Description

  The present invention relates to a solenoid electromagnet, a solenoid, and a gaming machine such as a pachinko machine or a slot machine using the solenoid.

  Conventionally, for example, there is a pachinko machine as a representative example of the gaming machine. As this pachinko machine, for example, a receiving part that receives rented game balls and game balls that have been paid out, a ball feeding device that sends out the game balls one by one in the receiving part, and a ball feeding device Game ball launching device that launches the game ball with the strength according to the player's operation, and the area where the game ball launched from this game ball launching device is driven, and various game parts such as winning holes Some have a game board or the like having a game area in which is arranged.

  In addition, the ball feeding device includes a container body having an inlet portion to which a game ball from the tray portion is input and an outlet portion for outputting the game ball, and a ball feeding solenoid provided inside the container body. I have. This ball feed solenoid is roughly divided into an electromagnet made of a U-shaped fixed core around which a coil is wound, and an iron plate disposed so as to be substantially opposed to each other in the vicinity of both ends of the fixed core. And a movable piece. The movable piece is pivotally supported at a predetermined location (a location near one distal end of the U-shaped fixed core) of the container body, and the distal end of the movable piece is separated from the fixed core and approaches the fixed core. It is supported so that it can be displaced in the state where

  The movable piece is displaced as follows. That is, by energizing the coil, an annular magnetic circuit is formed so as to pass through the U-shaped fixed iron core, and the tip of the movable piece is sucked to the other tip of the U-shaped fixed iron core. A force is generated, and the movable piece of the ball feed solenoid enters a suction state. Further, when the energization to the coil is stopped, the magnetic circuit is not formed, the attraction force is attenuated, and the leading end side of the movable piece is in a non-attracting state away from the other leading end side of the U-shaped fixed core. .

Below, operation | movement of a movable piece is demonstrated from a viewpoint of sending out of a game ball. That is, the leading game ball that has reached the entrance and is stopped by the non-suction movable piece is taken into the movable piece when the movable piece is in the suction state. When the movable piece returns to the non-suction state, the taken game ball is released to the outlet portion, and the next game ball is stopped at the inlet portion by the movable piece as described above. As described above, the movable piece of the ball feed solenoid is driven to be displaced between the suction state and the non-suction state, so that the game balls input to the inlet portion are discharged one by one from the outlet portion and sent to the game ball launching device. (For example, refer to Patent Document 1).
Japanese Patent Laid-Open No. 11-124552 (page 4-5, FIG. 7-8)

However, the conventional example having such a configuration has the following problems.
That is, in the conventional pachinko machine, for example, if the ball feed solenoid of the ball feeder is energized to the coil and the movable piece is in contact with the fixed iron core, Since the attraction force remains due to residual magnetism that circulates between the fixed iron core and the iron plate of the movable piece and the movable piece does not leave, there is a predetermined gap between the fixed iron core and the iron plate of the movable piece in the attracted state. A positioning member for positioning with a slight gap is provided in the container body separately from the ball feed solenoid, but this gap changes depending on the relative mounting position relationship between the electromagnet, the movable piece, and the positioning member. Therefore, this gap adjustment work is not only complicated as described below, but also has a problem that the mounting accuracy varies.

  In other words, if the movable piece is too close to the fixed iron core as a gap by the positioning member, the attracting force due to residual magnetism is large, and the movable piece may be difficult to leave, and if it does not leave, the captured game ball can not be output. Become. On the other hand, if the movable piece is too far away from the fixed iron core as a gap due to the positioning member, sufficient suction force cannot be secured, so the suction state may not be maintained well and may be incomplete. If it is insufficient, the next game ball cannot be taken in.

  In addition, for example, the movable plate may be attracted to the container body by dust etc. due to aging, etc. and may not move with normal suction force, so it is conceivable to use a solenoid with increased suction force. If the number of turns of the coil is increased, the solenoid becomes larger, and the ball feeder becomes larger in order to accommodate the enlarged solenoid. Further, as described above, since the movable piece needs to be separated from the fixed iron core in the non-attraction state, the attraction force due to the residual magnetism is increased in the solenoid with an increased attraction force, and this increased residual magnetic attraction force. A return spring (for example, a spring) that returns the movable piece to forcefully separate it with a stronger force must be provided on the base end side of the movable piece, and the biasing force of the return spring increases as the residual adsorption force increases There is also a problem in that it is not possible to increase only the suction force after all, and the suction force cannot be increased efficiently.

  The present invention has been made in view of such circumstances, and can eliminate the complexity of adjusting the gap between the movable piece and the electromagnet, and can effectively increase the attractive force, and the solenoid electromagnet and the solenoid. An object is to provide a gaming machine using a solenoid.

In order to achieve such an object, the present invention has the following configuration.
That is, the invention described in claim 1
A fixed iron core,
A non-magnetic hollow member having a hollow portion into which the fixed iron core is inserted;
A coil wound around the axis of the fixed iron core on the outer periphery of the hollow member;
In a solenoid electromagnet comprising a magnet-permeable yoke to which a base end side of the fixed iron core in a state of being fitted in the hollow portion of the hollow member around which the coil is wound is fixed,
Before Symbol yoke,
A fixed surface portion through which magnetism is passed , having a fixed support for fixing the base end side of the fixed iron core;
In a state in which the fixed surface portion is viewed from the side, both end sides sandwiching the fixed receiver at the fixed surface portion are respectively provided so as to stand on the side where the fixed core exists, and the fixed core is located between them. With both standing plates that pass through ,
The solenoid electromagnet is displaceable between a state where it is attracted to the tip end side of the fixed iron core by energizing the coil and a state separated from that state, and a movable piece that allows magnetism abuts in a attracted state. A contacted portion located at a location that is a part of the outer peripheral region of the fixed iron core and protrudes from the front end surface of the fixed core;
When the movable piece is brought into a suction state by energizing the coil, the movable piece comes into contact with the contacted portion, and the both standing plate portions are not in contact with each other in the suction direction of the movable piece. It is characterized by.

According to the solenoid electromagnet according to the present invention, to provide a variable Dohen and can eliminate the complexity of clearance adjustment of the electromagnet, the electromagnet solenoid can suction efficiency is increased and the solenoid and the game machine it can.

The present specification also discloses an invention relating to the following gaming machines.
(A0) a fixed iron core;
A non-magnetic hollow member having a hollow portion into which the fixed iron core is inserted;
A coil wound around the axis of the fixed iron core on the outer periphery of the hollow member;
A magnetically permeable yoke to which a proximal end side of the fixed iron core is fitted in the hollow portion of the hollow member around which the coil is wound;
In the electromagnet for solenoid with
A member to which a movable piece of a solenoid in a suction state is abutted, and is located in a peripheral area from a peripheral portion on the front end side of the fixed iron core and at a position protruding from a front end side surface of the fixed iron core With contact
The yoke is
A fixed surface portion having a fixed support for fixing the base end side of the fixed iron core;
A compatible installation plate portion in which both end sides of the fixed surface portion are erected on the side where the fixed iron core exists in a state in which the fixed surface portion is viewed from the side.
And the height of the front end side of both the standing plate portions is lower than the height of the contacted portion.
An electromagnet for a solenoid characterized by that.
According to the invention described in (A0), the solenoid electromagnet includes a stationary iron core, a nonmagnetic hollow member having a hollow portion into which the stationary iron core is inserted, and an outer periphery of the hollow member. A coil wound around an axis, and a magnetically permeable yoke to which a proximal end side of a fixed iron core fitted in a hollow portion of a hollow member wound around the coil is fixed Yes. The abutted part is a member to which the movable piece of the attracted solenoid is abutted, and is a part protruding from the front end side surface of the fixed core in the outer peripheral region than the peripheral end part of the fixed core Located in. The yoke has a fixed surface portion having a fixed support for fixing the base end side of the fixed iron core, and a compatible installation plate in which both end sides of the fixed surface portion are erected on the side where the fixed iron core exists in a state where the fixed surface portion is viewed from the side. And the height of the tip side of both the standing plate parts is lower than the height of the abutted part.
Therefore, when such a solenoid electromagnet is employed in the solenoid, by energizing the coil, the movable piece of the solenoid is attracted to the fixed iron core, and the movable piece comes into contact with the contacted portion. However, the movable piece does not directly contact the fixed iron core and both standing plate parts, but the movable piece is in a state where a predetermined gap is left between the fixed iron core and both standing plate parts. Because it is sucked, the gap can be realized with the manufacturing accuracy of the yoke plate, and the gap adjustment work of adjusting the gap with a positioning member separate from the solenoid as in the conventional example can be made unnecessary. The problem that the mounting accuracy varies can be solved.

  Further, since the yoke is provided with the compatible installation plate portion, when the coil is energized, the first magnetic circuit through which the magnetism passes through the fixed iron core, one upright plate portion and the movable piece, and the fixed iron core and the other upright plate A second magnetic circuit through which magnetism passes through the part and the movable piece can be formed, that is, two annular magnetic circuits can be formed, and the attractive force can be increased. That is, another magnetic circuit can be formed as compared with the conventional one-shaped magnetic circuit, and the attractive force can be increased by the newly formed magnetic circuit. Further, since the movable piece is attracted with a predetermined gap between each of the fixed iron core and both standing plate parts, when the coil is not energized, the magnetic circuit is cut off by the gap and the residual Magnetic attraction force can be extremely reduced, only the attraction force can be increased, and the attraction force can be increased efficiently, with a force stronger than the increased residual magnetic attraction force as in the conventional example. A return spring for returning the movable piece to forcibly separate it can be made unnecessary.

  As a result, it is possible to provide a solenoid electromagnet that can eliminate the complexity of adjusting the gap between the movable piece and the electromagnet, and can efficiently increase the attractive force.

  In addition, when the coil is energized, the movable piece of the solenoid is attracted to the fixed iron core, and this movable piece comes into contact with the contacted portion, but the movable piece is directly attached to the fixed iron core and both standing plate parts. Since the gap is formed between each of the fixed iron core and both the standing plate portions, the permanent movement of the movable piece can be reduced.

  As described above, the contacted portion is located at a position protruding from the surface on the front end side of the fixed iron core, but the protruding amount is small, that is, a minute protrusion. That is, the protrusion amount is preferably a distance that can reduce the permanent magnetization of the movable piece.

(B0) The solenoid electromagnet according to (A0) is provided,
A solenoid including a movable piece that is displaceable between a state of being attracted to a front end side of the fixed iron core and a state of being separated from the state .

