Abstract: A labeling method and apparatus for putting a label onto a periphery of a photo film cassette, while conveying the photo film cassette from a label applying position to a label securing position while supporting the photo film cassette in a posture. In a label applying unit, a label is partly peeled from a label tape by turning the label tape around a separator member. While the peeled end portion of the label is hanging down from the separator member, the photo film cassette is moved toward the end portion of the label to stick the end portion to a forward portion of the periphery of the photo film cassette. As the photo film cassette is moved further toward a label securing unit, the label is completely peeled off. The label securing unit presses and rolls a pressing roller on the label along the periphery of the cassette to securely stick the label to the periphery.
