  • Patent number: 7551220
    Abstract: An image recording/replaying device, such as a video camera, has various operating switches which have enhanced operability so as to suit a mode of use. The image recording/replaying device includes an image display section chat is foldably, unfoldably, and rotatably supported at a body internally incorporating a taking lens. The image recording-replaying device also includes a control switch including an operating key and a plurality of contacts disposed at end portions The control switch further includes direction selection switches which are such that the directions used within the display screen of the image display section corresponding to the directions of the positions of the four end portions of the operating key are changed in accordance with a change in the orientation of the image display section resulting from rotation of the image display section.

  • Patent number: 7310236
    Abstract: A casing that has an electronic component housed therein has a conductive layer made of a mixture of carbon fibers and a thermoplastic resin and an insulating layer where only the thermoplastic resin is exposed on a surface of the conductive layer. The casing prevents leakage of unwanted electromagnetic waves from inside, is not affected by external electromagnetic waves, has small thickness, light weight, high strength and high rigidity, and has excellent contactability with a coating.

  • Publication number: 20040004667
    Abstract: An image recording/replaying device, such as a video camera, has various operating switches which have enhanced operability so as to suit a mode of use. The image recording/replaying device includes an image display section (3) that is foldably, unfoldably, and rotatably supported at a body (2) internally incorporating a taking lens (4). The image recording-replaying device also includes a control switch (14) including an operating key (15) and a plurality of contacts disposed at end portions and an intersection of a cross-shaped portion of the operating key in correspondence with end portions and the central portion of the operating key, in which, by pressing any one of the end portions and the central portion of the operating key, the contact disposed in correspondence with the pressed portion is closed.

  • Patent number: 5822001
    Abstract: A cassette eject mechanism for a recording or reproducing apparatus can remove a cassette eject button from a housing and can reliably eject a tape cassette only when a tape cassette should be loaded or unloaded. A battery loading mechanism for an electronic equipment can make the loading of battery simple and reliable, and becomes easy to handle. The locking mechanism can be simplified in structure so that the number of assembly parts can considerably be reduced. Further, a mechanical chassis supporting mechanism in a recording apparatus is for use with an apparatus in which a mechanical chassis or cabinet can be reduced in thickness. According to this mechanical chassis supporting mechanism, it is possible to prevent an external stress from being applied to the mechanical chassis as a twisting deform force.
