ABSTRACT:
A recorder with a pencil pen which contains a plurality of pencil leads therein comprises means for causing a lead chuck mechanism of the pencil lead to hold and release the pencil lead and means for vertically moving a pencil lead displacement mechanism of the pencil pen. Those means are alternately activated by lead feed/eject means to eject a consumed unnecessary pencil lead and drive out a new pencil lead and hold it at a recording position. Since the pencil leads can be automatically ejected and driven out, a recording efficiency is improved and long period continuous recording is attained with a single pencil pen. A lead feed/eject holder is provided to eject a residual lead of the pencil pen, and a processing unit for processing the ejected residual lead is provided. Thus, the recording efficiency is further improved.
