<p>PURPOSE:To provide a stable tension to a tape, by providing a roller rotatable around a pin at one side of a tape running path and a abutting member activated to be abutted on the circumference of the roller. CONSTITUTION:A pin 22 is implanted to one side of a tape running path for a chassis, and a roller 23 rotationable around the pin 22 is provided. A tension regulator post 19 contactably and detachably opposing to the roller 23 is located at the other side of the tape running path, and a mangetic tape 4 is clipped and depressed. The post 19 is implanted to one end of a tension regulator arm 20 supported freely rotatably around a pin 20a implanted to the chassis, and a tensile spring 21 is suspended between a fitting hole 20b provided at the middle of the arm 20 and the pin 22 implanted to the chassis, and the post 19 is activated to the arrowed direction. Thus, a stable tension is given to the tape 4.</p> |
