Description

[Detailed description of the invention] The present invention relates to a ball breakage detection device for a prize ball case in a pachinko machine, and in particular, detects the state of a ball breakage in each of two rows of ball flow paths provided in a prize ball supply gutter. It is possible to detect each individual ball flow path using a switch.

An example of the implementation of the present invention will be described below with reference to the drawings. Reference numeral 1 denotes a prize ball case, which is a rectangular cylinder with vertical openings, and has prize ball storage chambers 1a and 1b vertically divided into two rows. The prize ball case 1 is pivotally mounted by a bearing 2 provided on the back, and is installed so that the prize ball case 1 can be freely swung back and forth by a solenoid 3 connected to the front. . 4 is a prize ball supply gutter, which is installed in communication with the top opening of the prize ball case 1;
Like the prize ball case 1, the ball flow paths 4a and 4b are separated into two rows, and the ball flow paths 4a and 4b are separated from each other in two rows.
Each ball is connected to two rows of prize ball storage chambers 1a and 1b provided in the prize ball case 1. Reference numeral 5 denotes a ball ejection gutter, which is installed in communication with the lower opening of the prize ball case 1, and 6, a prize ball ejection gutter, which is installed at a position adjacent to the ball ejection gutter 5, and which allows the prize ball case 1 to swing. Accordingly, the lower opening of the prize ball case 1 is installed so that it can be freely connected. 7 is a blocking plate installed between the prize ball case 1 and the ball extraction gutter 5;
The ball removal gutter 5 is opened by pivoting the blockage plate 7 at the base end of the ball case 1 and rotating the blocking plate 7 downward as necessary to allow the pachinko balls in the prize ball case 1 to flow out into the ball ejection gutter 5. be.

In the present invention, the prize ball supply gutter 4 is integrally provided with a fixing base part 9 on the top wall 8, and has vertical holes 10 and 11 penetrating through each of the ball channels 4a and 4b of the top wall 8, respectively. A switch 12 is fixedly installed on the upper surface of the fixed base part 9, and the switch 12 has a fixed contact 1 made of a conductive plate spring material and serves as a switch lever for operating the switch 12.
3 and the movable contact 14 are arranged vertically in parallel with a predetermined distance apart, that is, the fixed contact 13 is positioned on the lower surface and the movable contact 14 is positioned on the upper surface, and is formed by extending and projecting downwardly. On the left and right side walls of the fixed base portion 9, triangular plate-shaped ball breakage detection levers 15 and 16 are respectively installed with pivoting 17 at their apex corners.
Weights 22 and 23 are provided on the outer walls of the lower corner portions 20 and 21 on the outside of each of the outer corners 20 and 21, respectively, and a pressing pin 2 is provided on the inner wall of the outer lower corner portions 20 and 21.
4, 25 are formed in a protruding manner, and the weight of the weights 22, 23 allows the inner lower corners 18, 19 to freely enter the respective vertical holes 10, 11 of the prize ball supply gutter 4, and at the same time press pins 24 or 25, the movable contact 14 is pressed so that it can freely contact the fixed contact 13.

Since the present invention has the above-mentioned configuration, pachinko balls 26 are placed in each of the ball channels 4a and 4b of the prize ball supply gutter 4.
3, the ball breakage detection levers 15 and 16 are moved by the pachinko ball 26 against the weights 22 and 23 provided on the levers 15 and 16, as shown in FIG. The lower corner portions 18 and 19 are pushed out of the ball channels 4a and 4b, and the pressing pins 24 and 25 are placed at a position away from the movable contact 14. Therefore, each ball flow path 4a of the prize ball supply gutter 4,
While the pachinko ball 26 is present at 4b, the movable contact 14 and the fixed contact 13 are separated and the switch 12 is
It is turned off.

Next, when a ball runs out in either one of the ball flow paths 4a, 4b of the prize ball supply gutter 4, for example, the ball flow path 4
If the ball breaks at point a, as shown by the chain line in FIG.
0 into the ball flow path 4a, and at the same time the press pin 24 presses the movable contact 14 and brings it into contact with the fixed contact 13, thereby closing the switch 12.

Further, when a ball breakage occurs in the other ball flow path 4b, the ball breakage detection lever 16 operates in the same manner as the lever 15 to close the switch 12.

In this way, each ball channel 4a, 4 of the prize ball supply gutter 4
When a ball breakage occurs individually in each of the ball flow paths 4a or 4b, the switch 12 can be individually closed at the same time as the ball breakage state is detected individually for each ball flow path 4a or 4b. Then, by closing the switch 12, a command is sent to each required device to notify that the pachinko balls are out or to prompt them to replenish the supply.

Therefore, since the present invention is capable of individually detecting the cut-off state of each ball flow path in the prize ball supply gutter with a single switch, the electrical wiring can be simplified and the number of component parts can be reduced. There are advantages such as being able to
