Beschreibung
Zusammenfassung:	A mold monitoring apparatus for an injection molding machine captures an image of a cavity portion of an opened mold, and determines the state of the cavity portion by means of image processing. The apparatus includes a light emitting unit, an image capturing unit, and an image processing unit. The light emitting unit projects onto the cavity portion light rays other than visible light rays. The image capturing unit includes an image sensor for capturing reflection light rays that travel from the cavity portion to the image sensor via a filter for blocking visible light rays. The image processing unit determines the state of the cavity portion on the basis of an image signal output from the image sensor and through image processing.
