Abstract

PURPOSE: To change over the timing for starting of counting to that suited for carrier and eliminate miscounting by generating the signal in correspondence to the film carrier selected by selectively mounting one of a plurality of film carriers.
CONSTITUTION: When in the device of retrieving the desired information out of microfilms one of a plurality of film carriers having the means of holding cartridges of mutually different modes and conveying the microfilms in the cartridges to the specified position automatically is selected and used, the opening and closing of AND gates 62, 63 are changed over. When the film detection signal enters from terminal 32n-2, the 3rd timer 60 or 4th timer 61 is operated by this and a flip-flop 65 is set by the output signal thereof to make the mark counting start signal for retrieval in correspondence to the selected film carrier, whereby miscounting may be eliminated.
