  As shown in FIG. 2, the sliding contact portion between the first pressing inclined portion 77a, 77b, 77b and the first sliding portion 87a, 87b, 87b is more than the main contact portion 70a, 70b. It is located at a position away from the center line Ox of 1 and on the edge of the operating body 6 on the Y1 side. The sliding contact portions between the first pressing inclined portions 78 and 78 and the first sliding portions 88 and 88 are located on the second center line Oy rather than the main contact portions 70a, 70b, 70c and 70d. The operation body 6 is located at the X1 side and X2 side edges. Furthermore, on the Y2 side of the operating body 6, the first pressing inclined portions 79a, 79b, 79b are provided at substantially the same position in the Y direction as the control inclined portions 73c, 73d.

  There are eight sliding contact portions between the first pressing inclined portions 77a, 77b, 78, 79a, 79b and the first sliding portions 87a, 87b, 88, 89a, 89b, and the main contact portion. More than the number of 70a, 70b, 70c, 70d.

Next, the operation of the pressing input device 1 will be described.
3, 4, 6, and 8 (A) show a non-operation state in which the pressing force in the Z2 direction is not applied to the operation body 6. In the non-operating state, the operating body 6 is raised by the urging force of the elastic body 4 in the upward direction (Z1 direction). In each of the main contact portions 70a, 70b, 70c, 70d, the control inclined portions 72a, 72b, 72c, 72d and the second sliding portions 82a, 82b, 82c, 82d formed on the guide member 5 slide. The guide member 5 is moved in the Y1 direction.

  As shown in FIG. 8A, the rising angle θ2 of the first pressing inclined portion 77b is larger than the rising angle θ1 of the control inclined portion 72b. When the distance between the contact point (a) between the first pressing inclined part 77b and the first sliding part 87b and the contact point (b) between the control inclined part 72b and the second sliding part 82b is L1. The distance between the inclined line La of the first pressing inclined portion 77b and the inclined line Lb of the control inclined portion 72b is always equal to the distance L1 in any place.

  Therefore, as shown in FIG. 8A, even if there is a gap δ between the main projection 71b formed on the operating body 6 and the hole 81b formed on the guide member 5, the operating body 6 When the control inclined portion 72b comes into contact with the second sliding portion 82b at the contact point (b) when the first sliding portion 87b rises in the Z1 direction, the first sliding portion 87b becomes the first sliding portion at the contact point (a). It abuts on the pressing inclined portion 77b.

  The control inclined portions 72a, 72b, 72c, 72d are provided at four locations, the first pressing inclined portions 77a, 77b, 78, 79a, 79b are provided at eight locations, and the operating body 6 and the guide member 5 are At least three contact points (a) and at least three contact points (b) always come into contact with each other, and rattling does not occur in the operation body 6 and the guide member 5 in a non-operation state.

  As shown in FIG. 3, the sliding protrusions 67, 67 formed on the operating body 6 slide along the edges 22b, 22c of the guide latching portions 22, 22, and the sliding protrusions 66, 66 also on the X1 side. However, it slides on the edge portions 21b and 21c of the guide latching portions 21 and 21, so that the operation body 6 can be operated only in the up and down direction (Z direction) without moving in the Y direction. In the non-operating state, as shown in FIG. 8A, the operating body 6 and the guide member 5 come into contact at the contact points (a) and (b), and the main projection 71b comes out of the hole 81b in the Z1 direction. The operating body 6 and the guide member 5 are fitted to each other so as not to be present. Therefore, the operating body 6 does not easily come off in the Z1 direction in the non-operating state.

  In particular, retaining portions 75a, 75b, 75c, and 75d are formed at the tip portions of the main protrusions 71a, 71b, 71c, and 71d, and the widths of the retaining portions 75a, 75b, 75c, and 75d are formed as shown in FIG. Since the dimension W1 is larger than the opening width of the holes 81a, 81b, 81c, 81d formed in the guide member 5, it is possible to further prevent the operating body 6 from coming off in the Z1 direction.

