Description

BACKGROUND OF THE INVENTION

1. Field of the invention

This invention relates to an apparatus for engraving images and its adaptor, and more particularly, an apparatus for engraving images such as photographs of faces, addresses, names, autographs, the images for engraving information identifying one's identity, the images from a digital camera, scanner or other information taken from a computer through a network on identification cards such as passports, drivers' licenses, employee certificates or credit cards, and its adaptor.

2. Description of the Prior Art

There have been proposed various engraving apparatuses (for example, U.S. Pat. No. 5,232,231, Japanese Patent publication Nos. 115676/1989, 24395/1993 and Japanese Utility Model Publication No. 201762/1988).

According to the conventional apparatus for engraving images on the passports, driver's licenses, employee certificates or credit cards, a magnetic layer is coated on a surface of a plastic card or synthetic paper, and if necessary, a given thin colored layer is coated on a surface of the magnetic layer or synthetic paper, on which a given magnetic picture or image is engraved by a cutting head or a stylus.

When making the passports, driver's licenses, employee certificates or credit cards, the photographs of faces, addresses, names, autographs, the images for engraving information identifying one's identity, etc. are engraved on them together with the position, ID number etc. in order to increase the security of the engraved cards and to avoid their forgery.

Engraving data source can be roughly classified into image data and text data, which are displayed on a personal computer as independent data, and if necessary, they are combined in the personal computer.

In accordance with the conventional engraving apparatus, independent character data and independent image data are inputted by an independent controller.

In addition, it takes a long time and costs much to develop software and data, and it is also necessary for a user to get used to the method of using the conventional engraving apparatus, thus increasing burden of the user and making it difficult to transmit, edit and compress the data and causing much confusion and trouble.

The biggest disadvantage of the conventional engraving apparatus is that when making a personal card, it requres to make engraving apparatus file data such as a face picture, address, name, or autograph of one person independently and to designate all of the files and to collect and integrate the data.

For the media engraving data such as a face picture, address, name, autograph and the images for engraving information identifying one's identity, etc., there are plastic cards in addition to the magnetic or non-magnetic cards.

There are a lot of kinds of the magnetic, non-magnetic cards or plastic cards such as standard sized, large-sized, passport size and other sized cards.

Accordingly, it needs to make a lot of kinds of the expensive engraving apparatuses in accordance with these media and their property.

Further, it is likely that vibrations of an engraving head of the conventional engraving apparatus oscillate the engraving apparatus itself to cause incorrect engraving.

SUMMARY AND OBJECTS OF THE INVENTION

A principal object of this invention is to provide an apparatus for engraving images which comprises a personal computer, a controller, an X-axis pulse motor driver, a Y-axis pulse motor driver, an X-axis pulse motor, a tilt motor driver, a Z-axis head motor having a minute ΔY-axis driver, a stylus and a vacuum pump whereby photographs of faces, addresses, names, autographs, the images for engraving information identifying one's identity, the images from a digital camera, scanner or other information taken from a computer through a network can be automatically and correctly engraved on identification cards such as passports, drivers' licenses, employee certificates or credit cards.

Another object of this invention is to provide an apparatus for engraving images whereby a side-by-side comparison of the original image with an engraved image is not required for an operator so that erroneous inputting of information or wrong engraving of another person can be substantially avoided.

Another object of this invention is to provide an apparatus for engraving images comprising a vibration-preventing unit whereby smooth and correct engraving can be easily carried out without causing vibration.

Another object of this invention is to provide an apparatus for engraving images, which is simple in construction so as to facilitate easy assembly, operation and maintenance.

Another object of this invention is to provide an apparatus for engraving images for a passport, identity card and the like whereby various kinds of adaptors are prepared in advance in order to exchange the desired adaptors without making various kinds of the apparatus for engraving images.

Another object of this invention is to provide an adaptor for use in an apparatus for engraving images on identification cards, which comprises a rectangular table having a positioning groove and a ridge, both being provided around and near a peripheral edge portion thereof, and a plurality of small air openings provided at the given positions through the table whereby an engraved medium can be sucked and located on the table correctly.

Still another object of this invention is to provide an adaptor for use in an apparatus for engraving images which comprises a first rectangular table including a second rectangular table which is rigidly secured at a given obtuse angle to the first rectangular table, and a third rectangular table which is pivotally connected to the second rectangular table so that an engraved medium can be sucked and located on the table correctly.

These and other advantages of the invention will become more apparent from the following detailed description thereof when taken in conjunction with the accompanying drawings.
