Abstract

PURPOSE:To enable an error to be processed on the automatic paper feeding device side without exercising an influence on the power source of a recording device body and recording data, by providing a detecting means for a paper feed error, a displaying means, a returning means, and a transmitting means to a recording device. CONSTITUTION:When a paper feed error detecting sensor 8 does not detect a recording paper 1, the occurrence of an error is detected and simultaneously a motor for driving a paper feed roller 2 is brought to a stop. Thereafter, a control part 11 causes a display part 9 to display an error through flickering of a LED. In which case, an interface 10 reports the occurrence of an error to a recording device body, and after an operator eliminates the cause of an error, a key switch 13 is depressed to return a device to a main routine. This enables an error to be processed on the automatic paper feeding device side without exercising an influence on the power source of the recording device body and recording data.

Description

[Detailed Description of the Invention] [Technical Field] The present invention relates to an automatic paper feeder, and more specifically, the automatic paper feeder can process detection of paper feed failure and/or out-of-paper state, restoration to original state, etc. The present invention relates to an automatic paper feeder such as the above.

[Prior Art] An automatic paper feeder is a device that is attached to various recording devices and automatically feeds recording paper.

This automatic paper feeder is usually used as an option for recording devices, so paper feed errors may occur.

When an out-of-paper condition or the like occurs, it is determined by the main body of the recording apparatus and displayed on the main body.

If a paper feed failure or out-of-paper condition occurs as described above, in order to resolve the issue, you must turn off the power to the recording device, remove the cause, and then turn the power back on. Ta.

When such a structure is adopted, the above-mentioned inconvenient condition is determined and displayed only on the recording apparatus main body side, so that the part where the inconvenient condition occurs is unclear.

Also, in order to eliminate the cause of any problems that may occur with the optional automatic paper feeder, it is necessary to turn the power on and off on the device itself.

As a result, inconveniences such as erasure of recorded data on the recording apparatus main body side occurred.

[Purpose] The present invention was made in order to eliminate the above-mentioned drawbacks of the conventional paper feeder. The purpose is to provide a paper feeding device.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

Figure 1 and the following diagrams explain one embodiment of the present invention.
The figure shows the state in which the automatic paper feeder and the recording apparatus are connected.

In FIG. 1, the reference numeral l is recording paper exemplified as cut sheet paper, and it is in the paper feed tray 3 on the automatic paper feeder side.
The sheets are stacked inside the paper and are sent out by a paper feed roller 2.

The fed recording paper is guided by a paper guide 4 on the recording apparatus side, wound around a platen 5, and fed to a cue position.

A recording rack 6 is arranged corresponding to the platen 5.

In FIG. 1, the reference numeral 7 indicates the recording paper that has been guided to the cue position.

Further, the sensor indicated by the reference numeral 8 is a sensor for detecting recording paper, which is provided on the automatic paper feeder side, and detects, for example, that the leading edge of the recording paper l has been guided to a predetermined position, sends the detection signal to.

On the other hand, FIG. 2 shows a block diagram of a control circuit on the automatic paper feeder side.

In FIG. 2, the reference numeral 8 indicates the sensor described above, the reference numeral 9 indicates the display section, 10 indicates the interface section for transmitting and receiving signals to and from the recording apparatus, 11 indicates the control section, 12 indicates the paper feed unit, ), 13 are key switches, and each control unit 1
1 and controlled by a control unit 11.

Next, the operation of this embodiment configured as above will be explained with reference to the flowchart shown in FIG.

Inconveniences (hereinafter referred to as errors) that need to be detected in an automatic paper feeder include paper feeding failures and paper out states where the recording paper is not fed at all or is not fed to a predetermined position for some reason.

In any case of an error, the recording paper is not guided to the position of the sensor 8 shown in FIG. 1, and therefore can be detected by the sensor 8.

Specifically, the occurrence of an error is detected by a method of determining an error if the sensor 8 does not detect the recording paper even if the paper feed roller 2 is rotated by a predetermined amount.

That is, as shown in FIG. 3, the apparatus starts, a normal recording main routine begins, and in the middle of this, step S is performed.
If the occurrence of an error is detected by the method described above in step S2, the control section turns off the motor for driving the paper feed roller in step S2, and then, in step S3, the control section displays an indication of the occurrence of an error on the display section 9 by blinking an LED or other means. Let's do it.

Next, in step S4, the operator notifies the main body of the recording apparatus that an error has occurred, and removes the cause of the error. After removing the cause of the error, in step S5, the operator presses the key switch 13 to clear the error, thereby returning to the main unit. Return to routine.

In this way, error processing can be performed only on the automatic paper feeder side without affecting the main body of the recording apparatus.

As for the error recovery method, for example, in the case where a plurality of paper feed trays are used, the tray that was selected at the time of the error occurrence may be selected again after the error is cleared.

Further, as the display means such as an LED which is blinked when an error occurs, one that normally displays the selected tray may be used.

Further, the key switch 13 for canceling an error may also be used as a switch normally used for selecting a tray or changing a mode.

[Effects] As is clear from the above description, according to the present invention, means for detecting paper feeding errors, error display means, and error canceling means are provided on the automatic paper feeding device side, and the occurrence of errors is detected by the recording device. Since it has a structure that has a function to notify the user, there is no need to turn off the power to the recording device itself, unlike conventional methods, and there is no problem such as erasing recorded data, and the error location can be clearly identified. It becomes possible to
