Title:
LIGHT RADIATION UNIT, PRINTING DEVICE, AND PRINTING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/181551
Kind Code:
A1
Abstract:
This light radiation unit (30) has a housing (31), a light source (32), a light-focusing lens (33), and a light-transmissive member (34). An opening (312) is formed in a bottom surface (311) of the housing (31). The light source (32) and the light-focusing lens (33) are disposed within the housing (31). The light-transmissive member (34) is disposed at the opening (312) of the housing (31). The light-focusing lens (33) focuses the light emitted from the light source (32). The light-transmissive member (34) transmits the light focused by the light-focusing lens (33). The light-transmissive member (34) has a flat bottom surface. Thereby, it is possible to prevent air flow disturbance due to the light-focusing lens (33) from arising between the light radiation unit (30) and a printing medium (9).
