Apparatus and method for reading photographic information for an advanced photo system camera

摘要

An apparatus and a method for reading photographic information for an advance photo system camera utilizes a single optical sensor to record the photographic information on a data disk contained in a film cartridge. The apparatus further includes an information reading device for reading the photographic information and for generating a signal according to the photographic information. A film transport device is also used for rotating a film spool to wind a film into and out of the film cartridge. The apparatus further includes a controller for determining the state of the film cartridge and for setting a stop position of the film spool according to the current state of the film cartridge. The recorded photographic information can be easily read, thus allowing the user to easily determine the state of the film cartridge.
