Description

  The present invention relates to an apparatus that is provided in a gaming machine such as a pachinko machine and brakes the flow speed of a sphere that is a gaming medium.

  In a pachinko machine, a ball such as a prize sphere is dispensed by providing a ball dispensing device composed of screws, sprockets, flickers, etc. in a spherical flow path in which a large number of aligned spheres flow down under their own weight. A sphere detector such as an optical sensor for detecting passage is provided, and when a predetermined number of spheres are counted by the sphere detector, rotation of the screw, sprocket, etc. is suddenly stopped, or flicker is projected into the sphere flow path. Therefore, it is trying to stop paying out the sphere.

  The speed of the sphere flowing down the spherical flow path is preferably as high as possible in order to increase the payout speed. However, if it is faster than a certain speed, accurate detection by the ball detector is difficult, or the response of the ball payout device May not be in time, and the sphere may be paid out excessively. For this reason, conventionally, the flow speed of the sphere has been reduced to a certain speed or less by meandering the spherical flow path.

In addition, the spherical body feeding device described in the following Patent Document 1 is configured such that acceleration due to the weight of the spherical body is prevented by providing an alignment path on which the spherical body flows down behind the rotation center of the sprocket.
Japanese Utility Model Publication No. 5-17110

  By the way, depending on the conventional braking means, it is impossible to freely set the sphere flow speed or change it as desired.

  Accordingly, the present invention is intended to provide a sphere falling speed braking device for a gaming machine in which the sphere falling speed can be varied and set as desired by magnetic braking means.

For this purpose, the sphere falling speed braking device of the gaming machine according to the present invention includes a driven rotator provided to rotate according to the sphere weight in a spherical flow path in which a large number of aligned spheres flow down, It comprises magnetic braking means that suppresses the falling speed of the sphere by braking the rotational speed with a magnetic force.
Further, the present invention is characterized in that, in the spherical body falling speed braking device, the driven rotor is constituted by a sprocket.

According to the present invention, in the sphere falling velocity braking device, the magnetic braking means is configured by opposing a permanent magnet and an electromagnetic coil, and the braking force is varied by controlling the energization state of the electromagnetic coil. It is characterized by that.
For this reason, it becomes possible to vary and set the sphere flow velocity as desired simply by controlling the energization state.

According to the present invention, in the sphere falling velocity braking device, the magnetic braking means is configured by facing a pair of permanent magnets, and the braking force can be varied by adjusting an interval between the permanent magnets. And
For this reason, it is possible to change and set the sphere flow velocity as desired simply by adjusting the interval between the permanent magnets.

  The flow speed of the sphere is properly controlled, and the sphere can be always dispensed at high speed without excess or deficiency. In addition, problems such as ball biting caused by an inappropriate sphere falling speed are also eliminated.

  FIG. 1 is a schematic diagram of the back side of a pachinko machine according to the present invention. In the figure, 1 is a premium sphere tank, 2 is an inclined rod that causes the spheres stored in the premium sphere tank to flow down by their own weight in an aligned state, An arc-shaped curved rail provided downstream of the inclined rod and turning the sphere in the vertical direction, 4 is a spherical flow path provided downstream of the curved rail, and 5 is a downflow according to the present invention provided in the spherical flow path A speed braking device 6 is a ball delivery device such as a screw type, a sprocket type, or a flicker type provided downstream of the falling speed braking device. A sphere passing through the ball delivery device passes through a delivery basket 7 and a delivery outlet 8. It is paid out to the ball tray in front of the pachinko machine.

  Next, an embodiment of the invention described in claims 1 to 3 will be described with reference to FIGS. The flow velocity braking device 5 has a sprocket 10 that is a driven rotating body provided at one end of a rotating shaft 9 that faces the outer circumferential claw portion of the sprocket 10 through a long hole 4 a formed in the side wall of the spherical flow channel 4. Thus, the bearing 11 is rotatably supported. Reference numeral 12 denotes a magnetic braking means in which a permanent magnet 13 is fixed to the rotating shaft 9 and an electromagnetic coil 15 facing the magnetic pole of the permanent magnet 13 is provided in the casing 14. Reference numeral 16 denotes a current control device provided at both ends of the conducting wire of the electromagnetic coil in order to control the energization state of the electromagnetic coil. The current control device 16 applies a predetermined voltage current from the outside between both ends of the electromagnetic coil 15 to excite the electromagnetic coil to a predetermined magnetic force, or short-circuits both ends of the electromagnetic coil 15 or a predetermined amount between both ends of the conductive wire. The electric resistance is controlled so as to be generated. S1 and S2 are sphere detection sensors provided in the sphere flow path 4, and the speed of the sphere P flowing down the sphere flow path 4 by the sensor (interval time between spheres continuously flowing down, sphere passing time) Etc.) can be detected.

