Description

[Detailed description of the invention] This invention is a method for recording identification information, including the date, place of publication, and other information that is not written on the manuscript, on the recording paper of the receiving device in the manuscript reading section. The present invention relates to a facsimile device with functions.

More specifically, it relates to a facsimile machine that has a fixed optical system and has the function of adding identification information to a reading device that scans the document while moving it at the sending stage, and recording it on the receiving paper of the other party. It is.

The present invention will be explained in detail below using a facsimile machine as an example.

In conventional facsimile machines, when the receiving side records the image information written on the original sent from the sending side on the received paper and retrieves it, the image information of the original sent from the sending side is sent from where. In order to identify what type of information is received, it is required to add document identification information such as characters, codes, marks, etc. to the image information and record it on the received paper.

Therefore, in conventional devices, in order to add identification information that is not written on the original, the sender writes the identification information on the original to be sent, or uses a carrier that is inserted when sending the original into the reading section. Identification information written on a piece of paper or the like was added to a part of the rear seat.
However, in the former case, it is a hassle to write on the document each time a transmission is desired, and in the latter case, it is a hassle to insert a carrier sheet into the document each time.

To solve this problem, there is a method of using a character generator to add such identification information to the main body of the device. This method using a character generator is a method in which identification information is generated from the generator section and this identification information is synthesized with image information using an electrical signal. However, this character generator has a complicated configuration, and there are limits to the patterns of identification information that can be generated. Therefore, there is a drawback that arbitrary identification information cannot be added to image information. Moreover, in order to generate the necessary identification information to be added by the character generator, a storage device is required to sequentially specify each character of the identification information in a predetermined order, so the entire device is The disadvantage is that the configuration is complicated and expensive.

On the other hand, in systems such as those found in electrophotographic copying machines, where the document table is fixed and the optical system is moved to perform optical scanning, an example of adding identification information is to add pieces of paper with identification information written on them as needed. There is a method of recording identification information in a copied image along with the image information of the original itself by superimposing it on the original on the original table.

However, this method cannot be used in principle with an apparatus such as a normal facsimile machine, which moves the document and reads the document with its optical system fixed.

An object of the present invention is to eliminate the drawbacks of the above-mentioned prior art, and to provide a device that can add exchangeable arbitrary identification information to image information with a simple configuration that could not be achieved with the prior art.

The present invention, which achieves the above object, is a facsimile device that transports a document to an exposure section and reads image information to be transmitted. an identification information carrying roller on which identification information can be removably placed on its circumferential surface; and a removable transparent roller that is wrapped around the roller circumferential surface and covers the identification information placed on the roller circumferential surface. The present invention provides a facsimile device characterized by having a cover.

Hereinafter, an example in which the identification information adding apparatus of the present invention is applied to a facsimile machine that performs plane reading and scanning will be described with reference to the drawings.

FIG. 1 is a sectional view of a facsimile apparatus to which the present invention is applied, in which a document 1 desired to be transmitted is placed on a document table 2 and set at a position where it abuts against a pair of conveying rollers 3. The roller 5 having the identification information 4 on its surface is located at a position where its rotation axis is directly above the exposure section, which is the optical reading position, and is arranged at a distance from the rotation axis of the conveyance roller pair 3. has been done. Reference numeral 6 denotes a member that faces the roller 5 and guides the document being conveyed. The guide 6 may be made of a transparent material such as a glass plate, or may be made of a metal or opaque plastic member provided with a narrow opening in the main scanning direction.

Now, after the person who intends to send the document sets the document 1 in a predetermined position and presses an operation button (not shown), a signal is sent to the drive means, and the conveying roller pair 3 starts rotating, and the document 1 is moved by the arrow Send it out in the direction of a. At the same time, the roller 5 rotates in the same direction as the original and at the same speed in accordance with the transport mode of the original. As an example of driving this roller 5, for example,
Each timing pulley can be fixed to the drive shaft of the transport roller pair 3 and the shaft of the roller 5, and the timing pulleys can be driven by suspending the timing pulleys between them.

On the other hand, the illumination lamp 7 illuminates the identification information 4 on the roller 5 while the document 1 reaches the exposure section, and the reflected light of the information 4 is reflected by the fixed mirror 8 and transmitted through the lens 9 to the CCD element which is the sensor. An image is formed on the photoelectric conversion element 10. In this way, the optical information read by the exposure section is converted into an electrical signal by the element 10 and transmitted to the receiving device of the other party. Note that 11 in the figure indicates a stay for fixing the lens 9 and the photoelectric conversion element 10.

When the operation button is pressed in this way, until the leading edge of the document 1 reaches the reading position, the identification information 4 on the roller 5 is read into the photoelectric conversion element 10 via the optical system, and the information 4 is transmitted to the other party. transmitted to the side.

