PURPOSE:To obtain a thin and inexpensive device by eliminating the plate member of the record extracting device, by limiting the arc-shaped motion of an arm by a table, and by returning the arm and an energizing arm by mutually independent springs. CONSTITUTION:As a caddie case 24 is inserted, an arm 2 rotates clockwise and an energizing arm 3 fitted to the arm 2 through a pin 12 to rotate an index wheel 10 by one tooth. Consequently, a rectangular cam fixed to the index wheel 10 is rotated by one step at some position between latch arms 7 and 8, which perform opening and closing operation. Projections 29 and 30 provided to a table 1 limit the arc- shaped motion of the arm 2 and springs 27 and 28 return the arm 2 and energizing arm 3. Further, a leaf spring 11 is fixed on the table 1 in order to prevent the reversing of the index wheel 10 when the arm 2 is returned. |
