Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine capable of transmitting both sides of a document.

[0002]

BACKGROUND OF THE INVENTION In the case of transmitting both sides of an original document by a facsimile apparatus which does not have a two-sided transmission function, it is often the case that the back side of the original document is copied in advance and this is set together with the original document on the original table and transmitted. If there is no copying apparatus, the front side of the original is transmitted first, and then the original is inverted and set so that the back side is transmitted.

[0003]

As described above, in the method of copying the back side of the original and setting and sending the original together with the original, it takes time and effort to make a copy, and when the transmission is completed, the original to be copied is There is a problem that the copy paper is wasted because it is unnecessary. Also, in the method in which the front side of the original is sent and then the back side of the original is set and sent, the connection with the communication line is disconnected when the front side finishes sending, so when sending the back side, the call is made again. It is troublesome because it has to be processed.

As a facsimile apparatus having a double-sided transmission function, for example, a facsimile apparatus having document reading portions above and below a document feeding path, or after the front side of a document is read, it is automatically inverted. Although there are facsimile machines provided with a conveying path for supplying them to the reading section again, these facsimile machines have a problem that the structure is complicated and the cost is increased.

Therefore, the present invention solves the above-mentioned problems and proposes a facsimile apparatus which has a simple structure and is capable of transmitting both sides of a document by a simple operation.

[0006]

In order to solve the above-mentioned problems, in the present invention, a reading means for reading the image information described in the document, a storage means for storing the image information, and a transmission for transmitting the image information. And a means for detecting an identification sheet indicating double-sided transmission, and when the identification sheet is detected, the image information for both sides of the document is stored in the storage means and then this image information is transmitted. It is characterized by.

[0007]

In the case of transmitting both sides of a document, the two-sided transmission identification sheet S shown in FIG.
1 is set, and this is read by the reading means 1 of FIG. At this time, the identification sheet S1 is detected by the double-sided transmission identification sheet detection means 3, and the double-sided transmission mode is automatically set accordingly. Next, the front side of the document is read and stored in the storage means 2.

When the reading on the front side is completed, the reading means 1 and the storage means 2 remain in the standby state until the reading on the back side is started. Next, the double-sided transmission identification sheet S1 is set on the front side of the original on the back side, and in this state, the original is set on the reading means 1. Then, the identification sheet S1 is first fed into the reading means 1, and this is detected by the double-sided transmission identification sheet detecting means 3. As a result, it is recognized that the reading is on the back side. Then, the back side of the original is read and stored in the storage means 2.

When the reading and storing of the back side is completed, the rearranged pages are rearranged in order from the first page stored on the front side. Then, when the transmission means 4 performs a calling process and the communication line is connected to the other party, the image information in the storage means 2 is sequentially transmitted from page 1.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of a facsimile apparatus according to the present invention will be described in detail with reference to the drawings.

FIG. 1 shows the functional blocks of the present invention. In the figure, reference numeral 1 is an image information reading means for reading the image information and the double-sided transmission identification sheet written on a document (not shown). The double-sided transmission identification sheet is used when transmitting both sides of a document, and the details will be described later. A storage unit 2 stores the image information read by the image information reading unit 1.

Reference numeral 3 is a double-sided transmission identification sheet detecting means,
When the double-sided transmission identification sheet is fed into the image information reading means 1, this is detected. Reference numeral 4 denotes a transmission means, which is connected to a communication line and transmits the image information in the storage means 2 to the other party.

FIG. 2 shows the structure of this facsimile apparatus. In the figure, 11 is a CP that manages transmission / reception control.
U and 12 are ROMs that store various control programs such as transmission / reception programs, and 13 is a RAM that can store image information for a plurality of pages to be transmitted. The image information read by the document reading unit 14 is stored in the RAM 13 through the interface 15 or directly or directly, and then the modem and the network control circuit (NCU) 1 functioning as a transmitting / receiving unit.
6 is supplied.

