The respective sliding protrusions 64, 64 slide on the elevation guide surfaces 21 c, 21 c on both sides in the Y direction of the guide latching portion 21 formed on the substrate 2, and are further guided to the elevation guide hole 22. Since the sliding protrusions 64 and 64 are positioned so as to sandwich the guide latching portion 21 from both sides in the Y direction, the operating body 6 does not rattle in the Y1-Y2 direction and only in the ascending / descending direction (Z1-Z2 direction). It is movable.

  As shown in FIGS. 1, 4, and 5, the guide member 5 has recesses 58 formed at four locations. Each recess 58 penetrates the guide member 5 in the Z1-Z2 direction and is formed obliquely with respect to the Z1-Z2 direction. As shown in FIGS. 4 and 5, the operation body 6 is integrally formed with four protrusions 68 extending in the downward direction (Z2 direction) from the lower surface 61 a of the pressing portion 61. Each protrusion 68 extends obliquely with respect to the Z2 direction. Four recesses 58 and protrusions 68 form four engaging portions 70.

  As shown in FIG. 1, the four engaging portions 70 are arranged at two positions on both sides across a center line Ox that passes through the center of the operating body 6 and extends in parallel with the surface 2 a of the substrate 2. Two places are arranged on both sides of Oy.

  As shown in FIGS. 4 and 5, the recess 58 and the protrusion 68 constituting the engaging portion 70 are formed so as to be inclined in the Y1 direction as they descend in the Z2 direction. The portion 68 is slidably inserted into the recess 58 through a minimum gap.

  As shown in FIG. 4, in the two engaging portions 70 located on the Y1 side, a first contact portion 71 is formed on the Y2 side, and a fourth contact portion 74 is formed on the Y1 side. . The first contact portion 71 is formed by an inclined guide portion 71a formed on the Y2 side of the recess 58 and an inclined guide portion 71b formed on the Y2 side of the protrusion 68. The fourth contact portion 74 is formed by an inclined guide portion 74a formed on the Y1 side of the recess 58 and an inclined guide portion 71b formed on the Y1 side of the protrusion 68.

  In the two engaging portions 70 located on the Y2 side, the second contact portion 72 is formed on the Y1 side, and the third contact portion 73 is formed on the Y2 side. The second contact portion 72 is formed by an inclined guide portion 72 a formed on the Y1 side of the recess 58 and an inclined guide portion 72 b formed on the Y1 side of the protrusion 68. The third contact portion 73 is formed by an inclined guide portion 73a formed on the Y2 side of the recess 58 and an inclined guide portion 73b formed on the Y2 side of the protrusion 68.

Next, the operation of the pressing input device 1 will be described.
As shown in FIGS. 2, 3, and 4, when the pressing force in the Z2 direction is not applied to the operating body 6, the operating body 6 is separated from the substrate 1 by the urging force of the elastic body 4 in the Z1 direction. Is rising. When the protrusion 68 of the operating body 6 is raised, the inclined guide portions 71a, 72a, 73a, 74a formed on the operating body 6 and the inclined guide portions 71b, 72b, 73b, 74b formed on the guide member 5 are displayed. And the guide member 5 is moved in the Y1 direction.

  As shown in FIG. 3, when the operating body 6 is raised, the locking projection 52 a provided on the guide member 5 hits the inner edge of the locking long hole 21 a formed on the substrate 2 on the Y1 side. Thus, the guide member 5 cannot move in the Y1 direction any more. Further, the sliding protrusions 64, 64 provided on the operation body 6 are provided at positions sandwiching the guide latching portion 21 from both sides in the Y direction, and the operation body 6 is restrained from moving in the Y1-Y2 direction. Has been. Then, when the operating body 6 is raised, the four protrusions 68 formed on the operating body 6 do not come out of the recesses 58 formed on the guide member 5. From the above, the operating body 6 in a state where it is not operated does not come off in the Z1 direction.

  As described above, the range of movement of the guide member 5 in the Y1-Y2 direction is determined by the pair of guide latching portions 21 provided on the substrate 2, and the operating body 6 is moved up and down by the same guide latching portion 21. It is guided to. Therefore, the guide member 5 and the operating body 6 can be supported only by bending the pair of guide latching portions 21 on the substrate 2, and the structure of the substrate 2 can be simplified.

  When the pressing portion 61 of the operating body 6 is pushed down in the Z2 direction, the projecting portion 68 and the recessed portion 58 extending obliquely downward slide in the four engaging portions 70, and the guide member 5 slides in the Y2 direction. By doing so, the operating body 6 can be lowered while maintaining the horizontal posture.

