Title:
PRESSURE CONTACT MECHANISM FOR THERMAL HEAD
Document Type and Number:
Japanese Patent JP2004314481
Kind Code:
A
Abstract:
To provide a pressure contact mechanism for a thermal head which can prevent deterioration of the recording grade by controlling so as not to make pressure contact force of the thermal head to a body to be recorded excessive while holding adhesiveness between the thermal head and the body to be recorded.
Buffering members 12, 13, and 16, which are made to project on the platen 3 side compared with a heating element 4 and which can relax the pressure contact force of the thermal head 1 to the body 8 to be recorded, are arranged to at least one of clearances between the external position of the thermal head 1 and each heating element 4 so as to be capable of relatively contacting/separating to the platen 3 together with the thermal head 1.
