Abstract: PROBLEM TO BE SOLVED: To obtain a suitable viscosity by cooling a mixture of a mixed fatty acid ester of cellulose with a solution containing a solvent selected among specified ketones, specified esters and specified ethers and an alcoholic solvent and heating the cooled mixture. SOLUTION: A mixed fatty acid ester of cellulose (e.g. cellulose acetate propionate) satisfying formulas I to III (wherein DSace is the degree of substitution of hydroxyl groups by acetyl groups, and DSacy is the degree of substitution of hydroxyl groups by 3C or higher acyl groups) and having an average degree of polymerization of 350-800 is prepared. Next, 10-40wt.% obtained mixed ester is mixed with 60-90wt.% mixed solvent containing 40-70wt.% solvent selected among 3-12C ketones (e.g. acetone), esters (e.g. methyl acetate) and 3-12C ethers (e.g. dimethoxymethane) and 30-60wt.% 2-8C alcohol (e.g. ethanol). The resulting mixture is cooled to -100 to -10 deg.C to form a solid, and this solid is molten by heating to 0-100 deg.C to obtain a uniform solution. This solution is cast over a support and formed into a film by the evaporation of the solvent.

Abstract: PURPOSE:To shorten the processing time of collecting operation for collecting all paper currency, stored in the device, into a replenishment cassette and to improve the operability by providing a means which performs 2nd feeding-out control for providing minimum intervals of continuous feeding-out operation. CONSTITUTION:When the tail end of separated paper currency exits from a 1st sensor, a motor M is driven again to feed next paper currency out.

This is 1st feeding- out control. The 2nd feeding-out control is the same up to the stop of the motor M when the 1st sensor is reached, but next driving timing is set to the point of time when a 2nd sensor is passed and next paper currency is fed out successively when the tip of the leading paper currency advances by nearby the same distance L3 as the paper currency length.
