Description

[Detailed Description of the Invention] The present invention relates to a mounting structure for a sensor board for detecting the stop position of a rotating drum of a slot machine.

Conventionally, this type of sensor board has been fixed directly to the top of the slot machine case with screws.
Therefore, mounting the sensor board was troublesome. In addition, there was the inconvenience of having to spend a lot of time removing and installing the sensor board during repairs.

This invention was made in consideration of the above-mentioned circumstances, and provides a structure in which the above-mentioned sensor board can be mounted very easily.

Hereinafter, with reference to the drawings, the main parts of a slot machine equipped with the sensor board mounting structure of this invention will be explained to clarify the invention.

FIG. 1 is a front view showing an example of a drum device embodying the present invention. FIG. 2 is a schematic perspective view of the drum device shown in FIG. 1.

A shaft 11 is rotatably mounted across a box-shaped case 13 made of plastic. The shaft 11 is located approximately in the middle of the height of the case 13 and is supported via a shaft support plate 25.

A pulley 12 is attached to one end of the shaft 11 protruding from one side surface 13b (see FIG. 2). On the other hand, the drive motor 1
It is attached to the bottom of the motor shaft 5.
A pulley 22 is also attached to the shaft. The pulley 12 and the pulley 22 are interlocked by a belt 23, and when the motor 1 rotates, the shaft 11
It also rotates.

Three rotating drums 6 are rotatably attached to the shaft 11. Generally, the number of rotating drums 6 is three, but the number is not limited thereto. The relationship between the rotating drum 6 and the shaft 11 will be described later.

As described above, the shaft 11 is directly supported by the shaft support plate 25, which is attached to the front flange 13d of the case 13 with screws 24. A shaft support plate 25 engages with notches 28 and 29 (FIG. 3) in the case 13 to support the shaft 11. Each rotating drum 6 has a screw 24
If you remove the shaft 11 and shaft support plate 2
Since it can be pulled forward together with 5, it can be easily removed from the case 13. At that time, it is preferable to remove the pulley 12 from the shaft 11 or shift it to a position where it does not hit the flange 13d.

Figure 3 shows case 1 with shaft 11 removed.
An example of No. 3 is shown. Further, FIG. 4A shows an example of the shaft 11 removed from the case 13.

FIG. 5 is a perspective view showing an example of the shaft support plate 25.

Both ends of the shaft 11 are rotatably installed by a pair of shaft support plates 25 (only one shaft support plate 25 is shown in FIG. 4A). Both shaft support plates 25 are of symmetrical shape. The shaft support plate 25 is also made of plastic. Further, it is preferable that no special bearing be installed between the shaft 11 and the shaft support plate 25, but instead made of relatively hard plastic to constitute an oil-less bearing.

As shown in FIG. 5, the shaft support plate 25 is
It has an L-shape in which the lengths of the two sides 25A and 25B are significantly different, and there is one through hole 26 on the longer side 25A.
is formed, and through holes 20 and 21 for screws 24 are formed in the shorter side 25B. Then, the shaft 11 is passed through the through hole 26. Also, L
A convex portion 27 is formed on the inner surface of the letter shape.
The convex portion 27 is formed along the longitudinal direction of the shaft support plate 25 from the through hole 26 .

On the other hand, as shown in Figure 3, case 1
Notches 28 and 29 are formed in both side surfaces 13b and 13c of 3, respectively. The cutouts 28 and 29 are located approximately in the middle of the height of the case 13. The width B of the notches 28 and 29 is formed to be slightly larger than the width A of the shaft support plate 25, and the convex portion 27 is shaped to fit into the notches 28 and 29 exactly.

In other words, the protrusions 27 of the two shaft support plates 25 attached to both ends of the shaft 11 are connected to the case 13.
The shaft 11 is installed in the case 13 by fitting into the notches 28 and 29.

On the front flange 13d of the case 13, a through hole 30 for the screw 24 is provided with a notch 28,
29 (see FIG. 3).
The through holes 30 are formed above and below each of the notches 28 and 29.

