Thermal head for printer
A printer includes a thermal head, an electrical connector capable of being connected to and disconnected from the thermal head, and a head cover of the thermal head. The head cover moves between a first position and a second position different from the first position to connect and disconnect the thermal head and the electrical connector.
1. A thermal head for a printer, the thermal head comprising:
a heater element configured to print information;
a female electrical connector configured to mate with a male electrical connector; and
a connection unit limiter which projects from the thermal head to align the female electrical connector and the male electrical connector with each other.
2. A thermal head as set forth in claim 1 , wherein the connection unit limiter comprises:
a first limiter configured to be adjacent to a head bracket; and
a second limiter configured to mate with a portion of the male electrical connector.
3. A thermal head as set forth in claim 1 , wherein the connection unit limiter is screw-shaped in cross-section.
4. A thermal head as set forth in claim 1 , wherein the connection unit limiter comprises a narrow portion and a larger head portion.
5. A thermal head for a printer, the thermal head comprising:
a heater element configured to print information;
a female electrical connector configured to mate with a male electrical connector; and
two depressions configured to receive projections of a head bracket.
6. A thermal head as set forth in claim 5 , wherein the two depressions are configured to receive the projections such that the thermal head is held.
7. A thermal head for a printer, the thermal head comprising:
a heater element configured to print information;
a female electrical connector configured to mate with a male electrical connector; and
at least one depression configured to receive a projection of a head bracket.
8. A thermal head for a printer, the thermal head comprising:
a heater element configured to print information;
a female electrical connector configured to mate with a male electrical connector; and
two depressions configured to receive projections of a head bracket to restrict the thermal head from moving in a feeding direction of a print medium, a top portion of the two depressions being spaced from a top edge of the thermal head farther than the heater element is spaced from the top edge of the thermal head.
9. A thermal head for a printer, the thermal head comprising:
a heater element configured to print information;
a female electrical connector configured to mate with a male electrical connector; and
a groove on a top surface of the thermal head configured to be gripped by at least one of a finger, fingernail, thumb or thumbnail.
10. A thermal head for a printer, the thermal head comprising:
a heater element configured to print information;
a female electrical connector configured to mate with a male electrical connector; and
wherein a top surface of the thermal head is shaped to be gripped by at least one of a finger, fingernail, thumb or thumbnail.
11. A thermal head for a printer, the thermal head comprising:
a heater element spaced from a top edge of the thermal head and configured to print information;
a female electrical connector configured to mate with a male electrical connector;
a connection unit limiter which projects from the thermal head, from a center portion of the thermal head in a width direction, the connection unit limiter comprising a head portion configured to be adjacent to a head bracket and a narrow portion configured to mate with a portion which extends from the male electrical connector; and
two depressions configured to receive projections of the head bracket to restrict the thermal head from moving in a feeding direction of a print medium, each of the two depressions being outboard of the connection unit limiter in the width direction, a top portion of the two depressions being spaced from the top edge of the thermal head farther than the heater element is spaced from the top edge of the thermal head.
12. A thermal head as set forth in claim 11 , further comprising a groove on a top surface of the thermal head configured to be gripped by at least one of a finger, fingernail, thumb or thumbnail.
13. A thermal head as set forth in claim 11 , wherein a top surface of the thermal head is shaped to be gripped by at least one of a finger, fingernail, thumb or thumbnail.
14. A thermal head as set forth in claim 11 , further comprising two additional depressions configured to receive projections of the head bracket.