According to the invention described in (B0) , the solenoid includes the solenoid electromagnet and the movable piece. An electromagnet for solenoid includes a fixed iron core, a nonmagnetic hollow member having a hollow portion into which the fixed iron core is inserted, and a coil wound around the axis of the fixed iron core around the hollow member And a magnetically permeable yoke to which the base end side of the fixed iron core fitted in the hollow portion of the hollow member around which the coil is wound is fixed. The abutted part is a member to which the movable piece of the attracted solenoid is abutted, and is a part protruding from the front end side surface of the fixed core in the outer peripheral region than the peripheral end part of the fixed core Located in. The yoke has a fixed surface portion having a fixed support for fixing the base end side of the fixed iron core, and a compatible installation plate in which both end sides of the fixed surface portion are erected on the side where the fixed iron core exists in a state of viewing the fixed surface portion. And the height of the tip side of both the standing plate parts is lower than the height of the abutted part. The movable piece is displaceable between a state where the movable piece is attracted to the front end side of the fixed iron core and a state where the movable piece is separated from the state.

  Therefore, in the case of a solenoid having such a solenoid electromagnet, when the coil is energized, the movable piece of the solenoid is attracted to the fixed iron core, and the movable piece comes into contact with the contacted portion. The movable piece is not in direct contact with the fixed iron core and both standing plate parts, but the movable piece is sucked with a predetermined gap between each of the fixed iron core and both standing plate parts. Therefore, the gap can be realized with the manufacturing accuracy of the yoke compatible plate part, and the gap adjustment work of adjusting the gap with a positioning member separate from the solenoid as in the conventional example can be made unnecessary. The problem that the mounting accuracy varies can be solved.

  Further, since the yoke is provided with the compatible installation plate portion, when the coil is energized, the first magnetic circuit through which the magnetism passes through the fixed iron core, one upright plate portion and the movable piece, and the fixed iron core and the other upright plate A second magnetic circuit through which magnetism passes through the part and the movable piece can be formed, that is, two annular magnetic circuits can be formed, and the attractive force can be increased. That is, another magnetic circuit can be formed as compared with the conventional one-shaped magnetic circuit, and the attractive force can be increased by the newly formed magnetic circuit. Further, since the movable piece is attracted with a predetermined gap between each of the fixed iron core and both standing plate parts, when the coil is not energized, the magnetic circuit is cut off by the gap and the residual Magnetic attraction force can be extremely reduced, only the attraction force can be increased, and the attraction force can be increased efficiently, with a force stronger than the increased residual magnetic attraction force as in the conventional example. A return spring for returning the movable piece to forcibly separate it can be made unnecessary.

  As a result, it is possible to provide a solenoid capable of eliminating the complexity of adjusting the gap between the movable piece and the electromagnet and efficiently increasing the attractive force.

  In addition, when the coil is energized, the movable piece of the solenoid is attracted to the fixed iron core, and this movable piece comes into contact with the contacted portion, but the movable piece is directly attached to the fixed iron core and both standing plate parts. Since the gap is formed between each of the fixed iron core and both the standing plate portions, the permanent movement of the movable piece can be reduced.

  According to the invention described in (1), the abutted portion is a peripheral protruding portion that protrudes at least at the peripheral portion on the distal end side of the hollow member from the surface on the distal end side of the fixed core. The height of the tip side of both the standing plate portions of the yoke is set lower than the height of the peripheral protrusion on the tip side of the hollow member.

  Therefore, when such a solenoid electromagnet is used for the solenoid, by energizing the coil, the movable piece of the solenoid is attracted to the fixed iron core, and this movable piece contacts the peripheral protrusion on the distal end side of the hollow member. The movable piece is not in direct contact with the fixed iron core and both standing plates, but the movable piece has a predetermined gap with respect to each of the stationary core and both standing plates. The gap is adjusted with a positioning member that is separate from the solenoid as in the conventional example. Can be eliminated, and the problem that the mounting accuracy varies can be solved.

  Further, since the yoke is provided with the compatible installation plate portion, when the coil is energized, the first magnetic circuit through which the magnetism passes through the fixed iron core, one upright plate portion and the movable piece, and the fixed iron core and the other upright plate A second magnetic circuit through which magnetism passes through the part and the movable piece can be formed, that is, two annular magnetic circuits can be formed, and the attractive force can be increased. That is, another magnetic circuit can be formed as compared with the conventional one-shaped magnetic circuit, and the attractive force can be increased by the newly formed magnetic circuit. Further, since the movable piece is attracted with a predetermined gap between each of the fixed iron core and both standing plate parts, when the coil is not energized, the magnetic circuit is cut off by the gap and the residual Magnetic attraction force can be extremely reduced, only the attraction force can be increased, and the attraction force can be increased efficiently, with a force stronger than the increased residual magnetic attraction force as in the conventional example. A return spring for returning the movable piece to forcibly separate it can be made unnecessary.

  As a result, it is possible to provide a solenoid electromagnet that can eliminate the complexity of adjusting the gap between the movable piece and the electromagnet, and can efficiently increase the attractive force.

  In addition, when the coil is energized, the movable piece of the solenoid is attracted to the fixed iron core, and this movable piece comes into contact with the peripheral protrusion on the distal end side of the hollow member. Instead of directly contacting the plate portion, the gap between the fixed iron core and the both standing plate portions is provided, so that it is possible to reduce the permanent magnetization of the movable piece.

  Furthermore, since the abutted portion is a peripheral protrusion that protrudes from the front end surface of the fixed iron core at least at the peripheral portion on the front end side of the hollow member, the outer peripheral side of the hollow member is separate from the hollow member. Since there is no need to provide a dedicated contact portion, the space merit is high and the heat dissipation is not deteriorated.

(2) In the electromagnet for solenoid according to (1),
The metal of the movable piece of the solenoid is disposed on the distal end side of the first standing plate portion, which is the upright plate portion closer to the base end side of the movable piece of the solenoid, of the both standing plate portions. It has a concave notch that allows the base end of the plate to enter,
The yoke replaces the height of the front end side of the first upright plate portion with the height of the bottom of the cutout portion on the front end side of the first upright plate portion, and the peripheral edge on the front end side of the hollow member. An electromagnet for solenoid characterized by being lower than the height of the protruding portion.

  According to the invention described in the above (2), the first standing plate portion which is the standing plate portion closer to the proximal end side of the movable piece of the solenoid that is pivotally supported among the two standing plate portions. On the distal end side, a concave cutout portion into which the proximal end portion of the metal plate of the movable piece of the solenoid can enter is provided. In the yoke, not the height of the first standing plate portion, but the bottom portion of the notch portion on the tip side of the first standing plate portion is lower than the height of the peripheral protrusion on the tip side of the hollow member. Therefore, when the movable piece of the solenoid is not attracted, the base end side portion of the metal plate of the movable piece can be disposed in the notch portion on the distal end side of the first standing plate portion of the yoke, and the coil energization Thus, the magnetism during the formation of the magnetic circuit can be efficiently passed from the yoke to the metal plate of the movable piece, and the attraction force at the start (at the start of suction of the movable piece) can be improved. In addition, in the suction state of the movable piece, a gap can be formed between the base end side of the movable piece and the notch portion of the first standing plate portion, and when the coil is de-energized, the gap causes magnetic The circuit can be cut off, and the attractive force due to residual magnetism can be extremely reduced.

(3) In the electromagnet for solenoid according to (1) or (2),
Of the two standing plate portions, on the distal end side of the second standing plate portion, which is the standing plate portion closer to the distal end side opposite to the proximal end side where the movable piece of the solenoid is pivotally supported. The solenoid movable piece has a concave cutout portion into which the distal end side opposite to the base end side of the metal plate can enter,
The yoke replaces the height of the front end side of the second upright plate portion with the bottom height of the notch portion on the front end side of the second upright plate portion, and the peripheral edge on the front end side of the hollow member. An electromagnet for solenoid characterized by being lower than the height of the protruding portion.

  According to invention of said (3), it is a standing board part near the front end side on the opposite side to the base end side by which the movable piece of a solenoid is axially supported among both standing board parts. On the distal end side of the second erected plate portion, a concave cutout portion into which a distal end side portion opposite to the base end side of the metal plate of the movable piece of the solenoid can enter is provided. In the yoke, the bottom height of the notch portion on the tip side of the second standing plate portion is lower than the height of the peripheral projection portion on the tip side of the hollow member, not the height on the tip side of the second standing plate portion. Therefore, when the movable piece of the solenoid is in the suction state, the tip side portion of the metal plate of the movable piece can be sucked into the notch portion on the tip side of the second upright plate portion of the yoke. The magnetism at the time of magnetic circuit formation can be efficiently passed from the yoke to the metal plate of the movable piece, and the attractive force of the movable piece in the attracted state can be improved. Moreover, in the suction state of the movable piece, a gap can be formed between the distal end side of the movable piece and the notch portion of the second standing plate portion, and when the coil is de-energized, this gap causes the magnetic circuit Can be cut off, and the attractive force due to residual magnetism can be made extremely low.

  The present specification also discloses the invention relating to the solenoid as follows.

(4) In the solenoid according to (B0) ,
The abutted portion is a peripheral protruding portion that protrudes at least at the peripheral portion on the distal end side of the hollow member from the surface on the distal end side of the fixed iron core.

  According to the invention as described in said (4), the to-be-contacted part is made into the peripheral protrusion part protruded rather than the surface at the front end side of a fixed iron core at least at the peripheral part at the front end side of a hollow member. The height of the tip side of both the standing plate portions of the yoke is set lower than the height of the peripheral protrusion on the tip side of the hollow member.

  Therefore, in the case of a solenoid having such a solenoid electromagnet, when the coil is energized, the movable piece of the solenoid is attracted to the fixed iron core, and this movable piece comes into contact with the peripheral protrusion on the distal end side of the hollow member. However, the movable piece does not directly contact the fixed iron core and both standing plate parts, but the movable piece has a predetermined gap with respect to each of the fixed iron core and both standing plate parts. Since the suction is performed in a vacant state, the gap can be realized with the manufacturing accuracy of the yoke plate, and the gap adjustment work of adjusting the gap with a positioning member separate from the solenoid as in the conventional example. The problem that it can be made unnecessary and the mounting accuracy varies can be solved.

