Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an operating handle control mechanism in a slot machine or other coin-operated game machine, and more particularly relates to a sliding friction means in the operating handle control mechanism.

[Conventional technology]

As shown in FIG. 4, a typical slot machine has an operating handle 52 rotatably attached to an outer case 51, and the operating handle can be operated by inserting a coin from a coin slot 53.
By pulling the operating handle 52, the wheels 54a to 54c with various marks are started to rotate, and by pressing the wheel stop buttons 55a to 55c, the wheels 54a to 54c are stopped.

Locking means and locking means for a rotating member interlocked with a handle in a conventional slot machine are described in Japanese Utility Model Publication No. 61-21089. Its configuration will be explained based on FIG. 5.

The operating handle 52 is provided integrally with a handle shaft 56, and the handle shaft 56 passes through the outer case 51 (FIG. 4) and projects horizontally into an inner case 57 provided therein. Internal case 57
In this case, the rotating member 5 is integrated with the handle shaft 56.
8 is provided, which is the operating direction F of the handle 52.
Spring 5 in the handle return direction R opposite to
It is energized by 9.

To prevent the slot machine from being activated without the insertion of a coin, the operating handle 52 is controlled by an initial lock mechanism 60. In the initial lock mechanism 60, one end 62a of a lock piece 62 rotatably supported around a fulcrum 61 protrudes from the inner case 57, and the other end 62b is provided with a concave portion 63 formed at one end of the rotating member 58. can be engaged with. The lock piece 62 is
However, when a coin is inserted, the lock piece 62 rotates in the Y direction, and the engagement between the other end 62b and the concave portion 63 is released against the urging force of the spring 64, and the handle 52 and The rotating member 58 is maintained in a rotatable state in the F direction.

A reverse rotation regulating claw 65 is supported by the inner case 57 adjacent to the locking piece 62, and the regulating claw 65 is slidably engaged with a rack 66 formed continuously in the concave portion 63 of the locking piece 62. This prevents the lock piece 58 from rotating in the R direction. Further, the claw piece 67 protrudes from the lock piece 58 and slides into engagement with a restraining member 68 fixed to the inner case 57, so that the rotating member 58 is rotated.
Therefore, the handle 52 is prevented from being operated abnormally quickly.

In order to make the operator aware that the end of the handle operation is near, the second locking mechanism 70 operates in conjunction with the rotational movement of the rotational member 58. Second
The lock mechanism 70 includes a lock lever 72 pivotally supported by a pin 71, and a pin 74 integral with the lock lever 72.

6. Consists of a connecting member 77 that transmits the operation of the operating lever 76 to the lock lever 72. lock lever 7
A notch groove 78 is formed in 2, and the other end of the rotating member 58 can be engaged with and detached from the other end. Note that 79 is a stopper that restricts the return of the rotating member 58.

[Problem that the invention attempts to solve]

In the locking and unlocking means for the rotary member in the conventional slot machine as described above, since the rotary member 58 is integrally supported only by the handle shaft 56, the vicinity of both ends of the rotary member 58 are connected to the locking mechanism. It becomes deformed and worn out by repeated disengagement and long-term use. As a result, there is a drawback that the return movement of the handle is hindered. That is, there were problems such as the handle not rotating smoothly or stopping halfway when the handle returned.

Furthermore, in the conventional mechanism, in addition to the sliding relationship between the reverse rotation regulating pawl 65 and the rack 66, the pawl piece 67 and the restraining member 68 are also in a sliding relationship with each other, which causes the rotating member 58 to vibrate, which in turn causes the locking mechanism to 60,70
There is also a possibility that the engagement and disengagement relationship between the rotary member 58 and the rotary member 58 will be impaired.

In addition, the rotating pawl 67 of the rotating member and the stopping member 6
8 is in sliding contact with each other, it has been difficult to obtain an optimal rotational movement of the rotating member.

The purpose of the present invention is to overcome the above-mentioned drawbacks of the prior art, and in particular to facilitate the rotational movement of the rotating member.

