Description

  The present invention relates to a multi-circuit pressing switch, in particular, a stacked multi-circuit pressing switch, and a correctness determination apparatus using the stacked multi-circuit pressing switch.

  In recent years, the use of a multi-circuit push switch has been expanded in which an operator can turn on and off a plurality of circuits by pressing a push button once. In particular, a stacked multi-circuit pressing switch is often used. Here, a multi-layer multi-circuit push switch is used as an example of a multi-layer two-circuit press switch that is used in a correctness determination device and detects conduction / non-conduction of an answer portion provided in a card inserted in the device. The prior art will be described.

FIG. 7 is an explanatory view of a conventional laminated two-circuit pressing switch.
(A) is a top view of the conventional laminated type 2 circuit press switch, (b) is an AA cross-section side view in the OFF state of the conventional laminated type 2 circuit press switch, (c) These are AA cross-section side views in the ON state of the conventional multilayer type two-circuit pressing switch.

  In (b), 50 is a movable contact and 51 is a fixed contact. The fixed contact 51 is fixed to the upper surface of the substrate 52 in the drawing in a conductive state. The substrate 52 is a double-sided printed circuit board. The upper surface pattern 52-1 covers the entire surface of the substrate 52, and the lower surface is divided into a non-conductive state between the lower surface pattern 52-2 and the lower surface pattern 52-3. 53 is a zebra contact. In the zebra contact 53, an insulating rubber layer and a conductive rubber layer are laminated in the order of an insulating layer 53-1, a conductive layer 53-2, an insulating layer 53-3, a conductive layer 53-4, and an insulating layer 53-5 ( Patent Document 1).

  On the upper surface of the zebra contact 53, the conductive layer 53-2 is the lower surface pattern 52-2 of the substrate 52, the insulating layer 53-3 is the boundary between the lower surface pattern 52-2 and the lower surface pattern 52-3 of the substrate 52, and the conductive layer. 53-4 are disposed in contact with the lower surface pattern 52-3 of the substrate 52, respectively. On the other hand, the lower surface of the zebra contact 53 is disposed in contact with a card (here, a conductor 55) inserted in the apparatus.

  A coil spring 54 is disposed between the movable contact 50 and the substrate 52 in a sandwiched state, and the movable contact 50 and the fixed contact 51 are maintained in an off state. Further, since the pressing force F by the operator is not yet applied to the zebra contact 53, the conductive layer 53-2 and the conductive layer 53-4 have a large resistance value, and the lower surface pattern 52-2 and the lower surface pattern 52-3 is maintained in the off state.

  Next, as shown in (c), when the pressing force F by the operator is applied to the movable contact 50, a part of the pressing force F is first accumulated in the coil spring 54, and the movable contact 50 and the fixed contact 51 are stored. Touch. In this state, the movable contact 50 and the fixed contact 51 become conductive, and the first switch (configured by the movable contact 50 and the fixed contact 51) is turned on.

When the operator further increases the pressing force F, this pressing force is accumulated inside the zebra contact 53. At this time, when the pressing force is equal to or higher than a predetermined pressure, the resistance values of the conductive layer 53-2 and the conductive layer 53-4 decrease. As a result, a current path of lower surface pattern 52-2 → conductive layer 53-2 → conductor 55 → conductive layer 53-4 → lower surface pattern 52-3 is generated and the second switch (the lower surface pattern 52-2 and the lower surface pattern 52− 3 is constituted by the boundary portion of 3). As a result, the conductor 55 on the card inserted into the apparatus is detected. When the conductor 55 is not present on the card, the passage is not formed, so that even if the operator increases the pressing force F, the second switch is kept off.

  The problem to be solved is that the multilayer type two-circuit pressing switch according to the above-described prior art has a large outer shape and is inevitably costly. Furthermore, since the operation order of the first switch and the second switch, and the operation delay amount between both switches are determined by the elastic characteristics of the coil spring and the zebra contact, it is almost impossible to control precisely. Sometimes the operation order is reversed and malfunction occurs.

  A first FPC that is divided at a predetermined position and has an off pattern that is non-conductive with each other; a second FPC that has an on pattern that contacts the off pattern and switches the off pattern to conduction; and the off pattern, and By stacking a spacer that maintains a predetermined gap between the first FPC and the second FPC while avoiding the contact portion of the on pattern, the first FPC, And the tension in the surface direction of the second FPC maintains the normal off state, and the pressing element presses the first FPC and the second FPC in the thickness direction, and the off pattern and the on pattern Is the largest feature of switching to the on state.

  The tension in the surface direction of the first FPC and the second FPC maintains a normally-off state, and the pressing element presses the first FPC and the second FPC in the thickness direction, Since the off pattern and the on pattern are brought into contact with each other and switched to the on state, the outer shape is reduced, and it is guaranteed that the off pattern is switched to the on state in order from the upstream in the movement direction of the presser. obtain.

As an example, the off pattern includes a lower surface pattern 2-1 having a comb-shaped pattern in the center portion of the first FPC 2 as shown by d-1 in (d), and a comb shape in the center portion of the first FPC 2 as well. It consists of a lower surface pattern 2-2 having a shape pattern. Both the comb shapes are formed so as to mesh with each other. The other tip portion of each pattern is connected to an external circuit to form a first switch circuit.

  The second FPC 3 is an FPC (flexible printed circuit) on the upper surface of which an on pattern is formed to contact the off pattern of the first FPC 2 and make the off pattern transition to conduction. As an example, the on-pattern is a rectangular pattern having a size sufficient to cover the entire surface of the off-shaped comb-shaped shape in the center portion of the first FPC 2 as indicated by d-2 in (d). Further, on the lower surface of the second FPC 3, an off pattern which is divided at a predetermined position and is mutually non-conductive is formed.

By this clamping pressure, the tension in the surface direction of the first FPC 2 and the second FPC 3 is maintained, and the normally-off state is maintained. Further, when the pressing element 1 applies a pressing force F in the thickness direction to the laminated body, the off pattern and the on pattern are brought into contact with each other to shift to the on state. As a result, the outer shape is reduced, and further, an effect is obtained that the first switch circuit and the second switch circuit are shifted to the ON state in order from the upstream in the movement direction of the presser.
