2. Description of the Related Art Various types of slot machines configured to play games using pachinko balls have been disclosed. In this type of slot machine, a bet switch for a player to select a betting rate, a start switch for rotating a drum on which various symbols are displayed on an outer peripheral surface, and the rotation of the drum are stopped. And a stop switch. The player activates one of the bet switches to select a betting rate, activates the start switch to rotate the drum, and activates each stop switch while measuring the timing.
By doing so, the rotation of each drum is stopped.
In a state where each drum is stopped, a predetermined number of prize balls are paid out when the symbols attached to the outer peripheral surface of the drum are aligned according to a certain rule. Since the timing at which the player activates each stop switch is extremely delicate, it is desirable that the operability of each stop switch be good. The number of the stop switches corresponds to the number of the drums, and is usually three.

However, in the conventional slot machine, the operation of each switch described above is different. For example,
In the slot machine disclosed in JP-A-63-63482, the bet switch and the stop switch have a configuration in which a lever is pressed down, whereas the start switch has a configuration in which a button is pressed. For this reason, the player must change the arrangement position and the arrangement angle of the finger on the game board surface during the game, and it is difficult to quickly operate each switch.

For example, in the slot machine disclosed in Japanese Patent Application Laid-Open No. 57-131469, all switches are push buttons, whereas a stop switch is provided above the upper plate, The start switch and the bet switch are provided below the upper plate portion. For this reason, the player must change the position of the eyes for each game and check the position of each switch, which hinders the concentration of the game.

[0005]

It is exactly the same as in the case.

Pachinko balls R stored in the upper plate 6
The player, by pressing one of the bet button which is also used as the stop button S ₂ to S _4, are taken up by a predetermined number through a constant throwing device B. The constant ball feeding device B will be described. As shown in FIGS. 7 to 9, the device frame 28 constituting the constant ball feeding device B
A stepping motor 29 is attached to a substantially central portion of an upper portion of the motor. An impeller 31 provided with four blades 31a is attached to the motor shaft 29a. One pachinko ball R is taken in between each wing body 31a. On the back side (the side of the stepping motor 29), a flange portion 31b having an outer diameter larger than the outer diameter of the blade body 31a is provided. A U-shaped notch 31c corresponding to each of the blades 31a is provided on an outer peripheral edge of the flange 31b.

A photo sensor 32 is provided obliquely below the impeller 31.
Is installed. The upper end of the photo sensor 32 is bifurcated, and sandwiches the outer peripheral edge of the flange 31b. Light rays are always emitted from one light emitting part 32a toward the other light receiving part 32b. When the stepping motor 29 is operated, the impeller 31 rotates in a predetermined direction. At that time, the light beam of the photo sensor 32 is
It is shut off by the flange portion 31b of the impeller 31. However, the notch 31c of the flange 31b is
When the light passes through the upper end portions of the two (light projecting portion 32a and light receiving portion 32b), light rays are passed. The photo sensor 32 has a function of positioning the impeller 31 at a predetermined position (returning to the origin) when the slot machine A is powered on.

The pachinko ball R in the constant ball feeding device B
Is connected to the throwing slope 6 a of the upper plate 6. In the vicinity of the entrance 33, a supply ball detection switch 34 is provided. This supply ball detection switch 34
Is for detecting the presence of a pachinko ball R (game ball) upstream of the constant ball feeding device B, that is, in the upper plate portion 6, and unless the switch 34 is in the ON state. , The stepping motor 29 is not operated. Also, the pachinko ball R in the constant ball feeding device B
In the vicinity of the outlet 35 of the device,
Are arranged. This take-in number count switch 36
Is pachinko ball R taken from the upper tray 6 by the operation of the constant throwing device B is for counting the number of (game balls), the switch 36 is bet button (stop button S ₂ to S ₄₎ The operation of the stepping motor 29 is stopped at the stage when the number of acquisitions set in the step (1) is detected.