  For example, as shown in FIG. 4, when the pressing force F1 is applied to a position biased toward the Y1 side with respect to the operating body 6, the first guide 71 located on the Y1 side guides the inclination of the protrusion 68. A downward force (a) is applied from the portion 71b to the inclined guide portion 71a of the concave portion 58, and the component force causes a sliding force (b) in the Y2 direction to act on the guide member 5, and the guide member 5 moves in the Y2 direction. Moved to. At this time, on the Y2 side, a downward guiding force (c) in the Z2 direction is applied from the inclined guide portion 72a of the recess 58 to the inclined guide portion 72b of the protrusion 68 at the second contact portion 72. Therefore, even if the pressing force F1 is applied to the Y1 side in a biased manner, a downward force can be applied to the operating body 6 on both the Y1 side and the Y2 side.

  On the contrary, as shown in FIG. 4, when the pressing force F2 biased to the Y2 side is applied to the operating body 6, the inclined guide portion 73b of the protrusion 68 is formed in the third contact portion 73 located on the Y2 side. A downward force (d) acts on the inclined guide portion 73a of the concave portion 58 from that, and a sliding force (e) in the Y2 direction acts on the guide member 5 by the component force, and the guide member 5 moves in the Y2 direction. To do. At this time, on the Y1 side, a downward guiding force (f) in the Z2 direction is applied from the inclined guide portion 74a of the recess 58 to the inclined guide portion 74b of the protrusion 68 at the fourth contact portion 74. Therefore, even if the pressing force F2 is applied to the biased position, it is possible to apply a downward force to the operating body 6 on both the Y1 side and the Y2 side.

  Therefore, the operating body 6 can be lowered in the Z1 direction while supporting the horizontal posture. When the operating body 6 is lowered, the upper sheet 32 of the switch mechanism 43 is pressed by the pressing portion 44 of the elastic body 4 shown in FIG. 6, the movable contact 37 comes into contact with the fixed contacts 36, 36, and the switch mechanism 43 is turned on. Can be switched to.

  When the pressing force in the Z2 direction applied to the operating body 6 is released after the switch mechanism 43 is switched ON, the restoring force of the elastic body 4 acts on the central portion of the operating body 6 in the Z1 direction. To do. The operating body 6 moves in the Z1 direction in a stable posture with the center portion pushed. At this time, in each of the engaging portions 70 on the Y1 side and Y2 side, an equal force is applied from the inclined guide portions 72b and 74b of the protrusion 68 to the inclined guide portions 72a and 74a of the concave portion 58, so that the guide member 5 becomes Y1. Move in the direction and return.

  As shown in FIG. 5, when the operating body 6 is lowered, the guide member 5 slid in the Y2 direction enters the space 63 of the operating body 6. Further, the lower end portion of the protrusion 68 provided on the operating body 6 enters the cutout portion 3 a of the membrane sheet 3 and the escape hole 23 of the substrate 2. Therefore, the operation body 6 can be lowered to a position where it substantially contacts the surface 2 a of the membrane sheet 3. Therefore, the height dimension from the surface 2a of the substrate 2 of the press-type input device 1 can be substantially matched with the dimension obtained by adding the thickness dimension of the operating body 6 and the descending stroke amount of the operating body 6. Can be configured.

  Furthermore, by adjusting the thickness of the guide member 5, the stroke when the operating body 6 is pressed can be changed. For example, if the guide member 5 is made thinner in FIG. 5, the stroke when the operating body 6 is pressed can be further increased.

  The pressing input device 101 of the second embodiment shown in FIG. 7 has the same basic structure as the pressing input device 1 of the first embodiment shown in FIGS.

  The press input device 101 shown in FIG. 7 has a membrane sheet 3 fixed under a metal substrate 102 with an adhesive or the like, and is formed of a light-transmitting synthetic resin material on the lower side of the membrane sheet 3. The light guide member 103 is installed. In addition, a light source such as an LED that provides light to the inside of the light guide member 103 is provided so as to face the end of the light guide member 103. An opening 102 a is formed in the substrate 102 above the switch mechanism 34 formed in the membrane sheet 3.

  When the operating body 6 is pressed in the Z2 direction and the elastic body 4 is compressed, the pressing portion 44 provided on the elastic body 4 passes through the opening 102a and presses the switch mechanism 34.

  By forming the base sheet 31 and the upper sheet 32 of the membrane sheet 3 with a translucent sheet and forming the elastic body 4 with a translucent synthetic rubber or the like, the light that has passed through the light guide member 103 is converted into the membrane. The sheet passes through the sheet 3 and the opening 102 a, passes through the elastic body 4, and is given to the operation body 6. If an illumination display unit that transmits light is provided in a part of the operating body 6, the illumination display unit can be illuminated.
