ンス２ｏの発熱による影響を受けることはない。The power transformer 20 is provided with a pair of mounting pieces 23 and 24, while the lower cabinet mounting plate 21 is provided with a pair of mounting pieces 23 and 24.
VC is integrally provided with bosses 25 and 26 for fixing 24. In this case, heat generation from the bottom surface of the power transformer 20 and the surface on which the mounting pieces 23, 24 are provided causes the mounting pieces 23, 24 to be particularly attached to the bottom surface of the lower cabinet 21 and the frame surrounding the power transformer 20 from all sides. The walls 21a, 21b and bosses 25, 26 that are close to each other and face the surface are more likely to deform. Therefore, as shown in FIG. 7, two heat-resistant members 27 having an L-shape when viewed from the side are used, and mounting pieces 23 are provided between the mounting piece 23 and the boss 26 and between the wall portion 21a and the power transformer 2o. One heat-resistant member 27 is interposed between the mounting piece 24 and the boss 26, and the other heat-resistant member 27 is interposed between the wall portion 21b and the surface on which the mounting piece 24 of the power transformer 2o is provided. Attach the mounting pieces 23 and 24 to the boss 26°2 through this heat-resistant member 2.
6 with screws 28, and the height of the boss 25.26 is made higher than the dimension from the bottom of the power transformer 2o to the mounting piece 23.24, as shown in detail in Fig. 6. The bosses 25 and 26 are arranged so that a gap is created between the bottom of the lower cabinet 21 and the bottom of the power transformer 20 when they are fixed. As a result, the lower cab 2
1 is not affected by the heat generated by the power transformer 2o. At this time, lead wires 29 are placed along the wall 21a to directly connect the left and right printed circuit boards, but this lead wire 29 is also affected by the heat generated by the power transformer 2o due to the presence of one heat-resistant member 27. There isn't.

A heat-resistant member 27 is provided so as to be sandwiched between the
This allows the heat resistant member 27 to be positioned to eliminate its sagging. Therefore, the power transformer 2o can also be installed within the heat-resistant member 27 and the walls 21C, 21, d without bulking up. Furthermore, before the heat-resistant member 27 is fixed with screws, the heat-resistant member 27 can be temporarily held between the bosses 25 and 26 and the ribs 30 and 31.
