  The present invention relates to a decorative body lifting / lowering unit and a game board which can exhibit a characteristic effect in the progress of a game by moving the decorative body as a heavy object up and down on the surface of the game board constituting the pachinko gaming machine. , And a pachinko machine.

In pachinko machines, various board parts such as a prize opening, windmill, variable display device, and lighting device are provided on the board surface of the game board in order to diversify the contents of the game, winning prizes during the game, and other situation changes The stage effect is enhanced by moving the movable panel surface parts in various directions.
For example, when a game ball wins a start winning opening provided on the game board, the symbol displayed on the variable display device in the game board starts to change, and the symbol stopped after a predetermined time elapses is a predetermined jackpot symbol. When it becomes, it becomes a big hit state, and a player can acquire a lot of balls. In such a gaming machine, various display effects are performed in order to enhance the interest of the game.

For example, in Patent Document 1, an effect member arranged so as to be movable up and down on the front surface of a game board is designed to move up and down instantaneously with a long stroke in conjunction with the display content of a symbol display device in a certain gaming state. A mechanism is disclosed. This accessory mechanism is composed of a motor, a gear, a rotating plate, an arm, etc., and uses the driving force from the motor when raising the effect member, but uses the driving force from the motor when lowering the effect member. Uses a configuration that blocks and drops by its own weight.
When a moving part, a motor, a gear, a light emitting part, a printed circuit board, and the like are mounted on the effect member, and the effect is diversified, the weight of the effect member is inevitably increased. When the accessory mechanism according to Patent Document 1 is used to raise and lower such a production member as a heavy object, the weight of the production member drops when the production member descends. For this reason, a large load is repeatedly applied to the gear, the rotating plate, the arm and the like constituting the accessory mechanism when the effect member is lowered, and the durability is likely to be lowered.

In addition, in order to move the effect member as a heavy object up and down with a single motor, it is necessary to use a large motor with a large output, and the accessory mechanism becomes large, resulting in layout limitations. In any case, when a single motor is used, there is a problem that a situation in which the motor output cannot cope with the weight of the production member is likely to appear, and the feeling of speed and dynamism in the ascending / descending operation of the production member must be reduced. is there.
In addition, since the production member of Patent Document 1 is lifted and lowered at the center upper position of the game board surface and is concealed on the back side of the blindfold plate when it is raised, even if the accessory mechanism is arranged on the back side of the production member You can devise any number of ways to hide the actor mechanism and hide it from the player.
However, when there is no method for concealing the accessory mechanism, such as when a large variable display device is arranged on the back side of the path on which the effect member moves up and down, adopting the accessory mechanism according to Patent Document 1 is not possible. Have difficulty.
JP 2007-7057 A

Can be increased.
The shaft support portion 41c that supports the other end portion 40b of the link member 40 is set as close to the other end portion 41b of the arm 41 as possible, so that the link member 40 swings as the drive gear 38 rotates. A part of the link member is prevented from projecting into the central opening of the center member 7 and being viewed from the front.

The pin 42 provided at the one end 41 a of the arm 41 is allowed to move in the lateral direction of the decorative body relative to the arm 41 by loosely fitting into a horizontally long slot 32 provided on the back surface of the decorative body 30. Thereby, it is possible to prevent an excessive load from being applied to the connecting portion between the arm 41 and the decorative body when the decorative body is moved up and down, and the decorative body is moved up and down smoothly.
Since the drive gear 38 integrated with the output shaft of the drive motor 37 is in the state shown in FIGS. 3A and 4A, the support shaft 39a of the driven gear 39 that meshes with the drive gear 38 is located above. The link member 40 whose one end is supported by the support shaft 39a is in a state where the arm 41 is pulled up. The arm 41 raises the one end portion 41a around the other end portion 41b pivotally supported by the swing shaft 36a by a force that pulls upward on the shaft support portion 41c.

  At the normal time, the decorative body 30 is stopped at the raised position shown in FIGS. 3 (a) and 4 (a). When a drive start signal in the downward direction is output from the control means to the drive motors 37, the drive motors 37 are energized to drive the gears 38, the driven gears 39, the link members 40, and the arms 41. The driving force in the downward direction is transmitted to the decorative body 30, and the decorative body 30 is lowered. When the decorative body 30 is completely lowered, the energization of the drive motors 37 is interrupted and stopped. When a signal instructing driving in the upward direction is output from the control means, both drive motors 37 are energized to start reverse rotation, and each drive gear 38, each driven gear 39, each link member 40, and each arm 41. The driving force in the upward direction is transmitted to the decorative body 30, and the decorative body 30 is raised. The switches SW provided in both the lifting and lowering units 35 operate when detecting the detected parts provided in the respective arms 41 and output a detection signal to the control means, and the control means energizes the drive motor based on this detection signal. Cut off.

In the present invention, most of the members constituting the elevating unit 35 are concealed behind the left and right side portions 7a and 7b of the center member, but only the arm 41 whose one end is pivotally supported by the decorative body 30 is a decorative body. Can be visually recognized slightly from the space between the left and right side edges and the inner side edges of the left and right side portions 7a and 7b of the center member. In this way, the minimum necessary components are only visible and hidden in the central opening of the center member, so that the player's interest is not reduced.
