Abstract

PROBLEM TO BE SOLVED: To reduce a turn stroke of an operation knob and maintain a condition in which a lever member opens a ball extracting port by comparatively weak force by forming an outer peripheral end fringe of a receive part which comes in slide-contact with the operation knob in accordance with the pressing operation of the operation knob into an arc face expanding outward. SOLUTION: When an operation knob 22 at a chain line position is pressed by a finger in a condition in which a shutter part 21a of an opening and closing member 21 incorporated in an upper ball receive plate 7 closes a ball extracting port 19, the operation knob 22 turns in the clockwise direction using a support shaft 25 as a fulcrum to press an outer peripheral end fringe 31 of a receive part 23a of a lever member 23 by a lower face 27 thereof. Consequently, the lever member 23 turns against a spring 30 centered on a support shaft 28, and the opening and closing member 21 is slid in the left direction to open the ball extracting port 19. At this time, the force P1 for pressing the operation knob 22 continuously is small because it is preferably balanced with component force P21 of the force P2 for returning the lever member 23 by the spring 30 to improve the operation property.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball punching device for a ball tray mounted on the front of a pachinko game machine.

[0002]

2. Description of the Related Art Conventionally, there has been disclosed, for example, Japanese Utility Model Publication No. 4-21572 as a ball removing device for a ball tray of this kind. This conventional ball tray removing device is a device for removing the pachinko balls stored to be supplied to the ball launching portion. As shown in FIG. 12, an operation knob b is provided on the upper surface of a ball tray body a. An opening / closing member e, which is rotatably provided, and is constantly urged by a spring c to a position at which the ball extraction port d is closed by a spring c, and a lateral arm f, which contacts the lower surface of the operation knob b, is provided. An inverted L-shaped lever member i, which is integrally provided, and is pivotally supported by an engagement pin h protruding from the opening / closing member e with a lower end engagement hole g. By pressing the arm f of the lever member i by pressing the operation knob b to rotate the lever member i, the opening / closing member e
Is slid to a position where the ball extraction port d is opened, and the lever c is rotated by the bias of the spring c to hold the operation knob b at the original position.

[0003]

In the above-mentioned ball punching device, the lever member i is formed in an inverted L-shape, and the arm f and the lever member i are formed.
Leverage action to increase the sliding process of the opening / closing member e, and the operation knob b at the time of ball removal.
The rotation stroke of the ball is reduced so that the operation of extracting the pachinko balls stored in the ball tray main body a can be easily performed, and the space for installing the operation knob b can be sufficiently secured. However, since the arm f is shorter than the vertical height of the lever member i, and the arm f is pressed down by applying a force substantially at a right angle on the lower surface of the operation knob b, the lever member i is rotated by the bias of the spring c. A relatively large force is required from the beginning of the force to be applied to the operation knob b as it is, and the operation knob b must be continuously pressed with the large force while the ball is released. In combination with the small drop distance, the pushing force is loosened during the ball removal, and the opening and closing member e slides to the position where the ball removal port d is closed by the action of the spring c, and the ball removal is interrupted. There is a possibility that it will be lost, leaving room for improvement. Accordingly, the present invention has been made to solve the above-mentioned problem, and the turning stroke of the operation knob can be small, and the operation knob can be turned smoothly and the lever member can be removed with a relatively weak force. An object of the present invention is to provide a ball punching device for a ball tray in a pachinko game machine that can maintain a state in which a mouth is opened.

[0004]

In order to achieve the above object, a ball tray removing device for a ball tray in a pachinko game machine according to the present invention comprises a ball tray body for storing pachinko balls, and a ball tray body rotatably mounted on the ball tray body. An operation knob that is pivotally supported, a lever member that opens and closes the ball extraction port directly or via an opening / closing member by rotating with the operation knob in contact with the operation knob, and a ball extraction port The lever member has a receiving portion that protrudes from the support shaft toward the operation knob, and a receiving member that slides on the operation knob with the pressing operation of the operation knob. The outer peripheral edge of the stop portion is formed on an arcuate surface or flat surface that bulges outward, while the outer peripheral edge of the operation knob that is in sliding contact with the outer peripheral edge is formed on a flat surface or arcuate surface. However, the outer peripheral edge of the receiving portion and the outer peripheral edge of the operation knob may have an outwardly expanding arc surface and an arc surface, or an outer surface, provided that the lever member can be rotated by the pressing operation of the operation knob. It consists of a combination of an arc surface bulging inward and a flat surface, or a flat surface and an arc surface bulging outward.

