  • Patent number: 5575544
    Abstract: An anti-theft apparatus for use in a vehicle-mounted electronic component includes a removable control panel. Protrusions on a first side of the control panel engage holes in a first side of an equipment body of the electronic component and function as hinges as the control panel is rotated to a mounted position. A first electrical connector on the equipment body engages a second electrical connector on a rear surface of the control panel and a biasing member exerts a force against the rear surface of the control panel. The control panel includes a recess in a second side into which a locking protrusion of a locking mechanism in the equipment body extends. A button actuates the locking mechanism retracting the locking protrusion and allowing the biasing member to eject the control panel from the equipment body. The locking protrusion is retracted by a sliding cam or directly by depression of the button.

  • Patent number: 5449228
    Abstract: When an operating unit (10) of a vehicle-mounted electronic equipment is attached to its equipment body (20), a first engaging portion (18) and a second engaging portion (24) of engaging means are engaged and the operating unit is turned around the engaging means in a direction in which the operating unit contacts the equipment body substantially completely. In this case, a releasing member (11) moves a locking member (4) to a releasing position. Under such situation, a locking portion (7) of the operating unit and a locking portion (6) of the equipment body are aligned in position. The locking member (4) is then turned to a locking position where the locking means is locked to thereby complete the attachment of the operating unit to the equipment body.

  • Patent number: 5097392
    Abstract: A controller mounting structure for a controller which can be removed from a front panel of the structure when the structure is not being used. The panel has a mounting port for the controller, and a first connecting terminal means arranged inside of the mounting port. A second connecting terminal means which connects with the first connecting terminal means is arranged within the controller. The mounting port has a terminal protecting element which protects the first connecting terminal means when the controller is removed. The terminal protecting element is forced toward the controller by an urging member. When the controller is being mounted on the mounting port, the terminal protecting element pushes the controller and the terminal protecting element acts as a damper for the shock of mounting operation.
