The overflow storage box 32 stores the medals 30 discharged from the storage tank 33 when the medals 30 stored in the storage tank 33 of the hopper device 31 exceed a predetermined amount.

  A substantially L-shaped discharge passage 40 is provided in front of the discharge port 34 of the hopper device 31. As shown in FIG. 3, an opening 40a communicating with the discharge port 34 of the hopper device 31 is provided at one end of the payout passage 40, and a medal payout port 22 is provided at the other end.

  The payout passage 40 includes a first inclined surface 41 and a second inclined surface 42, and a step 43 is provided between the first inclined surface 41 and the second inclined surface 42. Further, in the dispensing passage 40, an upper wall 44 that faces the first slope 41 is formed in parallel to the first slope 41. The upper wall 44 is formed with an insertion hole 44a through which the upper end of each of the rotation shaft 50a of the impeller 50 and the rotation shaft 51a of the impeller 51, which will be described later, is inserted.

  As shown in FIGS. 4 and 5, the side walls 45 and 46 connected to the first slope 41 are formed to be parallel to each other. The side wall 45 is formed with an opening 45a through which the blade 50b rotating around the rotation shaft 50a of the impeller 50 can pass. Similarly, an opening 46 a is formed in the side wall 46. Two arc-shaped notches 41a are formed on the first slope 41 so as to be symmetric with respect to the center line 47 (see FIG. 5).

  As shown in FIGS. 2, 4, and 5, impellers 50 and 51 are arranged in parallel in the payout passage 40. The impellers 50 and 51 are arranged symmetrically about a center line 47 that bisects the first slope 41 horizontally.

As shown in FIG. 4, the impeller 50 is comprised from the rotating shaft 50a, the blade | wing 50b, and the flange 50c. The impeller 50 is a molded product formed of resin, and the rotating shaft 50a, the blade 50b, and the flange 50c are integrally formed.
The rotating shaft 50a is formed in a cylindrical shape. Further, the rotary shaft 50a and the flange 50c are formed so that the rotary shaft 50a passes through the center of the disk-shaped flange 50c, and on the side peripheral surface of the rotary shaft 50c protruding upward from the upper surface of the flange 50c. Four plate-like blades 50b are formed at equal intervals along the circumferential direction. The blade 50b is formed from the side peripheral surface of the rotating shaft 50a to the edge of the flange 50c, and the blade 50b and the flange 50c are formed integrally.

  One end of the rotating shaft 50a slightly protrudes above the axial height of the blade 50b, and is inserted into the insertion hole 44a in the upper wall 44 of the dispensing passage 40. The other end is fixed to a bearing 59a (see FIG. 6) of a gear 59 provided on the back side of the first inclined surface 41. The flange 50c is disposed in the notch 41a so that the upper surface of the flange 50c and the first inclined surface 41 are flush with each other.

The axial length of the blade 50b is designed to be slightly smaller than the distance t (see FIG. 3) from the first slope 41 to the upper wall 44. Further, the length h (see FIG. 5) of the blade 50b from the rotation shaft 50a is set such that the blade 50b of the impeller 50 and the impeller in the discharge passage 40 when the width of the discharge passage 40 is w (see FIG. 5). It is designed to be slightly smaller than w / 2 so that the 51 blades 51b can rotate without interference. Further, in order to prevent the medal 30 discharged from the hopper device 31 from being sandwiched between the blade 50b of the impeller 50 and the blade 51b of the impeller 51 that form a fan-like space in a plan view, the length h Is designed so as to satisfy the relational expression h <(√2 / 2) × φ where φ is the diameter of the medal 30 (see FIG. 4).
Since the impeller 51 has the same configuration as the impeller 50, the description thereof is omitted. In addition, the code | symbol 51a, 51b, 51c in a figure shows a rotating shaft, a blade | wing, and a flange in order.

  As shown in FIG. 6, a gear unit 55, a motor 56, a rotary encoder 57, and a rotating piece 58 are provided on the back side of the first slope 41. The gear unit 55 includes gears 59 to 62, and the gear 59 is connected to the gear 60 via gears 61 and 62. The rotating shaft 50 a of the impeller 50 is connected to the bearing 59 a of the gear 59. Similarly, the rotating shaft 51 a of the impeller 51 is connected to the bearing 60 a of the gear 60. A driving shaft (not shown) of the motor 56 is connected to the bearing 62 a of the gear 62, and the driving force of the motor 56 is transmitted to the gear 62 through this driving shaft. Furthermore, it is transmitted to the rotating shaft 50 a of the impeller 50 through the gear 61 and the gear 59, and is transmitted to the rotating shaft 51 a of the impeller 51 through the gear 60. Thereby, the blade | wing 50b of the impeller 50 and the blade | wing 51b of the impeller 51 rotate in synchronization.

