Claims (1)

[Claims for Utility Model Registration] 1. In order to transport the transfer material at a fixed position to the transfer position of the recording medium on which the image is formed, a detection means is provided which is activated by the movement of the document scanning means, and this detection means The conveyance is controlled so that the leading edge of the transfer material and the leading edge of the image formation on the recording medium are aligned at the transfer position by the operation of the sensing means, and the sensing means operates the sensing means provided in the sensing means and the document scanning means. A transfer material leading edge position adjusting device for adjusting the positional relationship with the plate includes the above-mentioned detection means disposed on the movement path of the above-mentioned original scanning means, and the detection means being actuated when the above-mentioned original scanning means is moved so that the original scanning means the detection plate provided corresponding to the detection means;
an adjustment plate that is integrally provided with the detection plate and is movable along the movement path of the document scanning means;
an adjustment member rotatably coupled to move the adjustment plate; a holding member for holding the adjustment member in a fixed position; and the adjustment plate or the adjustment member and the holding member. A device for adjusting the leading edge position of a transfer material, characterized in that a fixing means for fixing the position is provided between the detection plate and the detection means, so that the positional relationship between the detection plate and the detection means can be freely adjusted. 2. The transfer material leading edge adjustment device according to claim 1, wherein the fixing means includes a high friction member interposed between the adjustment member and the holding member. 3. The transfer material leading edge adjustment device according to claim 1, wherein the fixing means includes a pressure contact member that is brought into pressure contact with the adjustment plate, and surfaces of both pressure contact portions are formed in a high friction state. 4. The transfer material leading edge adjusting device according to claim 3, wherein the pressure contact surface of the adjustment plate and the pressure contact member is formed in a shape such that the two engage with each other.
