Patent number: 6022020Abstract: A game machine in which an endless belt is circularly moved such that an upper face thereof is moved from a background side to a foreground side relative to a player. A target moving in a crosswise direction of the endless belt is provided at an upstream side of the endless belt. A disk shooter provided at a downstream side of the endless belt is operated so as to aim a shooting chute of the disk shooter at the target. A disk is shot from the disk shooter upon pressing a shooting button for activating the disk shooter. The shot disk advances toward the target, rolling on the endless belt. In case the disk hits the target, a score is obtained. The score is added and indicated by a score indicator. The disk having reached the upstream side strikes a stopper plate and falls on the endless belt. The laid disk is conveyed to the downstream side in accordance with the circular movement of the endless belt.Type: GrantFiled: June 26, 1998Date of Patent: February 8, 2000Assignee: Unikiki Co., Ltd.Inventor: Ikuo Nishikawa

Patent number: 4597309Abstract: A device for regulating the direction of rotation of a slot machine handle is disclosed, which ensures reliable forward and return motions of the handle. A rack member is moved through a guide member in an interlocked relation to the handle. A rachet pawl is rotatably mounted in the guide member. The rack member has a series of teeth thereon, with a recess at each end of the series. Only when the pawl is in one of those recesses, can the direction of movement of the rack be reversed. As a result, only when the handle has been fully pulled, or fully returned, can its direction of rotation be reversed.Type: GrantFiled: August 1, 1983Date of Patent: July 1, 1986Assignee: Kabushiki Kaisha UniversalInventor: Ikuo Nishikawa

Patent number: 4524636Abstract: A device for locking a slot machine handle for causing the rotation of reels until a coin is inserted, is disclosed. When a coin is inserted, a solenoid is activated to move an interlock lever from a first position to a second position. When the interlock lever is in the first position, it holds a locking pawl in engagement with a locking member provided on the same shaft as the handle. When the interlock lever is brought to the second position, it is held in this position until the handle is returned to the initial position. With the interlock lever in the second position, the locking pawl is allowed to be disengaged from the locking member by a spring.Type: GrantFiled: July 19, 1983Date of Patent: June 25, 1985Assignee: Kabushiki Kaisha UniversalInventor: Ikuo Nishikawa

Patent number: 4522399Abstract: A device for generating an impact sound for a slot machine is disclosed, which is constructed to intentionally produce an impact sound when reels start to be rotated by motors. An operating member is rotated in an interlocked relation to the rotation of a handle while storing restoring force in a spring. When the handle is turned to a predetermined extent, the motors are started to cause rotation of the reels. Substantially simultaneously with the start of rotation of the reels, the operating member is returned by the restoring force stored in the spring, and an impact force is generated with the collision of the returned operating member with a stopper.Type: GrantFiled: August 29, 1984Date of Patent: June 11, 1985Assignee: Kabushiki Kaisha UniversalInventor: Ikuo Nishikawa