[Means for solving problems]

Therefore, the present invention provides an operation having a rotating member whose handle shaft is supported by a frame through a bearing integrally with the operating handle, which rotates integrally with the handle shaft and is biased in the return direction of the operating handle by a biasing means. In the handle control mechanism, an oil pan is provided between the rotating member and the frame, the oil pan is fixed to the frame, and the handle shaft is rotatably supported with respect to the oil pan, and a sliding lubricant is installed inside the oil pan. By filling the oil pan with silicone grease and sealing it with the rotating member, the rotating member slides and rotates with respect to the silicone grease in the oil pan.

[Effect]

Silicone grease is supported by the frame, which is a stationary member, through an oil pan, and is in contact with the rotating member, which is a moving member, and silicone grease is ideal for rotating members due to its viscosity and good temperature characteristics. Demonstrates a friction function.

〔Example〕

FIG. 1 shows an operating handle control mechanism for a slot machine according to the present invention. In the figure, an operating handle control mechanism 1 is provided within an inner case 2, and the inner case 2 is composed of a frame 3 and a frame cover (not shown). The operating handle 4 is provided integrally with a handle shaft 5 that penetrates an external case 51 (FIG. 4) and projects into the internal case, and the handle shaft 5 is connected to the frame 3 via a bearing 6 (FIG. 2). It is rotatably provided.

A cam member 7 as a rotating member is fixed to the handle shaft 5 within the inner case 2, and rotates in the direction of arrow F together with the handle shaft when the handle is rotated. One end of a torsion spring 8 is connected to the cam member 7 or the handle shaft 5, and the other end of the torsion spring 8 is connected to a pin 9 that is implanted in a frame cover (not shown) and projects in the direction of the cam 7. By engaging, the cam member 7 is urged in the direction of arrow R. Further, one end of a coil spring 10 is connected to the cam member 8 in order to assist the biasing force of the torsion spring 8 in the R direction, and the other end of the coil spring 10 is connected to a pin 11 implanted in the frame 3.

The cam member 7 is formed with a notch 12 for preventing the handle from being operated before coins are inserted, and a locking member 13 constituting an initial locking mechanism is attached to be able to engage with this notch. The locking member 13 is provided so as to be rotatable about a pin 14 implanted in the frame 3, and is supported by a torsion spring 15 in the direction of the arrow X.
The cam member 7 engages with the notch 12 by being biased in the direction
prevents it from rotating in the F direction. That is, the start of operation of the operating handle 4 is prevented. Further, a solenoid 16 is provided on the frame 3, and when energized, the attracting piece 13a of the locking member 13 is moved to the solenoid 1.
The locking member 13 is pulled in six directions, and the pin 14 serves as a fulcrum when the locking member 13 and the notch 1 move in the opposite direction to X.
The engagement with 2 is released. The solenoid is energized in response to coin insertion. The above-mentioned pin 14 is further rotatably provided with one end portion of an arm 17, and the arm 17 is biased toward the cam surface of the cam 7 by the above-mentioned torsion spring 15. A roller 18 is rotatably attached to the other end of the arm, and the roller 18 is in constant contact with the cam surface. A spring 19 is connected to the other end of the arm 17 to ensure that the roller 18 is biased toward the cam surface. The locking member 13, solenoid 16, and arm 17 described above are all provided inside the frame 3.

The cam surfaces facing the roller 18 are a first cam surface 7a and a second cam surface 7 as shown in FIG.
b, has a third cam surface 7c. The second cam surface 7b is formed with a large curvature so as to provide discontinuity between the first cam surface 7a and the third cam surface 7c.

Regarding the handle shaft 5, a ratchet part 20 is provided at a position opposite to the notch 12 of the cam member 7 and the cam surfaces 7a to 7c, ratchet teeth 20a are formed at the end, and the handle shaft 5 is pivotally supported by the frame 3 or the upper cover. It engages with the claw member 21. A spring 22 is connected to the claw member 21. The ratchet part 20 is
Plate members 23 and 24 are fixed to both sides of the cam member 7, which protrudes outward in the radial direction. Stoppers 25 and 26 are erected and fixed on the frame 3, and cushioning members 25a and 26a made of rubber or the like are provided on the sides of each stopper facing the plates 23 and 24. The stoppers 25, 26 can be used as supports when attaching the upper cover (not shown) to the frame 3, and, for example, female threads 25b, 26b are formed in each of the stoppers 25, 26.

