Description

  The present invention relates to a speaker unit and a gaming machine, and more particularly to a speaker unit or the like that can detect an abnormal operation of a speaker and prevent an illegal act.

  In a pachinko machine, a ball that has been shot down flows down a game area (an area formed on or near the game board surface for realizing a game or production by the flow of the ball). During the flow-down process, the ball rolls while colliding with a gauge (also called an obstruction nail) or impeller in the game area, and the flow-down direction changes. As a result, if a ball wins a prize at various winning holes arranged in the game area, a ball as a predetermined prize is paid out, while if a ball flows into the outlet without winning a prize, Balls are not paid out. The player enjoys the game by demonstrating his / her skill in the ball or using the contingency in the flow of the ball and expecting to win the ball and pay out the prize.

  Various decoration members are also attached to the pachinko machine, making the game production even more effective. For example, on the front side of the pachinko machine and on the game board surface, a wide variety of electrical decorations (light bulbs, LEDs, etc.) and movable objects are arranged, which can be operated in various ways according to the game situation, and can be lit or flashed. is doing. In addition, a speaker is also arranged on the front side of the pachinko machine, and various voices (including sound effects and music) are generated according to the game situation, and voice production is performed to excite the game.

  Conventionally, in this pachinko machine, illegal acts by players have been a problem. For example, foreign matter such as a piano wire is made to enter the inside through a gap in the housing frame to damage internal parts and equipment, or illegally obtain a sphere as a prize. In addition, illegally generating magnetic fields and radio waves to adversely affect the sensors and electronic devices inside the pachinko machine and obtain a large amount of spheres as prizes.

  In order to prevent these illegal acts, the pachinko machine is provided with various fraud detection means. For example, Patent Document 1 discloses a technique for detecting fraud performed using a magnet or a radio wave transmitter.

JP 2002-273017 A

  When such a fraud detection means detects a fraudulent act of a fraudster, the speaker emits a warning sound and is notified to nearby players and hall personnel in the gaming machine hall. The generation of warning sound from a speaker enables early detection of fraud, and in turn prevents fraud. In recent years, however, the speaker has been destroyed in advance to make it impossible to generate a warning sound, and fraudulent acts are carried out to prevent the frauds from being discovered, or the discovery of fraudulent acts can be delayed. It is possible to gain illegally.

  That is, the act of destroying a speaker in a gaming machine can be said to be an action that is performed as a preparation stage for fraud, although the act itself does not directly lead to illegal acquisition of prizes.

  The present invention has been made in view of the above circumstances, and a speaker unit capable of early detection and prevention of fraudulent activity by detecting that a speaker capable of performing fraud is destroyed. It is an exemplary problem to provide a gaming machine.

  In order to solve the above-described problems, a speaker unit as an exemplary aspect of the present invention is a speaker unit that is arranged in a gaming machine capable of playing with a game medium and performs sound production, and is based on energization When it is determined that the operation of the speaker is normal by determining whether the speaker is normal or not based on the detection result of the speaker that performs the sound production by the sound generation operation, the detection unit that detects the operation of the speaker, and the detection unit A control unit that transmits a notification signal.

  Since it is possible to detect an abnormal operation of the speaker and transmit a notification signal, it is possible to make a hall member or the like know early that the speaker is abnormal in operation. Therefore, even if the speaker is destroyed, it is possible to prevent the fraudulent act from happening by having the hall member or the like grasp it early. Here, the abnormal operation of the speaker means a state where sufficient sound cannot be generated from the speaker. For example, the speaker diaphragm is broken or the wiring cable to the speaker is broken. It is done. The destruction of the speaker is performed by breaking the diaphragm of the speaker or cutting the wiring cable to the speaker so as to impair the voice production function of the speaker. Thus, the destruction of the speaker can be grasped.

  Also, the abnormal operation of the speaker can be caused not only by destruction but also by failure. By notifying the abnormal operation of the speaker, it becomes possible to quickly grasp and quickly recover from the failure of the speaker. Therefore, when an illegal act is performed on the gaming machine, it is possible to prevent a problem that the voice notification cannot be performed because the speaker is broken.

  For example, if the detector cannot detect current from the power transmission line to the speaker when the speaker is energized, cannot detect sound generated from the speaker, or cannot detect vibration of the speaker diaphragm, By detecting it, it is possible to quickly grasp the above-mentioned destruction or failure of the speaker.

