Title:
IMAGE ACQUISITION DEVICE, INSPECTION DEVICE, TABLET PRINTING DEVICE, AND IMAGE ACQUISITION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/198643
Kind Code:
A1
Abstract:
This image acquisition device comprises a conveyance mechanism, an epi-lighting unit (71), a transmitted illumination unit (72), and an imaging unit (73). The conveyance mechanism conveys a tablet (9) by moving a conveyance belt (12) while the tablet (9) is suctioned and held at a suction hole (14) provided on the conveyance belt (12). The epi-illumination unit (71) emits light toward the tablet (9) from the side of the conveyance belt (12) with the surface (12a) whereon the tablet (9) is held. The transmitted illumination unit (72) emits light toward the tablet (9) from the reverse surface (12b) of the conveyance belt (12). When the imaging unit (73) captures images, both the epi-illumination unit (71) and the transmitted illumination unit (72) emit light. This makes it possible to brightly illuminate both the portion of the tablet (9) which overlays the suction hole (14) when viewed from the imaging unit (73) and the portion which does not overlay the suction hole (14). Accordingly, the tablet (9) that is light-transmissive can be clearly imaged.
