Claims

[Claims for Utility Model Registration] A drawing board having a stepped portion formed at the lower part, and on which a large number of latitude scales are written at predetermined pitches at least a predetermined distance from the upper and lower ends, and for the stepped portion, A slide plate that is movably attached flush with the drawing board and has at least a latitude line opposite to the latitude line scale written on it, a side end surface of the drawing board, a side end surface and a lower end surface of the slide board. It is attached movably in the vertical direction of the drawing board, the vertical direction of the slide board, and the left and right directions with respect to a guide member fixed to the guide member, and the difference between the predetermined pitch and the predetermined distance from the ends of the drawing board and the slide board. A swinging member having a shaft fixed at a position separated by a predetermined width and swinging around the shaft; and a swinging member that is attached to and detached from the swinging member with the drawn portion aligned with the axis of the shaft. 1. A drawing board for creating a perspective drawing, comprising a straightedge that can be attached, and a scale for drawing a perspective drawing by drawing radial lines using the straightedge that swings about the axis.
