Abstract

PURPOSE:To improve the sensitivity of a beeper without remodeling the beeper body by receiving a signal from a transmitting station, amplifying the received signal, sending the amplified signal to the beeper, and operating the beeper. CONSTITUTION:The signal sent from a transmitting antenna 2 of a transmitting means of a transmitting station 1 by a radio wave 3 is received by a receiving antenna 5 of the receiving means of a reception sensitivity improving device 4, an the weak signal is amplified by an amplifier 6 of an amplifying means. The signal amplified by the amplifier 6 is sent to a transmitting antenna 8 of the transmitting means of the improving device 4 and sent from the transmitting antenna 8 to a receiving antenna 11 of the receiving means of a beeper 10 by a radio wave 9. The beeper 10 receives the above-mentioned signal and is made into an operating state. The above-mentioned improving device 4 has a container body 12 to house the beeper 10, the receiving antenna 5 is provided for its back face 13, the transmitting antenna 8, the amplifier 6, and a battery 7 are incorporated in the body 12, and the battery 7 can be taken in and out from the part of a cover 14 of the body.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for improving the reception sensitivity of a pager.

[Conventional technology]

Recently, the demand for pagers has increased rapidly due to their convenience and low usage fees. The performance of a pager is determined by its reception sensitivity. In other words, a pager that can receive signals even when far away from a radio wave transmitting station has high performance. Efforts are being made to improve the reception sensitivity of high-performance pagers, as this increases the service area and benefits the users. However, improvements in reception sensitivity of pagers are currently reaching their limits due to structural and circuit technology issues.

[Problem to be solved by the invention]

The present invention attempts to improve the sensitivity of a pager without being subject to the limitations of the pager structure and circuit technology and without making any modifications to the pager body.

[Means to solve the problem]

In view of the above, the present invention is configured to receive and amplify a signal from a transmitting station, and send the amplified signal to a pager to operate the pager.

〔Example〕

Embodiments of the present invention will be specifically described below with reference to the drawings.

The signal sent by radio waves (3) from the transmitting antenna +2) of the transmitting means of the transmitting station (1) is transmitted to the receiving sensitivity improving device (4).

receive from The signal amplified by the amplifier (6) is sent to the transmitting antenna (8) of the transmitting means of the improvement device (4), and from the transmitting antenna (8) is sent by radio wave (9) to the receiving antenna αυ of the receiving means of the pager αG. . Pager αO is
It becomes operational upon receiving the above signal.

The improvement device (4) has a container body α2 that can accommodate a pager αO, and a receiving antenna (5) on its back side 03.
A transmitting antenna (8) and an amplifier (
6), a battery (7) is installed, and the battery (7) can be taken in and out from the lid αψ of the main body.

The improving device (4) enters a single oscillation state when its receiving antenna (5) and transmitting antenna (8) are electromagnetically interfered. In order to prevent electromagnetic interference between both antennas (5) and (8), the transmitting antenna (
8) is surrounded by a shielding body αQ made of a metal material for electromagnetic shielding.

〔Effect of the invention〕

In the present invention, with the above configuration, the pager σa is separated from the improvement device (4) and can be received in a narrow area (A
), and in a wide area (B) where the pager cannot be received by itself, the pager 00 can be stored in the improved device (4) and can be used for reception, which is convenient. Furthermore, even in a narrow area (A), there may be cases where the pager αG cannot receive data by itself in a car, and in that case, the improvement device (4) can be used to use the pager. In this manner, the present invention can improve the sensitivity of a pager without being subject to the limitations of the structure and circuit technology of the pager, and without making any modifications to the pager body.
