Claims

[Claims for Utility Model Registration] In a copying machine having a first conveyance means for conveying a light source, a rotation means for rotating a photoreceptor, and a second conveyance means for conveying copy paper, the light source reaches an exposure position. a first detection means disposed at a predetermined position on the conveyance path until the photoconductor reaches a certain exposure position and detects the light source; a second detection means for detecting a fixed position of the photoreceptor; and a positional error between the light source and the photoreceptor at the time when the light source is transported toward the exposure position and detected by the first detection means. a third detection means for detecting the rotation means; an exposure position control device having means for driving and controlling the first conveying means according to an error caused by the copy sheet; a fourth detecting means arranged to detect a fixed position of the copy paper or the transfer drum; a fifth detection means for detecting a positional error between the copy paper or the transfer drum and the photoreceptor; and a fifth detection means for detecting a positional error between the copy paper or the transfer drum and the second transport means until the copy paper or the transfer drum reaches the transfer position. In order to achieve phase synchronization with the rotation means, the second
1. A copying machine comprising: a transfer position control device having means for driving and controlling a conveyance means;