  However, as shown in FIG. 6, in the guide member 5, the third sliding portions 83a and 83b are thin portions 58, and second sliding portions 82a, 82b, 82c and 82d are formed. Since the portion is also a thin portion, when the main projections 71a, 71b, 71c, 71d are inserted into the holes 81a, 81b, 81c, 81d at the time of assembly, the thin portions are elastically deformed to assemble relatively easily. be able to. Further, when the operating body 6 is forcibly pulled up in the Z1 direction with a strong force, the thin-walled portion is elastically deformed, and the operating body 6 can be detached to disassemble the pressing input device 1.

  When the operating body 6 is pushed in the Z2 direction from the non-operating state, as shown in FIG. 8A, the descending force of the first pressing inclined portion 77b is guided in the guide direction (Y2 of the guide member 5 at the contact point (a). Direction). The rising angle θ1 of the second pressing inclined portion 73b is smaller than the rising angle θ2 of the first pressing inclined portion 77b. Therefore, immediately after the operating body 6 is slightly lowered and pushed by the first pressing inclined portion 77b and the guide member 5 starts to move in the Y2 direction, the second pressing inclined portion 73b is moved to the third sliding portion 83b. It hits. Thereafter, as shown in FIG. 8 (B), the first sliding portion 87b of the guide member 5 moves away from the first pressing inclined portion 77b as the operating body 6 moves downward, and the second pressing inclination. The guide member 5 is moved in the Y2 direction by the portion 73b.

  Thus, when the operating body 6 is pressed, the first sliding portion 87b is first pressed by the first pressing inclined portion 77b, and thereafter the third sliding portion 73b is pressed by the second pressing inclined portion 73b. Since the moving part 83b is pushed, even if there is a gap δ between the main projection 71b and the hole part 81b, the descending force of the operating body 6 is continuously moved without interruption and the moving force of the guide member 5 in the Y2 direction. Thus, the operating body 6 and the guide member 5 can operate smoothly without causing rattling.

  This operation is performed by contacting the other first pressing inclined portions 77a, 78, 79a, 79b with the other second pressing inclined portions 87a, 88, 89a, 89b, and the other second pressing inclined portions. The same applies to the abutting portions of 73a, 73c, 73d and the other third sliding portions 83a, 83c, 83d.

  When the guide member 5 moves in the Y2 direction, the second sliding portions 82a, 82b, 82c, 82d provided on the guide member 5 are controlled inclined portions at the four main contact portions 70a, 70b, 70c, 70d. 72a, 72b, 72c, and 72d are slid, and the pulling force in the Z2 direction is applied to the respective control inclined portions 72a, 72b, 72c, and 72d from the second sliding portions 82a, 82b, 82c, and 82d. Works. Since the pulling force in the Z2 direction acts on the operating body 6 at the four main contact portions 70a, 70b, 70c, and 70d when the operating body 6 is pressed, which position of the pressing portion 61 of the operating body 6 Even if is pushed, as shown in FIG. 7, the operating body 6 is lowered while maintaining the horizontal posture.

  As shown in FIGS. 2 and 6, first pressing inclined portions 77a, 77b, 77b are formed inside the side wall portion 62a on the Y1 side of the operating body 6. Therefore, as shown in FIG. 6, even if the operating force F1 is applied to the position where the edge of the operating body 6 on the Y1 side is biased, it is guided by the first pressing inclined portions 77a, 77b, 77b located immediately below. The member 5 is pushed in the Y2 direction, and the guide member 5 starts smoothly in the Y2 direction. Thereafter, the guide member 5 is moved in the Y2 direction by the four second pressing inclined portions 73a, 73b, 73c, and 73d, and the four control inclined portions 72a, 72b, 72c, and 72d are pulled in the Z2 direction. A force acts and the operating body 6 descends while maintaining a horizontal posture.

  As shown in FIG. 2, first pressing inclined portions 79 a, 79 b, and 79 b are provided immediately inside the side wall 62 b on the Y2 side of the operating body 6. Therefore, as shown in FIG. 6, even if the operating force F2 is applied to a position biased to the edge of the operating body 6 on the Y2 side, the first pressing inclined portions 79a, 79b, and 79b near the operating force F2 The guide member 5 is started in the Y2 direction, the guide member 5 can be moved in the Y2 direction, and the operating body 6 can be lowered while maintaining the horizontal posture.

