  That is, the slide mechanism is configured to continuously change the stroke amount of the slide table 10 by rotating the cams 14A and 14B.

3. Configuration of Cam Switching Mechanism In the present embodiment, the cam to be brought into contact with the rolling roller 182 is selectively switched from the two cams 14A and 14B, so that the type or size of the prize or the payout rate of the prize is selected. Accordingly, the stroke length of the slide table 10 can be changed.

Referring to FIGS. 5A and 5B, the cam switching mechanism includes the following elements.
(1) An insertion hole 185A that is opened on both end surfaces of a support angle 185 provided inside the slide table 10 and supports the rod 181 so as to be rotatable about an axis.
(2) Lever 20 extending from the front end of the rod 181 in a direction perpendicular to the extending direction of the rod 181 (3) Lever knob B that opens through the upper and lower surfaces of the fixed table 6

  The lever 20 is formed integrally with the front end portion of the rod body 181. The length of the lever 20 is determined when the lever 20 is picked from below and the lever 20 is turned 180 degrees clockwise or counterclockwise so as to pass through the opening space of the lever knob B. It is set so as to be received by the peripheral edge of the mouth B.

  In addition, as shown in FIG. 3, the connection point between the rod 181 and the support 184 is set at a position phased in the vertical direction from the center of the rolling surface of the rolling roller 182, and the top and bottom 2 The total thickness of the cams 14 </ b> A and 14 </ b> B is set to be within the height dimension of the slide table 10.

  Therefore, in the above switching mechanism, in order to select the upper cam 14A and shorten the stroke length of the slide table 10, the rolling roller 182 is in contact with the peripheral surface of the lower cam 14B (the chain line in FIG. 3). When the lever 20 is rotated in the clockwise direction, the rolling roller 182 comes into contact with the selected peripheral surface of the upper cam 14A (shown by a solid line in FIG. 3). On the other hand, in order to select the lower cam 14B and increase the stroke length of the slide table 10, the lever 20 is moved from the state where the rolling roller 182 is in contact with the peripheral surface of the upper cam 14A (shown by a solid line in FIG. 3). When rotating counterclockwise, the rolling roller 182 comes into contact with the selected peripheral surface of the lower cam 14B (indicated by a one-dot chain line in FIG. 3).

  In the following description, the upper cam 14A and the lower cam 14B are collectively referred to as “cam 14”.

4). Electrical Configuration Referring to FIG. 6, reference numeral C is a control means that controls the control center, and the following elements are connected to the control means C.
(1) Operation means 4
(2) Premium transfer means 11
(3) Motor 16
(4) Power supply 21 composed of an outlet and a transformer
(5) Coin selector 22 provided in the vicinity of the operating means 4 for each play area 3B
(6) Lottery means 23 that is activated on condition that a predetermined amount of coins is inserted into the coin selector 22
(7) Jackpot effect means 24 which includes the sphere 12 and is activated when the lottery result by the lottery means 23 is jackpot winning.
(8) Storage means 25 which stores the effect program of the jackpot effect means 24, the random number used at the time of the lottery by the lottery means 23, and various control programs.
(9) A payout detection sensor 26 that detects that a free gift has dropped into the free gift outlet 13 and that the dropped free gift has been paid out from the free gift outlet 5

5). Referring to FIG. 7, when the game machine side power source 21 is connected to the fixed power source of the game center and the switch is turned on, the control means C performs predetermined processing based on the detection signal from the coin selector 22. It waits for the amount of coins to be inserted (step S1).

  When a predetermined amount of coins is inserted, the control means C causes the lottery means 23 to execute jackpot lottery while referring to the random numbers stored in the storage means 25 (step S2). The lottery process of this jackpot lottery is displayed on a 7-segment display (not shown) provided in the vicinity of the operation means 4. This indicator is one of the jackpot effecting means 24.

  Next, the control means C determines whether or not the jackpot lottery result is a win (step S3). Here, when the jackpot is won, the control means C operates the jackpot effect means 24 to perform the jackpot effect (step S4). Specifically, the sphere 12 starts to move along the circumferential direction in the prize storage space 8, stops at the selected play area 3B, opens the sphere 12, and allows the prize in the sphere 12 to be transferred to the play area 3B. It is discharged to the prize drop opening 13. If the ball 12 is moved at the same time as the lottery is started in step S2 and the ball is moved in the play area 3B of the game player, the game player is expected to win more visually and dynamically. A feeling can be heightened. When the jackpot effect process ends, the control means C moves the process to step S5. On the other hand, if it is not a win, the control means C moves the process to step S5 without performing the jackpot effect process.

  In step S5, the control means C starts the excavator game. Here, in the excavator game, the transfer means 11 is operated as the game player operates the operation means 4, and the transfer means 11 scoops up the prize placed on the turntable 9 and slides the slide table. 10 and / or the fixed table 6, and the prize drop 13 is generated by the collision between the transferred prize and the prize already on the slide table 10 and / or the fixed table 6, and the reciprocating motion of the slide table 10. This is a game in which a prize is dropped and a prize is acquired from the prize payout port 5.

