As a result, the gear 261 and the gear 262 rotate in opposite directions in synchronism, so that the first hinge portion 41 and the second hinge portion 42 have the same angle in the opposite direction around the second rotation axis S2. Only rotate.

Next, the opening / closing operation | movement of the 1st housing | casing 20 and the 2nd housing | casing 30 is demonstrated.
First, as shown in FIGS. 4A and 1A, a closed state in which the first surface 23 of the first housing 20 and the second surface 33 of the second housing 30 are opposed to each other and stacked. explain. For convenience of explanation, FIGS. 1B and 1C illustrate the second hinge portion 42.
In this case, in the hinge portion 40, the second shaft portion 434 (second rotation shaft S2) of the first block 43 and the second shaft portion 444 (third rotation shaft S3) of the second block 44 are stacked one above the other. And directed in the same direction (see FIG. 1C). The first rotation axis S1 is on the same straight line in the first hinge part 41 and the second hinge part 42.

When opening the first housing 20 and the second housing 30, in FIG. 4A, the first housing 20 and the second housing 30 are moved in the direction of arrow A about the first rotation axis S1, and as shown in FIG. The housing 20 is opened.
FIGS. 4B and 6 show an open state in which the first housing 20 and the second housing 30 are completely opened. At this time, the first rotation axis S1 for relatively rotating the first housing 20 and the second housing 30 is the first ridgeline 211 of the first housing 20 and the second ridgeline 311 of the second housing 30. Are located in parallel in the vicinity of. That is, the first rotation axis S <b> 1 has an axis in the direction along the connection surface between the first housing 20 and the second housing 30.
Therefore, the first display unit 24 on the first surface 23 of the first housing 20 and the second display unit 34 on the second surface 33 of the second housing 30 are on the same plane. Moreover, since the 1st ridgeline 211 of the 1st housing | casing 20 and the 2nd ridgeline 311 of the 2nd housing | casing 30 are adjacent, the 1st display part 24 and the 2nd display part 34 are substantially continuous. .

Similarly, the 3rd ridgeline 221 of the 3rd surface 25 of the 1st housing | casing 20 and the 4th ridgeline 321 of the 4th surface 35 of the 2nd housing | casing 30 are mutually parallel, and adjoin (refer FIG. 2). ).
Here, the 3rd ridgeline 221 and the 4th ridgeline 321 should just be arrange | positioned very close mutually, and may mutually contact. The proximity in the present invention does not matter whether the third ridge line 221 and the fourth ridge line 321 are in contact with each other.

In this state, a part of the first hinge portion 41 and the second hinge portion 42 protrudes upward from the first surface 23 and the second surface 33 (see FIG. 4B).
Further, the second rotation axis S2 and the third rotation axis S3 of the hinge portion 40 extend in a straight line. In this state, the first housing 20 and the second housing 30 are not locked and can be easily closed.

That is, the first hinge portion 41 is rotated in the direction of arrow A in FIG. 6, and the second hinge portion 42 is rotated in the direction of arrow B. The rotation axes at this time are the second rotation axis S2 and the third rotation axis S3.
As a result, as shown in FIG. 7, the first rotation axis S1 has an angle (for example, 90 degrees) with respect to when the first casing 20 and the second casing 30 are opened and closed. The first casing 20 and the second casing 30 are locked in the open state because they cannot rotate about the rotation axis S1.

In addition, when rotating the 1st hinge part 41 and the 2nd hinge part 42, what is necessary is just to rotate any one. That is, when any one of them is rotated, the first hinge portion 41 is operated by the action of the timing belt 27 (see FIG. 2) connecting the gear 261 of the first hinge portion 41 and the gear 262 of the second hinge portion 42. And the 2nd hinge part 42 synchronizes and rotates only the same angle to the opposite direction.

That is, the first hinge portion 41 is rotated in the direction of arrow A in FIG. 7, and the second hinge portion 42 is rotated in the direction of arrow B. The rotation axes at this time are the second rotation axis S2 and the third rotation axis S3.

As a result, as shown in FIGS. 4D and 8, the first rotation shaft S1 of the first hinge part 41 and the second hinge part 42 is positioned on the same straight line, and the first casing 20 and the first hinge 20 The two housings 30 can be relatively rotated. At this time, the first rotation axis S1 moves from the first surface 23 side of the first housing 20 and the second surface 33 side of the second housing 30 to the third surface 25 side and the fourth surface 35 side. Therefore, the first housing 20 and the second housing 30 cannot be rotated in the closing direction, and are rotated only in the folding side (the arrow D direction in FIG. 4D and the arrow A direction in FIG. 8). .
FIG. 9 shows a state in the middle of turning back.

  FIGS. 4E and 10 show a state where the first housing 20 and the second housing 30 are completely folded back. In this state, the first display unit 24 of the first housing 20 and the second display unit 34 of the second housing 30 are stacked on the outside.

For this reason, since the first surface 23 of the first housing 20 and the second surface 33 of the second housing 30 are arranged close to each other on the same plane, the display units 24 of both the housings 20 and 30 are arranged. , 34 can be displayed as a single screen.

  The first rotation axis S1 is attached to the first casing 20 so as to be rotatable around the second rotation axis S2, and is attached to the second casing 30 so as to be rotatable around the third rotation axis S3. It has been. For this reason, in the open state, the direction of the first rotation axis S1 can be changed by rotating the first rotation axis S1 around the second rotation axis S2 and the third rotation axis S3. Thereby, the relative rotation of the 1st housing | casing 20 and the 2nd housing | casing 30 can be prevented, and an open state can be maintained.

  Further, according to the electronic device 10 of the present invention, in the open state, the third ridge line 221 of the first housing 20 and the fourth ridge line 321 of the second housing 20 are in contact with or close to each other. In this state, the third surface of the first housing 20 is rotated by rotating the first rotation shaft 180 degrees (180 degrees from the closed state) about the second rotation shaft S2 and the third rotation shaft S3. The first housing 20 and the second housing 30 can be relatively rotated until the folded state where the 25 and the fourth surface 35 of the second housing 30 face each other.
