Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates generally to parts of a pachinko machine, and more particularly to detection means for detecting passage of a pachinko ball.

In particular, it relates to a pachinko ball detection means that combines a mechanical switch and an electronic circuit.

[Prior Art] There is a sensor means for detecting an insertion hole when a pachinko ball enters the hole of the pachinko machine. Initially, a mechanical switch was used, but it was replaced with a non-contact type such as a photoelectric sensor in terms of chattering and durability of the contact itself of the switch.

[Problems to be Solved by the Invention] Although the cost of the photoelectric sensor and the like has become considerably low in recent years, further cost reduction is required in terms of the number of uses. Therefore, attention is paid to a simple mechanical switch. From the viewpoint of durability, the micro switch 1 is desired.
Is expensive and its size is large as shown in FIG. 5 (compared with FIG. 4 showing the present invention).

Furthermore, the problem of chattering cannot be solved as it is, as well as the problem of durability against heavy use.

[Means for Solving the Problem] In view of the above problems, the pachinko ball detecting means according to the present invention uses a simple mechanical switch, and the drawbacks of this mechanical switch are electronic means. I tried to make up for it. Hereinafter, a specific configuration of the pachinko ball detecting means according to the present invention will be described in detail.

First, the configuration of the first device will be described. The present invention first has a ball passage through which only one pachinko ball can pass at a time. Next is a mechanical switch. This mechanical switch is provided in the ball passage and operates when a pachinko ball passes through the ball passage.
Then there is the chattering prevention electronics. The anti-chattering electronics are coupled to the output of the mechanical switch. Finally, there is an electronic amplifier circuit. The electronic amplifier circuit inputs the output of the chattering prevention electronic circuit.

The mechanical switch described above consists of: First, there is Bocci. Next is the leaf spring. This leaf spring extends to the left and right from the above-mentioned bocchi, and normally, the bocchi is provided with its ball passage side (switch-off side).
When the pachinko balls pass through the ball passage, they are pushed to the fixed contact side (switch-on side). And there is a cushion spring. This cushion spring is provided at the other end of the bocchi. In addition, there are moving contacts. The movable contact is provided at the tip of the cushion spring. Finally, there is a pair of fixed contacts. The pair of fixed contacts oppose the movable contact.

Next, the configuration of the second invention will be described. The present invention first has a ball passage through which only one pachinko ball can pass at a time. Next is a mechanical switch. This mechanical switch is provided in the ball passage and operates when a pachinko ball passes through the ball passage.
Then there is the electronic amplifier circuit. This electronic amplifier circuit is coupled to the output of the mechanical switch. Finally, there is anti-chattering electronics. The chattering prevention electronic circuit inputs the output of the electronic amplifier circuit.

Since the above mechanical switch is the same as that of the first invention, the description of its configuration is incorporated herein.

[Operation] Since the pachinko ball detecting means according to the present invention has the above-described configuration, the following operation occurs.

First, the operation of the first device will be described. This invention, first of all, a ball passage through which only one pachinko ball can pass at a time,
Allow one pachinko ball to pass. Next, a mechanical switch is provided in the ball passage and is activated when the pachinko ball passes through the ball passage.

An anti-chattering electronic circuit is then coupled to the output of the mechanical switch to prevent chattering during the electronic output. Finally, an electronic amplifier circuit inputs the output of the chattering prevention electronic circuit and amplifies the electronic signal.

The operation of the above mechanical switch is as follows. First, the leaf spring normally pushes the bocce to the ball passage side, and when the pachinko ball passes through the ball passage, it is pushed to the fixed contact side. Further, since the cushion spring is provided at the other end of the bocchi and the movable contact is provided at the tip of the cushion spring, the movable contact is flexible to the fixed contacts by the cushion action. Connect to.

Next, the configuration of the second invention will be described. This invention, first of all, a ball passage through which only one pachinko ball can pass at a time,
Allow one pachinko ball to pass. Next, a mechanical switch is provided in the ball passage and is activated when the pachinko ball passes through the ball passage.

An electronic amplifier circuit then couples to the output of the mechanical switch and amplifies the electronic signal. Finally, a chattering prevention electronic circuit inputs the output of the above electronic amplifier circuit and prevents chattering during the electronic output.

Since the above mechanical switch is the same as that of the above-mentioned first invention, the description of its operation is incorporated herein.

[Embodiment] A pachinko ball detecting means according to the present invention will be described below in detail with reference to the accompanying drawings using an embodiment thereof.

FIG. 1 is an electronic circuit diagram of an embodiment of a pachinko ball detecting means according to the present invention. 2 and 3
The drawings are plan views of respective embodiments of the switch shown in FIG.

First, a ball passage 1 through which only one pachinko ball can pass at a time
There is 0. Next is the mechanical switch 20. The mechanical switch 20 is provided in the ball passage 10 and operates when a pachinko ball (not shown) passes through the ball passage 10. The mechanical switch 20 includes a botch 21 whose head protrudes into the ball passage 10, a leaf spring 22 that pushes the botch 21 toward the ball passage 10, and a cushion provided at the other end of the botchi 21. Spring 23, a movable contact 24a provided at the tip of the spring 23, and a movable contact 24a facing the movable contact 1
It consists of a pair of fixed contacts 24b, 24c.

It should be noted that, as in the embodiment of FIG.
As a pair, these contacts 24d and 24e and the above spring 2
Protrusion 25 is provided at the tip of 3 and the protrusion 25 and
The L-shaped movable piece 26 may be pivoted between 24d and 24e. In this case, the movement after the movement is the contact 24
The spring 23 can be omitted because d and 24e can be absorbed by bending.

Then, there is the electronic circuit 30. This electronic circuit 30 receives and processes the output from the above contact,
It is composed of a chattering prevention electronic circuit 31 composed of R and an electronic amplification circuit 32. The chattering prevention electronic circuit 31 and the electronic amplifier circuit 32 are connected in series,
The order does not matter.

[Effect of the Invention] Since the pachinko ball detecting means according to the present invention has the above-described configuration, the electric signal from the mechanical switch is amplified by the electronic amplification circuit. Therefore, since the switch only needs to cut off the weak electricity, it may have a structure of an inexpensive member. And the miniaturization was achieved.

In addition, this switch is very thin as shown in Fig. 5, not only can it be installed in a narrow space on a pachinko machine, but its configuration is also greatly simplified, greatly reducing its cost. Contributed.

Moreover, the anti-chattering electronics absorb the chattering caused by the mechanical switch, thus preventing miscounting and even delaying contact degradation.
