Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable small radio selective calling receiver called a pager, a pager, or the like, and more particularly, it has a security bell function and operates the security bell function. The present invention relates to a radio selective calling receiver in which time is stored and stored in a memory.

[0002]

2. Description of the Related Art There are radio selective call receivers having various functions. For example, when a call signal is received by radio, a sounder such as a buzzer or a bell sounds to notify a portable person of a call. From those, the message message is wirelessly received together with the calling signal, and the message is displayed and output on a display screen such as an LCD, or the information message such as news and weather forecast is wirelessly received together with the calling signal, and the message is LC
D and the like which are displayed and output on a display screen. As a function common to such radio selective calling receivers, the time at which a calling signal is received is stored in a memory based on timing by a timer, so that the time at which a calling signal or a message is received can be confirmed later by a wearer. It has become.

On the other hand, security bells are widely used as small electronic devices that are carried and carried by users. Generally, a security bell has a loud sounder such as a buzzer, a buzzer, and a bell, and a switch for sounding the sounding unit.
By operating the switch by the wearer, the sounding section is sounded to notify the surrounding people that some abnormal situation has occurred.

[0004]

Here, for a user who carries a radio selective call receiver and a burglar alarm, the fact that they are separate devices means that they are either bulky or used as luggage. It is inconvenient to have to search for it. In particular, although there is a strong demand for miniaturization of radio selective call receivers and security bells to enhance portability, carrying these devices separately has been improved to satisfy the demands. This is a major issue that must be addressed.

Considering the general use situation of the radio selective call receiver and the security bell, since the radio selective call receiver is used more frequently than the security bell, the radio selective call receiver is used. Is often carried in a place where it can be easily taken out, such as a jacket pocket. However, it is important to be able to take out the security bell quickly, when it occurs, and to alert the surrounding people of the occurrence of the abnormal situation by using a ringing sound. It is required to use it in a state where it is easily taken out on a daily basis in the same manner as in the above. In addition,
In a security bell, it is desired to record the notification time of an abnormal situation for a purpose different from that of the selective radio call receiver.

The present invention has been made in view of the above-mentioned conventional circumstances, and rationally combines the function of a radio selective call receiver and the function of a security bell to provide a radio selective call receiver and a security bell. It is an object of the present invention to provide a radio selective calling receiver which is convenient and satisfies required functions.

[0007]

SUMMARY OF THE INVENTION The present invention is applied to a portable small-sized radio selective call receiver which stores a call reception time at which a simple call or a message is received in a memory based on time counting by a timer. The selective call receiver is provided with a security bell function using the function. In other words, when the user operates the security bell switch, the alarm sounds to notify the surrounding person that some abnormality has occurred, and the control unit operates the security bell switch based on timing by a timer. The time is stored in the memory. By integrating the radio selective call receiver and the security bell in this way, it is possible to satisfy the common demand of both being stored and carried in an easy-to-remove place,
By utilizing the timekeeping function of the radio selective calling receiver, a function of recording the notification time, which is a request unique to the security bell, is also realized.

The memory for recording the notification time of the abnormal situation can be used in common with the memory for recording the call reception time and the reception message. However, even if the battery power is exhausted or lost, the notification is performed. It is preferable to use a non-volatile memory so that the time can be stored. Further, since the radio selective calling receiver of the present invention is carried, a primary battery or a rechargeable secondary battery is used as a power source, but the power receiving characteristics required for the call receiving function and the security bell function are not satisfied. There are differences. In other words, it is preferable that the call receiving function be able to withstand long-term use even at a low voltage in order to achieve long-term reception, while the security bell function has a short time because it emits a loud sound. However, a high voltage is preferred. In the present invention, it is of course possible to use a power battery for both the call receiving function and the security bell function, but it is preferable to provide a power battery for each of the call receiving function and the security bell function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A radio selective call receiver according to the present invention will be specifically described based on one embodiment. FIG.
FIG. 2 shows the configuration of the radio selective calling receiver according to the present embodiment, and FIG. 2 shows its operation in the form of a flowchart. The radio selective call receiver 1 sounds by a switch operation of a wearer, together with a simple call operation based on reception of a call signal and a call reception function of a message display operation of displaying and outputting a message wirelessly received together with the call signal. It has a security bell function.

