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

(1) Device Configuration FIG. 1 is a sectional view of a data input / output device 20 of the present invention to which a radio paging receiver 10 of the present invention is attached. In FIG.
1 is an external signal input / output connector plug, 2 is a back cover fixing screw, 3 is an external signal input / output connector jack, 10 is a radio call receiving device, 11 is a radio call receiving device substrate, 12 is an elliptical lens, and 14 is a radio calling. Receiving device housing, 16 radio call receiving device light receiving and emitting element, 19 control circuit, 20 data input / output device, 21 radio call receiving printed circuit board, 22 circular lens, 25 connector, 26 data input / output The device light receiving and emitting element, 27 is a guideline, 28 is a data input / output device housing, and 29 is a control circuit.

FIG. 2A is a bottom view of the radio paging receiver of the present invention, and FIG. 2B is a top view of the data input / output device of the present invention. 3 is a perspective view of the data input / output device of the present invention. 2 and 3, the same parts as those in FIG. 1 are designated by the same reference numerals.

The data input / output device 20 exchanges signals with the radio paging receiver 10 by an optical interface while being placed on the upper surface of the data input / output device 20. Relative positioning of the radio paging receiver 10 and the data input / output device 20 is performed by sliding the radio paging receiver along the guideline 7 attached to the upper surface of the data input / output device 20,
It is done by putting it in Guideline 7 without any gaps. By vertically matching the optical signal input / output units of the radio paging receiver 10 and the data input / output device 20, reading and writing of data stored in the radio paging receiver and reading of messages received by the radio paging receiver are performed. To do.

The light emitting and receiving elements 16 and 26 are mounted on the printed circuit boards 11 and 21, respectively. The housing 14 of the radio paging receiver 10 and the housing 2 of the data input / output device 20 are provided with a hole for passing infrared light between the light emitting and receiving elements 16 and 26.
It is provided in 4. The elliptical lens 12 is fitted into the hole of the housing 14 in order to collect infrared light. Further, the ordinary circular lens 22 is fitted into the hole of the housing 24. Light emitting and receiving element 16
And 26 are each composed of a light emitting element and a light receiving element provided adjacent to each other. An LED can be used as the light emitting element, and a phototransistor can be used as the light receiving element.

Since the light emitting element and the light receiving element are provided very close to each other, the light emitted from the radio paging receiver and the data input / output device can pass through the same lenses 12 and 22. Further, in the present invention, bidirectional simultaneous communication is not performed, and only one of the radio paging receiver and the data input / output device transmits at a certain moment.

Since the radio paging receiver 10 and the data input / output device 20 do not transmit at the same time, the reception (light reception) signal is ignored while the self device transmits (emits light). Therefore, the surface reflection of the lens does not affect the received signal. Therefore, according to the present invention, the radio paging receiver 1
0 and the data input / output device 20 do not require a strict optical system design. Therefore, the lens for collecting the light emitted from the radio paging receiver 10 and the light emitted from the data input / output device 20 are collected. There is no need to provide the lens separately.

The light receiving element and the light emitting element of the radio paging receiver 10 are arranged so as to face the light emitting element and the light receiving element of the data input / output device, respectively. The light-receiving and light-emitting elements 16 of the radio page receiver 10 and the data input / output device 20,
A hole for allowing infrared light to pass through is provided on 26. To collect infrared light, an elliptical lens 12 is fitted into the hole provided in the radio paging receiver 10. The elliptical lens is used to make the outer shape of the lens as small as possible based on design requirements. The major axis of the ellipse is aligned with the arrangement direction of the light receiving element and the light emitting element. A circular lens 22 is fitted into the hole provided in the data input / output device 20.

In the present invention, the diameter of the spot of the infrared rays that have passed through the respective lenses on the opposing light receiving element is about 6 mm. Since the radio paging receiver and the data input / output device do not simultaneously transmit, it is not necessary to consider the influence of the reflected light of the light emitted by itself, and the spot diameter can be increased in this way. Therefore, according to the present invention, the radio paging receiver 10 and the data input / output device 2 are
With respect to 0, strict positioning accuracy is not required. If the spot system is too large, the brightness of the condensed light will decrease. Based on the experiments of the present invention, the spot system is 3 mm-1.
0 mm is optimal.

However, the condensing means of the radio paging receiver and the data input / output device of the present invention is not limited to the lens, and may be a transparent flat plate through which light can pass.

(2) Device operation From the radio paging receiver 10 to the data input / output device,
A procedure for transmitting data such as a reception message will be described.
The radio paging receiver 10 first converts the data to be transmitted into an LED drive signal and supplies it to the light receiving and emitting element 16 in the control circuit 19 by the start-stop synchronization method with a signal speed of 2400 bps, for example, by setting the transmission order to LSB. The light receiving and emitting element 16 emits light based on the received LED drive signal. The data input / output device 20 receives an optical signal by the light receiving / emitting element 26, and the control circuit 29 uses, for example, JIS X02.
The data signal is converted into a data code conforming to 08 and the signal is output from the electric signal input / output connector 10.

As the communication method, for example, a method based on the basic procedure (JIS: contention method) can be used. According to this method, the transmitting side sends a request signal after transmitting one block, and the receiving side starts transmission after receiving the request signal.

When writing or reading information such as the ID of the radio paging receiver 10, it is necessary to manage security. Therefore, the cryptographic information used when reading or writing information that requires security management is registered in the radio paging receiver 10 in advance. When reading or writing information that requires security management, the wireless call receiving device 1 is connected to the data input / output device 20.
Send encrypted data to 0. The wireless call receiving device 10 determines whether the received encrypted data is the same as the encrypted data registered in advance in the wireless call receiving device 10, and only when the encrypted data is equal, the reading or writing of information requiring security management is permitted. .

[0027]

As described above, according to the present invention,
Data such as ID information or pattern information stored in the radio pager can be easily read and written without removing the back cover of the radio pager. Further, according to the present invention, the message received by the radio paging receiver can be easily retrieved.

Further, according to the present invention, since it is possible to form a case that is electrically insulated from the outside, it is possible to provide the radio paging receiver 10 and the data input / output device 20 that are resistant to electrostatic noise.
