Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flat scanning facsimile device that can repeatedly transmit a plurality of documents by electronic means as many times as desired.

FIG. 1 shows a cassette type flat scanning facsimile transmitter. In this device, multiple sets of cassettes 11 are connected to two sets of pins 12 and 13.
position and set it in the automatic replenishment section 14. In this state, when the operator presses the send button 15, the lowest cassette is fed into the main body of the apparatus, and the image of the original set in this cassette is electronically transmitted. When the electrical transfer is completed, this cassette is ejected onto the ejection tray 16, and the next cassette, which is now located at the lowest stage, is fed into the main body of the apparatus. In this way, the automatic replenishment section 14
All transmission documents for the cassettes 11 set in the cassette 11 are automatically transmitted electronically to the desired destination for each cassette.

By the way, like when sending two identical resident cards from the city hall to a branch office using the city hall facsimile,
There are cases where multiple recording images are required for each original to be sent. About all the submitted manuscripts 2
If the same number of images is required to be recorded, some conventional devices can also make such settings. However, if the required number of recorded images differs depending on the original to be sent,
Conventional devices do not have a way to directly deal with this problem, and the method is to either remove only the cassette of the original to be sent that requires multiple recorded images from the output tray and set it again in the automatic replenishment section, or to record the recorded images on the receiving side. The only way to do this was to make a copy. In the former case, there was a problem in which the automation of transmission by the automatic replenishment unit was impossible, and in the latter case, there was a problem in that copying work was required on the receiving side.

Of course, in a system equipped with a storage/exchange device, it is possible to store the image signal for a transmission document that requires multiple recorded images in the memory of the exchanger, and repeatedly transmit this image signal to the receiving side. . However, such a system has the problem of requiring a large amount of memory in the exchange.

The present invention has been made in view of the above-mentioned circumstances, and it is an object of the present invention to provide a flat scanning facsimile device that can automatically transmit a plurality of documents even when the number of sheets to be transmitted differs from each other.

In the present invention, the sheet number reading means for reading the transmitted document or the number of transmitted sheets specified on the cassette, and the document feeding mechanism that returns the corresponding transmitted document to the document reading section the number of times the transmitted document is subtracted by 1 from the number of scanned sheets are provided in a plane scanning type. The present invention is provided in a facsimile machine to achieve the above-mentioned purpose.

The present invention will be explained in detail with reference to Examples below.

Figure 2 shows cassette 2 in which a transmission document 21 is set.
2 is shown. A rail 23 is arranged at the tip of the cassette 22 in a direction (main scanning direction) perpendicular to the cassette feeding direction (forward scanning direction).
A number designation cursor 24 and a channel selection cursor 25 are slidably attached to this rail. Of these, the sheet number designation cursor 24 is set to a mark corresponding to the specified number of sheets among the sheet number designation marks 26 written on the cassette. The figure shows the position of the number-of-sheets designation cursor 24 when the designated number of sheets is two. Further, the channel selection cursor 25 is set to the mark of the designated destination among the destination designation marks 27 written on the cassette.

FIG. 3 is a diagram for explaining the movement of the cassette after it has been sent into the facsimile transmitter. The cassette placed at the lowest stage of the automatic replenishing section 14 shown in FIG. 1 is placed on the synchro belt 31 at the start of the transmission operation. The synchro belt 31 is an endless belt that is stretched around pulleys 32 to 34, and moves the cassette 22 as the drive pulley 33 rotates.

FIG. 4 shows the drive mechanism of the synchro belt 31. A spur gear 42 attached to the shaft 41 of the pulley 33 is meshed with a spur gear 44 attached to an electromagnetic clutch 43, and the electromagnetic clutch 43 is connected to a pulse motor 46 via a gearbox 45. . Therefore, the synchro belt 31 can change its moving speed and direction by switching the frequency and polarity of the pulses supplied to the pulse motor 46.

Now, the cassette 22 placed on the synchro belt 31 is rapidly fed in the direction of the arrow 35 as the pulse motor 46 rotates relatively quickly. As a result, when the cassette 22 is moved to a position A shown by a solid line in FIG. 3, its leading end is detected by a front end detector 36 consisting of a photocoupler. As shown in FIG. 5, when the front end detector 36 detects the front end of the cassette 22, the front end detection signal generating circuit 51 generates a detection signal. This detection signal is supplied to a detection position memory 53 which receives the clock signal from the clock generator 52, and is stored as the front end detection position. The detection position memory 53 also has a control function to control the electromagnetic clutch 43 and the pulse motor 46 according to the stored contents, and counts the clock signal after detecting the front end of the cassette 22, and when the clock signal reaches a predetermined value. The electromagnetic clutch 43 is released.

At this point, the cassette 22 is in position B, indicated by the dotted line in FIG. At this position B, the tip of the cassette 22 is illuminated by the fluorescent lamp 37, and the position of the sheet number designation cursor 24 (Fig. 2) is set to CCD (Charge).
The information is read by an optical section 38 consisting of a Coupled Device. The read information is sent to the preamplifier 54
After being amplified by the repetition number detection circuit 55
sent to.

The repetition number detection circuit 55 converts the period T (FIG. 6a) during which the image signal is sent into phase signals 61 and 62.
(Fig. 6b). Then, the number of repeated sheets is detected based on the position of the sheet number designation signal 63 (shown in the figure) existing between both phase signals 61 and 62. The repetition number detection signal obtained in this manner is supplied to the repetition number memory 56 and stored therein until all transmission operations for this cassette are completed.

After the number of repeated sheets has been read in this manner, the detection position memory 53 brings the electromagnetic clutch 43 into the direct connection state and causes the pulse motor 46 to perform forward rotation at the normal rotation speed. Through this steady feeding operation, image information on the original 21 (FIG. 2) is read by the optical section 38. The image signal output from the optical section 38 is amplified by the preamplifier 54 and then transmitted to the receiving side via a signal processing section and a modulation/demodulation circuit (not shown).

When scanning of the original is completed and the cassette 22 moves to position C shown in FIG. 3, a rear end detector 39 consisting of a photocoupler detects the rear end of the cassette 22.
Based on this, the trailing edge detection signal creation circuit 57 creates a detection signal and supplies it to the detection position memory 53. The detection position memory 53 stores this as the rear end detection position.

FIG. 7 shows the state of movement of the cassette when the number of sheets to be transmitted is set to two. Position A
The cassette that has been moved from to position C and has finished transmitting the first cassette is returned to position A. Therefore, the detection position memory 53 causes the pulse motor 46 to rotate in reverse. After returning to position A, the same operation as described above is performed and the second sheet is transmitted. When the second transmission is completed, the repetition memory 56 receives the clock signal from the clock generator 52.
sends a control signal to the detected position memory 53. Based on this, the detected position memory 53 causes the pulse motor 46 to rotate normally at a relatively fast speed. As a result, the cassette 22 is rapidly forwarded in the direction of the arrow 35, separated from the synchro belt 31, and discharged onto the discharge tray 16 (FIG. 1).

As described above, according to the present invention, by simply performing simple operations such as setting the cursor on the cassette or marking a predetermined part of the document, it is possible to automatically and continuously transmit documents in the document to be sent. Some manuscripts can be sent twice or more times. Moreover, since the facsimile transmission device does not require a large capacity memory for one screen, the device can be manufactured at low cost.
