The best mode for carrying out the present invention will be described below with reference to FIGS.
1 and 2 show a mobile phone (mobile device) 1 according to the present invention. The mobile phone 1 includes a transmission case (first case) 2, a reception case (second case) 3, and a biaxial hinge device 4. The transmission case 2 is connected to the hinge body 41 of the biaxial hinge device 4 so as to be rotatable about the first rotation axis L1. The receiving case 3 is connected to the hinge body 41 so as to be rotatable about a second rotation axis L2 parallel to the first rotation axis L1. The transmitting case 2 and the receiving case 3 and the hinge body 41 can be rotated relative to each other. However, in the following, for convenience of explanation, the transmitting case 2 is positioned horizontally with its thickness direction directed in the vertical direction. The hinge body 41 is fixed and rotates about a first rotation axis L1 that is horizontal with respect to the transmission case 3, and the reception case 3 is centered about a second rotation axis L2 that is horizontal with respect to the hinge body 41. It shall rotate as follows.

  As shown in FIG. 3, the hinge main body 41 has a first start position where one side surface 41 a of the hinge main body 41 abuts against one end surface 2 a of the transmission case 2, as shown in FIG. As shown, the other side surface 41b of the hinge main body 41 can rotate in a range of about 180 ° between the first end position where the other side surface 41b of the transmission case 2 abuts against the first end surface 2a. As shown in FIG. 3, the receiving case 3 has a second starting end position where one end surface 3a of the receiving case 3 abuts against one side surface 41a of the hinge main body 41, as shown in FIG. In addition, the range of about 180 ° between the one end face 3a of the receiving case 3 and the second end position shown in which the other end face 41b of the hinge body 41 abuts can be rotated.

  When the hinge body 41 is located at the first starting end position and the receiving case 3 is located at the second starting end position, the receiving case 3 is substantially parallel to the transmitting case 2 as shown in FIG. The front surface 2b of the transmission case 2 and the front surface 3b of the reception case 3 face each other with a slight gap. Hereinafter, the position of the reception case 3 at this time is referred to as a folding position. The folding position of the reception case 3 may be regulated by abutting the front surface 3 b of the reception case 3 against the front surface 2 b of the transmission case 2. In such a case, either between the one end surface 2a of the transmitting case 2 and the one side surface 41a of the hinge main body 41 or between the one end surface 3a of the receiving case 3 and the one side surface 41a of the hinge main body 41. A slight gap is formed on either side.

  When the hinge body 41 is located at the first terminal position and the receiving case 3 is located at the second terminal position, the receiving case 3 is substantially parallel to the transmitting case 2 as shown in FIG. The back surface 2c of the transmission case 2 and the back surface 3c of the reception case 3 face each other with a slight gap. Hereinafter, the position of the reception case 3 at this time is referred to as a reverse folding position. The reverse folding position of the reception case 3 may be regulated by abutting the back surface 3 c of the reception case 3 against the back surface 2 c of the transmission case 2. In such a case, either between the one end surface 2a of the transmitting case 2 and the other side surface 41b of the hinge body 41 or between the one end surface 3a of the receiving case 3 and the other side surface 41b of the hinge main body 41. A slight gap is formed on either side. When the reception case 3 is located at the folding position or the reverse folding position, the first and second rotation axes L1 and L2 are located at the same position in the horizontal direction and are lined up and down. The first and second rotation axes L1 and L2 may be arranged so as to be slightly separated from each other in the horizontal direction when the receiving case 3 is located at the folding position or the reverse folding position.

  In this cellular phone 1, the situation where the hinge body 41 is located at the first start position and the receiving case 3 is located at the second end position, and the hinge body 41 is located at the first end position, and the receiving case. The situation where 3 is located at the second starting position does not occur as long as the receiving case 3 is normally rotated, but the receiving case 3 is fixed to the hinge main body 41 with the hinge main body 41 fixed in position. By forcibly turning 41, the above two situations can be generated. When the hinge body 41 is located at the first start position and the reception case 3 is located at the second end position, the reception case 3 is located at the folding position as indicated by an imaginary line in FIG. It becomes symmetrical with respect to the receiving case 3 and the second rotation axis L2. When the hinge body 41 is located at the first terminal position and the receiving case 3 is located at the second starting position, the receiving case 3 is located at the reverse folding position, as indicated by an imaginary line in FIG. The receiving case 3 is symmetrical with respect to the second rotation axis L2.

