PURPOSE:To facilitate reading, by a method wherein a reading device for a recording paper for a multipen recorder consists of a transparent plate having rectangular holes whose sides are equal to the displacement width of the pen point and the longitudinal width of the recording paper. CONSTITUTION:In a reading device for a recording paper for a recorder having, for example, 4 pens, rectangular holes 6a and 6b, having a width being equal to a displacement distance of pen points and a length being equal to the width of the recording paper, are formed in transparent base board 5, and a distance between the holes 6a and 6b is also equalized to the displacement distance (a) of the pen point. Graduations, corresponding to the graduations in the direction of the width of the recording paper, are marked along the holes 6a and 6b. This facilitates readings of the recording paper. |
