Description

The present invention relates to an apparatus for enclosing a recording paper document received by facsimile in order to keep confidentiality.

(B) Prior Art An apparatus for enclosing a facsimile reception document and handling it as a confidential document is conventionally known.

For example, Japanese Patent Application Laid-Open No. 63-67062 discloses that a confidential document is distinguished from other documents by reading the identification pattern displayed at the beginning of the received document and the transport path is switched, so that the confidential document is stored in the prepared envelope. It is designed to be automatically enclosed.

Japanese Patent Application Laid-Open No. 58-142664 discloses a method in which a confidential document is superimposed and pasted as it is, so that a received text can be enclosed so as not to go outside.

(C) Problems to be Solved by the Invention In the facsimile recording paper enclosing apparatus described above, even if the length of the recording paper at the time of reception is different, it is conventionally assumed that all the recording papers have the same length, and the folding is performed. I went. However, when a short recording sheet is folded in the same manner, both ends of the folded recording sheet in the longitudinal direction are largely displaced, and the recording sheet is conveyed in a state of a displaced folded sheet having a short upper side surface.

Then, when the next received recording paper is folded and conveyed on the recording paper in the state of the shifted folded paper, it is hooked on the folded upper end of the previously conveyed recording paper, This causes a problem that the sheet is not reliably stacked on the envelope paper.

Also, if recording paper longer than the specified length is sent from the transmitting side, the recording paper is too long, and even if the leading end is stopped and bent with a predetermined stopper, it cannot be stacked with envelope paper. There was a problem that the encapsulation became impossible.

The present invention is configured to detect a sheet exceeding the specified length and to stop the folding / sealing operation.

Also, when the folded recording paper is placed on the recording paper tray by the folding guide roller and stacked with the envelope paper, if the leading edge of the folded recording paper is rolled up, the smooth In order to prevent the recording paper from being rolled up, the recording paper holder is hung down.

(D) Means for Solving the Problems The problems to be solved by the present invention are as described above. Next, means for solving the problems will be described.

A means for taking in the recording paper discharged from the facsimile receiver, and a first means for folding and folding the taken-in recording paper into two parts
Folding means, a second folding means for simultaneously folding the recording paper and the envelope paper in a state where the two-folded recording paper is laminated on the envelope paper, and bonding the end portions of the envelope paper to each other. In a configuration having an enclosing means for enclosing the recording paper, an intermediate length stopper is provided between the folding guide roller and the maximum paper length stopper, and a recording paper length sensor for detecting the recording paper length is provided. A means for driving the intermediate length stopper in accordance with a signal from the sensor is provided.

In addition, the recording paper length sensor and the intermediate length stopper are arranged so that, when the recording paper B is folded and disposed on the recording paper tray, the upper folding side is longer than the lower folding side. Things.

Further, between the recording paper take-in mechanism and the first folding means, a specified length excess sensor 5 for detecting that the recording paper is longer than a specified length is provided. When the recording paper is detected, the sealing device is stopped.

Further, a recording sheet press is arranged at a position above the recording sheet sent out from the exit side of the folding guide roller onto the receiving tray.

(E) Embodiment The problems to be solved and means to be solved by the present invention are as described above. Next, the configuration of the embodiment shown in the attached drawings will be described.

FIG. 1 is a side sectional view showing a state in which a facsimile apparatus F is arranged on a facsimile recording paper enclosing apparatus A,
The facsimile machine F is generally commercially available, and the recording paper received by the facsimile machine F is inserted from the recording paper entrance 15. In the case of a document that requires enclosing, the format of the outgoing document is determined separately, and a recognition pattern that specifies that it is a confidential document that requires enclosing is placed in the first predetermined place of the outgoing document. Have been described.

The recognition pattern is detected by a recognition sensor 43 (reflection type optical sensor) provided immediately after the recording paper entrance 15, and in the case of a confidential document that needs to be enclosed, two upper and lower guide rollers 17 are used.
The recording paper B is taken into the enclosing device by switching the switching gate 9 disposed at a position between 17, 16, and 16.

The recording paper B whose course has been changed in the direction of the enclosing device by the switching gate 9 descends between the fixed guide plates 35 and 36 and is conveyed between the upper conveying belt 11 and the lower conveying belt 12.

A sensor 5 exceeding the specified length is arranged in a part of the fixed guide plate 35, and a recording paper input sensor 4 (transmission type optical sensor) is arranged.

