Description

  The present invention relates to a gaming machine such as a pachinko machine.

  One type of gaming machine is a ball game machine such as a pachinko machine. Such a ball game machine is provided with a launching device for launching a game ball into the game area. As a launching device, a solenoid type device is known in which a plunger is driven linearly by excitation of a solenoid, and a tip of a rod provided integrally with the plunger is caused to collide with a game ball to strike the game ball.

Generally, a solenoid unit used in a launcher is slidable in a solenoid composed of a cylindrical bobbin and a coil wound around the bobbin, a yoke that supports the solenoid, and an inner hole of the solenoid (bobbin). A number of members such as a plunger to be disposed, a rod provided integrally with the plunger, a bearing member that slidably supports the rod, and a bearing holding member that holds the bearing member are assembled .

Therefore, an assembly error of each member is likely to occur , and the coaxiality of each member such as a solenoid, a yoke, and a plunger (rod) may be reduced.

When the coaxiality is reduced, the dynamic behavior of the solenoid unit becomes unstable, and the force is not transmitted stably to the game ball, and the launch operation becomes unstable, such as variations in the game ball flying. .

  In order to solve such a problem, for example, a conventional technique in which a cylindrical part is projected from both ends of a bobbin along an inner hole and the cylindrical part is engaged with a bearing holding member to increase the coaxiality, A conventional technique is known in which the plunger is accommodated in the pipe and the pipe is inserted into the inner hole of the coil bobbin to improve the coaxiality (see, for example, Patent Document 1).

JP-A-10-97920

  However, in the above prior art, the protruding cylindrical portion of the bobbin and the pipe are inserted into the insertion hole formed in the yoke so as to communicate with the inner hole of the solenoid (bobbin). These pipes are required to have a certain thickness from the viewpoint of securing strength. This inevitably increases the distance between the plunger disposed inside the pipe or the like and the inner peripheral edge of the insertion hole of the yoke that forms the magnetic circuit. Since the dynamic characteristic of the solenoid unit is inversely proportional to the square of the size of the air gap, the dynamic characteristic of the solenoid unit deteriorates when the air gap widens. As a result, there is a possibility that the launching operation of the game ball becomes unstable.

  The present invention has been made to solve the above-described problems and the like, and an object thereof is to provide a gaming machine including a launching device including a solenoid unit having high coaxiality and good dynamic characteristics. is there.

In order to achieve the above object, a gaming machine according to the present invention provides:
The plunger is linearly driven along a predetermined axial direction by excitation of a solenoid, and an output shaft provided along the axial direction integrally with the plunger is caused to collide with the gaming ball, thereby directing the gaming ball to the gaming area. A gaming machine equipped with a launching device for launching,

As described above, there is a ball game machine such as a pachinko machine as a kind of game machine. Such a ball game machine is provided with a launching device for launching a game ball into the game area. As a launching device, a solenoid type device is known in which a plunger is driven linearly by excitation of a solenoid, and a tip of a rod provided integrally with the plunger is caused to collide with a game ball to strike the game ball.

Generally, a solenoid unit used in a launcher is slidable in a solenoid composed of a cylindrical bobbin and a coil wound around the bobbin, a yoke that supports the solenoid, and an inner hole of the solenoid (bobbin). A number of members such as a plunger to be disposed, a rod provided integrally with the plunger, a bearing member that slidably supports the rod, and a bearing holding member that holds the bearing member are assembled.

For example, the yoke comprises a yoke body and a yoke lid, and these are connected and fixed by caulking while sandwiching a solenoid (bobbin), so that the yoke and the solenoid are integrally connected and fixed. It becomes a state. The bearing holding member that holds the rod bearing member is assembled to the outside of the yoke by a fixing means such as a screw.

Therefore, an assembly error of each member is likely to occur, and the coaxiality of each member such as a solenoid, a yoke, and a plunger (rod) may be reduced due to the accumulation of the assembly error.

