  • Patent number: 6731350
    Abstract: In the structure of a vehicle-mounted display system, a pair of racks, that is, a first rack and a second rack, are secured to a sliding chassis which can move forward and backward inside a case. A pair of arms, that is, a first arm and a second arm, are swingably supported by a movable base which rotatably supports a monitor, with a third motor serving as a driving source of the monitor being disposed between the pair of arms. A first gear that engages the first rack and a first motor serving as a driving source of the first gear are installed on the first arm. A second gear which engages the second rack and a second motor serving as a driving source of the second gear are installed on the second arm. When the monitor is drawn in and out, both motors are operated in order to move both gears along their corresponding racks in the same direction, as a result of which the movable base is moved forward and backward.

  • Patent number: 6711003
    Abstract: In a monitor device wherein a display member is pivotably supported in a ceiling portion of a vehicle, there is a risk that the display member may slide down due to vibrations during vehicular running or due to its own weight. In the monitor device of the invention, a stowing recess 11 is formed in a receptacle member 10, and a display member 2 and a support member 5 are disposed within the stowing recess 11. A retaining member 12 for restricting a distal end 2a of the display member 2 is formed at an opening edge of the stowing recess 11. When the display member 2 is stowed, it moves in the Y1 direction and its pivotal movement in a downward direction is prevented by the retaining member 12. When the display member 2 is to be moved in an opening direction, it is moved in the Y2 direction and is thereby disengaged from the retaining member 12; thereafter the display member 2 is rotated downward.

  • Patent number: 5303062
    Abstract: A camcorder (1) has a VCR portion (2) including a video tape drive (2a), and a camera portion (3) including a lens block (4). The VCR portion and camera portion are rotatably connected (11) for movement to a configuration convenient for photographing (FIG. 2 ) and to a compact configuration convenient for carrying (FIG. 1 ). A switch (1010) switches between a camera mode in the photographing configuration and a VCR mode in the carrying configuration. In the camera mode, the VCR portion records video signals from the lens block on the video tape and, in a VCR operation mode, the VCR portion only plays back previously recorded video tapes. The switch is mounted within one of the VCR and camera portions such that the switch is not accessible from the outside. During rotation, a linkage (100) moves a lens cover (12) between lens covering and exposing positions.

  • Patent number: 5278701
    Abstract: A video camera combined with VCR comprises a camera unit for imaging an object and producing a video signal representing an image of the object, and a video signal recording unit including a supply reel base, a take-up reel base, and a cylinder assembly made up of a fixed cylinder and a rotatable cylinder having a magnetic head built therein for recording the video signal on magnetic tape. The cylinder assembly is positioned in a direction longitudinally outward of a reel hub with respect to the other reel hub of a tape cassette loaded in the video signal recording unit. The camera unit is positioned toward the object in front of the video signal recording unit.

  • Patent number: 5130741
    Abstract: A DC power source light which is mountable to and dismountable from a camera body of a video camera is supplied with power from a battery provided in said camera body so that said DC power source light is made compact and light in weight. Further, either said camera body or said DC power source light has a unit for preventing excess discharge of said battery and a unit for preventing excess current when the switch is turned on, thereby to protect said battery.

  • Patent number: 4894731
    Abstract: In a camera integrated with a VTR, a hotographing method by use of a self timer is disclosed. This method comprises the steps of: setting a recording standby state; supplying to a display section a repetitive signal for allowing the display section to be alternately repetitively lit on and off by operating a self timer operating element; supplying a light-on signal to the display section when a predetermined time has passed to thereby light on the display section, supplying an operation signal to the VTR section, cancelling the camera recording standby state, and thereby starting a recording; and stopping the supply of the light-on signal to the display section after the elapse of a predetermined time after the recording was started to thereby light off the display section, stopping the supply of the operation signal to the display section, and thereby returning to the camera recording standby state.
