A tape cassette is disclosed including a holding chamber substantially in the shape of an upper case G having a downward branch including a tape entrance and an upward branch including a tape exit. The cross-sectional area of the downward branch increases to a maximum and then decreases to a minimum, the minimum occurring at the junction between the upward and downward branches. The walls defining the downward branch are also stepped providing a sudden increase in the cross-sectional area of the branch, allowing the tape to fall easily therethrough.
