9. The remote gas meter reading apparatus according to claim 8,
the camera (40) transmits the photographed image to a transmitter through an RF transmission means, and the transmitter not only stores the photographed image in a memory section but also reads a digital data from the photographed image and transmits the read digital data to a computer of a gas supplier at a remote site through a communication network.
10. The remote gas meter reading apparatus according to claim 8,
a clamp bracket (130) is jointed to the front surface of a transparent cover (112) of an instrument panel covering the meter (10), a long square hole (132) is formed in the center of an attachment surface (131) of the clamp bracket (130) so as to expose the number of the instrument panel (11), a shell (120) is inserted into 4 elastic clamps (133, 134, 135, 136) to be fixed, and the 4 elastic clamps (133, 134, 135, 136) are formed around the attachment surface (131).
11. The remote gas meter reading apparatus of claim 10,
the width (W1) of the upper elastic clamp 133 among the elastic clamps (133, 134, 135, 136) is formed to be the same as the width (W2) of the case (120).
12. The remote gas meter reading apparatus of claim 10,
a double-sided tape (140) is attached to an attachment surface (131) of a clamping bracket (130) and a transparent back plate (121) of a case (120) so as to expose a square hole (132) formed in the center of the attachment surface (131) of the clamping bracket (130).
