Knock type writing instrument |
摘要 |
A slide body (6) is arranged in a cut-away portion of a holder (1) under a clip (2a) so as to not hinder writing or portability, and a safety mechanism is constituted so as to be engaged with the clip (2a). Due to functions of a knock rod cam (4a) of a knock rod (4) and a knock cam (3a) of a rotor (3), further, the rotor (3) is rotated and moved forward responsive to each knocking operation, a refill (7) is brought to a writing position and a holding position alternately responsive to each knocking operation due to a cam mechanism provided in the inner wall of an inner cylinder (2) and a reactive force of a spring (5). A slide body cam (6a) provided on the slide body (6) is incorporated in a portion of the cam mechanism so that the knock type writing instrument thrusts the pen point out, by one knock even after the safety operation. |
