Abstract
Abstract In a multifunctional pager receiver comprising a processing circuit (30) operable in a plurality of modes of operations, each mode is selected by manual switches (51, 62-64) smaller in number than the modes. A combination of successive manual operations of the switches changes the modes from an intermediate one to a final one. At least one of the switches is operated plural times. An operation announcement is stored in a message processor (32) included in the processing circuit and displayed in the intermediate mode on a display unit (71) so as to specify the following modes to be selected. A plurality of message signals are stored in a random access memory included in the message processor. A part of each stored message is successively and rapidly displayed on the display unit. A decoder cooperates with the message processor in the processing circuit to detect a call number signal assigned to the pager receiver and delivers a sequence of clocks to the message processor.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
154 words
A pager receiver comprising a display unit for displaying each message carried by message signals, said pager receiver comprising: manually operable specifying means for specifying a plurality of manual modes, one after another at a time, to produce a mode signal indicative of each of said manual modes; a memory unit for memorizing a plurality of announcement signals representative of operation announcements, respectively, said operation announcements corresponding to the respective manual modes, each of said operation announcements being indicative of at least one of said manual modes that should be specified following the manual mode indicated by said mode signal; and accessing means coupled to said specifying means and to said display unit for accessing said memory unit in response to said mode signal to send one of said announcement signals to said display unit as an active signal and to make said display unit display the operation announcement represented by said active signal.
Claim 2
Dependent Claim
154 words
A pager receiver comprising a display unit for displaying each message carried by message signals, said pager receiver comprising: manually operable specifying means for specifying a plurality of manual modes, one after another at a time, to produce a mode signal indicative of each of said manual modes; a memory unit for memorizing a plurality of announcement signals representative of operation announcements, respectively, said operation announcements corresponding to the respective manual modes, each of said operation announcements being indicative of at least one of said manual modes that should be specified following the manual mode indicated by said mode signal; and accessing means coupled to said specifying means and to said display unit for accessing said memory unit in response to said mode signal to send one of said announcement signals to said display unit as an active signal and to make said display unit display the operation announcement represented by said active signal.
Claim 3
Dependent Claim
90 words
A pager receiver as claimed in Claim 1, wherein said mode specifying means comprises: a manual operable switch responsive to a first one of said manual operations for producing a first one of said mode signals representative of a first one (Claim 2 continued) of said manual modes and further responsive to a second one of said manual operations following said first manual operation for producing a second one of said mode signals that is representative of a second one of said manual modes different from said first manual mode.
Claim 4
Dependent Claim
198 words
A pager receiver as claimed in Claim 1 or 2, each of said message signals being divisible into a plurality of parts arranged from a leading part to a trailing one, said pager receiver comprising storage means for storing said parts of each message signal, wherein said mode specifying means comprises: first means for producing a first specific one of said mode signals that specifies a first specific one of said manual modes when said first means is manually operated; and second means for producing a second specific one of said mode signals that specifies a second specific one of said manual modes when said second means is manually operated; said pager receiver further comprising: first readout means responsive to said first specific mode signal and coupled to said storage means for successively reading each leading part of said message signals out of said storage means to make said display unit successively display said each leading part; and second readout means responsive to said second specific mode signal and coupled to said first readout (Claim 3 continued) means for reading the remaining parts of the message of which the leading part is being displayed on said display unit.
Claim 5
Dependent Claim
74 words
A pager receiver as claimed in Claim 3, said pager receiver comprising a power source detachable from said storage means for delivering a source voltage to said storage means when said power source is connected to said storage means, said pager receiver further comprising: capacitor means connected to said power source and said storage means for supplying an electric voltage to said storage means when said power source is detached from said storage means.
Claim 6
Dependent Claim
167 words
A pager receiver as claimed in any of'claims 1 to 4, said pager receiver being operable in response to a call signal comprising a call number signal assigned to said pager receiver and a message signal which follows said call number signal and carries each of said messages, said receiver further comprising: clock generating means for generating a sequence of oscillation pulses having a predetermined oscillation frequency; clock pulse producing means responsive to said oscillation pulses for producing a first and a second sequence of clock pulses which have a first predetermined frequency and a second predetermined frequency different from said first predetermined frequency, respectively, (Claim 5 continued) said first and said second predetermined frequencies being lower than said predetermined oscillation frequency; detection means responsive to said first clock pulses and said call signal for detecting said call number signal; and delivering means for delivering said second clock pulses to said access means to put said accessing means into operation in accordance with said second clock pulses.
Claim 7
Dependent Claim
196 words
A pager receiver comprising a memory unit storing each message signal which is representative of a message and which is divisible into a plurality of parts arranged from a leading part to a trailing one and a display unit for displaying said message, wherein the improvement comprises: mode specifying means energized by each of manual operations for specifying a first specific mode in response to a first one of said manual operations to produce a first specific mode signal representative of said first specific mode and for specifying a second specific mode in response to a second one of said manual operations following said first manual operation to produce a second specific mode signal representative of said second specific mode; first readout means responsive to said first specific mode signal .for successively reading each leading part of said messages out of said memory means to make (Claim 6 continued) said display unit successively display said each leading part; and second readout means responsive to said second specific mode signal and coupled to said first readout means for reading the remaining parts of the message of which the leading part is being displayed on said display unit.
