DETAILED DESCRIPTION OF THE INVENTION

BACKGROUND OF THE INVENTION The present invention relates to a plurality of printers
And a printer system including the stacker .

2. Description of the Related Art FIG. 3 shows a printer system for printing on cut paper.
1 shows a schematic configuration of a stem. In FIG. 3, reference numeral 1 denotes a hopper. The paper 2 stacked on the hopper 1 is sent out of the hopper 1 by the pick mechanism 3, and is passed through the paper transport mechanism so that the toner image formed on the photosensitive drum 4 and the paper 2 coincide with each other in the transfer device 5 . Sent to the cabin. On the other hand, the toner image is formed through the following steps.
First, the surface of the photosensitive drum 4 is uniformly charged by the charger 6. Next, the modulated laser light emitted from the optical unit 7 scans the photosensitive drum 4. Each time the laser beam scans on the photosensitive drum 4, the charge on the portion of the photosensitive drum 4 irradiated with the laser beam disappears, and an electrostatic latent image is formed. The photosensitive drum 4 rotates at a constant speed,
After passing through the developing device 8, the toner is sucked into the electrostatic latent image portion and is developed as a toner image. This toner image is suctioned and transferred to the sheet 2 by the transfer device 5. The transferred paper 2 is separated from the photosensitive drum 4 by the peeling device 9 and sent to the fixing device. Fixing unit is backup roll 10
The paper 2 is pressed and heated by these two rolls, and the toner image is fixed on the paper 2. The sheet 2 on which the toner image has been fixed is discharged to the stacker 14 or the stacker 15 based on the selection of the direction of the switching lever 12. The stackers move down the tables 141 and 151 as the sheets 2 are stacked, and when the stacking amount of the sheets 2 reaches the specified value, the table 1
41 and 151 reach the positions of the sensors 142 and 152, and the switching lever 1
2. Change the direction of 2 and switch the paper
Sends it to the stacker that guides you.

[INVENTION point problem to be solved In a conventional sample tray such as in the form <br/> printer system without a dedicated tray to verify the output of, there is an output result to be required to confirm the operator immediately However, since it could not be taken out during printing, the stacker had to temporarily store a specified amount of paper and had to wait until the specified amount was reached. Also, after the paper has reached the specified amount, the amount of paper taken out increases, so it takes time to align the paper, and because the amount of paper increases, it becomes heavy, making it difficult to handle paper The problem had arisen. SUMMARY OF THE INVENTION It is an object of the present invention to provide a printer system which can take out an output result even when the number of sheets in an arbitrary stacking amount is desired without stopping the printing state even if the number of sheets in the stacker has not reached a predetermined amount .

SUMMARY OF THE INVENTION The object of the present invention is to provide a printer.
Is installed at the latter stage of the printer and ejected from the printer.
A plurality of stackers for storing the stacked sheets,
The plurality of paper feeders are provided on a paper transport path connecting each stacker.
Of the stackers, the stacker used as the paper
Printer system with a selection lever to select
And provided so as to be able to be pulled out with respect to the main body of the stacker.
Is, the hand holding it heavy loading the discharged paper from the printer
Table and the table are pulled out of the stacker body.
Open switch for moving in the direction
To move in the direction to store in the stacker body
Switch and the open switch and closed switch
Switches at the same time, the switch lever
To change the stacker used as the paper output destination
Means.

By adopting the above configuration, even if the number of sheets in the stacker does not reach the specified amount, it is possible to take out the output result at an arbitrary accumulation amount without stopping the printing state.

Embodiments of the present invention will be described below with reference to the drawings.
You. Figure 1 is a control flowchart of the present invention, the two stackers 14 and 15 to start printing by selecting the stacker 14, illustrates the case of switching the sheet discharge to the stacker 15 by the operation of printing in the switch I have. The stacker is provided with a panel switch as shown in FIG.
Ri, pressing the open switch 16 when the printing is stopped, issues an automatic table lowering the table in the stacker forward, is operated to retrieve the printed paper. When the close switch 17 is pressed while printing is stopped, the table enters the stacker main body and raises the table to the sheet stacking position. Also,
When printing, open switch 16 or black
Even if you press the over's switch 17 alone it becomes invalid. When printing, the open switch 16 and the
When the rose switch 17 is pressed at the same time, the control device (FIG.
Command ( not shown) to switch the stacker,
In response to this, a stacker switching instruction is sent from the control device . The printer switches from the stacker 14 to the stacker 15 upon receiving this instruction. However, at this time, if there is paper in the stacker 15 or if there is another error, the stacker is not switched, and
Printing is continued while the state of the stacker 14 remains.

As described above, according to the present invention, the tape
Move the bull in the direction to be pulled out of the stacker body
Open switch and table stored in stacker
Simultaneously press the close switch to move in the direction
Switch the position of the switch lever, and
Switches the stacker used for
The function of the system can be improved without changing the appearance by adding a new switch to the tacker .
In addition, printer systems that do not have functions such as sample trays
Even Temu, the output result to be extracted operator, will be able to retrieve when you want to see, it is possible to improve the efficiency of business.
