<p>PURPOSE:To miniaturize the overall size of a device and to expand the using range by cutting the power source of a direct current motor and stopping the head of a tape at a starting position when the cut line of an endless tape contacts with a sensor. CONSTITUTION:In the inside of an endless tape 8 between a capstan 6 and a tape guide 10, a conducting sensor 19, in which a positive plate 17 and a negative plate 18 are separated a little, is arranged so that the plates 17 and 18 can be pressured to the rear surface at the inside of the tape 8. A cut line 20 is provided at the suitable place of the tape 8, a weak current flows at the rear surface of the inside of the tape 8, the cut line 20 contacts with the sensor 19, and then, the power source of a direct current motor 2 is cut and the head of the tape 8 is stopped at the starting position.</p> |
