Abstract: The electronic apparatus includes: a housing having an opening for inserting a card and a cover member, the opening being closed when a medium is not inserted, the cover member being pressed by the medium when the medium is inserted so that the cover member is rotated to go down at least partially; a medium slot disposed at a position facing the opening and receives a medium inserted through the opening; and an insulation sheet spread under the medium slot and extended to a position in which the cover member rotated to go down by being pressed by the inserted medium covers the insulation sheet.

Abstract: The present invention relates to a structure for fixing an element to a printed wiring board. The fixing structure includes a spacer, the printed wiring board, and a sealant. The spacer has a first end to which the element is to be fixed and a second end to be fixed to the printed wiring board. The printed wiring board has a hole having a shape determined in relation to the shape of the second end of the spacer. The sealant is filled in the hole of the printed wiring board to fix the second end of the spacer to the printed wiring board. The second end of the spacer has a projection having a length smaller than the thickness of the printed wiring board and located in the hole of the printed wiring board.

Abstract: An information processing apparatus which includes a first member (for example, a cover having a display unit thereon), a second member (for example, an apparatus body having a keyboard thereon), and a connection unit. The first member has a first face (for example, a face on which the display unit is provided) and a second face (for example, an outer face of the cover). The connection unit connects the first and second members to each other such that the first and second members are displaceable relative to each other between a first condition wherein the first face opposes the second member and a second condition wherein the second face opposes the second member. The first member has a hook member provided thereon such that the hook member can selectively project from one of the first and second faces. The second member has a hole for being engaged by the hook member.

Abstract: An information processing device suitable for portable use. The information processing device includes a first member (e.g., a cover having a display unit), a second member (e.g., a body having a keyboard unit), a connecting member for connecting the first and second members so that these members can be relatively displaced, and a switch mechanism provided in the second member. The second member has an engaging portion (e.g., a hole), and the first member includes a hook member to be engaged with the engaging portion. The switch mechanism functions to switch on and off a signal in synchronism with movement of the hook member. According to the structure having such switch mechanism, it can be possible to provide a device which can prevent an improper switching operation.
