The cylindrical body 14 incorporates a ball 15 so as to roll freely in a lumen 143 defined by a first cap 141 and a second cap 142 defined by respective hemispherical depressions, and the caps 141 and 142 on the optical axis. Through holes 144 and 145 are formed in the central portion along the light beam, respectively. This is a switch that opens and closes when the light receiving device 13 detects the intensity of predetermined transmitted light from the light emitting device 12 from the light beam shielding state by the movement of the ball 15. A ball switch 1000 is provided, for example, on the surface of a base (not shown) via external connection terminals 122 and 132 drawn to the outside of the light emitting device 12 and the light receiving device 13, and the ball 15 rolls into the lumen 143. Since the light receiving device 13 detects the intensity of the transmitted light from the light emitting device 12 and opens and closes from the state where the light beam is shielded by moving, the rotating posture of the substrate can be detected.

As shown in FIGS. 1 to 6, the switch module 1 according to the first embodiment of the present invention generally includes a first frame 50, a second frame 20, a light emitting unit 30, and a light receiving unit 40. The movable member 60 is included.

  The first frame 50 has an outer surface 52 that is attached in a horizontal manner in contact with the surface of a flat substrate such as the printed wiring board 111. In this example, a first recess 57 is formed on the inner surface 51 back to back with the hollow portion 71 side of the first frame 50, that is, the outer surface 52, and the opposite side portions 53 and 54 of the first recess 57 are opposed to each other. A first recess 58 and a second recess 59 are formed by cutting perpendicularly to the optical axis O composed of the light emitting unit 30 and the light receiving unit 40.

  As shown in FIG. 5, the second frame 20 faces the inner surface 51 of the first frame 50 so as to define a hollow portion 71 in which the movable member 60 can be built by the first frame 50. It is provided as follows. A second recess 271 is formed on the inner surface 211 of the second frame 20 on the hollow portion 71 side so as to correspond to the first recess 57 and the first recess 57 to define the hollow portion 71. The first dent 57 and the second dent 271 are each formed in a hemispherical shape so as to define a spherical hollow portion 71, and the first dent 57 and the second dent 271 are formed on both opposing sides of the second dent 271.

  In this example, the movable member 60 is formed into a ball shape from a light-transmitting material and is movably incorporated in the hollow portion 71. The movable member 60 undergoes carcinogenesis as the printed wiring board 111 moves. The transmittance of the light beam passing along the optical axis O formed by the light emitting unit 30 and the light receiving unit 40 can be changed by jumping and bouncing.

  In a state where such a switch module 1 is electrically connected to the surface of the printed wiring board 111 by half attachment or the like, and the light emitter 32 is kept in a lighting state, a part of the light emitted by the light emitter 32 is the first. Light is emitted into the hollow portion 71 through one through-hole 72.

  The first frame 80 has a first groove-shaped recess 87 formed on the inner surface 81 on the hollow portion 74 side, and is perpendicular to the optical axis O on opposite side portions 83, 84 of the first groove-shaped recess 87. The first concave portion 88 and the second concave portion 89 are formed by notching.

  The second frame 20 has a second groove-shaped recess 281 corresponding to the first groove-shaped recess 87 on the inner surface 211 so as to abut against the first groove-shaped recess 87 to define a hollow portion 74. Each of the first groove-shaped recess 87 and the second groove-shaped recess 281 is formed in a semicircular shape so that the cross-section is formed into a circular tube shape. A first through-hole 75 having both ends opened on both side portions of the recess 281 facing each other with the first recess 88 and the second recess 89 corresponding to the first recess 88 and the second recess 89. And a third recess 282 and a fourth recess 283 defining the second through hole 76 are formed.

  The movable member 61 is incorporated in the tubular hollow portion 74 so as to be movable. In this example, the movable member 61 is formed of a non-translucent material, and shields light passing along the optical axis O formed by the light emitting unit 30 and the light receiving unit 40.

  When the switch module 3 is attached to the surface of the printed wiring board 111 and the light emitter 32 is maintained in the lighting state, the movable member 61 rolls and moves through the hollow portion 74 as shown in FIGS. The transmittance of the light beam that passes along the optical axis O formed by the light emitting unit 30 and the light receiving unit 40 can be changed. As described above, when the printed wiring board 111 moves, the switch module 3 blocks the light beam passing along the optical axis O formed by the light emitting unit 30 and the light receiving unit 40 by moving the movable member 61. Thus, the ON state and the OFF state can be switched, which is suitable as a tilt switch.

Blocks 801 and 201 for closing the respective one end openings are provided in the groove-shaped recess 281. In this example, the movable member 61 is made of an opaque material. With this configuration, when the printed wiring board 111 tilts and falls, the ball-shaped movable member 61 moves into the hollow portion 74, and when the printed wiring board 111 tilts to one side, the light beam that always passes along the optical axis O is transmitted. Since the light can be shielded and passed through the optical axis O only in one direction, the ON state and the OFF state can be switched. Therefore, the switch module 4 of this example is suitable as a one-way tilt switch.

  According to the switch module 4 of this form, it has the same effect as the switch module of the said example.

In this way, similar to the switch module of the above-described embodiment, the movable member 61 rolls and moves to block the light beam that passes along the optical axis O formed by the light emitting unit 30 and the light receiving unit 40. Can do.

  In the switch module 5, as shown in FIGS. 23 to 25, when the printed wiring board 111 falls, the movable member 61 rolls and moves along the optical axis O formed by the light emitting unit 30 and the light receiving unit 40. It is possible to switch between the ON state and the OFF state by shielding the passing light. This switch module 5 is suitable as a tilt switch.
