AI Technical Summary
Technical Problem
The risk of ink leakage from a refillable tank in printers leading to adhesion on viewing walls due to the exposed supply port location, which is accessible from the outside.
Method used
A liquid supply device with a tank design that includes a first wall allowing visibility, a supply port, and a cover with a film protruding beyond the wall to form grooves for guiding leaked ink away from the viewing area, utilizing capillary action to prevent adhesion.
Benefits of technology
Effectively reduces ink adhesion to the viewing wall by guiding leaked ink into grooves, ensuring minimal exposure and easy cleanup.

Abstract
To reduce adhesion of liquid to a viewing wall for checking the remaining amount of liquid stored in a tank. [Solution] The multifunction device (10) comprises an ink tank (100) having a standing wall (102) through which ink stored in an ink chamber (111) can be seen from the outside, and a supply port (112) provided above the standing wall (102) for supplying liquid to the ink chamber (111); a standing wall (76) having an opening (81) formed therein, the standing walls (102, 76) facing each other, and a binding member (120) covering the standing wall (102) in a state in which the central portion of the standing wall (102) is visible from the outside through the opening (81); a film (142) attached to the ink tank (100) in a state in which it protrudes from the edge of the standing wall (102) toward the binding member (120); and a positioning portion that positions the ink tank (100) relative to the binding member (120) in a state in which the distance between the portion of the film (142) attached to the ink tank (100) and the binding member (120) is length G. The length (length L) of the film (142) protruding from the standing wall (102) is longer than length G.
