Abstract

PURPOSE:To automatically vary a loading position of a recorded medium without a switching command, by providing a loading means for loading the recorded medium and a switching means for switching automatically the loading position of the loading means in accordance with input information. CONSTITUTION:When a transfer of an output image data is ended, whether the data still remains behind in a receiving buffer 202 or not is checked, and in case when the data remains behind, it is shown that the next page is inputted continuously therefore, a shift of a discharge paper tray 113 is not executed but a processing of the next page is executed. In case when no data remains behind, it is decided that a series of print jobs is ended once at that stage, a signal is sent to a discharge paper tray shift motor driving circuit 206, and the discharge paper tray 113 is shifted in the direction reverse to the present position. In such a way, paper can be loaded automatically by shifting it alternately to the discharge paper tray 113 by a unit of a series of print jobs, without troubling a hand of an operator or a data implementor.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device having a recording medium loading mechanism.

[Conventional technology]

2. Description of the Related Art Conventionally, some devices of this type have a mechanism for loading recorded media in a manner that shifts the loading position to separate and load recorded media.

This switching of the loading position was conventionally performed by issuing a switching command in the information source.

[Problem that the invention is trying to solve] However,
In the conventional example described above, it was difficult to insert such a switching command into existing information.

Furthermore, when handling information targeted at a plurality of recording devices, it is difficult to insert commands for functions unique to a certain recording device into the information.

[Means for solving the problem (and operation)] The present invention provides means for monitoring the input state of information from an information source, detects that the information is interrupted, and automatically records the information without a switching command. The loading position of the finished media can be changed.

〔Example〕

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a sectional view showing the internal structure of a laser beam printer (hereinafter referred to as LBP) of this embodiment. In FIG. 1, 100 is an LBP main body, which converts character information supplied from an externally connected host computer into a corresponding character pattern and forms an image on paper, which is a recording medium.

10.1 is a printer control unit that controls the entire LBPIIO and analyzes character information etc. supplied from the host computer. The printer control unit 101 mainly converts character information into a video signal of a corresponding character pattern and outputs the video signal to the laser driver 102 . Laser driver 1
02 is a circuit for driving and controlling the semiconductor laser 103, and the semiconductor laser 10 is controlled according to the input video signal.
The laser beam 104 emitted from 3 is switched on and off. The laser beam 104 is swung left and right by a rotating polygon mirror 105 and irradiated onto the electrostatic drum 106.
A latent image of a character pattern is formed on 6. ``This latent image is developed by a developing unit 107 around the electrostatic drum 106 and then transferred to the paper. Cut sheet paper is used as the paper, and the cut sheet paper is stored in a paper cassette 108 attached to LBPloo, taken into the device by a paper feed roller 109 and transport rollers 110 and 111, and supplied to an electrostatic drum 106. . The paper onto which the character pattern has been transferred is discharged to a paper discharge tray 113 after the pattern image is fixed in a fixing device 112 .

Reference numeral 114 denotes a paper discharge tray shifter for shifting the paper discharge tray left and right, and is generally composed of a motor and a cam. The paper output tray shifter is driven by a paper output tray shift motor drive circuit 206, which will be described later, and its 0N10F
F control is performed by a signal from printer control unit lO1.

FIG. 2 is a block diagram showing the configuration of the printer control unit 101 described above. In Figure 2, 200 is LB
This is a central processing unit (hereinafter referred to as CPU) that controls the entire P100 and analyzes and edits character information etc. supplied from the host computer 210. 201 is an input interface circuit that sends and receives data to and from the host computer 210, and when character information and control commands are input from the host computer 210, it outputs an interrupt signal S01 to the CPU 200 to notify the existence of the input. , and sends the input information signal D01 to the CPU 200. 20
2 is a receiving buffer for temporarily storing input information supplied from the host computer 210 via the CPU 200. That is, the CPU 200 receives the input information DOI by the input interrupt processing program activated by the interrupt signal Sol.
is read and stored in the reception buffer 202.

