Abstract
Abstract A radio paging receiver which generates an alert tone and a message display on receipt of a selective calling signal, includes a manually operated non-lock type switch which generates first and second control signals. The first control signal stops the generation of the alert tone while the second control signal initiates a time-out period after which the displayed message is turned off. Depressing the switch produces the first control signal while its release produces the second control signal.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
190 words
A radio paging receiver having a display means and a switch which can be selectively activated and released, said receiver comprising: a first means for detecting a selective calling signal assigned to said receiver; a second means for receiving and storing a message transmitted subsequently to said selective calling signal; a third means for generating an alert tone in response to the detection of said selective calling signal; a fourth means for displaying the message stored in said second means on said display means in response to the reception of said message; a fifth means for stopping the generation of said alert tone and the display of said message after a first predetermined period of time has elapsed; a sixth means for stopping the generation of said alert tone when said switch is activated within said first predetermined period of time; a seventh means for stopping the display of said message after a second predetermined period of time that starts from the release of the activated switch; and an eighth means for stopping the display of said message when said switch is activated within said second predetermined period of time.
Claim 2
Dependent Claim
190 words
A radio paging receiver having a display means and a switch which can be selectively activated and released, said receiver comprising: a first means for detecting a selective calling signal assigned to said receiver; a second means for receiving and storing a message transmitted subsequently to said selective calling signal; a third means for generating an alert tone in response to the detection of said selective calling signal; a fourth means for displaying the message stored in said second means on said display means in response to the reception of said message; a fifth means for stopping the generation of said alert tone and the display of said message after a first predetermined period of time has elapsed; a sixth means for stopping the generation of said alert tone when said switch is activated within said first predetermined period of time; a seventh means for stopping the display of said message after a second predetermined period of time that starts from the release of the activated switch; and an eighth means for stopping the display of said message when said switch is activated within said second predetermined period of time.
Claim 3
Dependent Claim
72 words
A radio paging receiver, as claimed in claim 1, further comprising: a ninth means for displaying all the stored messages from the latest one to the oldest when said switch is repeatedly activated while said receiver stands ready for receiving a selective calling signal thereto; and a tenth means for stopping the display by said ninth means after a third predetermined period of time that starts from the release of said switch.
Claim 4
Dependent Claim
23 words
A radio paging receiver, as claimed in claim 2, wherein said first through third predetermined periods of time are of the same length.
Claim 5
Dependent Claim
18 words
A radio paging receiver, as claimed in claim 3, wherein said same length of time is 8 seconds.
Claim 6
Dependent Claim
17 words
A radio paging receiver, as claimed in claim 1, wherein said switch is a non-lock type push-switch.
Claim 7
Independent Claim
105 words
A method for displaying a message on the display means of a paging receiver, comprising the following steps; a. detecting a selective calling signal followed by said message and assigned to said paging receiver; b. generating an alert tone in response to the detection of said selective calling signal; c. receiving and storing said message; d. displaying the stored message; e. stopping the generation of said alert tone in response to the activation of a switch included in said paging receiver; and f. stopping the display of said message after a first preset period of time that starts from the release of the activated switch.
Claim 8
Independent Claim
105 words
A method for displaying a message on the display means of a paging receiver, comprising the following steps; a. detecting a selective calling signal followed by said message and assigned to said paging receiver; b. generating an alert tone in response to the detection of said selective calling signal; c. receiving and storing said message; d. displaying the stored message; e. stopping the generation of said alert tone in response to the activation of a switch included in said paging receiver; and f. stopping the display of said message after a first preset period of time that starts from the release of the activated switch.