FIG. 6 is a partial view showing the shaft support plate 25 installed in the notch 28.

The shaft support plate 25 is firmly fixed to the flange 13d with screws 24. In the embodiment shown in the figure, since the case 13 is made of plastic, the flange 13d is clamped and tightened with the screws 24 using a backing plate 32 formed with a female thread.

FIG. 7 shows an example of the rotating drum 6 attached to the shaft 11.

The rotating drum 6 is composed of a drum 6a, a boss portion 6b, and a stop plate 6c. A large number of well-known patterns (not shown) are provided on the circumferential surface of the drum portion 6a. A bearing 9 is provided on the boss portion 6b of the rotating drum 6, and the rotating drum 6 can freely rotate relative to the slip rings 14 and 15. The bearing 9 is preferably a plastic flat bearing (referred to as a dry bearing or oil bearing) that does not require oil injection.

The stop plunger 3 is for stopping the rotating drum 6.

A pair of slip rings 14 and 15 are provided on both sides of the rotating drum 6. Bearing 9
and the sliding portion 14c of the slip rings 14 and 15.
and 15c are engaged with each other, and the rotating drum 6 is rotatably installed on the shaft 11.

FIG. 8 is a perspective view showing an example of the slip ring 14.

Slip rings 14 and 15 are symmetrical. The slip ring 14 is composed of a boss portion 14a, a flange portion 14b, and a cylindrical sliding portion 14c, and has a shaft hole 14d in the center.
Further, a notch 40 is formed in the boss portion 14a in the axial direction.

The slip ring 14 (see FIG. 7) is always pushed toward the boss portion 6b of the rotating drum 6 by the spring 7. On the other hand, slip ring 15
is prevented from moving by a retaining ring 38. Therefore, the rotating drum 6 rotates together with the slip rings 14 and 15 due to the frictional force. That is, as shown in FIG. 1, since the slip rings 14, 16, and 17 are pushed by the biasing force of the spring 7, a frictional force is generated between them and the rotating drum 6. is shaft 11
rotates with

FIG. 9 is a diagram showing the relationship among the slip ring 14, shaft 11, and pin 8.

Slip ring 14 is attached to shaft 11 by pin 8. On shaft 11,
Through holes 39 are opened at predetermined positions corresponding to the number of slip rings (six in the illustrated example). On the other hand, a notch 40 is formed in the boss portion 14a of the slip ring 14. The through hole 39 and the notch 40 are aligned, the pin 8 is inserted, and the slip ring 14 is installed on the shaft 11. Therefore, the slip ring 14 always rotates together with the shaft 11, and the rotating drum 6 also rotates due to frictional force.

However, when the rotating drum 6 is stopped by the stop plunger 3, the boss portion 6b of the rotating drum 6 and the slip rings 14 and 15 slide, and the slip rings 14 and 15 rotate idly. At this time, the slip ring 14 has room to move back and forth due to the spring 7 and the notch 40, so it is easy to rotate idly.

The fit between shaft 11 and slip rings 14 and 15 does not require high mechanical precision. It does not matter as long as the slip rings 14 and 15 can move freely.

FIG. 10 shows an example of the stop plunger 3, the stop arm 4, and the stop plate 6c.

Stop plunger 3 and stop arm 4
is installed in the plunger case 33. In other words, the plunger 3, stop arm 4, etc. are assembled into a unit into the plunger case 33.

As the plunger 3, a bistable plunger or a monostable plunger is used.

The shaft of a bistable plunger has two states: retracted and extended. Furthermore, the shaft of the monostable plunger has a retracted state, a protruded state, and a free state. Both bistable plungers and monostable plungers need only be energized when moving the shaft from one state to another, and do not need to be energized when holding the shaft in one state.

By passing a pulsed current through terminals C and D of the plunger 3, the plunger shaft 34 moves up and down. One end of the stop arm 4 is rotatably connected to the tip of the plunger shaft 34. The other end of the stop arm 4 is bent at approximately 90 degrees so that the tip 35 engages with the stop plate 6c. The stop plate 6c is fixed to the rotating drum 6, and the drum portion 6a of the rotating drum 6 and the stop plate 6c rotate together.