  A rotary encoder 57 that is an optical rotation angle sensor is provided adjacent to the gear 61. The rotary encoder 57 is connected to a control circuit 63 having a CPU (not shown) that controls the entire slot machine 2. The control circuit 63 is connected to the speaker 9, the lamp 10, and the error code display device that function as the alarm device 64.

  The rotary encoder 57 is for detecting the rotation angle of the gear 61. A plurality of slits (not shown) are formed in the gear 61 at regular intervals along the circumferential direction. The rotary encoder 57 is provided with a light projecting unit and a light receiving unit (not shown). Light is projected from the light projecting section through the slit, and this light is received by the light receiving section. Since the slits are formed at equal intervals, when the gear 61 is rotated at a constant cycle by receiving the driving force of the motor 56, the light receiving unit receives light at a constant time interval. The received light is output to the control circuit 63 as an electrical signal. Based on this electrical signal, the control circuit 63 calculates the rotation angle of the gear 61 as a detection result of the rotary encoder 57. In the ROM area of the control circuit 63, information on the rotation angle of the gear 61 that is rotated at a constant cycle by the motor 56 is stored in advance including errors.

The control circuit 63 compares the information with the detection result of the rotary encoder 57. When the information is different from the detection result of the rotary encoder 57, that is, when the gear 61 stops or rotates reversely against the driving force of the motor 56, the control circuit 63 notifies the alarm 64 (notification means). ), The lamp 10 is turned on, and a warning sound is generated from the speaker 9. Further, an error code for notifying the abnormality is displayed through the error display window 24 by an error code display device provided in the housing 3. In this case, since the lamp 10 is turned on using a light emission color different from the light emission color of the lamp used in the game effect, the game hall employee can easily find the slot machine 2 in which an abnormality has occurred. Can do.
As described above, the rotation prevention detecting means for detecting whether or not the rotation in the predetermined direction (refer to the direction of the circular arrow in FIGS. 5 and 6) is blocked is configured by the rotary encoder 57 and the control circuit 63. Is done. In addition, the control circuit 63 has a function as notification control means for notifying that the rotation is blocked by the notification device 64.

  Further, when the gear 61 stops or reversely rotates against the driving force of the motor 56, the operation of the hopper device 31 is stopped by the control of the control circuit 63 having a function as a game stop control means, The bet on the medal 30 becomes impossible and the game is stopped.

  In this embodiment, the rotation angle of the gear 61 is measured. However, the rotation angle of any of the gears 59 to 62 may be measured, and the blade 50b and the blade wheel 51 of the blade wheel 50 may be measured. The rotational angle of the blade 51b may be directly measured.

  Further, a pressure sensor may be used instead of the rotary encoder 57. For example, when a foreign object 70 (see FIG. 9) such as a wire is inserted from the medal payout opening 22 and the blade 50b of the impeller 50 or the blade 51b of the impeller 51 is pressed by the foreign object 70, the blades 50b and 51b Since the load is applied to the gear unit 55, the load may be detected by a pressure sensor. Thus, what is necessary is just to determine suitably the sensor which detects that rotation of the blade | wing 50b of the impeller 50 and the blade | wing 51b of the impeller 51 is obstructed.

  A rotating piece 58 is provided on the side of the gear 60. The rotating piece 58 includes a locking claw 58a, an arm portion 58b, and a shaft portion 58c. A locking claw 58 a having an inclined portion 58 d is formed at one end of the rotating piece 58. A shaft portion 58c is formed at the other end, and is pivotally attached to the housing 3 so as to be rotatable. A tension coil spring 65 is provided on the arm portion 58b that connects the locking claw 58a and the shaft portion 58c. One end of the tension coil spring 65 is fixed to the arm portion 58 b, and the other end is attached to the housing 3. The rotating piece 58 is urged by the tension coil spring 65 in the direction of the arrow in the figure, and the locking claw 58a is fitted into the tooth groove 60b. When the gear 60 rotates in the direction of the arc, the inclined portion 58d of the locking claw 58a is brought into sliding contact with the teeth of the gear 60, and the locking claw 58a is lifted by the tooth height of the gear 60 (see the two-dot chain line in the figure). . Then, as the gear 60 rotates, the locking claw 58a is fitted into the tooth gap 60b again. Thus, the reverse rotation preventing means is constituted by the tooth gap 60b and the locking claw 58a.

  As shown in FIG. 3, a reflective photosensor 66 is provided on the upper surface of the upper wall 44 of the payout passage 40. The reflective photosensor 66 is disposed between the discharge port 34 of the hopper device 31 and the impeller 50. The upper wall 44 is formed with an opening 44b through which the light projecting portion and the light receiving portion of the reflective photosensor 66 are exposed. The reflection type photosensor 66 emits a light beam from the light projecting portion through the opening 44b into the payout passage 40, and the reflected light reflected by the medal 30 or the first inclined surface 41 remaining in the payout passage 40 is received by the light receiving portion. Receive light.

