Description

  The present invention relates to a catcher of a game machine, and in particular, it is possible to accurately control the get rate of prizes of a two-arm game machine and to set the two game machines with simple settings so as to ensure fairness. The present invention relates to a catcher for a game machine capable of changing the holding force of the catcher and a game machine equipped with the catcher.

  A game machine having a three-arm type catcher is known as a catcher of a conventional game machine (see, for example, Patent Document 1). As shown in FIG. 7, a “single catcher catcher game machine” shown in this patent document 1 and the Republic of China public notice No. M407094 describes a three-arm catcher structure 9. This game machine has three catchers 91, 92, 93, and each base end side is pivotally connected to one pivot seat 951 by a first pivot portion 94. The pivot seat 951 is fixed to a shaft rod 952 of one electromagnetic valve 95. Further, the base end side portions of the intermediate portions of the three catchers 91, 92, 93 are pivoted to one end of the connecting arm 97 by the second pivotal portion 96. The ends of the connecting arms 97 are fixed to the base of the catcher structure 9 respectively. When the player gives a command to hold the prize, the shaft 952 is expanded and contracted by the electromagnetic valve 95, and the lower ends of the three catchers 91, 92, and 93 are opened and closed. By such control, prizes such as stuffed animals displayed in the game machine can be held together.

  A two-arm game machine is also known as a catcher of a conventional game machine (see, for example, Patent Document 2). As shown in FIG. 8, the “game apparatus for acquiring prizes” shown in Patent Document 2 and the Republic of China No. 200914102 describes a two-arm type catcher structure 8. The catcher structure 8 has two catchers 81, and the base ends of the catchers are pivoted to the base of the catcher structure by the first pivotal portions 82, respectively, and the middle portion of the two catchers 81 is the second catcher 81. Each of the pivot plates 83 is pivotally connected to the operation plate 84. The two actuating plates 84 are interlocked so as to move relative to each other by the power member 85, and when moved away from each other, the lower ends of the two catchers 81 are opened away from each other. When the player gives a command to hold the prize, the two operation plates 84 move in a relatively approaching direction, and the catcher connecting the free end 861 of the helical expansion spring 86 is pulled by this expansion spring. The two catchers 81 are formed so that the lower ends thereof are close to each other so that prizes in the game machine can be held.

Republic of China Notice No. M407094 Republic of China No. 200914102

  In the three-arm type catcher structure 9 described in Patent Document 1 and the Republic of China Notification No. M407094 described above, the shaft catch 952 is controlled by the electromagnetic valve 95 to synchronize the three catchers 91, 92, 93. The three-arm game machine lacks technicality and realism because it can be extended and contracted or released. In addition, since the player already clearly understands that the prize get rate of the above-mentioned game machine can control the get rate of the prize by an artificial control method, the game machine of the three-arm type is for the player. There was a problem that the customer suction power was lost.

  Further, in the two-arm type catcher structure 8 described in the above-mentioned Patent Document 2 and the Republic of China No. 200914102, the contractor of the game machine replaces the expansion spring 86 so that the elastic coefficient of the expansion spring 86 is changed. Or the extension amount of the extension spring 86 can be changed by adjusting the position of the fixed end 862 opposite to the free end 861. Thereby, by changing the elastic coefficient of the expansion spring 86 or the extension amount thereof, the tensile force that the expansion spring 86 gives to the catcher 81 can be set appropriately, and the force that the two catchers 81 hold the prizes can be set. Can be controlled.

  However, the operation of changing the elastic coefficient or the extension amount of the expansion spring 86 has to open the inside of the game machine, and the operation is relatively troublesome. In addition, since the state of the expansion spring is easy to be detected by the player, the range of selection varies depending on the person in the above game machine, and the prize get rate is low depending on the player, which is relatively unfair to such a player. Result. On the other hand, an experienced player can select and play only game machines whose elasticity coefficient of the expansion spring 86 is advantageous to get a prize, which is unfavorable for game machine vendors. It was.

  Based on the above-described causes, the above-described game machine should be further improved.

  The present invention was invented in view of such problems, and the first problem to be solved is a catcher for a game machine capable of accurately controlling the get rate of prizes and a game machine using the same Is to try to provide.

  A second problem to be solved by the present invention is to provide a game machine catcher capable of easily changing a prize get rate and a game machine using the same.

  A third problem to be solved by the present invention is to provide a game machine catcher capable of ensuring that all players play the game machine on the principle of fairness, and a game machine using the same.

