Abstract

PURPOSE:To reduce measuring cost by providing a clear terminal control section to clear the reception state of a receiver without the operation of the mechanism, thereby forming the measuring system inexpensively for the automation of the confirmation of the reception operation of the receiver. CONSTITUTION:A clear SW 6 is provided to bring the receiver into the reception state again, and when the SW 6 is closed, a decoder 5 detects it to bring the state of the receiver into the reception state again. A clear terminal control section 11 receives a luminous quantity signal (a) and forms the same state of the clear SW 6 closed when a changing pattern of the signal is coincident with a predetermined pattern and inputs the result to the clear terminal of the decoder 5. The decoder 5 detects it, clears reception information and to bring the receiver into the receptible state again. Thus, the clear SW depression mechanism to bring the receiver into the reception state again is not required in the automatic operation confirmation and the measuring cost is reduced.

FIG. 3 is a block diagram showing an example of a conventional wireless selective calling receiver with a display function.

A receiving antenna l receives a carrier wave modulated with a personalized selective calling number and display information. The radio section 2 inputs the carrier wave, demodulates it, and outputs it as a demodulated signal. The waveform shaping circuit 3 inputs the demodulated signal, converts it into a digital signal, and outputs it as a decoded signal. The storage unit 4 stores a self-calling number in advance. The decoder 5 controls the storage unit 4 to retrieve the self-calling number, compares it with the individually selected calling number in the decoded signal input from the waveform shaping circuit 3, and if they match, the flicker signal and the display information following the self-calling number output separately. The display device 7 inputs the display information and displays it using letters, numbers, symbols, etc. The flicker indicator lamp l2 performs a flicker operation based on a flicker signal. The light amount detector 9 converts the external light amount into a light amount signal a and outputs it. The illumination control unit IO receives the light amount signal a, and if a predetermined amount of light is obtained, controls the display illumination unit 8 to turn off the illumination.

If the predetermined amount of light cannot be obtained, the display illumination section 8 is controlled to turn on the illumination. That is, if the outside is sufficiently bright, the display illumination section 8 is turned off, and if the outside is dark, the display illumination section 8 is turned on before the display 7 can be seen. Clear SW6 is provided to set the reception mode again, and O
The decoder 5 detects this and enters the receiving state again.

By the way, in order to evaluate the performance of a wireless selective call receiver with a display function, it is necessary to check the reception operation at the time of manufacture or during maintenance. With a wireless selective calling receiver with a display function, once an individual selective calling number and display information that match the self-calling number are received, they are retained internally, so if you want to confirm reception again, press the clear switch to clear the received information. need to be erased.