  When the electromagnetic coil 14 is opposed to the permanent magnet 12 in this manner, the magnetic pole generated in the electromagnetic coil 14 during braking rotates the approach and separation of the permanent magnet 12, so that braking force is applied to the rotation of the rotating shaft 9. Thus, the rotational speed of the sprocket 10 can be reduced, and the flow speed of the sphere P flowing down the spherical flow path 4 with its own weight can be suppressed. Since the magnetic force generated in the electromagnetic coil 14 can be freely set and controlled according to the setting of the current control device 16, the flow speed of the sphere P can be freely controlled. For this reason, the ball P is always supplied to the ball dispensing device 9 at an appropriate speed, and excessive dispensing due to the flow velocity being too fast, or insufficient balls due to the flow velocity being too slow, or problems such as ball biting. Is resolved. The flow velocity is always detected by the sphere detection sensors S1 and S2 (by measuring the interval time between the continuously flowing spheres and the sphere, passage time, etc.), and the detected velocity is sent to the current control device 16. It is also possible to feed back and control the flow speed constant.

  On the other hand, FIG. 4 shows an embodiment of the invention as set forth in claim 4. The magnetic braking means 12 shown in this embodiment fixes the permanent magnet 13 to the rotating shaft 9 of the sprocket 10, and the permanent magnet 13. The permanent magnets 17 are opposed to each other with a gap g. For this reason, the rotation speed of the sphere P flowing down the ball flow path 4 with its own weight can be suppressed by reducing the rotation speed of the sprocket 10 by the magnetic force exerted on the permanent magnet 13 by the permanent magnet 17 during rotation.

Further, as shown in the embodiment of FIG. 5, if an electric actuator 18 for moving the permanent magnet 17 forward and backward is provided and the setting position of the permanent magnet 17 is changed, the distance g from the permanent magnet 13 can be adjusted. Since the magnetic force exerted on the permanent magnet 13 can be adjusted in a timely manner, this braking force can be freely varied.
In addition, although these Examples showed what the sphere P flowed down by the single line in the spherical flow path 4, it is needless to say that the sphere P may flow down in multiple lines.

  In the embodiment shown in FIG. 6, a meandering curve rail 3 is provided upstream of the flow velocity braking device 5 so that a large number of spheres can be made to stand by. The same part is shown. Further, the ball dispensing device 6 shown in this embodiment is a flicker-type ball dispensing device configured such that the flicker 6a appears and disappears in the ball flow path 4 by the operation of the solenoid 6b. Reference numeral 19 denotes a flow path switching valve for ball removal. S1 is a ball detection sensor provided for the purpose of confirming the existence of the payout ball number, and S2 is a ball detection sensor provided for counting the payout ball number.

  Further, the sphere falling speed braking device 5 shown in the first to fourth embodiments is provided separately from the ball paying device 6, but the embodiment shown in FIG. By providing the function of stopping the flow of the ball, it also has a function as a ball payout device. That is, a solenoid 20 is provided in the vicinity of a sprocket 10 that is rotatably supported so that the outer peripheral portion faces the spherical flow path 4, and an operating shaft 21 protruding and retracting from the solenoid can be engaged with the sprocket 10. By energizing the solenoid, the sprocket 10 can be rotated, and demagnetizing the solenoid stops the rotation of the sprocket 10 as shown in the figure. Therefore, by controlling the excitation time of the solenoid, A predetermined number of spheres are paid out. Note that S1 is a sensor that detects the number of balls dispensed. Also in this embodiment, by providing the rotating shaft 9 with the magnetic braking means as shown in the above embodiment, it is possible to brake the sphere falling speed simultaneously with the payout operation.
