Tape printing device

A tape printing device comprising:

• a cartridge mounting portion in which are mounted a tape cartridge accommodating a tape and a platen roller;
• a platen shaft that engages with the platen roller;
• a thermal head that prints on the tape sandwiched between the thermal head and the platen roller engaged with the platen shaft;
• a head support shaft that supports the thermal head;
• a head moving mechanism that moves the thermal head between (i) a sandwiching position where the thermal head sandwiches the tape with the platen roller and (ii) a separating position where the thermal head is separated from the platen roller;
• a head holder that has a rotating shaft and that is configured to hold the thermal head to rotate about the rotating shaft so that the thermal head follows the platen roller after the thermal head is moved to the sandwiching position;
• and
• a pressing member that is provided and configured to rotate about the rotating shaft together with the thermal head and that presses the thermal head against the platen roller after the thermal head is moved to the sandwiching position,
• wherein the pressing member has a convex portion that protrudes toward the thermal head and that presses the thermal head against the platen roller, and
• wherein the platen shaft and the head support shaft each have a cantilevered structure and are thus each supported only in a second direction, which is one of axial directions of the platen shaft and the rotating shaft.
