Claims

[Claims for Utility Model Registration] 1. A rectangular transparent sheet portion that supports the surface to be read of a document, a sheet portion that supports the other side of the document and has approximately the same shape as the transparent sheet portion, and transportation of both sheet portions. In a document carrier sheet for an image forming apparatus, which is composed of a fixing part that connects leading edges in the direction and extends in the transport direction, the document carrier sheet is formed from a shallower to a deeper depth than the depth of the fixing part from the leading edge of the carrier sheet in the transport direction. A document carrier sheet for an image forming apparatus, the document carrier sheet having a through hole for allowing the image forming apparatus to detect the leading end in the conveying direction of a document held between both sheet parts. 2. A rectangular transparent sheet part that supports the surface to be read of the original, a sheet part that supports the other side of the original and has approximately the same shape as the transparent sheet part, and the leading edges of both sheet parts in the conveyance direction are joined together. The fixing part extends in the transport direction, and is formed from a shallower to deeper depth than the depth of the fixing part from the leading edge of the carrier sheet in the transport direction, and supports the leading edge in the transport direction of the original sandwiched between both sheet parts. A document carrier sheet for an image forming apparatus having a through hole for detection by the image forming apparatus, a conveying path and a conveying means for conveying the document to the document reading section, and installed in the conveying path upstream from the document reading section. A leading end timing switch, a transfer means capable of visualizing and transferring the read information from the document reading section, a registration roller capable of conveying the transfer paper to the transfer position of the transfer means, and the document carrier sheet described above are used. When the leading edge timing switch is turned on and then turned on depending on the sheet or document, the control means can command the registration roller to operate and adjust the timing for transfer. Forming device.
