Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio call terminal device having a crime prevention alarm function.

[0002]

2. Description of the Related Art A crime prevention buzzer which emits an alarm sound by operating a plug or a switch in an emergency has been widely used for the purpose of preventing danger and preventing molesting. Also,
As disclosed in Japanese Patent Application Laid-Open No. 58-54496, there is a portable audio device (radio receiver or the like) to which an alarm sound generating function is added. According to this publication, an alarm sound is emitted via a switch that is opened and closed by a plug that can be inserted and removed from the outside of the case.

[0003]

In the above-described conventional crime prevention buzzer and portable audio equipment, an alarm sound is emitted by operating a plug or a switch. However, in an emergency, there are cases where the plug cannot be removed or the switch cannot be pressed, and in such a case, there is a problem that the original function cannot be exhibited.

An object of the present invention is to provide a radio paging terminal device with a crime prevention alarm function which can operate the alarm function even when the plug or switch cannot be operated.

[0005]

SUMMARY OF THE INVENTION A radio call terminal device with a crime prevention alarm function of the present invention comprises a buzzer driving means for driving a buzzer to generate a sound, and a buzzer driving means connected to a power source for insertion. A plug switch that is turned on and off by attaching and detaching the plug, and a seismic switch that is connected in parallel to the plug switch to detect acceleration and turn on and off, and the buzzer driving means is provided via the plug switch or the seismic switch Is configured to drive the buzzer at maximum output when connected to the power source.

[0006]

The present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention. Here, the receiving unit 1 receives the ringing signal transmitted from the base station, and when receiving a predetermined ringing signal, drives the buzzer 3 via the ringing tone generating unit 2 to notify the user of the incoming call.

Plug switch 4 and seismic switch 5
Are connected in parallel between the ringing tone generator 2 and the power supply 6. Therefore, when at least one of the switches is in the ON state, power is directly supplied to the ringing tone generating section 2 from the power source section 6. When the ringing sound generation unit 2 receives power directly from the power supply unit 6, the ringing sound generation unit 2 drives the buzzer 3 with the maximum output to generate a large alarm sound.

By the way, the plug switch 4 has an insertion plug 41 that can be inserted and removed from the outside of the case of the device. When the insertion plug 41 is inserted, it is in the OFF state, but when the insertion plug 41 is removed. Is turned on.

Further, the seismic switch 5 is a switch which operates by detecting acceleration, and is turned on when a sudden vibration or impact exceeding a preset value is received, and the reset button 51 is operated. The ON state is maintained until.

Therefore, when an alarm sound is to be issued in order to prevent danger or molesting, the wearer can pull out the plug 41 of the plug switch 4. However, even in a situation where the plug 41 cannot be pulled out, the seismic switch 5 can detect an abnormal movement or impact of the wearer and issue an alarm sound.

Further, since the ringing tone generating section 2, the buzzer 3 and the power source section 6 which function as an ordinary radio calling terminal are shared, there is no increase in size and complexity.

[0013]

As described above, according to the present invention, the operation of the insertion plug can be performed by providing the seismic switch for detecting abrupt vibration or shock in parallel with the plug switch operated by the attachment / detachment of the insertion plug. Even in situations where it is not possible, the alarm sound can be emitted by detecting abnormal movements and impacts of the wearer, so it has the effect of being able to use the alarm function even in an unexpected emergency situation and using it with confidence. There is.
