Here, the reversal / paper discharge sensor 22 is arranged on the downstream side of the reading position in the document conveyance path, and the marking position is set slightly downstream of the position of the document detected by the reversal / paper discharge sensor 22. Further, the stamp 50 that performs the printing operation at the marking position operates on the same principle as the electromagnetic solenoid. That is, as shown in FIG. 3, the stamper 51 is fixed to the plunger portion of the solenoid, and the main controller 10
When the print signal from 0 is turned on, the stamper 51 projects and stamps the original document on the rib 40. When the printing signal is turned off after the stamping is completed, the stamp 50 returns the stamper 51 to the position shown in FIG. This return operation is
It may be performed by the self-weight of 51, or may be forcibly returned by the force of the spring. In addition,
The stamper 51 is held at a position where it does not project from the insertion hole 43 into the conveyance path during the standby of the printing operation.

Next, the structure of the stamp unit in the automatic document feeding unit of this embodiment will be described. FIG. 5 is an exploded perspective view of the vicinity of the mounting portion of the opening / closing cover in the automatic document feeding unit of the present embodiment, and FIG. 6 is a perspective view of the opening / closing cover and the stamp storage portion of the automatic document feeding unit of the present embodiment. 60 and 61 are guide plates 42
Is an exterior member that covers the back surface of the automatic document feeder unit of the present embodiment. The output unit cover 60 is screwed to the unit body, and other automatic document feeders that are not equipped with the stamp 50 are used. In the paper unit, the paper exit cover 61
Is screwed to the unit body. 62
Is a stamp accommodating portion that protrudes outward from the paper discharge portion cover 60, and supports the opening / closing cover 63 so as to be openable and closable. A space for accommodating the stamp 50 is formed in the stamp accommodating portion 62, and the stamp 50 is supported by a bracket 54 fixed to the inner surface of the opening / closing cover 63. In addition, the stamp 50 is connected to the main control unit 100 by a harness 53.

In the stamp housing 62, an opening 64 is formed so as to face the insertion hole 43 of the guide plate 42, and a cover detection sensor 65 composed of a photo interrupter or the like is arranged. Further, a projecting piece 66 and a locking claw 67 are formed on the inner surface of the opening / closing cover 63, and by moving the opening / closing cover 63 to the closed position, the locking claw 67 is locked in the locking hole of the stamp housing portion 62.
68 is hooked to hold the open / close cover 63 in the closed position. As means for holding the opening / closing cover 63 in the closed position, other than the hook claw 67 and the hook hole 68, a means for holding by magnetic force of a magnet may be used. When the open / close cover 63 is held at the closed position, the cover detection sensor 65 detects the protruding piece 66 and outputs a detection signal to the main control unit 100. Here, the cover detection sensor 65 and the protruding piece 66 are installed at opposite positions, and the cover detection sensor 65
The opening cover 63 and the protruding piece 66 may be arranged inside the stamp housing 62.

By closing the open / close cover 63 and holding it in the closed position, the stamp 50 is supported at the drive position shown in FIGS. 2 and 3 through the opening 64, and the original 50 can be printed.

Next, the control operation for the stamp 50 in the automatic document feeding unit of this embodiment will be described. When the user operates the mode switching button 113 of the operation / display unit 110, the main control unit 100 has a print mode in which the stamp 50 executes printing on the document or a non-print mode in which the operation of the stamp 50 is stopped. Either one of the operation modes is set. When the print mode is set, the main control unit 100 causes the reverse drive roller to rotate after a certain time from the timing when the reverse / paper discharge sensor 22 detects the original.
The document is temporarily stopped at the marking position by stopping 20 and a drive signal is output to the stamp 50 during this stop period. The stamp 50 prints an end mark on a predetermined position of the document by inputting a drive signal, and after the printing is completed, the document is started to be conveyed again, inverted, and returned to the reading position again.
Alternatively, the document is discharged to the document discharge unit 31.

At the time of setting the printing mode or the non-printing mode described above, for example, the opening / closing cover 63 is inadvertent due to the carelessness of the user.
May not be completely closed. In such a case, even if the printing mode is set as the operation mode of the apparatus, since the stamp 50 is not supported at the driving position, the stamp 50 cannot print on the document. Further, even when the non-printing mode is set, foreign matter may be inserted into the document conveyance path through the opening 64 and the insertion hole 43, so that the reliability and safety of document conveyance are deteriorated. . In the automatic document feeding unit of the present embodiment, a plurality of programs corresponding to the case where the open / close cover 63 is in the non-closed position are set in advance in the main control unit 100. Is selected by changing the setting position of the DIP switch without the

As described above, according to the first aspect of the present invention.
According to the automatic document feeder described above, the cover position detecting means detects the opening / closing of the open / close cover supported by the printing means and arranged to be openable / closable, so that the printing means is activated by the detection signal from the cover position detecting means. It is possible to cope with the case where the opening / closing cover in which the printing means is arranged is not completely closed by determining whether or not the document is in a printable position.

