Description

Technical Field

[0001] The present invention relates to the field of printing technology, and particularly to a printing and scanning all-in-one machine. Background Art

[0002] With the continuous development of the economy, the demand for printing and scanning all-in-one machines is increasing. Traditional printing and scanning all-in-one machines can complete printing and scanning tasks. However, in traditional printing and scanning all-in-one machines, the paper feeding paths for printing and scanning are independent, resulting in a relatively large volume and high cost of the printing and scanning all-in-one machine. Summary of the Invention

[0003] Based on this, the objective of the present invention is to provide a printing and scanning all-in-one machine with a relatively small volume and reduced cost.

[0004] A printing and scanning all-in-one machine includes a machine housing, a paper feed tray, a paper pickup board, a paper pickup roller, a paper support board, a printing paper feed roller, a printing device, a partition layer, a scanning paper feed roller, a scanning device, and a scanning switching door; the interior of the machine housing is divided into an upper printing space and a lower scanning space by the partition layer;

[0005] The printing space is provided with the printing paper feed roller and the printing device, and the printing paper feed roller is used to convey paper to the printing device;

[0006] The scanning space is provided with the scanning paper feed roller and the scanning device, and the scanning paper feed roller is used to convey paper to the scanning device;

[0007] An inlet is formed on one side wall of the upper part of the machine housing, and the paper feed tray is inclinedly arranged below the outside of the inlet. A paper pickup space is formed inside the machine housing and below the inlet. The paper support board is arranged at the lower part of the paper pickup space. A paper pickup board and a paper pickup roller facing each other are arranged above the paper support board inside the paper pickup space. A paper rubbing space is formed between the paper pickup board and the paper pickup roller, and the paper pickup roller is used to convey paper to the printing paper feed roller or the scanning paper feed roller;

[0008] The partition layer is provided with a scanning paper inlet, which is located between the paper support board and the printing paper feed roller and is close to the paper support board. The scanning switching door is hinged on the scanning paper inlet to open or close the scanning paper inlet. The scanning switching door is driven by a driving mechanism to drive the scanning switching door to rotate in the vertical direction.

[0009] In the present invention, the paper is obliquely extended into the casing from the paper feed port, and is located between the paper pick-up paper board and the paper pick-up wheel, and its lower end abuts against the upper part of the paper support paper board. When the scanning switching door is closed, the paper slides over the upper part of the scanning switching door under the action of the paper pick-up wheel, and enters the printing paper feed roller to be printed on the paper by the printing device; when the scanning switching door is opened, the paper passes through the scanning paper feed port under the action of the paper pick-up wheel and enters the scanning paper feed roller to be scanned by the scanning device; the present application can allow the printing device and the scanning device to share a paper pick-up path through the setting of the scanning switching door, thereby making the structure of the printing and scanning all-in-one machine less, reducing the volume of the printing and scanning all-in-one machine, and reducing the production cost of the printing and scanning all-in-one machine.

[0010] Preferably, the area of ​​the paper support close to the scanning switching door is inclined downward toward the scanning switching door to form an inclined guiding surface, so that the paper can enter the scanning paper feeding roller through the scanning paper inlet when the scanning switching door is opened.

[0011] Preferably, the upper portion of the scanning switching door is tilted in an arc shape in a direction away from the paper support, so that when the scanning switching door is closed, the paper enters the upper portion of the scanning switching door through the guide surface and then tilts up and enters the printing paper feeding roller.

[0012] Preferably, a side of the scanning paper feed port facing the paper support plate is provided with an inclined surface for facilitating the paper to enter from the scanning switching door to the printing paper feed roller.

[0013] Preferably, an arc-shaped rib is provided on the upper portion of the scanning switching gate, and the arc-shaped rib extends from an end of the upper portion of the scanning switching gate close to the paper support plate to an end of the upper portion of the scanning switching gate away from the paper support plate.

[0014] Preferably, a plurality of the arc-shaped ribs are evenly arranged on the upper portion of the scanning switching gate along the length direction.

[0015] Compared with the prior art, the printing device and the scanning device in the printer-scanner all-in-one machine of the present invention share a paper picking path, which can reduce the number of parts in the housing, thereby reducing production costs, and also reducing the size of the printer-scanner all-in-one machine, achieving miniaturization.

