    摘要: In the tape position detecting device, the relative position data and absolute position data of the reference points are stored, and with respect to an arbitrary point, the first tape position data is detected by using the relative position data. The tape movement data from a reference point to the arbitrary point which is obtained using the absolute position data is added to the absolute position data of the reference point to detect the second tape position data. Depending on the difference between the first and second tape position data, the first or second tape position data is transmitted as the tape position data output. Hence, with the tape position detecting device, the tape position data can be detected much more accurately than with the conventional device in which it is detected by using the relative position data or absolute position data only.
