  • Patent number: 6247958
    Abstract: A female connector for an IC card having a housing provided with terminal pin receiving holes provided with positioning projections. Terminal pins each having a base part and contact parts, and inserted in the terminal pin receiving holes are positioned by the positioning projections. A front end portion of the base part of each terminal pin near the contact pin receiving hole is held in a space, the free front end portion of the base part is held in a space between the positioning projections and a side wall of the terminal pin receiving hole to prevent the base part from buckling.

  • Patent number: 6213811
    Abstract: In an IC card with socket, a conductive member is attached to the front surface section of a socket housing into which the pin contacts of an IC card connector device (not shown) are inserted and electrically connected to a metal cover. With this arrangement, even if static electricity having a large amount of charge is charged to an operator, the static electricity is discharged to the conductive member and removed without discharging to socket contacts. Accordingly, the LSI in the IC card is not broken by the static electricity.

  • Patent number: 6122114
    Abstract: An optical-element supporting device arranged to support and set one or a plurality of optical elements in respective predetermined positions in an optical axis direction, includes ring frames mounted respectively on the plurality of optical elements and each having a plurality of projections protruding in the optical axis direction, and a pinching structure for pinching the ring frames being piled up in the optical axis direction (the pinching structure comprising, for example, a lens barrel member which accommodates the ring frames mounted on the optical elements and leaf springs mounted near an end part of the lens barrel member in the optical axis direction), wherein the projections of the ring frames and respective pinching positions of the pinching structure are axially aligned in parallel with the optical axis direction.

  • Patent number: 5880405
    Abstract: A terminal structure for a surface mount electronic part including a terminal holding member formed from a synthetic resin, and external terminal extending from the terminal holding member for soldering to soldering lands of a printed wiring board. Each of the external terminals is held on the terminal holding member such that a straight portion projects laterally from the terminal holding member and is restricted direction (i.e., in width and thickness directions). The outermost tip portion of each external terminal includes an offset portion which is stepped downwards relative to the straight portion of the external terminal includes an offset portion which is stepped downwards relative to the straight portion of the external terminal and which is formed by half punching. The offset portion is provided for soldering to a soldering land of the printed wiring board.

  • Patent number: 5683258
    Abstract: A PC card connector has an injection mechanism which is improved so as to make it possible to push a PC card in a substantially straightforward direction, in which the PC card is withdrawn, without converting rotary motion into linear motion. The PC card connector is further improved so as to be able to assure the constant smooth withdrawal of the PC card without the need of a complicated or large-sized structure. The PC card connector is provided with a push rod which is pressed to remove the PC card, an eject lever which is supported by a first fulcrum in a pivotal manner, and which has one end engaged with the push rod and has a first claw at the other end to eject the PC card, and a rotary arm which is supported by a second fulcrum in a pivotal manner and has at one end a second claw to eject the PC card, and which has the other end connected to a predetermined location in the eject lever.
