    • A protector block is movable in a direction in which a key K can be inserted, and first engaging portions which engage each other when the protector block is pushed in are formed between the protector block and an outer lock cylinder. A crankshaft is movable in the direction in which the key K can be inserted, and second engaging portions which engage each other when the crankshaft is pushed in are formed between the crankshaft and the outer lock cylinder. When an object in place of a key is inserted into a key insertion hole and attempts are made to forcibly turn the object while pushing the object, the first engaging portions between the protector block and the outer lock cylinder engage each other, preventing the crankshaft from being turned. When attempts are made to turn an inserted object while pulling the object, the second engaging portions between the crankshaft and the outer lock cylinder engage each other, preventing the crankshaft from being turned. In combination with tumblers preventing the crankshaft from being turned, the above structure makes it highly difficult to unlock the handle lock device.
    • 保护器块可以在可以插入钥匙K的方向上移动,并且在保护器块被推入时彼此接合的第一接合部分形成在保护器块和外部锁芯之间。 曲轴可以在键K可以插入的方向上移动,并且在曲轴被推入时彼此接合的第二接合部分形成在曲轴和外锁定缸之间。 当将物体代替钥匙插入钥匙插入孔中时,试图在推动物体的同时强制地转动物体,保护器块和外锁定筒之间的第一接合部分彼此接合,从而防止曲轴 被转身 当试图在拉动物体的同时转动被插入的物体时,曲轴和外锁定筒之间的第二接合部彼此接合,防止曲轴转动。 结合防止曲轴转动的翻转开关,上述结构使得解锁手柄锁定装置非常困难。

    • An impact printer has a type drum, a plurality of hammers, a type drum gear secured to a shaft of the type drum, and a gear train including a drive gear and an intermediate gear engaged with the drive gear and type drum gear for driving the type drum. A lever is provided to rotate about a shaft of the drive gear. The intermediate gear is rotatably supported on the lever at one end thereof, and a spring is provided for urging the lever in the direction that the intermediate gear engages with the type drum gear. The rotational direction of the type drum gear is such that the rotation of the type drum gear causes the intermediate gear to revolve around the drive gear to brake the type drum.
    • 冲击式打印机具有类型鼓,多个锤,固定到型鼓的轴的类型鼓齿轮和包括驱动齿轮和与驱动齿轮啮合的中间齿轮的齿轮系和用于驱动 型鼓。 提供杠杆以围绕驱动齿轮的轴旋转。 中间齿轮在其一端可旋转地支撑在杠杆上,并且设置弹簧以沿中间齿轮与型鼓齿轮接合的方向推动杆。 类型鼓齿轮的旋转方向使得类型鼓齿轮的旋转使得中间齿轮围绕驱动齿轮旋转以制动型滚筒。
