Description

  The present invention relates to a pachinko gaming machine, and more particularly to a movable accessory device that generates an assist force when a movable accessory is moved from a first position to a second position above by a spring member.

  Conventionally, most of the pachinko gaming machines are equipped with a movable accessory device for game effects, but the movable accessory is moved upward from the first position and the first position by an accessory driving mechanism having an electric motor. The movable accessory device that is driven over the second position is widely put into practical use (for example, see Patent Documents 1 to 3). In the movable accessory devices of Patent Documents 1 and 2, the movable accessory is rotatably supported by the base member, and the accessory driving mechanism includes a gear mechanism including a driven gear fixed to the movable accessory. The driving force is transmitted from the electric motor to the movable accessory by the mechanism.

  In the movable accessory device of Patent Document 3, four sets of movable bodies each having four shutter pieces are interlocked and connected to the ring member. When the ring member is driven to rotate, the four movable body sets are interlocked, and each of the four shutter pieces is retracted from the front side of the screen, and the unfolded position that appears and expands on the front side of the screen. Operates and realizes the shutter action for the screen.

  When the first movable body is driven in one direction by the electric motor, the second movable body receives the driving force from the first movable body by the cam mechanism and resists the biasing force of the spring member from the first position. When driven to the second position and the first movable body is driven in the other direction by the electric motor, the second movable body is driven from the second position to the first position by the biasing force of the spring member and returned. Technology to do is widely adopted. This technique is also disclosed in Patent Documents 1 and 2 separately from the accessory driving mechanism.

The second movable combination 41, 42 is configured to be smaller than the maximum rotational biasing force when the second movable combination 41, 42 is at a position other than the first and second lower positions, and the first, second movable combination 41, 42 is the first. , The rotational biasing force at the second lower position is set to zero. That is, the center of the rotation shaft 52a of the driven gear member 52 is located on the straight line L2.

  Further, the urging means 56 provides the rotational urging force when the first and second movable actors 41 and 42 are in the first and second upper positions, and the first and second movable actors 41 and 42 are the first and second movable actors 41 and 42. It is configured to be smaller than the maximum rotation biasing force at a position other than the second upper position, and with rotation when the first and second movable accessories 41 and 42 are at the first and second upper positions. Set power to 0. That is, the center of the rotation shaft 52a of the driven gear member 52 is located on the straight line L2.

Here, as shown in FIGS. 12 and 13, the spring constant of the spring member 55 is k, and the extension amount of the spring member 55 when the first and second movable accessories 41 and 42 are in the first and second upper positions. X0, the extension amount of the spring member 55 according to the displacement of the first and second movable accessories 41, 42 from the first and second upper positions, x, the second left connecting shaft from the axis of the rotating shaft 52a When the length to the axis of 54b is R, the rotation angle of the driven gear member 52 is θ, and the rotation angle θ when the first and second movable accessories 41 are in the first and second upper positions is 0, The urging force F of the spring member 55 is expressed by the following equation.
F = k (x + x0) = kx + F0
= KR (1-cosθ) + F0 (1)

The lever length L from the axis of the rotating shaft 52a to the straight line L2 is expressed by the following equation.
L = R sinθ (2)
Therefore, from the equations (1) and (2), the rotation urging force M (the rotation moment M) applied to the driven gear member 52 by the urging means 56 is expressed by the following equation.
M = LF = R sinθ [kR (1-cosθ) + F0] (3)

From equation (3), when θ is 0 ° and 180 °, that is, when the first and second movable accessories 41 and 42 are in the first and second upper positions and the first and second lower positions, It can be seen that the dynamic urging force M becomes 0 which is the minimum. Next, assuming that F0 = 0, that is, the extension amount x0 of the spring member 55 at the first and second upper positions of the first and second movable accessories 41 and 42 is 0, the rotation is attached. In order to obtain θ when the force M becomes maximum, the following equation is set from Equation (3).
G (θ) = sinθ (1−cosθ) (4)

Then, from Equation (4), the angle at which the rotational biasing force M is maximized is included in the solution of θ where G ′ (θ) = 0.
That is, G ′ (θ) = cos θ (1−cos θ) + sin θ sin θ
= 1-2cos2θ + cosθ = 0
Solving this, θ = 120 ° when the rotational biasing force M becomes maximum is obtained.
However, actually, since F0> 0, the rotation biasing force M can be set to the maximum when 90 ° <θ <120 °.

  In the lower movable accessory unit 17A, the first and second movable accessories 41 and 42 are rotated from the first and second lower positions to the first and second upper positions (operating positions) by the accessory driving mechanism 43. At the same time, in the upper movable accessory unit 17B, the third and fourth movable accessories 61 and 62 are moved from the third and fourth upper positions to the third and fourth lower positions by the accessory driving mechanism 63. The four movable accessories 41, 42, 61, 62 are rotated to the position (operating position), appear from the center accessory main body 15 a, and form a vortex-like pattern on the screen front side of the image display 16. (See FIG. 2).

  Here, when the first to fourth movable hands 41, 42, 61, 62 are rotated from the retracted position to the operating position, or in a state where they are stopped at the operating position, the first to fourth movable hands are used. The objects 41, 42, 61, 62 are lit up, a specific effect is displayed on the screen of the image display 16, and a specific sound effect is emitted from the speaker 34. , 62 is large in size, it is possible to produce an overall impact.

