Abstract: PURPOSE:To measure required light among emitted light, transmitted light, scattered light and fluorescence, by utilizing the movement of a light measuring cell to an emitted light path, and using the combination of a light-path selecting mechanism and a filter inserting mechanism. CONSTITUTION:Transmitted light (or emitted light) passes through a hole 9 of a light converging mirror 8. The light is reflected by a light converging element 17' and further reflected by a light-path switching mechanism (mirror) 18'. The light hits a photoelectric detector 6. On the other hand, scattered light (or fluorescence) is reflected by the light converging mirror 8 and directed toward the photoelectric detector 6 by a light converging element 17. However, the light is shut OFF or reflected to the ouside of the light path by the light-path switching mechanism 18', and does not reach the photoelectric detector 6. But the scattered light (or fluorescence) reaches the photoelectric detector 6 by driving and moving the light-path switching mechanism 18' to the outside of the light path by a suitable means. Meanwhile, under this state, the transmitted light (or emitted light) reflected by the light converging element 17' advances straight and does not reach the photoelectric detector 6.

Abstract: PURPOSE:To enable to enhance accuracy in protruding the leading end of a color and to save a film ribbon, by a method wherein bar codes provided on a film ribbon are detected by two detecting parts provided in a carriage, and feeding of the ribbon is controlled. CONSTITUTION:The film ribbon 5 is moved in the direction of an arrow, and the bar codes 9, 10, 11 provided thereon first pass by a reflection-type photo-sensor 15, and then pass by a photo-sensor 16. In this case, at the bar code parts, a low-level signal is outputted three times in the case of Y, two times in the case of M and one time in the case of C. In the case of a color film ribbon, light is not reflected by a trailing end part of the ribbon, and a low-level signal is continuously outputted. On the other hand, in the case of a black film ribbon, a high-level signal is continuously outputted. The signal is processed by a controlling part 17, and printing is started at a position at a predetermined distance from the bar code. Accordingly, the accuracy in protruding the leading end of a color is enhanced, the film ribbon can be saved, and it is also possible to stop the feeding of the film ribbon by detecting the trailing end of the ribbon by the detecting part.
