Abstract

PURPOSE:To surely prevent a device from a malfunction by displaying an error message at the time of specifying a recording mode for executing a 2nd image recording when a paper discharging tray is opened, and denying the specification. CONSTITUTION:When a movable guide 106 is switched, a detecting switch 120 is engaged with a driving lever 107 rotated together with the guide 106 and driven and its detecting signal is sent to a controller 130 and an external device 140. When a both-face printing mode is specified, the external device 40 sends an instruction signal for displaying an error and inhibiting both-face printing to the controller 130 because only single side printing can be practically applied to the device. Receiving the instruction signal, the controller 130 displays an error message on a display device 150 and denies the specification of the both- face printing mode. Even if an operator specifies the both-face printing mode in error under the status that the straight paper discharging tray 101 is opened as it is, the device can be surely prevented from the malfunction.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a recording device such as a laser printer or a copying machine. The recording section is configured to control the designation of.

(Prior art) When attempting to add a double-sided print function or multiplex print function to a recording device that is capable of single-sided printing, there is a process to return the ejected recording paper to the image forming unit once the single-sided printing is completed. It is necessary to add a conveyance path, and in this case, a paper refeeding section is installed below the original recording radical (hereinafter referred to as the recording section) to refeed the recording paper to the image forming section, and further recording A transport unit for taking recording paper from the paper refeeding unit and delivering it to the paper refeeding unit is installed on the recording paper receiving side of the paper refeeding unit so as to straddle the recording paper output side of the recording unit. is commonly performed.

However, in such a recording device, when it is desired to perform single-sided printing on special recording paper with poor flexibility, such as bag-shaped recording paper, the single-sided recorded v1a tray that is manually set in the recording section or conveyance section is used. (hereinafter referred to as a straight paper output tray) is added, and when the straight paper output tray is closed, the conveyance path is opened to the paper refeeding unit side, and when it is open, the straight paper output tray is added. A movable guide is provided that is switched and operated to open the conveyance path on the paper tray side.

(Problem to be Solved by the Invention) However, when a straight paper ejection tray and a movable guide are provided as described above, the position of the movable guide can be changed by manual operation by the operator, so it is difficult to replace the straight paper ejection tray with the movable guide. If the operator selects the duplex print mode while the paper is open, the paper that should originally record images on both sides will be ejected to the straight output tray immediately after the first image is recorded, and will not be re-feeded. The paper is not sent to the paper section, resulting in a problem that the desired double-sided printing cannot be performed.

(Purpose) The present invention has been made in view of the above-mentioned conventional problems.The purpose of the present invention is that even if the operator specifies double-sided or multi-print mode, the recording paper only performs one recording operation. It is an object of the present invention to provide a recording device that can effectively prevent malfunctions such as ejection without being completed.

(Summary of the Invention) In order to achieve the above object, the present invention includes a recording section including one image forming section, and a recording sheet discharged from the recording section on which a first image has been recorded. A conveying unit for re-feeding the paper to the recording unit in order to perform the process, a paper output tray that is set in the middle of the transport unit so that it can be opened and closed, and a paper output tray that closes in conjunction with the operation of the paper output tray. a movable guide that is operated to open a conveyance path toward a side that refeeds the recording paper to the recording section when it is open, and to open a conveyance path toward the paper output tray when it is open; The apparatus includes a detection switch that detects a switching position of the movable guide, and a recording mode in which a second image recording is performed when the conveyance path is open to the paper output tray in response to a detection signal from the detection switch. A feature of the present invention is that a control means is provided for rejecting the designation of the recording mode when the recording mode is designated.

Therefore, even if the recording mode for recording the second image is specified while the paper output tray is open, an error message will be displayed and the specification will be rejected, ensuring that the device will not malfunction. Prevented.

(Example) An example of the present invention will be described below based on the accompanying drawings.

