Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pachinko ball counting machine, and in particular, a rotating body is rotated by the force of pachinko balls flowing down in a pachinko ball passage, and each time a predetermined number of pachinko balls are flown down, a counting device is used to count the number of pachinko balls. In a pachinko ball counting machine that counts the number of pachinko balls, the pachinko balls that are connected to the ball pot in the pachinko ball path are prevented from miscounting that may occur by pushing up the ball pot. It is related to.

[Prior Art] Conventionally, this type of pachinko ball counting machine has generally been used in conjunction with a ball lending machine in a pachinko game hall. In the ball rental machine, pachinko balls flow down the inside of the ball passage in a line, and a ball pot is installed downstream of the pachinko balls. The player then inserts money and pushes the ball jar upwards with his/her hand to open the ball rental gate in the ball jar and take out the number of rental balls corresponding to the amount of money.

A pachinko ball counting machine positions a part of a rotating plate within the pachinko ball path of a ball lending machine, holds pachinko balls one by one in multiple semicircular notches around the rotating plate, and rotates the rotating plate. By controlling this, a certain number of pachinko balls are allowed to pass downstream of the ball path.

The pachinko ball counting machine uses a solenoid as a driving source, and each time the rotary plate discharges a predetermined number of pachinko balls, the solenoid is driven and a stop disk attached coaxially with the rotary plate is activated. , a lock lever connected to the solenoid is engaged to stop the rotation of the stop disc, thereby stopping the rotation of the rotating plate.

Furthermore, the pachinko ball counting machine has a shield plate integrally formed with the rotary plate for counting pachinko balls on the same axis as the rotary plate, and the shield plate allows the detector installed nearby to The number of pachinko balls is counted by performing an on/off operation and notifying the control section in the ball rental machine of the signal output.

[Problem to be solved by the invention] In recent years, ball lending machines are equipped with high-value ball lending machines such as 1000 yen bills or 500 yen coins, and the number of balls dispensed into the ball pot increases as the amount increases. Become. In this case, the player does not take out all the rental balls from the ball jar at once, but instead takes out a portion of them and puts them into the saucer, then pushes the ball jar upwards again and removes the remaining rental balls. I often take it out. At this time, since the pachinko balls remain in the ball passage from the inside of the ball pot to the upper rotating plate and further upstream, the remaining balls are also pushed up at the same time, and as a result, the remaining balls are blocked by the rotating plate. The board rotates slightly in the opposite direction.

In this case, for example, the detection method is such that the rotary plate sends a detection signal once every five pachinko balls ejected, and the shield stops immediately after counting one cycle (counting five balls) to the detector. When the shield plate rotates in the opposite direction, there is a risk of false detection and miscounting. As a result, the number of balls that are said to have been ejected due to detection does not match the number of balls that were actually ejected,
There was a problem with the lack of precision in counting.

The present invention was made to solve such problems, and an object of the present invention is to provide a pachinko ball counting machine that can prevent the occurrence of false detection.

[Means for Solving the Problems] In order to solve the above object, the gist of the present invention is to: 1.

The clutch shaft 14a is fitted so that the protrusions 14b transmit rotation to each other and rotate together.

As shown in FIG. 7, among these members, the rotating body 13 has a notch 13a in its bearing portion with respect to the clutch shaft 14a indicated by a broken line, through which a protrusion 14b can be moved by rotation of the clutch shaft 14a. are doing. In addition, as shown in FIGS. 7 and 8,
A spring 21 is installed in the notch 13a to bias the protrusion 14b of the clutch shaft 14a. The notch 13a allows the protrusion 14b to turn into a rotating body when the rotating body 13 rotates in the forward direction (arrow B) and the opposite direction by the pachinko balls 11 pushed up inside the ball passage 12 when taking out the pachinko balls 11 from the ball pot 31. This allows the device to move without coming into contact with the object.

This notch 13a and a clutch shaft 14a forming a transmission shaft constitute a transmission section, and this transmission section allows the clutch 14 and the rotating body 13 to rotate when the rotating body 13 rotates in the forward direction (arrow B). They are in an engaged state with each other, and when the rotating body 13 rotates in the forward and reverse directions by the pachinko balls 11 pushed up inside the ball passage 12, they are in a non-engaged state with each other.

The clutch 14 includes a locking portion 3 for stopping rotation in the forward direction every time the rotating body 13 rotates in the forward direction (arrow B) and drops a predetermined five pachinko balls.
It has two 3's.

