Abstract: PURPOSE:To prevent a sheet for an image file from being loaded incorrectly in the reader and failing to read an image and its accompanying information normally by deciding whether or not the sheet for the image file is loaded properly according to whether information is read by an information read means. CONSTITUTION:When the sheet 1 for the image file mounted on a tray 8 is inserted into a TV photoplayer 7, the head 16 reads information out of an information recording part 6.