When the coaxiality is reduced, the dynamic behavior of the solenoid unit becomes unstable, and the force is not transmitted stably to the game ball, and the launch operation becomes unstable, such as variations in the game ball flying. .

For this reason, conventionally, the concentricity of each member has to be maintained with high accuracy, and high assembling accuracy is required, resulting in an increase in manufacturing cost.

In order to solve such a problem, for example, a conventional technique in which a cylindrical part is projected from both ends of a bobbin along an inner hole and the cylindrical part is engaged with a bearing holding member to increase the coaxiality, A conventional technique is known in which the plunger is accommodated in the pipe and the pipe is inserted into the inner hole of the coil bobbin to improve the coaxiality (see, for example, Patent Document 1).

However, in the above prior art, the protruding cylindrical portion of the bobbin and the pipe are inserted into the insertion hole formed in the yoke so as to communicate with the inner hole of the solenoid (bobbin). These pipes are required to have a certain thickness from the viewpoint of securing strength. This inevitably increases the distance between the plunger disposed inside the pipe or the like and the inner peripheral edge of the insertion hole of the yoke that forms the magnetic circuit. Since the dynamic characteristic of the solenoid unit is inversely proportional to the square of the size of the air gap, the dynamic characteristic of the solenoid unit deteriorates when the air gap widens. As a result, there is a possibility that the launching operation of the game ball becomes unstable.

The present invention has been made to solve the above-described problems and the like, and an object thereof is to provide a gaming machine including a launching device including a solenoid unit having high coaxiality and good dynamic characteristics. is there.

A force to fasten the engaging pieces 811d and 812d of the front and rear yokes 811 and 812 in the vertical direction and a force to make a relative displacement in the front and rear direction are applied in contact with the left and right side edge portions.

  More specifically, as the screw 820 is tightened, the position of the screw 820 with respect to the insertion hole 812h is relatively displaced in the rearward direction with a larger left-right width due to contact with the left and right side edges of the insertion hole 812h. . That is, the front yoke 811 having the screw hole 811h into which the screw 820 is screwed is relatively displaced rearward with respect to the rear yoke 812 having the insertion hole 812h. Accordingly, by tightening the screw 820, the front and rear yokes 811 and 812 are connected and fixed, and the intervals between the support wall portions 811a and 812a of the front and rear yokes 811 and 812 are narrowed. Pinch. As a result, the flange portions 813c and 814c of the auxiliary yokes 813 and 814 are sandwiched between the support wall portions 811a and 812a of the yokes 811 and 812 and the flange portions 803c of the bobbin 803.

  When the engagement protrusion 811e of the support wall 811a of the front yoke 811 is pressed against the front end of the upper wall 812b and the lower wall 812c of the rear yoke 812, the front and rear yokes 811 and 812 are connected and fixed. Is completed.

The VDP 526 adjusts the respective timings of the CPU 521, the video RAM 524, etc. to intervene in reading and writing data, and reads the display data stored in the video RAM 524 at a predetermined timing and causes the decorative symbol display device 42 to display it.

  The power supply device 313 includes a power supply unit 541 that supplies power to each unit of the pachinko machine 10, a power failure monitoring circuit 542 that monitors power interruption due to a power failure, and a RAM erase switch circuit 543 connected to the RAM erase switch 323. And. The power supply unit 541 supplies necessary operation power to the main control device 261, the payout control device 311 and the like through a power supply path (not shown). As its outline, the power supply unit 541 takes in AC 24 volt power supplied from the outside, generates + 12V power for driving various switches and motors, + 5V power for logic, backup power for RAM backup, etc. These + 12V power supply, + 5V power supply and backup power supply are supplied to the main control device 261, the payout control device 311 and the like. Note that operation power (+12 V power, +5 V power, etc.) is supplied to the launch control device 312 via the payout control device 311.

