Abstract
PURPOSE: To reduce the non-recording and non-reproduction time at operation conversion, by containing and fixing the optical system for reader tape detection at a part of the erase head.
CONSTITUTION: The fine light emitter 5 is provided in the reference pin 2 placed on the tape deck, and the transparent guide 4 guiding the light from the fine light emitter 5 and the photo detector 6 consisting of the photo electric elements such as cadmium sulfate photo diodes and photo transistors are provided in the erase head 1 providing the erase magnetic field production coil 8. Thus, when the tape 3 is running while contacting with the erase head 1, the tape 3 passing through the erase head 1 ends the opaque part coated with magnetic film and comes to the transparent reader, then the light from the fine light emitter 5 is detected at the photo detector 6, and the automatic stop and inversion of tape recorder is made to achieve desired object.
