Description

[Detailed Description of the Invention] The present invention relates to a reel device for a slot machine, and particularly to a reel device with an improved drive stop mechanism.

A so-called slot machine spins multiple reels (usually 3 to 4) with several different symbols (symbol marks) attached to the circumference of each reel, and after a random period of time has elapsed, or In this slot machine, players compete for points based on the combination of symbols displayed on each reel when they stop each reel at an arbitrary timing. The reel devices of such slot machines are required to first rotate each reel at a relatively high speed, then to stop them appropriately, and to determine the stopping position of each reel. . In conventional slot machines,
For this function, in particular for driving and stopping the rotation of the reel, a ratchet wheel is provided on the side of each reel. In other words, a ratchet wheel having a concave and convex portion of a pitch corresponding to the number of symbols provided on the circumference of the reel is integrally fixed to each reel, and when driving the ratchet wheel, an impact is applied by the starting lever of the slot machine. This ratchet wheel is struck by a drive pin that is displaced to . Therefore, the ratchet wheel is instantaneously urged to rotate by the drive pin, thereby causing the reel to rotate. Incidentally, at this point, the drive pin has naturally retreated from the rotation path of the ratchet wheel. When the reel is stopped, the stop pin is inserted into the rotation path of the ratchet wheel, and the stop pawl engages with the uneven portion of the ratchet wheel.

By the way, in such a structure of the conventional device, since the reel (ratchet wheel) is rotated and stopped mechanically and with an impact, the ratchet wheel,
Mechanical strength is first required for the drive pin and stop pin. Furthermore, the stopping position of the reel (ratchet wheel) needs to be such that the pattern attached to the circumference of the reel appears in the appropriate display window, so the uneven pitch of the ratchet wheel that is integrated with the reel must be adjusted. There are manufacturing disadvantages such as the need to match the pitch of the pattern display on the reel and the need to adjust the mounting position when integrating the reel and ratchet wheel. Furthermore, in the case where the reel and the ratchet wheel are manufactured as an integral part, the work of forming irregularities on the ratchet wheel becomes extremely complicated in terms of processing accuracy.

The present invention solves the above-mentioned problems of the conventional slot machine reel device, and is particularly characterized in that it does not use a ratchet wheel, which has many difficulties in manufacturing, assembling and adjusting. That is, according to the reel device of the present invention, the rotary reel is driven and stopped by a friction brake together with an integral detection disk (which may be the reel itself). Hereinafter, one embodiment of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a basic configuration diagram showing an embodiment of the present invention, and 10 is a reel body, which is rotatably supported by a shaft 20 with respect to the base of a slot machine (not shown). As shown in FIG. 2, several kinds of patterns M are arranged on the outer circumferential edge 11 of the reel body 10 at positions that equally divide the outer circumference. Furthermore, a rotating shaft 2 is provided on a disc 12 that is integrated with the reel body 10.
The openings 13 are formed at equal distances from 0, that is, on the circumference centered on the rotation axis 20. This opening 1
The number and arrangement pitch of 3 match the number of symbols M on the outer periphery of the reel and correspond to the arrangement pitch of the symbols M, and as will be described later, this disk 12 constitutes a detection disk. 30 is a photoelectric detector,
A light-emitting part and a light-receiving part are arranged with a disc 12 sandwiched therebetween in a direction perpendicular to the plane of the drawing, and a pulse output is generated each time the aperture 13 passes through this optical circuit as the reel rotates. Reference numeral 50 denotes a stop lever, which is swingable about a shaft 51 and has a wear-resistant shoe 52 fixed to one end thereof. Furthermore, the stop lever 50 is given a clockwise swinging force by the action of the coil spring 53, and
A long hole 54 is formed at the other end. A pin 62 fixed to a movable piece 61 of a solenoid 60 is engaged in this elongated hole 54 . It is assumed that the movable piece 61 of the solenoid 60 slides to the right in the figure when current is supplied to the solenoid 60. Further, 70 is a driving section for driving the solenoid 60 by generating a stop signal.

According to the above configuration, the slot machine is first started in the state shown in the figure, and the reel 10 is rotated in the direction of the arrow by, for example, a motor. During this rotation, the holes 13 provided in the disc 12 integrated with the reel 10 pass through the positions of the photoelectric detectors 30 one after another.
0 counts the number of holes 13 passing through. At this time, each time a slightly larger opening 15 passes, the detector 3
0 will detect a larger output than the others, and this will serve as a reference and be used as a reset pulse, so the number of holes passed through hole 13 can be determined from hole 15 to which hole it is. Therefore, if the positional relationship between the apertures 15 and the symbol display M on the reel is determined in advance, the number of apertures 13 passing through the detector 30 can be associated with the symbol display.

While the reel 10 is rotating, the operator presses the stop button (switch) of the slot machine.
When , the drive unit 70 is activated by this signal or via a stop program of the microcomputer.
is activated, and so the solenoid 60 is activated. As a result, the stop lever 50 rotates to the left against the coil spring 53 via the solenoid movable piece 61 and the pin 62, and the shoe 52 comes into sliding contact with the outer periphery 11 of the reel 10, causing the reel 10 to come to a frictional stop. By pressing the stop button mentioned above, or before pressing the stop button, the motor that drives the rotation of the reel 10 is stopped or the clutch of the rotation transmission system from the motor to the reel 10 is disconnected. With the reel 10 stopped in this way, the detection unit 30
counts how many pulses are generated and inputs this count signal to a microcomputer. Note that since three to four such reel devices are usually installed together, the microcomputer determines the score by determining the combination of count signals from each reel device. In addition, the photoelectric detector 3 is installed so that the position where the reel 10 stops is not between two symbol displays with respect to the symbol display window.
Pulse output from 0 and output of stop button
Input it to the AND circuit and calculate the logical product.
Solenoid drive unit 70 according to the output of the AND circuit.
, and adjust the brake action.

In this way, in order to stop the reel of the slot machine, the present invention simplifies manufacturing because it does not use any ratchet wheel, which requires machining precision as in conventional devices. Since the plate is completely integrated with the reel and the braking force can be applied directly to the outer circumference of the reel,
The reel device itself will be extremely simplified.
In addition, with the conventional ratchet wheel method, when the uneven parts of the ratchet wheel become worn out, it is complicated to replace the parts, and it is also necessary to display the reel pattern and adjust the position of the ratchet wheel. This is very advantageous since it is only necessary to replace the brake shoe.
