Abstract: A liquid ejecting apparatus includes a liquid ejecting unit, a carriage, an optical machine, a liquid receiving unit, and a suction mechanism. The liquid ejecting unit is designed to form an image by ejecting a droplet from a nozzle formed in a nozzle forming surface to a medium. The carriage holds the liquid ejecting unit. The optical machine is held by the carriage. The liquid receiving unit is designed to receive a liquid discharged from the liquid ejecting unit in a discharge operation for maintenance of the liquid ejecting unit. The suction mechanism has a surface provided with a suction opening that allows ambient air on a liquid ejecting unit side to be sucked therefrom during the discharge operation.

Abstract: An inertial sensor device includes a first interface, a second sensor, a second interface, a host interface, and a processing circuit. The first interface is an interface for a first sensor configured to detect a first physical quantity in a first detection axis, a second physical quantity in a second detection axis, and a third physical quantity in a third detection axis. The second sensor is configured to detect the physical quantity in the third detection axis as a high-accuracy third physical quantity with a higher accuracy than the first sensor. The processing circuit is configured to output the first physical quantity and the second physical quantity to a host via the host interface, and output the high-accuracy third physical quantity instead of the third physical quantity to the host via the host interface.

Abstract: A fluid ejecting apparatus includes a nozzle that ejects fluid; a transporting section that transports in a direction of transportation a medium on which the fluid lands; and a mist sucking section that sucks air including a mist portion when the nozzle ejects the fluid, so as to move the mist portion from a route that extends from the nozzle to the spot on the medium where the fluid lands. The mist portion is a portion of mist, which is part of the fluid ejected by the nozzle that does not land on the medium and is floating.
