It may be provided in the link means 6 itself.

  Next, the operational effects of the switchgear according to the present invention and a small electronic device using the switchgear will be described.

First, in the closed state in which the second housing 3 is closed with respect to the first housing 2 shown in FIG. 1, as shown in FIGS. 6 and 10, the elastic means 17 of the sliding means 5. , 17 push the second housing 3 in the closing direction via the slide base member 13, so that the second housing 3 is locked to the first housing 2 in the closed state.

  Now, when the first housing 2 is held in one hand and the second housing 3 is pushed in the opening direction with the other hand to use the pocket computer 1, the elastic means 17, 17 of the sliding means 5 The second casing 3 slides and opens against the first casing 2 against elasticity, and the elastic means 17 and 17 are swung to compress and then swung in the extending direction. The second housing 3 is automatically slid and opened with respect to the first housing 2.

  On the other hand, the link means 6 has a lower end on the front end side of the second casing 3 at the first casing 2 even if the second casing 3 is tilted up with respect to the first casing 2. Therefore, the tilting operation by the link means 6 cannot be performed until just before the opening operation by the sliding means 5 is completed.

  In addition, the friction means 7 does not rotate in accordance with the tilt-up operation during the sliding operation of the second housing 3 with respect to the first housing 2, so that the second link pins 19, 19 Since the winding portions 13e and 13e of the slide base member 13 do not rotate around the sliding base member 13, the friction operation is not performed during the sliding operation by the sliding means 5.

  The sliding operation in the opening direction by the sliding means 5 causes the rear end side of the second casing 3 in the stopped state by the stopper means (not shown) as shown in FIG. When the tilt-up operation is performed, the joint arm 9 of the link means 6 rises together with the raising operation of the second housing 3 as shown in FIG. 11B, and the front end of the second housing 3 The tilt-up operation is performed while the part side slides slightly backward.

  At that time, the winding portions 13e and 13e of the slide base member 13 of the friction means 7 rotate around the second link pins 19 and 19 fixed to the connecting portions 9b and 9b of the joint arm 9 in a pressure contact state. Therefore, friction torque is generated, and the second casing 3 can be stopped at a tilt angle that can be easily seen by any user.

  Further, during this tilt-up operation, the guide members 21 and 21 of the guide means 24 are slid in the guide grooves 8d and 8d of the mounting members 8 and 8 so that the second housing The tilt angle of the body 3 with respect to the first housing 2 is regulated by the guide portions 21c and 21c reaching the end portions of the guide grooves 8d and 8d, and the maximum tilt angle is about 35 degrees in the embodiment. However, the tilt angle is not limited to this.

  In a state where the second housing 3 is tilted up with respect to the first housing 2, the joint arm 9 rises, and the first housing 2 and the rear end side of the second housing 3. In general, the flexible cable 11 appears to be exposed from the gap between the rear portion of the first housing 2 and the rear portion of the second housing 3, but the opening / closing device 4 according to the present invention. In particular, as shown in FIGS. 4 and 12, the flexible cable 11 can be made invisible by covering with a joint arm 9.

  The tilted-up second casing 3 returns to the original position by being tilted rearward, and is in a horizontal state. Therefore, the second casing 3 is pushed forward with respect to the first casing 2. At first, the elastic force of the elastic means 17, 17 is applied by the slide means 5, but it is slid and closed against the elastic force, and the action direction of the elastic means 17, 17 is changed from the intermediate closed position, The second casing 3 is automatically closed with respect to the first casing 2, and is locked in the closed state.

  Since the present invention is configured as described above, the second casing 3 can be opened and closed by sliding the second casing in the horizontal direction with respect to the first casing, and the second casing 3 can be opened immediately before the opening operation. Since it can be tilted up while being slightly slid with respect to the housing 2, the hand becomes wide and easy to operate, and the flexible cable is used when the second housing is tilted up with respect to the first housing. Can be suitably used as an opening / closing device for small electronic devices such as pocket computers, PDAs, electronic dictionaries, and cellular phones. Can provide a device having a new functional effect.
