Patent number: 6981913Abstract: A cylindrical body is rotated about a rotation axis interconnecting a center point of a top circle thereof and a center point of a bottom circle thereof. The cylindrical body having an outer peripheral face formed with at least one token-groove. An outer wall member covers the outer peripheral face of the cylindrical body to form a gap between an inner face of the outer wall member and the token-groove such that a single gaming token in an upright attitude is held therein. The gaming token held in the gap is ejected toward a tangent direction of an outer peripheral circle of the cylindrical body in accordance with a rotary action of the cylindrical body.Type: GrantFiled: May 2, 2002Date of Patent: January 3, 2006Assignee: Konami CorporationInventors: Masaharu Shirasawa, Yoshikazu Tomioka

Patent number: 6886380Abstract: A lock section is mechanically operated by a key provided with identification information to perform a locking or unlocking operation. A receiver acquires the identification information from the key. A checker determines whether the identification information acquired by the receiver matches with pre-stored registration information of the key. A limiter restricts the unlocking operation of the key when the checker determines that the identification information does not match with the registration information.Type: GrantFiled: November 4, 2002Date of Patent: May 3, 2005Assignee: Konami CorporationInventors: Yoshihito Kato, Masaharu Shirasawa

Patent number: 4902263Abstract: A rotating disk is rotated about an upright axis to feed coins placed thereon toward a rotating body. The rotating body is formed with a spiral groove in which the periphery of each coin is inserted and a guide barrel is disposed in such a manner as to maintain the rising coins in the groove in the rotating body. The coin, the periphery of which are engaged in the spiral groove, are received by the guide barrel and lifted in a generally horizontal posture by the rotation of the rotating body and then discharged outside from a discharge port formed at an upper portion of the guide barrel. A rubber-surfaced roller is disposed opposite the rotating body. The roller is adapted to press against the periphery of coins thereby to ensure the insertion of the coins into the spiral grooves.Type: GrantFiled: June 24, 1988Date of Patent: February 20, 1990Assignee: Kabushiki Kaisha UniversalInventors: Tsuyoshi Ito, Masaharu Shirasawa

Patent number: 4802380Abstract: A handle control device for a slot machine in which a handle is operated to start a game, includes a rotatable wheel supported on a fixed shaft for rotation with the handle. Unidirectionally but oppositely rotatable clutch wheels are mounted on the fixed shaft and disposed on opposite sides of the rotatable wheel. An interconnecting member is moved in one or another direction according to the positions of the handle so as selectively to interconnect the rotatable wheel to one or the other of the clutch wheels.Type: GrantFiled: August 31, 1987Date of Patent: February 7, 1989Assignee: Kabushiki Kaisha UniversalInventor: Masaharu Shirasawa
