Abstract:
A print head can suppress contamination due to ink at the time of being mounted on a printing apparatus and/or after being detached from the printing apparatus. For this purpose, a positioning pin longer than a needle is provided in a joint unit of the print head, and the joint unit includes a shutter which closes an opening on a supply side and an opening on a collection side when the print head is detached.
