Abstract
The present invention provides a working machine that makes it possible to alert its operator to cautions properly without obstructing the view of the operator. The working machine includes a cab for its operator to ride in, a projection device that projects image light to form an image of cautions to an operator who operates the working machine, a display unit that displays image light projected by the projection device, state detection element to detect a state of the working machine, and a controller that controls the projection device so that a manner of displaying the cautions on the display unit will change depending on the state of the working machine detected by the state detection element.
Claims3
A working machine provided with a cab for its operator to ride in, comprising:
- a projection device that projects image light to form an image of cautions to an operator who operates the working machine;
- a combiner that displays image light projected by the projection device;
- a controller that controls the projection device;
- and
- a gate lock lever that allows the operator to switch between a locked state in which operation of the working machine is disabled and an unlocked state in which operation of the working machine is enabled;
- wherein in a case where the gate lock lever is in the unlocked state, the controller displays the cautions on the combiner in a second display manner in which the cautions are more likely not to obstruct the view of the operator than in a first display manner of displaying the cautions in a case where the gate lock lever is in the locked state.
Dependencies are inferred from the claim text.