The image information input from the communication line is
The data is stored in the RAM 13 via the modem and the NCU 16 or directly supplied to the recording unit 18 functioning as a printer via the interface 17 to record the content. The telephone number of the transmission destination is displayed by being supplied to the display unit 20 via the interface 19. The operation unit 21 is provided with a plurality of keys (not shown), and when these keys are operated, the contents thereof are taken into the CPU 11 via the interface 22. Reference numeral 23 denotes an identification sheet detection unit, which can detect an identification sheet dedicated to double-sided transmission or a general-purpose identification sheet in this example.

FIG. 3 shows double-sided transmission identification sheets S1 and S2 used for double-sided transmission by this facsimile apparatus. The identification sheet S1 of FIG. 4A has the same size as a normal document, and cutouts K1 and K2 of appropriate sizes are provided at the side edge and the lower edge. This notch K1, K2
When either of the two is detected by a sensor (not shown) provided in the document reading unit 14, it is recognized that the duplex transmission is performed.

The identification sheet S2 for double-sided transmission shown in FIG. 2B is provided with band-shaped black marks M1 and M2 instead of the cutouts K1 and K2 of the identification sheet S1. The identification sheet S2 is read by the image reading unit 14 in the same manner as a normal document and is recognized as a double-sided transmission identification sheet.

FIG. 4 shows a general-purpose identification sheet S3 capable of specifying the image quality a, the density b, the presence / absence of a stamp having already been transmitted, the abbreviated number d of the transmission destination, etc. at the time of transmitting an original. The identification sheet S3 is provided with a column e for designating whether to perform double-sided transmission. These identification sheets S1
By attaching S3 to S3 to the original, it is detected by the detection sensor or read by the original reading unit 14. This makes it possible to easily set the double-sided transmission mode without operating the keys or switches of the operation unit 22.

FIG. 5 shows the procedure of the double-sided transmission processing 30 in this facsimile apparatus. In this double-sided transmission processing 30, first, for example, the identification sheet S1 is set at the beginning of the original to be double-sided transmitted, and this is placed on the original plate of the facsimile machine (step 31). With this, the identification sheet S1 is first fed into the facsimile apparatus, and this is detected by the detection sensor to set the double-sided transmission mode (step 32).

Next, the front side of the first page of the original is read and stored (step 33). Then, it is determined whether or not there is a next page (step 34), and if there is a next page, the next page is read and stored in step 33. If it is determined in step 34 that there is no next page, it is determined that the reading of the front side of the document has been completed, and the reading and storing processing remains in a standby state until the reading of the back side is performed (step 35).

Next, the identification sheet S is attached to the top of the back side of the document.
When 1 is set and placed on the platen, the identification sheet S1 is first detected and it is recognized that the back side is read (steps 36 and 37). Next, the first page on the back side of the document is read, and subsequently it is determined whether or not there is a next page (steps 38 and 39). If there is a next page, the next page is read in step 38. Then, if it is determined in step 39 that there is no next page, it is determined that the reading and storing of the back side have been completed (step 40).

Next, preparation for transmission of the stored image information,
That is, when a call is made to the other party and the communication line is connected, the first page on the front side is first transmitted (steps 41 and 42). Next, the last page of the back side, that is, the back side read in steps 38 to 40 is transmitted. As a result, the first page of the first document is first transmitted, and then the back two pages are transmitted.

As described above, only the front side of the original having the image information on both sides is continuously read, and only the back side is continuously read after this is completed, and then the front side is transmitted for each original. After that, in order to transmit the back side, when reading or storing image information or when this is completed, for example, JP-A-56-22225 and JP-A-60-206.
The order of the image information read may be rearranged according to the method disclosed in Japanese Patent No. 267 or the like.

Similar to steps 42 and 43, the front side and the back side of the image information of the remaining originals are sequentially transmitted for each sheet, and it is determined each time whether or not there is image information in the memory ( Steps 44-46). If it is determined that there is no image information in the memory, it is determined that the double-sided transmission has been completed (step 47), and this ends the double-sided transmission processing 30.

[0024]

As described above, the facsimile apparatus of the present invention, when detecting the identification sheet indicating double-sided transmission,
The double-sided transmission mode is automatically set, and the reading and storing processing is continued until both sides of the original are read and stored.

Therefore, according to the present invention, by simply attaching the identification sheet for double-sided transmission to the original, it becomes possible to easily perform double-sided transmission without performing other operations.
