Description

[Detailed explanation of the invention] The present invention is designed to record identification information that is not written on the manuscript (including tagging, place of publication, and other information) on the recording paper of the recipient's device in the manuscript reading section. The present invention relates to a facsimile machine having the following 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.

For this reason, 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 to the reading section. Identification information written on a piece of paper or the like was added to a portion of the sheet.

However, in the former case, it is cumbersome to write on the document each time a transmission is desired, and in the latter case, it is cumbersome to insert the document into a carrier sheet each time.

One way to solve this problem is to use 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 this generator section and this identification information is combined with image information using an electrical signal.

However, this character generator has a complicated structure and is limited in 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 a character generator, a storage device is also 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, like normal facsimile,
This is a method that cannot be used in principle with an apparatus that moves the document while reading the document with its optical system fixed.

The purpose of the present invention is to eliminate the drawbacks of the above-mentioned prior art, and
It is an object of the present invention to provide a device capable of adding exchangeable arbitrary identification information to image information with a simple configuration, which was not possible with the prior art.

The present invention, which is distantly related to the above object, is a facsimile machine that transports a document to an exposure section and reads image information to be transmitted. a roller having a concave portion on a part of its circumferential surface; a flexible sheet having identification information and a convex portion on a portion thereof; and the convex portion is fitted into the concave portion. The present invention provides a facsimile machine characterized in that a sheet having identification information is removably attached to the peripheral surface of a roller.

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 machine 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 in a position where it abuts against a pair of conveying rollers 3.

The roller 5, which has 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 of 1 from the rotation axis of the conveying roller pair 3. It is set up.

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 original 1 in a predetermined position and presses an operation button (not shown), a signal is sent to the driving means, and the pair of conveying rollers 3 starts rotating.
The original 1 is sent out in the direction of arrow 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 the rollers 5, for example, each timing pulley may be fixed to the drive shaft of the pair of conveying rollers 3 and the shaft of the roller 5, and the timing pulley may be suspended between them. can.

On the other hand, the illumination lamp 7 illuminates the identification information 4 on the roller 5 while the original 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
The signal is converted into an electrical signal by the element 10 and transmitted to the receiving device on the other side.

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, the identification information 4 on the roller 5 is read into the photoelectric conversion element 10 via the optical system until the leading edge of the document 1 reaches the reading position.
Information 4 is transmitted to the other party.

Next, when the line end of the original 1 reaches the reading position, the original image is transmitted until the rear end of the original 1 passes through the reading position.

This state will be explained with reference to FIG.

When reading the original, the original 1 is conveyed between the guide plate 6 and the roller 5 having the identification information 4, so the reading optical system does not read the identification information 4 and only the image information of the original 1 is read. It will be read.

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, after the sensor 12 that detects the presence of a document as shown in FIG. Now, if the reading of the image information to the photoelectric conversion element 10 is controlled to be stopped, the identification information 4 on the roller 5 will continue to be read again after the trailing edge of the original 1 passes the reading position. It disappears.

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 another pair of conveyance rollers downstream of the exposure section, which sends out the original 1 that has been read onto the discharge toilet 13.

Therefore, even if the trailing edge of the document 1 comes off the force button 3, the document 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 image receiving paper, that is, the sub-scanning direction, the identification information 4 read by the reading side is recorded in the area of length b from the leading edge of the image receiving paper, and the subsequent length C is recorded in the area of length b from the leading edge of the image 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

Further, in normal cases, 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 is a perspective view showing an embodiment of the present invention for configuring the identification information 4 to be detachably attached to a roller.

In this example, members 4b are provided as L-shaped hooks at both ends of the sheet 4a on which the identification information 4 is placed.

The hook portion 4b may be formed by, for example, bending a PETP (polyester) sheet into an L shape and adhering it to the sheet 4a, or by bonding it to the sheet 4a by welding or the like to integrate it.

Also, if the material of the sheet 4a is selected appropriately, this sheet material 4
By bending both ends of a, the hook part 4b can be attached to the sheet 4a.
It is also possible to configure it integrally with

As shown in the cross-sectional view of FIG. 5, in the sheet thus constructed, a part of the roller 5 provided with the stepped portion 5a is cut out in the form of a slit to form a concave portion, and the slit portion 5b is formed as a convex portion. The sheet 4a having the identification information 4 written thereon can be fixed to the recessed portion of the roller 5 by pushing in one end of the portion 4b and hanging the hook.

In this case, the width of the slit portion 5b is set to be slightly smaller than the thickness when the hook portion 4b is overlapped, and the hook securely holds the portion 4b when it is fitted into the slit portion 5b. By configuring it in this way, it can be made difficult to fall off.

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.

In addition, the sheet with identification information can be easily and removably attached to the roller circumferential surface as long as the protrusion of this sheet is inserted into the recess provided on the roller circumferential surface. .

Moreover, the roller circumferential surface is not contaminated.

According to the present invention, any directly readable identification information such as characters, symbols, marks, etc. can be used to damage the main image information using a simple configuration without using complicated and expensive equipment such as a character generator. This feature is expected to have the effect of making it easier for the user to record information without having to worry about dogs.

Further, according to the present invention, it is possible to obtain the effect of facilitating the exchange of identification information with a simple configuration.