On the top surface thereof, there is an inverted paper ejection tray 6, and on the front side (on the left side in the figure) there is a straight paper ejection tray 101, which is a single-sided recorded paper 'v1a tray constituting a second paper ejection tray. Each is equipped with Further, the lower unit 1b has fixing rollers 7.7. It is composed of a paper feed separation roller 8, a horizontally extending conveyance path 9, etc., and an upper paper feed cassette 10 is detachably installed at the rear of the lower unit 1b (at the right end in the figure). A plurality of recording sheets 11 . . . are stored in the upper paper feed cassette 10 .

On the other hand, a paper refeeding section 12 is provided at the bottom of the recording section 1, and the paper refeeding section 12 includes a flapper 15, forward/reverse rollers 16, 16, paper feed separation roller 17, and a linear reversal pocket 18. , a conveyance path 19 forming an S-shape and connecting the reversing pocket 18 and the conveyance path 9. The structure includes an arc-shaped conveyance path 20 that merges with the conveyance path 19, and a lower paper feed cassette 21 is removably installed at the rear of the path. Recording paper 11... is stored.

At the front part of the paper refeeding part 12, a transport part 22 or its lower end is pivotally connected with a pin 23 so as to be openable and closable. It is always biased toward the closing side (toward the recording section L and paper refeeding section 12 side) by a tension spring 24 stretched therebetween, and the roller section 22a provided at the upper end of the roller section 22a is attached to the rail of the recording section L as shown in the figure. Surface 1c
is in contact with. Note that the conveyance section 22 is provided with an arcuate conveyance path 25 that connects the conveyance path 9 and the reversal pocket 18 .

Here, details of the straight paper output tray 101 will be explained based on FIG. 2.
01 is provided in order to eject recording paper with poor flexibility such as bag-shaped recording paper without jamming it. When the inverted paper ejection tray 6 is used for ejecting paper, it is closed on the paper ejection side of the recording section l as shown by the solid line in the figure, and a magnetic catcher (not shown) is provided. Its opening/closing is locked by any locking means. Note that this straight paper output tray lO1 has a rotating shaft 1.
Auxiliary tray 1 whose one end is rotatably pivoted at 03
04 is folded and stored, but this is used opened when loading long recording paper. or,
A hole 101a and a handhold portion 101b are formed in the straight paper discharge tray 101.
In the old part, each paper tray constitutes a surface.

On the other hand, a movable guide 106 is provided at the upper part of the transport section 22 and is rotatably mounted on a rotating shaft 105.
An operating lever 107 is integrally provided on the movable guide 106 in a protruding manner. The movable guide 106 is urged in one rotation direction (counterclockwise in the figure) by a tension spring 108 hooked to the operating lever 107, and the straight paper discharge tray 101 is closed. Sometimes it is at the position shown by the solid line. Note that this movable guide 106 is configured to either feed the recording paper 11 guided to the conveyance unit 22 by the seven gripper 4 of the recording unit 1 in the direction of the paper refeeding unit 12 (in the direction of the solid line arrow in FIG. 1), or to straightly discharge the paper. There is a switching guide for selecting whether to feed in the direction of the tray lot (in the direction of the broken line arrow in FIG.
And the paper receiver is formed with a surface 106b.

Further, the operating lever 1 of the movable guide 106 of the conveying section 22
07, there is a detection switch 1 such as a micro switch.
The detection switch 120 engages and disengages from the end of the operating lever 107 by rotation of the operating lever 107 in conjunction with the switching operation of the movable guide 106.
This causes the ON-OFF operation to detect the position of the movable guide lO6. This detection switch 120 constitutes a part of the error message display system shown in FIG. sent to.

Incidentally, in FIG. 3, 150 is a display device built into the recording apparatus.

Furthermore, a fixed lower guide 109 is fixedly installed adjacent to the movable guide 106 in the conveyance section 22, and when the straight paper output tray 101 is closed, the fixed lower guide 109 and the movable guide 106 are connected to each other. A passage 111 between the flapper 4 and the guide plate 110 and a passage 112 continuous with the conveyance path 25 are formed in the.

