In order to solve the above problem, a fourth aspect of the present invention includes first and second housings and a movable member, and one end portion of the movable member is disposed on the first path on the first housing. The other end of the movable member that is movable and pivotally connected about the first rotation axis and is spaced apart from the one end of the movable member in a direction perpendicular to the first rotation axis, The second casing is connected to the first casing so as to be movable on a second path and rotatable about a second rotation axis parallel to the first rotation axis, and the second casing is connected to the movable member. The first and second paths are non-rotatably connected, and the first and second paths are not parallel to each other when the first and second paths are viewed from the first rotation axis direction.
In this case, the first casing is provided with first and second guide portions extending on the first and second paths, respectively, and one end portion of the movable member moves to the first guide portion in the longitudinal direction thereof.

Since the second housing moves in the horizontal direction, for example, when the second housing is rotated with respect to the first housing so that the longitudinal direction of the second housing is orthogonal to the longitudinal direction of the first housing. It is also possible to position the second housing at the center in the longitudinal direction of the first housing.

The best mode for carrying out the present invention will be described below with reference to the drawings.
1 to 24 show a first embodiment of a portable game machine (portable device) 1 according to the present invention. As shown in FIGS. 1 to 15, the game machine 1 includes a first housing 2, a second housing 3, and a hinge device 4.

  The first housing 2 is composed of two halves 2A and 2B fixed to each other, and is formed in a hollow flat plate shape having a substantially rectangular shape in plan view. Various operation buttons (not shown) are provided on the upper surface (rotation preventing means) 2 a of the first housing 2. The first housing 2 is formed with a recess 2c penetrating from the upper surface 2a to the lower surface 2b. The recess 2c is arranged at the center of one end (the upper end in FIGS. 1 and 9) 2d of the first casing 2 in the width direction. The recess 2 c has a rectangular shape in plan view, and is formed with its longitudinal direction facing the longitudinal direction of the first housing 2. A hinge device 5 to be described later is disposed in the recess 2c.

  The 2nd housing | casing 3 is formed in flat form, and has the same planar view shape as the 1st housing | casing 2 except the point where the recessed part 2c is not formed. A liquid crystal display unit 3 c is provided on the upper surface 3 a of the second housing 3. The second housing 3 is arranged with its lower surface (rotation prevention means) 3b facing the upper surface 2a of the first housing 2, and maintains the state with respect to the first housing 2 The second housing 3 is connected to the first housing 2 via the hinge device 4 so as to be able to be rotated and displaced so that the second housing 3 rotates while being translated in a substantially horizontal plane. The rotation range of the second housing 3 in the horizontal plane is limited by the hinge device 4 to a range from the initial position to the end position through the intermediate position.

  As shown in FIGS. 1 to 4, when the second housing 3 is rotated to the initial position, the entire second housing 3 (except for the portion corresponding to the recess 2 c) is moved up and down with respect to the first housing 2. Overlapping. Therefore, when the game machine 1 is viewed from above (overlapping direction) when the second housing 3 is located at the initial position, the entire first housing 2 is covered by the second housing 3, and only the second housing 3 is present. Become invisible. The second housing 3 reaches an intermediate position when the second housing 3 is rotated 90 ° counterclockwise in FIG. 1 while maintaining the state in which the lower surface 3b is opposed to the upper surface 2a of the first housing 2. As shown in FIGS. 5 to 8, the second casing 3 rotated to the intermediate position has its longitudinal direction oriented in a direction orthogonal to the longitudinal direction of the first casing 2, and the longitudinal direction of the first casing 2 is Located in the center. Moreover, the second casing 3 has one end in the longitudinal direction superimposed on the first casing 2 and the other end in the longitudinal direction is projected outward from the first casing 2. When the second casing 3 is rotated 90 ° counterclockwise in FIG. 5 from the intermediate position, that is, when it is rotated 180 ° counterclockwise from the initial position, the second housing 3 reaches the end position. As shown in FIGS. 9 to 12, the second housing 3 rotated to the end position is located at the same position as the first housing 2 in the longitudinal direction. However, the second housing 3 is located at a different position with respect to the first housing 2 in the short direction. That is, the second housing 3 has one end portion in the short direction (the upper end portion in FIG. 1 and the lower end portion in FIG. 9) 3d in the vertical direction with the one end portion 2 d in the short direction of the first housing 2. The opposite end 3e in the short direction is separated from the first housing 2 in the direction from the other end 2e toward the one end 2d. The second housing 3 reaches the intermediate position when it is rotated 90 ° clockwise from the end position, and reaches the initial position when it is further rotated 90 °.

