Abstract

PURPOSE:To visually confirm a recording condition on a conveying course by enabling means of conveying sheets of recorded paper body to a storing part to be moved at a first conveying speed and at a second conveying speed which is slower in order to confirm the recording condition. CONSTITUTION:When a push button switch 39 for carrying out the direction of sample print is pressed while a printer is printing information on the n-th page, sheets of paper Pn-1, Pn exist on a conveying course and information for the (n-1)-th and n-th pages is being printed on them respectively. The sheet of paper Pn-1 is conveyed according to the information of its destination, while the sheet of paper Pn is stopped on a conveying belt 6. Since the sheet of paper on the n-th page is placed on the conveying belt with its printed surface faced upward, its contents can be easily confirmed. When the switch 39 is pressed, printing for pages ahead of an (n+1) page is being forbidden.

Description

[Detailed description of the invention] Technique + tr field The present invention is a method for checking the recording state of a dirty paper sheet and storing it.
1; relates to a recording device capable of recording without taking out a paper sheet.

BACKGROUND OF THE INVENTION High-speed copying machines or laser beat printers A9 are often used in combination with an output paper stacking device such as a sorter or stacker in order to store a large amount of output paper. However, with these high-speed machines, it is difficult to check the print shape while it is being conveyed, so the printing operation is temporarily stopped and the paper is taken out from the output paper stacking device. This forced the user to check the printed content, which resulted in a reduction in throughput. In order to solve this problem, it has been proposed to provide a separate storage section in addition to the regular print section to produce so-called sample prints. However, this method has disadvantages in that it is expensive and requires extra paper.

Purpose The present invention aims to eliminate the above-mentioned drawbacks, and has the purpose of making it possible to visually check the recording state of sample prints and sometimes paper sheets on which sample prints have been carried out along the conveyance path, and to make it possible to visually check the recording state of paper sheets on which sample prints have been carried out, and to make it possible to visually check subsequent prints. In addition, when the relevant page is required as a sample, when the recorded SI paper is taken out from the conveyance route, by recording the recorded information on the taken out recording paper again on the subsequent paper sheet, An object of the present invention is to propose a recording device that eliminates page loss and does not perform wasteful printing.

Also, conveyance route 1. We propose a recording device that enables more reliable confirmation of the recording state by stopping the sample print paper at the same time.

Embodiment F An embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a diagram schematically showing a paper conveyance path in an embodiment of the present invention. The following is an explanation based on the visit.

When paper is fed from the cassette 2 loaded in the printer 1, the electrical output from the page information output circuit 22 shown in FIG. After it is converted into an optical signal and a static latent image is formed on the surface of the I-ram of the photosensitive tram 3 by this optical signal, the image (recorded information) developed with I-ner is rolled onto paper and is Heavy clothing I.

After that, the IJ1 paper roller 4 releases the image 1fii one by one with the image 1fii facing upward.

The paper subjected to υ[111 is fed to a stacker R (hereinafter abbreviated as stacker) 5. The fed paper is stacker 5 person 1
It is held between one part of the pulley 20 and the presser roller 19, and is conveyed by the conveyor belt 6 to the water in the direction of the arrow.

At the end of the heald there is a horizontal deflector 7 which deflects this water.
By creating the water-+1 deflector 7 depending on whether or not the solenoid 29 connected to the li deflector 7 is energized, it is controlled whether the water is further sent in the horizontal direction or in the vertical direction. In FIG. 1, the paper is shown to be fed in the vertical F direction.

The paper is conveyed by a conveyance kite 8 and a feed roller, and is passed through a width-cut eastward deflector loa and a fixed vertical deflector 10.
The conveyor belt (b) and 61- are reversed and guided to two storage sections. In FIG. 1, the solenoid 3o connected to the vertical deflector is in a non-energized state, and the paper is not branched at this deflector section, but is sent in the -F direction, branched to the left by the vertical deflector tab, and then transferred to the paper discharge roller Ilb into four nozzles. 1 is issued.