  When the transmitting case 2 is fixed in position and the receiving case 3 is normally rotated with respect to the transmitting case 2 by applying the rotational force only to the receiving case 3, the hinge body 41 and the receiving case 3 are By the action of the hinge device 4, the hinge device 4 is rotated at a predetermined angle in a predetermined order. That is, it is assumed that the receiving case 3 is now located at the folding position shown in FIG. In this state, if it is attempted to rotate the reception case 3 toward the reverse folding position shown in FIG. 7 (hereinafter, the rotation direction of the reception case 3 is referred to as an open direction, and the reverse direction is referred to as a close direction). First, the hinge body 41 is rotated 90 ° with respect to the transmission case 2 about the first rotation axis L1. Hereinafter, the position of the hinge body 41 at this time is referred to as a first intermediate position. The hinge body 41 is stopped with a predetermined magnitude of force at the first intermediate position. When the hinge main body 41 rotates from the first starting end position to the first intermediate position, the receiving case 3 rotates integrally with the hinge main body 41. Therefore, when the hinge main body 41 is rotated to the first intermediate position, the receiving case 3 is erected in the vertical direction from the hinge main body 41 as shown in FIG.

  When the receiving case 3 is further rotated in the opening direction from the standing state, the hinge main body 41 maintains a stopped state at the first intermediate position, and the receiving case 3 rotates about the second rotation axis L2 with respect to the hinge main body 41. Move. When the receiving case 3 is rotated 90 ° from the second start position with respect to the hinge main body 41, the receiving case 3 is stopped by a predetermined force. Hereinafter, the rotation position of the reception case 3 with respect to the hinge body 41 at this time is referred to as a second intermediate position. The reception case 3 rotated to the second intermediate position itself is rotated 90 ° relative to the hinge body 41 and the hinge body 41 is rotated 90 ° relative to the transmission case 2. The transmission case 2 is turned by 180 ° and becomes horizontal. As a result, as shown in FIG. 5, the transmission case 2, the apparatus main body 41, and the reception case 3 are arranged horizontally on a straight line.

  When the receiving case 3 is further rotated in the opening direction from the second intermediate position, the hinge main body 41 is maintained in a stopped state, and the receiving case 3 is rotated. The receiving case 3 reaches the second end position when it is rotated approximately 90 ° from the second intermediate position. Then, as shown in FIG. 6, the one end surface 3 a of the receiving case 3 stops when it abuts against the other side surface 41 b of the hinge body 41, and is maintained at a second terminal position with a predetermined amount of force.

  Thereafter, when the receiving case 3 is further rotated in the opening direction, the receiving case 3 maintains a stopped state with respect to the hinge body 41, and the hinge body 41 rotates from the first intermediate position toward the first terminal position. Move. When the hinge body 41 is rotated to the first terminal position, the other side surface 41b abuts against the one end surface 2a of the transmission case 2 and stops, and is maintained at the first terminal position with a predetermined amount of force. While the hinge main body 41 is rotated to the first terminal position and the receiving case 3 is rotated to the second terminal position, the receiving case 3 is positioned at the reverse folding position.

  When the reception case 3 is rotated in the closing direction from the reverse folding position, the reception case 3 is first rotated from the second terminal position to the second intermediate position as shown in FIG. Next, the hinge body 41 rotates from the first terminal position to the first intermediate position. As a result, the entire mobile phone 1 is in the state shown in FIG. Thereafter, until the reception case 3 reaches the folding position, the reception case 3 and the hinge main body 41 are alternately rotated by 90 ° in the reverse order to the case where the reception case 3 is rotated in the opening direction.