  Part or all of the prizes transferred from the turntable 9 onto the slide table 10 are dropped onto the fixed table 6 so as to be relatively pushed out by the outer peripheral surface of the turntable 9 by the slide movement of the slide table 10. The Further, the prize dropped on the fixed table 6 by the slide movement of the slide table 10 and the prize originally on the fixed table 6 are directly or indirectly on the front end surface of the slide table 10 in the direction of the prize drop opening 13. The target (through the prize) comes to be pressed. The prizes that have fallen from both side edges of the fixed table 6 are collected by the game machine.

  When the excavator game is started, the control means C determines whether or not a prize has been paid out from the prize payout port 5 based on a detection signal from the payout detection sensor 26 (step S6). Here, when the prize is paid out from the prize payout port 5, the control means C executes the payout appearance according to the program stored in the storage means 25 (step S7). Specifically, a notification means (not shown) is operated to notify the game player that the prize has been successfully paid out. When the payout appearance ends, the control means C ends the game. On the other hand, if the prize is not paid out from the prize payout port 5, the control means C ends the game without performing the above-mentioned payout appearance.

6). When the motor 16 is driven, the rotational force of the output shaft 16A of the motor 16 is transmitted to the rotary shaft 15 via the small pulley 171, the pulley belt 173, and the large pulley 172. Then, both the turntable 9 and the cam 14 rotate at the same time. Due to the rotation of the cam 14, the slide table 10 continuously reciprocates on the fixed table 6. At this time, the rolling roller 182 of the transmission member 18 rolls along the peripheral surface of the cam 14.

  As shown in FIG. 8A, when the peak portion of the cam 14 comes into contact with the rolling roller 182, the transmission member 18 resists the biasing force of the spring 19 and the rotation center (rotating shaft 15) of the cam 14. It is pressed in the direction away from. Therefore, the slide table 10 is pushed out toward the direction close to the prize drop opening 13 (front side as viewed from the game player).

  On the other hand, as shown in FIG. 8B, when the trough of the cam 14 comes into contact with the rolling roller 182, the transmission member 18 is released from the pressing force of the cam 14, and the biasing force of the spring 19 causes the cam 14 to move. It is moved in the direction close to the center of rotation (rotating shaft 15). Therefore, the slide table 10 is drawn toward the direction away from the prize drop opening 13 (back side as viewed from the game player).

7). 3. Cam switching operation As shown by a one-dot chain line in FIG. 3, from the state where the rolling roller 182 is in contact with the peripheral surface of the lower cam 14B, the lever is picked from below the slide table 10, and the lever 20 is picked. When the rod 181 is rotated 180 degrees clockwise around the axis by rotating it 180 degrees clockwise (see FIG. 5) so as to pass through the opening space of the mouth B, the rolling roller 182 As shown by a solid line in FIG. 3, it contacts the peripheral surface of the upper cam 14A. When the motor 16 is driven in this state, the stroke length of the slide table 10 becomes long.

  On the other hand, as shown by a solid line in FIG. 3, from the state where the rolling roller 182 is in contact with the peripheral surface of the upper cam 14A, the lever is picked from below the slide table 10, and the lever 20 is opened to the lever picking opening B. When the rod 181 is rotated 180 degrees clockwise around the axis by rotating 180 degrees counterclockwise (see FIG. 6) so as to pass through the space, the rolling roller 182 in FIG. As indicated by a one-dot chain line, the contact is made with the peripheral surface of the lower cam 14B. When the motor 16 is driven in this state, the stroke length of the slide table 10 is shortened.

8). Action / Effect According to the present embodiment, the following action / effect is achieved.

(1) All the slide tables 10 are reciprocated by one motor 16. Therefore, it can prevent that game machine itself enlarges and control of a game machine becomes complicated. As a result, it contributes to lower manufacturing costs.

(2) The motor 16 is shared between the slide table 10 and the turntable 9, and all the slide tables 10 are reciprocated and rotated by the single motor 16 that is shared. ing. For this reason, the prize game machine 1 includes the turntable 9 in order to give the game player an impactful game characteristic, but the effect (1) is ensured.

(3) The cam to be brought into contact with the rolling roller 182 of the transmission member 18 is selectively switched from the plurality of cams 14. Therefore, the stroke length of the slide table 10, the stroke position of the slide table 10 relative to the fixed table 6, and the stroke cycle of the slide table 10 are varied depending on the size and type (material, shape, etc.) of the prize or the payout rate of the prize. And it can be changed appropriately. As a result, the game center can make appropriate adjustments according to the size, type (material, shape, etc.), payout rate, etc. of the prize.

(4) In particular, the stroke adjusting operation of the slide table 10 is achieved by selectively switching the upper and lower two cams 14A and 14B only by the turning operation of the lever 20. Therefore, the stroke adjustment (setting) work on the game center side is speeded up and simplified.

(5) A rolling roller 182 that rolls along the peripheral surface of the cam 14 is provided at the rear end of the transmission member 18. Therefore, the friction between the peripheral surface of the cam 14 and the rear end portion of the transmission member 18 generated when the cam 14 rotates can be reduced. As a result, the reciprocating motion of the slide table 10 is performed smoothly.

  In addition, this invention is not limited to the said embodiment, Of course, various design changes and corrections within the scope of the claims of this invention can be added.

  As is apparent from the above description, according to the present invention, it is possible to prevent the game machine itself from becoming large and complicating the control of the game machine, thereby reducing the manufacturing cost.