  Further, since the yoke is provided with the compatible installation plate portion, when the coil is energized, the first magnetic circuit through which the magnetism passes through the fixed iron core, one upright plate portion and the movable piece, and the fixed iron core and the other upright plate A second magnetic circuit through which magnetism passes through the part and the movable piece can be formed, that is, two annular magnetic circuits can be formed, and the attractive force can be increased. That is, another magnetic circuit can be formed as compared with the conventional one-shaped magnetic circuit, and the attractive force can be increased by the newly formed magnetic circuit. Further, since the movable piece is attracted with a predetermined gap between each of the fixed iron core and both standing plate parts, when the coil is not energized, the magnetic circuit is cut off by the gap and the residual Magnetic attraction force can be extremely reduced, only the attraction force can be increased, and the attraction force can be increased efficiently, with a force stronger than the increased residual magnetic attraction force as in the conventional example. A return spring for returning the movable piece to forcibly separate it can be made unnecessary.

  As a result, it is possible to provide a solenoid capable of eliminating the complexity of adjusting the gap between the movable piece and the electromagnet and efficiently increasing the attractive force.

  In addition, when the coil is energized, the movable piece of the solenoid is attracted to the fixed iron core, and this movable piece comes into contact with the peripheral protrusion on the distal end side of the hollow member. Instead of directly contacting the plate portion, the gap between the fixed iron core and the both standing plate portions is provided, so that it is possible to reduce the permanent magnetization of the movable piece.

  Furthermore, since the abutted portion is a peripheral protrusion that protrudes from the front end surface of the fixed iron core at least at the peripheral portion on the front end side of the hollow member, the outer peripheral side of the hollow member is separate from the hollow member. Since there is no need to provide a dedicated contact portion, the space merit is high and the heat dissipation is not deteriorated.

(5) In the solenoid according to (4),
The movable piece is pivotally supported on the distal end side of the first standing plate portion that is one of the standing plate portions of the both standing plate portions, and the distal end side is Displacement between a suction state approaching the distal end side of the second standing plate portion, which is the other standing plate portion of the both standing plate portions, and a non-suction state that is further away from the suction state Solenoid characterized by being capable.

  According to the invention described in (5) above, the movable piece is pivotally supported on the distal end side of the first standing plate portion whose base end side is one of the both standing plate portions. And the front end side is closer to the front end side of the second erecting plate portion, which is the other erecting plate portion of the both erecting plate portions, and in a state separated from the suction state. It can be displaced to a certain non-suction state. Therefore, even in a solenoid in which the base end side of the movable piece is a rotating shaft and the distal end side of the movable piece is separated from the distal end side of the second standing plate portion (non-suction state: one-side open state) The complexity of adjusting the gap between the electromagnet and the electromagnet can be eliminated, and the attractive force can be increased efficiently.

(6) In the solenoid according to (5),
The first upright plate portion includes, on its distal end side, a concave cutout portion into which a proximal end portion of a metal plate provided on the movable piece can enter,
The yoke replaces the height of the front end side of the first upright plate portion with the height of the bottom of the cutout portion on the front end side of the first upright plate portion, and the peripheral edge on the front end side of the hollow member. A solenoid characterized by being lower than the height of the protrusion.

  According to the invention as described in said (6), the 1st standing board part is equipped with the concave-shaped notch part which can approach the base end side part of the metal plate provided in the movable piece in the front end side. ing. Instead of the height of the first standing plate portion on the tip side, the yoke has a bottom height of the notch portion on the tip side of the first standing plate portion higher than the height of the peripheral protrusion on the tip side of the hollow member. Since the movable piece of the solenoid is in a non-suction state, the base end side portion of the metal plate of the movable piece can be disposed in the notch portion on the distal end side of the first standing plate portion of the yoke. The magnetism at the time of magnetic circuit formation by energization can be efficiently passed from the yoke to the metal plate of the movable piece, and the attraction force at the start (at the start of suction of the movable piece) can be improved. In addition, in the suction state of the movable piece, a gap can be formed between the base end side of the movable piece and the notch portion of the first standing plate portion, and when the coil is de-energized, the gap causes magnetic The circuit can be cut off, and the attractive force due to residual magnetism can be extremely reduced.

(7) In the solenoid according to (5) or (6),
The second upright plate portion includes a concave cutout portion on a distal end side thereof, into which a distal end side portion opposite to a proximal end side of a metal plate provided in the movable piece can enter,
The yoke replaces the height of the front end side of the second upright plate portion with the bottom height of the notch portion on the front end side of the second upright plate portion, and the peripheral edge on the front end side of the hollow member. A solenoid characterized by being lower than the height of the protrusion.

  According to the invention as described in said (7), the 2nd standing board part is a recessed part into which the front end side part on the opposite side to the base end side of the metal plate provided in the movable piece can approach at the front end side. It has a notch in the shape. In the yoke, the bottom height of the notch portion on the tip side of the second standing plate portion is lower than the height of the peripheral projection portion on the tip side of the hollow member, not the height on the tip side of the second standing plate portion. Therefore, when the movable piece of the solenoid is in the suction state, the tip side portion of the metal plate of the movable piece can be sucked into the notch portion on the tip side of the second upright plate portion of the yoke. The magnetism at the time of magnetic circuit formation can be efficiently passed from the yoke to the metal plate of the movable piece, and the attractive force of the movable piece in the attracted state can be improved. Moreover, in the suction state of the movable piece, a gap can be formed between the distal end side of the movable piece and the notch portion of the second standing plate portion, and when the coil is de-energized, this gap causes the magnetic circuit Can be cut off, and the attractive force due to residual magnetism can be made extremely low.

  According to the invention described in (8) above, the movable piece is pivotally supported on the distal end side of the first standing plate portion whose base end side is one of the both standing plate portions. And the front end side is closer to the front end side of the second erecting plate portion, which is the other erecting plate portion of the both erecting plate portions, and in a state separated from the suction state. It can be displaced to a certain non-suction state. The nonmagnetic urging means is provided on the first standing plate portion and urges the base end side of the movable piece. Therefore, when the coil is not energized, naturally, a magnetic circuit passing through the fixed iron core, the yoke, and the movable piece is not formed, so that an attractive force for attracting the movable piece toward the fixed iron core is not generated, and the biasing means Since the base end side of the movable piece is only pulled toward the first standing plate part, the base end side of the movable piece is used as a rotation shaft, and the tip side of this movable piece is from the tip side of the second stand plate part. It will be in a separated state (non-suction state: single-open state). Even when the movable piece is in an open state (non-attraction state), the tip side of the first standing plate and the base end side of the movable piece are in contact with each other. Since the magnetism can be passed through the contact location, a suction force for attracting the movable piece at the start of energization of the coil can be ensured, and the suction can be suitably performed.

(9) In the solenoid according to any one of (5) to (7),
A solenoid comprising a biasing means for biasing the base end side of the movable piece via a non-magnetic member on the first standing plate portion.

And the front end side is closer to the front end side of the second erecting plate portion, which is the other erecting plate portion of the both erecting plate portions, and in a state separated from the suction state. It can be displaced to a certain non-suction state. The urging means is provided on the first standing plate portion via the nonmagnetic member, and urges the proximal end side of the movable piece. Therefore, when the coil is not energized, naturally, a magnetic circuit passing through the fixed iron core, the yoke, and the movable piece is not formed, so that an attractive force for attracting the movable piece toward the fixed iron core is not generated, and the biasing means Since the base end side of the movable piece is only pulled toward the first standing plate part, the base end side of the movable piece is used as a rotation shaft, and the tip side of this movable piece is from the tip side of the second stand plate part. It will be in a separated state (non-suction state: single-open state). Even when the movable piece is in an open state (non-attraction state), the tip side of the first standing plate and the base end side of the movable piece are in contact with each other. Since the magnetism can be passed through the contact location, a suction force for attracting the movable piece at the start of energization of the coil can be ensured, and the suction can be suitably performed.

(10) In the solenoid according to any one of (5) to (9),
The movable piece is provided with an extending portion that bends and extends toward the second standing plate portion on the distal end side thereof,
The solenoid is characterized in that the extension portion is not in contact with the second standing plate portion even in the suction state of the movable piece.

  According to the invention described in (10) above, the movable piece includes the extending portion that is bent and extended toward the second standing plate portion on the distal end side thereof. Further, the extending portion is not in contact with the second standing plate portion even in the suction state of the movable piece. Therefore, when the coil is not energized, the distal end side of the movable piece is separated from the distal end side of the second standing plate portion (non-suction state: single-open state). 2 Since there is an extended part that bends and extends toward the standing plate part, the extension part on the tip side of the movable piece is located close to the second standing plate part, so that only the part that is near The suction power can be increased. In the suction state of the movable piece, the movable piece is sucked in a state where a predetermined gap is left between each of the fixed iron core and both of the standing plate portions, and the extending portion is sucked by the movable piece. Even in the state, since it is not in contact with the second standing plate portion, when the coil is de-energized, the magnetic circuit is cut off by the gap, and the attractive force due to the residual magnetism can be extremely reduced. .

  The present specification also discloses an invention relating to the following gaming machines.

(11) In the gaming machine according to (C0) ,
The abutted portion is a peripheral protruding portion that protrudes at least at the peripheral portion on the distal end side of the hollow member from the surface on the distal end side of the fixed iron core.

  According to the invention described in (11) above, as explained in the operation and effect of (4) above, the complexity of adjusting the gap between the movable piece and the electromagnet can be eliminated, and the attractive force can be increased efficiently. Can do. In other words, the reliability of the displacement movement of the movable piece is improved, and the solenoid with improved suction force of the movable piece is adopted, so the problems caused by the conventional solenoid can be reduced and the game reliability is improved. A gaming machine that can be provided can be provided.

  Furthermore, since the abutted portion is a peripheral protrusion that protrudes from the front end surface of the fixed iron core at least at the peripheral portion on the front end side of the hollow member, the outer peripheral side of the hollow member is separate from the hollow member. Since there is no need to provide a dedicated contact portion, the space merit is high and the heat dissipation is not deteriorated.

In addition, the container main body is provided with a pivot support unit that pivotally supports the proximal end side of the movable piece at a location near the distal end side of the first standing plate portion. Therefore, even if the base end side of the movable piece is not pivotally supported by the first standing plate portion of the yoke, but the base end side of the movable piece is pivotally supported by the container body, the above-described (4) The same effect as (10) can be obtained.

  In addition, the conventional solenoid is a type in which the yoke and the movable piece are always in contact with each other, and wear occurs at the contact point between the yoke and the movable piece for each operation of the movable piece, thereby extending the life of the solenoid. Although not possible, in the invention described in (13), the container main body is provided with a pivot support means for pivotally supporting the proximal end side of the movable piece in the vicinity of the distal end side of the first standing plate portion. Since there is no contact between the yoke and the movable piece, and no wear occurs at the contact as described above, the life of the solenoid can be extended.

