First Claim
Patent Images

1. an imaging device, comprising:

  • Supply unit, described supply unit is carried the recording medium of carrying on it;

    Multiple image-generating units, described multiple image-generating units are set to can retract individually with respect to described supply unit, on the described recording medium that described image-generating unit carries on described supply unit, form image;

    First sensor, described first sensor is arranged on the upstream side of described supply unit, to detect the end of described recording medium;

    The second sensor, described the second sensor setting is in the downstream of described supply unit, to detect the described end of described recording medium;

    WithCPU, described CPU determines the generation of paperboard, when based on from described recording medium detected when described first sensor or described the second sensor the described end until stop carrying the time of described recording medium and the transporting velocity of described recording medium in the time that described paperboard occurs, described CPU calculates the position of the described end of the recording medium being blocked on described supply unit, and in the time that described CPU determines the generation of described paperboard, described CPU reports from image-generating unit corresponding to positions in described multiple image-generating units and the described end recording medium being blocked on described supply unit.
