When the carbon ribbon box is installed on the printer, the printer is firstly contacted with the protection part 8, so that the direct scraping and damage of the carbon ribbon X in the installation process and other printers can be avoided, and a good protection effect is achieved on the carbon ribbon X.
Preferably, the protecting rib 81 is in a strip shape, and the surface facing the carbon ribbon X is a plane, so that the protecting rib 81 is prevented from scratching and damaging the carbon ribbon X. The protection ribs 81 on the two sides are not connected, so that the installation of the carbon ribbon X is facilitated. One end of the protective rib 81 is fixedly connected to the side wall of the shell 1, and the other end is a movable end, so that the carbon ribbon X can conveniently enter between the protective rib 81 and the substrate 82. More preferably, the two sides of the substrate 82 are provided with second through holes, and the protection ribs 81 are correspondingly arranged above the second through holes.
In the embodiment, a limiting spring arm 64 is disposed on a side wall of the housing 1, so as to press the supply reel 3 against the accommodating cavity 63. Preferably, the stop spring arms 64 are provided on a side wall perpendicular to the axis of the supply reel 3. The stopper spring arm 64 is divided into a first arm portion 641, a second arm portion 642 and a third arm portion 643 in this order from the fixed end, and the third arm portion 643 is bent in the vertical direction with respect to the second arm portion 642. The second arm 642 protrudes toward the supply spool 3 with respect to the third arm 643 to form a stepped portion for restricting the supply spool 3 within the accommodation chamber 63. Preferably, the second arm 642 is inclined with respect to the horizontal plane, and can gradually push the stopper spring arm 64 to deform and be assembled into the housing chamber 63 when the supply reel 3 is mounted.
In the embodiment, the third arm 643 is located at the side of the end face of the supply spool 3 to restrict the movement of the supply spool 3 in its own axial direction. The position of the carbon ribbon X on the supply reel 3 is stable, and the carbon ribbon X can be smoothly supplied, and the carbon ribbon X is prevented from jumping back and forth on the supply reel 3. Be equipped with the draw-in groove in the mounting groove 72, be equipped with the chuck on collecting spool 4, chuck and draw-in groove cooperation restriction are collected spool 4 and are in its own axial pivoted removal, avoid collecting spool 4 to make carbon ribbon X steadily collect, and then carbon ribbon X steadily supplies and collect, help improving printing quality.
And C, installing a carbon ribbon X: the housing 1 is set with its back face upward, and the supply reel 3 around which the carbon tape X is wound is mounted in the housing chamber 63. Then the carbon ribbon X is pulled to pass through the carbon ribbon guiding part 9 and is led to the protecting part 8; the housing 1 is turned over and the carbon ribbon X is passed between the base plate 82 and the ribs 81, and then wound onto the take-up reel 4. By providing the housing cavity 63 with an opening facing the back and providing the mounting groove 72 with an opening facing the front face, the mounting device has the advantage of convenience in mounting.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, and various modifications and variations may be made to the present invention by those skilled in the art.
