Abstract

PURPOSE:To reduce incurring of a loss time, by a method wherein only an original discharge roller is stopped to hold an original until yes response is received from a mating part, during the stop, a separation roller and a reading part feed roller are moved, and the original of a next page is conveyed to the vicinity of a reading position. CONSTITUTION:A roller R1 and a separation roller 2 are driven to feed one original. When it is detected that the original arrives, a separation roller 2 is stopped, and a roller R2 is driven. Reading transmittance is started. When the rear end of the original passes a sensor S2, reading is completed, and the roller R2 is stopped. When a sensor S1 is in an ON-state, the separation roller 2 is driven, a next page is fed to a reading part by means of the roller R1. When, during the feed to the reading part, yes response from mating part is received, transfer to processing of a next page is effected. When the sensor S1 is brought into an OFF-state, since there is no subsequent page, while yes response from mating part is waited, the original is discharged, the roller R1 and R2 are stopped, and whole action is completed. This constitution enables reduction of incurring of loss time.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile machine having a document conveying/reading section that efficiently conveys multi-page documents.

(Prior Art) Fig. 5 shows the configuration of a document conveyance/reading section in a general facsimile machine, and Figs. 6 and 7 are time charts showing operations according to the conventional technology when there is no sent stamp and when there is a sent stamp, respectively. It is.

Multi-page originals set on the original table 1 are taken out one by one by a separating unit consisting of a separating roller 2 and a separating rubber 3, and are read by an original feeding roller R1 using a light beam R4 and a reader 5. It is sent to the position of the section, read and transmitted by the reading section, and is also sent to the ejecting roller R.
2, and the next page of the original is fed to the reading unit. The feeding roller R1 and the discharging roller R2 are coupled to a driving motor 6 via a timing belt 9. Furthermore, the separation roller 2 is coupled to the roller R1 via an electromagnetic clutch 7 and a timing belt 8. A sent stamp device is provided between the reading section and roller R2.

In an apparatus having such a configuration, when transmitting a multi-page original, the next page is sent after the trailing edge of the previous page passes through the original sensor S2 of the reading unit. That is, the rear end of the previous page and the leading edge of the next page are separated by the same distance as the distance between the document sensor S1 of the paper separating section and the document sensor S2 of the reading section.

Therefore, after reading the previous page and before starting to read the next page, the previous page must be ejected from the reading section and the next page of original must be sent to the reading section by that distance.

However, in the normal case (no sent stamp), such document feeding does not pose much of a problem. This is because after reading the previous page, you have to wait for an acknowledgment from the MCF etc. that the reception of the first page has been completed before you can start reading the next page. This is because it can be sent to the reading position (or near the reading position). In this case, there is some loss time, but the amount of loss is small. FIG. 6 shows the timing of the operation. As shown in FIG. 6, when the sensor 51 detects that there is a document in the separating section, if the start button (I2I not shown) is pressed, the rollers R1 and R2 are driven and the electromagnetic clutch 7 is activated. The separating roller 2 operates for a certain period of time, and one document is fed to the reading section by the roller R1. When the document comes to the reading section, the sensor s
2, and reading and transmission will begin immediately. When the reading progresses and the rear end of the document passes the sensor S2, the electromagnetic clutch 7 is energized, the separation roller 2 is operated, and feeding of the next page of the document is started. Since a sent stamp is not stamped, feeding of the next page can be started immediately, and loss time is relatively small.

However, when using the sent stamp mode, it is necessary to wait for an acknowledgment from the MCF etc. before stamping the sent stamp, so while waiting for the acknowledgment, the document feed is stopped and the original is not placed in the eject mode. It must be held on roller R2. When an acknowledgment signal is received and a sent stamp is stamped, the sent original is ejected by roller R2 and feeding of the next page of the original begins, saving extra time for feeding the distance between the originals. I end up needing it. FIG. 7 shows the timing of the operation. As shown in FIG. 7, when the reading and sending of one page is completed, the rollers R1 and R2 are stopped, and after a sent stamp is stamped in response to a positive response, the rollers R1 and R2 and the separating roller 2 are operated. Therefore, it takes more time than in the case of FIG. 6 from the end of reading and sending to the time when the sent stamp is affixed.

Due to this loss time, the transmission time when transmitting a multi-page manuscript becomes longer, and the longer the transmission time, the higher the call charge, which is a problem.

(Problems to be Solved by the Invention) If the loss time in the above-mentioned conventional technology can be eliminated (or reduced), it becomes possible to shorten transmission time and reduce call charges.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to solve the above-mentioned problem in the conventional facsimile machine, in which a lot of lost time occurs during a call due to the gap between documents when transmitting multiple pages, especially when stamping a sent stamp. It's about doing. That is, it is an object of the present invention to provide a facsimile apparatus that can reduce call charges by reducing the time gap between documents and reducing loss time.