  In order to achieve the above object, a catcher of a game machine according to the present invention includes a main body and two catchers. The main body has one control module, and the control module controls the rotation of the two power members. Further, the main body is provided with two detection members and two micro switches. The base end side of the catcher is separately fitted to the rotation shaft of the power member so as to be rotatable, and the lower end sides of the two catchers can be opened and closed. Each of the two catchers is provided with a stop portion. When the stop portion rotates to a position where it comes into contact with the microswitch, the power member stops. A power board and a torsion spring are coaxially provided on the side face of the base end side of the two catchers, and the power board is directly connected to the rotating shaft so as to rotate in the forward and reverse directions by the power member. Has been. The power board is provided with a tooth part, and the tooth part corresponds to a detection member of the main body, the number of rotations of the power panel is calculated, and the start and stop of the power member are controlled according to the number of rotations. . One end of the torsion spring is fixed to the catcher and the other end is fixed to the power panel, and a restoring force is accumulated in the catcher by the torsional force of the torsion spring.

  In addition, the catcher of the game machine according to the present invention is provided with two guide bars in the main body, one guide groove is provided in each of the two catchers, and each of the two guide bars is separately provided in the above two guide bars. It can also be inserted into the individual guiding grooves. Further, a casing can be provided for each of the two catchers, a hook can be provided for each of the power panels, and the free ends of the torsion springs can be fixed to the casing and the hook, respectively.

It is explanatory drawing which shows an example of the catcher structure of the other conventional game machine.

  An embodiment of the present invention will be described below with reference to the drawings.

  FIG. 1 is a perspective view showing an embodiment of the present invention with a cover removed, and FIG. 2 is an exploded perspective view showing details of the embodiment of the present invention. 1 and 2, the catcher of the game machine according to the present invention includes a main body 1 and two catchers 2. The two catchers 2 are separately pivoted to the main body 1 as will be described later, and each catcher 2 is provided so as to be indirectly linked to each other by a power member 11 such as a motor. Then, when the lower ends of the two catchers 2 are moved in the closing direction, the two catchers 2 are operated to jointly hold the prize in the game machine.

  Referring to FIGS. 1 and 2 again, a housing space is formed in the main body 1, and two power members 11 such as motors are provided in the housing space. The two power members 11 are controlled by one control module 12 to start, stop, and rotate in the rotation direction. As is well known, the control module 12 includes an integrated circuit (IC) chip, a passive circuit element, and the like. The main body is provided with two detection members 13 for detecting the number of rotations of the two power members 11, and as will be described later, the number of rotations is calculated by sensing of the detection members, and the operation member Can be controlled. As the detection member 13, a known Hall sensor or encoder can be used. The main body 1 is provided with a micro switch 14, and when the catcher rotates to a position where the micro switch operates, the operation of the two power members 11 is controlled to stop. A detachable cover 15 is provided on the front surface of the main body 1, and the aesthetic appearance of the main body 1 is maintained by this cover.

  Each of the two catchers 2 has a mounting hole provided on each base end side thereof fitted to a rotation shaft 16 of one power member 11 so as to be rotatable, preferably via a bearing. When 11 rotates, it interlock | cooperates so that it may rotate indirectly with this rotation. The two catchers 2 are formed in a symmetrical shape, and perform a continuous operation so that the lower end opens when moving in a far direction, and the lower catcher can be clamped at the lower end when moving in the approaching direction. Each of the two catchers 2 is provided with one stop portion 21, and when the stop portion 21 comes into contact with the microswitch 14 and generates a signal, the power member 11 is operated so that the catcher 2 continuously rotates. In this state, the two catchers 2 are formed to open to the maximum amount.

  A power shaft 22 and a torsion spring 23 are provided coaxially with the catcher on the rotating shaft 16 that rotatably supports the two catchers 2 along the side surfaces of the respective catchers. The power board 22 is directly connected to the rotating shaft in a non-rotating state so as to rotate in the forward and reverse directions by the rotating shaft 16. This power board has a power board attached to the rotating shaft and a disk-like rotating plate fixed to the power board with screws, and a slit extending in the radial direction is formed on the peripheral edge of the rotating board of the power board 22. The tooth part 221 is provided. The tooth member 221 corresponds to the detection member 13 provided on the main body 1. Therefore, the number of rotations of the power board 22 can be accurately calculated by measuring the number of passages of the tooth portion by the detection member 13, and the operation of the power member can be controlled based on this calculation. The free end of the torsion spring 23 has one end fixed to the catcher 2 and the other end fixed to the power panel 22. In the present embodiment shown in the figure, one end of the torsion spring 23 is fixed to a housing 24 protruding from the catcher 2, and the other end of the torsion spring 23 is fixed to a flange 222 protruding from the power board of the power panel 22. ing. When the power board rotates, the torsion spring 23 is twisted, and the restoring force is accumulated in the catcher 2 by the torsional force. The casing 24 and the casing 222 are provided at positions where they can contact when the catcher rotates in the direction in which the lower end of the catcher opens.

  The catcher 2 preferably secures a rotation range so as to rotate within a predetermined angle range with respect to the main body 1. In the embodiment, an arcuate guiding groove 25 is installed on the base end side of the catcher 2, and a guiding rod 17 is installed on the main body 1 so as to protrude into the guiding groove. Since the guide rod 17 is inserted into the guide groove 25, the catcher 2 rotates within a predetermined angle range relative to the main body 1 until the guide rod hits the edge of the guide groove. To be secured.

