Abstract

PURPOSE:To prevent trouble to surrounding persons and overhearing by varying an automatic stop time of a notice tone in interlocking with a switch selecting the quantity of the notice tone. CONSTITUTION:An output level of a notice tone is set to a mode setting 5 in a logic section by switches 0FF6, A7, and B8. The switches 6-8 are switches of pushbutton type or slide type and operated by a carrier of a slave set. With the switch A7 set to ON, a large sound output of the mode setting 5 is valid, a timer 9 is operated and a notice tone signal for 10sec is outputted to a speaker 13 as a large output level via an output adjustment section 11. On the other hand, with the switch B set to ON, a small sound output of the mode setting is valid, a timer 10 is operated and a notice signal for 30sec is outputted to the speaker 13 as a small output level. Thus, when the sound is large, the sound is quickly stopped automatically to prevent trouble and when the level with a small notice tone is selected, the automatic stop time is extended to prevent overhearing.

BACKGROUND OF THE INVENTION 1. Field of the Invention This invention relates to wireless local paging systems for selective personal calls.

0002

2. Description of the Related Art A conventional wireless local paging system for selectively calling individuals consists of a stationary base unit equipped with a wireless transmitter and a portable slave unit equipped with a wireless receiver.
This is a wireless paging device that can selectively call multiple handsets. Generally, in order to notify the bearer that there is a call, the device is equipped with a sound means such as a buzzer, and a light notification means such as a blinking lamp. The volume of this notification sound can be selected from high to low. If you set the volume to high here and leave your seat for urgent business without taking your handset with you, when a call occurs, a notification tone will sound, so the ringing will automatically stop. There is. In addition, the advantage of the automatic stop function is that it can stop the notification sound without operating the handset, and it can quickly start the next operation after the notification operation, which saves power consumption. There are things you can do. However, depending on the size of the notification sound, the automatic stop time of the sound does not change, either by a fixed method, or without an automatic stop function.

0003

[Problems to be Solved by the Invention] However, if the person in question is away from the handset, he or she may not notice the ringing notification sound, which may cause trouble to unrelated people nearby. Therefore, the handset measures the time since the notification was made and stops the notification sound when a predetermined period of time has elapsed, without the user having to make any special switch operations. At this time, if the notification sound is too loud, it may annoy unrelated people, so there is a function to automatically stop the notification sound, but on the other hand, if the notification sound is low, people tend to notice it late, so the notification sound may be turned off. If the automatic stop time is short, there is a fear that the calling function may not be activated.

0004

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a selectively callable wireless premises paging system that is linked to a slide switch (hereinafter referred to as a switch) that selects the level of notification sound. The automatic stop time of the notification sound can now be changed. Therefore, when either high or low notification sound is selected by the switch, if the notification sound is high, the notification sound automatic stop time will be relatively short, for example, 10 seconds, and if the notification sound is low, the notification sound will stop automatically. The automatic sound stop time was made longer, for example, 30 seconds.

[0005]

[Operation] In the selective calling system configured as described above, when the notification tone volume is selected by the switch, and a calling signal is received and the calling code matches, the calling notification is started.
The output level of the notification sound at this time is high, and a loud sound is emitted from the speaker.The notification sound automatic stop timer at this time is 10 seconds, so it is 10 seconds from the start of the sound.
If the stop switch is not pressed within 10 seconds, it will automatically stop after 10 seconds. Similarly, when the low notification sound is selected and the call codes match, the output level of the notification sound becomes low, and a low sound is emitted from the speaker. If the ringing switch is not pressed within 30 seconds after the ringing starts, the ringer will automatically stop after 30 seconds.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below with reference to the drawings. In FIG. 1, a radio receiving section 1 demodulates radio waves received from an antenna 2 and outputs a signal to a coincidence determining section 3. The call code from the IDROM 4 is output to the match determination section 3 and compared with the demodulated signal. If the comparison results in a match, it is output to the mode setting 5 in the logic section. Here, a mode setting means is constituted by a switch OFF6, a switch A7, a switch B8, and a mode setting 5. The switch is a push button type switch, a slide type switch, etc., and is operated by the wearer. Assuming that initial settings have been made with switch OFF6, switch A7, and switch B8, for example, if switch A is "on", only the volume output of mode setting 5 is valid. The loud signal and the small sound signal of mode setting 5 are connected to timer A9, timer B10, and output adjustment section 11, respectively. The clock output of clock 12 is connected to timer A9 and timer B10, respectively.

[0007] Here, the timer A9 and timer B10 constitute time axis setting means for the notification sound. The outputs of timer A9 and timer B10 are connected to output adjustment section 11. Here, the output adjustment section 11 constitutes an output level control means. In this way, when the loud output in mode setting 5 is valid, only timer A operates and outputs a 10-second notification sound signal to the output adjustment section 11. The output adjustment section 11 outputs an output with a high output level to the speaker 13.

On the other hand, when switch B is "on", only the low volume output of mode setting 5 is enabled, timer B10 is activated, and a 30 second notification signal is output to output adjustment section 11. The output adjustment section 11 outputs an output with a low output level to the speaker 13.

[0009]

[Effects of the Invention] As explained above, the automatic stop time of the notification sound is changed in conjunction with the setting of the notification sound volume, so even if the handset is left behind and a call is made, If there is a loud noise that is a nuisance, it will automatically stop immediately. Furthermore, if a low level of notification sound was selected, the automatic stop time was lengthened because recognition of the call would be delayed. In this way, it is possible to prevent missed calls.
