Description

[Detailed Description of the Invention] This invention relates to a pachinko ball detection device used in pachinko machines and the like.

Conventionally, in a pachinko machine, a device for detecting an out ball is generally formed as shown in FIG. In the figure, a is the path through which ball b falls,
c indicates the constriction, d indicates the detection passage, and e indicates the detection device. As an example, this detection device e includes a light emitting device f and a light receiving device g, and also includes a light receiving device g.
An element that performs photoelectric conversion or changes electrical resistance due to light is used, and is connected to a counter (not shown). h is a tank. The falling or flowing ball b blocks the light emitted by the light emitting device f, and the counter counts the change that occurs in the light receiving device g due to this.

However, such a device has the following problems. This is because the balls b press against each other in the left and right directions in the narrowed portion o, engage with each other, and cause a so-called bridging phenomenon, and stop there, preventing the balls b from falling or flowing down.

This invention was made in order to solve such problems, and to explain this invention with reference to the drawings, in Figs. 2 and 3, the inner frame 2 and Outer frame 3
A plurality of divided passages 4 are provided, and each divided passage 4
This is a pachinko ball detection device characterized in that a pachinko ball detection device 5 is provided in each of the pachinko ball detection devices.

Note that in the figure, 7 is a light emitting device forming the detection device 5, and 8 is a light receiving device, as an example. The light emitting device 8 is a device capable of photoelectric conversion or a device whose electrical resistance changes depending on light, and is connected to a counter (not shown). Incidentally, the device 5 may be a coil or the like wound around this outer magnet. 9 indicates a ball tank, and 10 indicates a ball. Further, the divided passage 4 is formed into four parts as shown in FIGS. 2 and 3, and is made of transparent or translucent synthetic resin. The meaning of the above-mentioned semitransparent is that the light receiving device 8, which is installed in a substantially buried manner as shown in the figure, receives light emitted from the light emitting device 7, which is also provided in a generally buried manner, and transmits this light into a ball. The counter is translucent to the extent that the counter can count when it is blocked by a mask 10, and is formed in white as an example. Again 1
1 is a lid-shaped part, 12 is a platform-shaped part, and both 1
1 and 12 are fixed with bolts and nuts 13. Reference numeral 14 represents a housing portion formed between the two. The divided passage 4 is formed so that only one ball 10 can pass therethrough. Further, the relationship between the mounting positions of the light emitting device 7 and the light receiving device 8 is as shown in the third example.
Formed as shown in the figure. That is, one light emitting device 7 and four light receiving devices 8 were provided in correspondence. Further, the inner frame 2 may have a flat upper surface as shown in FIG. 2, or may have a substantially mountain-shaped cross section as shown in FIG. By forming it in this way, the falling or flowing ball 1
It would be possible to guide the balls 10 into the dividing path 4, or to divide the balls 10 that overlap in the left and right direction and fall or flow down. Further, the detection device 5 is provided, for example, in the outer frame 3 and inside the surface of the inner frame 2 in a substantially buried manner, so that the balls 10
This will help protect you from the effects of dust, etc. As shown in FIG. 6, the above-mentioned detection device
By using the mounting fittings 15, it can be attached to the reducing machine 16, etc., or by using the mounting feet 17 as shown in FIG. 7, it can be directly attached to the machine stand. 1 in Figures 6 and 7
8 is a reduction machine tank, 19 is a safe ball passage, and 20 is a supply ball tank. Further, the conductive wires of the light emitting device 7 and the light receiving device 8 are connected to a terminal 21 as shown in FIG. 3, and are connected to a power source, a counter, etc. using a socket 22, respectively.

Next, an example of a circuit connected to the light receiving device 8 of the detection device 5 is shown in FIG. In the figure, 23 is a ball detector, 24 is a waveform shaping circuit,
25 is a D-type flip-flop, 26 is a logic circuit,
27 is an oscillator, and 28 is a shift register.

The information of the light receiving element 8 temporarily stored in the D-type flip-flop 25 is transferred to the logic circuit 26.
The data are summarized and output as a series, which is displayed by a counter (not shown).

This invention has the following effects because it is constructed as described above. That is, the balls 10 falling or flowing down the passage 1 are guided by the inner frame 2, and if the balls 10 overlap in the horizontal direction,
to separate them from each other when they fall or flow down,
Since the balls 10 can be made to enter different divided passages 4, it is possible to prevent the so-called bridging phenomenon between the balls 10 from occurring. And thereby, the ball 10 can be detected reliably. Note that the detection device, as shown in FIG.
Alternatively, as shown in FIG.
There is no problem even if it is installed between the tank 9 and the tank 9, apart from both 1 and 9.
