Abstract
A pen recorder comprising a pen which is adapted to be placed in contact with a recording paper, a return spring which is capable of energizing a pen so that it is separated from the recording paper and a push-out means which pushes the pen so that it can be placed in contact with the recording paper. This push-out means includes a push-lever urging the pen towards the recording paper against a spring force larger than that of the return spring. During the printing operation, this push-lever is separated from the roller, while during the waiting condition, it engages the roller. Accordingly, stabilized pen feed rate and contact pressure of pen can be realized during printing operation.