(14) In the gaming machine according to (13),
The container body is arranged at a predetermined location inside the solenoid electromagnet so that the front end side of the fixed iron core faces downward.
The container body further has a horizontal or substantially horizontal posture in the suction state, and in a non-suction state, the distal end side of the movable piece is spaced downward by a predetermined interval with the base end side of the movable piece as an axis. A gaming machine comprising stopping means for stopping in an oblique posture state.

  According to the invention described in (14) above, the container main body is arranged with a solenoid electromagnet at a predetermined position inside thereof such that the front end side of the fixed iron core faces downward.

Is done. The return button 122 is operated when requesting the return of a card or the like inserted into the card unit. The frequency display unit 123 displays remaining amount information such as a card. It should be noted that the ball rental operation unit 120 is not necessary for a pachinko machine in which game balls are lent directly to the upper plate from a ball lending device or the like without using a card unit, that is, a so-called cash machine. Therefore, a decorative seal or the like is attached to the installation portion of the ball rental operation unit 120. Thereby, the common use of the lending operation unit of the pachinko machine using the card unit and the cash machine can be achieved.

  As shown in FIG. 2, the game board 30 is made of a rectangular plywood, and its peripheral portion is attached in contact with the back side of a resin base (not shown) of the inner frame 12. A gaming area 30a, which is a substantially central portion on the front side of the front side 30, is exposed to the front side of the inner frame 12 through the resin-based substantially circular window portion 101 (glass plate 137) shown in FIG.

  Next, the configuration of the game board 30 will be described with reference to FIG. The game board 30 includes a general winning port 31, a variable winning device 32, first starting ports 33a and 33b (for example, operation chucker), a second starting port 34 (for example, a through gate), a variable display unit 35, and the like.

As described above, the first start port 33a on the upper side is provided with an operation port switch (passage detection switch), and a ball entering the first start port 33a is detected by the operation port switch. It is like that. Further, an operating port switch (passage detection switch) is also provided in the second starting port 33b on the lower side, and a ball entering the second starting port 33b is detected by the operating port switch. . That is, in either case of entering a game ball into the first start port 33a or entering a game ball into the second start port 33b, it is still a start prize.

  In addition, as shown in FIG. 2, the game board 30 is provided with an out port 36, and game balls that have not entered the various winning devices or the like pass through the out port 36 in a ball discharge path (not shown). You will be guided to the direction. A number of nails are planted on the game board 30 in order to appropriately disperse and adjust the falling direction of the game balls, and various members (acts) such as the windmill 37 are arranged.

  The variable display device unit 35 includes a first symbol display device 40 for variably displaying a first symbol (for example, a special symbol) as identification information, triggered by winning in the first start ports 33a and 33b, and a second start. With the passage of the mouth 34 as a trigger, the second symbol display device 41 that variably displays the second symbol (for example, a normal symbol) and the winning of the first start ports 33a and 33b as a trigger, the third symbol (for example, a decorative symbol) ) In a variable manner.

  The first symbol display device 40 includes, for example, a plurality (two in this embodiment) of two-color light emitting type LEDs (light emitting diodes) 40a and 40b, and a hold indicating the number of hold of the variable display on the LEDs 40a and 40b. And a lamp 40c. The LEDs 40a and 40b can emit light in red and blue, for example. The first symbol display device 40 generates a variable display state of the first symbol (in this embodiment, the emission color mode of each LED 40a, 40b) by alternately changing the emission color of each LED 40a, 40b, for example, When both LEDs 40a and 40b stop in a red light emitting state, a probable big hit (specific hit) is indicated, and when both LEDs 40a and 40b stop in a blue light emitting state, a normal big hit (non-specific hit) is indicated, and both LEDs 40a and 40b are mutually connected. When it stops in the light emission state of a different color, it will show off.

  In addition, as this 1st symbol display apparatus 40, you may employ | adopt the single LED of the type which can light-emit at least 3 colors or more, and by performing light emission of each color alternately, the 1st symbol is displayed. When the LED stops in the light emission state of the first color, it shows a probable big hit (specific hit), and when the LED stops in the light emission state of the second color, it usually shows a big hit (non-specific hit) When the LED stops in the light emission state of the third color, it may be indicated that the LED has come off. The first symbol display device 40 described above corresponds to the identification information fluctuation display means in the present invention.

  The second symbol display device 41 includes, for example, a display unit 41a on which “○” is drawn for the second symbol, a display unit 41b on which “x” is drawn for the second symbol, and a holding lamp 41c. When the game ball passes through the second starting port 34, for example, the display symbols (ordinary symbols) displayed by the display units 41a and 41b change, and when the change display stops at a predetermined symbol, the lower side One start port 33b is configured to be in an activated state (opened) for a predetermined time. The number of times that the game ball has passed through the second start port 34 is held up to a maximum of 4 times, and the number of times the game ball is held is lit on the hold lamp 41c. The display units 41a and 41b have LEDs (light emitting diodes) inside thereof, and are configured to be variably displayed by switching the light emission of the LEDs (or lighting of the lamps). The second symbol display device 41 described above corresponds to the normal identification information fluctuation display means in the present invention.

  The 3rd symbol display apparatus 42 is comprised, for example with the liquid crystal display device, and the display content is controlled by the display control apparatus 45 mentioned later. On the third symbol display device 42, for example, as shown in FIG. 5 described later, three decorative symbol rows L, M, and R on the left, middle, and right are displayed. Each of the decorative symbol rows L, M, R is composed of a plurality of decorative symbols, and these decorative symbols are variably displayed on the third symbol display device 42 so as to be scrolled for each of the decorative symbol rows L, M, R. It has become so. In the present embodiment, the third symbol display device 42 (liquid crystal display device) includes, for example, a large 9.3 inch size liquid crystal display. The variable display device unit 35 is provided with a center frame 47 so as to surround the third symbol display device 42. The above-described third symbol display device 42 corresponds to decoration identification information (design) variation display means in the present invention, and the above-described display control device 45 corresponds to display control means in the present invention.

  As shown in FIG. 2, the variable winning device 32 is normally in a closed state in which a game ball cannot be won or difficult to win, and is in an open state in which a game ball is easy to win in the case of a big win and a normal closed state. It is operated repeatedly. As described above, a state in which the variable winning device 32 is repeatedly operated in an open state and a normal closed state in the case of a big win is called a special game state (for example, a big win state). Since the ball enters (wins) and a lot of game balls are paid out for the winning, the game state is advantageous to the player.

  More specifically, when a game ball wins the first start opening 33a, 33b, the two LEDs 40a, 40b of the first symbol display device 40 are displayed in a variable manner, and the display of the LEDs 40a, 40b after the change stop is preset. The special gaming state occurs when the combination of the light emission modes is achieved. For example, in the case of a light emitting mode in which both LEDs 40a and 40b are stopped in a red light emitting state, it indicates that a special gaming state with a probable big hit (specific hit) is won, and both LEDs 40a and 40b are stopped in a blue light emitting state. In the case of the light-emitting mode, it means that the special game state of the big hit (non-specific hit) is normally won, and in the case of the light-emitting mode in which both LEDs 40a and 40b are stopped in the light-emitting states of different colors. (You have lost the special game state).

  The variable winning device 32 is configured such that the large winning opening 32a is in a predetermined open state, and the game ball is likely to win (a big hit state). Specifically, the special winning opening 32a of the variable winning device 32 is repeatedly opened a predetermined number of times (the number of rounds) with the passage of a predetermined time or a predetermined number of winnings in the open state as one round. The number of times that the game ball has passed through the first start ports 33a and 33b is held up to a maximum of 4 times, and the number of times that the game ball is held is lit and displayed by the hold lamp 40c. Note that the hold lamp 40c may be configured such that a hold display is performed on a part of the display screen of the third symbol display device 42.

  Further, as shown in FIG. 2, a rail unit 50 for guiding the game ball launched from the game ball launcher 38 (see FIG. 3) to the upper part of the game board 30 is attached to the game board 30. A game ball launched in accordance with the turning operation of the game ball launch handle 18 is guided to a predetermined game area 30a through a ball guide passage 49 (to be described later) of the rail unit 50. The rail unit 50 is formed of a ring-shaped resin molded product (for example, a molded product added with fluororesin), and has an inner rail 51 and an outer rail 52 that are integrally formed in an inner and outer double. . The inner rail 51 is formed in a substantially annular shape except for about 1/4 of the upper part, and the outer rail 52 is formed so that a part (mainly the left side) faces the inner rail 51. In such a case, a guide rail is constituted by the inner rail 51 and the outer rail 52, and a ball guide passage 49 is formed by a portion (the left portion toward the left) where the rails 51 and 52 are parallel to each other at a predetermined interval. . The ball guide passage 49 is formed in a groove shape having a contact surface with the game board 30, that is, a groove shape in which the front side is opened.

  A return ball preventing member 53 is attached to the tip portion of the inner rail 51 (the upper left portion in FIG. 2). This prevents a situation in which the game ball once guided from the ball guide passage 49 between the inner rail 51 and the outer rail 52 to the upper portion of the game board 30 returns to the ball guide passage 49 again. It has become. Further, a return rubber 54 is attached to the outer rail 52 at a position corresponding to the maximum flight portion of the game ball (upper right portion in FIG. 2: a portion corresponding to the tip portion of the outer rail 52). Therefore, the game ball fired at a predetermined momentum or more hits the return rubber 54 and is bounced back. On the inner surface of the outer rail 52, there is a sliding plate 55 as a long metal strip made of stainless steel to make the flight of the game ball smoother, that is, to reduce the frictional resistance of the game ball. It is attached.

  Further, an arc-shaped flange 56 is formed on the outer peripheral portion of the rail unit 50 so as to project outward from the periphery when viewed from the front. The flange 56 constitutes a mounting surface for the game board 30. When the rail unit 50 is attached to the game board 30, the flange 56 is brought into contact with the game board 30, and in this state, screws or the like are inserted into a plurality of through holes formed in the flange 56. The rail unit 50 is fastened to 30.

  Furthermore, in the present embodiment, the top, bottom, left, and right ends of the rail unit 50 are formed in a substantially straight line (flat) when viewed from the front. That is, the flange 56 is cut off at each of the upper, lower, left and right ends of the rail unit 50 so that the rail diameter can be expanded in a limited area in the pachinko machine 10, that is, the game area 30a on the game board 30 can be expanded. It has become.

