PURPOSE:To accurately feed the film which is required for analytic measurement by a constant quantity into an analytic area by fixing a used film and an unused film alternately and moving film cassettes alternately and associatively with the fixation. CONSTITUTION:A clamp member 46 is moved up after analytic operation in an analytic area 4 to clamp the test film 31 with the member 46 and a supporting member 45. Then a support base 12 is moved left and then the film 31 is pulled out of an unused film cassette 30 by the movement distance of the base 12 and conveyed to the analytic area 4. Then the reel 34 of the cassette 30 is fixed and the member 46 is lowered to release the film 31 from being fixed, thereby taking up the film 31 around a reel 41 while moving the base 12 right. This operation is repeated to accurately send the test film intermittently by the constant quantity required for analytic measurement. |
