[0039] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application. EMBODIMENT

[0040] As Figures 1 to 9 shown, a paper dispenser of an upper paper feeding type printer includes a machine body 1, a paper bin 2, a push rod 3 and a linear drive device.

[0041] The machine body 1 includes an upper shell and a lower shell, which are connected by screws. The front side and the right side of the upper shell and the lower shell are provided with notches, so as to enclose an opening on the front side and an insertion opening on the right side. The insertion opening is aligned with a Type-C interface 1.1 module on a control circuit board 8, for external power supply and transmission of control signals.

[0042] The paper bin 2 is installed in the front side of the machine body 1 in a plug-in manner and is provided with a slope surface 2.1 for bearing photo paper. The slope surface 2.1 has an inclination angle of 40-50°, so as to facilitate the photo paper to slide to the paper feeding opening of the printer.

[0043] The push rod 3 is mounted on the body 1, and since the body 1 is a shell type component, the push rod 3 is at least partially arranged in the body 1, and its front end can extend out of the opening on the front side of the body 1. The push rod 3 functions to provide a pushing force to the photo paper placed in the paper bin 2, so as to move the photo paper up along the slope 2.1, and realize the switching of the paper type. As a preferred example, the part of the push rod 3 in contact with the photo paper is provided with anti-skid lines, so as to increase the friction, and push the photo paper to move up.

[0044] The linear driving device is mounted in the body 1 to drive the push rod 3 to reciprocate forward and backward.

[0045] As a preferred example, the linear driving device comprises a sliding block 5, a rotating disc 6 and a motor 4. The sliding block 5 is mounted in the body 1 to slide along a straight line, and is provided with a sliding groove 5.1. The sliding groove 5.1 is arranged perpendicularly to the moving direction of the sliding block 5. The motor 4 is mounted in the body 1, and is electrically connected with the control circuit board 8. The rotating disc 6 is coaxially mounted on the main shaft of the motor 4, and is provided with an eccentric shaft 6.1. The eccentric shaft 6.1 is movably arranged in the sliding groove 5.1. When the motor 4 rotates, the eccentric shaft 6.1 on the rotating disc 6 rotates around the shaft, and drives the sliding block 5 to reciprocate along a straight line. The movement of the sliding block 5 finally drives the push rod 3 to move.

[0046] As a preferred example, in order to more smoothly drive the sliding block 5 to move, the linear driving device further comprises a first roller 7, which is mounted on the eccentric shaft 6.1 and forms a rolling fit with the side wall of the sliding groove 5.1. By changing the sliding fit into a rolling fit, the friction during the fit can be reduced, so that the mechanism moves more smoothly.

[0047] As a preferred example, the paper dispenser further comprises a front detector 9 and a rear detector 10, which are arranged in the body 1 in front of and behind each other, and are electrically connected with the control circuit board 8. The sliding block 5 is provided with a detection block 5.2, which can pass through the front detector 9 and the rear detector 10 during the linear movement of the sliding block 5 to trigger the generation of signals. When the sliding block 5 moves to the detection block 5.2 passing through the front detector 9, the front detector 9 generates a signal to the control circuit board 8, and the control motor 4 stops, at this time, the sliding block 5 moves to the most front end. Similarly, when the sliding block 5 moves to the detection block 5.2 passing through the rear detector 10, the rear detector 10 generates a signal to the control circuit board 8, and the control motor 4 stops, at this time, the sliding block 5 moves to the most rear end. As a preferred example, the front detector 9 and the rear detector 10 are light sensing switches, and the light path is blocked by the detection block 5.2 to generate a signal.

[0048] As a preferred example, the slope 2.1 of the paper bin 2 is provided with a second roller 11. The second roller 11 is provided with a plurality of rollers, which form a rolling contact with the photo paper, so that when the push rod 3 pushes the photo paper, the photo paper is better moved up, and the excessive friction between the photo paper and the slope 2.1 is prevented, so that the photo paper cannot be normally moved up.

[0049] As a preferred example, the paper dispenser further comprises a first paper sensor 13 and a second paper sensor 14, the first paper sensor 13 is arranged on the front side of the body 1 and located on the right side of the paper tray 2; the second paper sensor 14 is arranged on the slope surface 2.1 of the paper tray 2. The first paper sensor 13 and the second paper sensor 14 are both electrically connected with the control circuit board 8. The first paper sensor 13 is used to detect whether the paper in the paper inlet of the printer is insufficient, and the second paper sensor 14 is used to detect whether the paper in the paper tray 2 is insufficient.

[0050] As a preferred example, the paper dispenser further comprises an elastic component, the elastic component connects the sliding block 5 and the push rod 3 so that the push rod 3 provides a downward pressure. This design can make the push rod 3 provide enough pushing force to move upward after contacting the photo paper 100. The elastic component is a torsion spring installed on the pin shaft of the sliding block 5 and the push rod 3, or an elastic sheet fixed at one end on the sliding block 5 and abutting against the push rod 3 at the other end.

[0051] Working process and principle of embodiment 1

[0052] As shown in Figure 8 and 9 , taking A4 paper 200 and 6-inch photo paper 100 as examples, the paper dispenser in the present application is placed above the paper inlet of the printer and aligned with the paper inlet position of the photo paper. A plurality of A4 paper 200 is placed in the paper inlet of the printer, and a plurality of 6-inch photo paper 100 is placed in the paper tray 2. The A4 paper 200 is located below the 6-inch photo paper 100. As shown in Figure 8 , the push rod 3 is in the default position, i.e., the last end. At this time, the 6-inch photo paper 100 is on the slope surface 2.1 and extends into the paper inlet of the printer, and the printer starts the printing task of the 6-inch photo paper 100. As shown in Figure 9 , when it is necessary to switch to A4 paper 200, the paper dispenser is started to move the push rod 3 forward to the front end, and the push rod 3 pushes the 6-inch photo paper 100 upward to leave the paper inlet of the printer. At this time, the printer starts the printing task of the A4 paper 200. Through the device, automatic switching of two types of paper can be realized, and the user experience is improved. Embodiment

[0053] As shown in Figure 10As shown, compared with the embodiment 1, the difference of the embodiment lies in that, in the embodiment, the linear driving device comprises a sliding block 5, a screw rod motor 15 and a nut. The sliding block 5 is linearly slidingly installed in the machine body 1, and the sliding block 5 is hingedly connected with the push rod 3. The screw rod motor 15 is installed in the machine body 1, and the screw rod of the screw rod motor 15 is parallel to the movement direction of the sliding block 5. The nut 16 is fixed on the sliding block 5 and is threadedly connected with the screw rod of the screw rod motor 15. The screw rod motor 15 is electrically connected with the control circuit board 8, and after the operation of the screw rod motor 15, the sliding block 5 can be driven to move forward and backward.
