  Of the above-described conventional electronic apparatus stand holding structure, the former has a problem that the number of parts increases because a base member is required in addition to the stand member. In addition, the latter of the above-described conventional electronic apparatus stand holding structures has a structure in which the entire stand member is elastically deformed to support the stand member on the bearing portion, so that the strength of the stand member can be increased. Can not. Further, since the stand member is erected, the elastic portion of the stand member is engaged with the click stop portion while being elastically deformed, and therefore the strength of the elastic portion cannot be increased. For this reason, when an excessive external force is applied to the housing, there is a problem that the stand member is damaged or the stand member is dropped from the bearing portion and the housing is damaged.

  The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to reduce the number of parts and prevent damage to the stand member and the casing.

The invention according to claim 2 is the invention according to claim 1, wherein the shaft support portion is provided integrally with the one rotation restricting portion, and the one rotation restricting portion extends in the axial direction of the stand member. It is provided to do.

According to the first aspect of the present invention, since only a stand member is required as a component, the number of components is reduced. Further, since the elastic deformation of the stand member and the housing-side holding member is not used to hold the stand member in the raised state, the rigidity of the stand member and the rotation restricting portion can be increased and the strength can be increased. Even if an excessive external force is applied to the electronic device, it is possible to prevent the stand member from falling off the rotation restricting portion and the stand member and the casing from being damaged.

According to the invention of claim 2, since the rigidity of the rotation restricting portion can be increased and the strength can be increased, the stand member can be more reliably prevented from falling off from the rotation restricting portion and the stand member and the casing being damaged. can do.

As shown in FIG. 5, the distance L2 between the end restriction surface 19b and the end restriction portion 18 is formed to be larger than the width L1 of the stand member 7 by a length l, and is freely rotatable on the shaft support portion 15. The supported stand member 7 is configured to be movable in the arrow AB direction by a length l between the end limit restricting surface 19b and the end limit restricting portion 18. Further, the distance L3 between the end limit restricting portions 18 and 19 is formed to be slightly larger than the width L1 of the stand member 7.

  Reference numeral 20 denotes an elastic engagement piece having a claw formed at the tip, which is the bottom of the lower case 2 and is erected integrally at the center in the direction of arrow AB and on the end in the direction of arrow C. When the stand member 7 rotatably supported by the shaft support portion 15 is laid down as shown in FIG. 4, the stand member 7 is engaged with the engagement shaft 27 of the stand member 7 to bring the stand member 7 into the lower case 2. Maintains close contact with the bottom. Reference numerals 21 and 21 denote rubber feet, which are provided at both ends in the direction of arrows AB at the ends in the direction of arrow C at the bottom of the lower case 2.

  In FIG. 2, the stand member 7 has leg portions 25A and 25B that are spaced apart from each other and formed in a flat, substantially rectangular parallelepiped shape, and a cross section that connects the base ends of the leg portions 25A and 25B is formed in a substantially circular shape. The pivot 26 is integrally formed with an engagement shaft 27 and a stay 28 that connect the swinging ends of the legs 25A and 25B. Concave portions 25a and 25b formed in a rectangular shape are provided at portions of the ends of the both leg portions 25A and 25B facing each other at the pivot 26 side. These recesses 25a and 25b allow the stand member 7 to be moved in a state where the engaging shaft 27 of the stand member 7 rotatably supported by the shaft support 15 is separated from the bottom of the lower case 2 as shown in FIG. When positioned at the end in the direction of arrow A, one recess 25 b is fitted into one bearing member 12. When the stand member 7 is moved in the direction of arrow B, the other recess 25a is fitted into the other bearing member 11 as shown in FIG. 13, and the recess 25a engages with the rotation restricting portion 11a of the bearing member 11. At the same time, one leg portion 25B engages with the rotation restricting surface 19c of the end limit restricting portion 19.

  Next, the case where the electronic device is used on a table in the electronic device stand holding structure having such a configuration will be described. In advance, the pivot shaft 26 of the stand member 7 is rotatably supported by the shaft support portion 15 of the lower case 2, and the engagement shaft 27 engages with the claw of the elastic engagement piece 20 as shown in FIG. Is in close contact with the bottom of the lower case 2. By elastically deforming the elastic engagement piece 20 from this state, the engagement between the engagement shaft 27 and the claw of the elastic engagement piece 20 is released, and the stand member 7 is rotated in the clockwise direction in FIG. And the engaging shaft 27 on the swinging end side is separated from the bottom of the lower case 2.

