Abstract

PURPOSE: To make it possible to not only monitor the running state of a magnetic tape from the external but also display the running quantity, the running direction, etc., by providing a strobe stripe part in the roller which is rotated by running of the magnetic tape.
CONSTITUTION: Strobe stripe part 15 is provided on the lower outside circumference of reversing roller 7. LED16 to irradiate a strobe light to this stripe part 15 is arranged in cover 17. The strobe light from this LED16 is reflected by stripe part 15 and is visible from the external, and strobe stripes are seen stop or flow according to the running state of the magnetic tape. Further, LED19 and a photo detecting element are fitted to frame 18 oppositely while interposing stripe part 15. Since concaves and convexes of stripe part 15 transfer lights to the photo detecting element or break them according to rotation of roller 7, pulse signals according to the running speed of the magnetic tape are outputted from the photo detecting element. The tape running quantity is displayed by integrating and displaying these pulse signals. Then, two sets of conversion means consisting of photo detecting elements and LEDs are provided to make detection of the running direction possible.
