A paper roll carrying device is equipped with movable-type paper clamping arms for clamping paper rolls with different widths. The paper roll carrying device includes two paper clamping arms and two supporting mechanisms. The supporting mechanisms are respectively installed on the corresponding paper clamping arms. Each supporting mechanism includes a first support member, a second support member and a third support member. The supporting mechanism is specially designed to have the take-out slant surfaces on the supporting members. The supporting mechanism can be used to support paper cores with different diameters. When the user intends to remove the paper roll, it is not necessary to release the paper clamping arms.

Paper roll carrying device

A thermosensitive printing device includes a print roller, a printhead module, a printhead pressure adjusting mechanism and a casing. The printhead pressure adjusting mechanism is supported by the casing. When a print medium is transferred through a region between the printhead module and the print roller, the print medium is printed by the printhead module. The printhead pressure adjusting mechanism is located over the printhead module and contacted with the printhead At least a portion of the printhead pressure adjusting mechanism is penetrated through the casing groove and movable within the casing groove according to a width of the print medium. The printhead pressure adjusting mechanism includes an adjusting knob and an identification pattern. When an adjusting knob is rotated, a pressure of the printhead pressure adjusting mechanism applied to the printhead module is adjusted and the pressure is recognized according to the identification pattern.
