  By the way, in the slide mechanism composed of the slide member (3) and the pair of guide rails (4) and (4), the second housing (8) can smoothly slide with respect to the first housing (1). In order to achieve this, a minimum amount of play is required between the slide member (3) and the guide rails (4) and (4).

  However, as shown in FIG. 8, the first casing (7) and the second casing (8) each have a laterally long outer shape, and the vertical dimension along the sliding direction is the horizontal direction perpendicular to the sliding direction. In the slide type electronic device formed smaller than the size of the guide rail, the length of the guide rails (4) and (4) constituting the slide mechanism cannot be designed sufficiently large due to the limitation of the external dimensions. If the necessary play is provided between the slide member (3) and the guide rails (4) and (4), the second housing (8) will be rattled in the direction crossing the slide direction. There was a problem that obstructed the sliding movement.

  Further, since the slide member (3) is made of sheet metal, when an impact is applied to the slide mechanism due to dropping or the like, stress concentrates on the engaging portion (31) of the slide member (3) with respect to the guide rail (4), In some cases, the engaging portion (31) of the slide member (3) is plastically deformed, and as a result, there is a problem that the backlash when the second housing (8) is slid further increases.

  Accordingly, an object of the present invention is to provide a sliding electronic device that can maintain a smooth sliding operation of the second housing relative to the first housing even when an impact is applied during use. .

In the sliding electronic device according to the present invention, the second casing (2) is slidably engaged with the first casing (1), and the first casing (1) and the second casing (2) are engaged. Between the pair of left and right guide rails (4) and (4) extending along the sliding direction of the second housing (2) and the guide rails (4) and (4). A slide mechanism including a metal slide member (3) is provided.
One of the first casing (1) and the second casing (2) has a second casing (2) on both sides of the pair of guide rails (4) and (4 ). A pair of left and right guide grooves (6) and (6) extending in the sliding direction are recessed, and the other housing is slidably engaged with the pair of guide grooves (6) and (6), respectively. A pair of sliding pieces (5) and (5) made of resin are provided.
Here, one guide rail (4) and one guide groove (6) are disposed on one side of the left and right sides of the one casing, and the other guide rail ( 4) and the other guide groove (6) are arranged.

In a specific configuration, each of the first casing (1) and the second casing (2) is formed such that a vertical dimension parallel to the sliding direction is smaller than a horizontal dimension perpendicular to the sliding direction. Yes.

  In the slide type electronic apparatus of the present invention, a first slide mechanism composed of a pair of guide rails (4), (4) and a slide member (3) similar to the conventional one is provided, and on both sides thereof. Since the second slide mechanism comprising the pair of guide grooves (6) and (6) and the pair of sliding pieces (5) and (5) is provided, the first casing (1) and the second casing are provided. Even when the body (2) has a laterally long outer shape in a direction perpendicular to the sliding direction, the second casing (2) relative to the first casing (1) is guided by the guides of the two sliding mechanisms. The backlash at the time of sliding is suppressed.

Further, it is assumed that an impact is applied to both slide mechanisms by dropping or the like, and stress concentrates on the metal slide member (3) constituting the first slide mechanism, so that a part of the slide member (3) is plastically deformed. However, since the sliding piece (5) constituting the second sliding mechanism is made of resin, the sliding piece (5) is elastically deformed by the action of an external force within a certain limit, and the sliding piece (5) And the guide groove (6) are maintained at an appropriate size.
Therefore, rattling during the sliding of the second casing (2) relative to the first casing (1) is suppressed by the guide by the second sliding mechanism.

  According to the slide type electronic apparatus according to the present invention, even if an impact is applied during use, the smooth sliding operation of the second casing relative to the first casing can be maintained.

Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.
As shown in FIGS. 1 and 2, the sliding electronic device according to the present invention includes a first housing (1) having a numeric keypad mainly disposed on the surface and a second housing having a function key mainly disposed on the surface. The body (2) is configured to allow the second housing (2) to slide relative to the first housing (1).

  As shown in FIG. 1, the first casing (1) and the second casing (2) are each in the lateral direction in which the vertical dimension B along the sliding direction of the second casing (2) is perpendicular to the sliding direction. It is formed smaller than the dimension A.

As shown in FIG. 3, a pair of left and right guide rails (4) and (4) extending along the sliding direction of the second housing (2) are arranged on the inner surface of the second housing (2). (4) In (4), a sheet metal slide member (3) is slidably engaged with the engaging portions (31), (31) on both sides, and the slide member (3) is in the first housing. It is connected to the inner surface of (1).

As the synthetic resin that is the material of the sliding piece (5), a material that exhibits greater elasticity (impact resistance) than the metal that is the material of the sliding member (3) is employed.

  As shown in FIGS. 6 and 7, each sliding piece (5) has a pair of convex portions (51) arranged in the sliding direction of the second casing (2) on the surface facing the second casing (2). ) (51) is formed to reduce the frictional resistance in the process of sliding the sliding piece (5) along the guide groove (6) of the second casing (2).

  According to the slide type electronic device of the present invention, a pair of guide grooves (6) and (6) and a pair of slide pieces (5) and (5) are formed on both sides of the first slide mechanism similar to the conventional one. Since the second slide mechanism is provided, rattling when the second housing (2) slides relative to the first housing (1) is suppressed by the guides of the two slide mechanisms.

Moreover, an impact is applied to both slide mechanisms by dropping or the like, and stress concentrates on the engagement portion (31) of the metal slide member (3) constituting the first slide mechanism, so that the engagement portion (31) Even if plastically deformed, the sliding piece (5) constituting the second sliding mechanism is made of synthetic resin. Therefore, the sliding piece (5) is elastically deformed by the action of an external force within a certain limit, and the sliding piece (5) is slid. The play between the moving piece (5) and the guide groove (6) is maintained at an appropriate size.
