Hereinafter, a pachinko machine according to an embodiment to which the present invention is applied will be described.
First, FIG. 1 is a front view showing the front surface of the pachinko machine 2 of the present embodiment. In FIG. 1, 4 is a front frame of the pachinko machine 2, 6 is a game board mounted behind the front frame 4, and 8 is an edge frame mounted on the inner periphery of the transparent window of the front frame 4. Reference numeral 10 denotes a glass door that is attached to the edge frame 8 so as to be able to be opened in one direction and covers the surface of the game board 6 (that is, the game surface).
[0015]
In FIG. 1, 12 is a guide rail provided on the game surface of the game board 6 to form a game area, and 14 stores pachinko balls that are launched into the game area via the guide rail 12. An upper plate (a hitting ball supply tray) from which a prize ball corresponding to a prize is discharged is discharged from the upper plate 14 when a ball passage (not shown) formed in the upper plate 14 is opened. A lower dish that receives pachinko balls.
[0016]
And in the pachinko machine 2 of a present Example, the piezoelectric actuators 18L and 18R for generating the various sound effects according to a game state are attached to the glass door 10 right and left.
Then, next, the structure of the glass door 10 is demonstrated using FIG.2 and FIG.3. FIG. 2 is an explanatory view for explaining the structure of the glass door 10, and (B) shows a cross section in the XX direction in (A). FIG. 3 is an enlarged view of a portion Q surrounded by a two-dot chain line in FIG.
[0017]
As shown in FIGS. 2 and 3, the glass door 10 is attached to four side edges of the two glass plates 20a and 20b and the glass plates 20a and 20b, respectively, so that the glass plates 20a and 20b are spaced at a predetermined interval. The four frame members 22a, 22b, 22c, and 22d to be held are configured.
[0018]
Each of the frame members 22a to 22d is formed in a long shape with a resin such as hard polyurethane, and has two grooves along the longitudinal direction on the inner side surface (the surface attached to the glass plates 20a and 20b). 24a and 24b are provided in parallel. Therefore, the cross sections of the frame members 22a to 22d have an “E” shape.
[0019]
Moreover, the edge part of each frame material 22a-22d has an angle of 45 degree | times with respect to a longitudinal direction so that a square holding frame can be formed combining each other at right angles. Further, among the frame members 22a to 22d, the frame members 22a, 22b, and 22c attached to the left side edge, the lower side edge, and the right side edge of the glass plates 20a and 20b, respectively, have piezoelectric actuators 18L and 18R. Wiring holes are formed for wiring the extended signal lines 26L and 26R as indicated by dotted lines in FIG.
[0020]
And the glass door 10 is assembled in the following procedures.
First, the three frame members 22a, 22b, and 22c are combined at right angles to form a “U” shape. In this state, the signal lines 26L and 26R extending from the piezoelectric actuators 18L and 18R are inserted into the wiring holes of the frame members 22a, 22b and 22c as shown by dotted lines in FIG. Is taken out from the vicinity of the left end of the frame member 22b. After that, the ends of the frame members 22a, 22b, and 22c are bonded and fixed with an adhesive to form a “U” -shaped frame (hereinafter referred to as a U-shaped frame).
[0021]
Next, after attaching the piezoelectric actuators 18L and 18R between the two glass plates 20a and 20b as described later, the glass plates 20a and 20b are attached to the grooves 24a and 24b of the U-shaped frame made of the frame members 22a to 22c. Fit in each. At this time, the ends of the signal lines 26L and 26R taken out from the U-shaped frame (frame member 22b) are pulled to eliminate the bending of the signal lines 26L and 26R.
[0022]
Finally, the frame member 22d is attached so that the upper edges of the glass plates 20a and 20b fit into the grooves 24a and 24b, and both ends of the frame member 22d and the ends of the frame members 22a and 22c are bonded with an adhesive. By doing so, the glass door 10 is completed.
In this completed state, the glass plates 20a and 20b are firmly held without any play by the grooves 24a and 24b formed in the four frame members 22a to 22d constituting the holding frame. Note that an adhesive may be applied to the grooves 24a and 24b of the frame members 22a to 22d so that the glass plates 20a and 20b and the frame members 22a to 22d are completely bonded.
[0023]
On the other hand, as shown in FIG. 2, the signal lines 26L and 26R taken out from the glass door 10 (frame member 22b) are connected to a driver circuit 29 that drives the piezoelectric actuators 18L and 18R in accordance with an acoustic signal from the control device 28. Connected.