  As shown in FIG. 3, the reflective photosensor 66 is connected to the control circuit 63. The control circuit 63 monitors the output level of the light receiving unit at predetermined intervals. When the light beam emitted from the light projecting part is reflected by the medal 30 in the payout passage 40, the output level exceeds a predetermined level set in advance. The time exceeding the predetermined level is counted by a timer circuit (not shown) provided in the control circuit 63. When the counted time exceeds a predetermined time, the control circuit 63 determines that medals remain in the payout passage 40. As described above, the medal detection means for detecting whether or not the medal 30 exists in the payout passage 40 for a predetermined time includes the reflection type photosensor 66 and the control circuit 63.

  In the present embodiment, the reflective photosensor 66 is used. However, the present invention is not limited to this, and a non-contact detector such as an electromagnetic sensor or an ultrasonic sensor can also be used.

The control circuit 63 is connected to the speaker 9, the lamp 10, and the error code display device that function as the alarm 64. When a medal is present in the payout passage 40 for a predetermined time, the control circuit 63 outputs an electric signal to the alarm device 64, turns on the lamp 10, and the medal is present in the payout passage 40 from the speaker 9 for a predetermined time. A warning sound for notifying is generated. Further, the error code display device displays an error code for notifying that a medal is present in the payout passage 40 for a predetermined time through the error display window 24. In this case, for the lighting of the lamp 27, a light emission color different from the light emission color of the lamp used in the game effect is used.
As described above, the control circuit 63 has a function as a notification control unit that notifies the notification device 64 that the medal 30 exists in the payout passage 40 for a predetermined time.

  When the presence of the medal 30 is detected by the reflective photo sensor 66 and the control circuit 63, the operation of the hopper device 31 is stopped by the control of the control circuit 63 having a function as a game stop means. At the same time, betting of medals 30 becomes impossible and the game is stopped.

  In the present embodiment, the medal detection means constituted by the reflective photosensor 66 and the control circuit 63 detects whether or not the medal 30 exists in the payout passage 40 for a predetermined time. It may be detected whether a plurality of sheets are stopped in the payout passage 40. In this case, it is preferably detected when three or more medals 30 are stopped in the payout passage 40.

  Next, the operation of the slot machine 2 configured as described above will be described. The blades 50 b of the impeller 50 and the blades 51 b of the impeller 51 provided in the payout passage 40 are rotated by the driving force of the motor 56. As a result of the game, a prize is won, and when the hopper device 31 is operated and the medal 30 is paid out, the medal 30 moves through the payout passage 40 and eventually reaches the position of the impellers 50 and 51 as shown in FIG. To do. When the blade 50b of the impeller 50 and the blade 51b of the impeller 51 are in the first position where the inside of the payout passage 40 is closed (see FIG. 7), the medal 30 is not discharged to the medal payout port 22. Both the blade 50b of the impeller 50 and the blade 51b of the impeller 51 rotate 90 degrees in the direction of the circular arc in the figure, and as shown in FIG. 8, the blades 50b and 51b guide the medal 30 to the medal payout port 22, When the medal 30 in the payout passage 40 is displaced to the second position where the medal is allowed to pass, the medal 30 in the payout passage 40 is discharged to the medal payout opening 22.

  As shown in FIG. 9, when a foreign object 70 such as a wire is inserted from the medal payout opening 22 into the payout passage 40, the direction (see the direction of the straight arrow in the figure) opposite to the insertion direction of the foreign object 70 (see the wire direction) Since the blade 50b of the impeller 50 and the blade 51b of the impeller 51 are rotating in a direction that prevents the insertion), the rotational force of the blades 50b and 51b makes it difficult to insert the foreign material 70. It is possible to prevent entry into the hopper device 31.

  In addition, when the foreign object 70 is inserted into the payout passage 40 against the rotation of the blade 50b and the blade 51b, if the game result is a prize, the foreign material 70 is the blade 50b and the blade 51b. And the blades 50 b and 51 b are prevented from rotating, so that the medal 30 discharged from the hopper device 31 remains in the payout passage 40. When the medal 30 remains in the payout passage 40 for a predetermined time, the reflection type photo sensor 66 and the control circuit 63 detect the medal 30 remaining in the payout passage 40. Then, the control circuit 58 stops the operation of the slot machine 2, reproduces an alarm sound or the like from the speaker 9, and turns on the lamp 10.

