Document Type and Number:
Japanese Patent JP6731237
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To solve such a problem that it is difficult to exactly recognize the state of a glue stored in a glue box because a range capable of visual observation of an inner part of the glue box is narrow and the inner part of the glue box is dark, and it is difficult to recognize a liquid surface height of the glue because the glue stored in the glue box is attached onto the wall surface of the inside of the glue box up to a slightly upper part than the liquid surface.SOLUTION: An optical source is provided on a control device, a front window and a side window are provided on a glue box, an optical axis of the light source is directed such that light applied from the optical source is made incident to an inner part of the glue box from the side window of the glue box and is emitted to an outer part of the glue box from the front window of the glue box, thereby, the inner part of the glue box is brightened, direct visual observation of cross-section of the glue is permitted and the state of the glue is easily recognized. Further, a boundary of brightness and darkness of light is displayed on a position of liquid surface height of the cross section of the glue projected on the front window and the liquid surface height of the glue is easily recognized.SELECTED DRAWING: Figure 1
