ABSTRACT:
FIELD OF THE INVENTION
This invention relates to a radio paging receiver with a display auto-reset function, and relates to a method for controlling a display auto-reset function of radio paging receiver.
BACKGROUND OF THE INVENTION
Some conventional radio paging receivers have a function that when no reception of new message nor switching at operation part occurs during a given time period, the display image of liquid-crystal display can be turned off automatically to avoid consuming its battery by such a useless display image that its user does not need to look. This function is called “display auto-reset function”. In a radio paging receiver with such a display auto-reset function, when there is no reception of a new message or a switching of an operation part occurs during a given time period after the radio paging receiver enters a waiting state, the display image of liquid-crystal display can be turned off automatically by the operation of the display auto-reset function.
However, for the conventional radio paging receivers with such a display auto-reset function, since even a display image that is needed can be turned off automatically by the operation of display auto-reset function, the user may be inconvenienced. Therefore, a radio paging receiver having a function that re-displays a display image automatically turned off by the operation of display auto-reset function has been also developed. For example, prior arts about such a function of radio paging receiver are described in Japanese patent application laid-open Nos. 02-190037 (1990) and 03-046833 (1991). In the former application prior art, the content of a message displayed just before the display image is turned off by the operation of display auto-reset function can be re-displayed by the key operation for re-displaying. In the latter application prior art, the content of a message displayed just before the display image is turned off by the operation of display auto-reset function can be re-displayed by the key operation for re-displaying to be conducted within a certain time period after the turn-off of the display image.
Also, though a user who uses less frequently such a radio paging receiver may feel convenient since a useless battery consumption can be cut down to save the life of battery when the display image is turned off automatically after a certain time period after displaying a message, a heavy user who has to operate frequently the switch to re-display a turned-off image to confirm a reception message not noticed and to confirm the reception time will feel inconvenient for the display auto-reset function that automatically turns off the display image after a certain time period after displaying a message. Therefore, many of conventional radio paging receivers with the display auto-reset function are designed such that the user can set selecting the turn-on or turn-off of the display auto-reset function mode where the display auto-reset function operates.
However, such a radio paging receiver capable of selecting the turn-on or turn-off of display auto-reset function mode cannot be always convenient to its user. For example, to a user who uses it frequently during the day but does not frequently use it at night, when selecting the turn-off of display auto-reset function mode in the morning, it can be convenient during the day since the display auto-reset function more is turned off, but it must be set again to select the turn-on of display auto-reset function mode at night when the frequency of use decreases. Thus, the user needs to set selecting the turn-on or turn-off of display auto-reset function mode in the morning and evening, every day.
Accordingly, the conventional radio paging receivers with the display auto-reset function fail to satisfy the requirements of all users.
SUMMARY OF THE INVENTION
Accordingly, it is an object of the invention to provide a radio paging receiver with a display auto-reset function that can be used conveniently by users while saving the battery consumption.
Also, it is an object of the invention to provide a method for controlling a display auto-reset function of radio paging receiver so that it can be used conveniently by users while saving the battery consumption.
According to the invention, a radio paging receiver, comprises:
a display; and
means for controlling the display to be turned off automatically when no switch operation nor reception message is detected during a predetermined time period within a predetermined time zone.
According to another aspect of the invention, a radio paging-receiver with a display auto-reset function that means for displaying information including a reception message is turned off automatically when no switch operation nor reception message is detected during a predetermined time period, comprises:
a first setting means for setting a display auto-reset function mode to enable the display auto-reset function;
a second setting means for setting a time zone to enable the display auto-reset function to operate when a setting to turn on the display auto-reset function mode is selected by the first setting means; and
a control means for checking whether the detection for switch operation and reception message is conducted within the time zone or not, based on the setting information of the first and second setting means, when no switch operation nor reception message is detected during the predetermined time period, and outputting a control signal to control the power supply for the displaying means to be turned off automatically when the detection is conducted within the time zone.
According to another aspect of the invention, a radio paging receiver with a display auto-reset function that means for displaying information including a reception message is turned off automatically when no switch operation nor reception message is detected during a first predetermined time period, comprises:
a display auto-reset function mode setting means for setting the turn-on or turn-off of a display auto-reset function mode to enable the display auto-reset function;
a time zone setting means for setting a time zone to enable the display auto-reset function to operate when the display auto-reset function mode is set to turn on by the display auto-reset function mode setting means; and
a display auto-reset function mode setup and operation controlling means for controlling the display auto-reset function mode setting means and the time zone setting means to start up when setting the turn-on or turn-off of the display auto-reset function mode, determining whether the current time falls within the time zone to enable the display auto-reset function to operate while the display auto-reset function mode is set to turn on, when no switch operation nor reception message is detected during the first predetermined time period after coming to the waiting time after completing the setting by the display auto-reset function mode setting means and the time zone setting means, and outputting a control signal to control the power supply for the displaying means to be turned off automatically when the detection is conducted within the time zone.
According to another aspect of the invention, a method for controlling the display auto-reset function of a radio paging receiver with a display auto-reset function that means for displaying information including a reception message is turned off automatically when no switch operation nor reception message is detected during a first predetermined time period, the radio paging receiver comprising: a display auto-reset function mode setting means for setting the turn-on or turn-off of a display auto-reset function mode to enable the display auto-reset function; a time zone setting means for setting a time zone to enable the display auto-reset function to operate when the display auto-reset function mode is set to turn on by the display auto-reset function mode setting means; and a display auto-reset function mode setup and operation controlling means for controlling the display auto-reset function mode setting means and th
