。a light emitting source inserted into the tape cassette; first and second light receiving elements sandwiching the tape on both sides of the tape cassette and facing the light emitting source; and transparent starting and ending ends of the tape. The first and second light-receiving elements detect the presence or absence of light from the light-emitting source that passes through the light-emitting element to obtain first and second output signals, respectively.
- A magnetic recording/reproducing device configured to detect the tape starting end and the tape end using the second output signal, and detect the presence or absence of the tape cassette based on the Okayama power signal.
