  However, since the top plate support 28 is fixed on the joint 29 so as to cover the top plate support 28 by the protective member 30, the gap can be made invisible. The protection member 30 may be fixed by bonding, or may be fixed by being fitted below the top plate support plate 28. Since the gap is almost invisible, the design is good and the infiltration of water can be prevented, providing highly reliable equipment.

  As described above, in the present embodiment, the top board support has a seam at at least one corner of the top board, and covers the corner of the top board and the top board support at the joint. By having a configuration with a protective member, the gap between the top plate and the heating unit is stabilized only by the top plate support, and the end surface of the top plate is also protected, and the top plate end is smoother and the top plate It is possible to provide a highly reliable, safe and well-designed device that does not expose the end face of the support plate.

  In the description of the present embodiment, the four top plate supports are described, but the same effect can be obtained even if the top plate support is composed of one to three.

  Although the protective member is made of resin, the same effect can be obtained with heat-resistant rubber and metal parts subjected to edge treatment.

  Of course, the same effect as described in the first and second embodiments can also be obtained.