  Thereafter, contrary to the above, in the lower movable accessory unit 17A, the accessory driving mechanism 43 causes the first and second movable accessories 41 and 42 to be moved downward from the first and second upper positions to the first and first lower portions. At the same time, the third and fourth movable actors 61 and 62 are moved upward from the third and fourth lower positions by the accessory driving mechanism 63 in the upper movable accessory unit 17B. Are rotated to the third and fourth upper positions to return to normal.

  It should be noted that the movements of the first and second movable accessories 41 and 42 from the first and second lower positions to the first and second upper positions and the third and fourth movable combinations 61 and 62 are third and third. The operation from the upper 4 position to the third and fourth lower positions may be executed so as to cause a time difference. In addition, the first and second movable accessories 41 and 42 are moved from the first and second upper positions to the first and second lower positions, and the third and fourth movable combinations 61 and 62 are third and third. The operations from the lower 4 position to the third and fourth upper positions may be executed so as to cause a time difference. Alternatively, only one of the first and second movable combinations 41 and 42 and the third and fourth movable combinations 61 and 62 may be operated.

  The movable accessory device 17 has the following effects. However, here, the effect of the lower movable accessory unit 17A is described, and the effect of the upper movable accessory unit 17B is basically the same as the effect of the lower movable accessory unit 17A, and thus the description thereof is omitted. .

  An electric motor that drives the first and second movable accessories 41 and 42 over the first and second lower positions and the first and second upper positions rotated upward from the first and second lower positions. 50 is driven by the electric motor 50 to transmit the driving force to the first and second movable members 41 and 42, and the driven gear member 52 is rotated. The biasing means having a spring member 55 that generates an assist force when the first and second movable accessories 41 and 42 are rotated from the first and second lower positions to the first and second upper positions. 56.

  Then, the urging means 56 changes the rotation urging force applied to the driven gear member 52 according to the rotation position of the driven gear member 52, so that the first and second movable accessories 41, 42 are changed to the first and second movable accessories 41, 42. The rotational biasing force at the second lower position is configured to be smaller than the maximum rotational biasing force when the first and second movable accessories 41 and 42 are at positions other than the first and second lower positions. Therefore, even if the assist force is changed appropriately and the first and second movable accessories 41 and 42 are large (heavy), the first and second movable combinations 41 and 42 are moved to the first. The first and second movable accessories that can be smoothly and quickly rotated from the second lower position to the first and second upper positions and are stopped at the first and second lower positions by the rotation biasing force. It is possible to prevent a malfunction that 41 and 42 jump up.

  In particular, the urging means 56 makes the rotation urging force 0 when the first and second movable accessories 41 and 42 are in the first and second lower positions, so that they are stopped at the first and second lower positions. Moreover, the malfunction which the 1st, 2nd movable accessory 41 and 42 jumps up can be prevented reliably.

  Here, the rotational speeds of the first and second movable accessories 41 and 42 relative to the rotational speed of the driven gear member 52 (moving speeds of the first and second interlocking connecting members 53 and 54) are the first and second movable parts. Since the combination items 41 and 42 gradually increase as they rotate upward from the first and second lower positions, the rotation urging force also increases gradually in the same manner, and the first and second movable combinations 41 are also increased. , 42 even when the rotational biasing force when the first and second lower positions are 0, the first and second movable accessories 41 and 42 are smoothly started to rotate from the first and second lower positions. 1, it can be rotated to the second upper position.

  Further, the urging means 56 indicates the rotational urging force when the first and second movable combinations 41 and 42 are in the first and second upper positions, and the first and second movable combinations 41 and 42 are other than the second position. Therefore, the first and second movable accessories 41 and 42 are placed in the first and second upper positions against the rotation urging force. Since the load of the accessory driving mechanism 43 that starts to move downward from the position can be reduced, the first and second movable accessories 41 and 42 can smoothly start to move downward from the first and second upper positions. it can.

  In particular, the urging means 56 sets the rotation urging force when the first and second movable combinations 41 and 42 are in the first and second upper positions to 0, so the first and second movable combinations 41 and 42 42 can be smoothly and surely started to move downward from the first and second upper positions.

  Here, when the first and second movable accessories 41 and 42 are in the first and second upper positions, the rotational biasing force is 0, so the first and second stops at the first and second upper positions. There is also a possibility that a malfunction may occur in which the movable accessories 41 and 42 move downward due to their own weight. However, when the first and second movable accessories 41 and 42 are in the first and second upper positions, the axis of the rotating shaft 52a of the driven gear member 52 and the second right connecting shaft 54a of the second interlocking connecting member 54 are provided. Since the shaft center of the second left connecting shaft 54b is in a straight line, the first and second movable accessories 41, 42 are locked via the second interlocking connecting member 54, and the first weight is caused by its own weight. It is possible to reliably prevent malfunctions that move downward from the first and second upper positions.

  Various changes can be made without departing from the spirit of the present invention. For example, in the accessory driving mechanism, various electric actuators such as a solenoid actuator can be employed instead of the electric motor, and various rotation transmission members can be employed instead of the driven gear member. Moreover, in the said Example, although this invention is applied to what rotates two movable actors interlockingly, this invention is applicable to what rotates only one movable actor. Furthermore, the present invention can also be applied to those in which the movable accessory is moved linearly.