First, as a part related to the call receiving function,
The radio selective calling receiver 1 includes an RF unit 3 for receiving a radio signal via an antenna 2, a decoder 4 for decoding the received signal, a timer 5 for internally measuring time, a call number assigned to itself, ROM 6 that stores a program for performing a predetermined operation, RAM 7 that stores a call reception / reception message and a reception time thereof, a display 8 composed of an LCD that displays and outputs the reception message, and notifies the reception of the call and the reception of the message. A sound section 9 such as a buzzer, a switch operation section 10 for accepting an operation related to a call receiving function such as displaying a message or stopping a sound from a carrier, a ROM 6.
And a power supply battery 12 for supplying operating power to the function units 1 to 11 related to the call reception by executing a program stored in the control unit 11 to control the function units 3 to 10 collectively. I have.

Further, as a part relating to the security bell function,
The radio selective call receiver 1 accepts from a person who carries out an operation for operating the ringing unit 13 for a security bell such as a buzzer that emits a loud alarm compared with the sounding unit 9 of the call receiving function, and an operation for operating the ringing unit 13. It includes a security bell switch operation unit 14, a security bell power supply battery 15 for supplying operating power to the sounding unit 13, and an EE-PROM 16 for storing the time when the security bell switch operation unit 14 is operated and the sounding unit 13 is operated. . Here, the timer 5 and the control unit 11 are also used for the security bell function, and the control unit 11 controls the operation of the sounding unit 13 based on the operation of the switch operation unit 14 and the time when the sounding unit 13 operates. A process of writing (operation time of the security bell switch 14) into the EE-PROM 16 based on the time measured by the timer 5 is performed.

In the present embodiment, the nonvolatile memory 16 for storing the operation time of the security bell switch 14 is E.
Although an E-PROM is used, another nonvolatile memory such as an E-PROM can be used as long as it is writable and can retain stored contents even when power supply is cut off. Further, in the present embodiment, a pin-type switch for operating the alarm ring 13 for the security bell by pulling out the pin is used as the security bell switch 14, but this switch type is not particularly limited in the present invention.

The operation of the radio selective receiver 1 having the above configuration will be described with reference to FIG. First, the radio selective receiver 1
When the power switch is turned on, a call reception process of waiting for reception and a reception operation is performed using the power from the power supply battery 12 for call reception (step S1). That is, when the call signal wirelessly received through the antenna 2, the RF unit 3, and the decoder 4 matches the own call number stored in the ROM 6, the control unit 11 operates the ringing unit 9 to call the call. Notification, writing and storing of the received message in the RAM 7, recording of the call receiving time based on the time measured by the timer 5 in the RAM 7, and the like are performed.

If the security bell switch 14 is operated (step S2) even during such a call reception process, the control unit 11 causes the timer 5 to count the current time. The reading is performed (step S3), and the time is written and recorded in the EE-PROM 16 (step S3).
4) The security bell ringing unit 13 is operated by the power of the security bell power supply battery 15 to notify the occurrence of an abnormality (step S5). If the security bell switch 14 is turned off (in this example, the switch pin is returned) (step S6), the control unit 11 causes the security bell ringing unit 1 to operate.
The operation of Step 3 is stopped (Step S7), and the process returns to the normal call receiving process as described above.

Therefore, the operation time of the security bell switch 14 is recorded in the non-volatile memory 16 by using the time of the timer 5, and this operation is also performed by turning off the security bell switch 14 or cutting off the power from the power batteries 12 and 15. The recording time is saved. Here, since the radio selective calling receiver in recent years has a function of receiving time information together with, for example, an information message and correcting the internal timer clock, the radio selective calling receiver performs such time correction. If it has the function, the time recorded in the nonvolatile memory 16 is extremely accurate. The recorded time can be read out by taking out the volatile memory 16 from the receiver 1 and using a separately prepared memory reader.
The radio selective calling receiver 1 may be provided with a function of reading the time stored in the volatile memory 16 and displaying the time on the display 8.

[0016]

As described above, according to the present invention,
The wireless selection receiver effectively utilizes its inherent function, and also has a security bell function that can record and save security alarm time, so that it is easy to use and satisfies the required functions. It is possible to realize a radio selective call receiver with a burglar alarm function.
