Abstract
A film cassette comprises a spool supported inside a shell for rotation to thrust a filmstrip coiled about the spool to the exterior of the shell whether the filmstrip is unexposed or is partly exposed, and a film exposure status indicator secured to the spool for rotation from an unexposed position for providing a visible indication that the filmstrip is unexposed to respective partly exposed and fully exposed positions for providing visible indications that the filmstrip is only partly exposed or is substantially exposed. A spool lock is supported for movement to arrest the spool with the film exposure status indicator in the unexposed, partly exposed or fully exposed position, and to release the spool. According to the invention, the spool lock includes a film speed indicator for providing a detectable indication of the speed of the filmstrip which is not detectable when the spool lock is arresting the spool and is detectable when the spool lock has released the spool.
