プレコーダ。[Claims for Utility Model Registration] A recording and reproducing unit and a tape holding drive unit are provided inside a fixed reel having an endless loop-shaped tape roll, and the tape is The tape is held and driven by the tape holding drive unit, pulled out from the innermost periphery of the tape winding of the fixed reel, passed through the recording/playback unit, where recording and playback is performed, and then sent out from the tape holding drive unit. In an endless tape recorder configured such that tape is wound around the outermost circumference of a fixed reel, the tape is wound around the outermost circumference of a fixed reel. What is claimed is: 1. An endless tape recorder with a tension display mechanism, comprising: a tension display section for detecting tension; and a display drive circuit for driving the tension display section in accordance with an output of the tension detection mechanism.
