Claims

[Scope of Claim for Utility Model Registration] A copying device that reads an original image by an image reading means and copies the image onto a sheet material by an image writing means based on the reading result, the original and the sheet material. The image reading means is provided with a straight document/sheet material conveyance path for simultaneously conveying the original documents and sheet materials while overlapping each other, and a pair of conveyance rollers for conveying the document and sheet materials along the document/sheet material conveyance path, disposed on the document conveyance side of the sheet material conveyance path; on the other hand, the image writing means is disposed on the sheet material conveyance side of the document/sheet material conveyance path; and one of the image reading means and the pair of conveyance rollers. An image reading unit including a roller and an image writing unit including the image writing means and the other roller of the pair of transport rollers can be separated from each other with the document/sheet material transport path as a boundary. copying equipment.
