FIG. 4B is a partially enlarged view showing the relationship between the cam and the cam, and FIG. 5B is a sectional view taken along line BB in FIG. In FIG. 2, a rotation assist compression coil spring 330, a cam 331, and a roller 332 are assembled to the operation side member 320, and the display side member 310 is linked to the operation side member 320 via a vertical axis 333 and a horizontal axis 334. Although it operates, in FIG. 5 and FIG. 6, the shape of the display side member is simplified, and the rotation mechanism 300 will be described. That is, in FIG. 5 and FIG. 6, the operation side member is denoted by reference numeral 10, the display side member is denoted by reference numeral 20, and the rotation assist compression coil spring is denoted by reference numeral 30.

As shown in FIG. 5, the rotation mechanism 300 includes a plate-like operation side member 10 (operation side member 320) provided in the operation side main body 200 and a plate-like display side member 20 provided in the display side main body 100. (Display-side member 310). The operation side member 10 has a longitudinal groove (first guide groove) 12 extending in the longitudinal direction of the operation side housing 201, an elastic member groove 13 extending substantially parallel to the longitudinal groove 12, and toward the longitudinal groove 12. A lateral groove (second guide groove) 11 that is convexly curved is formed, and a spring locking protrusion 14 is formed at the upper end of the elastic member groove 13. On the other hand, a hole 21 for fixing the horizontal axis 40 and a hole 22 for fixing the vertical axis 50 are formed in the display side member 20. If the horizontal axis 40 and the vertical axis 50 are screw rods, and the holes 21 and 22 are screw holes, the horizontal axis 40 and the vertical axis 50 are screwed into the holes 21 and 22 so that the horizontal axis 40 and the vertical axis 50 are displayed. It can be fixed to the member 20.

The horizontal shaft 40 has a head portion and a shaft portion. After the shaft portion is inserted into the lateral groove 11 from the back surface side (back surface side of the mobile phone) of the operation side member 10, the shaft portion is inserted into the surface of the operation side member 10. The display side member 20 is attached to the display side member 20 by being fixed to the hole 21 of the display side member 20 arranged on the side. The head of the horizontal shaft 40 has a size that does not pass through the horizontal groove 11. On the other hand, the vertical axis 50 similarly has a head portion and a shaft portion. A roller 51 is fitted into the shaft portion, and the shaft portion is inserted into a hole 54 provided in the cam 52, and then a longitudinal groove is formed. 12, and the shaft portion is fixed to the hole 22 of the display side member 20, and is attached to the display side member 20. The cam 52 has a shape larger than the width of the longitudinal groove 12, and a hole 54 provided in the center thereof has a substantially rectangular shape. A roller 51 is disposed in the hole 54, and The vertical axis 50 can be moved in the longitudinal direction of the longitudinal groove 12 by the rotation.

A protrusion 55 is disposed at the peripheral portion of the hole 54 at the end of the cam 52 far from the lateral groove 11. In addition, two concave portions 56a and 56b are formed on the head of the vertical axis 50, and as shown in FIG. 6A, when the rotation angle is 0 °, the projection 55 fits into the concave portion 56a. When the display side member 20 is in the middle of rotation as shown in FIG. 6B, the projection 55 is detached from the recess 56a, and when the rotation angle is 90 ° as shown in FIG. 6C. The protrusion 55 is fitted into the recess 56b. The protrusion 55 is inserted into and removed from the recesses 56 a and 56 b when the vertical axis 50 moves in the hole 54 by the rotation of the roller 51.

The cam 52 is formed with an extending portion 53 extending from the lower end portion thereof toward the elastic member groove 13. At the tip of the extended portion 53, a spring locking projection 57 is formed. As shown in FIG. 6, after the vertical axis 50 is assembled to the display side member 20, the spring locking projection 57 of the cam 52 and the spring locking projection 14 of the operation side member 10 are The compression coil spring 30 for assisting rotation is locked. The compression coil spring 30 urges the vertical axis 50 toward the lateral groove 11 via the cam 52. At this time, as shown in FIG. 6A, when the rotation angle of the display side member 20 is 0 °, the coil spring 30 is in the most extended state, and the coil spring 30 is shortened as the display side member 20 rotates. As the coil spring 30 becomes the shortest and the display-side member 20 rotates further in the middle, the coil spring 30 continues to expand until the rotation angle reaches 90 °.

As shown in FIGS. 7A and 7B, the compression coil spring 30 is locked by inserting the spring locking protrusions 14 and 57 into the coil spring 30. Since the spring locking projections 14 and 57 are disposed at both ends in the longitudinal direction of the elastic member groove 13, the coil spring 30 is positioned in the elastic member groove 13. For this reason, in order to provide the coil spring 30, it is not necessary to prepare a space in the thickness direction corresponding to the diameter of the coil spring 30. If only a portion of the coil spring 30 protruding from the elastic member groove 13 is provided, a spatial margin is provided. Good.

Next, the operation of the mobile phone according to this embodiment configured as described above will be described. As shown in FIGS. 1 to 3, when the display-side main body 100 is pushed upward, the slide rail 110 slides upward against the display-side member 310 against the biasing force of the slide assist spring 120, and the stroke After passing the intermediate point, the slide assist spring 120 receives an urging force to slide further upward. Therefore, the display-side main body 100 maintains the closed state in FIG. 1A and the open state in FIG. 1B by the urging force of the spring 120.

When the display-side main body 100 is rotated clockwise from the state shown in FIG. 1B, the display-side member is viewed from the back side as shown in FIGS. 6A to 6C. 20 rotates counterclockwise when viewed from the back side against the urging force of the rotation assist compression coil spring 30. As shown in FIG. 6B, the coil spring 30 becomes the shortest during this rotation, and then further rotated, the coil spring 30 expands as shown in FIG. 6C. At this time, as shown in FIG. 6A, when the horizontal axis 40 is positioned at the left end of the horizontal groove 11 shown in the figure, the display-side main body 100 is a normal telephone as shown in FIG. When the horizontal shaft 40 is positioned at the right end of the horizontal groove 11 as shown in FIG. 6C, the display-side main body 100 is shown in FIG. As shown in Fig. 4, the horizontal state is optimal for watching TV or browsing the web. The display-side main body 100 maintains the vertically long state and the horizontally long state unless forcedly rotated by the biasing force of the compression coil spring 30.

In the present embodiment, an elastic member that applies a biasing force to the display-side main body 100 and the operation-side main body 200 is disposed in the elastic member groove 13, so that the thickness of the mobile phone is increased to provide the elastic member. Can be prevented. Further, by using a coil spring as the elastic member, the space in which the spring moves can be made as small as possible for the operation of the rotating mechanism, and an increase in the size of the mobile phone can be prevented. In addition, since the coil spring 30 is disposed in the groove 13 provided in the vicinity of the vertical groove 12 along which the vertical axis 50 moves, the space required for connecting the vertical axis 50 and the coil spring 30 can be reduced.

Thus, in the present embodiment, the mobile phone that can switch between the vertically long state and the horizontally long state can be reduced in size and thickness.

Further, with the rotation of the display-side main body 100, at one rotation angle (0 °), the concave portion 56a provided on the vertical axis 50 is fitted into the protrusion 55 provided on the cam 52, and the other rotation angle is set. Since the concave portion 56b provided on the vertical axis 50 is engaged with the protrusion 55 provided on the cam 52 at (90 °), when the rotation angle is separated from the vertically long state of 0 °, the rotation angle is 90 °. The operator is given a click feeling when leaving the landscape state. Therefore, the operator can operate with peace of mind when performing operations in the vertically long state and the horizontally long state.