  The control unit may transmit a notification signal to the outside of the gaming machine. Since the notification signal is transmitted to the outside of the gaming machine, abnormal operation of the speaker can be notified to the outside of the gaming machine. For example, if a warning light is provided on an island facility where a plurality of gaming machines are arranged, and a warning signal is sent to the warning light to light it up, the hall member will be notified of abnormal operation of the speaker by the warning light. Can be made. Further, if a notification signal is transmitted to a hall computer that centrally manages the entire gaming machine hall, abnormal operation of speakers in a plurality of gaming machines can be collectively managed. If an abnormality notification is made on the hall computer display or the like when the notification signal is received, it is possible to reliably grasp the abnormal operation of the speakers in a plurality of gaming machines at one place.

  A gaming machine according to another exemplary aspect of the present invention includes a gaming device body that produces a game using a gaming medium, a frame body that houses the gaming device body so that the gaming area can be visually recognized, and a gaming device body. And a front transparent plate arranged at a certain distance or more and the speaker unit.

  Since the gaming machine has a speaker unit that can detect an abnormal operation of the speaker and transmit a notification signal, the gaming machine can notify the abnormal operation of the speaker due to a breakdown or a failure, and allow a hall member or the like to grasp it early. . Therefore, it is possible to prevent fraud by prematurely grasping the destruction of the speaker. In addition, it is also possible to prevent problems such as the inability to perform voice notification because the speaker is broken when an illegal act is performed by early grasping and early restoration of the failure of the speaker.

  You may further have an image display part which is arrange | positioned at a game area and displays the alerting | reporting image for alert | reporting abnormality based on an alerting | reporting signal.

  Since the notification image can be displayed on the image display unit, it is possible to visually notify the player of the abnormal operation of the speaker. For example, when a player destroys a speaker, if a message such as “Anomaly has occurred” is displayed on the image display unit as a notification image, for example, it is possible to make it difficult to perform a subsequent fraud. Can be prevented.

  In recent years, in particular, a gaming device body is provided with a relatively large image display unit from the standpoint of improving interest, and if a notification image is displayed on the image display unit, a game machine can play the game machine. As a result, not only the player who plays the game but also the nearby players and hall personnel can be made aware of the abnormal operation of the speaker, and the deterrent effect can be further enhanced.

  A payout device that pays out the game medium when a predetermined condition is satisfied, and a payout control unit that prohibits payout of the game medium by the payout device when the notification signal is acquired may be further included.

  Since the payout device is prohibited from paying out game media, even if the speaker is destroyed as a preparation for fraud, it is possible to prevent the illegal gain of game media as a prize by subsequent fraud be able to.

  You may further have the launch unit which launches a game medium toward the upper part of a game device body, and the launch control part which prohibits launch of the game medium by a launch unit, when a notification signal is acquired.

  Since the launch of the game medium by the launch unit is prohibited, it is possible to make it impossible to continue the game when the speaker is destroyed as a preparation for fraud. Therefore, after the speaker is destroyed, for example, even if a prize opening provided on the gaming apparatus body is operated so that the gaming medium is easily won by an illegal act, the gaming medium cannot be launched. It is possible to prevent the game media from being illegally acquired by winning the game media.

  Further objects and other features of the present invention will become apparent from the preferred embodiments described below with reference to the accompanying drawings.

  According to the present invention, by transmitting a notification signal when an abnormal operation of a speaker provided in a gaming machine is detected, the destruction of the speaker or the failure of the speaker, which is performed as a preparatory stage for fraudulent acts, The hall members of the gaming machine hall can be grasped at an early stage, and early detection and prevention of fraudulent acts performed thereafter can be achieved.

The slit 21d is formed to efficiently transmit the sound generated from the speaker 21b toward the front of the pachinko machine 2. The sound generated from the speaker 21b is transmitted forward through the slit 21d without being disturbed by the speaker grille 21a.

  The speaker 21b is used for sound production by generating music, sound effects, etc. according to the game situation of the pachinko machine 2, and for transmitting information by generating various warning sounds, message sounds, etc. . The speaker 21b has a voice coil 21e and a diaphragm 21f. The vibration generated when the voice coil 21e is energized is propagated in the air by the diaphragm 21f to generate sound.

  The wiring 21c is connected to the voice coil 21e and is used to energize the voice coil 21e with the current transmitted from the power transmission unit 23c. Among the players who play with the pachinko machine 2, there are those who try to perform illegal acts using the magnetism or radio waves, or illegal acts that cause foreign objects to enter the pachinko machine 2. Such a player may destroy the speaker 21b in order to prevent unauthorized notification by the speaker 21b. For example, the wiring 21c may be cut in order to disable the sound generation operation by the speaker 21b.

