The convex portion 11 engages with the two rails 13 and slides on the concave portion 12. Further, a rail stopper 14 is provided at the end of the recess 12. Further, a slide assist member (biasing means) 15 is accommodated in the recess 16 between the first casing 1 and the second casing 2 between the pair of left and right convex portions 11 and concave portion 12. Yes.

  That is, as shown in an enlarged manner in FIG. 4 and subsequent figures, the first housing 1 is composed of a lower case 1a and an upper case 1b, and a pair of left and right convex portions 11 are integrally formed on the upper surface of the upper case 1b. ing. As shown in FIG. 6, the convex portion 11 has a square cross section and a certain length, and is located closer to the left and right side portions of the upper case 1b. In the illustrated example, a longitudinal through hole 11 a is formed in the convex portion 11, and a side groove 11 b is formed in the inner side surface of the convex portion 11 along the longitudinal direction.

  The second housing 2 is also composed of a lower case 2a and an upper case 2b, and a pair of left and right recesses 12 are integrally formed on the lower surface of the lower case 2a. As shown in FIG. 7, the concave portion 12 is a groove having a square cross section and is sufficiently longer than the convex portion 11, and is located closer to the left and right side portions of the lower case 2b. In the illustrated example, a side groove 12b is formed on the inner side surface of the recess 12 along the longitudinal direction.

  The convex portion 11 is inserted into the concave portion 12 described above, the two rails 13 are inserted into the concave portion 12 from the insertion hole at one end portion, the first rail 131 is inserted into the through hole 11a of the convex portion 11, and the tip thereof Is inserted to the other end of the recess 12. Further, the second rail 132 is inserted between the side surface groove 11 b of the convex portion 11 and the side surface groove 12 b of the concave portion 12, and the tip thereof is similarly inserted to the other end portion of the concave portion 12. Thereafter, the rail stopper 14 is attached to the outer end portion from the insertion hole at one end portion of the concave portion 12 by concave and convex fitting.

  Further, a recess 16 extending between the left and right recesses 12 is integrally formed on the lower surface of the lower case 2 a of the second housing 2. A slide assist member (biasing means) 15 is accommodated in the recess 16. That is, the slide assist member 15 that is an urging means includes a cylinder 15a, a pair of rods 15b that are partly accommodated in the cylinder 15a and projecting in opposite directions, and a pair of rods 15b in the cylinder 15a. It comprises a pair of compression coil springs (not shown) that are urged in the protruding direction. By the biasing of the pair of compression coil springs, the slide assist member 15 can be expanded and contracted by a pair of rods 15b protruding in directions opposite to each other with respect to the cylinder 15a.

  The pin 15c provided at the protruding end of one rod 15b of the slide assist member 15 is inserted into the hole 16c formed at one side of the recess 16, and the pin 15c at the protruding end of the other rod 15b is inserted. The first casing 1 is inserted into a hole 1c formed on the other side of the upper case 1b. Thus, the slide assist member 15 is accommodated in the recess 16 on the lower surface of the lower case 2a of the second housing 2.

  In this way, the slide assist member 15 is accommodated in the recess 16 on the lower surface of the lower case 2a of the second casing 2, and the protrusion 11 is inserted into the left and right recesses 12 of the recess 16 so that the first casing 1 is After the assembly, the two rails 13 are inserted into the recess 12 from the insertion hole at one end. Then, a rail stopper 14 is attached to the outer end portion from the insertion hole at one end portion of the concave portion 12 by concave-convex fitting to finish the assembly.

As shown in FIG. 1B, in the state where the second casing 2 is slid to expose the numeric key operation unit 3 of the first casing 1, the two casings 1 and 2 is held in an oblique state in a direction intersecting with the above.

  The sliding operation amount of both the housings 1 and 2 is limited by the protrusion 11 of the first housing 1 abutting against the end of the recess 12 of the second housing 2. Therefore, the convex portion 11 and the concave portion 12 also function as a stopper (fixing member) that limits the amount of movement during the sliding operation of both the housings 1 and 2.

Next, the operation will be described.
First, as shown in FIG. 1A, in a state where the second housing 2 is overlapped on the first housing 1, the second housing 2 is slid by hand to the upper side in the drawing. At this time, since the slide assist member 15 is held in an oblique state with respect to both the casings 1 and 2, the second casing 2 is slid by a force that overcomes the urging force of the compression coil spring. Thereby, along the two rails 13 in the pair of left and right recesses 12 of the second housing 2, the pair of left and right projections 11 of the first housing 1 is formed with the through holes 11 a and the side grooves 11 b and 12 b. Each slides while engaging.

  In the process, the slide assist member 15 changes to an oblique state in a direction intersecting the above through a direction orthogonal to both housings 1 and 2, and is shown in FIG. 1 (b) by the urging force of the compression coil spring. As described above, the second casing 2 is automatically slid to change to a state in which the numeric keypad operation unit 3 of the first casing 1 is exposed. At this time, the sliding motion amount is regulated by the protrusion 11 hitting one end of the recess 12. Therefore, in addition to the cross key and function key operation unit 4 of the second housing 2 having the display screen 5, the numeric keypad operation unit 3 of the first housing 1 exposed on the lower side of the second housing 2 in the drawing. Is also ready for use.

  On the other hand, the second casing 2 is slid by hand to the lower side in the figure from the state in which the numeric keypad 3 shown in FIG. 1B is exposed. Also at this time, since the slide assist member 15 is held in an oblique state with respect to both the housings 1 and 2, the second housing 2 is slid by a force that overcomes the urging force of the compression coil spring. As a result, the pair of left and right projections 11 of the first housing 1 are formed along the through holes 11a and the two rails 13 in the pair of left and right recesses 12 of the second housing 2 in the same manner as described above. The slide movements are performed while engaging the side grooves 11b and 12b.

  Therefore, in the process, as described above, the slide assist member 15 changes to an oblique state in a direction crossing the above through the direction orthogonal to both housings 1 and 2, and by the biasing force of the compression coil spring, As shown in FIG. 1A, the second casing 2 is automatically slid to cover the numeric keypad operation unit 3 and return to a state in which the first casing 1 overlaps and is aligned. Also at this time, the sliding motion amount is regulated by the protrusion 11 hitting the other end of the recess 12.

  As described above, according to the embodiment, the sliding mechanism is capable of sliding the first casing 1 and the second casing 2 of the mobile terminal, and is integrally formed with the second casing 2. A pair of left and right convex portions 11 formed integrally with the first housing 1 along two cylindrical rails 13 (first rail 131 and second rail 132) inserted into the pair of left and right concave portions 12 are provided. Since it slides and does not require a conventional assist mechanism, the shape of the portable terminal can be reduced.

  And the 1st housing | casing 1 and the 2nd housing | casing 2 can be slidably engaged by the above slide mechanism, without screwing. Moreover, the assembly is easy. Therefore, the number of assembly steps can be reduced and the cost can be reduced.

In the above embodiment, the portable terminal is used. However, the present invention is not limited to this and may be a PDA or other portable device.
In the embodiment, the first casing is provided with a convex portion and the second casing is provided with a concave portion. Conversely, the first casing is provided with a concave portion, and the second casing is provided with a concave portion. A convex portion may be provided.
Furthermore, the shape of a convex part or a recessed part is arbitrary, and it is needless to say that other detailed structures can be appropriately changed.