The control device 28 displays various images on a liquid crystal display device (not shown) provided on the game surface of the game board 6 according to the winning state of the pachinko machine 2, and when a predetermined condition is satisfied. Then, an electric winning device (not shown) provided on the game surface is driven to perform control such that the pachinko machine 2 is in a big hit state having a higher winning probability than usual. Then, the control device 28 outputs to the driver circuit 29 an acoustic signal for generating a sound effect corresponding to the gaming state or an image displayed on the liquid crystal display device. Further, the control circuit 28 and the driver circuit 29 are provided at predetermined positions in the pachinko machine 2.
[0024]
Next, the piezoelectric actuators 18L and 18R will be described.
As shown in FIG. 4, each of the piezoelectric actuators 18L and 18R is formed by laminating a large number of piezoelectric elements (piezoelectric ceramics) 30 made of lead zirconate titanate (PZT) or the like via internal electrodes 32, and the laminated piezoelectric elements. It has a known structure in which a pair of external electrodes 34p and 34m are attached to both sides of 30. In FIG. 4, 35 is an insulator.
[0025]
Of the two lead wires 36p, 36m constituting the signal lines 26L, 26R, the positive lead wire 36p is connected to the external electrode 34p, and the signal line 26L, Of the two lead wires 36p and 36m constituting 26R, the negative lead wire 36m is connected.
[0026]
The piezoelectric actuators 18L and 18R extend in the direction of the arrow in FIG. 4 when a voltage is applied to the external electrodes 34p and 34m via the signal lines 26L and 26R (lead wires 36p and 36m). Therefore, by changing the voltage applied to the external electrodes 34p and 34m, it can be expanded and contracted in the direction of the arrow in FIG.
[0027]
Then, as shown in FIG. 4, each piezoelectric actuator 18L, 18R has two sheets so that the surfaces (upper surface and lower surface in FIG. 4) whose distances change due to the expansion and contraction abut against the glass plates 20a, 20b. It arrange | positions between glass plate 20a, 20b, and the contact surface is adhere | attached on glass plate 20a, 20b with the adhesive agent 38. FIG. Further, as shown in FIGS. 1 and 2, the piezoelectric actuators 18L and 18R are arranged on the left and right sides of the glass plates 20a and 20b, respectively.
[0028]
Next, a driver circuit 29 for driving such piezoelectric actuators 18L and 18R will be described.
As shown in FIG. 5, the driver circuit 29 amplifies the left acoustic signal LS output from the control device 28 to a voltage level that can drive the piezoelectric actuators 18L and 18R, and the amplified signal is output to the signal line 26L. The left side amplification circuit 40L output to the plus side lead wire 36p and the right side acoustic signal RS output from the control device 28 are amplified to a voltage level capable of driving the piezoelectric actuators 18L and 18R, and the amplified signal is signal line And a right amplifier circuit 40R that outputs to the positive lead wire 36p of 26R. The negative lead wires 36m of the signal lines 26L and 26R are both connected to the reference potential (0 V).
[0029]
Therefore, the left acoustic signal LS from the control device 28 is amplified between the external electrodes 34p and 34m of the piezoelectric actuator 18L attached to the left side by the glass door 10 via the lead wires 36p and 36m of the signal line 26L. Similarly, the control device 28 is connected between the external electrodes 34p and 34m of the piezoelectric actuator 18R attached to the right side of the glass door 10 via the lead wires 36p and 36m of the signal line 26R. A voltage obtained by amplifying the right acoustic signal RS from is applied.
[0030]
In the pachinko machine 2 of the present embodiment configured as described above, when the control device 28 outputs the acoustic signals LS and RS corresponding to the game state and the display image on the liquid crystal display device, the piezoelectric actuators 18L and 18R. However, it expands and contracts according to the corresponding acoustic signals LS and RS, and the mutual distance between the glass plates 20a and 20b is changed with the expansion and contraction. As a result, as shown by the alternate long and short dash line in FIG. 2, the glass plates 20a and 20b vibrate using the piezoelectric actuators 18L and 18R as vibration sources, and this vibration causes the glass plate 20a to the outside (player side). Sound effects corresponding to the acoustic signals LS and RS are generated. Although sound is also emitted from the rear glass plate 20b, the sound is difficult to leak to the outside, so that the sound emitted from the front glass plate 20a is emitted to the outside of the pachinko machine 2.