  Next, the biaxial hinge device 4 capable of rotating the receiving case 3 and the hinge body 41 in the above order will be described. As shown in FIG. 9, the biaxial hinge device 4 includes a pair of first hinges 5A. , 5B and a pair of second hinges 6A, 6B. The pair of first hinges 5A and 5B are respectively disposed at one end and the other end of the hinge body 41 in a state where the respective axes coincide with the first rotation axis L1. The pair of second hinges 6A and 6B are respectively disposed at one end and the other end of the hinge body 41 in a state in which the respective axes coincide with the second rotation axis L2. The first hinges 5A and 5B connect the transmission case 2 and the hinge body 41 so as to be rotatable about the first rotation axis L1. The second hinges 6A and 6B connect the receiving case 3 and the hinge body 41 so as to be rotatable about the second rotation axis L2. In addition, about any one of 1st hinge 5A, 5B, you may replace with it and may use the simple shaft body which connects the transmission case 2 and the hinge main body 41 so that rotation is possible. The same applies to the second hinges 6A and 6B.

  As shown in FIGS. 9 and 10, the first hinge 5 </ b> A has a first cylindrical body (first fixing means) 51. One end portion of the first shaft body 52 is rotatably inserted into the central portion of the bottom portion 51a of the cylindrical body 51. The first cylinder body 51 is prevented from coming off from the first shaft body 52 by the head portion 52 a of the first shaft body 52 abutting against the bottom portion 51 a. A first disc 53 and a first rotating member 54 are extrapolated to the other end of the first shaft body 52. The first disc 53 is fixed to the first shaft body 52. The first rotating member 54 is fitted to the first shaft body 52 so as not to rotate. Therefore, the first rotation member 54 is rotatably connected to the first cylinder 51 via the first shaft body 52. The first rotation member 54 is prevented from coming off from the first shaft body 52 by abutting against the first disc 53.

  A first movable member 55 is fitted in an intermediate portion of the first shaft body 52 so as to be rotatable and movable. The first movable member 55 is connected to the first cylinder 51 so as not to rotate and to be movable in the axial direction of the first cylinder 51 (first rotation axis direction). Accordingly, the first movable member 55 rotates relative to the first rotating member 54 together with the first cylindrical body 51.

  A first coil spring (first urging means) 56 is externally inserted in an intermediate portion of the first shaft body 52 located between the bottom 51 a of the first cylinder 51 and the first movable member 55. The first coil spring 56 biases the first movable member 55 toward the first rotating member 54 side.

  As shown in FIG. 9, the first cylindrical body 51, the first shaft body 52, the first rotating member 54, and the first movable member 55 have their respective axes aligned with each other and the first rotating axis L1. It is arranged in the state of letting. One end of the first cylinder 51 is inserted into the connection hole 2d formed in the transmission case 2 so as not to rotate, and the other end is rotatably fitted into the connection hole 41c formed in the hinge body 41. Has been. Thereby, the transmission case 2 and the hinge main body 41 are connected so as to be rotatable about the first rotation axis L1. The first rotation member 54 is fitted in the connection hole 41c so as not to rotate. Therefore, when the hinge main body 41 rotates with respect to the transmission case 2, the first rotating member 54 rotates with respect to the first cylindrical body 51 and the first movable member 55.

  The first hinge 5A further stops the hinge body 41 with respect to the transmission case 2 at a first starting position, a first intermediate position, and a first terminal position with a predetermined amount of force. It has a configuration.

  That is, a pair of first spheres (first projecting portions) 57 and 57 are provided on a surface of the first movable member 55 facing the first rotating member 54 in a state in which a part thereof is projected. The pair of spheres 57 and 57 are abutted against the first rotating member 54 by the first coil spring 56. The pair of first spheres 57, 57 are arranged 180 degrees apart in a circumferential direction (hereinafter simply referred to as a circumferential direction) centered on the first rotation axis L1. Moreover, the first sphere 57 is provided so as to be movable in a radial direction of a circle centered on the first rotation axis L1 (hereinafter simply referred to as a radial direction).

