Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus in which an original conveying path and a recording sheet conveying path are commonly used to downsize the entire apparatus.

[0002]

2. Description of the Related Art Conventionally, there has been known a facsimile apparatus in which a document feeding path and a recording sheet feeding path are made common to downsize the entire apparatus (for example, Japanese Patent Laid-Open No. 61-276469).
(See the official gazette). In this technique, a document is fed to a common conveyance path by an automatic document feeding mechanism for a document, and recording paper stored in a roll shape is fed from a recording paper storage unit by a feeding roller separate from the automatic feeding mechanism. Paper was fed to a common transport path.

There is also known one in which a document feeding path and a recording sheet feeding path are made common, and a standard paper is used as the recording paper instead of roll paper (see, for example, Japanese Patent Laid-Open No. 2-86364). . The technique disclosed in Japanese Patent Application Laid-Open No. 2-86364 is provided with an automatic paper feed mechanism for originals and an automatic paper feed mechanism for recording papers separately, and the originals or recordings are made from the respective automatic paper feed mechanisms. The paper was fed to a common transport path. Further, in the invention of Japanese Patent Laid-Open No. 2-86364, the setting position of the original and the recording paper is on the shared table, and the entire conveying path including the automatic paper feeding mechanism is shared from the setting position.

[0004]

However, in the above-mentioned configuration of the prior art, except for the invention of Japanese Patent Application Laid-Open No. 2-86364, the conveyance path is shared and the device is miniaturized.

On the other hand, in the one disclosed in Japanese Patent Laid-Open No. 2-86364, the paper feeding mechanism is made common, and the apparatus can be downsized, but the original and the recording paper are set on the same combined table. Therefore, when sending, it is necessary to remove the recording paper from the dual-purpose table and set the original, which results in poor workability, and it is easy to forget to insert the recording paper to replace the original with the recording paper. There were also problems such as defects.

The present invention has been made in view of the above-mentioned problems, and a common paper feeding mechanism is used for a common document, even though the original and the recording paper are set at different set positions.

And a cam drive motor 31 and the like. Thus, when the cam 30 rotates to the position shown in FIG. 2, the arm 29 pushes down the pressure plate 21 to separate the recording paper 5 from the paper feed roller 7, and when it rotates as shown in FIG.
It is possible to allow the arm 29 to rise and press the recording paper 5 against the paper feed roller 7 by the compression spring 22. The control of the cam drive motor 31 will be described later. In addition,
The recording paper pressing release device 27 is not limited to the one using a motor and a cam as in the illustrated embodiment, but may be any device that can push down the pressure plate 21 when necessary, for example, a solenoid is used. It may be done.

10 to 12, at both ends of the paper feed roller 7, a separating means pressing release device for separating the separating means 12 from the paper feed roller 7 at least when the recording paper is being fed (when the paper feed roller is reversed). 34 are arranged. The separating means pressing release device 34 includes a pair of operation plates 35A and 35B rotatably held by the paper feed roller shaft 8. Each of the operation plates 35A and 35B has a push-up portion 35a for pushing up the separator holder 14 of the separating means 12 and a document intrusion prevention portion 35b for restraining the leading end of the document at a position outside the outer periphery of the paper feed roller 7. Further, it has a gear 35c on the side surface. A pair of operation plates 35A, 3

(A) Press release position (the push-up portion 35a pushes up the separator holder 14 to move the separator 15 to the feed roller 7).
12B) and the standby position (the push-up portion 35a and the document intrusion prevention portion 35b) shown in FIG.
It can be rotated to a position that does not interfere with.

