Description: TECHNICAL FIELD The present invention relates to a facsimile machine.

Conventionally, as shown in FIG. 3, this type of facsimile apparatus has a document presence / absence detection sensor 9 for detecting the presence / absence of a document along a document conveyance path indicated by an arrow direction in the figure, and one document at a time. Separation rubber 1 and a paper feed roller 2 that takes in the original, a feed roller 3 that conveys the original taken in by the paper feed roller 2 at a predetermined speed, and a reading position detection for detecting the reading position of the original image. Sensor 10,
Read the image of the document conveyed by the feed roller 3,
An optical system 4 for transmitting an image signal to a facsimile machine on the receiving side through an electric system (not shown), a transmitted stamp 5 for imprinting a stamp indicating the end of transmission on a document, and a document after image reading is ejected. A discharge roller 6 is arranged for this purpose.

A coaxial drive gear 2a and drive pulleys 3a and 6a are attached to the paper feed roller 2, the feed roller 3 and the discharge roller 6, respectively, and drive pulleys 3a and 6a of the feed roller 3 and the discharge roller 6 are attached.
Are connected to the shaft of the drive motor 7.

The feed roller 3 is also provided with a transmission gear 8a of a clutch mechanism 8 for transmitting the power of the motor 7 to the paper feed roller 2.

The transmission gear 8a of the clutch mechanism 8 is rotatably attached to the center of a substantially L-shaped clutch arm 8b, and one end of the clutch arm 8b meshes with the transmission gear 8a and feed roller 2 is provided. An intermediate gear 8c that can be engaged with the drive gear 2a is rotatably attached, and one end of a spring 8d that is biased to separate the drive gear 2a and the intermediate gear 8c from each other is attached to the other end.

The other end of the spring 8d is attached to the main body side (not shown) of this facsimile machine, and the other end of the clutch arm 8b meshes the drive gear 2a and the intermediate gear 8c against the bias of the spring 8d. In order to be connected to the iron core of the solenoid 8d.

The sensors 9 and 10, the reading optical system 4, the drive unit of the transmitted stamp 5, the motor 7, and the coil of the solenoid 8d are connected to an electric system (not shown).

In the above configuration, when the document presence / absence detection sensor 9 detects the leading edge of the document, the electric system rotates the motor 7 and operates the solenoid 8d of the clutch mechanism 8, and thus the power of the motor 7 is transmitted to the sheet feeding roller 2 Starts capturing the original.

Then, when the reading position detection sensor 10 detects the reading position of the original image, the optical system 4 starts reading the original image, the electric system transmits the data of the original image to the receiving side facsimile apparatus, and the leading edge of the original is read. When the sheet reaches the discharge roller 6, the discharge roller 5 starts discharging the document.

In this step, if the document presence detection sensor 9 or the reading position detection sensor 10 does not detect the next document, the electric system sends an EOP signal indicating the end of the procedure to CCITT.T30 to the receiving facsimile machine. On the other hand, when the next original is detected, the EOM signal indicating the end of the message is transmitted to the receiving side facsimile apparatus.

When an MCF signal indicating receipt confirmation is received from the receiving facsimile machine in response to the EOP signal or the EOM signal, the transmitted stamp 5 is driven to imprint the original document, and the ejection roller 6 ejects the original document. To do.

Here, the next document is an OMR (Optical Mark) in which data such as the destination, transmission mode, and light and shade of the document is optically written.
If the sheet is a Reading sheet, the data of the OMR sheet is read by the optical system 4 or a dedicated sensor, and the procedure for the EOP receiving side facsimile apparatus is performed from phase A after transmitting the previous document image.

In this case as well, when the OMR sheet is detected, the EOP signal for the previous document is transmitted, and when the MCF signal from the receiving side facsimile device is received in response to the EOP signal,
The sent stamp 5 is imprinted on the previous document and is ejected by the ejection roller 6.

However, in the above-mentioned conventional facsimile apparatus, the presence or absence of the next original and the presence of the OMR sheet in order to imprint the transmitted stamp on the previous original after detecting the presence or absence of the next original or the OMR sheet. The previous document cannot be ejected until
Therefore, there are problems that the document transport path becomes long, the document jams increase, and the apparatus becomes large.

Further, when the paper feed roller 2 and the next original slip, the next original does not reach the detection position even if the previous original reaches the position of the transmitted stamp, and a dedicated sensor for detecting the OMR sheet. However, there is a problem in that it is expensive.

In view of the above problems, the present invention shortens the document transport path,
Another object of the present invention is to provide an inexpensive facsimile machine.

