Abstract
A heater includes: a heat generation unit that generates heat when energized; an electric wire that is attached to the heat generation unit and supplies electric current to the heat generation unit; a ground wire that is attached to the heat generation unit and is grounded; a conductive cover that includes an electrical conductor, is attached to the heat generation unit, and is grounded; and an insulating cover that has an electrical insulating property and at least partially covers the conductive cover.
Claims9
A heater comprising:
- a heat generation unit including:
- a heat generating body that generates heat when energized;
- and a sheath that covers the heat generating body and has a part exposed to an outside;
- an electric wire that is connected to the heat generating body and supplies electric current to the heat generating body;
- a ground wire that is attached to the heat generation unit and is grounded;
- a conductive cover that includes an electrical conductor, is attached to the heat generation unit, is grounded, and is located outside of the sheath, the electric wire and the ground wire extending inside the conductive cover;
- and
- an insulating cover that has an electrical insulating property and at least partially covers the conductive cover.
A heat sealing device comprising a heater, the heater comprising:
- a heat generation unit that generates heat when energized;
- an electric wire that is attached to the heat generation unit and supplies electric current to the heat generation unit;
- a ground wire that is attached to the heat generation unit and is grounded;
- a conductive cover that includes an electrical conductor, is attached to the heat generation unit, and is grounded;
- and an insulating cover that has an electrical insulating property and at least partially covers the conductive cover, wherein the heat generation unit includes:
- a heat generating body that generates heat when energized;
- and a sheath that covers the heat generating body, and
- wherein the insulating cover includes:
- a first insulating covering member that at least partially covers the conductive cover;
- and
- a second insulating covering member that at least partially covers the first insulating covering member and has a smaller stiffness than the first insulating covering member.
A thermal transfer printer that heats an ink ribbon to which an ink is applied and thermally transfers the ink to an object, the thermal transfer printer comprising a heater, the heater comprising:
- a heat generation unit that generates heat when energized;
- an electric wire that is attached to the heat generation unit and supplies electric current to the heat generation unit;
- a ground wire that is attached to the heat generation unit and is grounded;
- a conductive cover that includes an electrical conductor, is attached to the heat generation unit, and is grounded;
- and an insulating cover that has an electrical insulating property and at least partially covers the conductive cover, wherein the heat generation unit includes:
- a heat generating body that generates heat when energized;
- and a sheath that covers the heat generating body,
- wherein the insulating cover includes:
- a first insulating covering member that at least partially covers the conductive cover;
- and
- a second insulating covering member that at least partially covers the first insulating covering member and has a smaller stiffness than the first insulating covering member, and
- wherein the ink ribbon is heated by the heat emitted from the heat generating body.
