[0018] Refer to Figures 1 to 4, the thermal printer includes a base 11, a cover 12, a rubber roller 111, a thermal sheet 124, and an ambient light assembly 2. The base 11 is provided with a paper bin 112. The cover 12 is hinged to the base 11 and covers the paper bin 112. An outlet 13 is formed between the cover 12 and the base 11. The rubber roller 111 is rotatably arranged on the base 11. The thermal sheet 124 is arranged on the cover 12. The thermal sheet 124 and the rubber roller 111 face each other and form a paper feeding channel, which communicates between the outlet 13 and the paper bin 112.
[0019] The cross-sectional profiles of the cover 12 and the base 11 are arranged in a rectangle. The cover 12 includes a bottom cover 123 and an outer cover 120. The thermal sheet 124 is arranged at the bottom side of the bottom cover 123. The bottom cover 123 is provided with a mounting position on the outer periphery above the thermal sheet 124. The ambient light assembly 2 includes a light-transmitting bracket 21 and a light bar 22. The light-transmitting bracket 21 extends in a U shape. The light-transmitting bracket 21 is arranged above the outlet 13 and is fixedly assembled to the mounting position. The light-transmitting bracket 21 is located at the outer contour of the bottom cover 123. The light-transmitting bracket 21 is made of a light-transmitting material, such as materials like PC, PMMA, PS, etc. The outer end of the light-transmitting bracket 21 is provided with a U-shaped light-transmitting surface 211. The U-shaped light-transmitting surface 211 includes a bottom surface 2111 and side surfaces 2112 located on both sides of the bottom surface 2111. The bottom surface 2111 is located at the end of the cover 12 in the length direction. The two side surfaces 2112 are respectively located at the ends of the cover 12 in the width direction.
[0020] The upper end of the U-shaped light-transmitting surface 211 is provided with a reflection inclined surface 212. The light-transmitting bracket 21 is provided with an assembly groove 214 on the inner side of the reflection inclined surface 212. Both the reflection inclined surface 212 and the assembly groove 214 extend in a U shape. The assembly groove 214 has a mounting opening at the upper part. The cross-section of the assembly groove 214 is arranged in a rectangle. The inner wall of the assembly groove 214 and the reflection inclined surface 212 are arranged at an acute angle. A reflection film 216 is plated on the outer side of the reflection inclined surface 212. The ambient light assembly 2 further includes a light-shielding strip 215. The light-shielding strip 215 extends in a U shape and covers the mounting opening.
[0021] The light bar 22 can adopt an LED light-emitting mode. The light bar 22 extends in a U shape and is arranged in the assembly groove 214. The light bar 22 emits ambient light towards the reflection inclined surface 212. The color and mode of the ambient light can be adjusted according to the needs such as the state of the printer and the application scenario. The ambient light enters the U-shaped light-transmitting surface 211 after being reflected by the reflection inclined surface 212 and the reflection film 216.
[0022] The outer cover 120 is provided with a U-shaped notch 121. The outer cover 120 is covered on the top of the bottom cover 123. The U-shaped light-transmitting surface 211 is located at the U-shaped notch 121. The outer cover 120 is provided with a mating inclined surface 124 on the inner side of the U-shaped notch. The mating inclined surface 124 is located on the outer side of the reflecting inclined surface 212 and faces the reflecting inclined surface 212. The light-transmitting bracket 21 is provided with a positioning step 213 on the outer side of the reflecting inclined surface 212. The edge 122 of the U-shaped notch is located at the positioning step 213 and is adjacent to the positioning step 213.
[0023] Of course, the above-mentioned atmosphere lamp assembly 2 can also be applied to another model or type of thermal printer. For example, the thermal sheet is arranged on the base, and the rubber roller is rotatably arranged on the cover body. Applying the atmosphere lamp assembly of this case to such printers can also achieve the invention purpose of this case.
[0024] As can be seen from the above, by the light-transmitting bracket and the light bar both extending in a U shape, and then after being installed in the U-shaped extending assembly groove, using the reflection of the reflecting inclined surface, the atmosphere light is incident on the U-shaped light-transmitting surface after reflection. Not only is the distribution of the atmosphere light uniform, but it extends in a U shape and is located at the ends in the width direction and the length direction, so that the state of the printer can be observed from multiple angles and understood in time. Furthermore, through the arrangement of the reflection film and the light-shielding strip, the refraction and distribution of the atmosphere light are more concentrated and uniform, and by the relative position of the mating inclined surface and the reflecting inclined surface, and the edge of the U-shaped notch being located at the mating of the positioning step, the installation opening of the outer cover better fits the assembly of the light-transmitting bracket.
