Description
SUMMARY OF THE INVENTION
BACKGROUND OF THE INVENTION
[0006] According to one embodiment of the present
[0001] The present invention relates to a thermal print-
pivotable, and is configured to open and close the roll
a direction extending along an axis of the shaft (52), the platen roller engagement portion (63d) and a tangential line of a track obtained when the axis of the shaft (52) moves along with an opening operation of the cover (20) form an intersection angleθAB in a closing direction of the lock arm (61), and the intersection angle θAB satisfies a relation of 90°≤θAB≤110°. Wherein the platen roller engagement portion (63d) and a tangential line of a track obtained when a contact point between the shaft (52) and the platen roller engagement portion (63d) pivots in an unlocking direction of the lock arm (61) form an intersection angle θBC in the closing direction of the lock arm (61), and the intersection angle θBC satisfies a relation of 0°≤θBC ≤10°.
