Abstract

PURPOSE:To achieve the miniaturization of a pressure-contacting solenoid by displacing a pinch roller to the capstan approach position via link device through utilization of a magnetic tape loading device. CONSTITUTION:When loading operation of a tape is started, a worm wheel 10b moves in the arrow C direction and the pin 23 fixed thereto engages to an arm 24 and causes a rod 25 to move in the arrow D direction, hence an interlocking rod 27 moves in the arrow E direction, thus causing a pinch roller arm 21 to turn in the arrow F direction. In the position where the movement of the rod 25 ends, a pinch roller 4 approaches to a capstan 5, thus displacing in the position immediate before the start of pressure conract. Next, if the completion of automatic loading is detected with a switch 19 and a solenoid 20 is operated, the roller 4 makes pressure-contact to the capstan 5 and the magnetic tape runs. At this time the pressure-contact force of the roller 4 is increased further by elongating a spring 34. Since in this way the solenoid may be utilized only for the pressure-contact of the pinch roller, this may be miniaturized.
