Claims

[Scope of utility model registration request]

(1) A fixed or rotatable support placed on the tape running path and in contact with the tape; an arm provided so as to be movable toward the tape running side at a position where the tape running path is sandwiched between the support; a pressing piece made of a material with a large friction coefficient, which is provided on the arm and pinches the tape with the support; a tape tension detection protrusion, which is provided on the arm and whose tip is in contact with the tape; A tape running device comprising: a spring that biases the arm; and a damper that damps vibrations of the arm.

(2) The arm is rotatably supported around a fulcrum so that it can move forward and backward toward the tape running path by rotation, and the distance from the fulcrum to the tape tension detection protrusion is greater than the distance from the fulcrum to the pressing piece. The tape running device according to claim (1) of the utility model registration claim, in which the length of the tape is longer than the length of the tape running device.
