Abstract

A key board and key tooth combination in the key-press type mechanical code operating mechanism is composed of a key board, a key tooth, a combination sheet, a slider and a cardboard. The left wing of the combination sheet is inserted in the long hole of the key board, the right wing of the combination sheet is inserted in the slot of the slot hole of key tooth. The elbow of the key tooth acts for blocking or non-blocking for movement of the main movement member. When the right wing is inserted in the lower slot of the key tooth, the elbow in the original position can not block movement of the main movement member, that is non-coded key. When the right wing is inserted in the upper slot of the key tooth, the elbow in the original position can block movement of the main movement member, that is coded key. The change of the position of the key tooth slot hole, where the right wing is inserted therein, is carried out by movement of the slider so that the operation of changing code can be carried outside the mechanism.
