PROBLEM TO BE SOLVED: To provide a temperature recorder with an alarm-generating means that does not generate any alarm when not required and positively generates it only when needed by solving problems such as complexity due to the generation of meaningless alarms on temperature abnormality when a car is not loaded. SOLUTION: When it is discriminated that temperature data deviated from a normal range by a temperature abnormality discrimination means 203 and a cargo room is loaded with cargo by an empty car discrimination means 202, an alarm generation means 300 generates an alarm sound for alarming temperature abnormality in a room by a buzzer-ringing part 301 but does not do so in the other cases. In some cases, the means 300 displays the alarm. |
