Claims14
A monitoring apparatus, comprising:
- a discharge case configured to receive a liquid discharged from a nozzle, the discharge case having a storage space configured to store the liquid, wherein the discharge case is disposed in a free falling path of the liquid discharged from the nozzle, wherein the discharge case comprises a transparent plate disposed above the storage space, wherein the transparent plate includes a vertical straight line formed thereon, and wherein the vertical straight line is disposed along a side of the free falling path of the discharged liquid;
- and
- a photographing unit comprising a camera, wherein the camera is configured to photograph a level of the liquid stored in the storage space.
A printing apparatus, comprising:
- a nozzle configured to discharge a liquid in a first direction onto a substrate, wherein the nozzle is configured to move in a second direction along a surface of the substrate;
- a discharge case configured to receive the liquid discharged from the nozzle, the discharge case having a storage space configured to store the liquid, wherein the discharge case is disposed between the nozzle and the substrate in the first direction, wherein the discharge case comprises a transparent plate disposed above the storage space, wherein the transparent plate includes a vertical straight line formed thereon, and wherein the vertical straight line is disposed along a side of the free falling path of the discharged liquid;
- and
- a photographing unit adjacent to the discharge case, the photographing unit comprising a camera configured to photograph a level of the liquid stored in the storage space.