  When the second housing 3 is located at the initial position, the intermediate position, and the end position, the hinge device 4 prevents the first housing 2 from rotating in the horizontal direction with a click feeling with a predetermined amount of force. Be made. In addition, when the second housing 3 is located at the initial position and the terminal position, the lower surface 3 b of the second housing 3 is pressed against the upper surface 2 a of the first housing 2. Details of this point will be described later.

  When the second housing 3 is located at the terminal position, the second housing 3 pivots up and down around the third pivot axis L3 extending horizontally along the longitudinal direction of the first housing 2 with respect to the first housing 2. It is possible. The rotation range of the second housing 3 in the vertical direction is limited between the parallel position and the inclined position. As shown in FIGS. 10 to 12, the second housing 3 is parallel to the first housing 2 when positioned in the parallel position. Therefore, when the second casing 3 is rotated to the parallel position, the second casing 3 can be rotated from the terminal position to the initial position side. As shown in FIGS. 13 and 14, the tilted position is a predetermined tilt angle in the counterclockwise direction of FIG. 10 about the third rotation axis L3 from the parallel position of the second housing 3 (in this embodiment). This is the position when rotated by approximately 20 °. Therefore, when the second housing 3 is located at the tilt position, the second housing 3 is tilted by the tilt angle with respect to the first housing 2. When the second housing 3 is located at the inclined position, the second housing 3 cannot be rotated in the horizontal direction. As will be described later, the second housing 3 is also rotated in the vertical direction with respect to the first housing 2 via the hinge device 4. In addition, the second housing 3 is prevented from rotating in the vertical direction with a click feeling by a predetermined amount of force at the parallel position and the inclined position by the hinge device 4.

  The hinge device 4 that connects the second housing 3 to the first housing 2 so as to be rotatable in the vertical direction and the horizontal direction will be described. As shown in FIGS. 15 to 24, the hinge device 4 includes a housing (hinge body). ) 5. The housing 5 is constituted by a main body 6, a rail plate 7 and a back plate 8. The main body 6 has a rectangular parallelepiped box shape with a small thickness in the vertical direction, and its lower surface is open. Each of the rail plate 7 and the back plate 8 is formed in a flat plate shape, and the shape in plan view is substantially the same as the lower surface portion of the main body portion 6. And the rail plate 7 and the back plate 8 are being fixed to the lower surface part of the main-body part 6 in the order. Thereby, the housing 5 which makes | forms a hollow box shape is comprised. Upper and lower cosmetic boxes 9 and 10 are fixed to the outside of the housing 5.

