Description

  The present invention relates to a push button switch for gaming machines, and more particularly to a button effect structure of a push button switch.

  Conventionally, pachinko machines have been widely used as gaming machines. This pachinko machine is provided with a push button switch to give the player a sense of expectation for the game, etc. by an effect such as blinking of the button part.

  As one of the effects, a method of projecting a button part of a push button switch is known. For example, Patent Document 1 discloses a push button switch for a gaming machine that uses a solenoid as a method of projecting a button portion of the push button switch. In the push button switch described in Patent Document 1, the push button and the engagement piece are engaged by the elastic force of the spring. When the solenoid is operated, the engagement between the push button and the lower surface of the engagement piece is released, and the push button switch is brought into a protruding state by the elastic force of the spring.

  In addition, as a method for enhancing the effect, Patent Document 2 discloses a method of changing an operation load by changing a set length of a compression spring of a push button switch by a solenoid.

  As another method for enhancing the effect, Patent Document 3 discloses a method of attaching a vibration motor to the back side of a push button switch.

JP 2007-296090 A (published November 15, 2007) Japanese Patent Laying-Open No. 2006-280752 (released on October 19, 2006) JP 2007-75331 A (published March 29, 2007)

  However, in the technique of the above-mentioned Patent Document 3, vibration is not transmitted unless the player touches the button portion, and the visual effect is low. On the other hand, in the technique of the above-mentioned patent document 1, by operating the solenoid, the push button switch is in a protruding state and a visual effect can be obtained. There is a problem that there is no movement and the visual effect is still low.

  Moreover, in the technique of the said patent document 2, it is hard for a player to understand that the operation load changed, and a high production effect cannot be obtained.

  Furthermore, in the technique of Patent Document 3 described above, when a motor that applies large vibrations is installed, there is a problem that normal games cannot be performed because the vibrations are transmitted to the gaming machine, affecting the ball flow.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a push button switch and a gaming machine that have a low effect on the gaming machine and a high effect.

  The push button switch according to the present invention is a push button switch operated by a user, and can be pushed from a reference position to a pushing position, and can be moved from the reference position to a protruding position opposite to the pushing position. A button operating unit and an operating unit that operates in a direction opposite to the push-in direction, and the operating unit is abutted against the button operating unit at the reference position, and the button operating unit is moved to the protruding position. A drive device; and an urging member that applies a force to return the button operation unit to the reference position when the button operation unit is shifted from the reference position. There is a gap between the button operating portion and the button operating portion at the push-in position, and the drive device operates the button when the button operating portion is at the push-down position. Abutted to the department.

  According to the above configuration, the button operation unit moves to the protruding position when the driving device is driven when in the reference position, and returns to the reference position by the biasing member when the driving is completed. For this reason, by operating the driving device intermittently, the button operation unit reciprocates between the reference position and the protruding position. Thereby, even if the user does not touch the button operation unit, it can be visually recognized that the user is reciprocating, and the visual effect can be enhanced.

  Further, when the driving device is not driven, a load by the urging member is applied, and when the driving device is driven, a load by the urging member and the operating unit is applied to the button operation unit. Therefore, it is easy for the player to understand that the operation load of the button operation unit has changed between when the drive device is driven and when it is not driven.

  In addition, since there is a gap between the button operation unit and the operation unit at the push-in position, if the user touches the button operation unit, the user may directly feel the impact of the operation unit hitting the button operation unit. it can. Further, since the button operation unit is urged by the urging member, there is little influence on the gaming machine due to the vibration of the driving device.

  From the above, it is possible to provide a push button switch that has a low effect on the gaming machine and a high effect.

  Furthermore, in the push button switch according to the present invention, the button operation unit includes a button cover, and a movable base that is located downstream of the button cover in the push-in direction and moves integrally with the button cover, The urging member includes a first urging member and a second urging member, and the push button switch is disposed between the button cover and the movable base and is movable in the push-in direction. A button guide, and a limiting member that contacts the button guide when the button guide is located at the upper limit position and restricts movement of the button guide in a direction opposite to the pushing direction; The first urging member urges the button guide in a direction opposite to the pushing direction, and the second urging member is movable with the button guide. Is disposed between the over scan, may also be biased away from each other with respect to said button guide and said movable base.

  According to the above configuration, when there is no pushing operation, the button guide is urged by the first urging member in a direction opposite to the pushing direction. Therefore, the button guide and the limiting member come into contact with each other and are locked by the limiting member. As a result, the position of the button guide when there is no pushing operation is determined.

  The movable base is applied with a force (that is, a force in the pushing direction) so as to be separated from the button guide by the second urging member. However, since the button guide is located between the movable base and the button cover integrated with the movable base, the button cover comes into contact with the button guide. As a result, the position of the button operation unit is determined.

  As described above, the reference position of the push button switch when there is no pushing operation can be determined.

  Furthermore, in the push button switch according to the present invention, the limiting member is connected to the fixed portion disposed downstream of the movable base in the push-in direction and the fixed portion, and the button cover side of the button guide And a locking portion that restricts movement of the button guide in a direction opposite to the pushing direction, and the first biasing member is provided between the button guide and the fixing portion. May be arranged.

