It is possible to eliminate the stock space in the firing trolley and to reduce the cost without requiring a large number of large and heavy trolleys.

Further, the mounting plate 12 is tilted in the same direction and inserted into the insertion holes 22, 22a ...
Since the mounting plate 12 is arranged so as to be supported by 13 and to overlap the upper portion C1 and the lower portion C2 of the slope of the white background W which is laid down on the mounting plate 12, the conventional white background W is horizontally mounted. Compared to the above, since the projected plane area can be effectively utilized by the amount of overlap between the upper portion C1 and the lower portion C2, the number of sheets to be loaded on the firing carriage 9 can be increased and the continuous production can be performed. Production efficiency can be improved.

Further, the mounting plate 12 has a downwardly expanding tapered hole 17
And a support pin that is inserted into the tapered hole 17
13 Since the upper part is formed in a substantially spherical shape, even if there is a deviation between the standing position of the support pin 13 and the drilled position of the tapered hole 17 of the mounting plate 12 facing this, the tapered hole 17 is expanded downward. Since the taper surface is formed and the head 20 of the support pin 13 has a substantially spherical shape, it is supported by a positional deviation generated within the maximum diameter T of the taper surface, that is, rattling when the support pin 13 is erected. Since the positional deviation of the center of the top due to the inclination of the pin 13 can be absorbed, the installation work of placing the mounting plate 12 on the support pin 13 becomes easy, and the support pin 13 can be set within the range of the maximum diameter T of the tapered surface. Since rattling is allowed, it is possible to roughen the processing accuracy such as the disposition position of the insertion holes 22, 22a for standing the support pin 13 and the hole diameter, which facilitates the processing.

Further, since the supporting head 19 in which the head 20 is formed in a substantially spherical shape is detachably attached to the upper part of the supporting pin 13, when the glazed white background W is fired, from the back side of the white background W. Even if the head 20 is fused to the tapered hole 17 due to the glaze that dripped,
Since only the support head 19 needs to be replaced, the maintenance work can be facilitated and the cost can be reduced, which is a great practical effect.
