Abstract

A tape recorder comprises a tape run stop detection lever and a spring. The lever is provided with a detection pin which is urged in one direction by a rotation of a right side reel rest to be engaged with a cam idler. When the detection pin is engaged with the cam idler at the stop of the right side reel rest, the lever is moved in one direction by the engagement between the cam idler and detection pin. The spring produces at the movement of the lever an urging force acting in the direction opposite to said one direction. The lever is moved in the direction by the engagement between the cam idler and detection pin to detect the stop of the tape run. The cam idler is temporarily prevented from being coupled to an idler section of a flywheel and is rotated by the spring in the direction opposite to said one direction to release the engagement.