Further, according to the automatic document feeder of the second aspect, the cover detecting means is provided when the control means sets the print mode and starts the conveyance of the document from the document placing portion by the document conveying means. When it is determined that the open / close cover is in the non-closed position by the detection signal from the printer, the print mode is canceled and the non-print mode is set as the operation mode. Since the print mode is not continued and the document does not stop at the marking position, it is possible to prevent the conveyance time from the start of conveyance to the discharge of paper to be prolonged due to unnecessary stoppage.

Further, according to the automatic document feeder of the third aspect, the control means determines that the print mode is set and the open / close cover is in the non-closed position based on the detection signal from the cover detection means. When the print mode is set, the user can easily confirm that the open / close cover is in the non-closed position before the reading of the original is started by outputting the alarm output signal to the alarm notification means before the reading of the original is started. So, for example,
After recognizing this, the document can be printed by closing the open / close cover.

Further, according to the automatic document feeder of the present invention, when the control means determines that the open / close cover is in the non-closed position based on the detection signal from the cover detection means, By outputting the alarm output signal to the alarm notifying means before the reading of the document is started, the user can easily recognize that the open / close cover is in the non-closed position before the reading of the document starts.
By recognizing this, closing the open / close cover eliminates the risk of accidentally inserting foreign matter into the document transport path because the open / close cover is open, and when setting the print mode It becomes possible to print the stamp on the.

Further, according to the automatic document feeder of the fifth aspect, the control mode sets the print mode as the operation mode when the document transporting means starts transporting the document from the document placing portion. In addition, when it is determined that the open / close cover is in the non-closed position based on the detection signal from the cover detection unit, the start of the document conveyance by the document conveyance unit is prohibited, so that the document is not transferred when the print mode is set. It is possible to prevent the paper feeding operation from starting in a state where the printing operation cannot be performed.

Further, according to the automatic document feeder of the sixth aspect, by detecting the document between the reading position and the marking position by the detection signal from the conveyance detecting means, for example, the printing means performs the printing operation. If it is not possible to execute, it is possible to stop the document that has been read at the upstream position of the marking position.If the printing unit is returned to the printable state, the document will be ejected in a short time. You can make it paper.

Further, according to the automatic document feeder of claim 7, the control means sets the open / close cover to the non-closed position by the detection signal from the cover detection means at the timing when the document is detected by the conveyance detection means. If it is determined that there is, by stopping the document feeding means,
When the open / close cover is in the non-closed position, the document stops at the position of the conveyance detection means, so it is possible to ensure that the document is not damaged by foreign matter or the like inserted into the marking position through the opening where the open / close cover is arranged. It can be prevented.

Further, according to the automatic document feeder of the present invention, the control means sets the print mode at the timing when the document is detected by the conveyance detection means, and detects the detection signal from the cover detection means. When it is determined that the open / close cover is in the non-closed position, by stopping the document feeding means, when setting the print mode,
If the open / close cover is closed before the original is conveyed to the detection position by the conveyance detection, normal printing is performed at the marking position, and if the timing open / close cover is in the non-closed position when the original is conveyed to the detection position. Since the document is stopped at the position of the conveyance detection means, it is possible to reliably prevent the document from being damaged by a foreign substance or the like inserted into the marking position through the opening in which the opening / closing cover is arranged.

Further, according to the automatic document feeder of claim 9, the control means sets the open / close cover to the non-closed position by the detection signal from the cover detection means at the timing when the document is detected by the conveyance detection means. If it is determined that the document is present, an alarm output signal is output to the alarm notifying unit so that the opening / closing cover is closed before the user starts reading the document at the timing when the document stops at the detection position of the conveyance detecting unit. Since it is possible to easily recognize that it is in the closed position, for example, by closing the open / close cover after recognizing this, foreign matter or the like is mistakenly inserted into the document feeding path because the open / close cover is open. It is possible to eliminate the risk that the document will be printed, and when the print mode is set, the printing on the document is executed normally.
