    摘要: A data processing device connects to a first display and operates in a power state including a power-off state, a recording standby state, and a power-on state. A second display displays an operation state of the data processing device. A power controller supplies electric power to a driver in the power-on state and the recording standby state, and stops supplying the electric power in the power-off state. The second display indicates that power is ON in the power-on state, and indicates that the power is OFF in the recording standby state and the power-off state. The power controller switches the power state from the recording standby state to the power-on state when a signal instructing start of a recording operation is received from the first display and the power state is the recording standby state.

    摘要: A communication apparatus establishes a one-way data connection and a connection to a network in which messages are transferred in two ways, and includes: a one-way data connection status detecting unit which detects a connection validating request indicating a communication apparatus on a data reception side that data transmission, utilizing the one-way data connection, is possible and a connection invalidating request indicating that the data transmission is impossible, both of which are outputted from the communication apparatus on the data reception side; an apparatus address obtaining unit which obtains an apparatus address with a message via the network when a change from the connection invalidating request to the connection validating request is detected; an address holding unit which holds the apparatus address; and a message transmission continuing unit which responds to the message received via the network based on the apparatus address held by the address holding unit regardless of whether or not the connection invalidating request is detected.
