    • In a pager receiver for receiving first through N-th pager signals successively at a first predetermined period (T1) and comprising a battery saving switch and a receiving circuit connected to the switch and enabled while the switch is in an on state, a controller puts the switch in the on state repeatedly at a second predetermined period (T2) to make the receiving circuit receive at least a portion of a preamble signal (PA) and whole of a synchronization (SS) and an address (AS) signals of the first pager signal (RS1) and detect an address signal end of the first pager signal. The controller keeps the switch in the on state to make the receiving circuit receive at least a part of the preamble signal and whole of the synchronization and the address signals of each of the second (RS2) through the N-th pager signals and detect the address signal end of each of the second through the N-th pager signals. The controller puts the switch in the off state from detection of the address signal end of each signal of the first through the N-th pager signals until lapse of a preselected duration (D3) from reception of the synchronization signal of the each signal.

    • A pager receiver for a radio calling signal carrying a call number and/or a message comprises a processing unit for producing a drive and an information signal to produce ordinary tone or tones related to the call number and to provide ordinary visual displays representative of the message, respectively. A processed signal is produced by the processing unit to provide extraordinary tones peculiar to a message-absent call, a message-present call, and a repeat call for repeatedly displaying a prior message. The processed signal also appears to provide extraordinary visual displays unique to the message-absent call. When the pager receiver has a plurality of preassigned call numbers, the processed signal is produced to provide such extraordinary displays inherent to each of the respective preassigned call numbers. In addition to the extraordinary displays of the preassigned call number, a plurality of messages are successively stored in a memory in a predetermined order to be successively displayed one by one. On reception of the repeat call, the predetermined order may be changed to keep the message related to the repeat call from being erasing from the memory even when the memory is full of message.
    • 用于承载呼叫号码和/或消息的无线电呼叫信号的寻呼机接收机包括用于产生驱动器和信息信号的处理单元,以产生与呼叫号码相关的普通音调或音调,并提供表示该消息的普通视觉显示 , 分别。 经处理的信号由处理单元产生,以提供无消息呼叫特有的特殊音调,消息呈现呼叫和重复显示先前消息的重复呼叫。 处理的信号也似乎提供了无消息通话特有的非凡视觉显示。 当寻呼机接收机具有多个预先分配的呼叫号码时,产生处理的信号以提供每个相应的预分配呼叫号码固有的这种非凡的显示。 除了预先分配的呼叫号码的非常显示之外,多个消息以预定顺序连续存储在存储器中,以逐个连续显示。 在接收到重复呼叫时,即使当存储器充满消息时,也可以改变预定顺序以保持与重复呼叫相关的消息从存储器擦除。

    • A battery saving circuit for use in a portable radio communication apparatus adapted to receive a communication signal which includes a preamble and identification codes. The apparatus includes a receiver section, a waveform shaper section, a decoder section and a power supply. The battery saving circuit, forming a portion of the decoder section, periodically generates a first control signal which causes the power supply to be electrically connected to the receiver and waveform shaper sections. A second control signal is generated to disconnect the receiver and waveform shaper sections from the power supply when, during an assigned time period, the preamble code is not detected. A third control signal is generated to maintain electrical connection between the power supply and the receiver and waveform shaper sections for a selected period of time after the preamble is detected.