Means for Solving the Problems In order to solve the above problems, the present invention provides a clutch mechanism for selectively transmitting the power of a motor for driving a feed roller to a paper feed roller or a discharge roller, so that the leading edge of a document is If detected, drive the motor to drive the feed roller and control the clutch mechanism to drive the paper feed roller to capture the original and control the clutch mechanism when the leading edge of the original reaches the discharge roller. Drive the eject roller to start ejecting the document, and when the trailing edge of the document is detected, the clutch mechanism is controlled to drive the paper feed roller, and after receiving the MCF signal from the receiving facsimile machine, it is transmitted. Is stamped on the original, and the discharge roller is driven by controlling the clutch mechanism to discharge the original.

With the above configuration, when the rear end of the previous document is detected, the clutch mechanism switches the power of the motor from the discharge roller to the paper feed roller to stop the previous document.
Also, the paper feed roller is set in a state in which the next original can be taken in. A stamp indicating that the next original has been sent and the original that has stopped after detecting the presence or absence of the OCR sheet has been stamped, and the clutch mechanism switches the power of the motor from the paper feed roller to the discharge roller Let it drain.

Is engaged with the drive gear 2a of the paper feed roller 2 and the intermediate gear 80d is separated from the drive gear 6b of the discharge roller 6.

Therefore, the document is stopped at the position of the discharge roller 6 and is not discharged to the outside of the apparatus, and the paper feed roller 1 is ready to take in the next document.

Next, when the document presence detection sensor 9 or the reading position detection sensor 10 does not detect the next document, the electrical system is CC
An EOP signal indicating the end of the procedure as shown in ITT.T30 is transmitted to the receiving side facsimile apparatus, while when the next original is detected, an EOM signal indicating the end of the message is transmitted to the receiving side facsimile apparatus.

Then, when an MCF signal indicating reception confirmation is received from the receiving-side facsimile device in response to the EOP signal or the EOM signal, the transmitted stamp 5 is driven to imprint the previous document, and the clutch mechanism 80 is set to the second position. Switching is performed as shown in FIG. 6B, and the discharge roller 6 discharges the original.

Next, when the next original is not detected, the motor 7 is stopped to end the predetermined transmission procedure (phase E), while
When the next original is detected, the clutch mechanism 80 is switched as shown in FIG. 2 (a) and similar image data is transmitted.

Here, the next document is an OMR (Optical Mark) in which data such as the destination, transmission mode, and light and shade of the document is optically written.
If the sheet is a Reading sheet, the optical system 4 reads the data on the OMR sheet, sends the EOP signal after sending the previous document image (Phase C), and receives the MCF signal from the receiving facsimile machine (Phase D). Then, the transmitted stamp 5 is driven to imprint the previous document, and the clutch mechanism 80
2 is switched as shown in FIG. 2B, the document is discharged by the discharge roller 6, and the procedure of the phase E is completed.

Therefore, in the above embodiment, the presence or absence of the next document and the OMR
Since the conveyance of the previous document is stopped until the sheet is detected, the document conveyance path can be shortened, and it is possible to prevent the document jamming and the enlargement of the apparatus.

Further, even if the paper feed roller 2 and the next original slip, the next original can be reliably detected because the previous original is stopped, and the optical system 4 for reading the original image allows the OMR to be detected. In order to be able to read the data on the sheet,
A dedicated sensor is not required and an inexpensive facsimile machine can be realized.

In the above embodiment, the paper feed roller 2 and the discharge roller 6
Power is transmitted to the feed roller 3 through the feed roller 3, but the clutch mechanism 80 is directly connected to the output shaft of the motor 7, and the power of the motor 7 is selectively transmitted from the clutch mechanism 80 to the paper feed roller 3 or the discharge roller 3. Of course, it may be transmitted to the roller 6.

As described above, according to the present invention, the clutch mechanism that selectively transmits the power of the motor that drives the feed roller to the paper feed roller or the discharge roller is provided, and the motor is driven when the leading edge of the document is detected. Drive the paper feed roller and control the clutch mechanism to drive the paper feed roller to capture the original, and when the leading edge of the original reaches the discharge roller, the clutch mechanism is controlled to drive the discharge roller. When the rear end of the document is detected, the paper feed roller is driven by controlling the clutch mechanism, and after receiving the MCF signal from the receiving facsimile machine, a stamp indicating that the document has been sent is printed on the document. Since the original is ejected by driving the ejection roller by imprinting and controlling the clutch mechanism, the original conveyance path is short and the sheet is inexpensive. It is possible to realize an accumulator device.
