Description

[Detailed description of the invention]

[0001] The present invention is based on the arrangement of symbol marks on a determination line when a plurality of endless belts or other rotating bodies displaying several types of symbol marks are arbitrarily stopped. The present invention relates to gaming machines such as spinning-type gaming machines, slot machines, and pachinko gaming machines that compete for profit and loss.

[0002]

[Prior art]

 Conventionally, gaming machines have been used in which a plurality of rotating bodies on which symbols are drawn are rotated so that when stopped, the symbols are matched by a determination line such as diagonal or horizontal. Japanese Utility Model Registration No. 2022641 has proposed a belt drive device for a game machine in which a belt having holes at intervals is controlled by a drive gear.

FIGS. 6 and 7 schematically show the belt driving device described in the specification of the same invention. The space inside the gaming machine is partitioned into three rooms by a partition plate 30. At the center of each chamber, three substantially cylindrical gears 31, 31, 31 are supported by the rotating shafts of stepping motors 32, 32, 32, respectively. Belt pulleys 34 and 35 are pivotally connected via a shaft 33 which is passed. An endless belt 36 is suspended over these gears and belt pulleys.

A large number of equally-spaced teeth projecting in the circumferential direction are provided on both peripheral edges of each gear 31, and these teeth are engaged with holes 36 a formed at both ends of the endless belt 36. The endless belt 36 is driven.

[0005]

[Issues to be solved by the invention]

 In such a belt driving device, a suspension device for suspending the endless belt is required in addition to the driving gears. Because the surface of the belt was almost smooth, there was a risk that the inner surface of the belt and the pulley were in constant contact friction and the belt was contaminated.

In a slot machine or a spinning-type gaming machine, a symbol mark appearing on a winning determination line when a reel is stopped is displayed on a belt with a light-blocking or light-transmitting chemical or paint on a belt, and light is emitted from the rear side of the reel. However, there was a problem that the display effect was hindered by soiling of the belt.

[0007]

[Means for Solving the Problems]

 According to the present invention, when a plurality of rotating endless belts are stopped arbitrarily, the symbol marks displayed on the belts contest whether or not to apply in a predetermined arrangement on a determination line. , A plurality of endless belts having holes formed at equal intervals, a set of drive control gears directly connected to a stepping motor for driving and controlling each endless belt, and at least one set of suspension gears for suspending each endless belt. The problem is solved by a belt drive device characterized by this.

In other words, by using a gear instead of a pulley for the belt suspension, the contact surface between the belt and the suspension is limited to both left and right ends where no symbol mark is displayed, so that the belt can be moved sideways. And prevent pollution.

[0009]

[Specific embodiments]

 Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

[0010]

FIG. 1 is a side view of a pair of belt driving devices according to a first embodiment of the present invention. In FIG. 1, reference numeral 3 denotes a mounting plate for partitioning the driving device into three chambers in the same manner as the partition plate 30, reference numeral 4 denotes a stepping motor housing portion, reference numeral 5 denotes a driving gear, reference numeral 6 denotes a rotation assist gear serving as a suspension, and reference numeral 7 denotes a light source device mounting space. It is.

In the present embodiment, unlike the invention of Utility Model Registration No. 2026441, the drive gear 5 is provided not on the inside of the display window but on the upper part of the drive device. A rotation assist gear 6 of a similar size is provided at the lower part of the driving device. The drive gear 5 is constituted by teeth provided on both peripheral edges of a cylindrical body at equal intervals in a circumferential direction and in parallel, and these teeth are inserted into holes 16 formed on both ends of an endless belt 14. The endless belt is suspended by meshing. A display window is provided on the left side of the light source device mounting space 7, and the symbol mark printed on the endless belt is displayed in the display window by irradiating the symbol mark from inside the device with the light source device.

