Abstract:
1. A closed container for storing an object to be stored that is managed in a clean environment, comprising: a main body having an interior space in which said object can be stored and an opening that allows communication between said interior space and an external space; a lid that can close said opening; an environmental parameter measuring apparatus that can measure at least one parameter indicative of a condition of the environment in said interior space; transmission means for transmitting data representing a measurement result obtained by said environmental parameter measuring apparatus; a controller that controls operation of said environmental parameter measuring apparatus and said transmission means; a battery serving as a power source for said environmental parameter measuring apparatus, said transmission means, and said controller; a mode changing system which is separate from said controller and controls operating modes of said controller; and a radio communication module provided on said closed container and configured to receive an operation command signal which is externally supplied and transmitted to said controller, and to receive a mode changing command signal which is externally supplied and transmitted to said mode changing system, wherein said controller has a sleep mode, as one of said operating modes, in which said controller causes said environmental parameter measuring apparatus to operate and said transmission means to operate at regular intervals to transmit said data and an active mode, as another one of said operating modes, in which said controller causes said environmental parameter measuring apparatus to operate in response to said operation command signal, and causes said transmission means to transmit said data, and said radio communication module provides said mode changing command signal to said mode changing system, which causes said mode changing system to control said controller, based on said mode changing command signal, to execute one of said sleep mode and said active mode by providing a corresponding instruction to said controller.