  As shown in FIGS. 10 and 11, a pair of first start end cam surfaces (first start end conversion portions) 54 a and 54 a and a pair of first start members 54 are provided on the surface of the first rotating member 54 facing the first movable member 55. 1st end cam surface (1st end conversion part) 54b, 54b and a pair of 1st engagement recessed parts 54c, 54c are formed.

  The pair of first start cam surfaces 54a, 54a are disposed 180 degrees apart from each other in the circumferential direction on a circumference centered on the first rotation axis L1. Moreover, the first start end cam surfaces 54a and 54a are arranged so that the first spheres 57 and 57 abut when the hinge body 41 is located at the first start end position. The first start end cam surface 54a is inclined so as to approach the first movable member 55 in the direction from the first end position toward the first start end position (the arrow A direction in FIGS. 11 and 12). Yes. Therefore, when the first sphere 57 hits the first start end cam surface 54a, the biasing force of the first coil spring 56 biases the hinge body 41 in the direction from the first end position toward the first start end position. Is converted to The hinge main body 41 is maintained at the first start position by this rotational biasing force. Moreover, the first start end cam surface 54a has a predetermined length in the circumferential direction, and when the hinge body 41 rotates from the first end position toward the first start end position, the first start end cam surface 54a has a predetermined length. It is configured to come into contact with the first sphere 57 when it is rotated to a front position by a predetermined angle (for example, 10 °). Therefore, when the hinge body 41 is rotated within a predetermined angular range (hereinafter referred to as a position near the first start end) from the first start position toward the first end position, the hinge body 41 is moved to the first coil spring. The first biasing force is rotated to the first starting end position by the rotating biasing force having a predetermined magnitude based on the biasing force 56 and maintained at the first starting end position. Moreover, when the hinge main body 41 is rotated to the first start end position, the hinge main body 41 collides with the transmission case 2, so that the hinge main body 41 is stopped at the first start end position with a click feeling.

  The pair of first terminal cam surfaces 54b, 54b are disposed 180 degrees apart from each other in the circumferential direction on a circumference centered on the first rotation axis L1. Moreover, the second end cam surfaces 54b, 54b are substantially in contact with the pair of first start end cam surfaces 54a, 54a in the circumferential direction, and are substantially in contact with the outside of the pair of first start end cam surfaces 54a, 54a in the radial direction. It is arranged like that. The first end cam surfaces 54b and 54b form a pair with the first start end cam surfaces 54a and 54a that are 180 degrees apart in the circumferential direction, and the first end cam surface 54b and the first start end cam surface of each set. 54a is connected by a first guide groove 55d extending in a spiral between them. Therefore, when the hinge body 41 rotates from the first start position to the first end position, the first sphere 57 moves from the first start end cam surface 54a to the first end cam surface 54b through the first guide groove 54d. It abuts against the first terminal cam surface 54b.

  Thus, when the hinge body 41 rotates to the first terminal position, the first terminal cam surface 54b hits the first sphere 57, but the first terminal cam surface 54b is moved from the first starting position to the first terminal position. It is inclined so as to approach the first movable member 55 in the direction approaching the position (the direction of arrow B in FIGS. 11 and 12). Therefore, when the first sphere 57 hits the first end cam surface 54b, the urging force of the first coil spring 56 urges the hinge body 41 in the direction from the first start position to the first end position. Is converted to The hinge main body 41 is maintained at the first terminal position by this rotational biasing force. In addition, the first end cam surface 54b has a predetermined length in the circumferential direction, and when the hinge body 41 rotates from the first start end position toward the first end position, the first end cam surface 54b has a predetermined length. It is configured to come into contact with the first sphere 57 when it is rotated to a front position by a predetermined angle (for example, 10 °). Therefore, when the hinge body 41 is rotated within a predetermined angular range (hereinafter referred to as a position near the first end) from the first end position toward the first start end position, the hinge body 41 is moved to the first coil spring. The rotary biasing force having a predetermined magnitude based on the biasing force of 56 is rotated to the first terminal position and maintained at the first terminal position. Moreover, when the hinge main body 41 is rotated to the first terminal position, the hinge main body 41 collides with the transmission case 2, so that the hinge main body 41 is stopped at the first terminal position with a click feeling.

