To record the measurement result and measurement time of the surface temperature of an article in its distribution process automatically at the same time by providing a clock mechanism and a print mechanism and printing a date and time, and necessary characters, symbols, etc., on a form such as a slip.

The surface temperature of a body is measured by a laser beam projection part 4A and a photodetection part 4B and the measured surface temperature and its measurement time are temporarily stored together in both the main area and temporary storage area of the RAM of a memory 11. With a print switch 7A ON, a printer block 5 is placed in operation to print out the surface temperature data and measurement time data stored in the RAM. Thus, the measured temperature and measurement time can be printed on the body itself or a form such as a slip, so temperature management at necessary timings of the shipment and reception of the body, various processes (cooking), and its storage and who is responsible for them are made clear to complete the sanitary management.
