A printer includes: a carriage that includes a recording head and is configured to move in a width direction intersecting a medium transport direction; a liquid storage unit that stores an ink supplied to the recording head, is mounted on the carriage, includes a filling port configured such that the ink is filled therethrough, and is formed of a light-transmissive material; a visual recognition unit that is provided in the liquid storage unit and is configured to visually recognize a position of a liquid level in the liquid storage unit; an illumination unit that emits a light beam; and a light guide unit that guides the light beam emitted from the illumination unit such that the light beam is applied to the visual recognition unit from a rear side, when the visual recognition unit faces a front side.

Electric apparatus and control method therefor

An apparatus for controlling movement of a target object generates a first operation quantity for first feedback control, and determines a second operation quantity for second feedback control in accordance with which of plural regions obtained by dividing a two-dimensional space defined by two variables of the first and second state quantities includes the first and second state quantities. The plural regions include first, second and third regions, the first region being provided between the second and third regions. The second operation quantity is determined so that the second operation quantity when the first and second state quantities are located in the first region is less than the second operation quantity when the first and second state quantities are located in the second region or the third region.

SLIDING MECHANISM AND INK-JET PRINTER
20200262222 · 2020-08-20 · ·

A sliding mechanism is provided and includes a linear encoder for detecting a movement distance of a slider in relation to a support member. The sliding mechanism includes a slider that can move in relation to a support member, a slider that can move in relation to the support member as well as the slider, a linear scale fixed to the slider and a sensor fixed to the slider; and a linear encoder for detecting a movement distance of the slider in relation to the support member. In the sliding mechanism, the slider is transferred in relation to the support member and the slider, and subsequently the slider is transferred in relation to the support member and the slider, while the slider is kept in a state of being stopped.

Liquid discharge apparatus

There is provided a liquid discharge apparatus including: a liquid discharge head having a nozzle surface; a carriage; a carriage mover; a conveyor conveying a medium in a conveyance direction; a velocity sensor; a distance sensor; and a controller. The controller makes a determination regarding the velocity of the carriage based on output of the velocity sensor, and makes a determination regarding the distance between the medium and the nozzle surface based on output of the distance sensor. In a case that that the controller determines that the velocity is less than a predetermined velocity and that the distance is less than a predetermined distance, the controller interrupts recording performed by the liquid discharge head.
