The rotation hole 12c is formed with a diameter slightly larger than the diameter of the rotation support portion 11c. The bracket 12 is rotatably supported around the rotation support portion 11c of the shaft 11 through the rotation hole 12c of the rotation portion 12b. Washers 15 and 16 are provided on the rotation support portions 11c before and after the rotation portion 12b of the bracket 12, respectively. That is, a washer 15 is provided between the base portion 11a of the shaft 11 and the rotating portion 12b of the bracket 12, and between the rotating portion 12b of the bracket 12 and a disc spring 13 to be described later. A washer 16 is provided at the tip of the rotation support portion 11c that is the outside of the spring 13 (the side opposite to the washer 15). The through holes 15a and 16a of these washers 15 and 16 are formed in a shape slightly larger than the shape of the rotation support portion 11c, and the washers 15 and 16 are movable in the axial direction of the rotation support portion 11c. However, it is provided so that it cannot rotate. The distal end portion of the rotation support portion 11c protrudes from the washer 16, the protruding portion is caulked, and the bracket 12 is rotatably supported by the shaft 11.

The rotating means 6 is preferably provided with a friction member that generates friction by pressing the rotating portion 12b of the bracket 12 against the base portion 11a of the shaft 11 (actually pressing it through the washer 15). The friction member is not particularly limited, and is preferably a disc spring 13 or the like, for example. The disc spring 13 is provided, for example, between the rotating portion 12b of the bracket 12 and the washer 16 on the distal end side, and actually around the axis of the rotating support portion 11c between the washer 15 and the washer 16. It is preferable. As a result, the rotating portion 12b of the bracket 12 is pressed against the base portion 11a of the shaft 11, and friction is generated. The second housing 3 is rotated with respect to the first housing 2 to rise, and the rotation is stopped. At this time, the second housing 3 stops at a rising angle at an arbitrary position .

  Further, one of the first housing 2 and the second housing 3, for example, the second housing 3, and the other housing of the first housing 2 and the second housing 3, for example, It is preferable that a restricting portion that engages with the first housing 2 and restricts the rotation of the second housing 3 with respect to the first housing 2 is provided. The restricting portion is not particularly limited, and may be, for example, a convex portion 35 that protrudes downward near the end on the near side on the lower surface of the second housing 3. The convex portion 35 is in contact with the upper surface of the first housing 2 between the closed state and the closed state until immediately before the open state, and the rotation of the second housing 3 with respect to the first housing 2 is restricted. It is formed as follows.

  In addition, it is preferable that a rotation permission portion 25 is provided on the upper surface of the first housing 2. The rotation permission unit allows the first housing 2 and the second housing 3 to rotate when the first housing 2 and the second housing 3 are slid from each other to the opened state. When the second housing 3 with respect to the first housing 2 reaches a predetermined angle, for example, a rotation angle of 40 °, the rotation is stopped. For example, the rotation allowing portion 25 is formed in a concave shape on the upper surface of the first housing 2. That is, when the first housing 2 and the second housing 3 slide to each other and are in the slide open state, the concave rotation allowing portion 25 is provided at a position where the convex portion 35 of the second housing 3 comes into contact, It is preferable that the second housing 3 can be rotated. Further, the rotation allowing portion 25 has a stopper portion (not shown) that stops the rotation when the second housing 3 has a rotation angle of 40 ° with respect to the first housing 2. Is preferred. As a result, when the first housing 2 and the second housing 3 slide from each other to the open state, the second housing 3 is rotated about the shaft 11 with respect to the first housing 2. When the rotation angle reaches 40 °, the rotation is stopped and the opening rotation state is established.

  Next, the operation of the mobile device according to the present invention will be described.

  In a normal state in which the portable device 1 is not used, the first housing 2 and the second housing 3 are in a closed state where they overlap each other. At this time, the urging force of the spiral spring 92 urges the free end of the swivel arm 91 to the far side (front side) of the slider member 8, and the slide member 73 comes into contact with the closed end of the slide recess 81. Since the member 7 and the slider member 8 are locked, the first casing 2 and the second casing 3 are held in a closed state where they overlap each other. In order to maintain this closed state more reliably, a lock mechanism may be provided.