One operation plate 35A is connected to the drive transmission drum 40 fixed to the paper feed roller shaft 8 via a spring clutch 41, and the other operation plate 35B is fixed to the paper feed roller shaft 8. The drive transmission drum 42 is connected via a spring clutch 43. Here, one spring clutch 41 has one end fixed to the operation plate 35A, and the rotation transmission direction (winding direction) of the one spring clutch 41 indicates the paper feed roller shaft 8 by an arrow B as shown in FIG. When it is rotated in the reverse direction, the rotation of the drive transmission drum 40 is transmitted to the operation plate 35A in the tightening direction, and when the end 41a of the spring clutch 41 hits the rib 45 provided on the document table 1, the drive transmission is performed. It is specified that the drum 40 slips and rotation cannot be transmitted, and thus the operation plate 35A stops. And this operation plate 35A
The stop position of is set to the above-mentioned pressing release position. Thus, when the paper feed roller shaft 8 rotates in the reverse direction, the operation plate 35A also rotates in the reverse direction and stops at the predetermined pressing release position. Therefore, the drive transmission drum 40, the spring clutch 41,
The ribs 45 and the like constitute first rotation transmission means for stopping the operation plate by rotating the operation plate to a pressing release position where the push-up portion separates the separating means from the paper feeding roller when the paper feeding roller shaft is reversed.

One end of the other spring clutch 43 is fixed to the operation plate 35B, and the rotation transmission direction (winding direction) of the other spring clutch 43 is indicated by arrow A in the paper feed roller shaft 8 as shown in FIG. 12 (b). The rotation of the drive transmission drum 42 is transmitted to the operation plate 35B in the tightening direction when it is rotated in the normal rotation direction, and the spring clutch 4
When the end portion 43a of the No. 3 abuts against the rib 46 provided on the document table 1, a slip occurs on the drive transmission drum 42 and rotation cannot be transmitted, and accordingly, the operation plate 35B is set to stop. The stop position of the operation plate 35B is set to the standby position described above. Thus, when the paper feed roller shaft 8 rotates in the normal rotation direction, the operation plate 35B also rotates in the normal rotation direction and stops at the predetermined standby position. Therefore, the drive transmission drum 42, the spring clutch 43, the ribs 46, etc. rotate the operation plate from the pressing release position to the standby position where the pressing portion does not interfere with the document feeding when the paper feeding roller shaft rotates normally. A second rotation transmission means for stopping the operation is configured.

11 and 13, the paper feed roller 7
Is rotatably held with respect to the paper feed roller shaft 8,
A drive drum 48 is fixed to the paper feed roller shaft 8 in order to transmit the rotation of the paper feed roller shaft 8 to the paper feed roller 7. The drive drum 48 has a drive transmission rib 48a, while the paper feed roller 7 has an arcuate groove 49 into which the drive transmission rib 48a is inserted. Thus, when the feed roller shaft 8 starts to rotate normally or reversely, power is not transmitted to the feed roller 7 while the drive transmission rib 48a moves in the arcuate groove 49, but FIG. Alternatively, as shown in (b), when the power transmission rib 48a abuts one end 49a or 49b of the arcuate groove 49, the rotation of the paper feed roller 7 can be transmitted in the direction of arrow B or A. Here, regarding the length of the arcuate groove 49, the paper feed roller shaft 8 starts forward rotation from the position shown in FIG.
When the operation plates 35A and 35B are pressed from the release position,
It is determined that the paper feed roller 7 does not rotate while rotating to the standby position shown in (b) or while performing the reverse operation. Therefore, the operation plates 35A and 35B are not rotated.
There is no possibility that the paper feed roller 7 rotates during the movement of 1 and adversely affects the original 2.

In FIGS. 1 to 4, a common conveying path 5 is provided downstream of the sheet feeding roller 7 for conveying the original document and the recording sheet fed by the sheet feeding roller 7 through the recording position and the reading position.
2 is provided, and the feed roller 5 is provided in the conveyance path 52.
3, a pinch roller 54, a B point sensor 55, a reading unit (not shown) for reading a document, a recording unit for recording received information on a recording sheet (in this embodiment, an ink cartridge 56 having an ink jet recording head, A DC motor 57 for scanning the ink cartridge 56, a timing belt 58, etc.), a discharge roller (not shown), etc. are provided. The feed roller 53 and the discharge roller are also rotationally driven by the roller drive motor 10 for driving the paper feed roller 7 via a gear train (not shown). A switching gear is provided in the gear train so that the feed roller 53 and the discharge roller rotate in the forward rotation direction regardless of whether the roller drive motor 10 rotates in the normal rotation or the reverse rotation. Instead of this, the feed roller 53 and the discharge roller may be driven by separate motors. Here, the transport speed of the feed roller 53 and the discharge roller is set to be slightly higher than the document and recording paper feed speed of the paper feed roller 7. In FIG. 4, reference numeral 60 denotes a pinch roller which is pressed against the paper feed roller 7 to the lower side and the lower side.

