PROBLEM TO BE SOLVED: To provide a simple-structured food service cart capable of displaying the temperature in a compartment even while carrying food. SOLUTION: A first refrigeration temperature display part 74 and a second refrigeration temperature display part 73 are separately secured, and a first hot-reserving temperature display part 79 and a second hot-reserving temperature display part 78 are also separately secured. The driving mode of these display parts is controlled by a relay circuit 97. While a power plug is inserted into an outlet, the temperature inside a refrigeration compartment is liquid-crystal-displayed in the first refrigeration temperature display part 74, and the temperature inside a hot-reserving compartment is displayed in the first hot-reserving temperature display part 78. At the time, the liquid crystal display in the second refrigeration temperature display part 73 and in the second hot-reserving temperature display part 78 is impossible. On the other hand, while the power plug is being removed from the outlet, the temperature inside the refrigeration compartment is displayed in the second refrigeration temperature display part 73 and the temperature inside the hot-reserving compartment is displayed in the second hot-reserving temperature display part 78. At the time, the liquid crystal display in the first refrigeration temperature display part 74 and in the first hot-reserving temperature display part 79 is impossible. COPYRIGHT: (C)2005,JPO&NCIPI
