Abstract: In an image-recording device, a cartridge has a first chamber and an outlet. A mount body includes a tank, first and second sensors. The tank has an inlet, and a second chamber. The liquid in the first chamber flows into the second chamber via the outlet and the inlet. The first sensor outputs a first signal when a level of the liquid in the second chamber is higher than a first position, and outputs a second signal when the level is lower than the first position. The second sensor outputs a third signal when the level is higher than a second position higher than the first position, and outputs the fourth signal when the level is lower than the second position. A controller controls a notification device to issue a notification if a condition based on the first and second signals is satisfied.

Abstract: A lens holder which supports a projection lens is screwed and fixed to a bracket which supports a spatial light modulator. A positioning pin configured to position the lens holder in a left-right direction with respect to the bracket is inserted into a long hole which is formed in the bracket and extends in a lamp front-rear direction. The screwing and fixing is performed in a state where the positioning pin is inserted into the long hole and is appropriately moved in the lamp front-rear direction, so that the lens holder is restricted from being displaced in a left-right direction with respect to the bracket, and it is possible to finely adjust a positional relationship between the projection lens and the spatial light modulator in the lamp front-rear direction.