A recording paper length sensor 3 (transmission type optical sensor) is disposed near the lower ends of the fixed guide plates 35 and 36. The recording paper length sensors 1 and 2 ( Transmission type optical sensor).

The recording paper B is conveyed while being placed on the lower conveying belt 12, and the upper conveying belt 11 is gradually moved to the lower conveying belt 12.
It is configured to go close to.

In the portion of the folding guide roller 24 for driving the lower end of the upper conveying belt 11 and the folding guide roller 23 for driving the lower end of the lower conveying belt 12, the two rollers come into contact with each other and pinch the recording paper B. It is configured to

The folding roller 25 is brought into contact with the folding guide roller 23 and
Is arranged.

Stopper guide plates 30 and 31 into which the leading end of the recording paper B which is sent out while being sandwiched between the folding guide rollers 23 and 24 are vertically arranged in parallel.

The stopper guide plate 30 arranged in parallel with the upper and lower sides
The intermediate length stoppers 6 and 7 and the maximum sheet length stopper 8 that protrude are provided between 31.

While the maximum paper length stopper 8 is always fixed on the protruding side, the intermediate length stoppers 6 and 7 are supported by solenoids S1 and S2 so as to be freely protruded and stored.

The leading end of the recording paper B is pushed out by the folding guide rollers 23 and 24 and enters the stopper guide plates 30 and 31. However, when the leading end contacts the stopper, further intrusion is prevented and the folding is performed. The bending starts at the position where the bending guide rollers 23 and 24 have come out, and the bent portion is the bending guide roller 23 and the bending roller.
25, the sheet is folded in a double-fold state, and the folded sheet is supplied onto the recording paper tray.

The first bent portion of the present invention includes the bent guide roller 23, the bent roller 25, and the stopper guide plates 30 and 31.

On the recording paper tray 34, in order to sufficiently stack the folded recording paper B, a recording paper holder 29 suspended from above is used.
28 and a non-slip 32 stuck on the upper surface of the recording paper tray 34
Is arranged.

Further, the envelope paper C is supplied from the outside of the enclosing device A along the envelope paper guide plate 39, and is fixed by the tractor feeder 38 in a state where the transport pins are inserted into the forced feed holes in the ears of the envelope paper C. It is sent exactly by length.

Then, the envelope paper C that has exited the tractor feeder 38 passes through the envelope paper feed roller 14 provided with the electromagnetic brake device 47, and from the envelope paper guide plate 33 above the enclosed folding rollers 20 and 21 and the ear pressing roller 22. To reach the envelope paper guide plate 48 on which the envelope paper standby sensor 37 is disposed.

Then, when the folding of the recording paper of a series of documents detected by the recognition sensor 43 is completed, the folding blade 18 is pushed down, and the envelope paper C is inserted between the enclosed folding rollers 20 and 21.
And the recording paper B are folded.

The second bent portion of the present invention is constituted by the folding blade 18 and the enclosed bending rollers 20 and 21.

As shown in FIG. 13, the folding blade 18 is moved up and down by an eccentric cam wheel 46, and the top dead center and the bottom dead center of the folding blade 18 are eccentric cams which rotate integrally with the eccentric cam wheel 46. It is detected by the folding blade position sensors 44 and 45 fixedly arranged along the shaft outer periphery 58, respectively.

Folded roller folded by folding blade 18
The envelope paper C and the recording paper B enclosed by 20 and 21 fall along the discharge guide plate 49.

The first drive motor M1 drives the folding guide rollers 23 and 24 and the folding roller 25, and further drives the eccentric cam wheel 46 of the folding blade 18 moving up and down.

The rotation direction of the bending guide rollers 23 and 24 and the eccentric cam ring
The direction of rotation of the eccentric cam wheel 46 is set to the opposite direction, and the one-way clutch 51 is interposed in the drive unit of the eccentric cam wheel 46, so that the recording paper B is conveyed by the folding guide rollers 23 and 24. Are configured so that the eccentric cam wheel 46 does not rotate. Conversely, when the eccentric cam wheel 46 rotates, the folding guide rollers 23 and 24 rotate as they are, but in this case, the recording paper B is not sandwiched, so there is no effect.

Further, the second drive motor M2 is configured to perform forward and reverse rotation, drive the envelope sheet feeding roller 14 and the tractor feeder 38 by one rotation, and drive the enclosing folding rollers 20 and 21 by reverse rotation. I have. A one-way clutch 50 is interposed in the drive unit of the enclosing folding roller 20, so that the enclosing folding rollers 20 and 21 do not rotate when the envelope paper feeding roller 14 and the tractor feeder 38 are driven. Make up.

