The paper guide 126 is configured to operate when the paper is discharged to a specific discharge unit 121 desired by the user. Thereafter, a plurality of drive gears 123 are engaged with the rollers 122 of each discharge unit 121 so as to be rotatable simultaneously. That is, when one drive gear 123 rotates, all gears engaged with the drive gear 123 rotate to drive the roller 122.

Thereafter, the one-side drive gear 123 is provided with a motor 124 is configured to rotate the drive gear 123 by the power transmission gear 124a of the motor. Thereafter, the motor 124 constitutes a power supply device 125 for driving the motor.

However, the sorter of the paper stacking device for sorting and discharging the discharge paper configured as described above has to install a separate motor therein and install a separate power supply device for driving the motor. There was an increasing problem.

SUMMARY OF THE INVENTION In order to solve the above problems, an object of the present invention is to provide a paper stacking device of an electrophotographic processor that can operate without using a separate driving device for a sorter.

Another object of the present invention is to provide a paper stacking device of an electrophotographic processor that can be operated using a drive unit of the main body.

It is another object of the present invention to provide a paper stacking device of an electrophotographic processor that can reduce manufacturing costs.

In order to achieve the above object, the present invention is the main body and the discharge roller is connected to the drive unit of the main body to discharge the paper on which the image is formed in place, the upper side of the main body in the discharge direction at the position desired by the user A sheet stacking device including a sorter provided with a plurality of discharge units provided at predetermined intervals, wherein a plurality of rollers for discharging paper are provided on one side of each discharge unit, and the rollers are disposed on one side of each roller. Drive rollers equipped with drive gears are rotated to engage each other to rotate, and a belt is installed to rotate by simultaneously winding the discharge roller gear of the discharge roller and the gears of each drive roller of the sorter.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing the present invention, when it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the gist of the present invention, the detailed description thereof will be omitted.

2 is a block diagram of a paper stacking apparatus according to an embodiment of the present invention.

As shown in FIG. 2, the paper stacking device according to the present invention comprises a printer body 10 and a sorter 20 having a plurality of discharge parts capable of classifying paper 12 conveyed from the printer body.

At the bottom of the printer body 10, a paper feed cassette 11 capable of stacking a plurality of sheets to form an image is mounted. Thereafter, a pickup roller 13 for conveying the sheet of the uppermost sheet of the plurality of sheets 12 loaded in the paper feed cassette 11 into the main body at the lower side of the main body 10 is configured in place. Thereafter, in place of the main body 10, a developing device 14 for forming an image on the paper 12 conveyed from the paper feeding cassette 11 is provided. Further, the main body is provided with a fixing unit (not shown) for fixing the toner image formed from the developing device in place. A discharge roller 15 for discharging the image fixed by the fixing unit is provided above the fixing unit. The discharge roller 15 is connected to the developing driving motor (not shown) of the main body 10 by a plurality of gear couplings to transmit power. In addition, the discharge roller gear 15a is installed in the discharge roller 15 so as to rotate together with the discharge roller 15.

Thereafter, a sorter 20 for discharging the paper 12 on which the image is formed by the discharge roller 15 of the main body 10 and transporting the sheet 12 to a desired position is installed on the upper side of the main body 10. One side portion of the sorter 20 is provided with a plurality of discharge portions 21 for loading the discharged paper 12 at regular intervals in the longitudinal direction. In addition, one side of each discharge unit 21 is provided to engage a plurality of rollers 22 for feeding the paper conveyed to each discharge unit. In addition, the paper guide 25 which acts as a solenoid (Solenoid) is provided on one side of the roller 22 of each discharge unit 21. The paper guide 25 is configured to operate when the paper is discharged to a specific discharge unit 21 desired by the user. Thereafter, the rollers 22 of the respective discharge units 21 are provided to engage the driving rollers 23 for driving the rollers. In addition, each drive roller 23 is provided with a drive gear 23a for receiving power. Thereafter, the belt 24 is wound around the discharge roller gear 15a of the discharge roller 15 and the drive gear 23a of each drive roller 23 of the sorter 20 at the same time. That is, it is configured to drive all the drive gears 23 of the sorter 20 by the rotation of the discharge roller 15. In addition, the belt 24 is installed as a timing belt for accurate power transmission.

In the paper stacking device 20 having the above configuration, the paper 12 loaded from the paper feed cassette 11 of the main body 10 is transferred by the pickup roller 13, and at the same time, the developing unit 14 is operated and the discharge roller 15 is driven. In addition, the belt 24 is driven by the discharge roller 15, and the belt 24 simultaneously rotates the drive roller 23 of the sorter 20 provided above the main body 10. That is, all of the driving units of the sorter 20 can be rotated at a time by the power transmission motor (not shown) of the developing device 14.

As described above, since the sheet stacking apparatus of the electrophotographic processor according to the embodiment of the present invention can implement the driving of the sorter by the driving unit of the main body at the same time, the manufacturing cost of the product can be reduced and downsized.
