A ruler for drawing up a drawing for drawing up a reduce scale and angle

摘要

The present invention forms a writing instrument holder for mounting writing instruments on one side of the ruler, and installs a shaft pin so as to draw a curve or circle of a diameter at a desired scale, so that the curve or circle at a desired scale as well as a straight line The purpose of the present invention is to provide a drawing creator with scale and angle drawing function that can be easily used by drawing. Drawing preparation combines the scale and angle drawing function of the present invention is configured for this purpose in the ruler is formed with a scale, it is coupled to the body of the rule to be movable in the longitudinal direction while one side of the transparent material marked with a reference scale Movable piece; An axis pin installed at a lower distance from the reference scale on one side of the movable piece to form a center of rotation; A writing instrument holder for supporting a writing instrument to which a writing instrument insertion hole penetrated up and down is formed on one side of the ruler; And an elastic support piece for elastically supporting the outer circumferential surface of the writing instrument, which is formed in a number of elastic deformation so as to form a circle inside the writing instrument insertion hole of the writing instrument holder.
