The first gear set includes a sixth gear 71, a first gear 72, a second gear 73, a swing plate 74, and a compression spring 732. The sixth gear is connected to the driving gear 61. The first gear 72 is rotatably mounted in the housing 1 via a first support shaft 721 and meshes with the second gear 73. The second gear 73 is rotatably mounted in the housing 1 via a second support shaft 731 and meshes with the first gear 72. The second support shaft 731 is swayably mounted in the housing 1. One end of the swing plate 74 is movably connected to the first support shaft 721, and the other end is connected to the second support shaft 731. The compression spring 732 is sleeved on the second support shaft 731 and always forces the second gear 73 to move closer to the swing plate 74. The compression spring 732 causes the second gear 73 to press tightly against the swing plate, generating a rotational friction torque, which can drive the swing plate 74 to rotate at a certain angle.

[0054] In this embodiment, the second gear set is the seventh gear 75, which is connected to the input gear 51 in a transmission manner.

[0055] Combination Figure 4 , Figure 5 and Figure 6 As shown, the switching drive mechanism can drive the print head 21 or the scanning head 3 away from the rubber roller 5; in this embodiment, the power input end of the switching drive mechanism can engage and disengage with the first gear set to achieve transmission; specifically, the switching drive mechanism in this embodiment includes a third gear 82, a fourth gear 83 and a fifth gear 84, the third gear 82 can mesh with the second gear 73 for transmission; the fourth gear 83 rotates coaxially with the third gear 82; the fifth gear 84 meshes with the fourth gear 83 for transmission and has a cam 85 that rotates coaxially, the cam 85 can act on the print head 21 or the scanning head 3 to drive the print head 21 and the scanning head 3 away from the rubber roller 5.

[0056] There are two fourth gears 83 that rotate synchronously through a connecting shaft 81. Correspondingly, there are also two fifth gears 84 that are respectively sleeved on both ends of the rubber roller support shaft 52.

[0057] Combination Figures 4-6 As shown, the housing 1 is provided with a mounting support plate 14 and a mounting plate 15 at intervals. The rubber roller 5 and the connecting shaft 81 are respectively rotatably mounted on the mounting support plate 14 and the mounting plate 15.

A scanning bracket 31 is rotatably provided inside the housing 1 via a shaft pin 32, and the scanning head 3 is disposed on the scanning bracket 31. The second reset member 34 is disposed between the inner wall of the housing 1 and the outer end face of the scanning head 3.

[0061] In this embodiment, both the first reset member 23 and the second reset member 34 are tower-shaped springs.

[0062] Working principle:

[0063] The motor rotates counterclockwise, causing the drive gear to rotate, which in turn drives the sixth gear and the first gear to rotate. This causes the swing plate to swing counterclockwise and be limited, enabling the second gear 73 to mesh and drive the seventh gear to rotate counterclockwise. This, in turn, causes the input gear of the rubber roller to rotate clockwise, and the rubber roller to rotate, thus enabling the traction of printed or scanned documents.

[0064] The motor rotates clockwise, and the motor gear transmission drives the drive gear to rotate, which in turn drives the sixth gear and the first gear to rotate. This causes the swing plate to swing clockwise and be limited, enabling the second gear 73 to mesh with the third gear, which in turn drives the fourth gear to rotate. The fourth gear drives the fifth gear and simultaneously drives the cam 85 to rotate. The cam 85 pushes and lifts the print head or scanning head away from the rubber roller. When the print head is lifted away, the scanning head contacts and clamps the rubber roller to perform scanning. When the scanning head is lifted away, the print head comes closer to the rubber roller to perform printing.
