Printing device, and printing cassette including case that houses input part, output part, and transmission mechanism for transmitting drive force from input part to output part

A printing cassette comprising:

• a print tape;
• an input gear;
• an idle gear engaging with the input gear, the idle gear being rotatable with the input gear;
• an output gear engaging with the idle gear, the output gear being rotatable about a rotational axis extending in a first direction with rotation of the input gear and the idle gear, wherein the print tape is conveyable according to rotation of the output gear;
• and
• a case that houses therein at least a part of the print tape, at least a part of the input gear, at least a part of the output gear, and at least part of the idle gear,
• wherein a part of the output gear is positioned outside the case, and
• wherein an entirety of the output gear overlaps the case in the first direction.