  For example, a foreign object is inserted through the gap of the slit 21d formed in the speaker grille 21a, pierces the diaphragm 21f, and cuts the wiring 21c connected to the voice coil 21e.

  The current detection unit 23a detects a current transmitted from a power transmission unit 23c, which will be described later, toward the voice coil 21e, and detects the operation of the speaker 21b.

  The control device 23b has a function as a voice control unit that causes the power transmission unit 23c to perform power transmission toward the voice coil 21e so that the speaker 21b performs voice presentation in accordance with the game situation. The control device 23b also has a function of determining whether or not the operation of the speaker is normal. Specifically, the control device 23b determines that the wiring 21c is disconnected (speaker 21b) when the detection signal cannot be received even though power transmission from the power transmission unit 23c to the voice coil 21e is performed. It is determined that the operation is abnormal. The control device 23b has a function of transmitting a notification signal toward the image control board 33 when it is determined that the wiring 21c is disconnected.

  As described above, the transmission of the notification signal causes the liquid crystal display unit 34a of the image display device 34 to display “abnormal occurrence”, so that an abnormality such as the disconnection of the wiring 21c is reported to nearby players and hall personnel. Can be notified. Although the destruction of the speaker 21b itself does not directly lead to the illegal acquisition of the prize sphere, it is highly probable that an illegal act will be performed after that, so that the illegal operation is prevented by notifying the abnormality when the wiring 21c is disconnected. Can do.

  In the first embodiment, the control device and the power transmission unit are configured separately. However, these functions may be configured to be exhibited by one device.

  Further, the transmission destination of the notification signal by the control device 23b can be variously considered in addition to the image control board 33. For example, the notification signal may be transmitted to the payout control board. When the payout control board receives the notification signal, if the ball is not paid out by the prize ball payout device, even if the winning hole 26, 28, 30 is illegally awarded a ball after the wire 21c is disconnected, the ball It is possible to prevent fraudsters from gaining profits (obtaining spheres as prizes) without being paid out.

  Furthermore, you may comprise so that a notification signal may be transmitted toward a launch control board. When the launch control board receives the notification signal, if the launch unit is configured to prohibit launching of the ball, even if the winning prize opening 30 is illegally opened after the wiring 21c is disconnected, the launch of the ball is not performed. It is possible to prevent the payout of the ball by preventing winning from the winning opening. That is, it is possible to prevent a fraudster from gaining profits (acquiring a ball as a prize).

  Further, the notification signal may be transmitted to the outside of the pachinko machine 2. For example, in a gaming machine hall where a plurality of pachinko machines 2 are installed, if a notification signal is transmitted toward a hall computer (not shown) that centrally manages the entire gaming machine hall, the speakers 21b in the plurality of pachinko machines 2 Can be managed collectively. If it is configured such that when a notification signal is received, a display (not shown) of the hall computer is displayed so as to be able to grasp which speaker 21b of the pachinko machine 2 is operating abnormally, a plurality of The abnormal operation of the speaker 21b in the pachinko machine 2 can be reliably grasped at one place on the display of the hall computer.

  Further, a warning signal 52 can be transmitted to the warning lamp 52 provided in the island facility 50 (see also FIG. 3) in which a plurality of pachinko machines 2 are arranged, and the warning lamp 52 can be turned on. . By turning on the warning lamp 52, it is possible to notify the abnormal operation of the speaker 21b and to enable the hall personnel of the gaming machine hall to grasp the abnormal operation of the speaker 21b at an early stage. That is, the warning lamp 52 exhibits a function as a notification unit that notifies an abnormal operation of the speaker 21b.

  In addition, a notification signal can be transmitted to the calling lamp 54 provided in the island facility 50 to turn on the calling lamp 54. The call lamp 54 is provided for each placement space 50a in which the pachinko machine 2 of the island facility 50 is arranged. When the player has a problem with the pachinko machine 2, the caller 54 calls the hall member to the pachinko machine 2 where he / she plays. It is turned on when you want. Accordingly, if the call lamp 54 is turned on when the operation of the speaker 21b is abnormal, it is difficult for a hall member to check the pachinko machine 2, so that the hall member can recognize the operation abnormality of the speaker 21b. If the speaker 21b is destroyed as a preparatory action for fraud, the call lamp 54 is turned on so that the hall member is difficult to check the pachinko machine 2, thereby making it difficult for the fraud It can also be prevented. That is, the call lamp 54 functions as a notification unit that notifies the abnormal operation of the speaker 21b.