[0031]
That is, in the pachinko machine 2 according to the present embodiment, the speaker is not provided with a predetermined position as in the conventional pachinko machine to generate sound, but the glass plates 20a and 20b covering the game surface are vibrated to generate sound. .
Therefore, according to the pachinko machine 2 of the present embodiment, since the sound comes to be heard from the game surface where the pachinko game is developed, the visual position sense when the player plays the game and the auditory sense It is possible to match the sense of position. Therefore, the fun of pachinko games can be provided without giving the player a sense of incongruity.
[0032]
Moreover, according to the pachinko machine 2 of the present embodiment, since the sound is generated from the glass plate 20a close to the player's ear, it is not necessary to increase the volume unnecessarily.
By the way, when an actuator is attached only to the outer glass plate 20a, or when there is only one glass plate, the following may be performed. That is, in this case, an actuator having a fixed portion fixed to the glass plate and a vibrating portion that vibrates in response to an external signal with respect to the fixed portion is used. What is necessary is just to vibrate a glass plate with the reaction force at the time of vibrating.
[0033]
However, in this case, the weight of the vibration part must be set to be somewhat large, and there is a limit to raising the vibration frequency or changing the vibration frequency abruptly.
On the other hand, in the pachinko machine 2 of the present embodiment, a piezoelectric actuator that can expand and contract in a direction perpendicular to the surface between the two glass plates 20a and 20b held at predetermined intervals by the frame members 22a to 22b. Glass plates 20a and 20b are vibrated by attaching 18L and 18R and expanding and contracting the piezoelectric actuators 18L and 18R.
[0034]
Therefore, according to the pachinko machine 2 of the present embodiment, the front glass plate 20a can be reliably vibrated with a simple configuration to generate sound.
Further, according to the pachinko machine 2 of the present embodiment, the piezoelectric actuators 18L and 18R are attached between the two glass plates 20a and 20b, so that the piezoelectric actuators 18L and 18R are touched from the outside by a player or the like. On the contrary, the piezoelectric actuators 18L and 18R do not get in the way of pachinko balls that fly to the game surface.
[0035]
In the pachinko machine 2 of the above embodiment, the glass plates 20a and 20b are vibrated using the piezoelectric actuators 18L and 18R. However, the glass plates 20a and 20b are vibrated using an electromagnetic actuator that expands and contracts by electromagnetic force. You may do it. However, since the piezoelectric actuators 18L and 18R are excellent in response speed, control accuracy, and generated stress, it is possible to generate more faithful sounds with respect to the acoustic signals LS and RS from the control device 28. This is advantageous.
[0036]
On the other hand, in order to further enhance the effect of the pachinko machine 2, for example, as shown in FIG. 6, a body sonic that vibrates in cooperation with the piezoelectric actuators 18L and 18R is attached to a chair 50 on which a player sits. Combined with the sound from the glass plate 20a of the pachinko machine 2, an excellent acoustic effect can be obtained.
[0037]
Further, as shown in FIG. 6, rear speakers 52L and 52R are arranged on the floor of the pachinko hall on the left and right rear sides of the chair 50, respectively, and the glass plate 20a (piezoelectric actuators 18L and 18R) of the pachinko machine 2 is arranged. A surround sound field may be formed in cooperation.
[0038]
In addition, as shown in FIG. 7, when there are a plurality of pachinko islands 60 configured by arranging the pachinko machines 2 of the above embodiment back to back, for example, the pachinko machine 2 in which the number in the circle is “1”. When the slanted pachinko machine 2 is in a big hit state, the glass plate 20a of each pachinko machine 2 is sounded in the order of numbers in circles (1, 2, 3, 4,...) If controlled to the above, it is possible to realize an acoustic effect in which the sound moves in a spiral shape around the pachinko hall 2 around the pachinko machine 2 in a big hit state.
[0039]
And when performing the acoustic control of the whole pachinko hall in this way, the pachinko machine 2 that produces sound centering on the pachinko machine 2 in a big hit state may be changed radially, or simply The pachinko machine 2 that generates sound may be sequentially changed from the pachinko machine 2 in the big hit state to the adjacent pachinko machine 2.
[0040]
Further, when the pachinko machine 2 that generates sound is sequentially changed as described above, a jackpot notification lamp or the like provided on the upper part of the pachinko machine 2 that emits sound is lit in cooperation with the sound. May be. And if it does in this way, when any pachinko machine 2 becomes a big hit state, sound and light will move in the pachinko hall, and the player's willingness to play can be further improved. .
