Pager receiver for enabling to omit power-on signal for receiving synchronization code in pager signal

A pager receiver for receiving a pager signal having a predetermined baud rate, said pager signal comprising a preamble signal and one or more batch signals succeeding the preamble signal, each of the batch signals comprising a synchronization code signal and a plurality of address signals succeeding the synchronization code signal, each of the address signals comprising a call number signal and a message signal, a particular one of the address signals being assigned to the pager receiver, said pager receiver comprising:

• receiving means for receiving said pager signal to produce a received signal at power-on signals of a battery saving signal;
• baud rate monitoring means coupled to said receiving means for monitoring a baud rate of said received signal to produce a monitored signal when said baud rate is equal to said predetermined baud rate;
• preamble detection means coupled to the receiving means for detecting said preamble signal in said received signal to produce a preamble detection signal;
• synchronization code detection means coupled to said receiving means for detecting said synchronization code signal in each of said batch signals of the received signal to produce a synchronization detection signal;
• generating means coupled to said baud rate monitoring means, said preamble detection means and said synchronization code detection means for generating one of power-on signals during a time period from reception of one of said monitoring signal and said preamble detection signal to first reception of said synchronization detection signal;
• reference clock means for generating a reference clock signal;
• particular address timing decision circuit coupled to said synchronization code detection means and reference clock means for deciding a timing for receiving said particular address signal on the basis of the synchronization detection signal and said reference clock signal to produce a particular address timing signal, said particular address timing signal being supplied to said receiving means as one of the power-on signal of said battery saving signal;
• deriving means coupled to said receiving means for deriving said message signal from said received signal as a derived message signal;
• memorizing means for memorizing a particular call number assigned to said pager receiver;
• call number comparing means coupled to said particular address timing decision circuit, said receiving means, and said memorizing means for comparing said call number represented by said call number in said particular address signal in said received signal and said particular call number to produce a coincident signal when said call number in said particular address signal and said particular call number are coincident with each other;
• deciding means coupled with said baud rate monitoring means and said call number comparing means for deciding whether or not both of said monitored signal and said coincident signal are present to produce an acceptance signal when said both of said monitored signal and said coincident signal are present;
• and
• processing means coupled to said deciding means and said deriving means responsive to said acceptance signal for taking said derived message signal thereinto.