When the enclosing folding rollers 20 and 21 rotate to pull the envelope paper C in order to simultaneously fold and enclose the stacked envelope paper C and recording paper B, the envelope paper feeding roller 14
Is braked by an electromagnetic brake device 47, and as the envelope paper C is stretched as it is, the buster blade 13 which faces downward and cuts into the perforation, encloses with the envelope paper feeding rollers 14, 14. Since the envelope paper C is disposed between the curved rollers 20 and 21, the envelope paper C is cut from the perforated portion of the envelope paper C just below the buster blade 13.

In FIG. 2, the configuration and operation of the specified length excess sensor 5 will be described.

The specified length excess sensor 5 is arranged at a position between the guide rollers 17 and the bending guide rollers 23 and 24, and the transport speed is configured to be higher than the recording paper sending speed from the facsimile apparatus F. .

Therefore, in the case of a recording paper exceeding the specified length which is long enough that the leading end of the recording paper B is also sandwiched between the bent guide rollers 23 and 24,
The recording paper B is stretched until it is pushed between the facsimile machine F and the folding guide rollers 23 and 24 so that the sensor 5 presses the specified length excess sensor 5.

As a result, when the specified length excess sensor 5 is turned on, the twelfth
The control flowchart operates as shown in the figure.

That is, when the specified length excess sensor 5 is turned on, it performs error processing.

It is desirable that the processing of this error implements one of the following.

. When it is detected (ON) that the recording paper B is longer than the specified length by the specified length sensor 5, the first drive motor M1 is temporarily stopped and then the specified length sensor 5 is turned off again.
If F is performed, the first drive motor M1 is rotated so that the recording paper B is carried in.

By repeatedly performing the ON-OFF control, the folding guide rollers 23 and 24 and the recording paper sending roller 11 in the facsimile apparatus F can be controlled.
The recording paper B can be fed into the enclosing device A without causing excessive tension due to the difference in the peripheral speed of 2, but the recording paper B outside the specified length is deposited in the enclosing device A in a state where it cannot be encapsulated. Thereafter, in the main routine (FIG. 20), the enclosing operation is not performed due to the occurrence of an error.

. Further, the cutter 110 shown in FIG. 2 is operated at the stage when the specified length excess sensor 5 is turned on, so that the fed recording paper B is cut into a length that can be inserted and enclosed.

In this way, the enclosing apparatus A can continue to take in the recording paper B thereafter, so that it is not necessary to prohibit the subsequent enclosing and enclosing operation by the above-described error processing, and automatic continuous reception becomes possible.

The folding of the intermediate-length paper will be described with reference to FIGS.

As shown in the control flowchart of FIG. 11, first, it is checked by the recording paper input sensor 4 whether the end of the recording paper B is completed. Then, when the OFF state of the recording paper input sensor 4 that the end of the recording paper B does not exist in the portion of the recording paper input sensor 4, next, it is determined how far the leading end of the recording paper B reaches the recording paper length sensor 1. Detect by 2/3.

When the recording paper length sensor 1 is ON,
Since the leading end of the recording paper B reaches the portion of the recording paper length sensor 1, the recording paper length is about B4, which is the longest in the embodiment. In this case, the leading end of the recording paper B is the maximum paper length. Since it is necessary to reach the stopper 8, the solenoids S1 and S2 are not turned on, and the intermediate length stoppers 6 and 7 do not project.

Next, the recording paper length sensor 1 is turned off and the recording paper length sensor 2 is turned on.
In this case, since the recording paper length is about A4 in the embodiment, it is necessary to protrude the intermediate length stopper 7 and stop it at this position, and turn on the solenoid S2.

Next, when the recording paper length sensors 1 and 2 are both OFF and the recording paper length sensor 3 is ON, the intermediate length stopper 6 needs to be protruded since the embodiment has the shortest length of B5. Yes, the solenoid S1 is turned ON.

When the recording paper input sensor 4 is OFF and none of the recording paper length sensors 1, 2, and 3 is ON, the recording paper B has a length equal to or less than the specified length. Display and stop the enclosing device.

Next, the recording paper retainers 28 and 29 and the non-slip 32 will be described with reference to FIGS.

As in the present invention, the recording paper length sensors 1, 2, and 3 are provided,
Since the bending position was changed according to the length of the recording paper B, it is necessary to set the upper folding part to be always longer than the lower folding part when one recording paper B is folded. -ing

Since the upper side is longer as described above, as shown in FIG. 6, when the next folded recording paper B is slid and stacked on the previously folded recording paper B, a portion to be caught is formed. Is lost.

