機構。[Scope of Claim for Utility Model Registration] A correction shaft provided with a correction knob at one end and a correction pinion at the other end, which is rotatably supported by the correction shaft, and has an inclined surface at the tip of the circumferential surface. A first protrusion provided with a plurality of first protrusions.
a rotor; a second protrusion that has an inclined surface that can engage with the inclined surface of the first protrusion and is higher in the radial direction than the first protrusion, and further rotatable about the correction shaft;
a second rotor that is loosely coupled to be movable in the axial direction, one end of which is engaged with the correction shaft, the other end of which is engaged with either the first rotor or the second rotor, and the second rotor is engaged with the correction shaft; a pressing member that presses two protrusions toward the base of the first protrusion; a plurality of protuberances having shallow groove guide portions that allow the first protrusion of the first rotor to slide in the axial direction; and a plurality of protrusions between the protrusions. A deep groove guide portion is provided on the inner circumferential surface of the second rotor, and a second protrusion of the second rotor is slidable in the axial direction. a positioning cylinder formed with an inclined surface that can ride on the lower surface and an inclined surface that guides and moves from the raised lower surface to another deep groove guide portion; a second return zero cam that is rotatably provided on the second hand shaft; It is pivotably supported near the second hand axis and correction axis,
