PROBLEM TO BE SOLVED: To accurately judge the quality of a card feeder by measuring the feed force of the card feed mechanism built in a card processing apparatus or the like. SOLUTION: The portable card feed force measuring instrument 1 measures the feed force of a card C when the card C is fed by the card feed mechanism 31 and has a feed force measuring instrument 2 such as a spring balance or the like. The feed force measuring instrument 2 is fixed to a base to hold the card C connected to the feed force measuring instrument 2 so as to make the same freely slidable in an advance and retreat direction. A control member 23 is held by the base 10 over a knob opening 5 and controls the movement of a measuring knob 8 in the advance and retreat direction and the feed force measuring instrument 2 sets the maximum measured value of measurable feed force. |
