PURPOSE:To constitute a small-sized, easy-to-handle device by moving a specified card storage truck among trucks, arranged radially in a cylindrical card rack, to an outlet, and pushing cards out. CONSTITUTION:At the cylindrical circumference of a card rack 1, trucks 2 wherein information cards such as name cards are sorted and stored are provided radially. A DC motor 3 rotates the card rack 1 through a rubber roller 4. A rack commutator 11 is fixed to a housing 6 while corresponding to respective trucks 2, and resistors are connected between adjacent commutator pieces 11, thus forming a bridge circuit wherein position difference of respective trucks 2 in the rotating direction are converted into resistance value differences. Then, DC power source terminals are selected adequately with keys 12 on a keyboard 8 constituted corresponding to the respective trucks 2. The output terminal 13 of the bridge is connected to the brush of the motor 3, and rotated until the bridge is balanced. Cards are discharged from an outlet 7 through a plunger 9 and a push rod 10. Thus, the cards are retrieved easily. |