  The first engaging recess 54 c is configured by a spherical surface having the same radius of curvature as the spherical surface forming the outer peripheral surface of the first sphere 57. Therefore, a part of the first sphere 57 protruding from the first movable member 55 can be fitted into the first engagement recess 54c. The first engaging recess 54c is disposed at substantially the center of the first guide groove 54d so as to be positioned at the center of the pair of first start cam surface 54a and first end cam surface 54b. Therefore, when the hinge body 41 is rotated 90 ° from the first start position or the first end position and reaches the first intermediate position, the first sphere 57 is fitted into the first engagement recess 54c. As a result, the hinge body 41 is stopped with a click feeling with a predetermined amount of force at the first intermediate position.

  The first hinge 5B paired with the first hinge 5A is disposed symmetrically with the first hinge 5A. Therefore, if the same first hinge 5B as the first hinge 5A is used, the first hinge 5B is configured such that when the hinge body 41 is located at the first start position, the hinge body 41 is moved to the first start end. When the hinge main body 41 is located at the first terminal position, the hinge main body 41 is rotated from the first terminal position toward the first starting position. I will be energized. In order to prevent such a situation, a first rotating member 54 'is used in the first hinge 5B in place of the first rotating member 54 of the first hinge 5A. In the first rotating member 54 ′, when the hinge body 41 is located at the first start position, the hinge body 41 is urged to rotate in the direction from the first end position toward the first start position. When the main body 41 is located at the first end position, the first start end cam surface 55a and the first first end cam surface 55a can be urged to rotate in a direction from the first end position toward the first start end position. The end cam surface 55b is arranged symmetrically with those of the first hinge 5A. Other configurations of the first hinge 5B are the same as those of the first hinge 5A.

  The second hinge 6A includes the first cylinder 51, the first shaft 52, the first disc 53, the first rotating member 54, the first movable member 55, the first coil spring 56, and the first of the first hinge 5A. As a member corresponding to each of the spheres 57, a second cylinder (second fixing member) 61, a second shaft body 62, a second disc 63, a second rotating member 64, a second movable member 65, a second coil spring. (Second biasing means) 66 and a second sphere 67 are provided. These members are configured in the same manner as the corresponding members of the first hinge 5 </ b> A except for the second rotating member 64.

  The first cylinder 51 and the first rotating member 54 of the first hinge 5A are connected to the transmission case 2 and the hinge body 41 so as not to rotate, respectively, whereas the second cylinder 61 is used in the second hinge 6A. The second rotating member 64 is connected to the hinge body 3 and the receiving case 3 so as not to be movable. For this reason, if the same thing as the 1st rotation member 54 is used as the 2nd rotation member 64, when the reception case 3 is located in the 2nd start position, the 2nd hinge 6A will place the reception case 3 in the 2nd start position. When the receiving case 3 is located at the second terminal position, the receiving case 3 is rotationally biased toward the second starting position. Therefore, in the second hinge 6A, a second rotating member 64 different from the first rotating member 54 of the first hinge 5A is used.

  That is, as shown in FIG. 13, in the second rotating member 64, the second starting end cam surface (second starting end converting portion) that abuts against the second sphere 67 when the receiving case 3 rotates to the second starting end position. The inclination direction of 64a is set to be opposite to the inclination direction of the first start end cam surface 54a. That is, the second start cam surface 64a is inclined so as to approach the second movable member 65 from the second end position toward the second start position (in the direction of arrow C in FIG. 13). . Therefore, when the receiving case 3 is located at the second starting end position, the second hinge 6A urges the receiving case 3 to rotate in the direction from the second end position toward the second starting end position to reach the second starting end position. maintain. The second end cam surface (second end conversion portion) 64b approaches the second movable member 65 from the second start end position toward the second end position (in the direction of arrow D in FIG. 13). It is tilted. Therefore, when the receiving case 3 is located at the second terminal position, the second hinge 6A urges the receiving case 3 in the direction from the second starting position toward the second terminal position to move to the second terminal position. maintain.

