They are provided symmetrically on the left and right sides of the panel 2. The first sliders 4 on both sides have an integral structure.

Next, the operation of the opening / closing device 1 will be described.
As shown in FIG. 1, in a state where the first slider 4 extends forward from the chassis 3, the pin 21 of the display panel 2 is positioned at the lower end of the guide 71, and the display panel 2 falls back to display. The display surface 22 of the panel 2 faces upward. Further, the claw 52 of the second slider 5 is located at a position farther forward than the stopper 84 of the roller guide 8, and the sliding roller 61 of the swing rod 6 is the first inclined surface 81 and the second inclined surface of the roller guide 8. It is located away from the surface 82 and the horizontal holding surface 83 and in front of the roller guide 8. Further, the lower surface of the front end portion of the swing rod 6 is in contact with the front end portion of the first slider 4 at point A, thereby preventing the swing rod 6 from rotating counterclockwise. The lock pin 62 comes into contact with the upper edge of the lock protrusion 53, and this prevents the rocking rod 6 from rotating clockwise. As described above, since the swing rod 6 does not rotate in either direction, the display panel 2 does not vibrate with respect to the chassis 3 and the guide plate 7.

  When the first slider 4 slides backward by the drive mechanism, the swinging rod 6 also moves rearward together with the first slider 4, and the pin 21 of the display panel 2 moves along the vertical guide portion 72 of the guide 71. As a result, the display panel 2 stands up, and the display surface 22 of the display panel 2 faces forward. At this time, the second slider 5 is also moved rearward together with the first slider 4 by being pulled rearward by the tension spring 91, and the lock pin 62 of the swing rod 6 is in contact with the upper edge of the lock protrusion 53. And the state where the front end portion of the swing rod 6 is in contact with the front end of the first slider 4 is maintained.

  As shown in FIG. 2, when the pin 21 is positioned at the upper end portion of the vertical guide portion 72, the sliding roller 61 comes into contact with the front end portion of the first inclined surface 81, and the claw 52 of the second slider 5 becomes the roller. It abuts against the stopper 84 of the guide 8 and is locked. Therefore, when the first slider 4 slides further backward by the driving mechanism, the rearward movement of the second slider 5 is suppressed, the lock pin 62 is separated from the upper edge of the lock protrusion 53, and the swing rod 6 is moved. It can be rotated clockwise.

  When the first slider 4 is moved further rearward by the drive mechanism, the sliding roller 61 slides on the first inclined surface 81, and the swing rod 6 rotates clockwise against the torsion spring 92, and the display panel While the lower end of 2 moves rearward and upward, the display panel 2 stands up so that the display surface 22 of the display panel 2 faces forward. As shown in FIG. 3, when the sliding roller 61 is positioned closer to the second inclined surface 82 of the first inclined surface 81, the display surface 22 of the display panel 2 faces forward.

  When the first slider 4 moves further rearward by the driving mechanism, the sliding roller 61 slides on the second inclined surface 82, and the swing rod 6 rotates clockwise against the torsion spring 92. Thereby, the lower end part of the display panel 2 moves rearward and upward, the pin 21 moves forward along the lateral guide part 73, and the display panel 2 falls forward.

  Then, when the first slider 4 is moved further rearward by the driving mechanism, the sliding roller 61 is positioned on the horizontal holding surface 83 and the pin 21 is positioned on the front end portion of the lateral guide portion 73 as shown in FIG. The display surface 22 of the display panel 2 faces forward and obliquely downward. In a state where the sliding roller 61 is positioned on the horizontal holding surface 83, a line segment connecting the sliding roller 61 and the connecting shaft 63 is parallel to the horizontal holding surface 83.

  When the first slider 4 is moved forward by the drive mechanism from the state of FIG. 4, the sliding roller 61 moves from the horizontal holding surface 83 to the second inclined surface 82, and the sliding roller 61 is inclined second by the torsion spring 92. The second inclined surface 82 slides while being pressed against the surface 82. As a result, the swing rod 6 rotates counterclockwise, the lower end portion of the display panel 2 moves forward and downward, the pin 21 moves rearward along the lateral guide portion 73, and the display panel 2 stands up. . At this time, since the second slider 5 is pulled backward by the tension spring 91, even if the first slider 4 moves forward, the second slider 5 does not move forward.

  When the first slider 4 is moved forward by the drive mechanism from the state shown in FIG. 3, the sliding roller 61 slides on the first inclined surface 81 while being pressed against the first inclined surface 81 by the torsion spring 92. The swing panel 6 rotates counterclockwise, and the display panel 2 tilts backward so that the display surface 22 of the display panel 2 faces upward.

  When the first slider 4 is further moved forward by the drive mechanism, the lock pin 62 comes into contact with the upper edge of the lock projection 53 and the front end of the swing rod 6 is located on the first slider 4 as shown in FIG. Abuts the front end. In addition, since the tension spring 91 has a natural length in the state of FIG. 2, when the first slider 4 is moved forward by the drive mechanism from the state of FIG. 2, the second slider 5 is integrated with the first slider 4. Move forward. At this time, the lower end portion of the display panel 2 moves forward, the pin 21 moves downward along the vertical guide portion 72, and the display panel 2 moves backward. When the first slider 4 moves to the previous limit position, the pin 21 of the display panel 2 is positioned at the lower end of the guide 71, and the display surface 22 of the display panel 2 faces upward (see FIG. 1).

  As described above, according to this embodiment, the claw 52 of the second slider 5 contacts the stopper 84 as shown in FIG. 2 from the state where the first slider 4 extends most forward as shown in FIG. Up to the contact state, the rotation of the rocking rod 6 is inhibited by the lock protrusion 53 of the second slider 5 and the first slider 4, so that the upper and lower ends of the lower end of the display panel 2 with the connecting shaft 63 as the center. Vibration does not occur. Therefore, the rattle noise of the display panel 2 can be prevented, and the visibility of the display panel 2 is improved. If the biasing force of the torsion spring 92 is increased, the rotation of the rocking rod 6 can be suppressed even if the lock projection 53 of the second slider 5 does not contact the lock pin 62, and the rattle noise of the display panel 2 can be reduced. Can be prevented. However, when the swing rod 6 is rotated by the first inclined surface 81 or the second inclined surface 82, a very large load is required because the urging force of the torsion spring 92 is large. In the present embodiment, it is not necessary to increase the urging force of the torsion spring 92, so a large load is not required.

  3 and 4, when the sliding roller 61 is in contact with the first inclined surface 81, the second inclined surface 82, or the horizontal holding surface, the lock pin 62 is the locking protrusion of the second slider 4. Since it is away from 53, the swing rod 6 can rotate around the connecting shaft 63. Therefore, when the first slider 4 moves back and forth in a state where the sliding roller 61 is in contact with the first inclined surface 81 or the second inclined surface 82, the swing rod 6 rotates.

  The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.

  In the above embodiment, the display panel 2 has been described as an example of the front panel. However, a lid panel that covers the front surface of the electronic device body may be used as the front panel.

  Further, instead of the torsion spring 92, a plate spring may be used to urge the swing rod 6 counterclockwise. A compression spring may be used instead of the tension spring 91, but in the case of a compression spring, the spring hook 41 of the first slider 4 is in front of the spring hook 51 of the second slider 5.

  In addition, the stopper 84 is formed on the roller guide 8, but may be formed on the side plate 32 of the chassis 3 as long as it can be locked with the claw 52. Further, although the guide 71 is formed on the guide plate 7 fixed to the chassis 3, it may be formed directly on the chassis 3.
