Definitions

  • the present invention relates to a reel-type gaming machine having a plurality of reels on each of which a plurality of symbols are formed and motors each of which rotates each reel, the gaming machine detecting rotation reference positions of the reels.
  • a reel drive device for a reel-type gaming machine (for example, Japanese Pachi-slot machine) generally outputs a signal pulse representing a reel rotation reference position as a reset pulse, the reel drive device installed in a stepping motor (for example, the stepping motor is a direct-drive type motor that a rotation shaft thereof can be directly put in a central hole of the reel).
  • the reel drive device installed in a stepping motor (for example, the stepping motor is a direct-drive type motor that a rotation shaft thereof can be directly put in a central hole of the reel).
  • the other type of reel drive device there is a reel drive device which is installed out of the stepping motor and outputs the above rest pulse by detecting a detection member to specify the reel rotation reference position.
  • the reel drive device since the above reel drive device is not installed beforehand in a general stepping motor, a designer of the gaming machine has to design so that the reel drive device can be installed in a peripheral construction of the reel.
  • a reel drive device which is constructed so as to output the reset pulse by detecting a detection member formed in the reel.
  • the reel drive device can detect the detection member by detecting whether sensor light emitted from the reel drive device is transmitted through the detection member or not.
  • the present invention has been done to resolve the above problems and it is an object to provide a reel drive device in which the detection member can be surely detected by arranging the detection member in the gear member formed from opaque material, the gear member being arranged in the reel and rotating the reel by receiving rotation force from the motor.
  • a reel drive device comprising:
  • the gear member is formed from opaque material and the detection member is formed into one body with the gear member.
  • the position detector has a light emitting part and a light receiving part and detects the rotation reference position of the reel based on that sensor light emitted from the light emitting part is interrupted by the detection member when the detection member positions between the light emitting part and the light receiving part.
  • the light emitting part and the light receiving part are integrally formed in the position detector and the detection member is constructed so as to reflect the sensor light emitted from the light emitting part.
  • the position detector detects the rotation reference position of the reel based on that the light receiving part receives the sensor light reflected through the detection member.
  • the reel drive device of the present invention since the detection member is not arranged on the cylindrical member of the reel formed from transparent material but is arranged on the gear member formed from opaque material, the reel drive device can surely detect the detection member through the position detector. That is to say, in the reel drive device, when the reel is positioned at the predetermined position, the sensor light emitted from the light emitting part in the position detector is surely interrupted by the detection member formed from opaque material, thereby the position detector can surely detect the detection member.
  • the detection member can be surely detected by forming the detection member in the gear member formed form opaque material.

  • Fig. 1 in front of a cabinet forming a whole construction of the drum-type gaming machine 1, three panel display windows 5L, 5C, 5R are formed. Reels 3L, 3C, 3R constructing a reel unit are seen and recognized through the panel display windows 5L, 5C, 5R, respectively. And on the panel display windows 5L, 5C, 5R, three pay lines 6 are described along three horizontal directions and two pay lines 6 are described along two oblique directions. These pay lines 6 are made effective according to the number of coins inserted through an insertion slot 7 and the number of pay lines 6 are determined.
  • Each of the reels 3L, 3C, 3R starts to rotate when a player inserts coins in the insertion slot 7 and operates a start lever 9. And when the player presses stop buttons 4L, 4C, 4R arranged corresponding to the reels 3L, 3C, 3R respectively, rotation of the reels 3L, 3C, 3R is stopped. Further, based on symbol combination of each of reels 3L, 3C, 3R which are seen and recognized through each of the panel display windows 5L, 5C, 5R when rotation of the reels 3L, 3C, 3R is stopped, winning mode is determined. And when winning is obtained, coins the number of which corresponds to the winning mode are paid out to a coin tray 8.

  • a speed reduction transmission mechanism 700 is arranged between a drive shaft 70A of the stepping motor 70 and a rotation shaft of the reel 3, as shown in Fig. 3. This speed reduction transmission mechanism 700 transmits rotation of the stepping motor 70 to the rotation shaft of the reel 3 with a predetermined reduction ratio.
  • the speed reduction transmission mechanism 700 has two gears, one of which is an output gear 71 put on the drive shaft 70A of the stepping motor 70 and the other is an input gear 72 meshing with the output gear 71 and being arranged in the reel 3 so that the rotation center of the input gear becomes the same shaft center as the rotation shaft of the reel 3.
  • the input gear 72 as mentioned later, is installed in the cylindrical member 32.
  • the output gear 71 transmits rotation of the stepping motor 70 to the reel 3 by meshing with the input gear 72.
  • the speed reduction transmission mechanism 700 is constructed so as to transmit rotation of the stepping motor 70 to the reel 3 while reducing rotation number of the stepping motor 70 to 1/7 thereof.

  • the spring 75 which is prevented from coming off by the stopper screw 73, presses the input gear 72 toward the support plate 80 through the color 74b by its resilient force. At that time, frictional force occurs between the input gear 72 and the support plate 80, thereby the spring 75 can decline vibration of the reel 3 occurring when the reel 3 is stopped.
  • two cylindrical projection portions 72a and 72b are integrally formed from both sides of the plate portion. Both the cylindrical projection portions 72a, 72b are perpendicularly projected from both sides of the plate portion, thereby the rotation support portion 76a can be inserted through the cylindrical projection portions 72a, 72b along an axis passing through the center of the cylindrical projection portions 72a, 72b.