The operation of the facsimile apparatus configured as described above will be described below with reference to the flow chart of FIG. 14 showing reception and the flow chart of FIG. 15 showing transmission.

In the normal standby state, as shown in FIGS. 2 and 4, the operation plate 35A (and 35B) is in the standby position, and the pressure plate 21 of the recording paper tray 4 is pushed down by the arm 29. The recording paper 5 is separated from the paper feed roller 7. Note that the original 2 may or may not be set on the original table 1.

At the time of reception, the roller drive motor 10 starts rotating in the reverse direction in response to the incoming signal, and rotates the paper feed roller shaft 8 in the direction of arrow B. Due to the reverse rotation of the paper feed roller shaft 8, as shown in FIG. 5, the operation plate 35A (and the operation plate 35B interlocking therewith) rotates in the direction of arrow B, and when the original is set on the original table 1, the original is set. The intrusion prevention unit 35b pushes the leading end of the original 2 upward so as not to contact the paper feed roller 7, and then the push-up unit 35a rotates the separator holder 14 upward to move the separator 15 to the upper side as shown in FIG. The pressure on the paper feed roller 7 is released. As a result, the separator 15 is separated from the paper feed roller 7, and the separator 15 is prevented from being turned up when the recording paper is fed. Operation plate 35A (and 35B)
Moves to the pressing release position shown in FIG. 6 and stops there.

Next, or in parallel with the above operation, the cam drive motor 31 rotates, and as shown in FIG. 3, the cam 30 is rotated to a position that allows the arm 29 to swing upward. This causes the pressure plate 21 to move the compression spring 2
The recording paper 5 is pushed upward by 2 and is pressed against the paper feed roller 7 as shown in FIG. Then, the cam drive motor 31 stops.

Thereafter, the paper feed roller 7 starts to rotate in the reverse direction indicated by the arrow B as shown in FIG. 7, and only the uppermost recording paper 5 from the recording paper 5 in the recording paper tray 4 is started. Separate and feed. The fed recording paper 5 is the feed roller 5
3 is further conveyed, and when the B point sensor 55 is turned on as shown in FIG. 8, the cam drive motor 31 is turned on as shown in FIG.
Rotate to rotate the cam 30, push the arm 29 downward and push the pressure plate 21 back to the lowest position (see FIG. 2), separate the recording paper 5 in the recording paper tray 4 from the paper feed roller 7, and move the cam. The drive motor 31 stops. As a result, the back tension applied to the recording paper 5 being fed by the paper feeding roller 7 is released, and the recording paper 5 is fed by the feed roller 5
Stable sent by 3.

The feed roller 53 continues to convey the recording paper 5, and after the point B sensor 55 is turned on and the fixed amount is fed, the printing operation by the recording means is started and the reception recording on the recording paper 5 is performed. After the printing is completed, the recording paper 5 is ejected. Although not shown in the flowchart of FIG. 14, if the reception information continues after the recording paper 5 is ejected, the cam drive motor 31 is rotated again to cause the cam 30 to move.
Is rotated to a position that allows the arm 29 to swing upward, the compression spring 22 pushes up the recording paper 5 and presses it against the paper feed roller 7, and the rotating paper feed roller 7 causes the next recording paper 5 to move.
Is fed, and reception recording is performed by the above procedure.

