  Here, with reference to FIG. 2 thru | or FIG. 4, the effect | action of the switchgear by the said Example is demonstrated in detail. 2 to 4, the second connecting member 40 moves to the right side in the drawing with respect to the first connecting member 20 in the direction in which the mobile phone is opened, and moves to the left side. Is the direction in which the mobile phone moves so as to close.

  First, referring to FIGS. 2A and 2B, the mobile phone 12 is completely closed. At this time, the second connecting member 40 moves to the left in the drawing with respect to the first connecting member 20 to the maximum. At this time, the 1B roller 44 and the 2B roller 46 of the second connecting member 40 are positioned on the left side with respect to the 1A roller 30 and the 2A roller 32 of the first connecting member 20. ing.

However, the mobile phone 12 is already in a completely closed state, and movement of the second connecting member 40 to the left side with respect to the first connecting member 20 is restricted, and the closed state is stably maintained. .

  In order to deploy the mobile phone 12 in the state of FIGS. 2A and 2B, an external force must be applied to push the second unit 16 in the direction of the arrow (the right side in the figure). Then, the second connecting member 40 of the opening / closing device 10 also moves to the right side with respect to the first connecting member 20 due to the external force, whereby the two rollers 44, 46 of the second connecting member 40 are moved. Will move to the right. By continuing to push the second unit 16 of the mobile phone 12 to the right with respect to the first unit 14, the two rollers 44, 46 of the second connecting member 40 are replaced with the two rollers 30 of the first connecting member 20, FIG. 3A and FIG. 3B show a state where the neutral position which is closest to 32 and reaches the nearest neutral position is shown.

The 2A roller 32 of the first connecting member 20 and the 2B roller 46 of the second connecting member 40 are also located on a line perpendicular to the movement axis 100. Therefore, due to the elastic force of the first elastic member 70 and the second elastic member 80, the second connecting member 40 does not automatically move to the left or right side with respect to the first connecting member 20.

  When the external force is removed before reaching the neutral state shown in FIGS. 3A and 3B, the second connecting member 40 is automatically moved to the left side by the elastic force of the first and second elastic members 70 and 80. So that the mobile phone 12 is automatically closed.

Is positioned on the right side of the two rollers 30 and 32 of the first connecting member 20. In this state, the first elastic member 70 and the second elastic member 80 apply an elastic force so that the second connecting member 40 moves to the right side with respect to the first connecting member 20. Therefore, the second connecting member 40 automatically moves to the right side with respect to the first connecting member 20, and stops in a state of moving to the right side to the maximum. This state is shown in FIGS. 4A and 4B.

  Referring to FIGS. 4A and 4B, the cellular phone 12 is completely open. At this time, the second connecting member 40 has moved to the right in the drawing relative to the first connecting member 20. At this time, the 1B roller 44 and the 2B roller 46 of the second connecting member 40 are positioned on the right side with respect to the 1A roller 30 and the 2A roller 32 of the first connecting member 20. ing. The two extensions 75 and 76 of the first elastic member 70 and the two extensions 85 and 86 of the second elastic member 80 are about to be separated from each other, and the first elastic member 70 and the second elasticity The member 80 gives an elastic force so that the second connecting member 40 moves to the right with respect to the first connecting member 20. However, the cellular phone 12 is already in a fully open state, and movement of the second connecting member 40 to the right side with respect to the first connecting member 20 is limited, and the open state is stably maintained. Since the process of closing the cellular phone from the open state is the reverse of the above-described opening process, detailed description thereof will be omitted.
