What is claimed is: 1. A magnetic tape detecting device, further comprising: a reflecting plate on the other side of the tape path for reflecting light projected from the light projecting section to a light receiving section. (2) In a magnetic tape drive device equipped with an automatic loading mechanism that guides the magnetic tape loaded on the supply tape reel to the take-up tape reel, tape detection detects whether or not a magnetic tape exists in the tape path. and when the magnetic tape is being driven in the feeding direction and the detection output of the tape detection device changes from a tape detection state to a tape non-detection state, the magnetic tape is not correctly mounted. A magnetic tape drive device characterized by comprising a control device that determines that.
