Abstract: The present invention has improved opening operationality of a cover, which enables a reduction in thickness of a rotational supporting mechanism performing an opening and closing operations of the cover in a planar direction, and enables a user to open the cover with a single touch of one hand. Therefore, in the present invention, when a pressing means, which presses against a cam surface of an eccentric cam that rotates in a planar direction, is fitted to one portion on the cam surface corresponding to a 180-degree rotated position corresponding to the open position or the other portion corresponding to the closed position, a rotational position of the eccentric cam is controlled to stop the rotation of the cover.

Abstract: A memory card connector is offered which has a locking function and which permits both a memory card having a locking recess in its side surface and a memory card having no locking recess in its side surface to be inserted and withdrawn. The connector comprises a connector body having a tapering guide groove, a slider provided with a slide groove perpendicular to the direction of sliding motion, a locking pawl engaged in the tapering guide groove of the connector body via a guide pin, and a first coil spring mounted to the slider. This slider is slidably mounted to the connector body via a second coil spring to form an alternate mechanism. The locking pawl is slidably fitted in the slide groove of the slider and can engage the locking recess formed in one side surface of the memory card. The first coil spring biases the locking pawl inward at all times.

Abstract: The present invention provides a space-saving rotary structure for relaying signals which can relay a large number of signal lines without causing a disconnection of the signal lines. The rotary structure for relaying signals comprising a fixed frame which is supported and fixed in the inside of first and second casings, a rotary sleeve which is rotatably inserted into a through hole of the fixed frame and has a distal end thereof projected to the outside of the first and the second casing, a rotary frame which is arranged outside the first and second casings and is fixed to the distal end of the rotary sleeve such that the rotary frame is integrally rotatable with the rotary sleeve, and a flexible printed wiring film which has a distal end thereof pulled out to the outside of the first and second casings along the rotary sleeve and is wound around a winding tongue of the rotary sleeve which is positioned in the inside of the first and the second casings.
