ード盤を製造する方法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing a so-called pictorial record disc in which a printed paper sheet such as a photograph or a printed matter is encapsulated in a transparent or translucent thermoplastic resin sheet. The present invention relates to a method for producing a good illustrated record disc without causing cracks during molding, and without causing wear and encapsulation molding of these discs.
従来、この種絵入りレコード盤を製造する方法としては
第１図乃至第２図に示すような方法が知られている。Conventionally, the method shown in FIGS. 1 and 2 is known as a method for manufacturing such a record disc with a seed picture.

し小さめに精度よく作製する必要がある。That is, a first thermoplastic resin sheet 4 having a center 273 at the center 2 of the lower mold 1 of a record press mold, and a first printed paper sheet 6 having a center 5 having a photograph or calligraphy printed thereon. Insert sequentially. Similarly, a second thermoplastic resin sheet 1 having a center 819 on the central axis 8 of the upper mold 7 of the press mold
0 and a second photographic or printed paper hollywood 12 having a center hole 11 is inserted in sequence. Next, a thermoplastic resin core material 13, which will become the core material of the record, is inserted between the lower mold 1 and the upper mold 7,
This is to heat and cool both plastics while brewing the upper gold plate 7 in the direction of arrow A. However, in the above method, in particular, the second photographic or printing paper sheet 12 and the second thermoplastic resin sheet 10 inserted into the upper mold 7 are damaged due to vibrations when the upper mold 7 is closed or moved. Since there is a greater risk of falling, these center holes 11 and 9 need to be made slightly smaller than the center axis 8 with high precision.

いて説明する。In this way, the center 811 falls from the center axis 8 and is one height above the other.
1 and 9 are made a little smaller, especially when inserting a photo or printed paper sheet 12 into the center shaft, a crack will occur around the center hole 11, and the press mold will be inserted with this crack still in place. When closed, heated, and pressed, this crack causes even larger cracks after press molding, resulting in the production of defective illustrated records. In addition, if the photographic printing paper sheet 12 is press-formed while it is still falling when the upper mold 7 is closed, the center of the picture on the surface of the code board is worn out, and the picture has a bad appearance. Records will be manufactured. The present invention eliminates these drawbacks, and one embodiment of the present invention will be described based on the drawings from FIG. 3 onwards.