  The housing 5 configured as described above is disposed in the recess 2c of the first casing 2 so as to be rotatable about the third rotation axis L3. That is, at both ends in the longitudinal direction of the housing 5, one end of each of the connecting arms (first mounting portions) 11 and 12 is provided so as to be rotatable about the third rotation axis L <b> 3. The other end portions of the connecting arms 11 and 12 are fixed to the first casing 2. Thereby, the housing 5 and the decorative cases 9 and 10 are connected to the first casing 2 so as to be rotatable in the vertical direction about the third rotation axis L3. As will be described later, the housing 5 rotates in the vertical direction integrally with the second casing 3. Accordingly, the vertical rotation range of the housing 5 is the same as the vertical rotation range of the second housing 3, and the parallel position shown in FIGS. 9 to 12 and the inclination shown in FIGS. 13 and 14. Regulated between position. The horizontal positions of the housing 5 and the second housing 3 are regulated by the contact surfaces 2f and 10a formed at the lower ends of the first housing 2 and the lower decorative box 10 abutting each other. The inclined positions of the housing 5 and the second housing 3 are regulated by the inclined surface 3f formed on the lower surface of the one end 3d of the second housing 3 abutting against the upper surface 2a of the first housing 2. In addition, as described above, the second housing 3 rotates about the third rotation axis L3 only when the second housing 3 is located at the terminal position, at a position other than the terminal position. Since the lower surface 3b of the second housing 3 abuts against the upper surface of the first housing 2, the rotation of the second housing 3 around the third rotation axis L3 is prevented. Therefore, in this embodiment, the rotation preventing means is constituted by the upper surface 2 a of the first housing 2 and the lower surface 3 b of the second housing 3.

  A click mechanism (not shown) is provided between at least one of the connecting arms 11 and 12 and the housing 5. The click mechanism rotates the housing 5 from the inclined position toward the horizontal position when the housing 5 is positioned between the horizontal position and a position away from the horizontal position by a predetermined angle (for example, 5 °). The abutting surface 10a is abutted against the abutting surface 2f by moving and energizing. Thus, the housing 5 is stopped at a horizontal position with a click feeling with a predetermined amount of force. The click mechanism also moves the housing 5 from the horizontal position toward the inclined position when the housing 5 is positioned between the inclined position and a position away from the inclined position by a predetermined angle (for example, 5 °). The inclined surface 3f is abutted against the upper surface 2a by turning and energizing. Thus, the housing 5 is stopped at a tilted position with a click feeling with a predetermined amount of force. Various known mechanisms can be employed as the click mechanism that performs such an action.

  The main body 6 of the housing 5 is formed with an upper guide hole (second guide) 6a that vertically penetrates the upper wall portion. The upper guide hole 6 a is formed as a long hole extending along the longitudinal direction of the main body 6. A guide member 30 that extends annularly along the upper guide hole 6a is fitted and fixed to the upper guide hole 6a. The rail plate 7 is formed with a lower guide hole (first guide portion) 7a penetrating therethrough. The lower guide hole 7 a extends in a direction intersecting with the longitudinal direction of the rail plate 7. Therefore, the lower guide hole 7a is not parallel to the upper guide hole 6a. That is, the lower guide hole 7a is inclined with respect to the upper guide hole 6a. The back plate 8 is formed with a slide hole 8a penetrating up and down. The slide hole 8a is disposed at the same position as the lower guide hole 7a in plan view. The length of the slide hole 8a is substantially the same as that of the lower guide hole 7a. However, as shown in FIG. 23, the width of the slide hole 8a is wider than the width of the lower guide hole 7a. As shown in FIG.22 and FIG.23, the protrusion part 8b extended over the perimeter is formed in the upper end part of the internal peripheral surface of the slide hole 8a. By forming the protruding portion 8b, the width of the upper end portion of the slide hole 8a is substantially the same as the width of the lower guide hole 7a.

  As shown in FIGS. 19 to 24, the first movable plate 13 is movably mounted on the upper surface of the rail plate 7. Rollers 14, 14 whose axes are directed in the vertical direction are rotatably connected to both ends of the lower surface of the first movable plate 13 via pins 15, 15. Each roller 14 is inserted into the lower guide hole 7a of the rail plate 7 so as to be able to roll. Thereby, the 1st movable plate 13 moves along the longitudinal direction of the lower guide hole 7a. In other words, the moving direction of the first movable plate 13 is regulated in the longitudinal direction by the lower guide hole 7a.

