Description

  The present invention relates to a left and right ruler that can be used without any inconvenience whether the dominant hand is a right hand or a left hand for measuring the size of an object or drawing a line.

  A ruler for measuring the size of an object or drawing a line is provided with an elongated transparent ruler body that is applied to an object such as paper, and the measurement dimension is measured on the back surface along one long side of the ruler body. The scale line of the short line perpendicular to the long side to be represented is displayed over the length of a predetermined dimension by engraving or printing at a predetermined interval, for example, in millimeter units, and in the vicinity of the scale line, for example, in centimeter units, etc. Dimensional notation is performed by marking or printing at intervals.

  In this dimension number notation, when the long side on which the scale line is displayed is on the upper side, the leftmost scale line is attached with the reference position number 0, and the larger number is attached in order toward the right side. (For example, refer to Patent Document 1).

  The standard ruler dimension notation is a left-to-right numeric array, as described above, which is convenient for right-handed people to use. Therefore, a normal ruler is inconvenient for left-handed people to measure the length of an object. Even right-handed users are not convenient when measuring the length of an object from right to left.

On the other hand, rulers for left-handed use are also commercially available, but the range of users is limited. Therefore, a number may be added to the number array in the opposite direction to an ordinary ruler, but there is a drawback that the ruler size notation becomes complicated.
