PRINTER COVER LOCKING MECHANISM

摘要

A printer cover locking mechanism has a reduced number of parts and may be assembled in a small space, by simplification of a print head (thermal head (13)) mechanism, a cover lock (27) mechanism relating to opening and closing of an opening and closing cover (3), and a heat dissipation mechanism for a print head (13). The cover lock (27) also serves as a heat dissipation plate. A printer cover locking mechanism includes the opening and closing cover (3) that opens and closes with respect to a printer housing (2). A print head (13) for printing on print paper (continuous label body (4)), a platen roller (14) for feeding a print paper (4) by sandwiching the print paper (4) between the platen roller (14) and the print head (13), and a cover lock (27) for causing the print head (13) to contact with and separate from the platen roller (14) by engaging with and disengaging from the platen roller (14), respectively. The print head (13) is attached on the cover lock (27), and the cover lock (27) is capable of dissipating heat generated from the print head (13).

主权项

1. A printer cover locking mechanism comprising:
a printer housing; an opening and closing cover configured to open and close with respect to the printer housing; a print head attached to one of the printer housing or the opening and closing cover, the print head configured for printing on print paper loaded into the printer housing; a platen roller attached to another of the printer housing or the opening and closing cover, the platen roller configured for feeding the print paper by sandwiching and rotating the print paper between the print head and the platen roller; and a cover lock configured to cause the print head to contact with the platen roller by engaging with the platen roller and configured to cause the print head to separate from the platen roller by disengaging from the platen roller, the cover lock being attached to the print head, the cover lock being configured for allowing dissipation of heat generated from the print head.