  At this time, the movement of the both leg portions 25A, 25B of the stand member 7 in the arrow AB direction is restricted by the end limit restricting portions 18, 19 as shown in FIG. Further, as shown in FIG. 11, the convex portion 16A (16B) provided at the bottom of the lower case 2 presses the leg portion 25A (25B) of the stand member 7, so that the convex portion 16A (16B) and the stand member 7 are in contact with each other. The sliding resistance increases between the two. For this reason, since braking is applied when the stand member 7 is rotated, the operability is improved and the usability is improved.

  As shown in FIG. 11, the leg portion 25 </ b> A of the stand member 7 is engaged with the rotation restricting portion 10 a of the ridge 10, thereby restricting the rotation of the stand member 7 in the clockwise direction in the drawing. At the same time, the leg portion 25A of the stand member 7 faces the concave portion 19a of the end limit restricting portion 19 as shown in FIG. 12, and the stand member 7 can be moved in the arrow B direction. The stand member 7 is moved in the arrow B direction as shown in FIG. 13, and the leg portion 25B is engaged with the end restriction surface 19b of the end restriction portion 19 as shown in FIG. At this time, since the convex portion 16A (16B) press-contacting the leg portion 25A (25B) of the stand member 7 increases the sliding resistance between the convex portion 16A (16B) and the stand member 7, the stand member Since braking is applied when moving 7, the operability is improved and the usability is improved.

  At this time, the recess 25a of the leg portion 25A is fitted into the other bearing member 11 as shown in FIG. 13, and the recess 25a engages with the rotation restricting portion 11a of the bearing member 11, and the one leg portion. 25B engages with the rotation restricting surface 19c of the end restricting portion 19. Therefore, the rotation of the stand member 7 in the counterclockwise direction in FIG. 6 is restricted by the rotation restriction portion 11a and the rotation restriction surface 19c. In other words, the stand member 7 is sandwiched between the rotation restricting portion 11a and the rotation restricting surface 19c and the rotation restricting portion 10b of the above-described protrusion 10, and the rotation in the clockwise direction and the counterclockwise direction is restricted. Is done. Since this rotation restriction does not use elastic deformation as in the prior art, the rigidity of the rotation restriction portion 11a and the rotation restriction surface 19c and the rotation restriction portion 10b of the above-described convex body 10 is increased. can do.

  For this reason, as shown in the figure, when the telephone 1 is held and used on the desk of the desk 6 by the stand member 7 and the rubber feet 21, it is assumed that an excessive external force is applied to the telephone 1 from above. In addition, it is possible to prevent the stand member 7 from falling off or being damaged from the shaft support portion 15 and the casing. In addition, the protruding strip 10 formed with the rotation restricting portion 10 b for restricting the rotation of the stand member 7 in one direction is provided so as to extend in the width direction of the lower case 2. And since the intensity | strength of the protruding item | line body 10 improves, the drop-off | omission and the damage from the shaft support part 15 of the stand member 7 can be prevented more reliably. Similarly, by providing the rotation restricting portion 11a and the rotation restricting surface 19c for restricting the rotation of the stand member 7 in the other direction on both ends of the stand member 7, a torsional moment is applied to the stand member 7. Since it does not occur, it is possible to more reliably prevent the stand member 7 from falling off or being damaged from the shaft support portion 15. At this time, as shown in FIG. 5, since the movement restricting portion 17a of the elastic engagement piece 17 is engaged with the leg portion 25A of the stand member 7, the movement of the stand member 7 in the arrow A direction is restricted. Therefore, engagement between the recess 25a and the rotation restricting portion 11a and release of engagement between the leg portion 25B and the rotation restricting surface 19c can be restricted. Further, since the base member is not required as in the prior art and only the stand member 7 is required, the number of parts is reduced.

  In this embodiment, in order to restrict the rotation of the stand member 7 in the other direction, the two members of the rotation restricting portion 11a of the bearing member 11 and the rotation restricting surface 19c of the rotation restricting portion 19 are used. However, the rotation of the both ends of the stand member 7 is restricted by the above, but only one of them may be provided. In this case, the pivot 26 of the stand member 7 may be dropped from the opening 14 of the shaft support 15 due to an excessive external force applied to the telephone 1. Moreover, although the example of the telephone 1 has been described as an electronic device, the present invention can also be applied to various electronic devices that are used in a state where the casing is raised.
