Abstract: A housing cover structure for a security device includes: a base member made of an optically non-transparent resin; and a window member made of an optically transparent resin. The window member is positioned adjacent to one side of the base member. The window member has: a window body exposed to outside; a first flange extending from the window body on the one side; and a second flange extending from the window body on the other side. The first flange and the second flange are combined within the base member. Each of the first flange and the second flange has a bent shape.

Abstract: An attachment structure for attaching a recess of a housing to a DIN rail includes first and second movable strips. The first movable strip extends continuously from an operable portion and being movable along a surface of the housing in a first direction toward the recess and in a second direction opposite from the first direction. A first claw of the first movable strip and a second claw of the second movable strip move toward the DIN rail in accordance with a movement of the first movable strip in the first direction and engage ledges of the DIN rail. A koma converts the movement of the first movable strip in the first or second direction to a movement of the second movable strip in a direction opposite from the movement direction of the first movable strip.

Abstract: An IC card reader is provided for reading data stored in an IC card with radio communication and inputting the data into, for example, a personal computer. The IC card reader includes a card holder and a fastening mechanism which attaches the card holder to a data reading table detachably. This structure provides for ease of usage of the card reader to a user in two selectable modes. In the first mode, the stored data may be inputted into the computer only by passing the IC card over the data reading table instantaneously. In the second mode, the user may insert the IC card into the card holder fitted on the data reading table to transmit data to the compute through radio communication.
