Claims

[Scope of utility model registration request]

A mechanical pencil body in which a lead lead holding part housed in an outer cylinder via an elastic member moves back and forth in the axial direction to feed out the lead into the outer cylinder, and other writing instruments are attached to the first barrel. These writing bodies are accommodated in the interior and engaged with a rotary cam whose left and right sides are sloped surfaces with the top as a boundary by the elastic force of the resilient member, and the writing is performed by rotating the rotary cam to either the left or right. In a multi-lead writing instrument in which one of the bodies protrudes and retracts from the barrel opening, a locking part of the mechanical pencil body is formed in the middle of the inclined surface of the rotating cam with which the mechanical pencil body engages,
A second slope is formed on which the mechanical pencil body that has reached this locking part can further slide within a predetermined distance toward the top, and the sliding member of the mechanical pencil body locks on this second slope. 1. A device for ejecting and retracting a writing body of a multi-lead writing instrument including a mechanical pencil body, characterized in that the first slope up to the end is formed to have a gentler slope than the first slope.
