Specifically, the stopper receiving portion 55 is an inner wall that is erected upward in the width direction at an intermediate position in the front-rear direction of the main body 22. The stopper receiving portion 55 is connected to the side walls 22 </ b> A and 22 </ b> A on both sides in the width direction of the main body 22. The stopper portion 54 is disposed in a front portion of the main body 22 divided by the stopper receiving portion 55. The length of the stopper portion 54 in the front-rear direction is shorter than the length of this portion in the front-rear direction, and is movable between the front end portion of the main body 22 and the stopper receiving portion 55 in the front-rear direction.

  The angle adjustment unit 5 is provided on the back surface of the display unit 4 along the rotation direction of the display unit 4 and the guide surface 56 according to the rotation of the display unit 4. And a guide receiving portion 57 that moves the guide surface 56 while maintaining the contact state.

  Furthermore, the angle adjusting unit 5 includes an elastic member 58 that is connected between the protruding portion 51 and the main body 22 and applies a restoring force f that pulls the protruding portion 51 in a direction that causes the display unit 4. The elastic member 58 is a spring, for example. For example, as shown in FIGS. 4 and 5, the elastic member 58 is installed on the outside of the side wall 22 </ b> A of the main body 22.

  Next, with reference to FIGS. 6-8, operation | movement of the terminal device 1 which concerns on this embodiment is demonstrated. FIG. 6 is a side view of the terminal device 1 showing a state in which the display unit 4 is tilted. FIG. 7 is a side view of the terminal device 1 showing a state in which the display unit 4 is raised to the midway position. FIG. 8 is a side view of the terminal device 1 showing a state in which the display unit 4 is raised to the maximum angular position.

  When the display unit 4 shown in FIG. 6 is in a tilted state, the display unit 4 is disposed along the opening of the cover 21. The front end portion of the display unit 4 is in contact with the rear end portion of the upper surface portion 3. The edge 4 </ b> A of the display unit 4 is in contact with the upper surface part 3, and there is no gap between the upper surface part 3 and the display unit 4. In this state, the protrusion 51 is positioned at the front end of the guide groove 52, and the stopper portion 54 is also positioned at the front end of the movable range in the front-rear direction. The guide receiving portion 57 is in contact with the upper end of the guide surface 56. The angle formed by the two arms 53A and 53B of the torque stay 53 in the hinge assembly 53C is the minimum angle. The torque stay 53 maintains this angle by the frictional resistance of the hinge assembly 53C.

  6, when an external force F greater than the frictional resistance of the hinge assembly 53C is applied in the direction in which the display unit 4 is raised, the two arms 53A and 53B of the torque stay 53 are opened as shown in FIG. 4 begins to be triggered. At this time, the protruding portion 51 moves along the guide groove 52 to the rear side along the circular arc trajectory having the edge 4A of the display portion 4 as the fulcrum O. As the projection 51 moves, the stopper 54 also moves rearward from the front end. Since the restoring force f in the direction of pulling the protruding portion 51 backward is applied to the protruding portion 51 by the elastic member 58, the protruding portion 51 is promoted to move along the guide groove 52. The guide receiving portion 57 moves from the upper end of the guide surface 56 to the lower side. When the guide receiving portion 57 comes into contact with the guide surface 56 from the x negative direction side, the display portion 4 can be prevented from moving in the tangential direction of the guide groove 52. As a result of the operation of each of these elements, the display unit 4 rotates around the fulcrum O while maintaining a state where there is no gap between the edge 4A and the upper surface 3.

  In the middle position as shown in FIG. 7, when the causing operation of the display unit 4 is stopped and the external force F disappears, the torque stay 53 can maintain the angle at this time by the frictional resistance of the hinge assembly 53C. Thereby, the display part 4 can hold | maintain an attitude | position with the arbitrary inclination angles between the state shown in FIG. 6 and the maximum angle position shown in FIG.

