CONVERTIBLE TYPE CYLINDER LOCK
PROBLEM TO BE SOLVED: To provide a key-code convertible type cylinder lock which can prevent illegal unlock in a case such as when a manufactured game machine is transported to a game parlor.SOLUTION: In a convertible type cylindrical lock, a display window 13 and a pin hole 12b are formed in an outer cylinder 1, and a turn display member 14, in which a display part 14a thereof is arranged to be displayed in the display window, is arranged between an inner cylinder 2 and the outer cylinder 1. A pin hole 14b is formed in the turn display member. When turning the inner cylinder 2 to a code conversion position by a key, a pin tip 15b of a cutting pin 15 inserted into a pin insertion hole 24 of the inner cylinder 2 is fit into the pin hole 14b of the turn display member. When returning the key together with the inner cylinder to a normal state from the conversion position, the turn display member is turned to a normal position together with the inner cylinder, the pin tip of the cutting pin is fit into the pin hole 12b of the outer cylinder 1. When the inner cylinder is turned next time, the pin tip of the cutting pin is cut off, thus the display part of the turn display member is located inside the display window, thereby fixedly displayed.SELECTED DRAWING: Figure 1
【課題】製造された遊技機が遊技機ホールに輸送される際などにおいて、不正解錠を防止することができるキーコード変換型の変換式シリンダ錠を提供する。【解決手段】外筒１に表示窓１３とピン孔１２ｂが設けられ、表示窓に表示部１４ａを表示可能に設けた回動表示部材１４が内筒２と外筒１の間に配設される。回動表示部材にはピン孔１４ｂが設けられる。キーにより内筒２をコード変換位置まで回したとき、内筒２のピン挿入孔２４に挿入した切断ピン１５のピン先端部１５ｂが回動表示部材のピン孔１４ｂと嵌合する。キーを内筒とともに変換位置から通常状態に戻すとき、回動表示部材が内筒とともに通常位置まで回動し、切断ピンのピン先端部は外筒１のピン孔１２ｂに嵌合し、次に内筒を回わしたとき、切断ピンのピン先端部が切り離され、回動表示部材の表示部は表示窓の内側に位置し固定的に表示された状態となる。【選択図】図１
