PROBLEM TO BE SOLVED: To increase a printable number of sheets under a low-temperature environment in which the capacity of a battery decreases. SOLUTION: An exposure head 30 is set at a position opposed to an exposure aperture 42 of a film pack 41 loaded in a battery-driven simple printer. A first motor 32 is connected via a head moving mechanism 31 to the exposure head 30. A claw 35 which rakes an exposed film 24 is equipped, and at the same time a development roller pair 38 is furnished in the vicinity of a pack discharge opening 44 of the film pack 41. A second motor 37 is connected via a claw moving mechanism 36 and a roller driving mechanism 39 to the claw 35 and the development roller pair 38, respectively. Rotational speeds of the first and second motors 32 and 37 are made to decrease in accordance with a decrease of an environmental temperature in the periphery of the printer. Accordingly, the printable number of sheets can be increased even under the low-temperature environment in which the battery capacity decreases. COPYRIGHT: (C)2007,JPO&INPIT