A shutter 37 is provided between the upper plate 6 and the supply ball detection switch 34 to block the inflow of the pachinko ball R sent while rolling on the ball feeding slope 6a. The shutter 37 has a fulcrum shaft 38 supported by a device frame 28 constituting the constant ball feeding device B.
It is rotatable around. At the rear end of the shutter 37, a shutter operation piece 39 (described later) is provided.
When the operation piece 39 is operated, the shutter 3 is moved.
7 rotates downward, and the entrance portion 33 of the pachinko ball R
Is closed. This state is shown by a two-dot chain line in FIG. The pachinko ball R sent from the upper plate 6 is blocked by the shutter 37 at the entrance 33 of the constant ball feeding device B.

As described above, the number of pachinko balls R taken in is counted by the number-of-takes counting switch 36 provided at the outlet 35 of the constant ball feeding device B.
A game is prevented from being played in a state where the switch 36 is illegally turned on by a metal bar or the like. That is, when the number-of-takes counting switch 36 is disposed at the entrance 33 of the constant ball feeding device B, a metal rod or the like is inserted from the upper plate 6 and the switch 36 is turned on illegally, and the pachinko ball R (game ball) Despite the absence of), it is easy to take the initiative to pretend that a ball equivalent to the number of bets has been taken. However, by disposing the number-of-acquisitions count switch 36 at the outlet 35, there is no possibility that the above-mentioned fraud is performed.

Therefore, the supply ball detection switch 34
Detects only the presence or absence of the supplied pachinko sphere R, and does not count the number of intakes. For this reason, the supply ball detection switch 34 may be omitted, but in that case,
Only the bet button (stop button S ₂ to S ₄₎ is pressed condition, the stepping motor 29 even without pachinko ball R supplied to rotate. However, since there is no pachinko ball R, the number-of-acquisitions counting switch 36 cannot count the pachinko ball R, and it is assumed that the stepping motor 29 is kept rotating. In order to prevent this, if the number-of-acquisitions count switch 36 is not turned on for a certain period of time even though the stepping motor 29 is rotating, control such as stopping the rotation of the stepping motor 29 is performed. It is desirable. In the present embodiment, in the state that supply ball detection switch 34 is not turned ON, if the bet button (stop button S ₂ to S ₄₎ is pressed, or after the bet button is pressed, preparative pachinko balls R If the supply ball detection switch 34 is turned off due to running out of the ball during the loading operation, a predetermined error message is displayed.

The operation of the constant ball feeding device B will be described.
The pachinko balls R are taken into the impeller 31a of the impeller 31 one by one from the inlet portion 33 of the constant ball feeding device B. The impeller 31 is always rotated only in one direction by the stepping motor 29. The pachinko ball R taken into each blade body 31a gradually comes off from the portion by its own weight as the impeller 31 rotates, and the pachinko ball collection device provided on the back island stand through the outlet 35. (Not shown).

In FIG. 6, the ball shortage detection plate 41 provided immediately below the storage tank 17 is constantly urged upward by a spring or the like (not shown). When the pachinko ball R in the storage tank 17 runs short, the ball shortage detecting plate 41 rotates upward about the axis of the rotating shaft 42, and the rod 4
3 is moved upward. When the rod 43 moves upward, the lever 44 moves about the axis Q of the rotation shaft 45 as an arrow Q.
Is turned in the direction of. At one end of the lever 44, an engaging member 46 is provided which engages with the above-mentioned shutter operating piece 39, and the shutter operating piece 39 is lifted by the engaging member 46. Then, the shutter 37 is closed, and the pachinko balls R (game balls) stored in the upper plate portion 6 are prevented from entering the constant ball feeding device B.
In a state where the pachinko balls R are sufficiently stored in the storage tank 17 (normal state), the shutter 37 does not close. The shutter 37 is used to prevent the pachinko ball R in the storage tank 17 from running short when the player hits the ball, and to prevent the game from continuing when the prize ball cannot be formed, thereby preventing wasteful consumption of the pachinko ball R. Yes, but not necessary.