Conveyor belt 6, drive roller 9, υ1 paper roller 11a, l
lb is 01 of the printer 1 via a drive transmission means (not shown).

When the pallet 13 mounted on the fork 1- is not loaded with paper, it reaches a specified height 51 and stops.

How many sheets of paper are output from the paper roller 11 with the printing side facing down?
The front end of the conveying force is regulated by the alignment chi l' l6 and descends onto the pallet 13. A photosensor consisting of a light emitting element 23 and a light receiving element R-24 for detecting the paper surface is installed in the alignment kite part, and the sensor output is cut off when the paper 15 loaded on the pallet 13.1-: exceeds a certain height. The change in the signal drives the elevator motor 28 to lower the page by a constant 111F. When the load zz1 increases and the elevator repeatedly descends and descends until it reaches the specified position in the stroke, it is detected that the deck is fully loaded, and subsequent access to paper is prohibited.

When the paper is removed from the full container I2 and the container 12 is reloaded, the empty detection sensor of the container 12,
That is, the sensor consisting of the light-emitting element 25 and the light-receiving element 26 detects that the paper is missing, and the paper is detected to be accessed to the deck section. .

Recording device with the following configuration: n on the printer l side in yl
A sample switch 112 (3 in Fig. 2) instructs sample printing when printing page information.
The operation when the button (corresponding to 9) is pressed will be explained.

There are papers Pn-1 and Pn on the conveyance path J2, and paper Pn-1
, Pn contains information about the (n-1)th page and n page l. This paper Pn-1 is conveyed according to the destination information, and the next paper Pn is stopped at a position on the conveyor belt 6- shown in FIG. In other words, since the nth page of paper is placed on the conveyor belt with the printed side facing up, it is extremely easy to check the contents.

Printing of pages (n+1) and beyond after the sample print switch is pressed is prohibited, and there is no subsequent paper.

Now, after the paper Pn is stopped for a certain period of time, it is transported again and is branched according to the destination information, and at the same time the paper Pn+1
, Pn+2... are printed from page (n→-1). If the operator needs n pages of information, he opens the door 37 and takes out the paper Pn. When the paper Pn is taken out, the entrance sensor (1', 11) consisting of the light emitting element 21 and the light receiving element 25 changes from the state in which the light beam has been blocked by the paper (in this state, the primary is turned on). , the light beam 1 is transmitted,
The stacker 5 side instructs the printer l side again whether to print from the nth page.

In order to prevent danger, the conveying section is not driven when the door 37 is in the open state.

The details of the operation during this time will be described below with reference to the control flowchart 1 for printing samples on the stacker 5 side in FIG. 4 and the control flowchart for printing samples on the printer I side in FIG. 5.

The stacker 5 first switches the sample switch 1 in step 302.
It is checked whether or not there is a push button input of No. 12, and if there is no push button input, normal transport and storage control is performed. When it is detected in step 302 that the sample switch 112 is on (push button input), the process proceeds to step 303, and the printer 1 is notified that the sample switch 112 is on.

Then, in step 304, the timer To is set to ensure that the paper recorded before the sample switch 112 is turned on passes through the population sensor 111 (timer To), and in step 305
Then, in step 306, the paper being conveyed is branched and conveyed according to the destination information and waits for the To timer time to elapse. When 10 hours have elapsed, the process advances to step 307 and waits until the sample-printed paper blocks the population sensor 111. When the sample print paper blocks the population sensor 111, step 308
Wait for 11 hours until the paper is conveyed to the bottom of door 37. T. When one hour has passed and the paper has been conveyed to the lower part of the door 37, in step 309, the conveyor belt 6 drive latch 115 (corresponding to FIG. 2, 32) is turned off, and the conveyor belt is stopped 1-.

Then, in step 310, the sample print paper is
i(set timer T2 for 4 hours T2, step 3
11 and step 312, the timer r, II! j, the door 37 is opened and the door switch 113 (second
(corresponding to 38 in the figure) is turned off. When it is detected in step 311 that the door switch 113 is off, the process proceeds to step 313, and the sample print paper is transferred to the conveyor belt 6.
The eye sensor 111 is monitored to see if it is turned off. If the person 1-1 unit 111 is not turned off, the process returns to step 311 and steps 311 and 313 are executed.