  The power failure monitoring circuit 542 is a circuit that outputs a power failure signal SK1 to each NMI terminal of the CPU 501 of the main control device 261 and the CPU 511 of the payout control device 311 when the power is cut off due to the occurrence of a power failure or the like. The power failure monitoring circuit 542 monitors the DC stable voltage of 24 volts, which is the maximum voltage output from the power supply unit 541, and determines that a power failure (power failure) has occurred when this voltage is less than 22 volts. The power failure signal SK1 is output to the main controller 261 and the payout controller 311. Based on the output of the power failure signal SK1, the main control device 261 and the payout control device 311 recognize the occurrence of a power failure and execute a power failure process (NMI interrupt processing).

  The power supply unit 541 normally outputs an output of 5 volts, which is a drive voltage of the control system, for a time sufficient to execute the process at the time of a power failure even after the DC stable voltage of 24 volts becomes less than 22 volts. Configured to maintain the value. Therefore, the main control device 261 and the payout control device 311 can normally execute and complete the power failure process.

  The RAM erase switch circuit 543 is a circuit that takes in the switch signal of the RAM erase switch 323 and clears backup data in the RAM 503 of the main controller 261 and the RAM 513 of the payout controller 311 in accordance with the state of the switch 323. When the RAM erase switch 323 is pressed, the RAM erase switch circuit 543 outputs a RAM erase signal SK2 to the main controller 261 and the payout controller 311. When the power of the pachinko machine 10 is turned on with the RAM erase switch 323 pressed (including power-on due to power failure cancellation), the data in the respective RAMs 503 and 513 are cleared in the main controller 261 and the payout controller 311. The

  As described above in detail, in this embodiment, the member that holds the bearing member 815 of the rod 808 is constituted by the auxiliary yokes 813 and 814 that are members constituting the yoke 806, and the auxiliary yokes 813 and 814. Are assembled in a state of being positioned with respect to the yoke main bodies 811 and 812 and the bobbin 803, respectively. As a result, the accumulation of assembly errors of each member such as the solenoid 805, the yoke 806, the plunger 807 (output shaft 808) can be reduced, and the decrease in the coaxiality of each member can be suppressed. As a result, the assembling work for increasing the coaxiality can be simplified, and an increase in manufacturing cost can be suppressed.

  Further, in the present embodiment, in order to increase the coaxiality, the member inserted into the yoke main bodies 811 and 812 is not a pipe made of a non-magnetic material as in the prior art, but a magnetic part constituting a part of the yoke 806. These are the body auxiliary yokes 813 and 814. For this reason, since a nonmagnetic material is not interposed between the plunger 807 and the inner peripheral edge portions of the mounting holes 811g and 812g of the yoke bodies 811 and 812 that together form a magnetic circuit, the air gap X (see FIG. 18) is provided. It can be made relatively small, and deterioration of the dynamic characteristics of the solenoid unit 800 can be suppressed.

  As a result, the dynamic characteristics of the solenoid unit 800 can be stabilized, and the game ball launching operation can be stabilized. Furthermore, the solenoid unit 800 having high coaxiality and good dynamic characteristics can be manufactured at low cost.

  In this embodiment, the engagement pieces 811d and 812d of the front and rear yokes 811 and 812 are overlapped with each other along the vertical direction perpendicular to the axis C1 direction (drive direction of the plunger 807). The front and rear yokes 811 and 812 are connected and fixed by inserting a screw 820 through the insertion hole 812h and screwing the screw 820 into the screw hole 811h of the front yoke 811. Thereby, the screw 820 is relatively difficult to loosen.

  Further, the insertion hole 811h has a long hole shape that is long in the front-rear direction, and the width of the insertion hole becomes narrower toward the front. On the other hand, the screw 820 has a head portion 820b having a tapered diameter. As a result, by tightening the screw 820, the front and rear yokes 811 and 812 are connected and fixed, and the support wall portions 811a and 812a of the front and rear yokes 811 and 812 are narrowed. 803 can be held. As a result, the flange portions 813c and 814c of the auxiliary yokes 813 and 814 can be held by the support wall portions 811a and 812a of the yokes 811 and 812 and the flange portions 803c of the bobbin 803.