When the last received information is recorded on the recording paper 5 and is discharged, the roller drive motor 10 reverses its rotation direction, and therefore the roller drive motor 10 starts rotating in the normal rotation direction, and the paper feed roller shaft is rotated. 8 is rotated in the direction of arrow A in FIG. The rotation of the paper feed roller shaft 8 causes the operation plate 3
5A (and 35B) also rotates in the direction of arrow A,
a moves downward. Thereby, the separator holder 1
4 is rotated downward by the holder pressing spring 16,
The separator 15 is pressed against the paper feed roller 7. The operation plate 35A (and 35B) rotates to the standby position shown in FIG. 4 and stops, and then the roller drive motor 10 also stops. As a result, the original standby state is restored. At this time, since the paper feed roller 7 does not rotate, the original 2 is not fed. Reception recording is performed as described above.

Next, when transmitting, as shown in FIG. 4, the original 2 is set on the original table 1 and the transmitting operation is performed. Then, the roller drive motor 10 rotates in the normal rotation direction, and accordingly, the paper feed roller 7 also rotates in the normal rotation direction indicated by the arrow A, and the document 2 is fed. At this time, the operation plate 3
5A (and 35B) is in the standby position, so separator 1
Reference numeral 5 is pressed by the paper feed roller 7, and the originals 2 can be separated and fed one by one. Further, since the recording paper 5 is separated from the paper feed roller 7, the rotation of the paper feed roller 7 does not adversely affect the recording paper 5. After the fed document turns on the B-point sensor and the feed roller 53 sends a fixed amount, the reading is started, and the read document is discharged. Here, when the fed document 2 starts to be conveyed by the feed roller 53, the document is simultaneously fed by the feed roller 53 and the paper feed roller 7. At this time, the feed speed by the feed roller 53 is slightly low. Since it is set to be faster, the paper feed roller 7 is pulled by the document 2 conveyed by the feed roller 53 and rotates a little faster than the paper feed roller shaft 8. At this time, the idling of the sheet feeding roller 7 with respect to the sheet feeding roller shaft 8 is as shown in FIG.
a is allowed by moving in the arcuate groove 49.

When the trailing edge of the original 2 conveyed by the feed roller 53 leaves the paper feed roller 7, the paper feed roller 7 stops rotating. On the other hand, since the paper feed roller shaft 8 continues to rotate normally,
When the drive transmission rib 48a that rotates integrally with the paper feed roller shaft 8 moves in the arcuate groove 49 and hits the end 49b thereof, the paper feed roller 7 moves integrally with the paper feed roller shaft 8 in the forward direction. Start spinning. As a result, the next original 2 is sent out from the rear end of the original 2 sent at an appropriate interval, and the original is read in the same manner as the above-described procedure.
Then, after the last document is sent out by the paper feed roller 7, the reading is completed and the document is discharged, the roller drive motor 10 is stopped and the standby state is set. The transmission operation is performed as described above.

As described above, in this embodiment,
By rotating the paper feed roller 7 in the forward direction with the recording paper 5 set in the recording paper housing 3 separated from the paper feed roller 7, the original can be fed without interfering with the recording paper. Further, by rotating the paper feed roller 7 in the reverse direction with the separator 15 separated from the paper feed roller 7, it is possible to feed the recording paper without interfering with the original and the separator 15, and the paper feed mechanism for the original and the recording paper. Therefore, the device can be downsized.

Next, the facsimile apparatus of the second embodiment shown in FIGS. 16 to 18 will be described. The second embodiment is an embodiment of the invention of claims 4 to 6, and FIG. 16 is a perspective view showing a schematic configuration of a main part of the facsimile apparatus.

The same or similar parts as those in the first embodiment described above are designated by the same reference numerals and the description thereof will be omitted.

In this embodiment, one paper feed roller shaft 8 is arranged between the front end of the original table 1 and the front end of the recording paper storage unit 3, and the paper feed roller shaft 8 is connected to the paper feed roller shaft 8. The transmission paper feed roller 64 is held via the first one-way clutch 63 that transmits only the rotation in the forward rotation direction (arrow A direction), and only the rotation in the reverse rotation direction (arrow B direction) of the paper feed roller shaft 8 is retained. The receiving and feeding roller 66 is held via the second one-way clutch 65 that transmits. The separating means 12 is provided above the transmission paper feed roller 64, and the separator 15 is pressed against the transmission paper feed roller 64. Incidentally, this separating means 1
No means for releasing the pressing of the second transmission paper feeding roller 64 is provided.

