Abstract
PURPOSE:To make it possible to apply load automatically and on a step-by-step basis, by making a combination of a forward-and-back-ward-rotatable motor, a voltage generator which generates voltage on a step-by-step basis, and a timer. CONSTITUTION:Tip of a lever 2 is connected to a forward-and-backward-rotatable motor 16 through a spring 10 and a load meter 8. And, a load applied onto the lever 2 is taken out by a load meter 8 as an electric signal V1 and put into a comparator 21. On the other hand, an output V2 of a voltage generator 22 is put into the comparator 21, voltages V1 and V2 are compared, and by the result, the motor 16 is turned forwards or backwards, and stroke rod is shifted through a worm wheel 14 to control load on the lever 2 until V1 becomes equal to V2. And then, voltage of the voltage generator 22 is raised by 1 step by output of a timer 23, as a result, the motor 16 is again driven to vary the load applied on the lever 2. It is possible, by doing so, to apply load onto the lever 2 automatically and on a step-by- step basis.
