Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a document ejection mechanism applied to a facsimile machine of a type capable of continuously transmitting a document.

[0002]

[Prior art]

 For a facsimile machine of a model that can continuously send multiple documents, insert a stack document into the document insertion opening that is opened at the front lower part of the main body of the machine, and then perform a send operation to separate the documents from the document insertion opening. The documents fed separately by the paper feed mechanism are passed through the reading section in the main body, and after the reading section finishes reading the image, U-turn is turned upward from the document discharge port opened in the front cover. There is something that was designed to be discharged.

FIG. 3 shows an example of a conventional machine having this type of document insertion / ejection format. In this facsimile machine, when a predetermined transmission operation is performed after the stack original PP is inserted into the original insertion opening 21 formed in the lower front portion of the apparatus main body 20, the separate roller 22 and the separation pad 23 are inserted into the original insertion opening 21. Documents P that are separated and fed one by one by a separation and feeding mechanism that is provided with are first taken in by the feed roller 24 and the nip roller 25 that is in rolling contact with the roller 24, and then read inside the main body. After the image is read by the reading section 26 after being electrically connected to the section 26, the upper front cover is nipped between the exhaust roller 27 provided near the document discharge port and the press roller 28 rollingly contacted with the roller 27. A document discharge port 29 opened at 30 is used to U-turn upward and discharge the document.

That is, a plurality of stack originals PP inserted from the original insertion opening 21 can be continuously transmitted, and the read original Pout is ejected by making an U-turn upward from the original ejection opening 29 and ejecting the original. In order to prevent a document jam near the exit 29, it is essential to install an extract roller 27 for forcibly discharging the document P that has passed through the reading section 26.

[0005]

[Problems to be solved by the device]

 However, in the case where the extractor roller 27 is mounted, the extractor roller 27 and its accessory parts occupy a considerable installation space, and a drive mechanism for operating the extractor roller 27 must also be installed side by side. It is pointed out that the structure of the transmitter becomes very complicated.

The present invention solves such a problem and provides a document discharge mechanism of a facsimile apparatus capable of automatically discharging a document without an extract roller.

[0007]

[Means for Solving the Problems]

 According to the document discharge mechanism improved based on the present invention, a facsimile apparatus which discharges a document, which is separated and fed by a separation / feed mechanism from a document insertion port, through a reading unit and U-turned upward from the document discharge port. In the above, the reading section is composed of a feed platen roller for feeding the original document and a contact image sensor pressed against the roller, and the feed platen roller is arranged just below the original document outlet.

[0008]

[Action]

 In this facsimile machine, the documents fed separately from the document insertion port by the separate paper feed mechanism are fed between the feed platen roller that feeds the document at the reading section and the contact image sensor that is pressed against the roller. It is nipped and read. Then, when scanning of one document is completed, the feed platen roller waits in a rotation stopped state until the next document is fed, and at this time, the end of the scanned document is finished in contact with the feed platen roller. It hangs down from the document discharge port directly above the roller while being nipped with the sensor. From this state, when the next document is fed and the rotation of the feed platen roller is restarted, the previous document to be read comes out of the nip point between the feed platen roller and the contact image sensor, and the document to be read by its own weight. It will fall naturally and will be automatically ejected in front of the document exit.

[0009]

【Example】

 1 and 2 show an embodiment. In this facsimile machine, a document insertion port 3 is opened in the lower front part of the device body 1, and a document ejection port 4 is opened between a front cover 2 attached to the front face of the device body and a panel cover 5 attached to the top face of the device body. When a predetermined transmission operation is performed after the stack document PP is inserted into the document insertion port 3, the documents P that are separated and fed one by one by the separation / feed mechanism provided in the document insertion port 3 are stored in the main body 1. The document Pout is electrically connected to the reading section of the document reading device, and the document Pout from which the document image is read by the reading unit is U-turned upward from the document discharge port 4 and discharged.

Here, as in the conventional example, the separation sheet feeding mechanism provided in the document insertion port 3 is configured by pressing the separation pad 6 against the separation roller 6 and the document end inserted between the both. When the separate roller 6 is rotated in the set state, the lower layer contacting the roller surface is separated and fed one by one, and fed from the document guide 8 to the reading section in the main body 1.

On the other hand, the reading unit is configured by arranging a contact image sensor. That is, a feed platen roller 9 (feeding feed roller) for feeding the document P is provided facing the document feed path fed by the separate roller 6, and the feed platen roller 9 is a unitized contact type image. The reading surface 10a of the sensor 10 is press-contacted so that it can be brought into contact with and separated from it, and the image of the document P that is wound around the roller surface of the feed platen roller 9 and fed into the gap between the sensor reading surface 10a is near the nip point. It is designed to be read by. The feed platen roller 9 and the contact-type image sensor 10 which constitute the reading unit are arranged immediately below the document discharge port 4 for discharging the read document Pout that the feed platen roller 9 has finished reading in the main body 1. ing.

Reference numeral 11 denotes a transmission motor which is mounted in the main body 1 and drives the separate roller 6 and the feed platen roller 9 via a transmission mechanism (not shown).

The operation of discharging the document P at the time of transmission by the facsimile apparatus configured as described above is as follows.

First, when the stack document PP is set in the document insertion port 3 and then a predetermined transmission operation is performed, one by one is fed from the document insertion port 3 by the separating and feeding mechanisms 6 and 7, as shown in FIG. The leading edge of the original P fed separately is brought into conduction with the reading section by the original guide 8, and the original P fed by the feed platen roller 9 is nipped between the roller 9 and the contact-type image sensor 10 pressed against the roller 9. Read. At this time, as shown in the figure, the leading edge side of the document P which has passed between the rollers and the sensor and has been read is sequentially discharged from the document discharge port 4 to the outside of the apparatus. Then, when the reading of one original is completed, the feed platen roller 9 is stopped in rotation until the next original is fed, and stands by in the stopped state. At this time, as shown in FIG. 2, the terminal end Pe of the read document Pout that has been read remains nipped between the feed platen roller 9 and the contact-type image sensor 10 as shown in FIG. Hangs from.

From this state, when the next document is fed and the feed platen roller 9 restarts to rotate, the end Pe of the read document Pout comes out of the nip point between the feed platen roller 9 and the contact image sensor 10. Then, as shown by the chain double-dashed line in FIG. 2, the read document Pout is naturally dropped by its own weight and automatically discharged to the front of the document discharge port 4.

[0016]

[Effect of device]

 As described above, in the document discharge mechanism of the present invention, the reading unit is composed of the feed platen roller and the contact type image sensor pressed against the roller, and the feed platen roller is arranged directly below the document discharge port. As a result, it was necessary in the past for a facsimile machine of the type that allows a document to be separated and fed by the separation / feed mechanism from the document insertion port to pass through the reading section, and to make a U-turn upward from the document ejection port for ejection. Even without an extender roller, it will be possible to exert the automatic discharge function that utilizes the natural fall of documents. Therefore, if this mechanism is adopted, the extractor and its accessory parts can be removed together with the drive system, so the number of parts can be reduced, and the structure of the transmitter and the cost can be simplified.
