There is provided a liquid discharge head, including: a pressure chamber connected to a nozzle from which a liquid is discharged; an actuator configured to apply discharge pressure to the liquid in the pressure chamber; a first supply channel which is connected to the pressure chamber, and through which a first liquid is supplied to the pressure chamber; a second supply channel, different from the first channel, which is connected to the pressure chamber, and through which a second liquid different from the first liquid is supplied to the pressure chamber; a first valve which is disposed in the first supply channel, and by which the first supply channel is opened and closed; and a second valve which is disposed in the second supply channel, and by which the second supply channel is opened and closed.

Liquid discharge head

There is provided a liquid discharge head, including: a plurality of inlet parts provided corresponding to a plurality of kinds of liquids; a plurality of pressure chambers in which discharge pressure is applied to the liquids; a plurality of individual outlet parts through which the liquids are supplied to the plurality of pressure chambers; and a manifold which communicates with the plurality of inlet parts, and through which the liquids from the plurality of inlet parts are supplied to the plurality of individual outlet parts. The manifold includes: a plurality of upstream-side portions in each of which a channel corresponding to one of the plurality of inlet parts is defined, and a downstream-side portion which communicates with the plurality of upstream-side portions, and in which a channel communicating with the plurality of individual outlet parts is defined.

A HMD photographs at least a portion of a field of view of a user, and detects a hand of the user based on a result of analysis of an imaged image. The HMD performs a control of deciding and displaying a position of an operation part of a virtual operation panel based on a position of the detected hand of the user. A position associated with the hand visible to the user is set as a display position of the virtual operation panel which tracks the position of the hand of the user. The HMD determines whether or not the virtual operation panel is operated based on a contact position of a finger of the user detected by a touch panel, and performs a control corresponding to an operation position of the virtual operation panel when it is determined that the virtual operation panel is operated.

Head mount display

A HMD images at least a portion of a field of view of a user, and detects a user's hand based on a result of an analysis of an imaged image. The HMD performs a control of defining and displaying a position of an operation part of a virtual operation panel based on a position of the detected user's hand. A position associated with the hand observed by the user is set as a display position of the virtual operation panel which tracks the position of the user's hand. The HMD detects an operation conducted by a user's finger, determines whether or not the virtual operation panel is operated based on the operation conducted by the detected finger, and performs a control corresponding to an operation position of the virtual operation panel when it is determined that the virtual operation panel is operated.
