A card-type line interface device is provided with good portability and low-price. The line interface device includes an adapter unit 1 and a card unit 2 for inserting into the card slot of a communication terminal device. The adapter unit 1 has a card connecting connector 11 on a part of the boxlike body, a line connector 12 on another part thereof, and an interface circuit 14. The adapter unit 1 is connected to the card unit 2 in use, and detached from it on carrying. With no troublesome cable, the line interface device can provide good portability. The reduced number of components and reduced number of assembling steps lead to low price.

A shield structure having a plurality of hollow columnar base members arranged with intervals therebetween along the periphery of a section to be shielded on a surface of a circuit board, and a shield cover with a peripheral wall having insertion pieces arranged along the edge thereof at positions corresponding to the positions where the base members are arranged. Each base member has a cut in at least a top surface thereof. The cut forms an elastically deformable tongue portion having a free end at a position where the corresponding insertion piece of the shield cover is inserted. The tongue portion is elastically deformed toward the inner space of the base member by an insertion force applied when the corresponding insertion piece of the shield cover is inserted into the cut at the free end. The tongue portion functions as an elastic holding portion that retains and fixes the shield cover on the base member by applying an elastic resilient force such that the free end thereof presses against the insertion piece of the shield cover.

An antenna body disposed on a housing through a turning shaft in a state in which the antenna body is movable along the turning shaft within an allowable movement range. The antenna body turns on the turning shaft within a range between an upright position to stand on an upper surface of the housing and a flat position to be laid flat. An antenna turning elastic member is provided so as to apply an urging force to the antenna body in a direction in which the antenna body turns to the upright position. One of the antenna body and the housing has a locking projection projecting toward the other, and the other of the antenna structure body and the housing has a locking portion which is fitted to the locking projection when the antenna body is laid flat and which stops the antenna body from turning. When the antenna body moves in a direction in which the antenna body is to be unlocked, the locking projection is released from the locking portion, and the antenna body automatically turns toward the upright position by the urging force of the antenna turning elastic member.

An appearance protective case and an appearance protective case assembly are provided in which damage of a colored or marked pattern due to exposure is prevented, and in which the structure of a formed member having the colored or marked pattern printed thereon is made simple so that the formed member is easily incorporated into the appearance protective case. The appearance protective case includes a sheet-like formed member formed by draw-processing a sheet-like member treated with coloring or marking and a transparent or translucent cover case, and is assembled by fitting the sheet-like formed member into the cover case such that the sheet-like formed member extends in close contact with the inner surface of the cover case.

An interface card includes data transmission routes which allow for data transmission in a plurality of data transmission modes and a mode selection switch for selecting a data transmission mode from the plurality of modes. With the interface card, a user is able to select an optimal data transmission mode for the environment.

A film molded casing includes a transparent or translucent film molded member having a printed layer provided on the inner surface thereof so as to define the place of an illumination display, and a casing inside of which a lens for guiding light of an inner light source to the appearance surface thereof is integrally formed with the casing using a light-permeable resin, in which a light transmitting area is integrally formed with the casing so as to be contiguous with the lenses, and on the inner surface of which a light-impermeable printed layer is provided. In this film molded casing, the light transmitting area is matched to the light transmitting area of the film molded member.

A card shaped casing includes a member having a construction such that a front panel or a back panel are unitarily formed. This member, for example, a back-panel combined frame, is constructed of a resin, etc. Accordingly, the number of expensive metal panels having adhesive layers and insulating layers, which are necessary for forming the casing, is reduced.
摘要:
The PC card of the present invention preferably includes a logic circuit operating in either a 16-bit mode or a 32-bit mode, a ground line on the circuit, a connector for transferring a signal between the circuit and the external device, and a series of elastic metal members arranged on the top surface of the connector and connected to the ground line. When the connector of the PC card is inserted into the PC card slot, the elastic metal member is retained by a support frame arranged on the periphery of the PC card slot, and is deformed upward toward the top surface of the connector. When the PC card is fully inserted into the slot, the elastic metal member urges the support frame and both are firmly connected.
