The force interlocks the movement of the front end of the paper locking member 61 pivoted, and the downward movement of the paper locking member 61 is interlocked, so that the paper locking portion 613 is perpendicular to the paper feed tray 30. To ShinIri to. In this state, the paper pressing assembly is lifted, the paper locking assembly is moved downward, the paper is locked, and it is convenient for the user to place the sheet.

The paper is placed on the paper feed tray 30, and the paper latching portion 613 of the paper latching assembly extends into the paper latching groove 31 perpendicular to the paper feed tray 30 to limit the advance of the sheet.

Referring to FIG. 4, after a sheet is placed on the sheet feeding tray 30, a sensor (not shown) is touched, the motor starts rotating in the forward direction, the transmission assembly disengages the drive gear 21, and the motor is driven. Is transmitted, the restraining force of the paper pressing assembly disappears, and the elastic member 55 uses the elastic potential energy to push the paper pressing tray 52 and move it downward, so that the lifting portion 543 of the arm 54 moves within the sliding groove 526. It slides and vibrates downward to push the paper up to the paper pressing wheel 56 to the upper side of the paper feed roller 41 to provide the positive force required for paper feed by the paper feed roller 41. At the same time, the connecting member 62 A circular arc motion is performed along the column 516, the front end pivotally connected to the paper pressing tray 52 of the connecting member 62 moves downward, and the rear end pivotally connected to the paper locking member 61 of the connecting member 62 is lifted up. Stop member 6 The interlocking movement upward, Kamigakaritome portion 613 is disengaged from the paper locking groove 31 of the paper feed tray 30, abolished the paper locking function, it can be passed through the sheet.

  After the paper feeding is completed, the motor is reversed, the paper pressing assembly is lifted, the state before the paper feeding is restored, and the paper locking portion 613 is restored to the position of the paper locking function.

As described above, according to the paper feeding system 100 of the present invention, due to the structure of the paper pressing assembly and the paper locking assembly, the transmission assembly uses the drive gear 21 to transmit the clockwise rotation of the gear shaft 53 and the arm 54. , The paper pressing tray 52 is pulled and lifted upward until it aligns with the lower surface of the paper pressing tray rack 521, overcoming the elastic potential energy of the elastic member 55, and the paper locking member 61 downward by the connecting member 62 The movement can be linked to realize the paper locking function, and the paper can be placed at rest. When paper is fed, the transmission assembly uses the drive gear 21 counterclockwise, disengages the gear shaft 53 and the arm 54, uses the elastic member 55, releases the elastic potential energy, and pushes down the paper pressing tray 52. Paper can be moved downward, and the upward movement of the paper latching member 61 can be interlocked by the connecting member 62 to eliminate the paper latching function and feed paper. Accordingly, the functions of paper pressing and paper locking are achieved by driving one motor, and the structure of the paper feeding system 100 of the present invention is simple and the manufacturing cost is low.

  The detailed description of the present invention according to the above embodiments does not limit the scope of the present invention. Even if a person familiar with the present technology makes changes or adjustments within the scope of the present invention, the important significance of the present invention is not lost and is included in the scope of the present invention.