  With such a configuration, a special device such as a caulking press device is not required for connecting the components of the yoke 806, and the operation can be simplified, so that an increase in manufacturing cost can be suppressed. In addition, even when a defective product is generated, the connection of the constituent members of the yoke 806 can be released and the constituent members of the yoke 806 can be reused.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) The shape, material, size, and the like of each component of the solenoid unit 800 are not limited to the above embodiment. For example, in the above-described embodiment, the inner diameters of the inner holes 813f and 814f of the main body portions 813a and 814a of the auxiliary yokes 813 and 814 are formed substantially the same as the inner diameter of the inner hole 803b of the bobbin 803. For example, the inner diameters of the inner holes 813f and 814f of the auxiliary yokes 813 and 814 may be smaller than the inner diameter of the inner hole 803b of the bobbin 803, and the interval of the air gap X may be made smaller.

  (B) In the above embodiment, the front and rear yokes 811 and 812 are connected and fixed by the screw 820 by making the shape of the insertion hole 811h uneven, and the support wall portions 811a and 812a of the front and rear yokes 811 and 812 are connected. It is the structure which narrows the space | interval. However, the configuration for connecting and fixing the front and rear yokes 811 and 812 is not limited to this. For example, even if the insertion hole 812h of the rear yoke 812 is a perfect circle and the insertion direction of the screw 820 is simply the vertical direction perpendicular to the direction of the axis C1, the screw 820 is less likely to loosen. .

  (C) You may implement as a type of pachinko machine different from the said embodiment. In addition to pachinko machines, various game machines such as an arrangement ball machine and a sparrow ball similar thereto may be used.

  According to the means 1, the member that holds the bearing member of the output shaft is constituted by the auxiliary yoke that is one member constituting the yoke, and the auxiliary yoke is positioned with respect to the yoke body and the bobbin. It is assembled. As a result, the accumulation of assembly errors of each member such as a solenoid, a yoke, and a plunger (output shaft) can be reduced, and a decrease in the coaxiality of each member can be suppressed. As a result, the assembling work for increasing the coaxiality can be simplified, and an increase in manufacturing cost can be suppressed.

  Further, in this means 1, in order to increase the coaxiality, the member inserted into the yoke body is not a pipe made of a non-magnetic material as in the prior art, but a magnetic auxiliary yoke constituting a part of the yoke. It is. For this reason, since a non-magnetic material is not interposed between the plunger and the inner peripheral edge of the mounting hole of the yoke body that together forms a magnetic circuit, the air gap can be made relatively small and the dynamic characteristics of the solenoid unit are deteriorated. Can be suppressed.

  As a result, the dynamic characteristics of the solenoid unit can be stabilized, and the launching action of the game ball can be stabilized. Furthermore, a solenoid unit having high coaxiality and good dynamic characteristics can be manufactured at low cost.

  A conventional yoke is generally composed of two yoke components, and these yokes and a solenoid are integrally connected and fixed by caulking or the like while sandwiching a solenoid (bobbin). It becomes. The bearing holding member that holds the output shaft bearing member is then assembled to the outside of the yoke by a fixing means such as a screw.

  However, in the caulking process, a press device is required, and if a defective product is found after the process, the product cannot be recycled. On the other hand, according to this means, a special device is not required to perform the connecting operation of the yoke constituent members, and the operation can be simplified, so that an increase in manufacturing cost can be suppressed. Further, even when a defective product is generated, the yoke constituent member can be disconnected and the yoke constituent member can be reused, so that the recyclability is excellent.

  In addition, since vibration is constantly applied in the plunger drive direction (axial direction) during operation, if the insertion direction of the screw means is parallel to the plunger drive direction, the screw means is likely to loosen. Is concerned. On the other hand, in this means, since the insertion direction of the screwing means is in a direction perpendicular to the driving direction of the plunger, the screwing means is relatively difficult to loosen.

Means 3. The first yoke body located on the inward side is tapered at a location where the first yoke body and the second yoke body are arranged so as to overlap with the direction orthogonal to the axial direction.
