The ADF generally has a paper feed plate 4 and a paper discharge plate 5, the paper feed plate 4 is located above the paper discharge plate 5, the paper feed plate 4 is used for placing the manuscript to be processed, and the paper discharge plate 5 is used for holding the paper of the output processed manuscript. Two paper width-limiting members 41 are generally disposed on the paper feeding plate 4 and are slidably connected to the paper feeding plate 4 in the width direction, so as to limit the width of the original placed on the paper feeding plate 4, since the two paper width-limiting members 41 are disposed above the paper feeding plate 4, the operation of the user is easy. A limiting slot hole 42 is formed in the corresponding paper feeding plate 4 in an extending manner along the width direction corresponding to the moving range of each paper feeding width limiting piece 41, and the two paper feeding width limiting pieces 41 are respectively installed in the corresponding limiting slot holes 42 in a limiting manner.
As shown in fig. 1 to 4, the ADF paper position correcting mechanism in this embodiment includes a paper output width limiting component 1, a paper output length limiting component 2, and an adjusting component 3.
The paper-out width-limiting assembly 1 is arranged between the paper-feeding plate 4 and the paper-out plate 5 and comprises a first width-limiting piece 11 and a second width-limiting piece 12 which are arranged at two sides of a paper-out position; the first width limiting member 11 and the second width limiting member 12 in this embodiment are connected to the corresponding paper feeding width limiting member 41 above the paper feeding plate 4 through a link rod, and the link rod is placed in the corresponding limiting slot 42. Because the first width limiting piece 11 and the second width limiting piece 12 are arranged at different positions, a user hardly touches the first width limiting piece 11 and the second width limiting piece 12, and after the first width limiting piece 11 and the second width limiting piece 12 are connected with the corresponding paper feeding width limiting piece 41 above the paper feeding plate 4, the first width limiting piece 11 and the second width limiting piece 12 are synchronously driven to move when the user operates the two paper feeding width limiting pieces 41, namely, the synchronous adjustment of the paper discharging width limiting assembly 1 and the paper discharging length limiting assembly 2 is realized while the limiting widths of the two paper feeding width limiting pieces 41 are adjusted, and the convenience of operation is improved.