  A convex portion 57 is formed at the entrance of the ball guide passage 49 between the inner rail 51 and the outer rail 52 so as to close a part of the ball guide passage 49. The convex portion 57 is provided in a substantially vertical direction from the inner rail 51 to the lower end portion of the rail unit 50, and a foul ball that does not reach the game area 30 a and flows backward in the ball guide passage 49 is provided on the inner frame 12. It plays a role of guiding to a ball passage (not shown). Note that the lower right corner and the lower left corner of the game board 30 are spaces for attaching stickers (eg, S1 and S2 in FIG. 2) and plates such as certificate stamps (for example, serial numbers are described). In order to secure this adhering space, notches 58 and 59 are formed in the flange 56. By sticking a sticker such as a certificate (S1, S2 in FIG. 2) to the lower right corner or the lower left corner of the game board 30, the game board 30 and the certificate can be uniquely defined.

  Next, the game area 30a of the game board 30 will be described. As shown in FIG. 2, the game area 30 a is partitioned into a substantially circular shape by the inner peripheral portion (inner and outer rails) of the rail unit 50. In particular, in the present embodiment, the game area 30 a is partitioned on the board surface of the game board 30. The game area 30a is configured to be much larger than before. In the present embodiment, the distance between the uppermost point of the outer rail 52 and the lower part of the game board 30 is 445 mm (58 mm longer than the conventional product), and is from the extreme left position of the outer rail 52 to the extreme right position of the inner rail 51. The distance is 435 mm (50 mm longer than the conventional product). The distance from the extreme left position of the inner rail 51 to the extreme right position of the inner rail 51 is 418 mm.

  In the present embodiment, the game area 30a is viewed from the front of the pachinko machine 10, and the area of the guide rail that is a parallel part of the inner and outer rails 51 and 52 is excluded from the area surrounded by the inner rail 51 and the outer rail 52. As an area. Accordingly, when the game area 30 a is referred to, the guide rail portion is not included, and therefore the left limit position toward the game area 30 a is specified by the inner rail 51, not by the outer rail 52. Similarly, the right limit position toward the game area 30 a is specified by the inner rail 51. Further, the lower limit position of the game area 30 a is specified by the lower end position of the game board 30. The upper limit position of the game area 30 a is specified by the outer rail 52.

  Therefore, in the present embodiment, the width (maximum width in the left-right direction) of the game area 30a is 418 mm, and the height (maximum width in the vertical direction) of the game area 30a is 445 mm.

  Although detailed disclosure of the drawings is omitted, game balls are supplied to the game ball launcher 38 one by one from the ball outlet on the front frame set 14 side (the ball outlet leading from the most downstream portion of the upper plate 19). .

  Next, the configuration of the back surface of the pachinko machine 10 will be described. As shown in FIG. 3, the pachinko machine 10 is configured such that various control boards are arranged vertically or horizontally on the back surface (actually the back surface of the inner frame 12 and the game board 30) or stacked in front and back. Further, a game ball supply device (payout mechanism portion 352) for supplying game balls, a protective cover made of resin, and the like are attached. In this embodiment, various control boards are divided into two mounting bases to form two control board units, and these control board units are individually attached to the inner frame 12 or the back of the game board 30. ing. In this case, a main control device 261 and a sub control device 262 shown in FIG. 4 to be described later are mounted on one mounting base to form a unit, and a payout control device 311 and a launch control device 312 shown in FIG. 4 to be described later. The power supply device 313 is mounted on the other mounting base to form a unit. Here, for convenience, the former unit is referred to as “first control board unit 201”, and the latter unit is referred to as “second control board unit 202”.

  Further, since the dispensing mechanism 352 and the protective cover are also integrated as one unit, and the resin portion is generally referred to as a back pack, the unit is referred to as a “back pack unit 203” here. The detailed configuration of each unit 201 to 203 will be described later.

  The first control board unit 201, the second control board unit 202, and the back pack unit 203 are configured so that they can be attached and detached without using any tools or the like in units of units. It is provided and can be opened and closed with respect to the inner frame 12 or the back surface of the game board 30. This is also a device for making it possible to easily check a hidden configuration or the like even if the units 201 to 203 and other configurations are arranged one behind the other.

  In addition, on the back surface of the game board 30, a winning detection mechanism for detecting the passage of game balls such as various winning holes is provided. Specifically, a prize opening switch is provided at a position corresponding to the general prize opening 31 on the front side of the game board 30, and the variable prize winning device 32 is provided with a count switch. The count switch is a switch for counting winning balls. In addition, operation port switches are provided at positions corresponding to the first start ports 33a and 33b, respectively, and the entry of game balls into the first start ports 33a and 33b is detected by the operation port switches. A gate switch is provided at a position corresponding to the second starting port 34, and the passage of the game ball to the second starting port 34 is detected by the operating port switch. ing. The operating port switch described above corresponds to the winning detection means in the present invention.

  The prize opening switch and the gate switch are connected to a board connection board (not shown) through electrical wiring (not shown), and this board connection board is further connected to a main control board 261a (see FIG. 4) in a main controller 261 described later. ing. Further, the count switch is connected to a large winning opening relay terminal board (not shown), and this large winning opening relay terminal board (not shown) is also connected to the main control board 261a. On the other hand, the operation port switch is directly connected to the main control board 261a without going through the relay board.

  Although not shown in the drawings, the variable prize winning device 32 is provided with a big prize opening solenoid for opening the big prize opening 32a, and the lower first start opening 33b is used for opening the electric accessory. Is provided.

  The detection results detected by the winning detection mechanism are taken into a main control board 261a in a main control device 261, which will be described later, and the main control board 261a issues a payout command (a game ball of each game ball) according to the winning situation each time. The number of payouts) is transmitted to the payout control board 311a. Then, a predetermined number of game balls are paid out by the output of the payout control board 311a. In such a case, a conventional method (so-called evidence ball method) in which game balls won in various winning openings are once collected in a winning ball processing device and paid out after the winning ball processing device confirms the presence of winning balls one by one in order. Unlike the above, in the pachinko machine 10 according to the present embodiment, the winning of a game ball is electrically detected for each winning opening and the payout is immediately made (that is, the winning ball processing apparatus is abolished in the pachinko machine 10). is doing). Therefore, even if there are a lot of game balls to be paid out, the payout can be carried out quickly. However, the conventional “evidence ball system” may be applied to the present invention.

  The first control board unit 201 has a substantially L-shaped mounting base (not shown), and the main control device 261 and the sub control device 262 are mounted on the mounting base.

The substrate box 263 includes a substantially rectangular parallelepiped box base and a box cover that covers the opening of the box base. The box base and the box cover are connected by a sealing unit (sealing means) so that they cannot be opened, and the substrate box 263 is thus sealed.

  Any configuration can be applied to the sealing unit as the sealing means as long as it connects the box base and the box cover so that they cannot be opened. In this embodiment, for example, five sealing members are connected. The box base and the box cover are connected so that they cannot be opened by inserting a locking claw into the long hole of the sealing member. Sealing processing by the sealing unit prevents unauthorized opening after the sealing, and makes it possible to detect such a situation quickly and easily even if unauthorized opening is performed. Even after that, it is possible to perform the opening / sealing process again. That is, the sealing process is performed by inserting the locking claw into the long hole of at least one sealing member among the five sealing members constituting the sealing unit (not shown). And when opening the board | substrate box 263 by the malfunction of the accommodated main control board | substrate 261a etc., the connection of the sealing member in which the latching claw was inserted, and another sealing member is cut | disconnected. Thereafter, when the sealing process is performed again, the locking claws are inserted into the long holes of the other sealing members. If the history of opening the substrate box 263 is left in the substrate box 263, it can be easily found that the unauthorized opening has been performed by looking at the substrate box 263.

  Further, the sub control device 262, for example, in accordance with an instruction from the main control board 261a in the main control device 261, controls the voice and lamp display and the control of the display control device 45, the other ROM 552, RAM 553, bus line 554, A sub-control board 262a including an input / output port 555 and the like is provided, and the sub-control board 262a is housed in a board box (not shown) made of a transparent resin material or the like.

  Each of the dispensing mechanisms 352 from the tank 355 to the dispensing passage (not shown) is formed of a conductive resin material (for example, conductive polycarbonate resin) and grounded at a part thereof. Thereby, generation | occurrence | production of the noise by charging of a game ball is suppressed.

  As shown in FIG. 3, an inner frame open detection switch 388 for detecting that the inner frame 12 is opened with respect to the outer frame 11 is provided on the upper right side of the inner frame 12. When the inner frame 12 is opened, it is outputted from the inner frame open detection switch 388 to the computer for the hall (in the pachinko parlor).

  Next, the electrical configuration of the pachinko machine 10 will be described with reference to FIG. The pachinko machine 10 includes a main control device 261, a payout control device 311, a launch control device 312, a sub control device 262, a display control device 45, a power supply device 313, and the like. In the following, these devices will be described in detail individually.

  The main control device 261 of the pachinko machine 10 is equipped with a CPU 501 as a one-chip microcomputer that is an arithmetic device. The CPU 501 includes a ROM 502 that stores various control programs executed by the CPU 501 and fixed value data, and a memory that temporarily stores various data when the control program stored in the ROM 502 is executed. A RAM 503 and various circuits such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are incorporated.

  The RAM 503 has a configuration in which data can be retained (backed up) by being supplied with a backup voltage from the power supply device 313 even after the pachinko machine 10 is turned off. The RAM 503 temporarily stores various data and the like. It has a memory and area.

  That is, when the power is cut off due to the occurrence of a power failure or the like, the CPU 501 of the main control device 261 executes the normal processing up to the end, so that the RAM 503 is when the power is turned off (including when a power failure occurs, and so on). It is only necessary to store and hold the contents of the counter buffer and the holding ball storage area, and the state of the pachinko machine 10 can be restored to the state before the power is turned off when the power is turned on again. Specifically, the RAM 503 has a dedicated backup area for storing values of registers, I / O, and the like for game information during normal processing when the power is turned off (including when a power failure occurs). There is no need to provide it. The N501 terminal (non-maskable interrupt terminal) of the CPU 501 is configured to receive a power failure signal S1 output from a power failure monitoring circuit 542, which will be described later, when a power failure occurs due to the occurrence of a power failure or the like. Due to the occurrence, the power failure process (NMI interrupt process) is immediately executed.