The machine body 9 constituting the slot machine A is mounted on a panel 47. Next, Panel 4
7 will be described. The slot machine A of the present embodiment
The panel 47 (that is, the machine body 9) is detachable. The attachment and detachment of the machine main body 9 are performed with the inner frame 2 opened with respect to the outer frame 1 as shown in FIGS. That is, the inner frame 2 is opened, each lock lever 48 (see FIG. 10) is further loosened, and the mechanism plate 16 is opened. This mechanism plate 16
With the panel 47 attached to the panel support frame 8, the panel 47 is closed so as to cover the panel 47 from the rear side, and is fixed to the panel support frame 8 by the lock levers 48. The mechanism plate 16 has a frame shape, and a panel 47 is provided.
The machine body 9 attached to the mechanism plate 16 can protrude rearward (back side) of the mechanism plate 16.

As shown in FIGS. 3, 10 and 11, the panel support frame 8 is provided with an opening 8a slightly larger than the panel 47 on which the machine body 9 is mounted. That is, the dimension in the height direction of the opening 8a is slightly longer than the height of the panel 47, and the dimension in the width direction is slightly longer than the width of the panel 47. At the upper edge of the opening 8a of the panel support frame 8, two panel holding portions 8b projecting downward in an inverted U-shape are provided at two places, and the upper end of the panel 47 is provided in this groove. It is fitted. Therefore, the width of the groove is slightly wider than the thickness of the panel 47. The opening 8 of the panel support frame 8

The hook 49 is rotatable by a fulcrum shaft 51. When the panel 47 is fitted into the opening 8 a of the panel support frame 8, the hook 49 is rotated, and the hook 49 a is hooked on the projection 47 a provided on the panel 47, thereby preventing the panel 47 from coming off. Is played.

A message display section 52 (see FIG. 2) for displaying various messages during a game is provided at the upper portion on the front side of the panel 47. The content of the message only indicates the gaming state of the slot machine A, such as notifying a jackpot based on the game control information or displaying an error of insufficient intake of the pachinko ball R in the constant ball throwing device B described above. Instead, the event information of the game store can be displayed by externally inputting the information from the management computer of the game store. As the form of the message display unit 52, various types of hardware such as a liquid crystal display, a CRT, and a dot matrix display can be considered.

The operation when replacing the machine body 9 will be described. As shown in FIG. 5, the inner frame 2 is opened relative to the outer frame 1, and the lock levers 48 are loosened to open the mechanism plate 16. In this state, the hook 49 is rotated to release the retaining mechanism at the lower end of the panel 47. Subsequently, as shown in FIG. 11, the operator holds the machine main body 9 so as to hold it, and rotates the lower end slightly forward (toward the operator). Panel 4
Since the upper end of 7 is disengaged from the panel holding portion 8b of the panel support frame 8, the machine body 9 is moved downward in the state as it is. By doing so, the machine main body 9 is completely removed from the panel support frame 8.

Next, the operation when the machine main body 9 of the slot machine A of a different model is mounted on the panel support frame 8 will be described. As shown in FIG. 11, the panel 47 to which the machine main body 9 is attached is slightly inclined, and the upper end thereof is fitted into the groove of the panel holding portion 8b. Then, the panel 47 is rotated with the vicinity thereof as a rotation fulcrum, and stops at a state where its lower end portion is abutted against the panel abutting portion 8c. Subsequently, the hook 49 is rotated, and the hook 49 a is hooked on the projection 47 a of the panel 47. A panel 47 to which a different machine body 9 is attached is fixed to the panel support frame 8. In this way, the machine body 9 of the slot machine A is exchanged by changing the panel.

As shown in (5), a message display section 52 may be attached to the front side of the upper portion of the panel support frame 8. in this case,
Since the message display section 52 is fixed to the panel support frame 8, when the machine main body section 9 is replaced by replacing the panel, the message display section 52 up to that time can be used as it is, which is economical. There is. Various control boards (not shown) for controlling the game of the slot machine A may be attached to either the mechanism plate 16 or the panel 47. However, it is preferable that various control boards be mounted on the panel 47 so that they can be replaced at the same time when the panel is replaced.

