A radio pager system includes a radio pager that can receive messages and can specify a specific output mode, including a display, a sound output, a vibration, and a light emission appropriate to a particular type of message. The radio pager can further reduce difficulties in retransmitting and/or replying to messages and save time in the transmission period. The radio pager can receive and implement a radio message that includes control information which can be utilized for generating the specific output mode of the display.

Radio-calling device capable of setting flexibly output mode

An amplifier circuit unit is composed of an offset compensation circuit for equalizing and issuing a DC potential in data input period of one input signal of differential input signals, and a DC potential in data input period of other input signal, and an amplitude limiting amplifier circuit for receiving a differential output signal from this offset compensation circuit as an input signal, and issuing to a differential output terminal as a differential output signal kept in a constant output signal amplitude while amplifying in a linear region. This amplifier circuit unit is connected in cascade in plural stages as required, and is applied to an amplifier circuit of an optical receiving circuit and others.

A method and apparatus for transmitting code data of a multi-color subject copy from a transmitter to a receiver in a manner that minimizes the volume of code data. The form of the data is determined by the capabilities of the receiver. The original images consist of at least two colors in addition to the background color of the copy sheet. A transmitter scans each line of the copy sheet to develop scan signals corresponding to the original images. The scan signals are used to prepare sets of run length code data and color discrimination code data indicative of the colors which appear in each line of the subject copy sheet. The transmitter transmits color discrimination code data and the corresponding set of run length code data to a receiver adapted to reproduce the transmitted data. The method of combining the scan signals to create the transmitted image signals and color discrimination code produce a condensed data strength.