Next, the recording operation in the normal double-sided print mode that does not use the straight paper ejection tray 101 of this recording apparatus will be explained based on FIG. The recording paper 11 fed by the image forming unit 8 or 17 receives the first image recorded on its upper surface from the image forming unit 3, is conveyed along the conveyance path 9 in the direction of the arrow shown in the figure, and passes between the fixing rollers 7 and 7. By passing the first image, the first image is fixed. Note that the image forming unit 3
7 is a unit that includes an image forming mechanism for electrophotographic recording, which is composed of a photosensitive drum, an optical recording section, a developing device, a cleaner, etc. Here, from the image forming unit 3 to the fixing roller 7.
The portion in front of the image forming section will be referred to as an image forming section.

The recording paper 11 on which the first image has been fixed is guided by the flapper 4 and sent to the transport section 22 along the transport path 25, and then enters the paper refeed section 12 where it is moved by the forward/reverse rollers 16,
16, it is sent to the reversing part)-18, where it is reversed by the reversing action of the forward/reverse roller 16°16 and the switching action of the flapper 15 from the solid line position shown in the figure to the broken line position, and then reversed in its direction. The recording medium is sent back to the conveyance path 9 through the conveyance path 19 where the recording material is exposed to the air, and enters the recording section l again. The recording paper 11 that has been reversed and re-fed is then recorded and fixed with a second image on the side opposite to the side on which the first image was recorded in the image forming section, and then switched to the position shown by the dotted line in Figure 1. The sheets are guided by the flapper 4 and conveyed upward along the conveyance path 5, and are finally stacked one after another on the reversing sheet discharge tray 6.

Note that the above has explained the recording operation in the case of double-sided print mode, but in the case of single-sided print mode, the recording paper 11 is moved to the position indicated by the dotted line in the figure after the first image is recorded and fixed in the image forming section. The paper is guided by the flapper 4 which has been switched to , and is immediately sent to the reversal discharge tray 6 along the conveyance path 5 , and is sequentially planted on the reversal discharge tray 6 .

Next, a recording operation when printing on one side of recording paper with poor flexibility, such as a bag-shaped recording paper, will be explained with reference to FIG.

In this case, the recorded and fixed recording paper 11 is ejected and stacked on the straight paper ejection tray lot, but the operator hooks his/her finger on the handhold portion 101b of the straight paper ejection tray 101. When pushed open, the straight paper discharge tray 101 rotates about the rotating shaft 102 in the direction of arrow a in the figure and is set at the position shown by the broken line in the figure. If the recording paper 11 is long, the auxiliary tray 1 folded inside the straight paper output tray 101
04 about the rotating shaft 103 in the direction indicated by the arrow in the figure to expand it.

When the straight paper ejection tray 101 is pushed open as described above, the straight paper ejection tray 101 is
At c, the receiver of the movable guide 106 presses the part 106a, causing the guide 106 to rotate in the direction of the arrow C shown in the figure, about the rotating shaft 105 against the tensile force of the tension spring 108, and was initially at the solid line position l. This movable guide 106 is moved to the dotted line position.

Then, the paper receiving surface 106b of the movable guide 106 and the paper receiving surface 101d of the straight paper discharge tray 101 constitute a tray surface on which the recording paper 11 is stacked. At this time, the tip of the movable guide 106 fits within the hole 101a formed in the straight paper discharge tray 101, thereby avoiding interference with the straight paper discharge tray 101.

Moreover, when the movable guide 106 rotates to the dashed line position a shown in the figure,
A portion thereof overlaps with the fixed lower guide 109, or this overlapping portion is prevented from interfering with each other by configuring both in a comb-teeth shape.

