A display light emitting device that emits display light to display a guidance image on a combiner mounted on a helmet, comprising; a wireless communication portion configured to receive, from a communication device, guidance information including distance information indicative of a distance from a current location to a predetermined guidance point and direction information indicative of a direction of travel at the guidance point; and an image control module having: an image generating portion configured to generate a guidance image including a distance image indicative of the distance to the guidance point based on the distance information and a direction image indicative of the direction of travel at the guidance point based on the direction information; and an image emitting portion configured to emit display light to display the guidance image on the combiner, and configured to control operations of the image generating portion and the image emitting portion, wherein the image control module is configured to perform control so that, when a condition is satisfied that the distance indicated by the distance information is less than a predetermined first reference distance, the distance image and the direction image are generated by the image generating portion and display light to display the guidance image including the generated distance image and direction image on the combiner is emitted from the image emitting portion, and perform control so that from when a condition is satisfied that the distance indicated by the distance information is less than a second reference distance shorter than the first reference distance to when the guidance point is reached, the display of the distance image of the guidance image is stopped and display light to continue to display the direction image is emitted, wherein a fifth reference distance is set that is from the guidance point to a location further away from the guidance point than the location of the first reference distance, the fifth reference distance is set at a plurality of points every distance interval longer than the first reference distance, and the image control module is configured to perform control so that the guidance image including the distance image and the direction image is displayed for a set predetermined period of time when each fifth reference distance is reached and, after the predetermined period of time, a display condition before the guidance image including the distance image and the direction image is displayed returns. a wireless communication portion configured to receive, from a communication device, guidance information including distance information indicative of a distance from a current location to a predetermined guidance point and direction information indicative of a direction of travel at the guidance point; and an image control module having: an image generating portion configured to generate a guidance image including a distance image indicative of the distance to the guidance point based on the distance information and a direction image indicative of the direction of travel at the guidance point based on the direction information; and an image emitting portion configured to emit display light to display the guidance image on the combiner, and configured to control operations of the image generating portion and the image emitting portion, wherein the image control module is configured to perform control so that, when a condition is satisfied that the distance indicated by the distance information is less than a predetermined first reference distance, the distance image and the direction image are generated by the image generating portion and display light to display the guidance image including the generated distance image and direction image on the combiner is emitted from the image emitting portion, and perform control so that from when a condition is satisfied that the distance indicated by the distance information is less than a second reference distance shorter than the first reference distance to when the guidance point is reached, the display of the distance image of the guidance image is stopped and display light to continue to display the direction image is emitted, wherein a fifth reference distance is set that is from the guidance point to a location further away from the guidance point than the location of the first reference distance, the fifth reference distance is set at a plurality of points every distance interval longer than the first reference distance, and the image control module is configured to perform control so that the guidance image including the distance image and the direction image is displayed for a set predetermined period of time when each fifth reference distance is reached and, after the predetermined period of time, a display condition before the guidance image including the distance image and the direction image is displayed returns.