  The second movable plate 16 is accommodated in the slide hole 8a of the back plate 8 so as to be movable in the longitudinal direction of the slide hole 8a. The second movable plate 16 is fixed to the lower end portion of the pin 15 that passes through the first movable plate 13 and the roller 14. Thereby, the 1st, 2nd movable plates 13 and 16 move integrally. In addition, the first and second movable plates 13 and 16 sandwich the protruding portion 8b vertically so that the first and second movable plates 13 and 16 cannot move in the vertical direction. In order to make the second movable plate 14 move smoothly, the back plate 8 is made of a material having a small frictional resistance such as a fluororesin.

  A movable member 17 is accommodated in the housing 5 so as to be movable and rotatable. The movable member 17 includes a disk portion 18, a connecting plate portion 19, a cylindrical portion 20, and a mounting plate portion (second mounting portion) 21 that are integrally formed with each other.

  The disc portion 18 is rotatably fitted to the outer periphery of a shaft body 22 that is fixed upright at the center portion with its axis line oriented in the vertical direction. Thus, one end portion (disk portion 18) of the movable member 17 is connected to the housing 5 so as to be movable in the longitudinal direction of the lower guide hole 7 a and to be rotatable about the axis of the shaft body 22. The axis of the shaft body 22 is the first rotation axis L1. The first rotation axis L <b> 1 is orthogonal to the front surface 3 a of the second housing 3. Therefore, when the second housing 3 is parallel to the first housing 2, the second housing 3 is also orthogonal to the front surface 2 a of the first housing 2. In addition, the first rotation axis L1 moves as the movable member 17 moves in the longitudinal direction of the lower guide hole 7a. The disc portion 18 is fitted to the outer peripheral surface of the shaft body 22 so as to be movable in the axial direction. Accordingly, the movable member 17 is movable in the first rotation axis L1 direction with respect to the housing 5.

  The connecting plate portion 19 extends horizontally from one side portion of the upper surface of the disc portion 18 toward the radially outer side of the disc portion 18. A cylindrical portion 20 is provided on the upper surface of the connecting plate portion 19 with its axis line directed vertically. The cylindrical portion 20 is disposed at a substantially central portion in the longitudinal direction of the connecting plate portion 19. Thereby, the axis of the cylindrical portion 20 is separated in the direction orthogonal to the first rotation axis L1. Moreover, the axis of the cylindrical portion 20 is parallel to the first rotation axis L1.

  The cylindrical portion 20 is inserted into the upper guide hole 6a via the guide member 30 so as to be movable in the longitudinal direction of the upper guide hole 6a and to be rotatable. As a result, the other end portion (cylindrical portion 20) of the movable member 17 that is separated from the one end portion of the movable member 17 in the direction orthogonal to the first rotation axis L <b> 1 is longitudinal with respect to the housing 5 It is connected so that it can move to the center and can rotate around the axis of the cylindrical portion 20. The axis of the cylindrical portion 20 is the second rotation axis L2. Therefore, the second rotation axis L2 is parallel to the first rotation axis L1, and moves with the movement of the movable member 17 in the longitudinal direction of the upper guide hole 6a.

  Since the cylindrical portion 20 and the disc portion 18 are movably inserted into the upper and lower guide holes 6a and 7a, the movable member 17 is guided by the upper and lower guide holes 6a and 7a (the movement direction and the movement amount are regulated). While moving in the horizontal direction (direction orthogonal to the first and second rotation axes L1 and L2). Here, the upper guide hole 6a and the lower guide hole 7a both extend in the horizontal direction, but are inclined and non-parallel to each other. Therefore, when the movable member 17 moves in the horizontal direction, the disk portion 18 and the cylindrical portion 20 are rotated with respect to the housing 5 about the first and second rotation axes L1 and L2. As a result, the entire movable member 17 rotates while being translated in the horizontal direction so that the posture of the movable member 17 in plan view changes. In other words, when the movable member 17 rotates, the cylindrical portion 20 and the disc portion 18 move in the longitudinal direction in the upper and lower guide holes 6a and 7a, respectively, while the first and second rotation axes L1 and L2 are moved. Rotate around the center. As is clear from this, in this embodiment, the lower guide hole 7a is the first path, and the upper guide hole 6a is the second path. The amount of movement of the movable member 17 in the horizontal direction and the amount of rotational displacement are determined by the positions and inclination angles of the upper and lower guide holes 6a, 7a and the distance between the first and second rotational axes L1, L2.

