PURPOSE: To make it possible to accurately position a heater and a heat luminescence material, which is held in a card, relative to each other by providing the heater in a main housing and by providing the card driving plate slidably in the main housing.
CONSTITUTION: A card 9 holding a heat luminescent material 11 is held in the case body of a heat luminescence metering element. This card 9 is moved by sliding a driving plate 77 in a groove 76, which is formed in a main housing 52, because the engagement projection 78 of the driving plate 77 engages with the recess 13 of the card 9 within the heater. The card driving plate 77 is equipped with a rack 114, and a gear 69 is turned by driving a step motor 67 so that the card driving plate 77 is slid. The main housing 52 and an auxiliary housing 55 are positioned by guide rods 54 and 54' thereby to align the heater in the main housing with the photoelectron multiplier mounted in the auxiliary housing.