  According to said structure, even if a button operation part exists in a protrusion position, a button guide does not move from a reference position. Therefore, when the player performs a push-in operation when driving the drive device, the operation load can be changed in each push-in operation from the projecting position to the reference position and from the reference position to the push-in position. Specifically, in the pushing operation from the protruding position to the reference position, the button guide does not move from the reference position, and therefore the force in the pushing direction from the second urging member is pushed to the button operation unit from the driving device. A force in the direction opposite to the direction is applied. On the other hand, in the pushing operation from the reference position to the pushing position, a force in a direction opposite to the pushing direction is applied by the driving device and the first urging member. A high production effect can be obtained by changing the operation load as described above.

  Furthermore, in the push button switch according to the present invention, the first urging member and the second urging member may be coil springs. Thereby, it is possible to reduce the influence on the gaming machine caused by the impact of the operating portion hitting the movable base.

  Furthermore, in the push button switch according to the present invention, the driving device may be a solenoid. Thereby, an action | operation part can be moved up and down by on / off switching of the electric current applied to a solenoid. Moreover, an operation part can also be operated continuously by applying a pulse current to a solenoid. Therefore, a high production effect can be obtained.

  Furthermore, the push button switch of the present invention may be provided in a gaming machine. As a result, it is possible to provide a gaming machine that has a low effect on the gaming machine and a high performance effect.

  According to the present invention, it is possible to provide a push button switch and a gaming machine that have a low influence on the gaming machine and a high effect.

At the time of pressing the button, the reflector 31 moves together with the button guide 25.

  The button cover 32 has a hollow, substantially hemispherical shape. The outer diameter of the lower end of the button cover 32 is smaller than the inner diameter of the wall portion 22 b of the fixed base 22, and the inner diameter of the lower end of the button cover 32 is larger than the outer diameter of the disk portion 25 a of the button guide 25. The button cover 32 is provided with an engagement hole 32 a for engaging with the engagement claw 30 a of the movable base 30 in the lower circumferential direction. When the engaging claw 30a and the engaging hole 32a are engaged, the button cover 32 and the movable base 30 operate integrally. Further, on the inner surface of the button cover 32, a step portion 32 b that abuts on the upper surface of the button guide 25 (the surface on the button cover 32 side) is formed. In the present embodiment, the button cover 32 and the movable base 30 are separated from each other. However, the button cover 32 and the movable base 30 may be molded as a single unit to form a button operation unit.

  The return spring 33 is a coil spring and is disposed between the movable base 30 and the button guide 25 in a state of being contracted from the natural length. Since the return spring 33 applies a downward force to the movable base 30, a downward force is also applied to the button cover 32 that moves together with the movable base 30. However, as described above, the button cover 32 is formed with the stepped portion 32b that comes into contact with the upper surface of the button guide 25 (the surface on the button cover 32 side), so that the button cover 32 and the movable base 30 are affected downwardly. Is limited. Further, the return spring 33 plays a role of biasing the movable base 30 downward when the movable base 30 moves upward (opposite to the pushing direction) by driving a solenoid unit 40 described later. .

  The solenoid unit 40 has a substantially cylindrical shape, and is coaxially disposed on the inner side in the radial direction of the fixed base 22, the substrate 26, and the light guide lens 29. The solenoid part 40 includes a solenoid movable part (actuating part) 42 and a solenoid fixing part 41. The solenoid fixing portion 41 has a hollow bottomed cylindrical shape and has a solenoid coil. Further, the solenoid fixing portion 41 is fixed to the button base portion 21. The solenoid movable portion 42 has an outer shape that covers the solenoid fixing portion 41, and at least a part thereof is disposed in a hollow cylindrical portion of the solenoid fixing portion 41. The solenoid unit 40 is disposed so that a gap remains between the movable base 30 that has been pushed in and the solenoid movable unit 42 when not driven. A current is applied to the solenoid unit 40 by a signal from the substrate 26, and the solenoid movable unit 42 is operated upward (in a direction opposite to the pushing direction). By switching ON / OFF of the current applied to the solenoid unit 40, the solenoid movable unit 42 moves up and down in the axis X direction. Moreover, the solenoid movable part 42 has the impact-absorbing sheet 43 for absorbing an impact on the upper surface.

  As described above, the button cover 32 and the movable base 30 move together. When the player does not push the button cover 32, the position where the locking portion 25d is in contact with the protrusion 22d of the fixed base is the reference position of the button guide 25 as shown in FIG. In the button cover 32 and the movable base 30, the position where the stepped portion 32b is in contact with the button guide 25 at the reference position is the reference position.

(3. Operation of push button switch 16 during push-in operation)
FIG. 6 is a cross-sectional view of the push button switch 16 in the direction of pushing the button when the solenoid unit 40 is not driven and when the push operation is performed (push position).

  9 is an operation diagram in the push button switch 16 of the present embodiment, in which time is taken on the horizontal axis and displacement in the axis X direction from the reference position of the movable base 30 and the button cover 32 is taken on the vertical axis. (A) is an operation | movement figure of the pushbutton switch 16 at the time of pushing-in operation.

