  What is indicated by an instruction symbol 4 is a slide member attached to the lower surface of the second housing 2, and guide portions 4 a and 4 a formed in the longitudinal direction of both side ends thereof are provided as guide grooves 3 a of the base member 3. , 3a, the first casing 1 can be slid in the linear longitudinal direction. It is also conceivable that the guide groove is provided toward the slide member 4 and the guide portion is provided toward the base member 3. Furthermore, it is conceivable to attach the base member 3 to the second housing 2 side and attach it to the slide member 4 and the first housing 1 side.

  What is indicated by an instruction symbol 5 is a swing arm. The swing arm 5 is installed between the base member 3 and the slide member 4 and can be horizontally rotated by a mounting pin 6 with respect to the base member 3. It is pivotally supported. A coil spring 7 made of a tension coil spring is stretched between one end of the swing arm 5 beyond the pivot point and the end of the slide member 4, and the swing arm 5 is always rotated in one direction. It is energized. The mounting pin 6 may be configured integrally with the swing arm 5.

  The number of coil springs is one in the drawing, but a plurality of coil springs may be used. The coil spring 7 may be replaced with other elastic means for generating a tensile force or a compression coil spring for generating a compressive force in the opposite direction.

  The base member 3 is provided with a leaf spring piece 3b cut and raised from the surface portion, and a guide piece 3c. The leaf spring piece 3b and the guide piece 3c are provided with a first guide groove 4b provided on the back side of the slide member 4. It fits in the second guide groove 4c. The leaf spring piece 3b is a stopper at the fully opened position of the second housing 2 with respect to the first housing 1, and the leaf spring is formed when the slide member 4 is assembled into the base member 3, that is, the slide. When the guide portion 4a of the member 4 is fitted into the guide groove 3a of the base member 3, the leaf spring piece 3b can be fitted over the first stopper portion 8a. Is for abutting against the first stopper portion 8a and preventing both from being detached. Further, as will be described later, the guide piece 3c also serves as a stopper in the fully closed position of the second casing with respect to the first casing 1.

  A cam flower 5b is provided on the end of the swing arm 5 beyond the shaft fulcrum, that is, on the tail side located on the opposite side of the head 5a on the side where the coil spring 7 is attached. The cam flower 5b is in contact with a cam portion 9 provided in the longitudinal direction of the slide member 4, and the cam portion 9 has a start end dropping portion 9a and a terminal end dropping portion 9a at which the cam floor 5b of the swing arm 5 falls at the start end portion and the terminal end portion. A drop portion 9b is provided.

  Next, the operation will be described. In the closed state in which the first casing 1 and the second casing 2 overlap each other, the swing arm 5 is unidirectionally moved by the coil spring 7 as shown in FIGS. In other words, the second casing 2 is pulled in the opening direction away from the first casing 1, so that the second casing 2 is urged to rotate counterclockwise about the mounting pin 6. However, the cam flower 5b has fallen into the start-end drop part 9a of the cam part 9, and the slide member 4 is locked by this cam flower 5b. Accordingly, the second casing 2 is slidably biased away from the first casing 1, but is locked in this state, and the first casing 1 and the second casing 2 are The closed state where they overlap each other is maintained.

  Now, when the second casing 2 is pushed against the first casing 1 (here, the first casing 1 and the second casing may be pulled. Both operations are performed. The cam follower 5b of the swing arm 5 escapes from the start-end drop portion 9a of the cam portion 9, releases the locked state with respect to the slide member, and the closed lock state is released. Then, since there is no thing which locks the swing arm 5 to the slide member 4, the slide member 4 is automatically slid with respect to the base member 3 by being pulled in one direction by the tensile force of the coil spring 7, and 2 is slid in the opening direction with respect to the first housing 1. As a result, the second housing 2 is automatically opened with respect to the first housing 1 as shown in FIGS. 2 and 9B.

  When the second housing slides to the required position with respect to the first housing, the leaf spring piece 3b is moved to the first stopper of the slide member 4 as shown in FIGS. 3, 7 and 9C. When the cam follower 5b of the swing arm 5 falls into the terminal drop portion 9a of the cam portion 9, the second casing 2 is opened relative to the first casing 1 by being stopped by contacting the portion 8a. Locked in position.

  In this way, the keyboard portion 1a provided on the upper surface of the first housing is exposed, so that calls and keyboard operations can be performed.

  From this state, the swing arm can be moved by pulling the second housing 2 in the original direction, pushing the first housing 1 against the second housing 2, or simultaneously performing both operations. 5 of the cam flower 5b escapes from the terminal drop 9b and is released from the open lock state. Then, the cam follower 5b comes into contact with the flat portion 9c of the cam portion 9 and can slide while rotating slightly in the clockwise direction, and the slide member 4 can slide while stretching it against the pulling force of the coil spring 7. Therefore, the second housing 2 is slid with respect to the first housing 1 and closed. 1, 7, and 9 (a), the guide piece 3 c comes into contact with the second stopper portion 8 b of the slide member 4, and the cam follower 5 b of the swing arm 5 is connected to the cam portion 9. When the swing arm 5 falls into the start-end drop portion 9a and the swing arm 5 is slightly reversed from the position indicated by the imaginary line in FIG. 1 to the position indicated by the solid line and the slide member 4 is locked by the cam follower 5b, The housing 2 is locked to the first housing 1 in the closed position.

  As described above, the second casing 2 is locked with respect to the first casing 1 in the closed position. When the locked state is released, the second casing 2 is automatically slid and opened to a predetermined position. It will be locked again in position.

  As described above, in the present invention, in the mobile terminal, in particular, the first casing that constitutes the transmitter of the mobile phone and the second casing that constitutes the receiver are slidably connected to each other and closed. It can be used as a slide mechanism that automatically slides in a linear direction from the state and opens.