The backstop cam 19 is attached to the rotating body 13 by the clutch shaft 14a, and is configured to rotate as the rotating body 13 rotates in the forward and reverse directions. Back locking part 3 for stopping rotation in the opposite direction
This is a stop plate with two 5's.

In addition, as shown in FIG. 5, the clutch shaft 14a
is rotatably attached to the base plate 8 of the pachinko ball counting machine, and further attached to the base plate 8 are a control means, a counting means, and a driving means.

The counting means includes a detector 17 and a counter (not shown).
It has The detector 17 is a means for sending a signal when the switch is turned on, and the counter is a means for counting a predetermined number of five pieces in response to the signal from the detector 17.

The driving means includes a solenoid 16, and the solenoid 16 is a means for reciprocating the plunger 36 by being excited.

The control means includes a stop lever 15, a backstop lever 23, and a shutter lever 18.

As shown in FIGS. 1 and 2, the stop lever 15 is attached to the solenoid 16 at one end, and is swingable to the base plate 8 with a support shaft 22 so that the other end can engage with the locking portion 33 of the clutch 14. is attached to. When the stop lever 15 engages with the locking portion 33, it stops the forward rotation of the rotating body 13 via the clutch 14.

As shown in FIGS. 1 and 3, the backstop lever 23 has one end connected to the backstop cam 1.
It forms a locking pawl that can swing and engage with the back locking portion 35 by slidingly contacting the outer circumferential surface of the back locking portion 9 . The other end of the spring 24 fixed to is stretched by an engaging portion 41. When the back stop lever 23 engages with the back locking portion 35, it stops the rotation of the rotating body 13 in the opposite direction via the back stop cam 19.

The shutter lever 18 is attached to the protrusion 23a of the back stop lever 23 so as to be able to swing at a fulcrum 26, and has one end that can turn on and off the detector 17, and the other end that is attached to the protrusion 42 of the stop lever 15 so as to be able to turn on and off. movably mounted.

The shutter lever 18, as shown in FIG.
When the solenoid 16 is in the non-actuated state, the stop lever 15 engages with the locking portion 33 of the clutch 14, and the backstop lever 23 engages with the backlocking portion 35 of the backstop cam 19; When the detector 17 is turned off, the solenoid 16 is activated and the stop lever 1 is turned off, as shown in FIG.
5 disengages from the clutch 14 and becomes a disengaged state, and when the backstop lever 23 is disengaged from the back locking portion 35, the detector 1
It has an arrangement for switching on 7. The release lever 15a is integrally formed with the stop lever 15, and as shown in FIG.
The solenoid 16 is coupled to the solenoid 16 so that the solenoid 16 can be oscillated by being driven by the solenoid 16 to position the solenoid 16 in the non-driving state shown in FIG. As shown in FIG. 4, the release cam 20 has an outer circumferential shape that follows the release lever 15 in a direction to return the solenoid 16 to the non-driven state after the solenoid 16 is driven.

Next, the operation of the pachinko ball counting machine will be explained.

As shown in FIGS. 1 and 2, when the solenoid 16 is not driven before operating the ball lending machine, the stop lever 15 comes into contact with the locking portion 33 of the clutch 14, and the rotating body 13 moves in the forward direction (arrow B) is prevented from rotating. In addition, the notch 13 of the rotating body 13
The projection 14b of the clutch shaft 14a is brought into contact with the wall 43 of the clutch shaft 14a by the bias of the spring 21.

Further, the backstop lever 23 is in contact with a backlocking portion 35 of the backstop cam 19. At this time, the shutter lever 18 is
7 sensor is blocked and turned off. In this state, the pachinko balls 11 are lined up in the ball passage 12 and are stopped from flowing down by the pachinko ball holding section 31 in the ball passage 12.

When taking out rental balls from the ball lending machine 30, when coins are inserted into the bill insertion slot 1 or the coin insertion slot 2, a command signal for ejecting the pachinko balls 11 is output, which energizes the solenoid 16, as shown in FIG. As the plunger 36 is pulled, the stop lever 15 disengages from the locking portion 33 of the clutch 14, thereby releasing the stoppage of rotation of the clutch 14.

The input signal to the solenoid 16 activates the solenoid 16 by means of a drive pulse. This input signal may be a short drive pulse of a few milliseconds, as long as the drive pulse is long enough to disengage the stop lever 15 from the locking portion 33 of the clutch 14. Therefore, a small solenoid can be used, and the entire pachinko ball counting machine can be downsized.