  The second start end cam surface 64a does not hit the second sphere 67 only at the second start end position, and is a range from the second start end position toward the second end position side by a predetermined angle (hereinafter referred to as a second start end vicinity position). .) Also hits the second sphere 67. Therefore, when the reception case 3 is positioned in the vicinity of the second start end, the reception case 3 is rotated to the second start end position by the second hinge 6A. Similarly, the second end cam surface 64b does not hit the second sphere 67 only at the second end position, and is a range that is directed from the second end position toward the second start end position by a predetermined angle (hereinafter, near the second end position). (Referred to as a position) also hits the second sphere 64. Therefore, when the reception case 3 is positioned in the vicinity of the second end, the reception case 3 is rotated to the second end position by the second hinge 6A. Moreover, when the reception case 3 reaches the second start end position and the second end position, the reception case 3 abuts against the hinge main body 41 and is stopped at each position with a click feeling.

  The second rotation member 64 is provided with a second engagement recess 64c instead of the first engagement recess 54c. The second engagement recess 64c is arranged and configured in the same manner as the first engagement recess 54c, except that the depth is shallower than the depth of the first engagement recess 54c. The second start end cam 64a and the second end cam 64b are connected by a second guide groove 64d, and the second engagement recess 64c is disposed at the center of the second guide groove 64d.

  The second hinge 6B is configured symmetrically with the second hinge 6A in the same manner that the first hinge 5B is configured symmetrically with respect to the first hinge 5B. Therefore, in the second hinge 6B, a second rotating member 64 ′ is used instead of the second rotating member 64 of the second hinge 6A.

Inclination angles of the first start end cam surface 54a, the first end cam surface 54b, the second start end cam surface 64a, and the second end cam surface 64b (inclination angles with respect to a plane orthogonal to the first and second rotation axes L1 and L2) ) Are α1, α2, β1, and β2, respectively, and the angle inclination angles α3 and β3 at the open ends (the upper ends in FIGS. 12 and 13) of the first engagement recess 54c and the second engagement recess 64c are the hinge body 41. In order to achieve the above-described rotation order of the receiving case 3, the inclination angles α <b> 1 to β <b> 3 are set to satisfy the following expression.
α1 <β1
α2> β2
α2 <β3
α3> β1
α3> β3

  Now, since the hinge body 41 is located at the first starting end position and the receiving case 3 is located at the second starting end position, the receiving case 3 is located at the folding position with respect to the transmitting case 2. To do. At this time, as shown in FIG. 12, the first sphere 57 abuts against the first start end cam surface 54a, and as shown in FIG. 13, the second sphere 67 abuts against the second start end cam surface 64a. If the reception case 3 is opened and rotated from the folding position toward the reverse folding position, since α1 <β1, the rotation is performed to bias the reception case 3 from the second terminal position toward the first starting position. The dynamic biasing force is larger than the rotational biasing force that biases the hinge body 41 from the first terminal position toward the first start position. Accordingly, the reception case 3 maintains a stopped state at the second start end position with respect to the hinge main body 41, and the hinge main body 41 is centered on the first rotation axis L1 with respect to the transmission case 2 from the first start end position to the first end position. Open to the side. Accordingly, the first sphere 57 moves relative to the first rotating member 54 in the direction of arrow A in FIG.

