As shown in fig. 1 to 5, the present application provides an image forming apparatus, which may be a thermal printer, a thermal transfer printer, a thermal inkjet printer, a laser printer, or the like. The image forming apparatus includes a printer body and a paper supply device 1, the paper supply device 1 being for placing a printing medium (e.g., paper), the paper supply device 1 being mounted to the printer body. When the image forming apparatus is in operation, a printing medium enters the printer body along the paper feeding device 1 to complete printing.
Specifically, as shown in fig. 2 and 4, the sheet feeding device 1 includes a case 11, a handle 12, a medium tray 13, and a first transmission member 14, the handle 12 being mounted to the case 11 and being rotatable with respect to the case 11; the medium tray 13 is arranged in the box body 11 and can move relative to the box body 11; one end of the first transmission piece 14 is connected with the medium tray 13, and the other end of the first transmission piece 14 is connected with the handle 12; when the handle 12 is rotated, the medium tray 13 is driven to move by the first transmission piece 14, so that the medium tray 13 is in a paper placing state; when the medium tray 13 is in the paper-placing state, the handle 12 is pulled to drive the paper supply device 1 to be separated from the printer body.
When the user sets the printing medium to the image forming apparatus, the paper feeding device 1 needs to be pulled out. In the process of drawing out the paper supply device 1, the handle 12 is rotated, the handle 12 drives the medium tray 13 to move through the first transmission piece 14, so that the medium tray 13 is in a paper placing state, and then the handle 12 is pulled to pull the paper supply device 1 out of the printer body, so that the printing medium is placed on the medium tray 13. In this embodiment, the medium tray 13 is first set in the paper feeding state, and then the paper feeding device 1 is pulled out of the printer body, so that the process of placing the printing medium is divided into consecutive forward and backward movements, and compared with the two actions of lowering the medium tray 13 to the paper feeding state and pulling out the paper feeding device 1, the two actions occur synchronously, and the problem that the printing medium on the medium tray 13 is scratched or the position of the printing medium is shifted is solved.
As shown in fig. 2 and 4, the medium tray 13 is provided with a free end 131 and a fixed end 132, the fixed end 132 is connected with the case 11, and the free end 131 can rotate around the fixed end 132; when the medium tray 13 is in the working state, the free end 131 is far away from the bottom wall of the box body 11 than the fixed end 132, so that the medium tray 13 is in the inclined state; when the medium tray 13 is in the paper-feeding state, the free end 131 and the fixed end 132 are in the same plane, and the medium tray 13 is in a horizontal state. In this embodiment, the fixed end 132 is rotatably connected to the box 11, so that the first transmission member 14 drives the free end 131 to rotate around the fixed end 132, so as to make the medium tray 13 in a horizontal state, so that the following paper feeding device 1 is pulled out of the printer body and a printing medium is placed on the medium tray 13. The medium tray 13 is pushed by an external force to make the free end 131 rotate around the fixed end 132, so that the medium tray 13 is in a tilted state, so that the medium tray 13 feeds the paper to the printer body.
