Further, the friction means is not limited to the embodiment, and the connection means 6 may be used for the design.

Next, the operation and effect of the opening device of the present invention and the small electronic device to which the opening device is applied will be described.

First, with respect to the second casing 3 of the first casing 2 shown in Fig. 1, in a closed state, as shown in Figs. 6 and 10, the elastic means 17, 17 of the sliding means 5 are used by the carriage The element 13 presses the second casing 3 in the closing direction, and the second casing 3 is locked with respect to the first casing 2 in the closed state.

Next, in order to use the pocket type computer 1, the first casing 2 is held in one hand, and the second casing 3 is pressed in the opening direction in the other hand, in order to resist the sliding means 5 The elastic force of the elastic means 17, 17 causes the second housing 3 to slide open relative to the first housing 2. After being rotated and compressed by the elastic means, the second housing 3 is automatically slid open relative to the first housing 2 after being rotated in the extending direction.

On the other hand, even if the second casing 3 is tilted with respect to the first casing 2, since the lower end portion of the front end side of the second casing 3 comes into contact with the upper surface of the first casing 2, it is not possible to pass the sliding means. 5 When the opening operation is completed, the tilting operation cannot be performed by the connecting means 6.

Further, when the second casing 3 slides relative to the first casing 2, since the carriage member 13 cannot rotate with the upward tilting operation, the rotation of the second coupling rods 19, 19 is not the slider member 13 shaft. Since the rotation of the portions 13e and 13e is performed, the friction means 7 does not generate a frictional motion when the sliding operation is performed by the sliding means 5.

As shown in FIG. 11(a), the sliding operation of the sliding means 5 in the opening direction is performed by the stopper means (not shown), and the upright side of the rear end side of the second casing 3 is tilted up. action. As shown in Fig. 11(b), the joint arm 9 of the connecting means 6 rises together with the rising operation of the second casing 3, and the front end portion side of the second casing 3 continues to slightly slide to generate the upper side. Tilting action.

At this time, the second connecting rods 19 and 19 fixed to the connecting portions 9b and 9b of the joint arm 9 are rotated by the axial portions 13e and 13e of the slide member 13 of the friction means 7, and friction is generated. Torque, whereby the second housing 3 can be stopped at any angle that is easy for the user to view.

Moreover, in the upward tilting operation, the guiding portions 21c, 21c of the guiding elements 21, 21 of the guiding means 24 are in the guiding groove of the assembling elements 8, 8. Sliding in 8d and 8d, the inclination angle of the second casing 3 with respect to the first casing 2 can be restricted by the guide portions 21c, 21c reaching the end portions of the guide grooves 8d, 8d. The maximum tilt angle of this embodiment is about 35 degrees, which is not limiting.

Then, when the second housing 3 is tilted relative to the first housing 2, the joint arm 9 is raised to block the rear end side of the first housing 2 and the second housing 3, usually by the first The gap between the casing 2 and the second casing 3 is exposed and visible, and the opening device 4 of the present invention, as shown in particular in FIGS. 4 and 12, is shielded by the joint arm 9. The flexible wire 11 can be prevented from being seen.

The second housing 3 that has been tilted up is returned to the original position by falling backward, and becomes a horizontal state. Further, the second casing 3 is pressed toward the front side of the first casing 2, and the elastic force of the elastic means 17, 17 is started via the sliding means 5, and the second casing 3 is slidably closed to resist the elastic force. The intermediate closed position starts to change the direction of action of the elastic means 17, 17, and the second housing 3 is automatically closed relative to the first housing 2 and locked in the closed state.

According to the present invention, in addition to the second housing being slidable in the horizontal direction with respect to the first housing, the second housing can continue to generate a slight sliding rearward relative to the first housing during the opening operation. The upward tilting action increases the grip range and is easier to operate. Moreover, when the second housing is tilted relative to the first housing, since the flexible lead wire or the like is not exposed to the outside, it is not aesthetically pleasing, and thus can be applied to small electronic devices such as a pocket type computer, a PDA, an electronic dictionary, and a mobile phone. Open the device. In addition, it can also be applied to other small electronic devices having new functional effects.
