Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a symbol moving device of a slot machine, in which a winning or non-winning prize is determined by a combination of symbols displayed at a plurality of specific positions, more specifically, a pair of rotating bodies. The present invention relates to a symbol moving device of a slot machine in which a symbol belt is wound and the symbol belt is rotated by the rotation of the rotating body.

[0002]

2. Description of the Related Art The pattern moving device of the slot machine
Since the symbol belt is wound around a pair of rotating bodies, a fixed number of symbols are rotated along the rotation direction as compared to a symbol moving device that rotates a cylindrical reel in which symbols are arranged side by side in the circumferential direction. If you want to arrange them side by side, you can reduce the thickness of the symbol moving device to reduce the overall thickness of the slot machine, but conventionally, only one rotating body of a pair of rotating bodies is driven and rotated by a motor. The belt is rotationally moved, and the other rotating body is structured to rotate following the rotation of the design belt so as to guide the rotational movement of the design belt (for example, Japanese Utility Model Laid-Open No. 3-116871). reference).

[0003]

For this reason, there is a drawback that excessive tension is apt to be applied to the design belt when the design belt is started to rotate or stopped, and the durability of the design belt is impaired.
In other words, at the start of rotation of the design belt, even if one of the rotating bodies is driven and rotated by the motor, the other rotating body is stopped, so the other rotating body that is stopped is one rotating body. Resistance is given to the rotational movement of the design belt until it rotates at the same peripheral speed, and a large tension is generated in the design belt. Also, when the rotation of the design belt is stopped, the drive of the motor is stopped and one of the Even if only driving rotation of the rotating body is stopped, the other rotating body tries to rotate by inertial force, so the pattern belt whose rotational movement is stopped is forcibly pulled until the other rotating body stops. As a result, a large tension is generated in the design belt. The present invention has been made in view of the above circumstances, and by devising the rotating structure of the pair of rotating bodies, it is difficult to apply excessive tension to the design belt when starting or stopping the rotation of the design belt. , It is an object of the present invention to provide a pattern moving device of a slot machine capable of enhancing the durability of a pattern belt.

[0004]

The characteristic structure of the present invention for achieving the above object is to separately drive the pair of rotating bodies in a state of being synchronized with each other in the symbol moving device of the slot machine described above. The drive motor for rotating is provided so as to be able to simultaneously start and stop rotation of the pair of rotating bodies, and the following operational effects are obtained from such a configuration.

[0005]

When the design belt starts to rotate, both the pair of rotating bodies start rotating at the same time, so that a large tension is unlikely to be generated in the design belt, and when the design belt stops rotating, the pair of rotating bodies does not rotate. Since both sides stop rotating at the same time, it is difficult for large tension to be generated in the design belt.

[0006]

Therefore, when the pattern belt is started to rotate or stopped, the pattern belt is less likely to be subjected to excessive tension, and the durability of the pattern belt can be improved. The symbol moving device of the slot machine according to claim 2, wherein only one drive motor is provided, and each of the rotating bodies is individually linked to the drive motor, so that the rotation of only one drive motor is controlled. Only by doing so, it is possible to simultaneously start and stop rotation of the pair of rotating bodies, and simplify the control structure of the drive motor. In the pattern moving device of the slot machine according to claim 3, since the drive motor is arranged between the pair of rotating bodies, the drive motor can be assembled compactly by utilizing the inner space of the pattern belt. .

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 show a pattern moving device which is installed in a cabinet of a slot machine in a set of three units, and is mounted on a support column 2 standing on a base 1 via an arm 3 and a mounting substrate 4. Is fixed, and a pair of upper and lower rotating bodies 5 and 6 and a stepping motor M as a drive motor are attached to the mounting substrate 4, and the rotating bodies 5 and 6 are synchronously rotated by the driving of the stepping motor M. The design belt 7 wound around the rotating bodies 5 and 6 is configured to be rotated. In each of the pair of upper and lower rotating bodies 5 and 6, a pair of left and right pulleys 9 in which flange-shaped engaging pieces 8 for engaging with the design belt 7 are provided at regular intervals in the circumferential direction are fixed to the support shaft 10. And the upper and lower rotating bodies 5 and 6 so that the same peripheral speed can be obtained when they are rotated at the same number of rotations.
The rotating body 6 on the lower side is rotatably supported by a bracket 11 fixed to the mounting board 4 via a bearing 12, and the rotating body 5 on the upper side is mounted on the mounting board 4 with the same size. With respect to the gear case 13, which is slidably moved in the vertical direction, is rotatably supported via a bearing 14.

The stepping motor M is provided with upper and lower output shafts 15 and 16, is mounted on the lower surface side of a bracket 17 fixed to a mounting substrate 4, and has a lower output shaft 16 and a lower rotating body 6. Are interlocked via a screw gear 18, and the spline cylinder shaft 19 is fixed to the upper output shaft 15 in a state of penetrating the bracket bottom plate 20. The gear case 13 is such that a spline shaft 21 supported by a bearing 22 and an upper rotary body 5 are interlocked with each other via a screw gear 23. The spline shaft 21 is fitted to a spline cylinder shaft 19 and Rotating body 5 and stepping motor M
And are linked. A compression spring 24 is interposed between the bracket bottom plate 20 and the lower surface of the gear case 13, and is configured to urge the gear case 13 to be pushed up to apply tension to the design belt 7.

The pattern belt 7 has an H-shaped cutout hole 2
6, a series of loop-shaped strips 31 formed by punching at regular intervals in the circumferential direction, each of the plurality of hard symbol display plates 25 is bonded and fixed in a state of being located between the adjacent cut holes 26. In the portion to which the symbol display plate 25 is fixed, only the central portions on the left and right ends thereof are connected to the left and right connecting strips 27 wound around the pulley 9,
The engaging piece 8 provided on the pulley 9 is engaged with the gap formed between each symbol display plate 25 and the connecting strip plate 27, and is rotated by the rotation of the vertical rotating bodies 5 and 6. A tongue piece 28 is continuously provided at one location in the circumferential direction on both left and right edges to constitute a detected portion of a photo sensor (not shown) that detects the stop position of the design belt 7. On the attachment board 4, four idler rollers 29 are attached, each of which has a pattern belt 7 running on the front side of the slot machine and which is stretched in an arc shape in a side view.
The design belt 7 is mounted in the vicinity of the display window (not shown) on the front surface of the slot machine so as to run. Therefore, when the stepping motor M is driven at the time of starting the rotation of the design belt 7, both the upper and lower rotating bodies 5 and 6 start to rotate at the same time, so that a large tension is unlikely to be generated in the design belt 7, and the design belt 7 When the driving of the stepping motor M is stopped when the rotation of 7 is stopped, both the upper and lower rotating bodies 5 and 6 stop rotating at the same time, so that a large tension is less likely to be generated on the design belt 7.
