4A to 4C are side views of a conventional sensor mark forming apparatus. FIG. 4A shows an image receiving body 2 on which a mark is to be extracted and transferred on a pressing table 1. A transfer recording medium A such as a pressure- or heat-sensitive transfer paper formed by laminating a pressure- or heat-sensitive transfer layer 4, a substrate 3 (for example, a transparent polyester film), and a back coat layer 5 (transparent resin) in this order. The transfer head 4 is attached to the transfer paper 4 with the transfer layer 4 facing downward, and the transfer head 6 attached to the ascending and descending repetitive operation means 8 installed above the transfer paper A is moved downward.

FIG. 4B shows a lower pressing tip 7 of the head 6.
The transfer paper A is pressed against the image receiving body 2 by a (pressing die having a predetermined mark shape), and ascending operation is performed as shown in FIG. 4C, so that the transfer layer 4 of the transfer paper A is transferred to the surface of the image receiving body 2 in a predetermined shape. The transfer layer 4a is withdrawn to the image receiving body 2 side, and a translucent sensor detection mark a having a predetermined shape is formed on the transfer paper A.

FIG. 5 is a front view of FIG. 4, and when a plurality of sensor marks a are formed on the transfer paper A at one time,

Heat of about 150 ° C. is applied to the pressing head 6. Therefore, the uniformity of the transfer pressing force on the sheet-shaped transfer recording medium A at the leading end of the pressing die plate 7 at both ends and the central portion of the pressing head 6 is lost, and the shape of the formed sensor mark a , The size was easy to be unstable.

In addition, a plurality of heat-pressing mold plates 7
In the pressing head 6 of a type integrally provided with one pressing head 6, since the individual pressing forces at the distal end of the heating pressing template 7 cannot be adjusted, the deformation and distortion of the head 6 main body, The quality of the detection mark a was not stable due to variations in the thickness and the smoothness of the silicon rubber 1a provided on the upper surface of the transfer recording medium A, the image receiving member 2, and the pressing table 1, respectively.

According to the present invention, each of the pressing mold plates is provided with an up and down movable mechanism, and the position of each movable mechanism is adjustable with respect to the pressing table in the up and down direction or in the up and down and width directions. An object of the present invention is to make it possible to form a sensor mark having a stable shape, size and quality by individually finely adjusting the pressing force of the pressing die plate tip against the transfer recording medium.

[0008]

The present invention is directed to a transfer recording medium sensor mark forming apparatus having a plurality of press-type plates for pressure transfer or heating / pressure transfer for forming a sensor mark, which can be moved in the width direction of the transfer recording medium. A transfer recording medium sensor mark forming apparatus characterized in that a plurality of reciprocating drive sources capable of individually adjusting the pressing force are attached to a simple bracket, and a pressing template is attached to each of the reciprocating drive sources.

The air pressure applied to the air cylinder attached to each bracket 21 is performed by distributing and supplying compressed air to each air cylinder attached to each bracket 21 by a distributor. Although the air pressure can be adjusted for each air cylinder, approximately 1 kg / cm ² to 6 kg / cm ² is used.

In order for the transfer recording medium A and the image receiving body 12 to be pressed on the pressing table 10 by the lower end of the pressing plate 17 via the cushion sheet 10a, the drive source 18 is required. Pressing plate 17 at the bottom stop of reciprocating motion
It is a matter of course that at least the height of the upper surface of the pressing table 10 is set higher than the height of the lower end portion of the pressing table 10. The lower end of the pressing plate 17 is flat when viewed from the side, and its planar shape can be selected as appropriate, such as a rectangle such as a square or a rectangle, a circle such as a perfect circle, an ellipse, or a polygon. It is.

In the apparatus of the present invention shown in FIGS. 1 and 2, the bracket 21 is provided in one line in the width direction of the transfer recording medium A, but a plurality of lines can be provided. As shown in FIG. 2, the device of the present invention has a transfer agent layer on the lower surface.
4 and a plurality of (for example, x) image receiving members 12 are placed from above on a transfer recording medium A provided with
Individual drive sources mounted on brackets 21
18 (x pieces) are simultaneously lowered and returned, and each pressing mold plate 17 (x pieces) is pressed onto the transfer recording medium A, so that multiple rows (x rows) are formed on the lower surface of the image receiving body 12. 1) The transfer marks 4a having the shape of the template 17 in one row are transferred, and a sensor mark a is formed on the transfer recording medium A as a blank mark.

Subsequently, the transfer recording medium A and the sheet image receiving body
12 is fed to the take-up roll side only at a predetermined pitch interval and stopped. Subsequently, by pressing the pressing mold plate 17 onto the transfer recording medium A, a multi-column (x-column) one-row transfer mark 4a is newly transferred onto the surface of the image receiving body 12, and the transfer recording medium A is A total of two rows (x columns) of two sensor marks a are formed. Thereafter, by repeating the above-mentioned transfer operation, sensor marks are formed on the transfer recording medium A at a predetermined feed pitch interval p as shown in FIG.

[0023]

The transfer recording medium having the transfer agent layer is superimposed on the image receiving body, and the pressing die plate is pressed or heated and pressed from above to remove the transfer agent layer from the transfer recording medium having the transfer agent layer. In the case where sensor marks having a shape corresponding to the template shape as a set area are formed in multiple rows and multiple rows, the present invention device is configured such that each of the pressing template plates is attached to a separate reciprocating body. Therefore, the instability of the pressing force, which tends to occur in the conventional case of pressing the pressing die plate in multiple rows along the unit row in the width direction of the transfer recording medium by a single head, is eliminated, for example, in a single row. Even if uneven pressing occurs, it is possible to adjust the air pressure and the hydraulic pressure of each pressing template individually to set the pressing force of each template in a single row constant.

[0024]

According to the present invention, a part of the transfer agent layer of the transfer recording medium is removed into a predetermined shape, and the sensor marks used for detecting the transfer position of the transfer medium are formed in multiple rows at a time. It is equipped with a pressing die plate for performing, the pressing force of the pressing die plate, air pressure, hydraulic pressure, etc., it is possible to individually adjust the unevenness of the pressing force in the row direction, compared with the conventional It is easy to adjust, and is of practical value in improving the shape accuracy of the mark in forming the transfer medium sensor mark.