When using the portable device 1, for example, a force is applied to the second housing 3 so that the second housing 3 slides with respect to the first housing 2 to be in an open state. That is, the second casing 3 is slid by applying force to the first casing 2 in the opening direction. Then, the turning arm 91 rotates around the turning shaft 95 . At this time, the spiral spring 92 is stretched in the circumferential direction against the urging force by receiving a load due to the sliding force.

When the neutral state is reached (see FIG. 8), when the biasing force applied to the free end portion of the swing arm 91 by the spiral spring 92 acts in the direction of the swing shaft 95 , the slide member 73 has no biasing force in the sliding direction. . That is, the sliding force becomes zero. When the neutral state is passed, the position of the pivot fulcrum (center of the pivot shaft 95 ) of the pivot arm 91 and the free end thereof are relatively reversed, and the pivot arm 91 is rotated by the spiral spring 92 around the pivot shaft 95. Since the free end of the second casing 3 is biased in the direction away from the turning shaft 95 , the second casing 3 automatically slides in the opening direction with respect to the first casing 2 to be in the opened state. In addition, it is desirable to provide a slide restricting portion in the first casing 2 and the second casing 3 so that the sliding of the first casing 2 and the second casing 3 stops when the opened state is reached. .

  Even in this open state, the free end of the swivel arm 91 is biased toward the front side of the slider member 8 by the biasing force of the spiral spring 92, so that the first housing 2 and the second housing 3 are in the open state. Will be held. As a result, the keyboard provided on the upper surface of the first housing 2 is exposed, and the keyboard can be operated. In order to maintain this open state more reliably, a lock mechanism may be provided. Therefore, the slide operation can be performed semi-automatically when sliding from the closed state to the open state.

At this time, when it is difficult to see the display 31 of the second housing 3, the second housing 3 is rotated with respect to the first housing 2. That is, in the opened state, the convex portion 35 of the second housing 3 is positioned on the rotation allowing portion 25, so that the second housing 3 can rotate with respect to the first housing 2. The second housing 3 can be rotated with respect to the first housing 2 around the shaft 11 until the rotation angle becomes 40 °. If the rotation is stopped in the middle of the rotation, the rotating portion 12b of the bracket 12 is pressed against the base portion 11a of the shaft 11 by the disc spring 13, and friction is generated. 3 is held at the position where the rotation is stopped. As a result, since the rising angle of the display 31 can be changed to an arbitrary angle, a keyboard operation or the like can be performed in an easy-to-see state on the image displayed on the display 31, so that the usability is improved.

To return to the closed state after use, the second housing 3 is rotated with respect to the first housing 2 and returned to the horizontal state , and then the second housing 3 is opened with respect to the first housing 2. When sliding from the closed state to the closed state, the spiral spring 92 extends in the circumferential direction against the biasing force. When the neutral state is passed and the position of the pivot point of the swivel arm 91 and the free end thereof are relatively reversed, the second housing 3 and the first housing 3 are biased by the urging force of the spiral spring 92 around the swivel shaft 95 . The housing 2 is biased in the closing direction. As a result, the second housing 3 automatically slides in the closing direction with respect to the first housing 2, and the slide member 73 comes into contact with the closed end portion of the slide recess 81 and enters the closed state. Therefore, the slide operation can be performed semi-automatically when sliding from the open state to the closed state.

  Therefore, the portable device 1 according to the present invention can be opened / closed semi-automatically and the angle of the second housing 3 with respect to the first housing 2 can be changed.

  Further, since the slide operation is performed semi-automatically using the swing arm 91, the spiral spring 92, the disc spring 13 and the like, and the rotation operation is performed, the number of parts can be reduced, and the cost can be reduced and the size can be reduced. . Various sliding operations can be set by changing the elastic characteristics of the spiral spring 92 and the position and length of the swivel arm 91. For example, by increasing the urging force of the urging means 9 in the closed state and the open state, the force for maintaining the closed state and the open state can be increased, and the closed state and the open state can be reliably maintained. Will be able to.

  As described above, the portable device according to the present invention includes the semi-auto means and the rotating means, so that the second housing automatically opens and closes from the predetermined position with respect to the first housing. The first housing and the second housing can be automatically slid in a semi-automatic manner, and the second housing rotates with respect to the first housing in the open state. Since the angle of the two housings can be changed, the usability is improved, so that it is particularly suitable for use in a portable terminal.
