A tape printing apparatus includes a body, and a lid arranged on the body in a hinged-door form, the body having a pocket formed therein for removably loading a cartridge containing a tape-like member as a printing object material. An ejecting mechanism elevates the cartridge when the cartridge is in a state loaded in the pocket. The cartridge is classified into at least a small-height cartridge containing a tape-like member having a small width and a large-height cartridge containing a tape-like member having a large width. The body has a first support member arranged in the pocket for receiving a seating portion of the small-height cartridge in a shallow position in the pocket and a second support member arranged in the pocket for receiving a seating portion of the large-height cartridge in a deep position in the pocket. The first support member is arranged in a position away from the seating portion of the large-height cartridge when the large-height cartridge is loaded in the pocket. The second support member is arranged in a position away from the seating portion of the small-height cartridge loaded when the small-height cartridge is loaded in the pocket.
