PURPOSE:To promote the effective utilization of space, by arranging a heating block forming a window hole in a top plate and forming a frame structure to the bottom surface of said heating block so as to envelop the window hole, in case of the captioned conveyer device for a table service counter. CONSTITUTION:A circular window hole 3, which forms a stepped part in its edge, is provided in the central part of a hot plate 2, and a heating block 4, formed in a circular shape larger than that of the window hole 3, is mounted to the stepped part. While the top plate 2 provides in its bottom surface a cylindrical case structure 5 to be arranged so as to envelop an opening of the window hole 3 by stopping a flange part, extending to the outside, by bolts. The case structure 5, the inside of which is filled with a heat insulating material 6, forms a heat insulating layer. And a resistance type heater unit 8, which is provided in the bottom side of the heating block 4 through an insulating material 7, heats the heating block 4. In this constitution, if the heater unit is replaced with an electronic cooling element cooler unit, a single conveyer path can be easily utilized for heating and cooling. By this constitution, effective utilization of space is promoted.
