<p>PURPOSE:To enable a tape operation resulting the steep change of tape speed to be performed by providing a gain control means controllable a gain based on the output of a tape inertia setting means and a reel inertia setting means. CONSTITUTION:The title device is constituted of a tension detector 6, a tensile force control means 13, and a reel motor 3, and the tension detector 6 is connected to the reel motor 3 mechanically via a tape 2. Also, the tensile force control means 13 is provided with a tensile force reference means 14, a comparison means 15, the tape inertia setting means 18, the reel inertia setting means 19, the gain control means 16, and a motor driving means 17. And the state of the gain control means 16 is varied by the output of the tape inertia setting means 18 and the reel inertia setting means 19. Therefore, appropriate gain compensation is applied on a control system for tensile force corresponding to the change of the inertia moment value of the whole of a tape reel 1. In such a way, it is possible to perform the tape operation resulting the steep change of the tape speed as to supply large disturbance to the control system for tensil force.</p> |
