Abstract
Official abstract text for this publication.
Visibility of information that is provided to a worker is enhanced. A working machine includes an indicator device that functions as an information providing unit that provides information of a machine body to the worker, and the indicator device emits an indicator light to a ground that is located in front of the working machine and is exposed to a worker side that is located at a manipulation position.
First claim
Opening claim text (preview).
What is claimed is: 1. A working machine including an illumination device and an information providing unit, said illumination device and said information providing unit being disposed between an operator and a front of said working machine, said illumination device being disposed so as to illuminate an area ahead of the working machine and said information providing unit providing information to the operator, wherein the information providing unit includes an indicator device that emits an indicator light indicating the information, an emitting direction of the indicator light deviating from an optical axis of an illuminating light of the illumination device; wherein the indicator device is disposed on the illumination device and emits the indicator light to a region outside of the area ahead of the working machine that is illuminated by the illumination device, wherein the region is located between a front of the working machine and the area illuminated by the illumination device, and wherein the front of the working machine blocks the light from the illumination device so as to form a shadow in said region to which the indicator light is emitted. 2. The working machine according to claim 1 , wherein the indicator light is a light indicating at least any one of images including a color, flashing, and a character. 3. A working machine including an illumination device and an information providing unit, said illumination device illuminating an area ahead of the working machine and said information providing unit providing information to a worker, wherein an emitting direction of the indicator light deviates from an optical axis of an illuminating light of the illumination device; wherein the information providing unit includes an indicator device that emits an indicator light indicating the information, the indicator device emitting the indicator light to a surface of a front portion of the working machine that is exposed to a worker side. 4. The working machine according to claim 3 , wherein the indicator light is a light indicating at least any one of images including a color, flashing, and a character. 5. The working machine according to claim 3 , wherein the indicator device is disposed on the illumination device.