FIG. 2 is a sectional view of a main part of the operating handle control mechanism according to the present invention. A recess 5a is formed in the upper end of the handle shaft 5, and a rod member 27 fixed to the upper cover is slidably fitted into the recess 5a.
The handle shaft 5 is supported by the inner case 2 without wobbling. An oil pan 29 is provided between the cam member 7 and the frame 3.
is fixed to the frame 3 with screws 32 via a support 33. A hole 29a is formed in the bottom center of the oil pan 29, and a seal ring 29b is formed in the bottom center of the oil pan 29.
The handle shaft 5 is movably supported through the handle shaft 5. Silicone grease 31 is inside the oil pan 29.
The opening of the oil pan 29 is sealed by the cam member 7. An annular seal 30 is sandwiched between the upper edge of the oil pan 29 and the cam member 7 to prevent silicone grease from leaking. Incidentally, adjustment is made according to the amount of wear of the annular seal 30 by the forward and backward movement of the screw 32.
When the handle is operated, the handle shaft 5 and the cam member 7 rotate integrally, and the cam member 7 is in a sliding relationship relative to the surface of the silicone grease 31. Note that reference numeral 34 is a stop ring for restricting movement of the bearing 6 in the axial direction.

In the above configuration, when the user inserts a coin, the solenoid 16 attracts the locking member 13,
As a result, the engagement between the locking member 13 and the notch 12 is released. In this way, the operating handle 4 is ready to start operating. Next, when the user pulls the operating handle 4 toward the user, the cam member rotates in the F direction against the biasing force of the torsion spring 8 and the coil spring 10, and the roller 18 rotates and slides on the cam surface 7a ( 3A) The claw portion 21 separates from the plate 24 and clicks against the teeth 20a of the ratchet portion 20. If the user releases the operating handle during this process, the claw portion 21 engages with the tooth 20a of the ratchet portion 20 due to the biasing force of the spring 22, and the return rotation (in the R direction) of the cam member is prevented.

When the user further pulls the operating handle 4, the roller 18 comes into contact with the cam surface 7b of the cam member (third
Figure b). This allows the user to sense that a change has occurred in the continuous operating force of the operating handle, and to know that the handle operation is nearing completion (a so-called sense of withdrawal is given).

When the user further pulls the operating handle 4, the roller 1
8 rides on the cam surface 7c, and the plate 24 of the ratchet portion 20 abuts against the stopper 26. During this series of handle operations, the cam member 7 is always in sliding contact with the silicone grease 31, so that smooth rotational movement of the cam member 7 can be obtained from the initial operation state.

When the plate 24 is in contact with the stopper 26, the pawl 21 completely passes through the ratchet 20, and the urging force of the spring 22 reverses the pawl 21 as shown in FIG. 3C. Therefore, when the user releases the operating handle 4, the cam member 7 rotates in the R direction due to the urging force of the torsion spring 8 and the coil spring 10. At this time, the pawl portion 21 maintains the inclined state shown in FIG.
However, the rotation in the R direction is not prevented by the meshing of the claw portion 21 and the teeth 20a of the ratchet. However, while the handle 4 is returning, rotation in the F direction is prevented. Even during the return stroke of the cam member 7 in the R direction, the cam member 7 and the silicone grease 31
Due to the sliding contact relationship, smooth rotation of the cam member can be obtained from the initial stage of the return stroke.

The return movement of the cam member 7 in the R direction is caused by the movement of the plate 2
3 comes into contact with the stopper 25. (Figure 3 A).

〔effect〕

As described above, according to the operating handle control mechanism of the present invention, since the cam member, which is a rotating member, is also supported by the oil pan, stable cam operation can be obtained over a long period of time, and the cam Engagement and disengagement between the member and the initial lock mechanism, engagement and disengagement between the ratchet portion and the pawl portion, and sliding between the roller and the cam surface are performed smoothly. In addition, since the silicone grease in the oil pan fixed to the frame is always in sliding contact with the cam member, the cam member can rotate smoothly and the reliability of the entire device can be improved.