  An input / output port 505 is connected to the CPU 501 incorporating the ROM 502 and RAM 503 via a bus line 504 including an address bus and a data bus. The input / output port 505 includes a RAM erasing switch circuit 543, a payout control device 311, a firing control device 312, a sub control device 262, a first symbol display device 40, a second symbol display device 41, and other switches not shown.

The main controller 261 also has a function of controlling the first symbol variation display on the first symbol display device 40 and the second symbol variation display on the second symbol display device 41.

  The payout control device 311 controls payout of prize balls and rental balls by a payout motor 358a. The CPU 511 that is an arithmetic unit includes a ROM 512 that stores a control program executed by the CPU 511, fixed value data, and the like, and a RAM 513 that is used as a work memory or the like.

  The RAM 513 of the payout control device 311 is configured to hold (backup) data by supplying a backup voltage from the power supply device 313 even after the pachinko machine 10 is turned off, like the RAM 503 of the main control device 261 described above. The RAM 513 includes a memory and an area for temporarily storing various data.

  The RAM 513 stores and holds information related to the state when the power is turned off in order to return the state of the pachinko machine 10 to the state before the power is turned off when the power is turned off due to a power failure or the like. In other words, the storage of the RAM 513 is executed when the power is turned off by the NMI interrupt process and the second half of the payout control process, and the storage information stored in the RAM 513 is restored in the power recovery process when the power is turned on. .

  An input / output port 515 is connected to the CPU 511 incorporating the ROM 512 and the RAM 513 through a bus line 514 including an address bus and a data bus. Main controller 261, launch controller 312 and payout motor 358a are connected to input / output port 515, respectively.

  The pachinko machine 10 according to the present embodiment is configured to fire about 100 gaming balls supplied from the upper plate 19 one by one. That is, in the ball feeding operation of the game ball by the launch unit 410 and the game ball hitting operation by the launch solenoid 420, about 100 game balls are fired one by one. That is, as soon as the game ball is fed by the launch unit 410, the launch solenoid 420 fires the ball at high speed. Further, as described above, the launch control device 312 has the touch detection signal S5 from the game ball launch handle 18, the launch maintenance signal S6 from the launch stop switch S6, and the payout control device 311 as shown in FIG.

Thus, it enters the entrance 412 of the launch unit 410. As shown in FIG. 9, the movable piece 450 of the ball feed solenoid 430 is away from the fixed iron core 441, and the leading game ball that has entered the inlet portion 412 abuts on the distal end side of the movable piece 450. It is in a stopped state, and the second gaming ball is subsequently stopped after this leading gaming ball. Further, when this state is viewed from the front side of the pachinko machine 10, it is as shown in FIG. That is, as shown in FIG. 11A, the coil 443 of the ball feed solenoid 430 is de-energized, and the suction force to the fixed iron core 441 is not generated. It is in a state of being separated from the fixed iron core 441, and the leading game ball is in contact with and stopped at the tip side of the movable piece 450, and is taken along the line AA shown in FIG. As shown in FIG. 11 (b) as a cross-sectional view, it can be seen that the first and second game balls are stopped in a state where they enter the inlet portion 412.

  Subsequently, as shown in FIG. 12A, the coil 443 of the ball feed solenoid 430 is energized to generate a suction force to the fixed iron core 441. Therefore, the movable piece 450 of the ball feed solenoid 430 is fixed. It will be in the state attracted | sucked to the iron core 441. FIG. At this time, the leading game ball is taken into the recess 453 on the distal end side of the movable piece 450. As shown in FIG. 12 (b), which is a cross-sectional view taken along the line AA shown in FIG. 12 (a), it can be seen that the first and second game balls are stopped in a state of further entering.

  Subsequently, as shown in FIG. 13A, the coil 443 of the ball feed solenoid 430 is de-energized to extinguish the adsorption force to the fixed iron core 441. Therefore, the movable piece 450 of the ball feed solenoid 430 is removed. However, it will be in the state spaced apart from the fixed iron core 441 with the dead weight. At this time, the leading game ball taken into the concave portion 453 on the distal end side of the movable piece 450 is output to the outlet portion 413, and the game ball output from the outlet portion 413 is positioned on the proximal end side of the firing rail portion 400. It will be dressed up. As shown in FIG. 13B, which is a cross-sectional view taken along the line AA shown in FIG. 13A, the game ball output from the outlet portion 413 is located on the proximal end side of the firing rail portion 400. At the entrance 412 of the launch unit 410, the second game ball becomes the top game ball and is in contact with and stopped at the tip side of the movable piece 450. It can be seen that the game balls are stopped.

  As described above, the movable piece 450 suppresses the output of the game ball from the inlet portion 412 to the outlet portion 413 when the movable piece 450 is in the non-suction state, and when the movable piece 450 enters the suction state, the exit of the game ball from the inlet portion 412 is suppressed. It is configured to allow output to the unit 413. In other words, the movable piece 450 stops the game ball from the inlet portion 412 on the tip side when it is in the non-sucking state, and prevents it from being output to the outlet portion 413. It is configured such that the game ball is captured by the concave portion 453 on the tip end side and the game ball in the concave portion 453 is output to the outlet portion 413 when the non-suction state is reached.

As shown in FIGS. 16A and 16B, the fixed iron core 441 has a cylindrical shape with a head, and a disk-shaped head 441 a formed on the side facing the movable piece 450. The diameter of the body part 441b is smaller than the diameter of the body part 441b, and an insertion part 441c smaller than the diameter of the body part 441b is provided at the base end part. As shown in FIGS. 16C and 16D, the bobbin 442 includes a circular hollow portion in a cross-sectional view into which the fixed iron core 441 is inserted, and a coil 443 is wound around the outer peripheral side thereof. .

  As shown in FIG. 16 (f), the yoke 444 has a conical shape (recessed shape) when viewed from the back (when viewed from the front, the yoke 444 has a conical shape as when viewed from the back). When viewed from the bottom as shown in e) (when viewed from the opening side), a fixed receiver 444e into which the insertion portion 441c on the proximal end side of the fixed iron core 441 inserted into the bobbin 442 is inserted is formed on the fixed surface portion 444a. When viewed from the side as shown in FIG. 16 (e), for example, a conical notch 444d is formed on the tip side of the compatible plate portions 444b and 444c.

  As shown in FIGS. 16E to 16G, the yoke 444 has a screw hole into which a fixing screw is inserted so as to be attached to a container portion (not shown) of the container body 411. When viewed from the side, an L-shaped attachment portion 444f is provided. That is, by inserting a screw into the screw hole of the attachment portion 444f of the yoke 444 and screwing the screw into the container portion (not shown) of the container body 411, the yoke 444, that is, the solenoid electromagnet 440 is fastened to the container body 411. It has come to be.

  Here, the suction operation of the ball feed solenoid 430 in the launch unit 410 in the pachinko machine 10 of the present embodiment will be described below with reference to FIG. FIG. 18A is a diagram showing a magnetic circuit when the ball feed solenoid 430 of this embodiment is attracted, and FIG. 18B shows a magnetic circuit when the ball feed solenoid 430 of this embodiment is attracted. FIG. 18 (c) is a diagram showing a magnetic circuit at the time of attraction of another ball feed solenoid 490 which is inferior to the present embodiment, and FIG. 18 (d) is shown in FIG. 18 (c). It is a figure which shows the magnetic circuit at the time of adsorption | suction of the ball feed solenoid 490. FIG.

  As shown in FIG. 18A, when the ball feed solenoid 430 of this embodiment is attracted, the coil 443 of the ball feed solenoid 430 is energized, and in addition to the magnetic circuit shown by the solid line, another new one shown by the broken line is shown. Another magnetic circuit (additional magnetic circuit) is formed. In a ball feed solenoid 490 different from the present embodiment shown in FIG. 18C, only a magnetic circuit indicated by a solid line is formed. That is, in the ball feed solenoid 430 of the present embodiment, another new magnetic circuit (additional magnetic circuit) indicated by a broken line is formed, and therefore compared with the ball feed solenoid 490 of FIG. The suction power is increasing (up).

  As shown in FIG. 18B, the energization of the coil 443 is maintained, and when the movable piece 450 is in the suction state, the ball feed solenoid 430 of this embodiment includes both the standing plate portions 444b, There is a non-contact gap between 444c and the metal plate 454 of the movable piece 450 and between the fixed iron core 441 and the metal plate 454 of the movable piece 450. The circuit is formed without any problem, and the suction state of the metal plate 454 of the movable piece 450 to the fixed iron core 441 can be favorably maintained.

  By the way, when the energization to the coil 443 is stopped and de-energized, the ball feed solenoid 430 of the present embodiment, as described above, has both the standing plate portions 444b and 444c and the metal of the movable piece 450. Since gaps are formed in a non-contact manner between the plate 454 and between the fixed iron core 441 and the metal plate 454 of the movable piece 450, these gaps serve as the breaking points SP of the magnetic circuit, and residual magnetism. Therefore, the movable piece 450 can be quickly separated from the fixed iron core 441. That is, in the ball feed solenoid 490 shown in FIG. 18D, the tip side of the yoke 444 and the metal plate 454 of the movable piece 450 are in contact with each other in a state where the metal plate 454 of the movable piece 450 is attracted to the fixed iron core 441. Therefore, even if the coil 443 is not energized, there is a problem that the movable piece 450 is not separated from the fixed iron core 441 due to an attractive force due to residual magnetism, or is difficult to leave. That is, in the ball feed solenoid 430 of the present embodiment, both magnetic circuits can be cut by a gap (two blocking points SP) between both the standing plates 444b and 444c and the metal plate 454 of the movable piece 450. Therefore, as compared with the ball feed solenoid 490 of FIG. 18D, the attractive force due to the residual magnetism can be extremely reduced.

