Abstract
A photo film cassette includes a spool lock member, which prevents a spool from rotating when a rotatable cassette shutter for a photo film passageway is in a closed position. The spool lock member includes a base portion. A first arm extends from the base portion toward the cassette shutter, and shifts in a first direction in response to rotation of the cassette shutter toward the closed position. A second arm extends from the base portion toward the spool, and blocks rotation of the spool by shifting in the first direction with the first arm. The first and second arms have respectively first and second end portions opposite to the base portion. The first and second end portions have a greater width or thickness than an interval between the first and second arms, and are prevented from accidental entry between the first and second arms of another spool lock member before being assembled.