[0025] As Figures 1 to 4 shown, the present invention relates to a printing and scanning all-in-one machine, including a housing 1, a paper feed tray 2, a paper pickup board 3, a paper pickup wheel 4, a paper support board 5, a printing paper feed roller 6, a printing device 7, a partition layer 8, a scanning paper feed roller 9, a scanning device 10, and a scanning switching door 11; the interior of the housing 1 is divided by the partition layer 8 into a printing space 12 in the upper part and a scanning space 13 in the lower part;

[0026] The printing space 12 is provided with the printing paper feed roller 6 and the printing device 7, and the printing paper feed roller 6 is used to convey the paper to the printing device 7;

[0027] The scanning space 13 is provided with the scanning paper feed roller 9 and the scanning device 10, and the scanning paper feed roller 9 is used to convey the paper to the scanning device 10;

[0028] On one side wall of the upper part of the casing 1, a paper inlet 14 is provided. Below the lower part outside the paper inlet 14, the paper feed tray 2 is inclinedly arranged. Inside the casing 1 and below the paper inlet 14, a paper picking space 15 is formed. Below the paper picking space 15, the paper support plate 5 is provided. Inside the paper picking space 15 and above the paper support plate 5, a paper picking board 3 and a paper picking wheel 4 are arranged opposite to each other. A paper rubbing space is formed between the paper picking board 3 and the paper picking wheel 4. The paper picking wheel 4 is used to convey the paper to the printing paper feeding roller 6 or the scanning paper feeding roller 9;

[0029] On the partition layer 8, a scanning paper inlet 18 is provided. The scanning paper inlet 18 is located between the paper support plate 5 and the printing paper feeding roller 6, and the scanning paper inlet 18 is close to the paper support plate 5. On the scanning paper inlet 18, the scanning switching door 11 is hinged to open or close the scanning paper inlet 18. The scanning switching door 11 is driven by a driving mechanism to drive the scanning switching door 11 to rotate in the vertical direction.

[0030] In the present invention, the paper obliquely extends into the casing 1 from the paper inlet 14. It is located between the paper picking board 3 and the paper picking wheel 4, and its lower end abuts against the upper part of the paper support plate 5. When the scanning switching door 11 is closed, the paper slides over the upper part of the scanning switching door 11 under the action of the paper picking wheel 4 and enters the printing paper feeding roller 6 to print the paper through the printing device 7; when the scanning switching door 11 is opened, the paper enters the scanning paper feeding roller 9 through the scanning paper inlet 18 under the action of the paper picking wheel 4. The scanning paper feeding roller 9 continues to feed the paper and enters the scanning space 13 to scan the paper through the scanning device 10; through the setting of the scanning switching door 11 in this application, the printing device 7 and the scanning device 10 can share a paper picking path, and further, the structure of the printing and scanning integrated machine can be less, the volume of the printing and scanning integrated machine can be reduced, and the production cost of the printing and scanning integrated machine can also be reduced.

[0031] The area of the paper support plate 5 close to the scanning switching door 11 is inclined downward toward the scanning switching door 11 to form an inclined guiding surface 16, so as to facilitate the paper to enter the scanning paper feeding roller 9 through the scanning paper inlet 18 when the scanning switching door 11 is opened.

[0032] Through the setting of the guiding surface 16, when the scanning switching door 11 is opened, the paper slides downward under the guidance of the guiding surface 16, which can ensure that the paper can smoothly pass through the scanning paper inlet 18 and enter the scanning paper feeding roller 9 in the scanning space 13.

[0033] Preferably, the upper part of the scanning switching door 11 is arched upward along the direction away from the paper support plate 5, so that when the scanning switching door 11 is closed, the paper enters the upper part of the scanning switching door 11 through the guiding surface 16, then arches upward and enters the printing paper feeding roller 6.

[0034] The upper part of the scanning switching gate 11 is tilted in an arc shape, so that when the scanning switching gate 11 is closed, the paper can descend under the action of the guide surface 16, and then tilt upward when passing through the scanning switching gate 11, so that the paper can pass through the scanning switching gate 11 and enter the printing paper feeding roller 6, ensuring that the paper enters the printing device 7 smoothly.

[0035] Furthermore, a side of the scanning paper feed port 18 facing the paper support plate 5 is provided with an inclined surface 17 for facilitating the paper to enter from the scanning switching door 11 to the printing paper feed roller 6 .

[0036] By setting the inclined surface 17 , when the paper slides over the upper part of the scanning switching door 11 , the paper can be guided to enter the printing paper feeding roller 6 better.

[0037] In this embodiment, an arc rib is provided on the upper portion of the scanning switching gate 11 , and the arc rib extends from an end of the upper portion of the scanning switching gate 11 close to the paper support 5 to an end of the upper portion of the scanning switching gate 11 away from the paper support 5 .

[0038] The arc ribs are provided to reduce the friction between the paper and the upper part of the scanning switching gate 11, so that the paper can slide over the arc ribs and enter the printing paper feed roller 6. At the same time, the arc ribs are provided to improve the structural strength of the scanning switching gate 11 and enhance its service life.

[0039] Preferably, a plurality of arc-shaped ribs are evenly arranged on the upper portion of the scanning switching door 11 along the length direction, so as to further enhance the structural strength of the scanning switching door 11 and facilitate the sliding of the paper.

[0040] In summary, compared with the prior art, the printing device 7 and the scanning device 10 in the printer-scanner all-in-one machine of the present invention share a paper feeding path, which can reduce the number of components in the housing 1 and thus reduce production costs, while also reducing the size of the printer-scanner all-in-one machine and achieving miniaturization.

[0041] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the invention patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