FIG. 2 is a cross-sectional view of a rotation assist gear 6 serving as a suspension according to the present embodiment. Gears 12 and 13 having teeth provided at regular intervals on the periphery thereof are rotatably fitted on a rotating shaft 11 protruding from a predetermined position of the mounting plate 10. As an auxiliary tool for keeping the distance between the gears 12 and 13 and rotating the gears freely, a substantially cylindrical independent hollow pipe 14 is loosely fitted at a position intermediate between the gears 12 and 13 on the rotating shaft. . By meshing the teeth 12a and 13a around the gears with the holes 15a of the endless belt, the endless belt 15 is tensioned in the lateral direction, and can be hung around the gears 12 and 13. When the width of the endless belt 15 changes due to a change in the model or the like, it can be dealt with by replacing the hollow pipe 14 and changing the distance between the gears 12 and 13.

[0013]

Second Embodiment FIG. 3 shows another configuration of the belt driving device 6 of the present invention. As in the first embodiment, a rotation shaft 11 is provided at a predetermined position on the mounting plate 3. In the present embodiment, the gears 16 and 17 are disk portions 16b and 17b provided with teeth 16a and 17a at equal intervals on the periphery, respectively, and a substantially cylindrical rotary shaft guide 16c surrounding the rotary shaft 11 and protruding to one side. , 17c. The gears 16 and 17 are loosely fitted on the rotating shaft 11 with the rotating shaft guides 16c and 17c inside. Since the sum of the lengths of the rotary shaft guides 16c and 17c is substantially equal to the width of the endless belt 14, the change of the model can be dealt with by changing one or both of the gears 16c and 17c.

[0014]

Third Embodiment FIGS. 4 and 5 show a third embodiment of the driving device of the present invention. In this embodiment, the rotation assist gear 6 is provided at the center of the drive unit, and the rotation shaft 11 is provided at the center of the mounting plate 3 at a position slightly closer to the front of the gaming machine. A third suspension 18 smaller than the gears 5 and 6 is further provided at a lower portion of the mounting plate 3, around which an endless belt 14 is suspended.

FIG. 5A is a cross-sectional view of the rotation assist gear 6 according to the present embodiment. At the center of the rotating shaft 11, an attachment 20 such as a light source device including a shaft portion 20a, an attachment portion 20b, and a hood 20c is fixed facing the side facing the display window, and the light source device 21 is attached to the attachment portion 20b. ing. Gears 12 and 13 similar to those of the first embodiment are loosely fitted to the left and right of the light source device or other fixture 20 via a pair of hollow pipes 22 and 22, respectively. The change in the width of the endless belt 15 can be dealt with by replacing the hollow pipes 22,22.

When the endless belt 15 is suspended around the auxiliary gear and illuminated from the inside of the gear as in the present embodiment, the viewing angle at which the symbol mark can be visually recognized expands vertically as shown in FIG. There is an advantage that the display window can be easily recognized even when the display window is viewed from above or below depending on the physique and posture of the player.

FIG. 5B shows an example of the suspension 18 of the present embodiment. This suspension is a cylindrical pulley having no teeth on the peripheral surface, and the peripheral surface is provided with a guide flange 18a, a contact portion 18b, and a non-contact portion 18c which become lower in order from the side. The guide brim portion prevents the endless belt 15 from laterally shifting, and the endless belt 15 is wound around the inside of the contact portion 18b, but the non-contact portion 18c that hits the pattern area is recessed so that it does not easily contact the endless belt 15. It is configured. The configuration of the suspension 18 is not limited to this, and may be a gear-shaped configuration similar to the rotation assist gear 6.

[0018]

[Effect of the invention]

 In the belt drive device employing the gear type pulley of the present invention, the inner surface of the belt and the pulley do not constantly come into contact with each other, so that the belt is prevented from being stained and the endless belt-shaped symbol mark can always be clearly displayed. it can. Even when a cylindrical pulley is used for the suspension as in the third embodiment, the same effect can be expected because the main pulley is gear-shaped.
