Printer

Abstract

The utility model discloses a printer which comprises a printer body, a first paper feeding roller set, a second paper feeding roller set and a clutch piece. The first driving piece provides power for rotation of the first paper feeding roller set, through the clutch piece, the first driving piece can convey paper in the paper feeding channel and the page turning channel at the same time, only the first driving piece can convey the paper in the paper feeding channel, the number of the driving pieces is reduced, and meanwhile the paper feeding efficiency is improved. And in order to avoid the problem that the paper in the page turning channel interferes with the paper printed in the paper feeding channel when entering the paper feeding channel again, a material basis of the transmission structure is provided, and the length of the page turning channel is allowed to be shorter, so that the size of the printer is effectively controlled.

Claims

1. A printer, characterized in that: include A machine body (1) is provided with a paper feeding channel (11), a page turning channel (12) and a paper output channel (13); the paper output end of the paper feeding channel (11) is connected to the paper feeding end of the paper output channel (13), the paper feeding end of the page turning channel (12) is connected to the paper feeding end of the paper output channel (13), and the paper output end of the page turning channel (12) is connected to the paper feeding end of the paper output channel (13); A first paper feeding roller group (2), which is mounted on the machine body (1) and is suitable for conveying paper in the paper feeding channel (11); A second paper feeding roller group (3), which is mounted on the machine body (1) and is suitable for conveying the paper in the page turning channel (12); A clutch member (4) is mounted on the machine body (1) and is suitable for engaging or disengaging the first paper feed roller group (2) and the second paper feed roller group (3) so as to achieve a transmission connection or a disconnection between the first paper feed roller group (2) and the second paper feed roller group (3); A first driving member (6) provides power for the rotation of the first paper feeding roller group (2).

2. A printer as claimed in claim 1, characterized in that: It also comprises a print head (5) and a controller, wherein the print head (5) is suitable for printing the paper in the paper feeding channel (11); the controller is suitable for controlling the clutch member (4) to disconnect the first paper feeding roller group (2) from the second paper feeding roller group (3) when the print head (5) is printing the paper and the paper in the page turning channel (12) reaches a predetermined position.

3. A printer as claimed in claim 2, characterized in that: It also comprises a sensor, which is suitable for sending a first signal when the paper reaches a predetermined position, and the controller is suitable for receiving the first signal and controlling the clutch member (4) to disconnect the first paper feed roller group (2) from the second paper feed roller group (3).

4. A printer as claimed in claim 2 or 3, characterized in that: The controller is suitable for controlling the clutch component (4) to achieve transmission connection between the first paper feed roller group (2) and the second paper feed roller group (3) when the printing of the print head (5) is completed.

5. A printer as claimed in claim 1, characterized in that: The second paper feeding roller group (3) comprises a correction roller (31), a first transmission roller (32), and a second transmission roller (33); the clutch member (4) is suitable for engaging with or disengaging from the correction roller (31); the correction roller (31) is transmission-connected to the first transmission roller (32); the second transmission roller (33) is directly opposite to the first transmission roller (32) so as to be rotated in the opposite direction relative to the first transmission roller (32) by the action of the first transmission roller (32) so as to transport the paper in the page turning channel (12).

6. A printer as claimed in claim 5, characterized in that: The correction roller (31) and the first transmission roller (32) are driven by gears or belts (34).

7. A printer as claimed in claim 6, characterized in that: The number of the first transmission rollers (32) is at least two, and the number of the second transmission rollers (33) is the same as that of the first transmission rollers (32) and corresponds one to one.

8. A printer as claimed in claim 1, characterized in that: The printer further comprises a second driving member (8) and a third paper feed roller group (7), wherein the second driving member (8) is adapted to drive the third paper feed roller group (7) so that the third paper feed roller group (7) transports the paper in the paper output channel (13) out of the printer, or transports the paper in the paper output channel (13) to the page turning channel (12).

9. A printer as claimed in claim 1, characterized in that: The clutch member (4) is connected to the first paper feed roller group (2) or the second paper feed roller group (3) in a transmission manner, and is suitable for engaging with or disengaging from the other of the first paper feed roller group (2) or the second paper feed roller group (3) so as to connect the first paper feed roller group (2) with the second paper feed roller group (3) in a transmission manner or disconnect the connection manner.

10. A printer as claimed in claim 1, characterized in that: The clutch member (4) comprises two mutually transmitting matching parts, and the two matching parts are respectively suitable for engaging with or disengaging from the first paper feeding roller group (2) and the second paper feeding roller group (3).
