Container having liquid detecting function, and sensor unit
摘要:
A mis-assembly preventing structure is provided to a liquid container to allow assembly of parts when the parts are assembled in an adequate direction and to prevent the assembly of the parts when the part are assembled in an inadequate direction. For example the structure can be provided to a sensor unit (200) and a cartridge case (101), and can be constructed by engagement hooks (267) and engagement concave portions (110k) for receiving the engagement hooks (267).