In the recording paper tray 4 set in the recording paper storage unit 3, the pressure plate 2 is provided as in the first embodiment.
Although a recording paper pressing means 20 including 1 and a compression spring 22 is provided, the pressure plate 21 used here includes:
A cutout portion 68 is formed in a region of the leading end that abuts the transmission paper feed roller 64. As a result, even when the recording sheet 5 is pushed up by the pressure plate 21, the pressing force of the recording sheet 5 against the transmission sheet feeding roller 64 is small.
The recording paper storage unit 3 is provided with a recording paper pressing release device that separates the recording paper 5 from the transmission paper feeding roller 64 and the reception paper feeding roller 66 by pushing down the pressure plate 21. As the recording paper pressing release device, the same device as that provided in the first embodiment can be used.

The receiving / feeding roller 66 may be an ordinary cylindrical roller, but in the present embodiment, a half-moon roller having a circumferential length of a half-moon arc equal to or longer than the length of the conveying path to the next feed roller 53 is used. ing.

By this rotation, the transmission paper feed roller 64 also rotates in the direction of arrow A, and the originals 2 are separated by the separator 15 and fed one by one. When the fed document 2 reaches a point B sensor (not shown), the feed roller shaft 8 is disengaged and stopped, and the transmission feed roller 64 is pulled by the document being conveyed and idles. When the trailing edge of the original passes the point B sensor, the clutch is re-engaged and the feed roller shaft 8 starts to rotate in the normal direction to feed the next original. In the same manner, documents are fed and read and transmitted. During this operation, the receiving / feeding roller 66 is stopped at the fixed position shown in FIG. 18 by the stopper spring 71 so that it does not interfere with the document to be fed. Further, since the recording paper 5 is also separated from the paper feed rollers 64 and 66, there is no interference.

Next, at the time of reception, as shown in FIG. 18, the paper feed roller shaft 8 rotates in the reverse direction indicated by the arrow B, and the pressure plate 21 is released in parallel with it,
The recording paper 5 is pushed up by the compression spring 22 and pressed against the receiving paper feeding roller 66. As a result, the uppermost recording paper 5 is fed by the receiving paper feed roller 66. When the fed recording paper 5 passes the feed roller 53 and the B point sensor is operated, the recording paper pressing release device causes the pressure plate 2 to move.
1 is pushed down to release the recording paper 5 downward, and the paper feed roller shaft 8 is disengaged from the clutch to stop.

Is positioned at the recording paper feeding position, the pressure plate 21 is released in parallel with it, and the recording paper 5 is pushed up by the compression spring 22 and pressed against the paper feeding roller 7. As a result, the uppermost recording paper 5 is fed by the paper feed roller 7. When the fed recording paper 5 passes the feed roller 53 and the B point sensor is operated, the recording paper pressing release device pushes down the pressure plate 21 to release the recording paper 5 downward, and the paper feeding shaft 75 causes the roller to move. It is disconnected from the drive and stopped. On the other hand, the received information is recorded on the recording paper 5 sent out and is discharged. Hereinafter, the same operation is repeated until the received data is exhausted, and the reception recording is performed. During this receiving operation, the paper feed roller 7 moves downward and separates from the separator 15. At this time, even if the original 2 is set on the original platen 1, the separator 15 is placed on the leading end of the original platen 1. The contact prevents the original 2 from entering and there is no problem.

As described above, also in the third embodiment, by rotating the paper feeding shaft 75 in the normal direction, the paper feeding roller 7 is moved to the original document feeding position and rotated in the normal direction without interfering with the recording paper. The original can be fed, and by rotating the paper feed shaft 75 in the reverse direction, the paper feed roller 7 is moved to the recording paper feed position and rotated in the reverse direction, so that the recording paper can be fed without interfering with the original. It is possible to reduce the size of the apparatus by combining the original and recording paper feeding mechanisms into one.