  When the hinge main body 41 is opened and rotated from the first starting end position to the first intermediate position, the first spherical body 57 is fitted into the first engaging recess 54c as shown in FIG. As a result, the hinge body 41 is stopped at the first intermediate position with a click feeling with a force of a predetermined magnitude (see FIG. 4). Thereafter, when the receiving case 3 is further rotated to open, since α3> β1, the hinge main body 41 remains stopped at the intermediate position, and the receiving case 3 is in the second rotation axis L2 with respect to the hinge main body 41. Is pivoted from the second starting position toward the second intermediate position. Accordingly, the second sphere 67 moves relative to the second rotating member 64 in the direction of arrow C in FIG. When the reception case 3 is pivoted open from the second starting end position to the second intermediate position, the second sphere 67 is fitted into the second engaging recess 64c as shown in FIG. As a result, the receiving case 3 is stopped at a second intermediate position with a click feeling with a predetermined magnitude (see FIG. 5).

  In a state where the hinge body 41 is located at the first intermediate position and the reception case 3 is located at the second intermediate position, when the reception case 3 is further opened and rotated, α3> β3. The main body 41 maintains the stopped state at the first intermediate position, and the receiving case 3 rotates open from the second intermediate position toward the second terminal position. When the reception case 3 rotates to a position that is a predetermined angle before the second terminal position, the second sphere 67 abuts against the second terminal cam surface 64b as shown in FIG. As a result, the receiving case 3 is urged to rotate toward the second terminal position. The reception case 3 rotates and stops until it abuts against the hinge body 41. Accordingly, the reception case 3 is stopped at the second terminal position with a click feeling with a predetermined magnitude of force (see FIG. 6).

  If the receiving case 3 is further opened and rotated, the receiving case 3 cannot be opened and rotated with respect to the hinge body 41, and therefore the hinge body 41 is opened and rotated from the first intermediate position toward the first terminal position. To do. When the hinge main body 41 is rotated to a position just before the first end position by a predetermined angle, as shown in FIG. 17, the first sphere 57 hits the first end cam surface 54b. As a result, the hinge body 41 is urged to rotate toward the first terminal position. The hinge body 41 rotates and stops until it hits the transmission case 2. The position of the reception case 3 at this time is the reverse folding position shown in FIG. Accordingly, the reception case 3 is stopped at the reverse folding position with a click feeling with a predetermined magnitude of force.

  When the reception case 3 is located at the reverse folding position, as shown in FIG. 16, the first sphere 57 abuts against the first terminal cam surface 54b, and as shown in FIG. 2 It abuts against the end cam surface 64b. At this time, since the inclination angle α2 of the first end cam surface 54b and the inclination angle β2 of the second end cam surface 64b are set so as to satisfy α2> β2, the reception case 3 is closed from the reverse folding position. In order to rotate, the receiving case 3 is first closed and rotated from the second terminal position to the second intermediate position (see FIG. 8).

  When the receiving case 3 is rotated to the second terminal position, the second sphere 67 is fitted into the second engaging recess 64c as shown in FIG. Then, since β3> α2, the receiving case 3 is maintained in a stopped state, and the hinge body 41 is closed and rotated from the first terminal position to the first intermediate position. When the hinge body 41 reaches the first intermediate position, as shown in FIG. 14, the first sphere 57 is fitted into the first engagement recess 54c. Then, since α3> β3, the hinge body 41 is maintained in a stopped state, and the receiving case 3 is closed and rotated from the second intermediate position. When the reception case 3 reaches a position in front of the second start end position by a predetermined angle, the second sphere 67 strikes the second start end cam surface 64a. As a result, the reception case 3 is urged to rotate toward the second starting end position. Then, as shown in FIG. 4, the reception case 3 hits the hinge body 41 and stops. Accordingly, the reception case 3 is stopped at a second start position with a click feeling with a predetermined magnitude of force. Thereafter, the hinge body 41 is rotated from the first intermediate position to the first start position. When the hinge body 41 is rotated to a position just before the first start position by a predetermined angle, the first sphere 57 abuts against the first start cam surface 54a. As a result, the hinge body 41 is urged to rotate toward the first starting end position. Then, the hinge body 41 hits the transmission case 2 and stops. Therefore, the hinge main body 41 is stopped at a first starting position with a click feeling with a predetermined amount of force. The receiving case 3 is closed and turned to the second starting end position, and the hinge body 41 is turned to the first starting end position, whereby the receiving case 3 is returned to the folding position.
