PROBLEM TO BE SOLVED: To effectively prevent the unexpected rotation caused by the malfunction, by permitting the driving of a classification storing part when both of the first and second switches are operated, and rotating the classification storing part in a direction directed by the switch, on the basis of the result of the discrimination that which switch is operated first. SOLUTION: The rotation of a classification box is permitted under a condition that the both of a left switch 20 and a right switch 21 are operated. Whereby the insertion of a hand into the classification box can be prevented, because the switching operation is performed by the both hands during a time when the classification box is rotated and driven by the switching operation when a slip is taken out, or the wrong rotation and driving of the classification box can be prevented because the operation is performed by the both hands. Further a rotating direction of the classification box can be controlled on the basis of that which one of the left switch 20 and the right switch 21 is operated first. The operating condition of the left switch 20 and the right switch 21 is monitored by a program control, to control the rotation of the classification box. |
