PROBLEM TO BE SOLVED: To realize the invalidation of temperature alarming function in switching from a non-cooling state to a cooling state with a simple structure. SOLUTION: A refrigerating showcase 1 comprises a power supply switch 5 having a cooling/non-cooling switching contact 5a interlocking with a power supply ON/OFF contact 5a and a temperature measuring resistance 2 for measuring the inside temperature. When the power supply to the showcase 1 is cut, the contact 5b is ON, and the resistance 2 and a resistor 19 are connected in parallel to each other. When the power supply to the showcase 1 is started, the contact 5b is OFF, and the resistor 19 which was connected in parallel to the resistance 2 is removed. According to this, detection data are suddenly raised, and a CPU 16 determines the switching from non-cooling state to cooling state, and invalids the temperature alarming function for a predetermined time.
