A connector housing (6) of the connector device (1) is composed of an outer housing (9) to be mounted onto a printed circuit board (2) by screwing, and an inner housing (8) connected to the outer housing (9) so as to be movable in the right and left direction with respect to the outer housing (9). Into the inner housing (8), there is incorporated a terminal (7) including a connecting portion (7a) to be connected by a terminal (5) of a mating connector device (3), a spring portion (7c), and a switch contact (7b) respectively formed integral with the terminal (7). On the printed circuit board (2), there is disposed an electrode (2a) with which the switch contact (7b) can be elastically contacted. Thanks to this structure, by switchingly moving the inner housing (8) in the right and left direction, circuit switching can be achieved.

A connector housing (1) of a connector (1) is constituted by a lower housing (7), which is mounted on a printed circuit board (2), and an upper housing (8) connected to the lower housing (7) in such a manner as to be able to perform shifting movement with respect the housing (7). Further, terminals (6) are provided in such a way as to penetrate through a partitioning wall portion (8a) of the upper housing (8) and through a connecting block portion (7b) of the lower housing (7). At that time, tapered holes (7d) are provided in the connecting block portion (7b). The terminals (6) are maintained in a state in which a bending deformation thereof caused by the shifting movement of the upper housing (8) is allowed. Consequently, when the connector (1) is connected to the mating connector (3), the connectors (1, 3) can be connected to each other by performing the shifting movement of the upper housing (8) thereby to concurrently absorb the positional displacement therebetween. Moreover, occurrences of problems, such as breakage and bend of the terminals (6) at that time, are prevented.

A lever (14) is pivotally movably supported on a female connector (11). In accordance with the movement of a slide member (13) relative to the female connector (11), the lever (14) is pivotally moved while held in engagement with a tongue portion (29b) of an engagement portion (29) formed on a male connector (16), and with this construction the inserting force is reduced. When the slide member (13) is completely drawn out relative to the female connector (11), an engagement projection (14g) of the lever (14) is engaged with an engagement claw (26a) of an elastic arm portion (26), and the lever (14) is held in this position. When a projection (29a) of the engagement portion (29) elastically deforms the elastic arm portion (26), the retained condition of the lever (14) is canceled, so that the lever (14) is allowed to be pivotally moved.

A fastening device for facilitating temporary fastening of an electronic component to a circuit board. The fastening device includes a base embedded in an electronic device and two elastic plates extending from the base. Each elastic plate includes a diagonal portion, which extend diagonally relative to the plane of the circuit board, and a leg, which extends continuously from the diagonal portion. When the legs are inserted through a connecting hole of the circuit board, the resilient force of the elastic plates presses the diagonal portions against the wall of the connecting hole.

A connector has terminals, each having a tip end portion. A wiring board has through holes. A land is provided on the wiring board about each through hole. When the connector is mounted on the wiring board, each terminal is connected to one of the lands with a part of the tip end portion being located in the corresponding through hole. The ratio of the cross-sectional area of each tip end portion to the cross-sectional area of each through hole is at least 0.11 and no more than 0.89. This improves the reliability of the joint portions between the terminals and the wiring board.

To provide a mobile terminal device that can eliminate influence of static electricity upon signal lines of a signal-line flexible board that is placed through a connecting unit that connects two casings to be able to overlie one another. In the mobile terminal device, one of the casings and the other casing are connected through a connecting unit to be able to overlie one another, and a signal-line flexible board that connects circuit boards housed in one of the casings and the other casing, respectively, is placed through the connecting unit. The mobile terminal device includes a pair of frame-grounded flexible boards that are formed wider than the signal-line flexible board to have a conductor pattern frame grounded, and sandwich both outer surfaces of the signal-line flexible board therebetween.

A photoelectric encoder includes: a scale having a grating formed with a predetermined period Ps; and a detector head being movable relative to the scale and including a light source and a light receiving unit. In a configuration where light receiving elements in the light receiving unit output N-points light and dark signals (N is an integer of 3 or more), and where phases of the N-points light and dark signals are detected by a least-squares method to fit a sinusoidal function with fixed period to N-points digital signals digitized from the N-points light and dark signals, an N-points light and dark signal period P is set at an integral multiple of a data-point interval w of the N-points digital signals, and an overall length M of the light receiving elements is set at an integral multiple of the N-points light and dark signal period P. Thereby, position detecting errors occurring due to a stain of the scale and/or a defect in the grating can be reduced by simple computing.
