【Example】

 With reference to the drawings, a method of a communication system using infrared light for inputting and outputting an external signal according to the present invention will be described.

FIG. 1 is a sectional view of an essential part of an embodiment of the present invention, FIG. 3 is a front view of a radio paging receiver of the present invention, and FIG. 4 is a side view of an additional device of the present invention.

In FIGS. 1, 3 and 4, 4 is a receiver housing, 5 is a light receiving element, 6 is a light emitting element, 7 is a guide groove, 8 is an additional device, 9 is an optical signal-electrical signal conversion circuit, 10 is an electric signal input / output connector, 11 is a detachable clip, 12 is a claw, 13 is a lens, and 14 is a print plate.

In the present invention, an additional device 8 for external signal input / output is inserted and fitted to the outside of the receiver housing 4 so as to retrieve not only receiver information but also a received message at the time of reception or a wireless call. It retrieves messages in the memory of the receiver and controls the receiver externally.

In the example shown here, an LED is provided as a light emitting element 6 for outputting a signal, and a phototransistor is provided as a light receiving element 5 for inputting a signal, in a printed circuit board 14 adjacent to the receiver. Install. A hole for passing infrared light is provided between the light emitting element 6 and the light receiving element 5 in the housing 4, and a lens 13 for improving the directivity of infrared light is fitted into the hole.

The additional device 8 is a device for exchanging signals with the radio paging receiver through an optical interface, and has a structure to be mounted on the surface of the radio paging receiver.

The light emitting element 6 and the light receiving element 5 are arranged so as to face the light receiving element 5 and the light emitting element 6 of the radio paging receiver, respectively, and a hole through which infrared light passes is provided on the surface thereof. A lens 13 for improving the directivity of infrared light is fitted in the hole.

The light emitting element 6 and the light receiving element 5 which emit infrared light are attached and fixed to the printed board 14. To fix the position of the radio paging receiver and the additional device 8, slide the pawl 12 of the additional device 8 along the guide groove 7 attached to the surface of the radio paging receiver and come to the end of the groove 7. Sometimes fixed with a clip 11 attached to the bottom.

In order to obtain the message received from the external output terminal of the radio paging receiver, the received message is modulated in the electric signal-optical signal conversion circuit, for example, by the “pulse width modulation method” at a signal rate of 2400 bps, Light is emitted from the light emitting element 6 as an optical signal according to the start-stop synchronization method and the transmission order LSB. This optical signal is received by the light receiving element 5 attached to the additional device 8 inserted in the receiver housing 4, and an electric signal is output, and the data code "JIS X 0208" is further output by the optical signal-electric signal conversion circuit. Is converted into a code compliant with the above and is output from the electric signal input / output connector 10.

The exchange of protocol control is performed between the light receiving element 5 attached to the radio paging receiver and the light emitting element 6 attached to the additional device 8 by a method compliant with the XMODEM protocol, for example.

This is a method in which a signal from the transmitting side is being received, the receiving side is on standby, the request signal is sent from the receiving side after receiving one block, and the transmitting side starts transmission after receiving the request signal. is there.

Since security management is required for writing and reading receiver information such as ID, by sending encrypted data to the wireless call receiver at the start of reading or writing, the wireless call receiver can receive the encrypted data. Check on the side.

[0019]

[Effect of device]

 As described in detail above, since the present invention is configured as described above, the message received from the radio paging receiver is extracted to the outside, the receiver is controlled from the outside, and the receiver information is received. There is an effect that writing and the like can be performed by one interface.

Further, since the structure is as described above, it is expected that the connection is highly reliable and no electrostatic countermeasure is required.
