To provide a road surface drawing device which can form a drawn image with a small number of components and move the drawn image with the small number of components, and provide a vehicle which can perform road surface drawing with the small number of components and move the drawn image in the road surface drawing with the small number of components.SOLUTION: A road surface drawing device 50F can be mounted on an automobile 1. The road surface drawing device 50F comprises: a light source 51F which emits light LF; a drawing lens 52F which has an incidence surface 54 on which the light LF is incident and an emission surface 55 from which the light LF is emitted; a drive unit 80 which rotates the drawing lens 52F around an axis extending in an optical axis direction of the drawing lens 52F; and a control unit 60 which drives the drive unit 80 at a prescribed timing. At least one of the incidence surface 54 and the emission surface 55 includes a drawing contribution region 53F that refracts the light LF such that a drawn image 70F showing a prescribed character with the light LF is projected onto a road surface.SELECTED DRAWING: Figure 4
【課題】 少ない部品点数で描画像を形成することが可能で、少ない部品点数で上記描画像を動かすことが可能な路面描画装置、及び少ない部品点数で路面描画を行うことが可能で、少ない部品点数で路面描画における描画像を動かすことが可能な車両を提供することを目的とする。【解決手段】 路面描画装置50Fは、自動車1に搭載可能である。この路面描画装置50Fは、光LFを出射する光源51Fと、光LFが入射する入射面54及び光LFが出射する出射面55を有する描画レンズ52Fと、描画レンズ52Fの光軸方向に延びる軸中心に描画レンズ52Fを回転させる駆動部80と、駆動部80を所定のタイミングで駆動させる制御部60と、を備える。入射面54及び出射面55の少なくとも一方は、光LFによる所定のキャラクターを示す描画像70Fが路面に投影されるように光LFを屈折させる描画寄与領域53Fを含む。【選択図】 図4
