Abstract
A light source illuminates a developed silver salt photographing film having a magnetic recording portion on which magnetic data is recorded. A light source drive section drives the light source. An image read section reads image data from the film illuminated by the light source. A reproduction section reproduces magnetic data recorded on the magnetic recording portion of the film. A power feeding control section prohibits a power feeding to the light source drive section or reduces an amount of power feeding when the magnetic data is reproduced by the reproduction section.