  Then, as shown in FIG. 8, when the display unit 4 is raised to the maximum angle position, the stopper portion 54 abuts against the stopper receiving portion 55, so that the protruding portion 51 interlocking with the stopper portion 54 no longer extends along the guide groove 52. It is restricted so that it cannot move backward. The guide receiving portion 57 moves to the lower end of the guide surface 56.

  When the display unit 4 shown in FIG. 8 is moved up to the maximum angular position and operated in the direction of tilting the display unit 4, the guide receiving unit 57 provided on the main body 22 is a guide surface provided on the display unit 4. It moves upward from the lower end of 56. Thereby, the display unit 4 rotates along a track defined by the shape of the guide surface 56. That is, in the case of the tilting operation, the display unit 4 rotates around the fulcrum O while maintaining a state in which there is no gap between the edge 4A and the upper surface unit 3 in the case of the tilting operation as in the above-described triggering operation.

  As described above, the terminal device 1 according to the present embodiment forms the guide groove 52 of the angle adjustment unit 5 in an arc shape centered on the edge 4A of the display unit 4, thereby causing the display unit 4 to move relative to the housing 2. The display unit 4 can be rotated around the edge 4A as the center of rotation. Thereby, it is possible to rotate the display unit 4 while maintaining a state in which there is no gap between the edge 4A of the display unit 4 and the upper surface unit 3. In this way, it is possible to prevent the appearance from becoming unsatisfactory due to a gap between the display unit 4 and the upper surface unit 3 regardless of the inclination angle of the display unit 4. As a result, the terminal device 1 can adjust the inclination angle of the display screen 41 provided in the display unit 4 without causing a gap between the display unit 4 and the housing 2. In addition, since it is not necessary to directly attach an element such as a hinge to the edge 4 </ b> A that is the rotation center of the display unit 4, for example, the display screen 41 is extended to the front end portion, and the degree of freedom of arrangement of the display screen 41 is increased. Can do.

  Further, the terminal device 1 according to the present embodiment moves the stopper receiving portion 55 of the angle adjusting portion 5 in contact with the stopper portion 54 when the display portion 4 is raised to the maximum inclination angle (see FIG. 8). By restricting the movement, the movement of the protruding portion 51 connected to the stopper portion 54 is also restricted, and the display portion 4 can be prevented from being raised beyond the maximum inclination angle.

  Further, in the terminal device 1 according to the present embodiment, the guide surface 56 of the angle adjustment unit 5 is provided on the back surface of the display unit 4 along the rotation direction of the display unit 4, and the guide receiving unit 57 is provided on the display unit 4. The main body 22 is provided to move the guide surface 56 while maintaining a contact state with the guide surface 56 according to the rotation. The guide surface 56 and the guide receiving portion 57 are urged by the elastic member 58 in a direction approaching each other, so that the contact state between the guide surface 56 and the guide receiving portion 57 is maintained. Thereby, it is possible to prevent the edge 4 </ b> A of the display unit 4 from separating from the upper surface part 3, particularly during the operation of tilting the display unit 4. Further, as in the case of the tilting operation, the display unit 4 is rotated around the fulcrum O while maintaining a state where there is no gap between the edge 4A of the display unit 4 and the upper surface unit 3. Can do. Therefore, regardless of the inclination angle of the display unit 4, it is possible to further reliably prevent a gap from being generated between the display unit 4 and the appearance from being deteriorated.

  Further, the terminal device 1 according to the present embodiment connects the elastic member 58 between the protruding portion 51 and the main body 22 so as to give the restoring force f that pulls the protruding portion 51 in the direction that causes the display unit 4. Further, it is possible to promote the movement of the protrusion 51 along the guide groove 52 during the causing operation of the display unit 4 by the restoring force f, and the causing operation can be performed more smoothly.

  The present embodiment has been described above with reference to specific examples. However, the present disclosure is not limited to these specific examples.