If the sample print paper is taken out here, the process advances to step 314, where the door 37 is closed and the door switch 1 is removed.
13 is turned on, and when the door 37 is closed, in step 315, the printer I is requested to execute the print I again from the current page because the sample print paper has been taken out, and then in step 317 clutch 1
15 is turned on, and the conveyor belt 6 is driven one revolution.

If the door switch 113 is not off in step 311 and it is detected in step 312 that 112 hours have elapsed, the process proceeds to step 314, where the visual confirmation of the sample print is completed and the sample print paper has not been taken out. A request is sent to printer 1 to start printing from the next page of the sample print, and step 317
The clutch 115 is turned on, and the sample print paper is transported and stored according to the preset destination information.

The second part is the control on the stacker 5 side, and the control on the printer l side during this time will be explained below with reference to the control flowchart in FIG.

When the sample switch 112 of the stacker 5 is pressed during normal printing and the sample print I is notified from the stacker 5, the printer 1 proceeds from step 321 to step 322, and checks whether or not an image is currently being formed on the recording paper. ,
If the image is currently being formed, the process advances to step 323, where the image information currently being formed is recorded on recording paper and this is used as a sample print. If image formation is not currently in progress, the process advances to step 324, where the image for the next page is recorded on the next recording paper, and this is designated as sample print I. and step 323,
324 and step 325, the image output of the subsequent page is prohibited, and the process proceeds to steps 326 and 327, where the printer I is placed in a wait state. After checking the sample print on the stacker 5 side, the 4th one is placed on the printer l side.
Step 315 or Step 31 in the flowchart
6 print yellow request is output. When this print request is manually input to printer 1, step 327 is followed by step 32.
Proceeding to step 8, it is determined whether to print from the current page or from the next page, and in the case of a print request from the current page, printing from the current page is executed at step 329,
Step 330 in the case of a print request from the next page
Proceed to and print from the next page.

As mentioned above, in this embodiment, when a sample print command is issued, the print of the page before the corresponding output page is guided to the output paper storage section, and the conveyance path that is conveying the corresponding output paper is output. It is stopped 1 before the storage M part N is inserted, the corresponding page can be visually confirmed 1-1 from the outside, and printing of subsequent pages is temporarily prohibited. By doing this, it becomes possible to check the contents of the required pages without providing a tray for outputting the pages.

In addition, if the corresponding page is required as a sample, when the paper is taken out from the conveyance path, the paper presence/absence sensor is activated and rotated.
By controlling the page to print ([!), it became possible to print without page loss.

Now, from what has been described so far, it is clear that the printer and the stacker may have the same frame structure and may be driven and controlled by one CPU. Furthermore, although the present embodiment has been described with respect to a laser beam printer, it goes without saying that the present invention can also be applied to a copying machine or other printer device that handles paper sheets. Further, the conveying system in the conveying means is not limited to starting/stopping at different timings, but may be started/stopping at the same timing. It is also obvious that switches and sensors can be combined as appropriate to provide additional information for notifying sample prints or for notifying that sample prints have been taken out.

In addition, we explained an example in which sample printed paper is stopped in the conveyance system, but it is also possible to change the conveyance system to a printed state! The control may be such that it is driven at a low speed that allows confirmation of c; and is stopped by specific human power such as opening the door. If there is an additional device that controls the consistency of printed page information depending on whether paper is removed or not, various peripheral modifications are possible.

Effects - 1 - As explained above, according to the present invention, there is no need to worry about sinking a new υ1 Degawa tray in order to confirm the record F;
A recording device with a very simple configuration is realized.

In addition, if the sample printed output paper '~' is not set separately, it can be treated as regular output without any unnecessary printing, and efficient recording can be achieved. A recording device that is also effective in managing the confidentiality of information will be realized.
