Description

Paper sorting apparatus of printer

The present invention relates to a paper sorting apparatus of a printer, and more particularly, to a paper sorting apparatus of a printer for sorting and removing printed sheets by moving the catch roller left and right with an actuator according to a user's selection.

In general, a printer is an apparatus for forming an image on paper according to print data sent from a computer. When a user performs a desired operation such as a document operation on a computer and sends a print content to the printer, desired characters or figures are printed. The paper is discharged to the output tray to obtain the desired printed matter.

However, such a typical printer may need to sort and load paper, for example, when printing a large number of multiple documents or when a network printer uses multiple printers at the same time. Since paper is mixed with each other, there is a problem in that users need to sort them one by one.

In order to solve this problem, a separate paper sort loader has been developed and sold separately as an option. However, in order to use such a paper sorting loader, a device must be purchased separately from the printer and installed outside the printer, thus occupying a lot of installation area and having a high purchase cost.

The present invention has been made to solve the above problems, by changing the axial position of the catch roller to the left and right according to the printing command so that the paper is discharged to another position on the output tray, do not install a separate paper sorting loader. It is an object of the present invention to provide a paper sorting apparatus of a printer capable of classifying and discharging printed sheets using only a device embedded in the printer.

In order to achieve the above object, the paper sorting apparatus of the printer according to the present invention includes a catch roller for discharging the printed paper with a discharge tray while rotating and moving left and right with respect to the backup roller, and one end of which is slid to the frame of the printer. And a slide guide which supports the catch roller so as to rotate and simultaneously guides the catch roller to move left and right, and an actuator connected to the other end of the slide guide to move the slide guide from side to side. It is done.

Here, the actuator is preferably a solenoid, it is preferable that a spring for returning the slide guide is interposed in the movable portion of the solenoid.

In addition, one end of the slide guide is characterized in that the sensor for detecting the left and right movement of the slide guide is installed, the sensor is preferably a photosensor.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of a paper sorting apparatus of a printer according to the present invention.

1 and 2, the paper sorting apparatus according to the present invention includes a catch roller 10, a slide guide 20, an actuator 30, and a sensor 40.

The catch roller 10 discharges the printed paper by interlocking with the backup roller 13 to the discharge tray. The catch roller shaft 11 moves to the left and right with respect to the backup roller 13 by the actuator 30. Installed on the

The slide guide 20 is installed in parallel with the catch roller 10, one end of which is connected to the movable part 31 of the actuator, and the other end of the slide guide 20 is slidably supported by the printer frame 7. In addition, one side of the slide guide 20 is formed with a plurality of support portions 21 for supporting the catch roller 10 in rotation. Therefore, when the slide guide 20 is moved left and right, the catch roller 10 is also moved left and right as well.

As the actuator 30 moves the slide guide 20 to the left and right, any actuator for implementing a linear reciprocating motion may be used, but preferably, a solenoid is used. This embodiment relates to the use of a solenoid as the actuator 30.

The movable part 31 of the solenoid is connected to one end of the slide guide 20, and a spring 33 is interposed between the end of the movable part 31 and the body of the solenoid 30. The spring 33 causes the solenoid movable portion 31 to move to the right by the elastic force of the spring 33 when the solenoid 30 is turned off so that the catch roller 10 returns to the R1 position. The spring 33 preferably uses a compressed cone coil spring having a large elastic force relative to the volume.

The sensor 40 is for checking the position of the catch roller 10 and is installed at a position capable of detecting the other end of the slide guide 20. When the sensor 40 is ON, the solenoid 30 does not operate and the catch roller 10 is in the R1 position. When the sensor 40 is OFF, the solenoid 30 operates to catch the roller 10. ) Is set to the R2 position. The sensor 40 may be used as long as it can detect the stage of the slide guide 20, but preferably uses a photosensor.

Hereinafter, the operation of the paper classification apparatus of the printer according to the present invention configured as described above will be described with reference to FIGS. 1 to 3.

When power is first applied to the printer, the solenoid 30 is set not to operate, and the catch roller 10 is assumed to be at the R1 position.

First, when the printed paper is discharged to the intermediate position P0, when the catch roller 10 rotates while the solenoid 30 does not operate, the printed paper 1 is discharged to the P0 position.

Next, a case where the printed paper 1 is discharged to the P1 position will be described.

When the solenoid 30 is OFF, that is, the catch roller 10 is in the R1 position with the sensor 40 ON, the leading edge of the printed paper 1 is the catch roller 10. When the predetermined length is entered into the solenoid 30 is turned on (ON). When the solenoid 30 is ON, the connected slide guide 20 moves toward the solenoid 30 and the catch roller 10 connected to the slide guide 20 moves to the R2 position. At this time, since the other end of the slide guide 20 moves away from the sensor 40, the sensor 40 is turned off.

When the catch roller 10 moves to the R2 position, the paper 1 passing between the catch roller 10 and the backup roller 13 is moved toward the solenoid 30 by the friction force of the catch roller 13, and the discharge tray 5 ) Is discharged to the P1 position.

The printed paper 1 is discharged to the P2 position of the discharge tray 5 as follows.

In order to discharge the paper 1 to the P2 position, the catch roller 10 must first be located at the R2 position. Therefore, when the discharge command at the P2 position is received, it is checked whether the sensor 40 is in an OFF state. If the sensor 40 is in an ON state, the catch roller 10 is in the R1 position, and the solenoid 30 is operated to allow the sensor 40 to be in an OFF state.

Subsequently, when the leading edge of the printed paper between the catch roller 10 and the backup roller 13 at the R2 position enters a predetermined length, the solenoid 30 is turned OFF to slide the guide 20 by the elastic force of the spring 33. To the right to allow the catch roller 10 to move to the R1 position.

When the catch roller 10 slides on the backup roller 13 while the paper is interposed, the paper is also moved toward the sensor 40 on the backup roller 13 by the frictional force of the catch roller 10, and the discharge tray 5 ) Is discharged to the P2 position.

Therefore, the paper sorting apparatus according to the present invention can classify the printed paper 1 into three places P0, P1, and P2 above the discharge tray and discharge the paper.

That is, when a printer having a paper classification apparatus according to the present invention is used by connecting to a network, it is possible to classify the output position by outputting differently for each user and classify it with the prints of other users.

As described above, according to the paper sorting apparatus of the printer according to the present invention, since the catch roller is moved left and right by using a solenoid to sort and discharge the paper, the apparatus built in the printer without installing a separate paper sorting stacker. Only the printed paper can be sorted and discharged.

The present invention is not limited to the above-described specific embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Of course, such changes will fall within the scope of the claims.
