Description

one

The invention relates to the field of automation and can be used in automatic checkpoint systems.

There are known tokens containing an optical code scale placed in a housing, the disadvantage of which is their low reliability.

To increase reliability, a reflector made of two semi-reflectors with a variable radius of curvature is inserted into the body of the plastic under the optical code scale, and the optical code scale consists of two code shells separated by a transparent window.

The drawing shows a construction tag containing an optical code scale / composed of two semi-shells 2 and 3 separated by a window 4 of transparent material, a reflector 5 of two semi-reflectors 5 and 7 with a variable radius of curvature, a body 8 with a frame for the information carrier and a cover 9 connected to the housing by a hinge 10. A code scale and a transparent window 4 are inserted into the frame of the information carrier and fixed. Each half-shell is provided with a code pattern, made, for example, in the form of a mosaic of separate transparent and opaque elements alternating with each other in a certain sequence depending on the carrier belonging to one or another type of encoding, as well as on the type of encoding.

The reflector 5, located in the housing 8 under the information carrier, is designed to divide the light source of the reading device into two particles, respectively, with two half-shells with a code pattern. The token case 8 is provided with a removable slide, which prevents the information carrier code scale from contacting the front panel of the reader with the checkpoint, as well as for correct orientation of the carrier at the time of reading.

In the token 9 of the token there is a transparent, unbreakable glass, under which there is a blank with unencrypted information about the person who owns the identification card.

The hinge} 0 is intended to bring the information carrier into a working state in which the cover 9 is rotated by 315-320 °, becomes a convenient driver when manually entering information into the reader of the checkpoint.

To read information from user interface to

checkpoint passing

through the item should reveal at 315-

320 ° and enter the guide shells into the response codes on the reader, while, when the window of the storage medium coincides with the window of the reader, information will be read from the token. The rays from the light source of the reading device will pass through the transparent window of the detector, split into two streams by the semi-reflector and pass through the optical half-shells into the receiver of the reader of the checkpoint.

Subject of the invention A token for a checkpoint containing an optical code chip placed in a housing, characterized in that, in order to increase the reliability of the token, a reflector made of two semi-reflectors with a variable radius of curvature and an optical beam are installed in its body The code scale consists of 113 two polushkals separated by a transparent window.