203 is a program ROM that stores a printer control program for the CPU 200 shown in FIG. 3, which will be described later; 204
is a font memory that stores various character patterns corresponding to character codes in input data input from the host computer 210, and is composed of a general ROM. 20
An image memory 5 stores an output image for one page in the form of a bit image, and is composed of a general RAM. A character pattern corresponding to the input data taken out from the reception buffer 202 is read from the font memory 204 and written to a predetermined print position on the image memory 205, thereby forming an output image for one page.

Reference numeral 206 denotes a paper discharge tray shift motor drive circuit that drives the motor in the paper discharge tray shifter 114. By applying a signal from the CPU 200 according to the printer control program, the motor is moved to shift the paper discharge tray left and right. In this embodiment, when the signal is turned ON, the paper discharge tray is shifted to a position opposite to the current position (for example, if it is on the right) (for example, to the left).

207 is an output interface circuit 208 which converts the image data sent from the image memory 205 into an image signal SO2.
This is an image signal generator that outputs to. The output interface circuit 208 is a circuit that outputs various control signals and image signals to the LBP printing mechanism section 209. The output interface circuit 208 outputs various control signals and image signals to the LBP printing mechanism section 209.
9, a series of printing processes such as paper feeding, rotation of the electrostatic drum 106, and activation of the laser driver 102 are executed.

Next, the CPU 2 stored in the program ROM 203 shown in FIG.
This will be explained according to the flowchart of the printer control program No. 00.

First, in step 5301, the entire LBP 100 is initialized, and in step 5302, it is checked whether a group of input data from the host computer 210 is stored in the reception buffer 302. If there is input data in the reception buffer 202, 1. In step 5303, the oldest one is extracted, and in step 5304, its contents are checked.

If the input data is a character code, the process advances to step 5305, where the character pattern corresponding to the character code is retrieved from the font memory 204 and written to the current print position in the image memory 205 to update the print position. . Then, the process returns to step 5302 to continue processing the next input data.

When the input data is checked in step 5304, if the input data is a control code FF (form feed) indicating the end of one page, writing of one page's worth of input data to the image memory 205 is completed here. This indicates that the output image is completed, so steps 3306 to 3
Proceed to output processing in step 09.

First, in step 8306, the printer activation signal SO3 is turned on to activate the LBP printing mechanism unit 209, and in step 5307, one page of output image data prepared in the image memory 205 is transferred to the image generator 207, Execute printing. When the transfer of the output image data is completed, it is checked in step 8308 whether there is any data remaining in the reception buffer 202 (that is, whether data from the next page onward has already been transmitted from the host computer 210). If there is data remaining in the reception buffer 202, this means that the next page is being input continuously, so the paper output tray is not shifted and the process continues in step 5.
The process returns to step 302 to process the next page. Step 83
If no data remains in the receiving buffer 202 in step 5308, it is assumed that the series of print jobs has ended, and the process proceeds to step 5309, where a signal is sent to the output tray shift motor drive circuit 206 to shift the output tray. Shifts the current position in the opposite direction. Then step 53
Return to step 02 and process the next page.

As described above, by checking the input status of the next print information when conveying the paper, the instruction to shift the paper discharge tray is automatically issued. As a result, sheets can be alternately shifted and stacked on the paper ejection tray in units of a series of print jobs without bothering the operator or data creator, and output paper can be easily sorted.

[Other Examples]

Although this embodiment was applied to a laser beam printer, the present invention is not limited to this, but can also be applied to an LED printer.

It can be applied to printing devices using various printing methods such as thermal transfer printers and serial dot matrix printers. Furthermore, it can be applied not only to printing devices but also to other recording devices. or,
In devices such as dot matrix printers that print on paper one character at a time or one line at a time, after each page has been printed on the paper, it is checked to see if there is any more data.
This will select the shift position of the paper output tray.

Furthermore, in this embodiment, the shift position of the paper output tray is determined by simply checking whether there is data for the next page at the start of printing. In the form where a command (job separator) is attached, the job Φ
The paper discharge tray may be shifted when the separator is detected. In this case, although the data was continuous pages, the input data was sent with a gap between pages for some reason on the host side, so it is possible to prevent malfunctions such as shifting of the paper output tray during the job.

〔Effect of the invention〕

According to the present invention, when input information is recorded, it is possible to provide a recording apparatus that automatically selects the ejection and loading position of the recording medium according to the input information.