  As described above, according to the solenoid electromagnet 440 of the first embodiment, the fixed iron core 441, the non-magnetic bobbin 442 having the hollow portion into which the fixed iron core 441 is fitted, and the outer periphery of the bobbin 442 A coil 443 wound around the axis of the fixed iron core 441 and a base end side of the fixed iron core 441 fitted in a hollow portion of the bobbin 442 around which the coil 443 is wound are fixed. A solenoid electromagnet 440 including a yoke 444 through which the bobbin 442 passes is provided with a peripheral protrusion 445 that protrudes slightly from the front end surface of the fixed iron core 441 at least at the peripheral end of the bobbin 442. The yoke 444 is fixed. A fixing surface portion 444a having a fixing receiver 444e for fixing the base end side of the iron core 441, and the fixing surface portion 444a in a state of being viewed from the side. Both end sides of the portion 444a are provided with both of the standing plate portions 444b and 444c erected on the side where the fixed iron core 441 exists, and the base end on which the movable piece 450 is pivotally supported among the both standing plate portions 444b and 444c. On the distal end side of the first standing plate portion 444b, which is the standing plate portion closer to the side, is provided with a concave cutout portion 444d into which the proximal end portion of the metal plate 454 of the movable piece 450 can enter, The base of the metal plate 454 of the movable piece 450 is disposed at the distal end side of the second standing plate portion 444c, which is a standing plate portion closer to the distal end side opposite to the proximal end side on which the movable piece 450 is pivotally supported. A concave notch portion 444d into which the tip side portion opposite to the end side can enter is provided, and the bottom height H1 of the notch portion 444d of the first standing plate portion 444b and the second standing plate portion 444c is set. It is made lower than the height H2 of the peripheral protrusion 445 on the tip side of the bobbin 442.

  Therefore, when such a solenoid electromagnet 440 is employed in the ball feed solenoid 430, the movable piece 450 of the ball feed solenoid 430 is attracted to the fixed iron core 441 by energizing the coil 443. Although it will be in the state contact | abutted to the peripheral protrusion 445 of the front end side of the bobbin 442, the movable piece 450 does not contact the fixed iron core 441 and both standing-up board parts 444b and 444c directly, but the movable piece 450 Since the suction is performed with a predetermined gap between each of the fixed iron core 441 and the both standing plate portions 444b and 444c, the manufacturing accuracy of both the standing plate portions 444b and 444c of the yoke 444 is concerned. A gap can be realized, and the gap adjustment work of adjusting the gap with a positioning member separate from the solenoid as in the conventional example can be made unnecessary. It can be solved the problem varies.

  Further, since the compatible plate portions 444b and 444c are provided in the yoke 444, when the coil 443 is energized, the first magnetic circuit through which the magnetism passes through the fixed iron core 441, the one upright plate portion 444b, and the movable piece 450, The second magnetic circuit through which the magnetism passes can be formed through the fixed iron core 441, the other upright plate portion 444c, and the movable piece 450, that is, two annular magnetic circuits can be formed and attracted. Can increase power. That is, another magnetic circuit can be formed as compared with the conventional one-shaped magnetic circuit, and the attractive force can be increased by the newly formed magnetic circuit. In addition, since the movable piece 450 is sucked with a predetermined gap between each of the fixed iron core 441 and the two standing plate portions 444b and 444c, when the coil 443 is not energized, the gap is caused by the gap. The magnetic circuit is cut off, the attractive force due to residual magnetism can be extremely lowered, only the attractive force can be increased, the attractive force can be increased efficiently, and increased residual magnetism as in the conventional example A return spring that returns the movable piece 450 so as to be forcibly separated by a force stronger than the suction force can be made unnecessary.

  As a result, it is possible to provide a solenoid electromagnet 440 that can eliminate the complexity of adjusting the gap between the movable piece 450 and the electromagnet, and can efficiently increase the attractive force.

  Further, since the peripheral protrusion 445 that protrudes slightly from the front end surface of the fixed iron core 441 is provided at least at the peripheral part on the front end side of the bobbin 442, the bobbin 442 is separated from the outer periphery of the bobbin 442. Since there is no need to provide a dedicated contacted part (a member that is contacted by a non-magnetic material), space merit is high and heat dissipation is not deteriorated.

  When the coil 443 is energized, the movable piece 450 of the ball feed solenoid 430 is attracted to the fixed iron core 441 and the movable piece 450 comes into contact with the peripheral protrusion 445 on the tip side of the bobbin 442. 450 is not in direct contact with the fixed iron core 441 and both standing plate portions 444b and 444c, but is in a state in which a gap is left between the fixed iron core 441 and both standing plate portions 444b and 444c. Therefore, it is possible to reduce the permanent magnetization of the movable piece 450.

  Further, the movable piece 450 is disposed on the distal end side of the first standing plate portion 444b, which is the standing plate portion closer to the proximal end side of the movable piece 450 that is pivotally supported, of both the standing plate portions 444b and 444c. The metal plate 454 includes a notch 444d having a concave shape into which the proximal end portion of the metal plate 454 can enter, and the yoke 444 is not the height of the first standing plate portion 444b but the first standing plate portion 444b. Since the bottom portion height of the notch portion 444d on the distal end side is lower than the height of the peripheral protrusion portion 445 on the distal end side of the bobbin 442, the metal plate 454 of the movable piece 450 is in the non-suction state. The base end side portion can be disposed in the notch 444d on the distal end side of the first standing plate portion 444b of the yoke 444, and the magnetism at the time of forming the magnetic circuit by energization of the coil 443 is transferred from the yoke 444 to the movable piece 450. Efficiently passing through metal plate 454 Can, it is possible to improve the suction force at the start (at start of suction of the movable piece 450). Moreover, in the suction state of the movable piece 450, a gap can be formed between the base end side of the movable piece 450 and the notch 444d of the first standing plate portion 444b, and the coil 443 is deenergized. In this case, the magnetic circuit can be interrupted by this gap, and the attractive force due to residual magnetism can be extremely reduced.

  Of the two standing plate portions 444b and 444c, the second standing plate portion 444c, which is the standing plate portion closer to the distal end side opposite to the base end side on which the movable piece 450 is pivotally supported, is provided. On the distal end side, a concave cutout portion 444d into which a distal end side portion opposite to the proximal end side of the metal plate 454 of the movable piece 450 can enter is provided, and the yoke 444 is a distal end of the second standing plate portion 444c. Since the height of the bottom of the notch 444d on the front end side of the second upright plate portion 444c is lower than the height of the peripheral protrusion 445 on the front end side of the bobbin 442, not the height on the side, the movable piece 450 In the attracted state, the distal end portion of the metal plate 454 of the movable piece 450 can be attracted to the notch portion 444d on the distal end side of the second standing plate portion 444c of the yoke 444, and the magnetic force generated by energizing the coil 443 Magnetization during circuit formation is movable from yoke 444 It can be passed through the metal plate 454 of the 450 efficiently, thereby improving the suction force of the suction state of the movable piece 450. Moreover, in the suction state of the movable piece 450, a gap can be formed between the distal end side of the movable piece 450 and the cutout portion 444d of the second standing plate portion 444c, and when the coil 443 is de-energized. The magnetic circuit can be interrupted by this gap, and the attractive force due to residual magnetism can be extremely reduced.

  Further, according to the ball feed solenoid 430 of this embodiment, since the solenoid electromagnet 440 of this embodiment is provided, as described above, the complexity of adjusting the gap between the movable piece 450 and the solenoid electromagnet 440 is eliminated. The attractive force can be improved, and the attractive force due to residual magnetism can be extremely reduced.

  Further, according to the pachinko machine 10 of the present embodiment, since the ball feed solenoid 430 of the present embodiment is provided, as described above, the complexity of adjusting the gap between the movable piece 450 and the solenoid electromagnet 440 can be eliminated. The attractive force can be improved, and the attractive force due to residual magnetism can be extremely reduced. That is, since the reliability of the displacement operation of the movable piece 450 is improved and the ball feed solenoid 430 in which the suction force of the movable piece 450 is improved is adopted, problems caused by the conventional solenoid can be reduced, and the game A gaming machine capable of improving the reliability of the game can be provided.

  Next, the pachinko machine 10 according to the second embodiment will be described with reference to FIG. FIG. 19A is a plan view showing a schematic configuration of the ball feeding solenoid 430A of the second embodiment at the time of non-suction, and FIG. 19B is a side view of the ball feeding solenoid 430A shown in FIG. FIG. 19C is a plan view showing a schematic configuration of the ball feeding solenoid 430A of the second embodiment at the time of suction, and FIG. 19D is a side view of the ball feeding solenoid 430A shown in FIG. 19C. .

  The ball feed solenoid 430A in the second embodiment is different from the first embodiment in that it is applied to a so-called flapper type solenoid. In addition, description is abbreviate | omitted about the content similar to the above-mentioned Example 1, and suppose that the ball | bowl feed solenoid 430A in this Example 2 is demonstrated in detail below.

  As shown in FIG. 19, the ball feed solenoid 430A in the second embodiment is a flapper type solenoid, and the base end side of the movable piece 450 via the non-magnetic member 470 on the first standing plate portion 444b. A spring 471 (coil spring) for biasing is provided. The spring 471 described above corresponds to the biasing means of the present invention.

  In the second embodiment, the spring 471 (coil spring) is used as the biasing means. However, other elastic members may be used as long as the base end side of the movable piece 450 is biased. May be.

  In the ball feed solenoid 430A of the second embodiment, as shown in FIG. 19 (b), the metal plate 454 of the movable piece 450 is in contact with the first standing plate portion 444b of the yoke 444 in the non-suction state. One feature of the second embodiment is that magnetism easily passes through the contact portion in the attracted state.

  Further, the shape of the movable piece 450 shown in FIG. 19 is different from that of the first embodiment described above, but in FIG. 19, it means that the movable piece 450 itself is a metal plate 454. In addition, the locations near the upright plate portions 444b and 444c of the yoke 444 (the increased locations ZK shown in FIG. 19) are greater than those in the first embodiment, and the suction force is increased.

  Here, the suction operation of the ball feed solenoid 430A of the second embodiment will be described below with reference to FIG. FIG. 20A is a diagram illustrating a magnetic circuit when the ball feeding solenoid 430A according to the second embodiment is attracted, and FIG. 20B is a diagram illustrating a magnetic circuit when the ball feeding solenoid 430A according to the second embodiment is attracted. FIG. 20 (c) is a diagram showing a magnetic circuit at the time of attraction of another ball feed solenoid 490A which is inferior to that of the second embodiment, and FIG. 20 (d) is shown in FIG. 20 (c). It is a figure which shows the magnetic circuit at the time of adsorption | suction of the ball feed solenoid 490A.

