Title: Field curvature correcting method for scanning image forming lens in optical scanner
Inventor: ITABASHI AKIHISA
IPC: G02B26/10
Filed: 1991-05-20
Abstract: PURPOSE:To effectively correct and reduce the variation portion of a field curvature caused by a working error by placing one piece in plural pieces of lenses for constituting a scanning image forming lens by displacing it in the main scan corresponding direction from an arranged position by a design. CONSTITUTION:One piece in plural pieces of lenses 4, 5 for constituting a scanning image forming lens 7 is placed in the main scan corresponding direction from an arranged position by a design, and by adjusting its displacement amount, the correction is executed. In such a state, in the case the scanning image forming lens 7 is constituted of two pieces, it is desirable to displace the lens of the side to be scanned, from the arranged position by a design. When the lenses 4, 5 are moved in parallel in the main scan corresponding direction, an incident angle to the lenses 4, 5 of a deflection luminous flux in the face swept by the deflection luminous flux is shifted. Therefore, this displacement exerts an effect being similar to a rotation of the lens around the axis being in parallel to the sub-scan corresponding direction, by which a field curvature also generates a rotational variation. Accordingly, a variation portion from a design value of the field curvature caused by a working error of the scanning image forming lens 7 can be reduced effectively.