Therefore, the contact point between the outer peripheral edge of the receiving portion and the outer peripheral edge of the operation knob is moved in a direction away from the rotation support shaft of the operation knob by the pressing operation of the operation knob.
Due to the moment, the force to press the operation knob with a finger is initially weak and gradually increases. In addition, the force that keeps pushing the operation knob should only be balanced by the force of the lever member that attempts to return to the original position by the urging of the urging member. Therefore, it is possible to smoothly rotate the operation knob, and to maintain a state in which the lever member opens the ball extraction port with a force smaller than the force of the lever member rotating by the biasing member.

A ball outlet 19 is provided at the bottom of the terminal of the rectifying passage 15, and a ball outlet 20 communicating with the lower ball receiving tray 8 is provided below the ball outlet 19.

Next, a ball punching device according to an embodiment of the present invention will be described with reference to FIGS. An opening / closing member 21 is provided in the ball outlet 19 so as to be slidable in the horizontal direction. The opening / closing member 21 has a flat shutter portion 21a for opening and closing the ball outlet 19 and an engaging pin 21b.
Is provided. An operation knob 22 and a lever member 23 are provided at a front position of the ball extracting port 19, respectively.

The operation knob 22 has a shaft through hole 2 on one side thereof.
4 is provided, and is rotatably supported by inserting a shaft through hole 24 into a rotation support shaft 25 protruding from the ball tray body 10. In addition, the upper part of the operation knob 22 rotates to rotate the upper surface wall 10.
The outer peripheral edge 27 of the lower surface contacts and is supported by the lever member 23. On the other hand, an upper portion of the lever member 23 is rotatably supported by a support shaft 28, and a vertically elongated hole 29 is formed at a lower end. The engaging pin 21b of the opening / closing member 21 faces the vertically long hole 29, whereby the operation knob 22 and the opening / closing member 21 can be interlocked via the lever member 23. Further, one end of a spring 30 as an urging member is connected to the lever member 23. The spring 30 urges the lever member 23 in the right direction in FIG. 5, that is, the direction in which the shutter 21 a of the opening / closing member 21 closes the ball outlet 19.

Here, the operation knob 22 and the lever member 2
3 will be described in more detail. That is, the lever member 23 has a receiving portion 23a that protrudes from the support shaft 28 toward the operation knob 22 and contacts and supports the operation knob 22. The receiving portion 23a is much shorter than the dimension from the support shaft 28 to the lower end of the lever member 23. And operation knob 22
Receiving portion 23 which comes into sliding contact with the operation knob 22 with the pressing operation of
The outer peripheral edge 31a is formed in an arc surface bulging outward.
On the other hand, the operation knob 22 that slides in contact with the outer peripheral edge 31
The outer peripheral edge 27 of FIG. 5 is formed on a flat surface on the upper right in FIG. 5 on condition that the lever member 23 can rotate by the pressing operation of the operation knob 22.

Next, the operation of the above-described ball tray removing device will be described with reference to FIG. First, when the operation knob 22 is pressed by a finger in a state where the shutter portion 21a of the opening / closing member 21 closes the ball extraction port 19 as shown by a chain line in FIG. 6, the operation knob 22 is turned as shown by a solid line in FIG. Swing shaft 2
The lever 5 rotates in a clockwise direction around the fulcrum 5 and pushes the outer peripheral edge 31 of the receiving portion 23 a of the lever member 23 with its lower surface, that is, the outer peripheral edge 27. As a result, the lever member 23 rotates clockwise around the support shaft 28 against the bias of the spring 30, and slides the opening / closing member 21 to the left to open the ball outlet 19. At this time, the contact point between the outer peripheral edge 31 of the receiving portion 23a and the outer peripheral edge 27 on the lower surface of the operation knob 22 moves away from the rotation support shaft 25 of the operation knob 22 (FIG. 6).
Then, from the start point 01 to the end point 02), the force of pressing the operation knob 22 with a finger is initially weak and gradually increases due to the relationship of the moment. Further, in the state where the operation knob 22 is pushed in, the force P1 that keeps pushing the operation knob 22 should be balanced with the component force P21 of the force P2 that tries to return the lever member 23 to the original position by the bias of the spring 30. , It gets weaker. Therefore, the operation knob 22 can be smoothly rotated, and the lever member 23 can maintain the state in which the ball extracting opening 19 is opened with a force smaller than the force of the lever member 23 trying to rotate by the bias of the spring 30.

Next, to close the ball extraction port 19, it is sufficient to release the finger from the operation knob 22. As a result, the lever member 23 is turned around the support shaft 28 by the bias of the spring 30 as shown by the chain line in FIG. The shutter 21a is rotated counterclockwise, and the opening / closing member 21 is returned to the original position shown by the chain line in FIG.
As a result, the ball outlet 19 is closed.

