Abstract
In a case where a first tape cartridge is mounted on a cartridge mounting portion, in which the first tape cartridge that accommodates first tape and a first platen roller having a first roller length and a second tape cartridge that accommodates second tape and a second platen roller having a second roller length larger than the first roller length are mounted, a thermal head that performs printing onto the first tape is pressed against the first platen roller at first head pressing force, and in a case where the second tape cartridge is mounted on the cartridge mounting portion, the thermal head that performs printing onto the second tape is pressed against the second platen roller at second head pressing force larger than the first head pressing force.
Claims20
A head pressing mechanism provided in a tape printing apparatus including
- a cartridge mounting portion, in which a first tape cartridge that accommodates first tape having a first tape width and a first platen roller having a first roller length and a second tape cartridge that accommodates second tape having a second tape width larger than the first tape width and a second platen roller having a second roller length larger than the first roller length are mounted, and
- a thermal head that performs printing onto the first tape and the second tape,
- wherein, when the first tape cartridge is mounted, a first head pressing force is applied to the thermal head to press the thermal head against the first platen roller;
- and
- when the second tape cartridge is mounted, a second head pressing force is applied to the thermal head to press the thermal head against the second platen roller, wherein the second head pressing force is larger than the first head pressing force.
A tape printing apparatus comprising:
- a cartridge mounting portion in which a first tape cartridge that accommodates first tape having a first tape width and a first platen roller having a first roller length and a second tape cartridge that accommodates second tape having a second tape width larger than the first tape width and a second platen roller having a second roller length larger than the first roller length are mounted;
- a thermal head that performs printing onto the first tape when the first tape cartridge is mounted on the cartridge mounting portion and performs printing onto the second tape when the second tape cartridge is mounted on the cartridge mounting portion;
- and
- a head pressing mechanism that applies a first head pressing force to the thermal head to press the thermal head against the first platen roller when the first tape cartridge is mounted on the cartridge mounting portion and applies a second head pressing force to the thermal head to press the thermal head against the second platen roller when the second tape cartridge is mounted on the cartridge mounting portion, wherein the second head pressing force is larger than the first head pressing force.
A head pressing mechanism provided in a tape printing apparatus including a cartridge mounting portion, in which a first tape cartridge that accommodates first tape and a first platen roller and a second tape cartridge that accommodates second tape and a second platen roller are mounted, a thermal head that performs printing onto the first tape and the second tape, and a platen shaft into which the first platen roller and the second platen roller are inserted, the mechanism comprising:
- a first head mechanism that has a pressing portion and presses the thermal head against the first platen roller by means of the pressing portion when the first tape cartridge is mounted on the cartridge mounting portion;
- and
- a second head mechanism that is connected to the thermal head, has a connection portion provided at a position different from a position of the pressing portion in a shaft direction of the platen shaft, and presses the thermal head against the second platen roller by means of the connection portion when the second tape cartridge is mounted on the cartridge mounting portion.
A tape printing apparatus comprising:
- a cartridge mounting portion in which a first tape cartridge that accommodates first tape and a first platen roller and a second tape cartridge that accommodates second tape and a second platen roller are mounted;
- a thermal head that performs printing onto the first tape and the second tape;
- a platen shaft into which the first platen roller and the second platen roller are inserted;
- and
- a head pressing mechanism including a first head mechanism that has a pressing portion and presses the thermal head against the first platen roller by means of the pressing portion when the first tape cartridge is mounted on the cartridge mounting portion, and a second head mechanism that is connected to the thermal head, has a connection portion provided at a position different from a position of the pressing portion in a shaft direction of the platen shaft, and presses the thermal head against the second platen roller by means of the connection portion when the second tape cartridge is mounted on the cartridge mounting portion.