The stop arm 4 is rotatably installed on the plunger case 33 at a fulcrum 36. Therefore, when the shaft 34 of the stop plunger 3 moves downward, the claw portion 35 at the tip of the stop arm 4 engages with the stop plate 6c, and when it moves upward, it separates from the stop plate 6c.

If the stopping plunger 3 is a monostable plunger, a retaining spring 37 is attached to the plunger shaft 34. When the plunger shaft 34 is in a free state, the holding spring 37 moves the plunger shaft 34 upward or downward and maintains this state.

A cushioning material 10 such as an elastic material such as rubber is provided on the plunger case 33 in order to prevent impact from being applied to the plunger case 33 when the stop arm 4 is released from the stop plate 6c and lowered. The cushioning material 10 is made of an elastic material such as rubber, and is provided on the plunger case 33 at a portion where the stop arm 4 comes into contact.

As clearly shown in FIG. 10, the plunger case 33 has a bottom surface 33a that is grounded to the top surface of the case 13, a rear portion 33b that is regulated by a stepped portion 13e of the case 13, and a front portion 33c.
is locked by a locking member 70. This locking member 70 is fixed to the case 13 at both ends with screws 72. Also, plunger case 3
The bottom surface 33a of the case 1 is guided by an L-shaped guide 73 as clearly shown in FIG.
It is possible to take it in and out by sliding it in the front and rear directions of 3. That is, with the locking member 70 removed, the plunger 33 is inserted deep along the guide 3, and when the rear part 33b of the bottom surface 33a of the plunger case 33 touches the stepped part 13e of the case 13, the locking member 70 to case 13 with screw 72
This locks the plunger case 33. To remove it, just follow the steps in reverse.

Next, the rotating drum 6 will be explained.

As can be seen in FIG. 4A, a large number of through holes 2 are formed radially in the side surface 46 of the drum portion 6a of the rotating drum 6. The shape of the through hole 2 may be rectangular or circular.

FIG. 4B shows an example of the side surface 46 of the drum portion 6a. In FIG. 4B, the stop plate 6c
It is shown with it removed.

The arrangement of the through holes 2 formed on one radial line is unique to one figure drawn on the pattern section 6a' on the outer periphery of the drum section 6a. Therefore,
For example, if 20 figures are drawn on the picture area 6a', 20 rows of through holes 2 are required to be arranged radially. That is, the side surface 46 is divided into 10 parts by diameter, and the through holes 2 unique to each shape are arranged on each radius.

The arrangement of the through holes 2 is unique to the figure on the pattern portion 6a', so if the arrangement of the through holes 2 is detected at a certain point when the rotating drum 6 stops, it is possible to determine which figure the rotating drum 6 is in. You can tell if it has stopped at a point.

FIG. 4C is an explanatory diagram of detecting the arrangement of the through holes 2.

The arrangement is detected using the lamp 44 and the light receiving elements 47 to 52.
made by. The number of light receiving elements is 6 in the picture area.
Determined by the number of shapes on a′. For example, if there are 20 figures in total, a maximum of five through holes 2 may be opened on one radius. because,
2 (=
32) Possible combinations. Therefore, in this case, five light receiving elements are required. The number of lamps 44 may be one or more as long as sufficient brightness is obtained. In the illustrated example, the lamp 44
Two pieces were used.

The lamp 44 and the light receiving elements 47 to 52 face each other with the rotating drum 6 in between. Light receiving element 47
52 are installed in a line on the sensor board 42 (see FIG. 1). The sensor board 42 is fixed to the case 13 so that the light receiving elements 47 to 52 are located on the radius of the rotating drum 6. The through hole 2 is opened so as to be located above any one of the light receiving elements 47 to 52. Then, when the rotating drum 6 stops, the arrangement of the through holes 2 can be determined depending on which light receiving element senses the light, and the stopping position of the rotating drum 6 can be detected. For example, in FIG. 4C, the light receiving element 4
7 and 49 are sensing light. Light receiving elements 47 and 4
Since there is no other arrangement of through holes 2 such that 9 detects light, it is possible to specify at which figure the rotating drum 6 has stopped.

