A writing implement, having a writing-core arrangement arranged in a shaft part, has a rotary mechanism, by means of which the writing-core arrangement can be moved into the writing position. The rotary mechanism has an adjusting element (20) with a guide curve (22, 23, 24) and is rotatable relative to an actuating element (30) which has a support projection (32) engaging with the guide curve (22, 23, 24). When using a writing-core arrangement in the form of a ball-point writing-core, its rear end face rests against a first support surface (33) of the actuating element (30), and the support projection (32) can be engaged with one support portion (24) of the guide curve. The actuating element (30) is of bush-type construction and has a blocking part (40) which can be displaced into a blocking position counter to spring force and is moved into the blocking position, when using a propelling pencil mechanism, by its actuating pin (16, 17), with the result that the support projection (32) cannot be engaged with the support portion (24) of the guide curve (22, 23, 24).
