is to be output, a pattern is developed so that the patterns in the upper and lower lines are made continuous with each other. When characters of various fonts are to be mixed, arbitrary patterns from another apparatus can be registered in the facsimile apparatus with arbitrary codes in addition to an output operation using patterns corresponding to codes registered in advance in the facsimile apparatus. For this reason, any codes can be output during an output operation of one page, and various patterns can be mixed.

  • Patent number: 5287402
    Abstract: There is disclosed a facsimile apparatus which transmits a predetermined signal, such as CNG signal, during pause periods succeeding the transmission of telephone number signals. This operation prevents the delay of CNG signal detection in case the receiving side has an automatic telephone/facsimile switching function, and also prevents the facsimile communication being erroneously cut off in case the pause period of the calling side eventually overlaps with the CNG detection period of the receiving side.
