Abstract

PROBLEM TO BE SOLVED: To provide a method capable of easily searching a left article and a left article searching machine, since it frequently occurs that a person forgets where a personal belonging placed just for a moment is put with advancing age in daily life. SOLUTION: The article searching machine is constituted of a transmitter (a) which can sequentially oscillate a plurality of radio waves whose frequencies can be converted and a plurality of receivers (b) receiving the frequencies. The receivers (b) can be made small and light. A plurality of left articles are sequentially searched.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a misplaced article search method and an article searcher which are composed of a transmitter and a plurality of small and lightweight receivers and which can be attached to an article which is likely to be misplaced and can be searched by radio waves. .

[0002]

2. Description of the Related Art Conventionally, there is a thing-for-lost device, which consists of a parent device and a child device that use radio waves. The child device is attached to an object and the parent device is placed on the object and When the distance was over a certain distance, the buzzer of the parent device began to sound, indicating that you had forgotten something.

[0003]

However, since this kind of thing has a pair of forgotten thing preventers, it can only be used for one thing. In addition, the weight of the child device increased and it is suitable for large bags, etc., but it was inconvenient for searching because it was attached to small items such as glasses, wallets and keys. Furthermore, since there is no reaction unless the parent device and the child device are brought close to each other within a certain distance, there is a defect that it is difficult to search for an article that has been left behind. Therefore, according to the present invention, by making the receiver small and lightweight, it is convenient to carry and install, and one or more personal belongings that have been left behind can be sequentially searched.

[0004]

SUMMARY OF THE INVENTION The present invention provides a transmitter capable of sequentially transmitting radio waves capable of converting a plurality of frequencies by a switch operation, and an individual receiver capable of receiving the plurality of frequencies having a small size and a light weight. Easy to install, attach to personal items that may be left behind,
Reacting the receiver by transmitting the radio wave of the transmitter even from a remote place, healthy people are originally intended for physically handicapped people especially deaf people, blind people, misplaced personal belongings The feature is that the receiver can be remarkably small and light in weight.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a perspective view of a transmitter a and a receiver b according to the present invention. The main body 1 of the transmitter a is provided with conversion switches 2 for searching and frequency conversion, ... In addition to displaying the entered characters 2a and Braille 2b, a return switch 3 in Braille display, a pilot lamp 4 and an antenna 5 interlocked with the return switch 3 are provided, and the main body 1 is provided with a battery holder 6 and a power cord 7. is there.

The receiver b includes a voice generating unit 11 and a light generating unit 1.
2, a vibration generator 13 and a button battery holder 14 are provided. Further, the voice generating unit 11, the light generating unit 12, and the vibration generating unit 13 may be provided by combining one or two of them.

FIG. 2 shows an embodiment in which the metal type receiver b-1 is attached to the spectacle case 15.

FIG. 3 shows a card type receiver b-2 as a wallet 16
It is an example attached to.

FIG. 4 shows a key holder type receiver b-3 key 17
It is an example attached to.

FIG. 5 shows a batch type receiver b-4 with a cap 18
It is an example attached to.

FIG. 6 is a block diagram of a transmitter according to the present invention, which includes a signal transmission section 21, a frequency conversion transmission section 22, and a modulation section 2.
3, a high-frequency amplifier 24, an antenna 25, and a power supply 26 including an AC or a battery are provided. Furthermore, the signal transmission unit 21
And the frequency conversion transmitter 22 are conversion switches 2, 2, ...
The interlocking operation is performed by.

FIG. 7 is a block diagram of a receiver according to the present invention, which includes a radio wave receiving section 31, a detecting section 32, a signal wave amplifying section 33, a voice generating section 11, a light generating section 12, a vibration generating section 13, and a power standby battery. A section 34 is provided.

The transmitter main body 1 is installed at a predetermined place such as a desk, the receiver b is attached to a necessary article that should not be left behind, and the receiver b can be installed by simply pressing the conversion switch 2 for searching the transmitter name. It reacts immediately and can be searched easily. Especially when the person is old, it is difficult to find what he / she put, and it takes time to find it, and he sometimes gives up because he cannot find it. However, when the present invention is used, such a thing disappears.

[0014]

EFFECTS OF THE INVENTION Since Braille is also used for the conversion switch of the search name of the transmitter, and the receiver is notified by voice, light emission, or vibration, it can be used by persons with disabilities. If a transmitter is placed near a person who cannot move due to illness or old age and a receiver is attached to a healthy person, it can be used for calling and is very convenient for nursing care. In this case, the receiver is made of plastic and uses an extremely lightweight member, so that the receiver does not feel heavy even if it is attached to the object to be searched. All of the ultra-small and lightweight receivers are extremely convenient to install and carry and easy to handle.
