<p>PURPOSE: To obtain a transfer position detector for a recording medium tape capable of obtaining a highly reliable detection signal and also reducing the number of components. CONSTITUTION: A white colored disk 30a is integrally provided on a rotary shaft 30, and plural through holes 31 successively arranged along the circumferential direction are formed on this disk 30a, and further a black fiber member 32 such as a felt, etc., provided at the upper surface side of the disk 30a so as to cover each hole 31, and a light emitting/receiving device 26 having a part for emitting the light toward the lower surface of the disk 30a and a part for receiving the reflected light of the disk 30a are furnished in the detector. And, the constitution is made so that the tape transfer position is detected by an output signal of the light emitting/receiving device 26 corresponded to the rotation of the disk 30a.</p> |
