发明名称 FILM CASSETTE
摘要 PURPOSE:To facilitate the unloading of a film cassette out of a camera body, by providing a catch member which is pushed inward by the closing action of a rear cover to be stored into the main body of the film cassette. CONSTITUTION:When a film cassette 10 is stored into a film cassette storing room 22, a spool shaft 46 of a camera main body 14 engages with a roll-up shaft 40 of the cassette 10. Thus the rotation of the shaft 46 can be transmitted to the shaft 40. Under these conditions, a rear cover 23 is closed to shut off the room 22. Thus the lower face of the cover 23 pushes a catch 44 toward a recess part 46 formed on a bottom surface 42 of the cassette 10 in accordance with the closing action of the cover 23. As a result, the catch 44 turns centering on the junction part and never prevents the closing action of the cover 23.
