Abstract

(57)【要約】 光学式に読み取り可能なデータキャリヤをコーティングするための簡単で安価な方法を提供するために、片面接着式の透明な接着フィルムをデータキャリヤの保護しようとする表面に被着するようにした、光学的に読み取り可能なデータキャリヤをコーティングするための方法及び装置が提案されている。さらにまた、保護層が片面接着式の接着フィルムを有する、透明な保護層を備えた光学式に読み取り可能なデータキャリヤが設けられている。 (57) Abstract In order to provide an easy and inexpensive method for coating optically readable data carriers, a single-sided transparent adhesive film is applied to the surface of the data carrier to be protected. A method and apparatus for coating an optically readable data carrier has been proposed. Furthermore, there is provided an optically readable data carrier with a transparent protective layer, the protective layer having a single-sided adhesive film.

を、面倒な後作業で取り除く必要がある。Optical data carriers, such as CDs, as well as methods and devices for producing them are known in the art. A data carrier of this type
It typically has a data-bearing surface that needs to be protected against environmental conditions. In order to protect the surface, a curable paint (Lack) is conventionally used. The coating is applied to the central region of a high speed rotating data carrier, which is then forced outward by centrifugal force to form a substantially uniform layer on the CD. However, in this case it is necessary to rotate the data carrier at high speed in order to obtain sufficient centrifugal force for the paint to be evenly distributed on the surface to be protected. This step risks damaging the data carrier. Furthermore, in this method, it is necessary to remove the excess paint that has been repelled from the data carrier by a troublesome post-work.

The use of an adhesive film has the advantage that the centrifuge step for coating the data carrier with paint is dispensed with and no remnants of the splashed paint that require tedious removal work occur. To be Adhesive films also provide a simple and inexpensive solution for coating data carriers.

In order to be able to be peeled off from it, the laminating film 23 is turned into an acute angle, whereby one side of the adhesive film 25 is exposed for adhering the data carrier 6. The operation of peeling off the protective film 24 is clearly shown in FIG. After being peeled off, the protective film 24 is wound around a roller (not shown). Instead of the wedge-shaped blade 40, a selective shape of the film peeling device may be used.

Is reciprocally movable in the longitudinal direction via a driven roller 34 until the sensor 45 detects a predetermined contoured shape of the punched section 27, for example a punched central hole. When the sensor 45 detects the central hole, the sensor 45 is positioned directly on one edge of the central hole by the motion of the film, which causes the roller 34 to move.
And in particular in the longitudinal direction of the laminate film 23 in relation to the pressure roller 33
An exact alignment of 7 is obtained.

The support and transport unit 47 forms a horizontal support for the data carrier 6 and is movable in all directions via a tilting movement device (not shown). A correct alignment of the data carrier 6 on the support and transport unit 47 is ensured via the descendable centering pin 48. The pins 48 can be lowered during the laminating process so as not to interfere with the laminating process. This is done by pressing the pin 48 upwards into the position shown in FIG. 3 by a spring having a relatively small spring force. Pushing the pin upward pushes the pin downward against the spring force. Alternatively, the pin can be moved via a cylinder or a motor.

２７に関連したデータキャリヤ６の横方向の整列が可能である。Before depositing the laminate film on the data carrier 6, the transport and support unit 47 is moved towards the stopper in the X-direction, which corresponds to the longitudinal direction of the laminate film 23. Thereby, the data carrier 6 and the previously longitudinally aligned section 27 of the adhesive film 25 are aligned with each other. Then, the transporting and supporting unit 47 is reciprocally moved in the Z direction extending in the lateral direction orthogonal to the longitudinal direction of the laminate film 23. The contour shape such as the contour shape of the central hole of the punched section 27 of the adhesive film 25 is detected via the pair of sensors 50 assigned to the transport and support unit 47. This allows lateral alignment of the data carrier 6 with respect to the section 27.

The rollers 34 are then driven via the motor 32, which causes the laminating film 23 to move in the X direction. Simultaneously with the rotation and in synchronization with the rotation, the transport and support unit 47 is moved in the X direction. In this case, the section 27 comes into contact with the surface of the substrate 6 to be protected and is pressed against this surface by the pressure roller 33, which causes the section 27 to move.
And is peeled off from the support film 26. Due to the synchronous movement of the transport and support unit 47 and the drive roller, the section 27 of the adhesive film 25 is centered and glued on the data carrier 6, so that the section 27 of the film 25 is protected by the side of the data carrier 6 to be protected. Completely covered and never project beyond the edge. The pressure force of the pressure roller is controlled in the Y direction on the position of the transport and support unit 47 in order to adjust the adhesive properties of the adhesive film 25. Of course, it is also possible to selectively move the crimping force 33 in the direction of the transport and support unit. A spring-loaded suspension system may be provided for better adjustment or compensation of the crimping force. Spring suspension is provided via a spring or compressed air cylinder.

The same reference numerals are used in FIG. 4 wherever the same or similar parts are described. The laminated film 23 is also composed of three films, that is, the protective film 24.
And a single-sided adhesive film 25 and a support film 26. Unlike the previous examples, the adhesive film does not consist of one layer of adhesive material. Rather, the one-sided adhesive film 25 includes an adhesive layer 60 and a protective layer 62 (for example, a PC tape). Due to the PC tape, the adhesive film additionally has shape stability, and furthermore the PC tape has special optical properties which are particularly advantageous in DVR. The adhesive film 25 further has the above-mentioned section punched out according to the size and shape of the surface of the data carrier to be adhered. In this type of adhesive film, the process station 11 can be omitted. This is because it is not necessary to cure the adhesive film.

The data carrier may be housed in a casing, for example in the form of a floppy disk. This severely limits the mechanical requirements of the coating. In this case, the process station 11 can be omitted. This is because no additional process steps are required after laminating the adhesive film (adhesive layer). After curing of the adhesive layer, it can be done by pressure and / or time and / or irradiation (eg UV light) or heat treatment.
