Abstract
An apparatus is disclosed for inclination detection wherein infrared transmitted signal, signal groups S1, S2, S3, . . . including a leader code, a parity bit and bits for data transfer are sequentially transmitted with an interval time t3. At each bit of the signal group S1, "1" and "0" of a binary signal expressing the data are not inverted, at the signal group S2, "1"and "0" expressing the data are inverted, and inversion and non-inversion are repeated every signal group. At bits of each signal group, since a time length expresses "1" and "0", a total time length of each signal group is different from that of other signal group. By repeating sets of inverted and non-inverted signal groups, the time length of each set is averaged, and hence, data processing can be made more efficient.
