Abstract
A film magazine is loaded. A fork capable of engaging with a spool is caused to engage the spool and is rotated to perform film initial sending. Then, an engaged state of the fork with the spool is detected by a fork switch. A rotational quantity of the fork is detected from the point when the fork completely engages the spool. Thus, more accurate film initial sending quantity is measured. If an error is made in the sending operation and predetermined quantity of film initial sending cannot be sent, film is rewound on the basis of film sent quantity. Accordingly, an operation of film initial sending can be performed again.