  A mounting plate portion 21 is provided on the outer peripheral surface of the upper end portion protruding upward from the upper guide hole 6a of the cylindrical portion 20. The second housing 3 is fixed to the mounting plate portion 21. Therefore, the second housing 3 behaves integrally with the movable member 17. In this case, since the movable member 17 rotates integrally with the housing 5 with respect to the third rotation axis L3, the second case 3 rotates about the third rotation axis L3 with respect to the first case 2. In doing so, the movable member 17, the housing 5, and the connecting arms 11, 12 rotate together.

  On the other hand, the movable member 17 moves with respect to the housing 5 in the horizontal direction along the upper and lower guide holes 6a and 7a, and rotates about the first and second rotation axes L1 and L2. 3 is moved and rotated in the horizontal direction with respect to the first housing 2 and the housing 5 together with the movable member 17 when moving and rotating in the horizontal direction. Therefore, horizontal movement and rotational displacement of the second housing 3 are restricted by the upper and lower guide holes 6 a and 7 a and the movable member 17. In other words, the cylindrical portion 20 and the disc portion 18 of the movable member 17 move in the upper and lower guide holes 6a and 7a as follows in accordance with the horizontal movement and rotational displacement of the second housing 3.

  That is, it is assumed that the second housing 3 is now in the initial position. At this time, as shown in FIGS. 25 and 26, the disc portion 18 is positioned substantially at the center portion of the lower guide hole 7a, and the cylindrical portion 20 is one end portion of the upper guide hole 6a (the right end portion in FIG. One end of each of the upper and lower guide holes 6a and 7a is referred to as a right end, and the other end is referred to as a left end. For convenience of illustration and description, the first dust-proof seal 30 is omitted in FIGS. 25 to 32. When the second housing 3 is rotated counterclockwise from the initial position toward the intermediate position, the vertical distance in FIG. 25 between the first and second rotation axes L1 and L2 becomes longer. Thus, the cylindrical portion 20 and the disc portion 18 move to the left end side in the upper and lower guide holes 6a and 7a, respectively. 27 and 28 show a state in which the second housing 3 is rotated by 30 ° with respect to the first housing 2 and the housing 5.

  29 and 30 show a state where the second housing 3 is located at the intermediate position. At this time, the cylindrical portion 20 and the disc portion 18 are located at the left end portions of the upper and lower guide holes 6a and 7a. If the second casing 3 is further rotated counterclockwise from the intermediate position toward the end position, the vertical distance in FIG. 29 between the first and second rotation axes L1 and L2 is shortened. The part 20 and the disk part 18 move in the upper and lower guide grooves 6a, 7a toward the right end part (see FIGS. 31 and 32). When the second housing 3 rotates to the end position, the cylindrical portion 20 and the disc portion 18 abut against the right end portions of the upper and lower guide holes 6a and 7a, and the second housing 3 further rotates counterclockwise. I can't do that. That is, the end position of the second housing 3 is restricted by the cylindrical portion 20 and the disc portion 18 abutting against the right end portions of the upper and lower guide holes 6a and 7a.

  When the second housing 3 located at the end position is rotated clockwise toward the initial position, the cylindrical portion 20 and the disc portion 18 move in the upper and lower guide holes 6a and 7a in the opposite direction to the above. To do. When the second casing 3 rotates to the initial position, the cylindrical portion 20 hits the right end portion of the upper guide hole 6a and cannot move to the right any further.