  In addition, when one of the blades 50b and 51b is pressed with the foreign material 70 and the blades of the impellers 50 and 51 are rotated in the reverse direction, the locking claw 58a bites into the tooth groove 60b of the gear 60. The impellers 50 and 51 can be prevented from rotating in the reverse direction.

  Further, when one of the impellers 50 and 51 is pressed to rotate the impellers 50 and 51 in the reverse direction, or a foreign object 70 is inserted as shown in FIG. When the impellers 50 and 51 are prevented from rotating, the rotary encoder 57 and the control circuit 63 detect that the impellers 50 and 51 are prevented from rotating. Then, the control circuit 63 stops the operation of the slot machine 2, for example, reproduces an alarm sound from the speaker 9, and turns on the lamp 10.

  As described above, it is possible to prevent the act of inserting the foreign object 70 from the medal payout opening 22 and illegally operating the hopper device 31 to pay out the medal 30. For example, the number of medals 30 to be discharged is set by continuously turning on a detection sensor (not shown) that counts medals 30 discharged from the hopper device 31 until the number of medals 30 corresponding to a prize is reached. In the case of a fraudulent act of impersonation, the foreign object 70 has to enter from the gap between the blade 50b of the impeller 50 and the blade 51b of the impeller 51. At that time, the introduced foreign object 70 becomes an obstacle and the blade 50b , 51b causes inconvenience, so that fraud can be prevented.

When the control circuit 63 controls the driving of the motor 56 and the hopper device 31 does not pay out the medal 30, the blade 50b of the impeller 50 and the blade of the impeller 51 are shown in FIG. 51b may be stopped at a position where the payout passage 40 is closed, and when the medal 30 is paid out, the motor 56 may be operated to rotate the blades 50b and 51b.
Further, in the case of the hopper device 31 in which the medals 30 are accommodated one by one in a hole of a rotor disk (not shown) and the medals 30 are discharged from the discharge port 34 by rotating the disks, the medals 30 are removed from the disks. It is preferable to rotate the disk and the blades 50b and 51b in synchronism, taking into account the time until they are discharged and reach the impellers 50 and 51. Alternatively, a sensor that detects the medal 30 that has passed through the impellers 50 and 51 may be provided, and the rotation of the disk may be driven in response to this detection. In this way, the timing for rotating the blades 50b and 51b may be set so that the medal 30 discharged from the hopper device 31 can pass through the impellers 50 and 51.

  In the above embodiment, the reverse rotation prevention means is constituted by the tooth groove 60b and the locking claw 58a. However, the reverse rotation prevention means is a means for restricting the rotation shafts 50a and 51a to mechanically rotate only in one direction. Alternatively, it may be a means for controlling to stop the rotation when a rotational load is applied in a direction opposite to a predetermined direction, and can be changed as appropriate.

In the above embodiment, the blade 50b of the impeller 50 and the blade 51b of the impeller 51 are rotated using the driving force of the motor 56. However, without using the motor 56, the hopper device 31 has a predetermined momentum. The blade 50b of the impeller 50 and the blade 51b of the impeller 51 may be rotated by pressing the medal 30 to be paid out. The predetermined momentum is momentum required to rotate the blade 50b of the impeller 50 and the blade 51b of the impeller 51.
Further, also in the case where the blade 50b of the impeller 50 and the blade 51b of the impeller 51 are rotated by pressing the medal 30, it is preferable that the gear unit 55 and the locking claw 58a are provided, as in the above embodiment. Thereby, reverse rotation of the blades 50b and 51b can be prevented.
When the blades of the impellers 50 and 51 are arranged at positions as shown in FIG. 9 after the medal 30 has been paid out, the payout passage 40 is formed by the blades 50b and 51b as shown in FIG. It is preferable that the impellers 50 and 51 are rotated by the motor 56 so that the blades 50b and 51b are displaced. The positions of the blades 50b and 51b at this time may be detected by, for example, the rotary encoder 57 and the control circuit 63 described above, and the control circuit 63 may drive the motor 56 based on the detection result. In this way, it is possible to prevent foreign matter from being inserted when the medal is not paid out. Further, it is possible to detect the positions of the blades 50b and 51b using various sensors other than the rotary encoder 57.

  In the above embodiment, four blades 50b of the impeller 50 and four blades 51b of the impeller 51 are configured, but the number of blades of the impellers 50 and 51 is appropriately changed without limitation. good. In this case, since the value of the length h of the blade 50b varies depending on the number of blades 50b, the value of h corresponding to the number of blades 50b is calculated, and the length h of the blade 50b is determined based on the calculated value. It is preferable.

  In the above embodiment, two impellers are provided. However, the present invention is not limited to this, and the number of impellers may be one. In this case, for example, an impeller is provided on one side wall of the payout passage 40 and the length in the short side direction of the impeller blade is designed to correspond to the width w of the payout passage 40.