  In this way, as shown in FIG. 6, the guide member 5 is guided in the guide direction (Y2 direction) regardless of the position of the operating body 6 applied to any position in the range L2 near the entire length of the guide member 5 in the Y1 direction. The operation body 6 can be lowered while maintaining the horizontal posture.

  Furthermore, as shown in FIG. 2, since the first pressing inclined portions 77b, 78, 79b are provided inside the side wall 63a on the X1 side of the operation body 6 and inside the side wall 63b, the operation body 6 Even when the X1 side edge portion or X2 side edge portion is deviated, the guide member 5 starts immediately in the Y2 direction, and the operating body 6 maintains the horizontal posture and moves down smoothly. It becomes like this.

  As shown in FIG. 7, when the operating body 6 is lowered, the upper sheet 32 of the switch mechanism 30 is pushed by the pressing portion 44 of the elastic body 4 shown in FIG. 9, and the movable contact 37 contacts the fixed contacts 36, 36. Then, the switch mechanism 30 is switched on.

  When the pressing force in the Z2 direction applied to the operating body 6 is released after the switch mechanism 30 is turned on, the restoring force of the elastic body 4 acts in the Z1 direction on the central portion of the operating body 6. To do. The operating body 6 moves in the Z1 direction in a stable posture with the center portion pushed. At this time, a force for guiding in the Y1 direction acts on the second sliding portions 82a, 82b, 82c, and 82d from the four control inclined portions 72a, 72b, 72c, and 72d, and the guide member 5 moves in the Y1 direction. And return.

Next, the structure of the press input device 101 according to another embodiment shown in FIG. 10 will be described.

  A press input device 101 shown in FIG. 10 includes an operating body 106 that moves in the up-and-down direction (Z1-Z2 direction) and a guide member 105 that moves in the Y1-Y2 direction. The operating body 106 moves in the Z2 direction. When lowered, a detection unit such as a switch mechanism operates.

  In the embodiment shown in FIGS. 1 to 9, the first pressing slope part, the second pressing slope part, and the control slope part are formed on the operating body 6. However, the press input device 101 shown in FIG. 10 is used. In the guide member 105, a first pressing inclined portion 177, a second pressing inclined portion 173, and a control inclined portion 172 are formed.

  The rising angle θ1 of the second pressing inclination portion 173 and the control inclination portion 172 is the same as the rising angle θ1 of the control inclination portion 72b shown in FIG. 8A, and the rising angle θ2 of the first pressing inclination portion 177. Is the same as the rising angle θ2 of the first pressing inclined portion 77b shown in FIG.

  The operating body 106 includes a first sliding portion 187 that slides with the first pressing inclined portion 177, and a second sliding portion that slides on both the second pressing inclined portion 173 and the control inclined portion 172. 182 is provided.

  In the non-operation state, the operation body 106 is urged and lifted in the Z1 direction by the elastic body 4. Since the first pressing inclined portion 177 and the control inclined portion 172 have different angles, the first sliding portion 187 and the first pressing inclined portion 177 come into contact with each other at the contact point (a). In (b), the 2nd sliding part 182 and the control inclination part 172 contact | abut. Therefore, rattling does not occur between the operation body 106 and the guide member 105.

  When the operating body 106 is pushed in the Z2 direction, the first pressing inclined portion 177 is pushed by the first sliding portion 187, and the guide member 105 starts to move in the Y2 direction. Immediately thereafter, the gap δ between the second sliding portion 182 and the second pressing inclined portion 173 is eliminated, and thereafter, the second sliding portion 182 slides on the second pressing inclined portion 173. The guide member 105 is moved in the Y2 direction, and the first pressing inclined portion 177 is separated from the first sliding portion 187. When the guide member 105 moves in the Y2 direction, a pulling force in the Z2 direction is applied to the second sliding portion 182 by the control inclined portions 172 provided at a plurality of locations. Therefore, no matter where the operating body 106 is pressed, the operating body 106 descends while maintaining a horizontal posture.
