Abstract

PURPOSE:To permit magnetic recording as well without adverse influence of a fixing stage by forming an electrostatic charging area on a carrying body adjacently to an electrostaic latent image region, developing these with a magnetic toner and making magnetic writing in the toner layer corresponding to this charge region. CONSTITUTION:At the time when transfer paper 14 passes through a magnetic recording head 21 after fixing, the necessary information keyed in from a keyboard 23 is written in the uniform magnetic toner layer of a region W2 by the head 21. In this way, this method uses the paper 14 after the copying is used as an original, wherein the transfer paper is inserted into conveying rollers by bringing the region W2 side having the magnetic information facing a magnetic playback head 22 disposed on the operator's side to the operator's side. Then, the information is read when the paper passes through the head 22, and the read information is displayed by a display device. The stable magnetic recording characteristics are obtained.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording method in a copying machine or the like.

Generally, the results obtained from copying machines and the like are only visual information, and cannot be used in automatic search machines, so the scope of use of the results is limited.

However, magnetic recording materials such as tapes, cards, and disks are inadequate as media for visual information.
Single function.

For diversification, it has been proposed to perform both visible image formation and magnetic recording on the same recording medium, and for this purpose, a recording medium coated with a magnetic recording layer is used, and electronic It is known that visible images can be created using photography. However, when forming an image by electrophotography, a heating theorem method is generally used as the electric layer means69, and the surface state of the magnetic recording layer on the recording medium is deformed in this heating electric layer process. , which affects the magnetic recording characteristics performed by the magnetic recording means after the heating electric layer.

The present invention was developed in view of these points, and it is possible to obtain visible information using electrophotography while also performing magnetic recording without being affected by the heating electric layer. The purpose is to obtain a recording method that is possible.

In the present invention, a visible image is created by a normal electrophotographic method using a toner having a 4-meter property, and in this step, a uniform electrostatic area is secured adjacent to the electrostatic latent image area, and the development and Transferring and electrolytic layering are also performed, and magnetic writing is performed on a single layer of stable toner that has been electrolytically layered on the recording medium corresponding to a uniformly charged area, thereby creating a record that contains both visible information and magnetically recorded information. It is configured so that it can be obtained.

An embodiment of the present invention will be described based on the drawings.

This embodiment is applied to a copying machine, and first, a ninth apparatus that implements the method of the present invention will be explained. A photosensitive drum (1) that rotates in the direction of the arrow as a latent image carrier is installed inside the main body of the copying machine. Device(
4), a transfer device (5), a separation device (6), a cleaning device (7), and a static eliminator (8) are arranged in this order. Here, the optical system (3) illuminates the document (6) passing over the contact glass (transfer) and heading toward the document tray a1 by means of the conveyance roller (9), and sends a electromagnetic latent image corresponding to the document image onto the photoreceptor drum. (1) It is formed on top. Also, the current *
The toner used in the device (4) is a so-called magnetic toner, such as a mixture of magnetic powder and 11tMl powder, or a resin granule containing magnetic powder inside. It is used.

Then, the transfer paper CL4 as a recording member is transferred to a transfer device (5) Il by a paper feed roller (B), a registration roller (B), etc.
It is supplied to the transport device o after transfer and separation.
The image is conveyed to the heat fixing device by the heat-fixing device. A paper ejection roller (6) and a tray (2) are provided on the ejection side of the heat fixing device. Further, a magnetic recording head (2) is provided at a predetermined position between the heating fixing device (to) and the paper discharge row 7 (to). A magnetic reproducing head (2) is also provided at a predetermined position between the transport rollers (9).

First, let's talk about the first mode in which a visible image is obtained from an ordinary original (b) and one magnetic writing is performed at the same time.
I will explain. When the document (B) is inserted up to the conveyance roller (9), it is conveyed at a constant speed, and as it passes over the contact glass (G), it is illuminated by the optical system (3) and the Teidenso [(2)
The electrostatic 11F image is then projected onto the uniformly charged photoreceptor drum (1) to form an electrostatic 11F image. At this time, the optical system (3
) Exposure #At by K - By making the charging width narrower than that by the charging device (2) (for example, as shown in Fig. 2, only the front side of the contact glass (to) is formed short), the photoreceptor An electrostatic ## area Wl and an adjacent uniformly charged area Wl are formed on the drum (1). Then, when reaching the developing device (4), the electrostatic ill image in the electrostatic latent image area WIK and the uniformly charged area w1 are simultaneously developed with the toner (2) and visualized.

Next, when reaching the transfer device (5), a transfer operation is performed on the transfer mc14, which is fed with a predetermined timing.

The transferred transfer paper α◆ is separated from the photoreceptor drum (1) by a separating device (6), and sent to a heat fixing device (g) by a conveyance device αη, where it is heated and abrasive. After this, all the development, transfer, and fixing steps for the Seiden Co., Ltd. have been completed and visible image information has been obtained, and the transfer and fixing results have also been obtained in the area w'x of the transfer paper CL4 corresponding to the uniformly charged area W3. A single layer of uniform toner will be formed. Therefore, a magnetic head is disposed on the passage path of this area W1 of the transfer paper O◆, and the transfer paper α◆ after fixing is this magnetic recording head? When passing through υ, the necessary information previously entered on the keyboard 4 is written into the uniform magnetic toner layer in the area WS by the anaerobic recording head. In this case, the single layer of uniform magnetic toner is a fixing technique, and its surface condition is stable as if coated, resulting in good magnetic recording characteristics. In this way, a recorded material having visible image information and magnetically recorded information is obtained on the tray (E).

Next, a second mode for reading magnetically recorded contents from a document (6) having magnetically recorded information will be explained. In other words, transfer paper CL4 that has been copied as described above to original document (2).
It is inserted into the conveyance roller (9) with the area w8 having magnetic information placed on the front side in correspondence with the magnetic reproducing head (2) placed on the front side. This information is read when passing through the magnetic reproducing head (2), and the read information is displayed on a display device (not shown). The electrophotographic process is not performed in this @24-de, and the document (2) after m*p is placed in the document tray Q.
It is discharged to υ.

Next, transfer the transfer paper α◆ obtained as a result of the first mode to the original (6
), and a third mode in which magnetic writing is performed while obtaining visible information from the transfer paper α◆ will be explained. This third mode is a mixed mode of Groups 1 and 2, in which visible image information P1 is obtained in the same way as in the first mode, and magnetic recording information is read by the magnetic reproducing head G11 according to the second mode. It is transferred to the magnetic field and stored magnetically.

Therefore, according to such a copying machine, for example, when copying technical information, "title", "source", "reporter", "content code", "keyword", etc. are written in the magnetic writing area, that is, the area. If this information is written magnetically, the information can be searched quickly and automatically using this magnetic writing area. It can also be used to process confidential information.

In addition, in this embodiment, a method of copying and recording is explained using a manuscript (b), and a method of receiving and recording a facsimile that does not directly use the manuscript (6) is explained, Of course, it can also be used as a recording method. In addition, the information may be inputted by voice like a tape recorder and recorded as an audio signal instead of using a keyboard. A uniformly charged area is formed adjacent to the image area, and magnetic toner is applied along with the static image, transferred and electrically layered onto the recording medium, and magnetic writing is performed on a single layer of toner corresponding to the uniformly charged area. Therefore, when visible image information and magnetically recorded information are obtained on the same recording medium, the magnetic recording characteristics can be stabilized.
