Patent number: 11618321Abstract: A panel device includes a panel unit, a light-blocking layer, and an indicator light projector. The light-blocking layer is located between the panel unit and the indicator light projector, specifically, on a rear surface of the panel unit. The indicator light projector is located relatively close to the light-blocking layer. When indicators displayed on the panel unit are viewed from the outer side, representations provided by the indicator light projector are visually recognizable even when viewed from an angled position.Type: GrantFiled: July 29, 2021Date of Patent: April 4, 2023Assignee: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventors: Yusuke Nomura, Akito Ishihara, Yuki Sakai
