DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device for transmitting / receiving a transmission / reception signal in a wireless manner, and more particularly to a light emitting / receiving device suitable for use in a portable telephone when transmitting / receiving a call via a wireless line. The present invention relates to an apparatus capable of visually confirming a transmission / reception state by light emission of an LED.

[0002]

2. Description of the Related Art With the widespread use of mobile phones, many accessories such as character phone cases and hand straps have been provided so that users can exhibit their individuality and distinctiveness. In particular, when an incoming call arrives, instead of generating a ringing sound, the LED is illuminated using the radio wave of the mobile phone, but with a practical function of notifying the incoming call with no sound, it is a popular product due to its fashionability Circulating.

[0003] This type of incoming light emitter emits light by rectifying an 800 MHz or 1500 MHz radio wave transmitted from an antenna, and turns on an LED. A voltage corresponding to the strength of the radio wave appears. Therefore, usually, two diodes for rectification are used and a voltage doubler rectifier circuit is assembled so that a double voltage can be obtained when the transmission power is weak. Regarding such a configuration, the registered utility model No. 30072
No. 20 and JP-A-9-298410.

[0004]

In the conventional system in which radio waves are directly rectified to emit light without batteries, as disclosed in the above-mentioned publication, red and green connected to a voltage doubler rectifier circuit are disclosed. Only the LEDs of each color, such as blue and blue, are lit, and the appearance is monotonous and easy to get tired, which is not enough to satisfy the taste of the user.

[0005] In addition, there has been proposed an LED in which each of the single-color LEDs emits light at the same time. However, only the three colors are blinked at the same time.

Accordingly, the present invention relates to a light emitting / receiving element for transmitting / receiving, which enables a user to visually confirm the transmission / reception state by light emission of an LED when a call is made via a wireless line. It is an object of the present invention to provide a light emitting / receiving device for receiving / transmitting light, which is changed to a color and which can satisfy a user's taste by changing the color without forming a single pattern.

[0007]

According to the present invention, there is provided a light emitting / receiving device at the time of transmission / reception, which emits red, green, and blue LEDs, a flash IC connected to each of the LEDs as a switching element, and A rectifying element for rectifying an electromagnetic wave at the time of transmission and reception to the flash IC and supplying a current;
These components are housed in a compact housing container, and the housing container is installed near the transmitting / receiving antenna.

Therefore, when the rectifying element rectifies the electromagnetic wave at the time of transmission and reception and supplies a current to each flash IC, red,
Flash I connected to each of the green and blue LEDs
Since C operates as a switching element, the red, green, and blue LEDs blink. However, the blinking at this time is due to an operational error inherent in each flash IC itself.
Since the switching operation does not know which one of the red, green and blue LEDs is to be turned on, irregular blinking occurs in which the blinking order cannot be predicted. In addition, the switching operation includes:
In some cases, the red, green, and blue LEDs are turned on at the same time. Depending on the combination, the LED flashes and emits light in seven colors according to the three primary colors.

Further, the housing container may be formed so as to be fitted on the top of the antenna, or may be formed so as to be mounted on the base side of the antenna, so that the light emission form can be easily changed. Furthermore, if the container is formed so as to be attached as a strap-shaped decorative body attached to the base side of the antenna, the taste can be further enhanced.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be specifically described below with reference to the drawings. FIG. 1 is a diagram showing a circuit configuration of a light emitting / receiving device 1 at the time of transmission / reception which is an embodiment of the present invention.
As shown in FIG. 1, the light emitting / receiving element 1 is a switching element on the anode side of each of the LEDs 2, 3, 4 emitting red (R), green (G), and blue (B). Flash I
The common terminals of C5, C6, and C7 are connected, and each plus terminal thereof is a rectifier Schottky diode 1.
0 is connected to the plus terminal. In addition, LED
The cathode sides of 2, 3, and 4 and the minus terminals of the flash ICs 5, 6, and 7 are commonly connected to the minus terminal of the Schottky diode 10.

FIG. 2 is a view showing a cross section of the light emitting / receiving element 1 at the time of transmission / reception configured by housing the circuit components connected in this manner in a bullet-shaped cap 11, and is configured for a portable telephone. Show things. The cap 11 is formed so as to be fitted to the distal end portion 13 of the antenna 12 of the mobile phone, and R, G, R, G, and R stored at the distal end side of the cap 11 by radio waves transmitted and received by the antenna 12. B

That is, the Schottky diode 10 as a rectifying element rectifies the radio wave at the time of transmission and reception, and
When a current is supplied to C5, C6, and C7, the flash ICs 5, 6, and 7 operate as switching elements, so that the red, green, and blue LEDs 2, 3, and 4 blink. However, the blinking at this time is a switching operation in which it is not possible to determine which of red, green, and blue LEDs is to be turned on due to an operational error inherent in each flash IC itself. Blinks regularly. Further, as the switching operation, the red, green, and blue LEDs may be turned on at the same time, and the combination blinks while changing to seven colors according to the three primary colors. Since the tip of the cap 11 is filled with a diffusing agent and exhibits a lens function, the blinking light emission is made to be conspicuous.