Further, the size of the glass 11a and the panel 4
If the sizes of the slots 7 are substantially the same, the image of the entire slot machine A can be largely changed by the design of the panel 47 when the panel is changed. However, as described above, when the message display unit 52 is attached to the panel support frame 8, the design around the message display unit 52 does not change even if the panel is changed, and the entire slot machine A is not changed. Changing the image can be difficult. Therefore, as described above, a seal (not shown) on which the design is printed is attached to the glass 11a so that the design of the entire area in which the machine body 9 and the message display 52 are arranged can be changed. ing. Since the glass 11a is replaceable, the image of the entire slot machine A can be changed by a simple operation.

A case where a game is played on the slot machine A will be described. As shown in FIG. 1, when a player presses any of the stop buttons (bet buttons) S _{2 to} S ₄ , a predetermined number of pachinko balls R are stored from the pachinko balls R stored in the upper plate 6, It is taken into the constant ball sending device B. The betting rate selected by the player is displayed by turning on each lamp 19 (see FIG. 2) provided on the game board. Then, when the start button S ₁ is pressed, all of the drum 18 is rotated. For the slot machine A of the present embodiment, each bet button is also used as the stop button S ₂ to S _4. Therefore, one of the bet button is pressed, the subsequently start button S ₁ is pressed, the function of the bet button is configured to switch the function of the stop button S ₂ to S ₄ in the control unit. For this reason, the player sets each of the stop buttons S _{2 to} S ₄
By pressing, the rotation of the corresponding drum 18 is stopped. And each stop button S ₂ to S ₄ is pressed, the rotation of all of the drum 18 is stopped, the function of the stop button S ₂ to S ₄ is switched to the function of the bet buttons in the control unit again. When the symbols pasted on the outer peripheral surface of each drum 18 are aligned under a certain rule, a predetermined number of prize balls are paid out according to the selected betting rate.

In the case of the slot machine A of this embodiment, FIG.
As shown in 3, the start button S ₁ and the stop button S ₂ to S ₄ are on the upper surface of the front side of the upper tray 6, is provided in substantially horizontal state. Then, each of the buttons S _{1 to} S

₄ also serves as a bet button. Therefore, the player, it is possible to reduce the distance to move the finger when pressing the buttons S ₁ to S ₄ in the game. In addition, since all the buttons S _{1 to} S ₄ are provided in substantially the same horizontal plane, the finger placement angle can be made substantially constant when the player operates. As a result, the player is likely to do pressing the stop button S ₂ ~S ₄ is. In addition, since these buttons S _{1 to} S ₄ are provided on the upper surface on the front side of the upper plate portion 6, there is no obstacle behind the buttons S _{1 to} S ₄ , and the operation of the player is not performed. It does not get in the way. As a result of the above, the player does not need to check the position of each button S ₁ to S ₄ in the eye during the game, it is possible to play a game to concentrate only on the game board. In addition, since the arrangement angle of the finger is always in a natural state, the fatigue of the player is reduced.

In the normal case, the player makes the above-mentioned buttons S
For operating the ₁ to S ₄ in the right hand, the buttons S ₁ to S
₄ is preferably provided on the right side from the center in the width direction of the slot machine A when viewed from the front. By doing so, the player can perform all operations with only one hand (in this case, the right hand), and can concentrate more on the game board surface.

Referring to FIG. 14, another embodiment of the slot machine A 'will be described. In the slot machine A 'of this embodiment, the stop button S ₂ to S _4, which also serves as a start button S ₁ and the bet buttons in a row state,
It is provided concentrated on the game board surface above the upper plate 6. In the case of the slot machine A ′, the operation of each of the buttons S _{1 to} S _{4 with} the thumb is facilitated.

Another usage example of the constant ball throwing device B will be described. First, a certain number of credits (usually, 150) of pachinko balls R used in the game are taken in,
It is stored in the control device. When the player presses any of the bet buttons (stop button S ₂ ~S _4), gradually reduced by a predetermined number from the credit amount. This eliminates the need to take in a predetermined number of pachinko balls R each time, thereby increasing the speed of the game.

In this specification, the slot machine in which each switch is a push button has been described. But,
Each switch may be any switch other than a push button, for example, a switch that depresses a lever, a switch that has a built-in touch sensor, and operates with a slight touch, and the like. Further, the buttons S _{1 to} S ₄ may not be provided in a line, but may be provided in a zigzag manner in accordance with the position where the player places his / her finger.