Therefore, the upper paper feed cassette 10 or the lower paper feed cassette 2
After a predetermined image is recorded and fixed on one side of the recording paper 11 fed by the paper feed separation roller 8 or 17 from the recording paper 11 in the image forming unit of the recording unit l, the flapper 4 and the movable guide 106 are switched. The sheets are sent directly in the direction of the broken line arrow in FIG.
(See Figure 2).

By the way, when the straight paper output tray 101 is closed and the operator specifies the screen print mode, the first image is recorded and fixed on one side of the recording paper 11 by the image forming section of the recording section l. After that, the sheet is fed into the conveyance path 25 through the passage 111 between the flapper 4 and the guide plate 110 and the passage 112 between the movable guide 106 and the fixed lower guide 109, and is guided to the conveyance path 25 to be re-fed. Part 1
2, and thereafter the same recording operation as described above is repeated.

However, as described above, the position of the movable guide 106 can be changed by the operator's manual operation, so if the operator selects the duplex print mode with the straight paper output tray 101 open, images can be printed on both sides. After the first image is recorded, the recording paper 11 on which the image is to be recorded is immediately ejected to the straight paper ejection tray 101, and is not sent to the paper refeeding unit 12, so that the intended double-sided printing is not performed. The problem arises that it cannot be done.

Therefore, in this embodiment, the movable guide 106 or the second
If you can switch to the dashed line in the figure.

The detection switch 120 is activated by engaging with the operating lever 107 that rotates together with the movable guide 106, and sends the detection signal to the control device 130 and external device 140, as shown in FIG. At this time, if the single-sided print mode has been specified, the device can actually only print on one side, so it sends an error display and a command signal to prohibit double-sided printing to the external device 140 or the control device 130, and the control device 130 Upon receiving the command signal, an error message is displayed on the display device 150, and the designation of the double-sided print mode is not accepted.

In this way, even if the operator mistakenly specifies the duplex print mode with the straight paper output tray 101 open, an error message will be displayed and duplex printing will not be executed, ensuring that malfunctions of the apparatus are prevented. Ru.

According to the recording apparatus described above, double-sided printing is not possible when the straight paper output tray 101 is used, but special recording paper such as recording paper with poor flexibility that requires the use of the straight paper output tray 101 can be used for double-sided printing. Even if it is not possible to do so, there is almost no problem in practice. Again 1
In the above embodiments, a recording apparatus using electrophotographic recording in the image forming section was mainly explained. This includes I2 devices that have an image forming section that adopts this method. Furthermore, in the above embodiments, a recording unit capable of single-sided printing was described in which a paper refeeding unit for double-sided printing was added, but the present invention provides a recording apparatus that is equipped with a paper refeeding unit for double-sided printing. The present invention can also be applied to a recording apparatus equipped with a paper refeeding section that has two functions of double-sided printing and multiplex printing.

Further, in the embodiment, the forward and reverse rotation rollers 16, 16.
Although the paper refeeding section 12 is provided with a reversing section including a 7 flapper 15, a reversing pocket 18, etc., it may also be provided on the conveyance section 22, and the straight paper ejection tray 101 is also not limited to the recording section 1. However, there is no problem even if it is attached to the conveyance section 22. Furthermore, a straight paper output tray lO1
As for the movable guide 106, as in the above embodiment,
The application is limited only to a recording device that has a so-called shell-type recording section 1 formed by the lower units 101a and 101b, and a conveying section 22 that rotates following the recording section 1. However, these can also be applied to a recording device having any other configuration, and in this case, the processing section added below the recording section is not limited to the paper refeeding section, but also the third a.
It may be a tray or one with other functions.

(Effects of the Invention) As is clear from the above description, according to the present invention, even if the recording mode for performing the second image recording is specified while the paper output tray is open, an error message is displayed and This designation is rejected, so even though the operator has specified the recording mode for recording the second image, the malfunction in which the recording paper is unloaded after only one recording operation can be prevented. This has the effect of
