Abstract: PURPOSE: To easily instruct the number of prints to a laboratory by deciding whether loaded film is negative film or positive film and instructing the number of prints in accordance with the decided result. CONSTITUTION: Whether the number (ns ) of photographing times when a main switch is turned on is zero or not is judged (S36). When photographing is not performed yet, the kind of the film is judged by a data read circuit (S37). When it is the negative film, the initial value of the number of prints npo =1 is set (S39). When it is not the negative film, that is, it is the positive film, the initial value of the number of prints npo =0 is set (S41). Next, whether it is releasable or not is judged. When it is possible, a display circuit displays that a main power source is turned on and turning on a first stage pushing switch S1 is decided (S43). In the case the switch S1 is not turned on and the setting of the number of prints is changed, the number (n1 ) of prints changed to the number (npo ) of prints is inputted.  When turning on the switch S1 is detected, operation is shifted to the next one.

Abstract: PURPOSE: To provide a method for continuously producing a polycarbonate resin, capable of reducing stamper stains generated on the molding of optical disks, compact disks, etc., and capable of preventing the generation of white spots on molded products under the environments of high temperature and high humidity. CONSTITUTION: A method continuously producing a optical polycarbonate resin comprises reacting the mixed solution of an aqueous alkali-solution of a dihydric phenol with an organic solvent with phosgene, while maintaining an oil-in-water type suspension state, converting the produced polycarbonate oligomer reaction solution into a water-in-oil type emulsion, adding a polymerization catalyst to the emulsion, and subsequently repeating at least once a step of passing the mixture through an orifice at a velocity of >=100cm/s and then aging the passed mixture for 5-600sec to complete the polymerization reaction. Thereby, the production of monomer oligomers can be suppressed, and the residual amount of the terminal chloroformate groups can be reduced. The produced polycarbonate resin is thus useful as a raw material for optical disks and compact disks which require high qualities.