The moment this engagement is disengaged, the shutter lever 18
As the stop lever 15 swings, the fulcrum 25
moves to the left in FIG.
The fulcrum 26 moves to the right in FIG. 3 by moving away from the fulcrum 25 and moving to the non-contact position, which causes the shutter lever 18 to rotate to the right in FIG. 3 about the fulcrum 25. By releasing the shield plate, the machine is switched from OFF to ON, and the counter counts the number of pachinko balls that have flowed down (5).

Since the stop lever 15 is disengaged from the clutch 14, the ball jar 31 is pushed up,
When you open the ball rental gate (not shown) inside the ball jar 31,
The rotating body 13 rotates in the forward direction (arrow B) due to the weight of the pachinko balls 11, and the pachinko balls 11 flow downstream of the ball passage 12.

At this time, when the rotating body 13 rotates in the forward direction (arrow B) due to the force of the pachinko balls 11 flowing down inside the ball passage 12, the clutch 14 is moved to the rotating body 13 via the clutch shaft 14a that is engaged with the rotating body 13. rotates with

After discharging the five pachinko balls 11,
Due to the elasticity of the spring 27, the stop lever 15 engages with the locking portion 33 of the clutch 14 at the half-rotated position, and stops the rotation of the rotating body 13 via the clutch 14 every time five pachinko balls are allowed to flow down. make it stop.

In addition, as shown in Fig. 4, the release lever 1
5a slides on the outer peripheral surface of the release cam 20,
By assisting in returning the plunger 36 to the non-driving state after the solenoid 16 is activated, the return operation of the plunger 36 is prevented from being delayed for any reason due to changes over time.

While the pachinko balls are being rented out by the ball lending machine 30, the pachinko balls 11 are in a state of being continuous in the ball passage 12 up to the ball jar 31. At this time, if the player releases the rented balls from the ball pot 31 and temporarily stops releasing the balls without taking out all the pachinko balls, the clutch 14 of the pachinko ball counting machine 10 causes the stop lever 1 to stop at the locking part 33.
5 may stop at a position where it is not engaged.

When the clutch 14 stops at a position immediately after the detector 17 detects a predetermined number of pachinko balls, five in this embodiment, that is, when the clutch 14 stops at a position where it starts the next five detection operations. In this state, when the player pushes the ball pot 31 upward to release the remaining rental balls, the pachinko balls 11 in the ball passage 12 are momentarily pushed upward slightly, and as a result, the pachinko balls 11 are momentarily pushed upward slightly. At the same time, the rotating body 13 is also pushed by the pachinko balls 11 pushed up inside the ball passage 12 and rotates in the reverse rotation direction (opposite direction of arrow B). At this time, the protrusion 1 of the clutch shaft 14a
4b moves against the spring 21 inside the notch 13a with respect to the rotating body 13 and is disengaged from the rotating body 13, so the clutch 14 moves against the rotating body 13.
Since the rotation of the rotating body 13 is not transmitted, neither of them rotates in the opposite direction, and only the rotating body 13 rotates in the opposite direction. Therefore, even if the pachinko balls 11 are pushed up inside the ball passage 12, the stop lever 15 and the back stop lever 18 do not swing, and the detector 17 is prevented from malfunctioning and erroneously detecting the ball.

Further, when the rotating body 13 rotates in the opposite direction by exceeding the length of play of the notch 13a, the backstop lever 23 slides into contact with the backstop cam 19 without engaging the backlocking part 35. By moving the fulcrum 26 to the right in FIG. 3 and moving the shutter lever 18 further away from the detection position of the detector 17, the detector 17
This prevents the switch from turning on and off to prevent erroneous detection due to the switch being turned off.

Therefore, the shutter lever 18 is connected to the solenoid 1.
Stop lever 15 immediately after giving input signal to 6
Erroneous detection by the detector 17 is prevented by two steps: the movement of the backstop lever 23 and the movement of the backstop lever 23 that moves vertically against the backstop cam 19.

[Effects of the Invention] According to the pachinko ball counting machine according to the present invention, even if the pachinko balls in the ball path are pushed up, only the rotating body rotates in the reverse direction, so that it is possible to eliminate the occurrence of false detection by the counting means.

In addition, if a shutter lever is provided, the shutter lever switches the detector on or off using a dual mechanism of a stop lever and a backstop lever, so that erroneous counting by the counting means is prevented regardless of the stopping position of the rotating body. be able to.
