Abstract
A closed container in which a reticle etc. is stored and kept is provided with a pressure sensor, transmission means for transmitting data on the pressure, a controller that controls the operation of them, and a battery serving as a power source of the above elements. The controller has a sleep mode in which it causes the transmission means to transmit the data on the pressure at regular intervals and an active mode in which it causes the transmission means to transmit the data on the pressure when necessary in response to an externally supplied command. By the above described configuration, the pressure in the interior of the container can be checked appropriately.