Further, one of the light receiving elements 47 to 52 can also be used to check the stop position of the rotating drum 6.

In other words, the figure drawn on the picture part 6a' must stop correctly in a window (not shown) formed in the front panel of the slot machine. but,
It is also possible that the pattern on the rotating drum 6 does not stop at the correct position due to some kind of trouble. For checking in such a case, one of the light receiving elements 47 to 52 is used.

That is, for example, the through hole 2 corresponding to the light receiving element 47 is always opened (in FIG. 4c, the through hole closest to the periphery of the rotating drum 6), and it is determined at which figure the rotating drum 6 stops. Also, the light receiving element 47 should be sure to sense it. By doing so, if the light receiving element 47 does not detect light, it can be determined that the rotating drum 6 is not stopped at the correct position.

Sensing signals from the light receiving elements 47 to 52 are sent to a socket 53 (FIGS. 1 and 3) installed on the sensor board 42.
(see figure) to a central control unit (not shown). The central control unit determines the number of spins to be paid out as a reward based on the sent sensing signals.

The sensor board 42 and the lamp 45 are installed on the middle plate 63 (see FIG. 1). Middle plate 63 is case 1
It extends vertically downward from the upper surface 13a of 3. Also,
A panel 66 is attached to the flange 13d to prevent unnecessary light from entering the light receiving elements 47-52.

FIG. 11 is a perspective view showing an example of the middle plate 63.

The size of the middle plate 63 is determined by the sensor board 42. The lower end of the middle plate 63 is bent into a key shape,
A guide 54 and a groove 55 are formed there. Then, the sensor board 42 is inserted into the groove 55 and installed. The guide 54 is provided to ensure that the sensor board 42 fits properly into the groove 55 when it is inserted.

The upper surface 13a is widely cut out around the upper end of the middle plate 63 to form the outlet 43. The sensor board 42 is taken in and taken out through the outlet 43. However, normally, a cover 56 is provided on the outlet 43.
is installed (see Figure 2).

Figure 12 shows the cover 5 that can be installed in a one-touch manner.
FIG. 6 is a perspective view showing an example of FIG.

Also on the lower surface 56a of the cover 56, the guide 5
7 is formed, and when the cover 56 is attached to the opening 43, the upper end of the sensor board 42 is aligned with the groove 5.
It is designed to fit in at 8. Therefore, cover 5
6, the sensor board 42 can be securely fixed without any other fixing means.

A hole 59 is formed in the center of the cover 56, and the socket 53 of the sensor board 42 protrudes from the hole 59 when the cover 56 is attached to the outlet 3. A signal line for sending signals to a central control unit (not shown) is connected to the socket 53.

The cover 56 is attached using two L-shaped locking portions 60 provided at the rear end of the cover 56 and one hook 61 provided at the front end. The number of locking portions 60 and hooks 61 may be one or more.

First, the locking portion 60 is engaged with the rear edge 43b of the opening 43, and then the hook 61 is engaged with the front edge 43a to perform attachment. Hook 61 has a thin wall thickness,
It is highly elastic, so it can be easily installed.

The lamp 45 is installed on the surface of the sensor board 42 opposite to the image on which it is installed. Therefore, the light receiving elements 47 to 52 of the sensor board 42 are
It does not receive light from the lamp 45 installed on the same middle plate 63. As shown in FIG.
Receives light from 4. Therefore, the light receiving element installed on the middle plate 62 on the side surface 13c receives light from the lamp 65 installed on the side surface 13c. Further, there is no need to install a lamp on the middle plate 64 on the side surface 13b side.

As explained above, with this invention, the sensor board can be installed in the specified position by simply inserting it through the outlet at the top of the case, and all that is left to do is fixing the cover with one touch, making repairs extremely quick. And it has the effect of being able to be implemented accurately.
