PROBLEM TO BE SOLVED: To provide a liquid consumption device which suppresses reflected light at a surface opposite to a detection section of a holder and can highly accurately correcting relative positional information between a liquid container and the detection section. ! SOLUTION: A printer 10 comprises: detection sections 90 with light emitting sections 92 and light receiving sections 94 disposed in a main scanning direction; ink cartridges IC disposed with prisms 170 having edge lines in a sub-scanning direction and bottom surfaces 170c opposite to the detection sections 90; holders 20 detachably mounted with the ink cartridges IC having opening portions 22 at positions opposite to the bottom surfaces 170c of the prisms 170 in bottom portions 21 disposed opposite to the detection sections 90; and a carriage motor 33 for relatively moving the holders 20 in the main scanning direction with respect to the detection sections 90. The bottom portions 21 of the holders 20 have inclined surfaces 21a incline |
