Claims (1)

[Claims for Utility Model Registration] (1) A document conveying device that includes a device for exposing a document above the inside of the main body of an image forming apparatus, and has a conveying means that rotates in either forward or reverse directions on the top surface of the main body of the device. The document inserted from the document insertion section side of the document conveyance device is rotated in the forward direction to pass through the exposure position and exposed, and then transferred to the downstream side of the document conveyance direction of the device main body. A first image forming mode in which the document is discharged to the document insertion section side by a document guide member provided, and the document contained in the carrier sheet is conveyed together with the carrier sheet to the exposure position by normal rotation of the conveyance means. and a second image forming mode in which the original is reversely transported to the original insertion section side by reversing the transporting means after the exposure is completed. In the document moving type image forming apparatus, the document guide member has a guiding state in which the document from the document transport device is guided toward the document insertion section, and a guide release state in which the document is not guided toward the document insertion section. When the original guide member is in the guide state, the second
An original moving image forming apparatus characterized in that an image forming mode cannot be set. (2) A device for exposing a document to light is provided above the interior of the image forming apparatus main body, and a document conveying device having a conveying means that rotates in either forward or reverse directions is provided on the top surface of the device body, and the document conveying device After the original inserted from the original insertion section side is passed through the exposure position by normal rotation of the conveying means and exposed, the original is guided by the original guide member provided on the downstream side of the apparatus main body in the original conveying direction. A first image forming mode in which the document is discharged to the insertion section side, and the document housed in the carrier sheet is conveyed together with the carrier sheet to an exposure position by rotating the conveyance means in the normal direction, and exposed, and after the exposure is completed. In the document moving image forming apparatus, the document movable image forming apparatus is capable of selectively setting either a second image forming mode in which the document is reversely conveyed toward the document insertion section by reversing the conveying means. , the document guide member is configured to be in either a guide state in which the document from the document transport device is guided toward the document insertion section, or a guide release state in which the document is not guided toward the document insertion section. Further, the document movable image forming apparatus is characterized in that the second image forming mode is automatically set when the document guide member is brought into a guide release state.
