Clamp mechanism and related printer

摘要

A clamp mechanism for fixing a printing medium is disclosed in the present invention. The clamp mechanism includes a base, a drum pivotably disposed on the base, a frame disposed on the drum, a clamping component movably disposed on the frame for clamping an end of the printing medium with the drum, and a resilient component disposed between the frame and the clamping component for pressing the clamping component on a surface of the drum so as to clamp the end of the printing medium.

主权项

1. A clamp mechanism comprising:
a base; a drum pivotably disposed on the base; a frame disposed on a lateral surface of the drum, an opening being formed on the frame; a clamping component movably disposed inside the opening of the frame along a longitudinal direction of the opening to be suspended over a support surface of the drum so as to switch between an open state or a clamp state, wherein a printing medium passes through a gap between the drum and the clamping component when the clamping component is switched to the open state, and the printing medium is clamped by the support surface of the drum and the clamping component when the clamping component is switched to the clamp state; and a resilient component disposed between the frame and the clamping component, the resilient component being adapted to move the clamping component relative to the frame along the longitudinal direction of the opening for pressing the clamping component on the support surface of the drum to clamp an end of the printing medium.
