PROBLEM TO BE SOLVED: To provide a composite feeding implement for simply conducting a knocking operation of a writing barrel by using the barrel for feeding a writing lead by the knocking operation. SOLUTION: A knocking barrel 24 is arranged at a rear end of a barrel 10, and an oscillating member 30 is mounted in the barrel 24. A cam 30a connectable to a slider 18 is extended forward from a tip of the barrel 24 at the member 30. And, when the slider 18 is locked to the tip of the barrel 24, it is held at an end of a slot 12b, and the cam 30a is oscillated to be engaged with the other slider 18. When the other slider 18 is forwarded, the cam 30a engaged with it disengages the barrel 14 locked to the end of the barrel 14. The barrel 14 is knocked in the state that the slider 18 is locked to the end of the barrel 24, thereby knocking a mechanical pencil barrel 14. |
