27に収納される。The response device 8 is provided with an antenna 15 that receives energy waves wirelessly transmitted from the antenna 7.
The energy wave received at 5 is applied to a PSK modulator 16 and a rectifier circuit 17. The energy wave applied to the rectifier circuit 17 is rectified and converted into a DC voltage, which is outputted as DC operating power of the response device 8 via a low-pass filter 18 .

ることができる。In such a configuration, the homodyne detector 1 of the interrogation device 1
3 obtains the first demodulated data from the PSK-modulated transmission signal wave using the first frequency f1 as a carrier wave, and the second receiving means of the high frequency receiving device 28 obtains the first demodulated data from the PSK-modulated transmission signal wave using the first frequency f1 as a carrier wave. Second demodulated data is obtained from the harmonic components amplitude-modulated using a frequency 2f, which is twice the frequency of f, as a carrier wave. Although the first and second demodulated data are based on the same data from the response device 8, since the carrier frequency, modulation method, and propagation path are different, the effects of fading, external noise, etc. are different. Therefore, if the first and second demodulated data match in Comparison 35 as a means of comparison, it is because the first demodulated data has not been affected by fading or external noise, and the data has been received correctly. I can confirm that 6M has been demodulated. and,
By housing the interrogation device 1 and the high frequency receiving device 28 in separate housings 14.34, the positions of the first and second receiving means can be appropriately separated and the propagation paths can be easily changed. I can do it.

The number of claims increased by the amendment: 17, the scope of claims and detailed description of the invention in the specification subject to the amendment. 8. Contents of amendment (1) The claims of the specification will be amended as shown in the attached sheet. (2) Delete "stored in the first casing" in the second line of page 4 of the specification. (3) Delete ``stored in a second casing separate from the first casing'' in lines 4 to 5 of page 4. (4) Insert note F between page 4, line 16 and line 17. Furthermore, the first receiving means may be housed in a first housing, and the second receiving means may be housed in a second housing separate from the first housing. , J (5) From the 19th line of the 4th page to the 1st line of the 5th page, ``because it is received, and...different'' is corrected to ``because it is received''. (6) Correct "passed through a fiery propagation path at wave number" in line 2 of page 5 to "1 at wave number." (7) Between line 12 and line 13 of page 5L'1, write the following: ``Additionally, the first and second receiving means may be housed in separate housings.
If the first and second receiving means can receive the red radio (PI wave) in different propagation routes, the first and second receiving means will be able to receive the PI wave in a thousand waves, so it will be more effective. = The effects of layer fading and external noise are different, and it is possible to determine with higher reliability whether data is being received reliably.'' (8) Delete ``and propagation path'' in line 19 of page 11 of the same page. (9) Insert the following between line 7 and line 8 of page 12. Radio signal waves are received (24 Sane,
It is possible to more reliably determine whether accurate data is being received. ” Attachment (Patent Q-T-A No. 4592) “2. Claims (1) A first receiving means for receiving a transmission signal wave whose carrier wave is modulated according to data; a second receiving means that receives harmonic components of the carrier wave on which data is superimposed; and first demodulated data received and demodulated by the first receiving means; and 1) η received by the second receiving means. A data receiving device characterized by comprising: comparing means that compares demodulated second demodulated data and outputs a coincidence signal when they match. (2) The transmission signal wave is phase modulated, and the transmission signal wave is phase modulated, and 2. The data receiving device according to claim 1, wherein the first receiving means homodyne-detects the transmitted signal wave, and the second receiving means linearly detects harmonic components of the carrier wave. Claim 1, wherein the first receiving means is housed in a first casing, and the second receiving means is housed in a second casing separate from the first casing. or the data receiving device described in 2.
