【Example】

Next, we will discuss one embodiment of the prize detection mechanism of the prize discharge device for pachinko machines according to the present invention. This will be explained with reference to the drawings. The prize ejecting device shown in FIG. It incorporates internal components such as the detection mechanism 4 and is covered with a case 5. Ru.

[0009] The ejection device main body 1 is constructed by butting the first block 10 and the second block 11 together. It is formed by screwing several places, and the first and second blocks 10, A space formed vertically by spacer 11 is partitioned by spacer 12 to form first ball passage 1. 3 and a second ball passage 14 are formed, and a storage tank (Fig. (not shown), and a saucer (not shown) is provided below. Further, the first and second blocks 10 and 11 have press-fit holes 15 for the spacer 1. 2 is provided with grooves 16 at a plurality of locations, and the inner wall of each of the ball passages 13 and 14 is Opposing openings 17 are formed at two locations above and below. Ta However, the groove portion 16 is formed so that the spacer 12 is assembled to the blocks 10 and 11. This forms the press-fit hole 15.

0010 As shown in FIGS. 2 and 3, the ratchet wheel 2 has locking pawls 20 arranged at equal pitches on the outer periphery. A stop pawl 21 is provided between each lock pawl 20. This claw wheel 2 is rotatably attached to the ejection device main body 1 around a shaft 22, and has a locking claw 20. protrudes into the first and second ball passages 13 and 14 to lock the pachinko balls 40. The sea urchin is turning. Then, the ratchet wheel 2 is stopped by the ratchet stop mechanism 3, that is, Based on the excitation and demagnetization of the lenoid 25, the movable iron piece 26 is attracted and released in the directions of arrows A and B. When the tip part engages and disengages from the locking claw 20 or the stop claw 21, Rotate and stop.

[0011] As shown in FIG. 1, the prize detection mechanism 4 includes a holder 30, first and second detection cells. It consists of sensors 33, 34, a printed circuit board 35, etc. The holder 30 is made of a translucent material such as plastics and is molded into a substantially U-shape. Therefore, mounting holes 32 and 32 are formed in the arm portions 31 at both ends of the holder 30, respectively. It is.

0012 The first and second detection sensors 33 and 34 are light emitting elements (light emitting diodes) 3 3a, 34a, and light receiving elements (phototransistors) 33b, 34b, are press-fitted into the mounting holes 32, 32 of the holder 30, respectively, and both ends of the holder 30 are They are positioned so that they face each other. Note that the first detection sensor 33 is connected to the ball passage 1. 3, 14 is a sensor for detecting the presence or absence of prize balls, which is located above the second detection sensor 3. 4 is a sensor for counting prize balls located on the downstream side.

[0013] The prize detection mechanism 4 includes the light emitting elements 33a, 34a and the light receiving element 33b, 34b is integrated into the holder 30 and attached to one printed circuit board 35. After that, the both end arm portions 31, 31 of this holder 30 are inserted into the press-fit hole 15 of the ejection device main body 1. , 15 to be assembled by press fitting. As a result, the light emitting element 33a , 34a and the light receiving elements 33b, 34b are inserted into the openings of the inner walls forming the ball passages 13, 14. It can be accurately positioned at the mouth 17, and no deviation occurs in the optical axis. Moreover, the opening 1 7 is closed by the holder 30, and the inner wall surface is flush to prevent dust etc. from accumulating. Along with the stake, the detection sensors 33 and 34 are covered by the holder 30. This increases the withstand voltage and prevents malfunctions. In this way, the detection sensors 33, 34 can be efficiently assembled into the ejection device main body 1, and only one printed circuit board 35 is required. This makes it possible to reduce the number of parts.

[0014] In the pachinko machine prize ejecting device having the above configuration, as shown in FIGS. 2 and 3, , the prize balls 40 are lined up in a row in the first and second ball passages 13 and 14, and the prize balls at the bottom are 40 is supported by the locking pawl 20 of the ratchet wheel 2. In other words, the solenoid 25 is not energized. The movable iron piece 26 protrudes in the direction of arrow A due to the biasing force of the magnetic spring 27, and the The end is locked in the locking claw 20 or stop claw 21 (locking claw 20 in FIGS. 2 and 3). This prevents the ratchet wheel 2 from rotating. And in this state, the prize 4 0 is detected by the first sensor 33.

[0015] Here, if a pachinko ball enters a predetermined hole in a pachinko machine (not shown), the The lenoid 25 is energized and the movable iron piece 26 resists the urging force of the spring 27 and moves to the arrow B. direction, and the locking state between the tip of the movable iron piece 26 and the locking claw 20 is released. As a result, the ratchet wheel 2 becomes rotatable, and the ratchet wheel 2 rotates due to the weight of the prize balls 40, and the prize balls 40 fall naturally one after another. However, the second ball passage 14 is different from the first ball passage 13. In order to keep the prize ball 40 locked in the locking pawl 20 for only one pitch, , the prize balls 40 falling from the first ball passage 13 fall at different timings.

[0016] In this way, the falling prize balls 40 are sequentially counted by the second sensor 34. However, when the number reaches a predetermined value, the solenoid 25 is de-energized and blocks the rotation of the ratchet wheel 2. By stopping, the prize balls 40 are prevented from falling.