(Structure of the Invention) In order to achieve the above object, the present invention includes a separation roller for taking out a plurality of transmission originals one by one, a first roller for feeding the original from the separation roller to a reading section, and In a facsimile machine that has a document transport unit equipped with a second roller that ejects the document from the reading unit, the second The rollers are stopped and the second roller holds the original that has been read and sent, and while the 20th roller is holding the original that has been read and sent, the separating roller and the first roller The apparatus is characterized in that it has means for driving the next document to feed the next document to the reading section.

(Function) In the present invention, only the second roller is stopped to hold the document until a signal such as the MCF is received, and during that time, the separating roller and the first roller are moved to move the document to the next page. The next page can be read and sent immediately after receiving an acknowledgment from the MCF etc. and stamping the sent stamp, reducing the loss time that was a problem when using multiple pages. be able to.

(Example) An example of the present invention will be described. In this example, the fifth
In the configuration shown in the figure, only roller R2 is stopped and the document is held until a signal such as MCF is received.
Meanwhile, separation roller 2. It is configured to move the roller R1 and feed the next page of the document to the vicinity of the reading position.

FIG. 1 shows an embodiment of a drive device for this purpose, and shows an embodiment using a one-way clutch and forward and reverse rotation of a motor. The discharge roller R2 is driven in the normal direction, and the separation roller 2 is driven in the reverse direction. Gears +1, 12, 13, 14 driven by motor 6 and connected as shown in Figure 1
．． +5.16.17.18, a one-way latch that connects the gear 13 and the shaft of the roller R1 and locks it during normal rotation! 9, a one-sided clutch 20 that connects the gear 15 and the shaft of the roller R2 and locks it during forward rotation, and a one-sided clutch 21 that connects the gear 16 and the shaft of the separation roller 2 and locks it during reverse rotation.
It consists of a one-sided clutch 22 that connects the separation roller 2 and its shaft and locks it during reverse rotation.

When the motor 6 rotates normally, the one-way clutches 19 and 20 are locked, so the rollers R1 and R2 are driven. At this time, the separation roller 2 is stopped because the one-sided clutch 22 is unlocked, but is rotated by the document.

When the motor 6 is reversed, the one-way clutches 21 and 22 are locked, so the separation roller 2 and the roller R1 are driven, but the one-way clutches 19 and 20 are not locked, so the roller R2 is stopped.

The operation of this embodiment using such a drive mechanism will be explained with reference to the time chart of FIG. 3 and the operation flow chart of FIG. 4.

When the start button is pressed while the sensor St is on, the roller R1 and the separation roller 2 are driven, and one document is fed. When the arrival of a document is detected and the sensor S2 is turned on, the separation roller 2 is stopped and the roller R2 is driven. Then, reading and transmitting is started. When the reading and transmitting progress and the rear end of the document passes the sensor S2 and the sensor S2 is turned off, the reading is completed and the roller R2 is stopped.

Next, it is checked whether the sensor S1 is on, and if it is on, it is not the last page and there is a subsequent page, so the separating roller 2 is driven and the next page is fed to the reading section by the roller R1. . If there is an acknowledgment from the other party during this time, a sent stamp is stamped on the previous page of the document depending on whether the mode is for stamping a sent stamp. Then, the process moves to the next page.

In checking whether the sensor Sl is on or not, if the sensor Sl is off, it is the last page and there is no subsequent page, so wait for an acknowledgment from the other party.
After pressing the sent stamp, the document is ejected, rollers R1 and R2 are stopped, and the entire operation is completed.

As is clear from comparing the timing chart of this embodiment shown in FIG. 3 with the conventional timing chart shown in FIG.
In this embodiment, the paper feeding roller R1 is driven all the time, and only the ejecting roller R2 is stopped to wait for an affirmative response, so the next document can be fed to the reading unit during the waiting period. Therefore, it is possible to read and send the next page immediately after receiving an acknowledgment from the MCF or the like and stamping the sent stamp, thereby reducing loss time, which is a problem when using multiple pages.

Note that by driving the separation roller 2 and the rollers R1 and R2 using a one-way clutch as in this embodiment, there is no need to use an expensive electromagnetic clutch, resulting in cost reduction.

FIG. 2 shows another embodiment of the drive device, in which the motor 6
Pulleys 25, 26, 27, etc. and timing bells are used to transmit power between the rollers 2, rollers R1, R2, etc., and timing bells) 30.
31. Using 32, separate roller 2. The driving of the feeding roller R2 is controlled by an electromagnetic clutch 33.3'4 or the like.

(Effects of the Invention) As is clear from the above description, the present invention can have the following effects.

(1) Loss time due to the time gap between the previous page and the next page of the document can be reduced, and therefore call charges can be reduced.

(2) By driving the motor in forward and reverse directions using a one-way clutch, there is no need to use an expensive electromagnetic clutch, resulting in cost reduction.
