Abstract

PURPOSE:To house printed papers in a stacker by turning the printed face upwards or downwards as needed by providing a switch means by which to inverse and discharge the printed face of a printed paper. CONSTITUTION:The first stacker 12 to be turned in the direction of arrow A and coupled with an inverse path 13 and the second stacker 10 to house papers sent out of the inverse path 13 are provided. In case where the first stacker 12 is set at a position as shown by full line, the paper printed in a printing section 3 and discharged by a discharge roller 7 is stacked on the first stacker, and also where the stacker 12 is reset as shown by dotted line, turning in the direction of arrow A, the paper discharged by the discharge roller 7 is fed on the inverse path 13 and stacked on the second stacker 10 by a sending roller 9.

Description

Detailed Description of the Invention (a) Technical Field of the Invention The present invention stores printed sheets in a first stacker portion with the printed side facing up or with the printed side facing down as necessary. The present invention relates to a printing device that is respectively ejected to a second stacker section.

(b) Prior Art and Problems In copying machines, printers, and the like, sheets to be printed are fed out from a paper feed section and transferred to a printing section where predetermined printing is performed. After printing, the paper is ejected to a stacker section, and the printed paper is configured so that it can be easily taken out.

For example, a printer device is configured as shown in FIGS. 1(a) and 1(b). FIGS. 1(a) and 1(b) are side views schematically showing a conventional printer device.

As shown in (a), a printing section 3 is mounted on the top surface of a casing 1 that is supported by a pedestal 2 and houses a power supply section and a control section, and performs printing processing based on print data. A paper feed section 5 is fixed to one side of the printing section 3, and a stacker section 6 is fixed to the other side.

Therefore, the paper 4-1 stored in the paper feed section 5 is fed to the printing section 3, and after being printed in the printing section 3,
is discharged to the stacker section 6 by the rotational drive of. The ejected paper 4-2 is stacked 7, - However, in such a configuration, the print surface 4A of the paper 4-2 stacked on the stacker section 6 is the upper surface, and the paper 4-2 that was ejected first is stacked. is located at the bottom, so if the printing process is to print consecutive pages, the previous page and the next page are stacked upside down. Therefore, the paper 4-2 taken out from the stacker section 6 has the disadvantage that the stacking order must be changed.
The configuration shown in is now in use.

In the configuration of (a) above, a belt or a roller is provided to reverse the upper surface of the paper 4-3 discharged from the discharge roller 7, and a belt or roller is provided to reverse the upper surface of the paper 4-3 discharged from the discharge roller 7, and the reversing path 8 and the stacker from the reversing path 8 are transported by respective drives. A feeding roller 9 is added to the feeding section 10.

With this configuration, the printing surface 4A of the friend sheets 4-4 stacked in the stacker section 10 is the bottom surface opposite to that shown in (a), and when the printing process is page printing, the sheets are stacked in the order of the pages, so Paper 4 taken out by the stacker section
-4 does not need to be stacked differently.

However, if you want to immediately see the print result of the printed paper instead of page printing, it has the disadvantage that you have to take it out of the stacker section 10 and turn it upside down.

As described above, there is a problem in that it is not convenient to compare the printed results immediately or when comparing pages.

(c) Purpose of the Invention The purpose of the present invention is to eliminate the above-mentioned problems by storing the printed paper in the stacker section with the printed surface facing up or down, as required. It provides:

(d) Structure of the Invention The object of the present invention is to provide a first stacker unit for storing printed paper in such a printing apparatus, a reversing path for reversing the printed surface of the printed paper, and a reversing path for reversing the printed surface of the printed paper. and a second stacker section for storing the paper discharged from the printing section, and when the paper discharged from the printing section is set in the first stacker section, the paper is reset to the third-first stacker section. This is achieved by a printing apparatus characterized in that a switching means is provided for switching to transfer the paper to the respective reversing paths.

(e) Examples of the invention The invention will be explained in detail below with reference to FIG.

FIG. 2 shows an embodiment of the printing device according to the invention (a)
is a side view, and (b'Hb'') is an explanation.

As shown in (a), the first stacker section 12 that is locked on the reversing path 13 and rotated as shown by the arrow A and the a
The second stacker section 10 for storing the ejected sheets is provided, and the other features are the same as those described above.

Therefore, when the first stacker section 12 is set as shown by the solid line, the paper printed by the printing section 3 is ejected from the discharge roller 7, and the companion paper is stacked on the first stacker section. is rotated in the in direction of the arrow and is in the reset position as shown by the dotted line, the paper ejected from the ejection roller 7 is transferred through the reversing path 13 and transferred by the feed roller 9 to the 4th - 1st For example, switching the paper discharged from the discharge roller by setting and resetting the stacker unit 12 to the first stacker unit 12 shunting reversing path 13 is as follows (b
) This can be done with the configuration shown in (b2).

(bl) shows a microswitch 11 that comes into contact with the lower surface of the first stacker section 12, a plunger (not shown) driven by a signal from the microswitch 11, and a switching claw 14 that is rotated by the plunger as shown by the arrow. All are provided. The sheets discharged from the first stuffer 7 are transported in the direction of arrow C and stacked on the first stacker section 12.

On the other hand, when the first stacker section 12 is in the cut position at υ as shown by the dotted line in FIG. The paper comes into contact with the switching claw 14 and is transported in the direction of arrow 8, and is moved to the roller 1.
O stacker unit 12 sent to the reversing path 13 by 3A
The paper transport direction can be set in the direction of arrow C or arrow B depending on the time of 0 setting and reset.

A gear 16 is fixed to a central shaft 15 on which the first stacker section 12 is rotated, and a gear 17 is connected to a gear 17 that meshes with the gear 16.
8 are fixed together. When the first stacker section 12 is in the set state, the paper ejected from the ejection roller 7 is transported in the direction of arrow C as shown in the figure, but when the first stacker section 12 is rotated in the direction shown by arrow A1. When the gears 16 and 7 and 1 are set to the reset state, the gears 16 and 7 and 1 rotate as indicated by the arrows, respectively. Therefore, the switching claw 18 is rotated in the direction indicated by the arrow, and the paper discharged from the discharge row 27 is transferred in the direction indicated by the arrow B as described above.

With this configuration, if you want to see the printing results immediately, you can set the first stacker section 12 to the set state, stack the printed sheets on the first stacker section 12, and see the printing results. Further, in the case of page printing processing, by setting the first stacker section 12 to a reset state, the sheets after printing are stacked on the second stacker section 10 and arranged in the page order.

(f) Detailed Description of the Invention As described above, the present invention provides a first stacker unit 12 in which stackers are stacked with the printed side facing up, and a second stacker unit 12 in which stackers are stacked with the printed side facing up.
A stacker section 1o is provided, and the paper after printing is discharged to the first stacker section 12 when the first stacker section 12 is set, and to the second stacker section 10 when the first stacker section 12 is reset. It is something. This allows you to see the print results immediately and arrange them in the order of the pages, so you can deal with both cases and have great practical effects.
