摘要:
A multi-function apparatus having a wider variety of uses and easily employed when carrying a USB cable only without having a power source cord. The apparatus includes means for detecting a connection between the USB interface and the PC, means for detecting a connection to the power line, and control means for selecting a function depending on a detected state of the connection between the USB interface and PC and a detected state of the connection to the AC power line. All the functions in the multi-function apparatus are operable in a connected state of the AC power line to the AC power source, while even in an unconnected state of the AC power line to the AC power source, if the USB interface is connected to the PC, a possible operation is enabled using electric power of 5 V at 500 mA supplied from the PC.

摘要:
A voice storage device monitors wireless signals from a plurality of fixed terminals and a plurality of mobile terminals, which are connected to a main unit. When a channel establishment signal is generated by one mobile terminal, the voice storage device detects this signal, and prepares for recording the contents of a speech communication. Subsequently, the fixed terminal generates a channel assignment signal. Thereafter, the voice storage device detects a call setup signal (an ID signal and control information) exchanged between the mobile and fixed terminals, and waits for detection of a response signal which is generated by the mobile terminal and indicates that the call is answered. Upon detection of the response signal, the voice storage device starts a storage operation of voice data at a corresponding one of different storage positions in units of mobile terminals, which position is specified by the call setup signal.
