SUMMARY OF THE INVENTION For a long time,
There is a limit to how to be careful and maintain tension, and even if you are careful, it is possible to get lost in a crowded place or to forget or stolen items. It is desirable that even in the case of distraction, it is possible to prevent the occurrence of lost or forgotten objects by other methods. In order to prevent this, a master unit and a slave unit may be provided, and the slave unit may be attached to a child or an object, and when the child or the object leaves the body, the master unit may sound. However, in this case, it is necessary to carry the master unit and the slave unit independently, which is inconvenient to handle.

The present invention has been made in view of the above-mentioned problems, and can prevent theft such as a lost item, a lost child, a rub, a lay-down, etc., without possessing any special items in addition to the conventional belongings. It is an object of the present invention to provide a lost / lost device and a mobile phone.

[0005]

According to a first aspect of the present invention, there is provided a left-behind / lost device for preventing a lost object from being transmitted, in addition to a handset having an outgoing function, and a signal from the handset. The portable telephone is provided with a sensing function and a notifying function for notifying that the slave unit is separated by a predetermined distance or more.

According to a fifth aspect of the present invention, there is provided a portable telephone capable of calling a signal through a communication line, wherein the function of sensing a signal from a slave unit having a calling function different from that of a call for a call is provided, and A notification function is provided for notifying the user when the vehicle is separated by a predetermined distance or more. In this device for preventing lost or lost children and mobile phones, a signal can be emitted from a child device that is provided to a child or attached to a purse, valuables, bag, or the like. When an article such as a child or a wallet is nearby, the mobile phone senses a signal from the slave unit. When a child or an article is separated by a certain distance or more, the mobile phone performs a notification operation to that effect.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in more detail with reference to embodiments. FIG. 1 is a block diagram showing a configuration of a lost / lost device according to an embodiment of the present invention. The forgotten and lost child prevention device according to this embodiment includes a slave unit 1 having a function of transmitting radio waves, a sensing function of receiving the signal from the slave unit 1, and a notification that the respective slave units are notified when they are separated by a predetermined distance. And a master unit 2 having a function. The base unit 2 is built in the mobile phone 2a. Further, it may be attached to the surface of the mobile phone 2a.

[0008] In the case where the child device 1 and the parent device 2 prevent a lost child, the parent carries the portable telephone 2a, and the child device 1 is carried by the child.
When a child is present near the parent, the notification operation is not performed because the base unit 2 of the mobile phone 2a detects a radio signal from the child unit 1. If your child is 10 meters away from your parents,
When the radio signal from the slave 1 is no longer sensed, the master 2 performs a notification operation to notify the fact.

In order to prevent a lost item or theft,
Is attached to items such as wallets, precious metals, bags, and keys. If the owner is more than a certain distance away from the forgotten thing,
As in the case of a lost child, the base unit 2 of the mobile phone 2a performs a notification operation. In both the prevention of lost children and the prevention of forgetfulness, a plurality of slaves 1 may be provided for one mobile phone 2a having the master 2.

The notification function in the base unit 2 of the mobile phone 2a is performed by vibration of a vibration generator, sound from a speaker, buzzer light, and the like. Also, the distance between the handset 1 and the base unit 2 at which the notification is made can be arbitrarily set. FIG. 2 shows an example. Here, the display of 20 m is of course only an example. Here, every time the update key 3 of the slave unit 1 is operated once, the display of the display unit 4 is changed to 5, 10, 1
5, 20, ..., and when setting key 5 is turned on,
The display on the display 4 is set as the predetermined distance.

[0011] Vibration, sound, light, and the like for notification may be provided with any one of them, but they may be selectively designated. FIG. 3 shows a configuration example of the master unit 2 for that purpose. The base unit 2 includes a receiver 21 and a CPU 22
And a setting device 23 for setting a type and a distance, and a vibration generator 2
4, an audio ROM 25, a speaker 26, and a light emitter 27
And The detection distance may be set on the parent device 2 side for each child device to be used.

The shape of the base unit 2 is not particularly limited. However, if it is a card type, it can be carried and mounted anywhere without being bulky. Further, a sound may be emitted when the slave 1 is separated from the master 2. The location of the child device 1 distant from the parent device 2 can be clearly known. As another embodiment of the present invention, a portable telephone, such as a portable telephone, a portable calling device, a portable character telephone, or the like, to which the function of the parent device in FIG. 1 is added is used. These mobile phones are
It has the function of receiving calls for calls through the communication line at all times, but it also receives radio signals from child devices carried by children or attached to personal belongings. When the user moves away, the calling speaker, the vibration generator, and the like operate to notify the user.

In the portable telephone of this embodiment, parts such as a vibration generator, a speaker, a voice ROM, and a light emitting device for a telephone call can be shared, and parts can be saved. Also, if a signal indicating the type of the slave unit is transmitted from the slave unit, the display unit 32 of the mobile phone 31 displays “valuable items” and “stray items” so as to display a lost child as an example in FIG. , "Child" and the like can be displayed individually.

It is to be noted that an ultra-small IC chip that emits radio waves using an external radio wave as a power source may be used as each slave unit used in the above embodiment. Since batteries are not used, they can be used semi-permanently, and battery replacement is limited to mobile phones. In addition, the child device may be attached to a pendant, an amulet bag, a key ring, a card, or the like. It is even better to make it waterproof.

[0015]

According to the present invention, the radio wave from the slave is detected by the portable telephone as the master, and when the slave is separated from the master by a predetermined distance or more, the fact is notified. Therefore, the child device is held by the child or attached to the belongings, and the parent device or the person possesses the parent device, so that lost children, lost items, and theft can be prevented. In addition, since the mobile phone has a function as a base unit, it is possible to prevent lost or forgotten items without possessing anything other than the mobile phone.
