Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is used in conjunction with an information processing device such as a computer or a personal computer, and prints information (signals) from the information processing device on paper using ink or the like. Regarding printers used to record text and graphic information, in particular, a magnetic input/output means that can write or read information on a magnetic recording band provided on a part of the paper is used in conjunction with the printing means to print on the paper. This invention relates to a printer with a magnetic input/output mechanism that can be moved in one direction for writing and reading.

[Conventional technology]

Information processing devices, which have been widely used in recent years, can input information from paper tapes, cards, and keyboards, calculate numerical values at high speed, and classify and categorize data, but the results of this processing cannot be visually displayed. Therefore, it is necessary to print it on paper for identification and storage. For this reason, it is common to use a printer that is connected to an information processing device and records the results of processed information on a sheet of paper using a method such as dot matrix or inkjet.

In this case, in order to print a large amount of information on a large amount of paper in a large information processing device, a full-time operator works using magnetic tape, magnetic disk, etc. It is easy to match the information, and storage media can be managed systematically.

However, small information processing devices such as microcomputers and personal computers, and single-function devices such as Japanese word processors and graphic processing devices are not operated by full-time operators, and
Storage devices such as magnetic disks and floppy disks were often used as information storage media. In order to store specific information in this storage device and retrieve this record at a later date, a unique operation using the file number attached to each piece of information must be performed. In some cases, errors occur during writing or other operations and the desired information cannot be retrieved, causing trouble.

In addition, in the method using a floppy disk, the name of the graphic information file on the floppy disk may not necessarily match its contents, or if multiple files exist, files with similar contents may have similar names. Easy to attach,
In information sorting work, a file different from the target file is often called up, which makes the work inefficient. For this reason, a special paper with a magnetic recording band is used as a part of the paper, and at the same time a printer prints characters, figures, etc. on the surface of the paper, information corresponding to the information printed on the magnetic recording band is printed magnetically. A method has also been proposed in which the information content is visually confirmed and the electrical information (signal) is read from the magnetic recording medium using this paper.

This method requires a special printer to be used to write and read data by sliding a magnetic head onto the magnetic recording strip at a constant speed, which requires a drive mechanism for the magnetic head, resulting in a complicated structure. However, maintenance and assembly were troublesome.

[Problem that the invention seeks to solve]

For this reason, instead of being connected to an information processing device, magnetic recording means is provided in a typewriter or a printing device equipped with a printer head as a printing device, and this magnetic recording means allows the typewriter or printer head to print. Techniques have been proposed for magnetically recording the same content on the same piece of paper using magnetic recording means (for example,
137717, Japanese Patent Application Laid-open No. 104200 of 1972).

However, these technologies simply magnetically record and print the printed content on a magnetic recording strip provided on the surface, and do not read the information stored on this magnetic recording strip again. . For this reason, magnetic recording is performed using the same printing device, and the magnetically recorded information is taken in.
It is not possible to perform information processing, and it is necessary to read the magnetically recorded information using a magnetic read-only device, which poses a problem that makes it unsuitable for use by connecting to a simple information processing device.

The present invention has been made in view of the above-mentioned drawbacks.
A printer with a magnetic input/output mechanism is provided with a magnetic input/output means for magnetically recording and reading in synchronization with a printing means, and is capable of reading information magnetically recorded by the same printing device and performing information processing. The purpose is to provide.

[Means for solving problems]

The present invention relates to a printing means that is connected to an information processing device and prints characters, figures, etc. output from the information processing device on the front side of a sheet of paper, and a printing means that writes or prints information on a magnetic recording band provided on a part of the back side of the sheet. In a printer with a magnetic recording mechanism, the printer is equipped with a magnetic input/output means for reading and outputting the read information to an information processing device, and a driving means for moving the printing means and the magnetic input/output means in one direction of the paper. The input/output means is provided in a U-shaped paper inserter provided above the platen of the printing means so as to be movable in the axial direction of the platen in contact with the magnetic recording band of the paper, and is connected to the printing means. The magnetic input/output means is characterized in that it is driven by a wire reel provided on the same motor drive shaft and is moved synchronously in a direction perpendicular to the paper conveyance mechanism.

[Effect]

The printer with a magnetic input/output mechanism of the present invention is connected to an information processing device, prints information output from the information processing device, and prints information in a direction perpendicular to the conveyance direction of paper in synchronization with the printing printer head. A moving magnetic head records the contents on a magnetic recording band on the back side of the paper.

When magnetically recorded information is imported into an information processing device, a sheet of paper is inserted into a printer, and a magnetic head reads the information recorded on the magnetic recording band and outputs it to the information processing device for information processing. During this reading, the printer head for printing also moves synchronously, but does not perform printer operation.
