Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a slot machine reel on which symbols are displayed.

[0002]

2. Description of the Related Art In a slot machine, for example, three reels arranged on the outer periphery of a symbol are driven by a motor, and when these are stopped, a combination of symbols stopped on a winning line is used to compete for a prize. It is widely known as a game console. Players 1-3 at the start of the game
When a number of medal lines are selected by throwing in medals and a prize is obtained on the activated pay line, medals corresponding to the kind of the medal line are paid out.

Most of recent slot machines have a structure in which a reel is driven by a stepping motor, and the rotation and stop of the reel are controlled by controlling the driving of the stepping motor. Therefore, it is necessary to keep the reel lightweight in consideration of the responsiveness at the time of starting and stopping the reel.

From such a background, conventional reels for slot machines have a symbol strip in which a plurality of symbols are arranged on a strip-shaped plastic sheet at a constant pitch.
It is attached to the peripheral surface of a cylindrical reel body made by plastic molding with an adhesive, a pressure-sensitive adhesive or a double-sided tape. Further, recently, in order to further reduce the weight of the reel, two annular strip holding frames are used instead of the reel body, and the side edges of the symbol strips are adhered to the outer circumferences of these strip holding frames. Some are in reel form.

[0005]

However, since the slot machine reels produced as described above are rotated at a high speed during the game, they are firmly adhered so that the symbol strips do not separate during the rotation. Must be
It has the drawback that it is easy to assemble.
The symbol strips may need to be replaced in order to change the specifications of the slot machine or change the interest of the game. In such a case, if the symbol strip is firmly adhered to the strip holding frame, the replacement work becomes very troublesome, and the strip holding frame may be damaged during removal.

The present invention has been made in consideration of the above problems of the prior art, and an object thereof is to provide a reel for a slot machine which is easy to assemble and which allows easy exchange of symbol strips. To aim.

[0007]

In order to achieve the above-mentioned object, a protrusion 2 having a constant width is provided on the outer periphery of a strip holding frame so as to sandwich the side edges of the symbol strip from the front and back sides.
The holding pieces of the row are integrally formed. Further, in claim 2, among the two rows of holding pieces, the holding pieces on the front surface side of the symbol strip are continuously formed in an annular shape, and the holding pieces on the back surface side of the symbol strip are intermittently opened at a predetermined interval. It was formed in a proper manner. Further, in claim 3, a pin is made to protrude from the inner wall of the other holding piece facing the part where the holding piece on the back side of the symbol strip is omitted, and this pin is fitted into the hole provided in the symbol strip. It is a thing.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is an exploded perspective view of a slot machine reel according to the present invention. The reel 1 includes a symbol strip 2 and strip holding frames 3 and 4. The symbol strip 2 is made of a thin strip-shaped plastic sheet, and various symbols such as fruits, numbers and English letters are printed on the surface. Further, the end portion 7 of the symbol strip 2 is adhered with an adhesive tape and kept in an annular shape. Furthermore, along the both side edges of the symbol strip 2,
The holes 8 are formed at a predetermined interval.

One of the strip holding frames 3 is formed of hard plastic in an annular shape, and an outer holding piece 10 which stands up at a right angle with a constant width is provided around the outer circumference of the strip holding frame 3.
Inside the outer holding piece 10, an inner holding piece 11 is integrally provided with a predetermined gap so as to face the outer holding piece 10. The inner holding pieces 11 are intermittently provided at predetermined intervals as illustrated. The gap between the outer holding piece 10 and the inner holding piece 11 is slightly wider than the thickness of the symbol strip 2. Further, the outer holding piece 10 is provided with a pin 13 so as to project inward at substantially the center of the place where the inner holding piece 11 is omitted.

The other strip holding frame 4 is formed of hard plastic into an annular shape like the strip holding frame 3 described above. Then, along the outer periphery thereof, similarly to the outer holding piece 10 and the inner holding piece 11 of the strip holding frame 3,
A continuous outer holding piece 15 and an intermittent inner holding piece 16 (see FIG. 2) are integrally formed, and a gap 17 is formed between them. Further, the outer holding piece 15 includes the inner holding piece 1
A pin 13 is provided so as to project inward at approximately the center of the portion where 6 is omitted.

FIG. 2 is a sectional view of a reel for a slot machine embodying the present invention. The symbol strip 2 on which the symbol 6 is displayed is sandwiched at one side edge portion thereof by the outer holding piece 10 and the inner holding piece 11 of the strip holding frame 3, and further attached to the outer holding piece 10 with a double-sided tape. In addition, the pin 13 protruding from the outer holding piece 10 and the hole 8 are engaged with each other, so that the symbol strip 2 is firmly held by the strip holding frame 3 at one side edge portion.

The other side edge portion of the symbol strip 2 is also sandwiched between the outer holding piece 15 and the inner holding piece 16 of the strip holding frame 4, and is further attached to the outer holding piece 15 with a double-sided tape. By engaging the pin 13 protruding from the outer holding piece 15 with the hole 8, the symbol strip 2 is firmly held by the strip holding frame 3 at the other side edge portion.

Next, the operation of these embodiments will be described.
When changing the winning pattern of the slot machine or changing the symbol strip 2 of the reel 1 in order to change the interest, first remove the reel 1 from the slot machine and then remove the symbol strip 2 from the reel 1. Become. At this time, as shown in the cross-sectional view of FIG. 2, one side 2a of the symbol strip 2 is sandwiched between the outer holding piece 10 and the inner holding piece 11 of the strip holding frame 3,
The other side 2b is sandwiched between the outer holding piece 15 and the inner holding piece 16 of the strip holding frame 4, and the symbol strip 2 is attached to the outer holding pieces 10 and 15 with double-sided tape. But inside holding piece 1
Since 1 and 16 are provided intermittently, if the strip holding frames 3 and 4 are pulled from the symbol strip 2, the symbol strip 2 can be easily removed without destroying the strip holding frames 3 and 4. .

Next, when attaching a symbol strip having a new pattern, both side edges of the symbol strip 2 are attached to the outer holding piece 10 and the inner holding piece 11 of the strip holding frame 3 and the outer holding piece 15 of the strip holding frame 3. Since it is simply sandwiched between the inner holding pieces 16 and lightly fixed with double-sided tape, the symbol strip 2 can be replaced easily and quickly without the trouble of applying an adhesive.
Also, the pins 1 provided on the strip holding frames 3 and 4 respectively.
Since 3 respectively engages with the holes 8 provided in the symbol strip 2, the symbol strip 2 does not shift from the strip holding frames 3 and 4 during the rotation of the reel 1.

If the distance between the outer holding piece and the inner holding piece of the strip holding frame is formed according to the width of the symbol strip, the double-sided tape or the like need not be used.

[0016]

As described above, according to the reel for slot machine of the present invention, since the symbol strip is locked so as to be sandwiched between the reel frames, the symbol strip is adhered to the reel frame. It doesn't need to be completely fixed with an agent, and as a result, it is easy, reliable, and quick.
The symbol strip can be attached to and detached from the reel frame.
