Similarly, the first cover 200 may be turned to close one-half, one-third, one-fourth, or three-fourths of the paper feeding ports 100a, which is not illustrated herein.
When both the first cover 200 and the second cover 900 are rotated to the position to close the paper feed port 100a, a side of the first cover 200 away from the first rotation shaft 300 abuts against a side of the second cover 900 away from the second rotation shaft 110. It should be understood that when the first cover 200 and the second cover 900 are both in the position of closing the paper feed port 100a, the areas of closing the paper feed port 100a are complementary, for example, when the first cover 200 can only close one half of the paper feed port 100a, the second cover 900 can correspondingly close the remaining one half of the paper feed port 100a, and for example, when the first cover 200 can only close one quarter of the paper feed port 100a, the second cover 900 can correspondingly close the remaining three quarters of the paper feed port 100a.
It can be appreciated that, in the printer according to the technical solution of the present utility model, by providing the rotatable first cover 200 and second cover 900 on the machine body 100, the first cover 200 can be rotated to a position for closing part of the paper inlet 100a under the driving of the first torsion spring 800, and the second cover 900 can be rotated to a position for closing the other part of the paper inlet 100a under the driving of the second torsion spring 160, so that in the daily use process, the paper inlet 100a is closed based on the first cover 200 and the second cover 900, thereby being beneficial to preventing dust and flies from entering the interior of the machine body 100 from the paper inlet 100a, further ensuring that components inside the machine body 100 can stably operate, and improving the operational reliability of the printer.
The first rotating shaft 300 includes a first extending end 300a, the first extending end 300a is provided with a first gear 400, the second rotating shaft 110 includes a second extending end 110a opposite to the first extending end 300a, and the second extending end 110a is provided with a second gear 120; the printer further includes a first rack 600 and a second rack 140 connected, the first rack 600 being positioned at the bottom of the first gear 400 and engaged with the first gear 400, and the second rack 140 being positioned at the top of the second gear 120 and engaged with the second gear 120.
For ease of understanding, referring to fig. 3 and 4, in fig. 3, when the top of the first cover 200 is pressed downward by the printing paper, the first rotating shaft 300 and the first gear 400 rotate clockwise, at this time, under the action of the first gear 400, the first rack 600 moves leftwards, and further drives the second rack 140 to move leftwards, and the second gear 120 rotates anticlockwise under the action of the second rack 140, and further drives the second rotating shaft 110 and the second cover 900 to rotate anticlockwise to open the paper inlet 100a.
When the printing paper is pressed down against the second cover 900, the first cover 200 is also rotated to open the paper inlet 100a.
It can be understood that, by means of the transmission of the gear and the rack, when one of the first cover 200 and the second cover 900 is propped to rotate, the other is driven to rotate together and open the paper inlet 100a together, so that when a user puts printing paper into the machine body 100, the user does not need to deliberately prop the printing paper against the first cover 200 and the second cover 900 at the same time, and the paper inlet 100a can be completely opened.
Specifically, to reduce implementation difficulty of the product, the first gear 400 and the second gear 120 have the same structure and are both located at the same height of the machine body 100, the first rack 600 and the second rack 140 are spaced apart in the height direction of the machine body 100, and one end of the first rack 600 away from the first gear 400 is connected with one end of the second rack 140 away from the second gear 120 through the first transmission rod 170.
To improve the reliability of the transmission between the first cover 200 and the second cover 900, in some embodiments, the first rotating shaft 300 includes a third extending end 300b disposed opposite to the first extending end 300a, the third extending end 300b is provided with a third gear 500, the second rotating shaft 110 includes a fourth extending end 110b disposed opposite to the third extending end 300b, and the fourth extending end 110b is provided with a fourth gear 130; the printer further includes a third rack 700 and a fourth rack 150 that are driven, the third rack 700 being located at the bottom of the third gear 500 and engaged with the third gear 500, the fourth rack 150 being located at the top of the fourth gear 130 and engaged with the fourth gear 130.
Similarly, to reduce the implementation difficulty of the product, the third gear 500 and the fourth gear 130 have the same structure and are both located at the same height of the machine body 100, the third rack 700 and the fourth rack 150 are arranged at intervals in the height direction of the machine body 100, and one end of the third rack 700 away from the third gear 500 is connected with one end of the fourth rack 150 away from the fourth gear 130 through the second transmission rod 180.
In order to avoid abrasion and wear of the printing paper, in this embodiment, it is preferable that a side of the first cover 200 away from the first rotating shaft 300 is chamfered, and a side of the second cover 900 away from the second rotating shaft 110 is chamfered, because the printing paper is inevitably rubbed against edges of the first cover 200 and the second cover 900 during the process of placing the printing paper into the machine body 100.
The first cover 200 and the second cover 900 are both rotatably mounted on the top wall of the machine body 100, and when the first cover 200 is rotated to a position for closing the paper feed port 100a, a part of the top end surface of the first cover 200 is abutted against the opening peripheral edge of the paper feed port 100a, and when the second cover 900 is rotated to a position for closing the paper feed port 100a, a part of the top end surface of the second cover 900 is abutted against the opening peripheral edge of the paper feed port 100 a. It can be appreciated that, by this arrangement, gaps between the opening periphery of the paper inlet 100a and the first cover 200 and the second cover 900 can be avoided, and the dustproof effect of the product can be improved.
In addition, in order to prevent the user from being unable to observe the placement of the printing paper due to the first cover 200 and the second cover 900 being mounted at the paper inlet 100a, in the present embodiment, the materials of the first cover 200 and the second cover 900 are transparent materials.
In practice, the first cover 200 and the second cover 900 may be highly transparent glass or plastic, and are not particularly limited herein.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
