ABSTRACT:
A tape recorder for repeatedly recording and stopping a recording tape by switching an operating button as a recording button is locked during a recording state. The recorder includes an engaging member for making the recording button engageable with the recording state and a releasing member for driving the engaging member to release the engagement of the recording state by providing a detection member for detecting the presence of the tape in a tape loading chamber biased to a predetermined direction and by moving the detection member in the biassed direction. The biased force of the detection member is utilized as a pressure force for determining the tape position.