Nevertheless, there is a tendency of the folded recording paper B to be curled at the leading end, and as shown in FIG. 5, the recording paper B may rise below the folding blade 18 without passing under the folding blade 18. Therefore, in order to eliminate such inconveniences,
Is hanging down.

As shown in FIG. 6, the next folded recording paper B is placed on the folded recording paper B previously placed on the recording paper tray 34.
, The recording paper B in the floating state is simultaneously pushed and moved forward, so that the address writing portion of the recording paper B is displaced from the address window portion of the envelope paper C or the envelope paper disposed below. It may move to a position outside the width of C.

In order to prevent such a movement of the recording paper B, a non-slip 32 is provided on the upper surface of the recording paper tray 34 to prevent the first folded recording paper B from sliding freely. Then, a recording paper retainer 29 is provided above the non-slip 32 so as to urge the first folded recording paper B in a direction in which it comes into contact with the non-slip 32.

2 and 4, a delivery spring 52 protrudes from the upper end of the recording paper tray 34. The delivery spring 52 fits into a groove 23a provided in the folding guide roller 23. doing.

By providing the delivery spring 52 in this manner, despite being once delivered by the bending guide rollers 23 and 25,
If the folding guide rollers 23 and 25 are rotated counterclockwise by the first drive motor M1 during the folding operation by the folding blade 18 if they remain near the folding guide rollers 23 and 25, the folding is performed again. It is possible to solve the problem that the music guide rollers 23 and 25 bite and are damaged.

FIG. 3 shows a state in which the trailing end of the recording paper B remains near the bending guide rollers 23 and 25 when the delivery spring 52 is not provided.

 FIG. 10 is a perspective view of the envelope paper C in an enclosed state.

A glue portion 121 is provided on the outer peripheral edge of the envelope paper C shown in FIG. 10, and the envelope paper C is pressed by the enclosed folding rollers 20 and 21 and the ear pressing roller 22.

(F) Effects of the Invention The present invention is configured as described above, and has the following effects.

An intermediate length stopper is provided between the folding guide roller and the maximum paper length stopper, and a recording paper length sensor for detecting the recording paper length is provided, and a signal from the recording paper length sensor is provided. Therefore, even if the lengths of the received recording papers B are different from each other, the recording papers B are conveyed after the recording papers B because the recording papers B are bent at a position near the center even if the lengths of the recording papers B differ from each other. The upper bent portion, which is a portion of the recording paper tray 34, can always be longer.
The folded recording paper B inserted into the recording paper no longer gets caught on the previous folded recording paper.

When the recording paper length sensor and the intermediate length stopper are arranged as in claim (2), and the recording paper B is disposed on the recording paper tray in a folded state, the upper side of the folding is lower than the lower side of the folding. When the recording paper B in the folded state is placed on the recording paper tray 34 and the next recording paper B in the next folded state is placed on the recording paper tray 34 while sliding, Since the upper side is long, there is no portion to be caught, and it can slide smoothly and create a laminated state.

As in claim (3), between the recording paper take-in mechanism and the first folding means, a specified length excess sensor 5 for detecting that the recording paper is longer than a specified length is provided. When the sensor 5 detects the recording paper exceeding the specified length, the enclosing device is stopped. Therefore, the recording paper B longer than the encapsulable length is taken into the apparatus, and the facsimile apparatus F records the recording paper. It is sandwiched between both the paper sending roller 112 and the folding guide rollers 23 and 24, so that the recording paper sending roller 112 on the facsimile machine F side and the folding guide rollers 23 and 24 cannot be grasped because of tearing. This eliminates the problem that the overload occurs and the facsimile apparatus F and the enclosing apparatus A are damaged.

According to the fourth aspect of the present invention, since the recording paper holding member is disposed at a position above the recording paper sent out from the exit side of the folding guide roller onto the receiving tray, the address written on the first folding recording paper B is set. This eliminates the problem that the written portion is shifted from the address window portion of the envelope paper C, and it becomes unknown where the document is to be sent after the envelope is enclosed.

In addition, the leading end of the folded recording paper B does not pass below the folding blade 18 but rises along the folding blade 18, and the later folded recording paper B also stops along the front of the folding blade 18. The problem of not being sealed was solved.

Further, it is possible to solve the problem that the first folded recording paper B is pushed out by the later folded recording paper B and moves to a position beyond the range of the envelope paper C. is there.