  The push button switch 16 operates as a switch when the player pushes the button cover 32.

  When the button cover 32 is pushed in, the button guide 25 in contact with the stepped portion 32b of the button cover 32 is pushed in. Therefore, the sensor light-shielding part 25b provided in the button guide 25 enters the object detection position of the sensor 27, and the switch is turned on.

  As described above, a gap is formed between the movable base 30 at the push-in position and the solenoid movable portion 42.

  At the end of the push-in operation, the button cover 32 and the movable base 30 are returned to the reference position by using the urging force of the button spring 23 that has been compressed by the button guide 25 being pushed in.

(4. Operation of push button switch 16 during solenoid operation when there is no push-in operation)
FIG. 7 and FIG. 9B are a button push-in direction sectional view and an operation explanatory view of the push button switch 16 at the time of solenoid operation (protrusion position) when there is no push-in operation.

  At the time of solenoid operation, the solenoid movable part 42 moves upward by applying a current to the solenoid part 40. Therefore, the gap provided between the solenoid movable part 42 and the movable base 30 disappears, and the solenoid movable part 42 hits the lower end of the movable base 30 and applies an impact to the movable base 30. Thereafter, as the solenoid movable portion 42 moves upward, the movable base 30 moves upward, and the button cover 32 rises together with the movable base 30. Thereby, the player can visually recognize that the push button switch 16 is moving upward.

  As the movable base 30 is raised, the return spring 33 is compressed, and the button guide 25 is applied with an upward force stronger than the reference position. However, the button guide 25 does not move because it is locked to the fixed base 22 by the locking portion 25d. Therefore, a gap between the upper surface of the reflector 31 and the inner surface of the button cover 32 is widened.

  When the application of current to the solenoid unit 40 is stopped, the solenoid movable unit 42 is lowered, and the movable base 30 is pushed down by the compressed return spring 33 and returns to the reference position. Therefore, the button cover 32 that moves integrally with the movable base 30 also moves downward. Therefore, as shown in FIG. 9 (c), by applying a pulse current to the solenoid unit 40, the solenoid movable unit 42 is continuously moved up and down, whereby the movable base 30 and the button cover 32 are moved up and down. It can move continuously. As a result, even if the player does not touch the button cover 32, the player can visually recognize that the push button switch 16 is operating, and the player's expectation can be enhanced. Further, when the wavelength of the applied pulse current is shortened, the movable base 30 and the button cover 32 continuously move up and down at high speed. As a result, the player's expectation can be further enhanced, and if the player touches the button cover 32, the impact of the solenoid movable portion 42 striking the movable base 30 can be felt.

(5. Operation of the push button switch 16 when the solenoid is operated during the push-in operation)
FIG. 8 is a cross-sectional view of the push button switch 16 in the button push direction when the solenoid unit 40 is driven during the push operation.

  When a current is applied to the solenoid unit 40 during the pushing operation, the solenoid movable unit 42 hits the movable base 30 and an impact is transmitted to the player through the button cover 32 integrated with the movable base 30. In the present embodiment, unlike Patent Document 3, since the movable base 30 is not fixed, even if a stronger impact is applied from the solenoid movable portion 42 to the movable base 30, the main body and the game ball of the pachinko machine 1 are applied. The influence of can be reduced. Therefore, the solenoid unit 40 can use a device with a larger output, and even during the push-in operation, the impact of the solenoid movable unit 42 hitting the movable base 30 is sufficiently transmitted to the player, and the player's expectation Can be increased.

(6. Operation of the push button switch 16 when the pushing operation is performed during operation of the solenoid unit 40)
As shown in FIG. 9D, when the player performs a pushing operation when the solenoid unit 40 is driven and the button cover 32 is raised, the button cover 32 together with the solenoid movable unit 42 that contacts the movable base 30. It is necessary to press. Therefore, when the solenoid unit 40 is not driven, it is necessary to perform the pushing operation with a stronger pressure than when the pushing operation is performed on the button cover 32 at the reference position. This gives the player a feeling of operation different from pushing from the reference position, and can increase the player's expectation. In the present embodiment, as described above, the solenoid unit 40 having a large output can be used. Therefore, unlike Patent Document 1, the change in the operation load becomes clear for the player.

  In addition, the current applied to the solenoid unit 40 is controlled by the control unit 17 provided in the pachinko machine 1, and is synchronized with the light emission state of the LED 28 provided on the substrate 26, the display device of the pachinko machine 1, and the like. Thus, the operation state of the button may be appealed to the player. Moreover, the solenoid movable part 42 may not have the impact absorbing sheet 43 and may have a structure in which the solenoid movable part 42 and the movable base 30 directly abut against each other. In that case, the impact sound between the solenoid movable portion 42 and the movable base 30 is not absorbed. Therefore, the structure may be such that the impact sound can be heard by the player.

  The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope shown in the claims, and embodiments obtained by appropriately combining technical means disclosed in different embodiments. Is also included in the technical scope of the present invention.
