Abstract
A pen recorder is provided with a holder base and a hammer base which are movable along a platen. A plurality of pens are mounted in parallel on the holder base. A hammer for pressing any one of the pens is mounted on the hammer base. One of the bases is driven by a driving means such as a pulse motor. Moreover, a lock mechanism is provided for connecting the holder base and the hammer base. Thus, it becomes possible to select the pen to be pressed by the hammer through the movement of relative position between the bases effected by the lock mechanism.