7 to 9 relate to another embodiment of the ball removing device. The same parts as those in the present embodiment are denoted by the same reference numerals, and description thereof will be omitted. In the ball removing device of FIG. 7, the outer peripheral edge 27 of the operation knob 22a that slides in opposition to the outer peripheral edge 31 that is an arc surface that bulges outwardly of the receiving portion 23a is pressed by the operation knob 22a. It is formed on an arc surface that expands outward on condition that the member 23 can rotate. When the operation knob 22a is pressed by a finger, the operation knob 22a rotates as shown by the chain line in FIG. 7, and the lower surface, that is, the outer peripheral edge 27 pushes the outer peripheral edge 31 of the receiving portion 23a of the lever member 23. I do. Also at this time, the contact point O between the outer peripheral edge 31 of the receiving portion 23a and the outer peripheral edge 27 on the lower surface of the operation knob 22a moves in a direction away from the rotation support shaft 25 of the operation knob 22a. When the lever is pressed, the operation knob 22a rotates smoothly because the force that continues to press the operation knob 22a may be balanced with the component force of the lever member 23 trying to return to the original position by the bias of the spring 30. Can and spring 30
, The lever member 23 can maintain a state in which the ball extraction opening 19 is opened with a force weaker than the force of the lever member 23 trying to rotate.

In the ball removing device shown in FIG.
The outer peripheral edge 27 of the operation knob 22b that slides in opposition to the outer peripheral edge 31 that is the arc surface that bulges outward from the operation knob 22b.
Is formed on the arc surface which is depressed inward on condition that the lever member 23 can be rotated by the pressing operation. When the operation knob 22b is pressed with a finger, the operation knob 22b rotates as shown by a chain line in FIG. 8, and the lower surface, that is, the outer peripheral edge 27 pushes the outer peripheral edge 31 of the receiving portion 23a of the lever member 23. I do. Also at this time, the contact O moves in the direction away from the rotation support shaft 25 of the operation knob 22b in the same manner as described above. In particular, in this case, since the outer peripheral edge 27 of the operation knob 22b is deeply recessed near the rotation support shaft 25, the initial force of the operation knob 22b is small, and the pressing operation becomes extremely smooth. Further, even when the operation knob 22b is pushed in, the force that keeps pushing the operation knob 22b may be balanced with the component force of the force of the lever member 23 returning to the original position by the bias of the spring 30, so that the operation knob 22b Can rotate smoothly and the spring 30 biases the lever member 2
The state where the lever member 23 opens the ball extraction port 19 can be maintained with a force weaker than the force of the rotation of the lever 3.

In the ball removing device shown in FIG.
The outer peripheral edge 27 of the operation knob 22c which slides in opposition to the outer peripheral edge 31 which is an arc surface bulging outward from the operation knob 22c.
Is formed on an arc surface that bulges outward on condition that the lever member 23 can be rotated by the pressing operation. In this case, in particular, unlike the above-described embodiments, when the operation knob 22c is pressed with a finger, the operation knob 22c rotates counterclockwise as indicated by the chain line in FIG. The outer peripheral edge 31 of the receiving portion 23a is pushed. Also at this time, the contact O is connected to the pivot 2 of the operation knob 22c in the same manner as described above.
Even when the operation knob 22c is pushed in the direction away from the control knob 5 and the operation knob 22c is pushed, the force that keeps pushing the operation knob 22c is balanced with the component force of the force of the lever member 23 returning to the original position by the bias of the spring 30. Therefore, the operation knob 22c can be smoothly rotated, and the lever member 23 can maintain the state in which the ball extracting opening 19 is opened with a force smaller than the force of the lever member 23 trying to rotate by the bias of the spring 30. . In this embodiment, the operation knob 22
c rotates in a counterclockwise direction by pushing, so that, for example, a ball extraction port 19 is provided at an opposite position,
Is slid to the right in FIG. 9 to open the ball extraction port 19.

FIGS. 10 and 11 show another embodiment in which the ball removing device according to the present invention is applied to the lower ball receiving tray 8. FIG.

That is, in the lever member 37 of this embodiment, the opening / closing member 21 and the lever member 23 of the present embodiment are integrally formed. The operation knob 22 is supported by a rotation support shaft 25 projecting from the support frame 34 so as to be horizontally rotatable, and a front portion thereof projects from an opening 39 of the support frame 34.

As in the case of the present embodiment, the lever member 37 has a receiving portion 23a projecting from the support shaft 38 toward the operation knob 22, and the lever member 37 slides in opposition to the outer peripheral edge 31. The outer peripheral edge 27 of the knob 22 is formed as a flat surface.

When the operation knob 22 is pressed by a finger in a state where the through hole 36, that is, the ball extraction port 33 is closed as shown by a solid line in FIG. Is pressed, the lever member 37 rotates clockwise as indicated by a chain line in FIG. When the finger is released from the operation knob 22, the lever member 37 is rotated by the bias of the spring 30 to return to the original solid line position shown in FIG. 11, and the ball extraction port 33 is closed. In this case, the operation knob 2 is also provided in the same manner as in the present embodiment.
