Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording device such as a printer using electrophotography.

[0002]

2. Description of the Related Art Printers using conventional electrophotographic technology, for example, laser beam printers, liquid crystal printers, LEs.
In many D printers and the like, the recording paper is ejected in a face-up state (hereinafter referred to as face-up) with the side on which information is recorded facing up.

This is because the recording paper (cut paper) immediately after the information is printed must be supported and conveyed from below against gravity, and the surface on which the information is printed is slid from below before the fixing process. This is because rubbing and supporting causes fading and dirt of information.

Further, in a recording apparatus in which the surface on which information is recorded is discharged facedown (hereinafter referred to as "facedown"), recording is performed faceup once, and a print image is fixed, and then a conveyance path is formed. Among them, it was equipped with a mechanism for turning it face down and discharging it.

[0005]

[Problems of the Prior Art] In the conventional recording apparatus having the above-described structure, the face-up discharging device can select only face-up, and face-down discharging can select only one face-down, and both are selectively performed. I couldn't do that.

Therefore, in the face-up recording apparatus,
The order of recorded pages was reversed, and it was necessary to rearrange the order after printing. Further, in the face-down recording apparatus, there is an inconvenience that the recording paper has to be turned over one by one when it is desired to confirm the print quality of the printed record information.

Further, in the face-down discharge, the recording paper is turned over in the conveying path, so that thick thick paper etc., which has strong stiffness, is stuck in the conveying path, causing a failure.

[0008]

SUMMARY OF THE INVENTION In view of the above conventional drawbacks, it is an object of the present invention to provide a recording apparatus capable of selectively ejecting recording paper face up or face down in accordance with an instruction from a host device. ..

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is a recording apparatus for recording on a recording sheet according to a recording signal sent from a higher-level device, with the recording surface of the recording sheet facing up. A first placing section for placing a sheet of paper, a second placing section for placing the recording sheet with the recorded surface of the recording sheet facing downward, and the recorded recording sheet as the upper device. Selection means for selectively ejecting to one of the both mounting portions in accordance with the instruction signal from.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of an electrophotographic printer showing an embodiment of the present invention.

In FIG. 1, the electrophotographic printer sequentially conveys a recording section 2 for forming recording information on a photoconductor 1 and a recording paper 3 in timing with the recording information formed on the photoconductor 1. The sheet feeding section 4 includes a sheet feeding section 4 and a transport section 8 having a selecting unit 7 for selecting the recording sheet 3 between a first placing section 5 and a second placing section 6.

The recording unit 2 is composed of known technical means, and is an optical charger 9 for uniformly charging the photoconductor 1 arranged around the photoconductor 1 and an optical device for recording recorded information on the photoconductor 1. A recording head 10, a developing device 11 for developing the electrostatic latent image formed on the photoconductor 1, a transfer device 12 for transferring the developed recording information onto the recording paper 3, and a transfer process using the transfer device 12. The optical recording head 10 in this embodiment uses a liquid crystal optical shutter in which a large number of micro-shutters are assembled in the main scanning direction. ing.

The present invention is not limited to this, and can be applied to an optical recording head using a laser beam or an LED. The paper feed unit 4 includes a cassette 14 in which a large number of recording papers 3 which are cut papers are stacked, a paper feed roller 15 that takes out and conveys the recording papers 3 one by one from the top, and guides the conveyance direction of the recording papers 3. The guide plate 16 is provided, a timing roll 17 that conveys the recording information on the photoconductor 1 to the transfer portion at a timing and a manual feed port 18, and is formed on the photoconductor 1 by a signal from a control mechanism (not shown). The recording paper 3 is conveyed at the same timing as the recorded information.

Further, the manual insertion port 18 is an insertion port for inserting cardboard or the like, which is not suitable to be stored in the cassette 14, one by one. In the above embodiments, the case where the cut paper cut into a predetermined size is fed has been described, but it goes without saying that the present invention can be applied to recording paper in which roll paper is appropriately cut.

The conveying section 8 fixes the recording information on the photoconductor 1 in a face-up state with the recording paper 3 transferred by an unillustrated transfer section, and fixes the transferred recording information by heating or the like. The fixing roll 20, the selecting means 7, and a plurality of conveying roll pairs 21a, 21b, 21c, 21d, 21e, 2
It is composed of 1f and the like.

Here, the recording paper on which the recording information is recorded and before the fixing process must be held and conveyed in a face-up state in order to prevent the image from being soiled or blurred.

The recording paper 3 (not shown) received on the guide plate 19 in the face-up state is subjected to fixing processing by the fixing roll 20, and then is conveyed by the conveying roll pair 21a by the guide plate 22,
Selection means 7 provided between 23 and 23 so as to be semi-rotatable by a shaft 24
It is transported to the area (see Figures 2 (a) and 2 (b)). The selection means 7 is
It can be automatically switched by a signal from a control mechanism (host device) (not shown) as a higher-level device.

As shown in FIG. 2 (a), when the selecting means 7 is lowered, the recording paper 3 is raised by the pair of conveying rolls 21b to 21e and discharged facedown to the second mounting portion 6. It

As shown in FIG. 2 (b), if the selecting means 7 is moved up about the shaft 24, the recording paper 3 is faced up substantially straight by the pair of transport rolls 21f. It is discharged to 5.

As described above, according to the recording apparatus of the present invention, the recording paper (cut sheet) is selectively supplied to the first placing section 5 and the second placing section 6 according to the designation from the host device. In addition to being able to discharge it, face-up and face-down can be selected at the same time.

Further, by manually feeding the paper,
If face-up discharge is selected, the recording paper is conveyed in a substantially straight line, so that printing can be performed without fear of paper jam even if the paper is strong or thick.

Further, the manually fed recording paper is always discharged to the face-up first placing portion 5, and the recording paper fed from the cassette is face-down second placing portion. It is also possible to preset the selection to discharge to 6.

[0023]

According to the recording apparatus of the present invention configured as described above, the printing surface of the recording paper can be selected face-up or face-down according to the designation from the host device as the host device and ejected. I can.

Therefore, when printing on thick thick paper, face-up with a large radius of curvature of the conveying path can be selected to prevent paper jamming in the conveying path.
If face-down discharge is selected, the inconvenience of page alignment of recording paper after printing can be eliminated, and the recording paper can be easily arranged.
