Description

[Detailed description of the invention] [Field of industrial application] The invention is for counting the number of pachinko balls supplied from the ball supply path into the prize ball storage tank provided at the upper part of the back of the pachinko game machine. Regarding the pachinko ball counter.

[Prior Art] Conventionally, as an example of this type of pachinko ball counter, there is a ball dropping passage, and the upper part of the ball dropping passage is connected to a ball supplying passage via a flexible tube (such as a coil spring). A sprocket-like rotating sprocket having teeth facing into the ball falling passage and rotating once every time a certain number of pachinko balls that fall through the ball falling passage pass is provided in the main body case. When the prize ball storage tank is empty, the rotating body is allowed to rotate and the pachinko balls start falling, and when the rotating body is rotated a predetermined number of times (in other words, a predetermined number of pachinko balls are A ratchet mechanism that prevents the rotation of the rotating body and stops the passing of pachinko balls, and a ratchet mechanism that stops the passing of pachinko balls by blocking the rotation of the rotating body, and a ratchet mechanism that prevents the pachinko balls from passing every time a permanent magnet installed on the rotating body rotates once (in other words, a certain number of pachinko balls pass). (every time)
A configuration is provided in which a reed relay is provided to generate one counting pulse. However,
In the conventional structure, the upper part of the ball falling passage of the main body case and the ball supplying passage are directly connected via a flexible tube, so that pachinko balls that fall quickly and have a relatively large mass, It may collide with the upper part of the ball falling passage in the main body case, which is usually made of plastic, and damage it.
If the damage progresses, the entire pachinko ball counter containing various mechanisms becomes unusable, resulting in a major problem. In addition, since the ball supply passage is provided in an inclined state from one end of the so-called island where the pachinko game machines are arranged in order to distribute the internal pachinko balls by gravity, the ball supply passage is At one end of the lower side of the passage, the clearance between the ball supply passage and the main body case may become extremely small.
If such a situation occurs, it will be very difficult to connect the ball drop passage of the main body case to one end of the lower side of the ball supply passage, and the pachinko ball counter will not work properly. This causes a problem that the installation work becomes troublesome.

[Purpose of the invention] The present invention was made in view of the above circumstances, and its purpose is to effectively prevent damage to the main body case caused by passing pachinko balls, and to simplify the installation work. To provide an effective pachinko ball counter.

[Summary of the invention] In order to achieve the above object, the present invention has a structure that is oriented in the vertical direction between the ball supply passage through which pachinko balls flow and the ball falling passage of the main body case, and whose lower end is connected to the ball falling passage. An L-shape integrally having a first cylindrical part communicated with the upper part and a second cylindrical part oriented in the left-right direction and whose tip is communicated with the ball supply passage in a state in which they communicate with each other. By providing a guide case and rotatably supporting the first cylindrical portion of the guide case at an appropriate stationary position, the force of the falling pachinko balls is temporarily received by the guide case, and the Second
The direction of the tip of the cylindrical part can be changed freely.

a, the pachinko balls from the ball supply passage 4 are prevented from accidentally falling outside the prize ball storage tank 2.

According to the present embodiment described above, since the L-shaped guide case 13 is interposed between the flexible tube 7 and the ball falling passage 9 of the main body case 8, the falling speed of the pachinko balls is determined by the falling speed of the pachinko balls. The pachinko balls are weakened by the case 13, and the pachinko balls do not directly collide with the vicinity of the ball falling path 9 in the main body case 8, thereby eliminating the possibility that the main body case 8 will be damaged. In this case, the pachinko balls will collide with the guide case 13 with great force, but since the guide case 13 is made of reinforced plastic, it is relatively difficult to damage.
In addition, even if the guide case 13 is damaged, only the guide case 13 needs to be replaced, which is much easier to repair than if the expensive main body case 8, which has parts such as a rotating body, ratchet mechanism, and reed relay, is damaged. Can reduce costs. In addition, guide case 13
Since the tip of the second cylindrical portion 13b, that is, the portion connected to the ball supply passage 4 via the flexible tube 7, can be freely changed in direction, the ball supply passage 4 and the main body are connected to each other. Even if the clearance between the pachinko ball counter 5 and the case 8 is extremely small, the connection between the ball supply passage 4 and the ball drop passage 9 of the main body case 8 can be easily made, and the installation work of the pachinko ball counter 5 can be simplified compared to the conventional one. There is no risk of such trouble.

The present invention is not limited to the embodiments described above and shown in the drawings, but can be implemented with various modifications without departing from the gist thereof.
