Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine, and more particularly to an improvement in a paper feeding mechanism that enables continuous feeding of a plurality of types of documents to be sent to different destinations.

In recent years, facsimile machines have become widespread, and the automation of sending and receiving original documents is progressing more and more. When sending documents, for example, an optical mark reading sheet (hereinafter referred to as
Automation has been realized, such as reading an OMR sheet (referred to as an OMR sheet) in advance of the original, activating auto-dial, and automatically transmitting the original. However, it is not possible to automatically continuously send many types of originals, and there is a need for a facsimile device that can continuously send documents in order to improve efficiency.

[Conventional technology]

The paper feeding mechanism of a conventional facsimile machine will be explained with reference to FIG.

FIG. 2a is a perspective view of the paper feeding mechanism, and FIG. 2b is a side view. In the figure, 1 is a roller, 2 to 4 are sensors for detecting the document paper type, 2 is for detecting A3 size,
3 is for OMR sheet detection, and 4 is for B4 size detection. Further, 6 and 31 are paper feed rollers, 12 is an electromagnetic clutch, 32 is a document presence detection sensor, and 7 is a sent stamp.

The paper feeding operation will be explained.

When transmission starts, the electromagnetic clutch 12 engages,
The paper feed roller 1 starts rotating, and the original 8 is fed. The original 8 is fed by paper feed rollers 31 and 6, scanned at point A, read as an image signal, and then passed through paper feed roller 6 and discharged.
During this time, the type of document paper is read by the sensors 2 to 4, and if the document is an OMR sheet, the image signal is read as transmission data.

When the feeding of one sheet is completed, the feeding roller 1 is stopped by the electromagnetic clutch 12, and after it is confirmed that the reading of the fed original 8 is completed, the next original 9 is fed.
The sensor 32 detects the completion of transmission of all transmitted documents, and a transmission completion process such as stamping a sent stamp on the last document is performed.

[Problem that the invention seeks to solve]

According to the conventional example described above, when the document presence detection sensor 32 detects that there is no unsent document in the document receiver 33, the document transmission completion process is performed. For this reason, there was a problem in that it was not possible to adopt a method in which multiple types of originals were set one on top of the other and sent consecutively.

[Means for solving problems]

The above-mentioned conventional problem is that the OMR sheet containing the transmission information is placed on the first page, and the facsimile machine scans and transmits the first and second multiple types of originals stacked one on top of the other while feeding the paper sequentially. a detecting means for detecting the leading edge of the document being fed to detect the document paper type; and a paper feeding means for feeding the next document when the trailing edge of the document is detected by the detecting means; and a transmitting means, the detecting means is arranged at a position where the next paper type can be detected before the reading of the previous document is completed, and the transmitting means is configured to detect whether the next document is in the OMR sheet by the detecting means. When something is detected, after the transmission of the original being read is completed, the transmission completion process of the first original is performed, and the next second original is successively transmitted based on the transmission information of the OMR sheet. This can be solved with a facsimile machine.

[Effect]

According to the present invention, the paper type of the next document is determined by the detection means before the reading of the previous document is completed.

Therefore, if the next manuscript is an OMR sheet,
The transmitting means determines the document being read (before stamp 7 is affixed) as the first final document, completes the process of transmitting the first document, and then reads the contents of the OMR sheet and sends the second document. Continue sending processing.

Therefore, even if there are originals in the original document tray, different types of originals can be sent continuously.

〔Example〕

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1A is a diagram of a transmission document feeding mechanism according to an embodiment of the present invention, in which A is a side view and B is a front view. FIG. 1b is an explanatory diagram of the operation of the feeding mechanism, and FIG. 1c is a block diagram of the apparatus. Note that the same symbols represent the same objects throughout the figures.

In FIG. 1a, numeral 3 denotes a sensor for detecting the OMR sheet and the trailing edge of the document, and is arranged above the paper feed roller 6 at a distance m. This distance m
The value of is selected such that m>n with respect to the distance n from the document paper type detection sensors 2 to 4 to the leading edge of the next document. The sensor 5 is a sensor that detects whether or not the paper has been reliably fed since the paper feed roller (31 in FIG. 2a) is omitted.

The paper feeding operation under the above conditions will be explained using FIG. 1b.

When the document 8 passes the sensor 3 in FIG. 1 b-a, the electromagnetic clutch 12 is activated, the paper feed roller 1 begins to rotate, and the document 9 is fed. When the original 9 arrives at the original paper type detection sensors 2 to 4,
As shown in FIG. 1b-b, since m>n, the document 8 is passing through the paper feed roller 6. Therefore, manuscript 9
If it is determined that the document 8 is an OMR sheet, the document 8 is determined to be the final document, and transmission completion processing, such as stamping a transmission stamp on the final document, can be performed.

An overview of the operation will be explained with reference to the block diagram of the apparatus shown in FIG. 1c.

In the figure, 20 is a control unit, 21 is a reading unit that reads the image signal of the original, 22 is a modulation/demodulation unit that modulates and demodulates the transmitted and received image signals, 23 is an input/output unit that switches between transmission and reception, etc., and 28 is a recorder that records and reproduces the received image signal. Part, 2
9 is an operation section.

25 is a transmission paper feed control section, 25a is a sensor detection section that detects signals from sensors 2 to 5;
25c is an electromagnetic clutch drive unit that drives the electromagnetic clutch 12 and feeds paper; 25d is a motor that rotates a paper feed roller, etc. This is a motor drive unit.

The operation of the control unit 20 that continuously sends multiple types of documents to different destinations will be described below.

First, fill in the address, document size, number of sheets, etc.
Place the OMR sheet at the beginning of the original to be sent, and load it into the facsimile machine along with other similar originals to be sent.

(1) When transmission starts, the electromagnetic clutch 12 is operated to feed the first document. Next, when the sensor 3 confirms that the document is an OMR sheet, the reading unit 21 reads the data sent from the other party, etc.
It communicates with the other party, and when the transmission criteria are completed, the first document is fed.

(2) The document is placed between paper feed roller 1 and paper feed roller 6.
The paper is fed by During that time, an image signal scanned by the light source 10 and focused through the lens 11 is transmitted through the reading section 21, the modulation/demodulation section 22, and the input/output section 23.

(3) When the trailing edge of the transmitted original passes the sensor 3, feed the next original. The fed document is sent to sensor 3.
If it is determined that the document is an OMR sheet, the document being transmitted is determined to be the final document, a transmission completion process is performed, and the sent stamp 7 is activated.

As described above, since the OMR sheet of the next transmitted document arrives at the sensors 2 to 4 before the preceding document passes through the paper feed roller 6, the completion of transmission can be confirmed, and therefore multiple transmitted documents can be sent continuously. becomes.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to confirm the next manuscript before the transmission completion process, so it is possible to write transmission data at the beginning of the manuscript.
By placing the OMR sheet, multiple types of originals can be fed continuously, and the paper feeding mechanism can be made smaller.