  As shown in FIG. 19B, in the non-attraction state of the ball feed solenoid 430A of the second embodiment, the base end side of the movable piece 450 is pulled by the spring 471, and the movable piece 450 is separated from the fixed iron core 441. However, as shown in FIG. 20A, when the ball feed solenoid 430A of Example 2 is attracted, the coil 443 of the ball feed solenoid 430A is energized, and in addition to the magnetic circuit shown by the solid line, Another novel magnetic circuit (additional magnetic circuit) shown is formed. In a ball feed solenoid 490A different from the present embodiment shown in FIG. 20 (c), only a magnetic circuit indicated by a solid line is formed. That is, in the ball feed solenoid 430A of this embodiment, another new magnetic circuit (additional magnetic circuit) indicated by a broken line is formed, so that it is compared with the ball feed solenoid 490A of FIG. The suction power is increasing (up). Further, as shown in FIG. 20A, since the movable piece 450 and the first upright plate portion 444b of the yoke 444 are in contact with each other in the non-attraction state, magnetism easily passes through the contact portion. For this reason, the suction force at the start of suction is increased.

  As shown in FIG. 20 (b), when the coil 443 is energized and the movable piece 450 is in the suction state, the ball feed solenoid 430A of the second embodiment includes both the standing plate portions 444b, There is a non-contact gap between 444c and the metal plate 454 of the movable piece 450 and between the fixed iron core 441 and the metal plate 454 of the movable piece 450. The circuit is formed without any problem, and the suction state of the metal plate 454 of the movable piece 450 to the fixed iron core 441 can be favorably maintained.

  By the way, when the energization to the coil 443 is stopped and the energization is stopped, in the ball feed solenoid 430A of the second embodiment, as described above, both the standing plate portions 444b and 444c and the metal of the movable piece 450 are used. Since gaps are formed in a non-contact manner between the plate 454 and between the fixed iron core 441 and the metal plate 454 of the movable piece 450, these gaps serve as the breaking points SP of the magnetic circuit, and residual magnetism. Therefore, the movable piece 450 can be quickly separated from the fixed iron core 441. That is, in the ball feed solenoid 490A shown in FIG. 20D, the tip side of the yoke 444 and the metal plate 454 of the movable piece 450 are in contact with each other while the metal plate 454 of the movable piece 450 is attracted to the fixed iron core 441. Therefore, even if the coil 443 is not energized, there is a problem that the movable piece 450 is not separated from the fixed iron core 441 due to an attractive force due to residual magnetism, or is difficult to leave. That is, in the ball feed solenoid 430A of the second embodiment, both magnetic circuits can be cut by a gap (two blocking points SP) between both the standing plate portions 444b and 444c and the metal plate 454 of the movable piece 450. Therefore, as compared with the ball feed solenoid 490A of FIG. 20D, the attractive force due to the residual magnetism can be extremely reduced.

  As described above, according to the ball feed solenoid 430A of the second embodiment, the base end side of the movable piece 450 is biased to the first standing plate portion 444b of the yoke 444 via the nonmagnetic member 470. Since the spring 471 is provided, when the coil 443 is not energized, naturally, a magnetic circuit passing through the fixed iron core 441, the yoke 444, and the movable piece 450 is not formed, so that the movable piece 450 is attracted toward the fixed iron core 441. No suction force is generated, and the base end side of the movable piece 450 is only pulled toward the first standing plate portion 444b by the spring 471. Therefore, the base end side of the movable piece 450 is used as a rotation shaft. The leading end side of the movable piece 450 is separated from the leading end side of the second standing plate portion 444c (non-suction state: one-side open state). Even when the movable piece 450 is in a single-open state (non-attraction state), since the distal end side of the first standing plate portion 444b and the proximal end side of the movable piece 450 are in contact with each other, magnetism is passed even at this contact location. Therefore, as much as magnetism can be passed through the contact location, a suction force for attracting the movable piece 450 when the coil 443 is energized can be secured, and can be favorably attracted.

  In addition, as shown in FIG. 19, the ball feed solenoid 430A of the second embodiment is a flapper type solenoid, and the base end of the movable piece 450 is disposed on the first standing plate portion 444b via the non-magnetic member 470. A spring 471 (coil spring) that biases the side is provided, but the non-magnetic member 470 is not provided on the first standing plate portion 444b, but the biasing means (for example, the spring 471 or the leaf spring) itself is provided. A non-magnetic material may be employed. In this case, it is not necessary to provide the nonmagnetic member 470 on the first standing plate portion 444b.

  Next, the pachinko machine 10 according to the third embodiment will be described with reference to FIG. FIG. 21A is a plan view showing a schematic configuration of the ball feed solenoid 430B of the third embodiment at the time of non-suction, and FIG. 21B is a side view of the ball feed solenoid 430B shown in FIG. FIG. 21C is a plan view showing a schematic configuration of the ball feed solenoid 430B of the third embodiment at the time of suction, and FIG. 21D is a side view of the ball feed solenoid 430B shown in FIG. 21 (e) is a diagram showing a magnetic circuit when the ball feed solenoid 430A of the second embodiment is attracted, and FIG. 21 (f) shows a magnetic circuit when the ball feed solenoid 430B of the third embodiment is attracted. FIG.

  The ball feed solenoid 430B according to the third embodiment is provided with an extending portion 480 which is bent and extended toward the second standing plate portion 444c of the yoke 444 on the distal end side of the movable piece 450. The portion 480 is different from the second embodiment described above in that the movable piece 450 is not in contact with the second standing plate portion 444c even in the suction state. In addition, description is abbreviate | omitted about the content similar to the above-mentioned Example 2, and suppose that the ball | bowl feed solenoid 430B in this Example 3 is demonstrated in detail below.

  As shown in FIG. 21, the movable piece 450 of the ball feed solenoid 430 </ b> B according to the third embodiment has an extended portion that is bent and extended toward the second standing plate portion 444 c of the yoke 444 on the tip side. 480, and the extended portion 480 is not in contact with the second standing plate portion 444c even when the movable piece 450 is sucked.

  In the third embodiment, the extension portion 480 is bent in an L shape toward the second standing plate portion 444c of the yoke 444, but is bent toward the second standing plate portion 444c. As long as it has a shape, various shapes such as an arc shape may be employed.

  The movable piece 450 of the third embodiment is provided with two extending portions 480 on the distal end side thereof, but may be one or more.

  Here, the suction operation of the ball feed solenoid 430B according to the third embodiment will be described below.

  As shown in FIG. 21E, in the non-attraction state of the ball feed solenoid 430A of the second embodiment, the base end side of the movable piece 450 is pulled by the spring 471, and the movable piece 450 is separated from the fixed iron core 441. Similarly, even in the non-attraction state of the ball feed solenoid 430B of the third embodiment, similarly, as shown in FIG. 21 (f), the base end side of the movable piece 450 is pulled and the movable piece 450 is separated from the fixed iron core 441. In the case of the ball feed solenoid 430B of the third embodiment, the movable piece 450 and the yoke 444 are moved by the extending portion 480 on the distal end side of the movable piece 450 as compared with the case of the second embodiment. The distance from the second upright plate portion 444c is shorter, and the ball feed solenoid 430B of the third embodiment is more easily magnetized between the distal end side of the movable piece 450 and the second upright plate portion 444c. Have . Therefore, as shown in FIG. 21F, the ball feeding solenoid 430B of the third embodiment has an increased suction force compared to the ball feeding solenoid 430A of the second embodiment.

  When the ball feed solenoid 430B of Example 3 is attracted, as shown in FIG. 21 (f), the coil 443 of the ball feed solenoid 430B is energized, and in addition to the magnetic circuit shown by the solid line, another new one shown by the broken line is shown. Another magnetic circuit (additional magnetic circuit) is formed.

  When the coil 443 is energized and the movable piece 450 is attracted, the state of the state is omitted, but the ball feed solenoid 430B of the third embodiment has both the standing plate portions 444b and 444c. A gap is formed between the fixed iron core 441 and the metal plate 454 of the movable piece 450 in a non-contact manner, but is a minute gap. Is formed without any problem, and the suction state of the metal plate 454 of the movable piece 450 to the fixed iron core 441 can be satisfactorily maintained. In addition, a gap is formed in a non-contact manner between the extending portion 480 and the second standing plate portion 444c, but since it is a minute gap, the magnetic circuit is formed without any problem, and the movable piece 450 The suction state of the metal plate 454 to the fixed iron core 441 can be favorably maintained.

  By the way, when the energization to the coil 443 is stopped and the energization is stopped, in the ball feed solenoid 430B of the third embodiment, as described above, both the standing plate portions 444b and 444c and the metal of the movable piece 450 are used. A gap is formed in a non-contact manner between the plate 454, between the fixed iron core 441 and the metal plate 454 of the movable piece 450, and between the extending portion 480 and the second standing plate portion 444c. For this reason, these gaps serve as the breaking points SP of the magnetic circuit, the attractive force due to the residual magnetism can be extremely reduced, and the movable piece 450 can be quickly separated from the fixed iron core 441.

  As described above, according to the ball feed solenoid 430B of the third embodiment, the movable piece 450 includes the extended portion 480 that is bent and extended toward the second standing plate portion 444c on the distal end side thereof. Since the extending portion 480 is not in contact with the second standing plate portion 444c even when the movable piece 450 is attracted, when the coil 443 is not energized, the distal end side of the movable piece 450 is the second standing plate portion 444c. Although it is in a state separated from the distal end side (non-suction state: one-sided open state), an extension portion bent and extended toward the second standing plate portion 444c is provided on the distal end side of the movable piece 450. Since there is 480, the extension part 480 on the distal end side of the movable piece 450 is located at a position close to the second standing plate part 444c, so that the suction force can be increased by the amount close to that. In the suction state of the movable piece 450, the movable piece 450 is sucked with a predetermined gap from each of the fixed iron core 441 and both the standing plate portions 444b and 444c, and the extension portion Since 480 is not in contact with the second upright plate portion 444c even when the movable piece 450 is attracted, when the coil 443 is de-energized, the magnetic circuit is cut off by the gap therebetween, and the residual magnetism The adsorptive power by can be made extremely low.

However, a member different from the bobbin 442 is used to separate the metal plate 454 of the movable piece 450 and the fixed iron core 441 from each other. You may make it open. That is, it is a member to which the movable piece 450 of the solenoid in the attracted state is brought into contact, and is a portion that protrudes slightly from the outer peripheral region of the fixed iron core 441 on the front end side and from the front end side surface of the fixed iron core 441. The bobbin 442 may be provided with a contacted part that is separate from the bobbin 442. For example, a bobbin 442 around which a coil 443 is wound is placed in a cylindrical part (which may be a square cylindrical part or the like) formed of a nonmagnetic resin, and the height of the cylindrical part is One that is slightly higher than the height of the upright plate portion of the yoke 444 may be used. In such a case, the exterior tape of the coil 443 can be made unnecessary, a failure such as disconnection due to an external force can be reduced, and a simple waterproof mechanism can be obtained.
