  • Patent number: 6702506
    Abstract: In a belt clip for portable electronic equipment by use of rewind urging force of a torsion coil spring, a detachment preventing mechanism of a guide shaft, serving as a shaft center of a rotational mechanism, is implemented with a simple structure so as to improve a reduction in the number of parts and yield. The respective shaft support portions 11a and 12a of a hang stopper plate 1 and both side plates 13a and 14a of a bracket 4 are combined with each other, a torsion coil spring 3 is twisted from a natural state and interposed therebetween in such a manner that a guide rod 21 is passed through a space formed therebetween, but movement of the torsion coil spring 3 to an axial direction and a change in a coil length are restrained by a groove 15 of the hang stopper plate 1 and the side plate 13a of the bracket 4.

  • Patent number: 6395980
    Abstract: In a battery case mounted on electronic equipment, the thickness of the battery case is reduced as obtaining the holding force of batteries with respect to vibration and impact by use of a case main body with a simple structure and a case cover. A depth of a battery containing portion of the case main body 1 is structured such that a side face of each battery is protruded outwardly than an end face of a frame portion in a state that the batteries 2 are contained. On the other hand, the case cover 10 is formed of plate material covering the side face of each of the respective contained batteries 2, and plate-like magnets 14 and 15 are adhered onto faces opposite to the respective batteries 2. The case cover 10 is attached to the respective dry batteries by an absorbing force of the plate-like magnets 14 and 15 to share a holding force between the dry batteries, thereby preventing the dry batteries from being detached even if vibration and impact act.

  • Patent number: 6364271
    Abstract: An electronic apparatus installation structure has an adapter with rotatably supporting a rotating shaft, and having a bearing part having elongated holes that cause exposure of screw holes and a pin hole of a rotating shaft and a base part. A pin of the rotating shaft is pressed into the pin hole, thereby restraining thrust-direction movement, and also limiting the swinging range of the rotating shaft. Through holes are provided on a radio apparatus at locations corresponding to the screw holes on the rotating shaft, and mounting screws are used to fix the radio apparatus to the bearing part of the adapter.