Next, when the leading edge of the original 1 reaches the reading position, the original image is transmitted until the trailing edge of the original 1 passes through the reading position. This state will be explained with reference to FIG. When reading this document, the document 1 is conveyed while being sandwiched between the guide plate 6 and the roller 5 having the identification information 4.
The reading optical system does not read the identification information 4, but only the image information of the original 1. In this state, the original 1 is fed in the direction of arrow a, and the image information of the original 1 continues to be read until the rear end of the original 1 reaches the reading position. For example, a sensor 12 that detects the presence of a document shown in FIG.
After detecting the trailing edge of the original 1, the reading of the original is continued for a period of time until the trailing edge of the original 1 reaches the reading position, and after that, the photoelectric conversion element 10
If the reading of the image information is stopped, the identification information 4 on the roller 5 will not be read again after the trailing edge of the original 1 passes through the reading position. This control may be performed using a timer so that the element 10 is activated only during the time the document is conveyed from the sensor 12 to the exposure section.

Although not shown, there is a pair of conveyance rollers further downstream of the exposure section, which feeds the original 1 that has been read onto the output tray 13. For this reason,
Even if the rear end of the original 1 comes off the roller 3, the original is transported at a predetermined speed and continues to be read while passing through the exposure section.

Let us consider the above explanation as a recorded image obtained on the received paper. Image information obtained by performing recording scanning on the receiving side in synchronization with the reading scanning on the transmitting side is shown in FIG. Assuming that the arrow d in the figure is the advancing direction of the receiving paper, that is, the sub-scanning direction, the identification information 4 read by the reading side is recorded in an area of length b from the leading edge of the receiving paper, and the subsequent length c is recorded in an area of length b from the leading edge of the receiving paper. Image information from the leading edge to the trailing edge of the document 1 is recorded in the area.

Returning to FIG. 1 again, to supplement the explanation, although the longitudinal direction of the roller 5 is not shown, its length is longer than the width of the document, and it serves as a roller that has the function of discharging the document. May also serve as Also,
In normal cases, it is sufficient that the identification information does not need to be written across the entire width of the document, so its length may be configured to be shorter than the width of the document.

FIG. 4 shows an embodiment of the present invention, and shows a perspective view of a roller 5 which is an identification information supporting means. A recess formed by a stepped portion 5a is formed in a part of the circumferential surface of the roller 5, a sheet 4a on which identification information 4 is written is placed on the circumferential surface of this concave surface, and the entire circumference of the sheet 4a is then read from the top of the sheet 4a. The covering cover 14 is rolled up around the cylindrical portion of the stepped portion 5a. At this time, the circumferential surface of the cover 14 should not exceed the maximum diameter of the roller 5, and the cover 14 itself is made of a colorless and transparent flexible material such as vinyl, and is thin and has a cylindrical shape. Construct into a cut shape. Suitable materials for the sheet 4a include thin, stiff paper or rough plastic film, which have a surface that allows for easy writing with a pencil, ballpoint pen, or the like. On the other hand, the cover 14 may be formed into a cylindrical shape by heating a film made of PETP (polyester) or polyamide resin, for example, to obtain the desired shape. In this embodiment, after the sheet 4a is wrapped around the stepped portion 5a of the roller 5, the cover 14 is fitted to securely hold the sheet 4a, so that a sufficient binding force is required to hold the sheet 4a securely.

Figure 5 shows the seat 4a and cover 14 shown in Figure 4 above.
FIG. 3 is a cross-sectional view of the roller 5 attached to the stepped portion 5a of the roller 5. At this time, the side on which identification information 4 is written is
As long as it is located within the depth of focus of the exposure section, it does not necessarily need to come into contact with the surface of the guide plate 6. When the outer diameter of the roller 5 comes into contact with the guide plate 6 because the roller also serves as a conveyance function, the outer diameter of the cover 14 is set to be smaller than the outer diameter of the roller 5, as shown in FIG. It is desirable to do so.

By the way, by employing the cover 14, the seat 4a can be easily attached and removed, and at the same time, since the cover 14 sufficiently covers the upper part of the seat 4a, the seat 4a can be prevented from getting dirty. .

As explained above, according to the present invention, since the roller carrying the identification information is provided in contact with the guide provided in the exposure section, the reflection during exposure is performed more efficiently than when there is a gap between the two. This improves the resolution of identification information. Furthermore, since a transparent cover is provided to cover the identification information, it is possible to prevent the surface of the identification information from being damaged or stained even though the roller is provided in contact with the guide. In this way, the present invention allows any identification information that can be directly read, such as letters, symbols, and marks, to be captured without damaging the main image information using a simple configuration without using complicated and expensive equipment such as character generators. This can be expected to have the effect of making recording possible and increasing convenience for the user. Further, according to the present invention, identification information can be easily exchanged with a simple configuration.
