DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to the embodiments shown in FIGS. 1 to 4
1 is a perspective view showing the appearance of a quadruple type switch unit, FIG. 2 is an exploded perspective view of the unit of FIG. 1, and FIG. 3 is one of the units of FIG. FIG. 4 is a plan view of a main part fracture showing a part, and FIG. 4 is a cross-sectional view taken along the line (4)-(4) of FIG.

The switch unit 1 shown in the figure has four switch bodies 3 in a single hard plastic case 2.
..And the structure incorporating levers 4, ...
The levers 4 corresponding to the pachinko balls 5 passing through the four through holes 23 formed in the case 2 ,.
The switch main bodies 3, ... Are operated via ... And the detection signals are individually output.

The case 2 is formed in a flat rectangular parallelepiped shape and comprises a case body 21 and a cover 22. The case main body 21 has four through holes 23 penetrating in the thickness direction at substantially equal intervals in the longitudinal direction in a rectangular region near the long side, and in the rectangular region near the other long side almost the entire width in the longitudinal direction. A concave portion 24 that extends over is provided. A part of each of the through holes 23 communicates with the recess 24. On the bottom surface of the recess 24, four sets of two pins 25 are assembled at approximately equal intervals in the longitudinal direction. The through hole 23 is
In order to make the contact area with the pachinko balls 5 which are the objects to be detected as small as possible and to reduce the passage resistance, they are formed in a substantially octagonal shape in plan view. The through hole 23 corresponds to the passage portion described in the claims. The cover 22 is detachably attached to the case body 21 so as to close the recess 24.

The switch main body 3 is formed in a flat rectangular shape, and a pin-shaped actuating piece 31 is provided on the front surface of the switch main body 3 so as to be retractable, and a detection signal is output on the rear surface by the operation of retracting the actuating piece 31. Two strip-shaped terminals 32 are provided so as to project. It should be noted that when the operating piece 31 is retracted, an internal contact (not shown) is switched, and after the pachinko ball 5 has passed, the operating piece 31 is elastically returned to the protruding state. .

The lever 4 is made of a quadrangular thin plate, and projections 41 serving as tilt fulcrums are formed at both ends of its upper side. The lower side of the lever 4 is curved in a round shape.

Next, the manner of mounting the switch body 3 and the lever 4 on the case 2 will be described. The switch body 3 is housed with the operating pieces 31 facing the through holes 23 at substantially equal intervals in the longitudinal direction of the recess 24 of the case 2. Each of the switch bodies 3 is positioned and held by being engaged with the pin 25 of the case 2. Lever 4 is case 2
Is attached to a notch that connects the through hole 23 and the recess 24 so as to be tiltable in a suspended state like "goodwill". That is, the protrusion 41 of the lever 4 is fitted into the groove 26 provided in the partition wall between the through hole 23 and the recess 24 of the case 2, and can be tilted about this protrusion 41 as a fulcrum. In this state, the operating piece 31 of the switch body 3
By this, almost the entire lever 4 is tilted in an oblique posture and is inserted into the through hole 23 of the case 2.

Next, the detection operation by the above-mentioned switch unit 1 will be described. That is, when the pachinko ball 5 passes through the through hole 23 of the case 2, the weight of the pachinko ball 5 causes the lever 4 to be tilted in the direction of arrow A in FIG. ,
The contacts (not shown) inside the switch body 3 are switched,
The detection signal is output from the terminal 32. And
After the pachinko balls 5 have passed, the operating piece 31 of the switch body 3 elastically returns to the protruding state, and the lever 4 returns to the original state.

Thus, the switch unit 1 of the present invention
Is a structure in which an arbitrary number of common switch bodies 3 and levers 4 are incorporated in a single case 2.
It suffices to change only the outer dimensions of the case 2 in accordance with the required number. For example, in the case of a triple type switch unit, as shown in FIG. 5, the case 2 has a structure in which three switch bodies 3 and levers 4 are housed. Again,
The basic configuration is similar to that of FIG.

That is, in the case of the switch unit 1 of the present invention, the width dimension W in the longitudinal direction of the case 2 is set to the switch body 3
It may be appropriately set according to the number of levers 4 stored. In short, in manufacturing, cases 2 having different width dimensions W, such as three stations, four stations, ... Are prepared, and the switch body 3 and the lever 4 are of a single standard. It suffices to prepare them, and by incorporating the required number of common switch bodies 3 and levers 4 in a single case 2 having an external dimension according to the requirements, it is possible to easily make variations such as two stations, three stations, ... Can be changed. Therefore, the switch unit of the present invention can be mounted on the device to be used with as few man-hours as possible, which can contribute to improvement in productivity of the device to be used. That is, when newly designing the switch unit 1 according to the number of uses of the switch body 3,
Only case 2 needs to be designed by increasing or decreasing the external dimensions.
By eliminating the need to change the design of the switch body 3 and the lever 4 at all, useless development costs can be eliminated, which can greatly contribute to the reduction of product prices.

The present invention is not limited to the above embodiment, and various applications and modifications can be considered.

(1) The lever 4 can be omitted. In that case, it is necessary to put the actuating piece 31 of the switch body 3 into an appropriate amount into the through hole 23 of the case 2.

(2) The switch unit 1 of FIG. 1 includes the case 2 having the four through holes 23 in which the switch body 3 and the lever 4 are housed in three or two instead of four. . That is, the number of switch bodies 3 and levers 4 stored in the case 2 may be equal to or smaller than the number of through holes 23 provided in the case 2.

(3) Perforations may be provided so as to partition the through holes 23 of the case 2 so that they can be separated from the perforations as necessary. In this case, for example, the switch unit 1 for 100 stations is manufactured, and then it can be appropriately separated into four stations, three stations, ...

(4) Appropriate connecting engaging portions may be provided at both ends of the case 2 in the longitudinal direction so that another case 2 can be connected. In this case, the number of stations can be appropriately increased, for example, the switch unit 1 for four stations can be connected to the switch unit 1 for four stations.

[0028]

According to the present invention, a plurality of switch bodies are made common, and only the case having a size according to the number of switch bodies used is selected and combined to detect a detected object. Various types of switch units having different numbers of rows can be easily manufactured at low cost, which can contribute to a reduction in product price.

When the switch unit of the present invention is used for detecting a pachinko ball of a pachinko gaming machine, for example, by using one switch unit as many as the number of rows of pachinko ball passages arranged in parallel, The number of installation steps can be greatly reduced compared to the conventional example, which contributes to the improvement of work efficiency. In addition, when the number of rows of pachinko balls is huge, it is not limited to using only one switch unit as many as the number of rows, and the number of rows is 1/2, 1
It is also possible to use a required number of switch units in a combination of / 3 ...
