The present invention relates to a device for painting lanes, crosswalks, and letter signs capable of preventing a slip used for various purposes, i.e. painting not only lanes but also crosswalks, signs, and letters, and improves a working property by forming a lane and lanes having various forms at once; and a method for painting lanes using the same. More specifically, the device for painting lanes, crosswalks, and letter signs capable of preventing slip comprises: a paint spraying part which can also manually be operated by a worker; an attachment and detachment part which attaches and detaches the paint spraying part; and a paint spray operating part which operates an operating lever such that the paint can be sprayed through the paint spraying part when the paint spraying part is mounted on a main body. Accordingly, the paint spraying part may be fixated by the attachment and detachment part coupled to the main body to be used, or may be detached from the attachment and detachment part to also be used for painting crosswalks, letters, and signs, other than painting lanes, by separately controlling only the paint spraying part by a worker. In addition, when the paint spraying part is attached, a fixating force of the paint spraying part can be increased by a means of a supporting rod and a locking unit of the attachment and detachment part, and the fixing force of the paint spraying part can further be increased by a means of a paint spraying unit supporting part; thereby facilitating smooth lane painting work. Moreover, the operating lever of the paint spraying part for spraying paint can manually or automatically be operated such that a worker can manually or automatically control the operating lever of the paint spraying part.;COPYRIGHT KIPO 2016