  FIG. 3 is a front view of the assembled state. Referring to FIG. 3, when the two catchers 2 are not operating, the two catchers 2 are further fitted into the guide groove 25 by the torsional force of the torsion spring 23. By being inserted, it is held within a predetermined angle.

  FIG. 4 is an explanatory view showing a state in which the two catchers shown in FIG. 3 are opened. Referring to FIG. 4, the two catchers 2 are opened to the maximum angle by the opening operation. The two catchers 2 are rotated in conjunction with the power board 22 when the power board 22 is rotated by the rotation shaft 16 of the power member 11. That is, when the power board 22 rotates, the hook 222 comes into contact with the casing 24 of the catcher 2, and the rotation of the power board is transmitted to the catcher, and the catcher 2 is interlocked and indirectly by the power member 11. Rotate. This rotation continues until the stop portions 21 of the two catchers 2 come into contact with the microswitch 14, and the guide rod 17 comes into contact with one end of the guide groove 25 when it comes into contact with the microswitch. It is formed as follows. Further, as shown in FIG. 4, in the process in which the catcher 2 is rotated by the power board 22, the torsion spring 23 only rotates within a minute range until both ends approach.

  FIG. 5 is a front view showing a state where two catchers catch a prize from the state shown in FIG. Referring to FIG. 5, the two catchers 2 are in a state where the lower ends approach each other to catch a prize. Explaining this state, the two power members 11 provided in the main body 1 rotate in the direction opposite to that in FIG. With this rotation, the two catchers 2 rotate in conjunction with the respective power members 11 via torsion springs, and the lower ends approach. At this time, the power boards 22 of the two catchers 2 are in a state of being wound in conjunction with the torsion springs 23 provided on each of them. Further, since the two catchers 2 are rotated in the direction in which the two catchers 2 approach each other indirectly by the torsional force of the two torsion springs 23, the prize is strongly held between the lower ends of the two catchers 2. Can do.

  FIG. 6 is an explanatory view showing a state where one of the two two catchers shown in FIG. 5 is loosened. Referring to FIG. 6, one of them, the left catcher 2 in FIG. 6 is loosened and a state in which the prize cannot be strongly clamped is shown. Such a state can be obtained by controlling the control module 12 so that the two power members 11 are separately operated in advance by a game machine supplier controlling the control module 12 to drive the two power members 11. . That is, when the power boards 22 of the two power members 11 are rotated and the torsion springs 23 are rotated in conjunction with each other, if the number of rotations of the two power boards is changed, the two torsion springs 23 have different windings. It becomes a state of entrainment of numbers.

  That is, one torsion spring 23 has a relatively large torsional force, and the other torsion spring 23 has a relatively small torsional force. If it does in this way, the clamping force with respect to the prize by the two catchers 2 will become uneven. Then, the catcher 2 having a relatively large torsional force of the torsion spring 23 generates a force for pushing the catcher 2 having a relatively small torsional force to be thrust toward the torsion spring 23, so that the prize cannot be reliably caught. It can be formed so as to be easily dropped.

  On the other hand, when the torsional forces of the two torsion springs are different, the game machine vendor uses the control program provided in advance in the control module 12 to operate the two power members 11 separately. When the torsion springs 23 are rotated in conjunction with the power panels 22 of the two power members 11, the two torsion springs 23 can be formed in the same winding number. The two torsion springs 23 can be configured to have the same torsional force.

  If it does as mentioned above, since the clamping force of the two catchers 2 can be formed equally with respect to the prize, it becomes easy to catch the prize and it is difficult to fall in the process of movement. As described above, the control program stored in the control module 12 can control whether or not the average catching force is applied to the two catchers 2 with a predetermined probability, and the player holds the prize. The success rate can be precisely controlled.

  Further, since the number of rotations of the two power members 11 can be sensed and calculated by the two detection members 13, the power panels of the two power members 11 are controlled by a control program provided in advance in the control module 12. The amount of rotation of the torsion spring 23 can be controlled by accurately controlling the number of rotations 22, thereby effectively controlling the force with which the two catchers 2 hold the prize. In other words, the force with which the two catchers 2 hold the prize can be accurately set by the control program stored in the control module 12, and adjustment and maintenance can be easily performed.

  According to the catcher of the game machine of the present invention, the two power members 11 are controlled and driven by the control program provided in advance so that the two power members 11 are operated separately by the control program provided in advance. The clamping force of the individual catchers 2 can be formed unevenly. Such two catchers 2 have a relatively realistic feeling in operation, and can accurately control the success rate of the prize get. Furthermore, since the success points are distributed, it is possible to deal fairly with all players, and to prevent unfair circumstances. When trying to change the winning rate of prizes, it is only necessary to change the control program, so that it can be easily adjusted.

  The present invention may be implemented in other ways without departing from the spirit and essential characteristics thereof. Accordingly, the preferred embodiments described herein are exemplary and are not intended as limitations on the scope of the invention.
