ABSTRACT:
A start and stop control apparatus used in controlling the transmission of a series of data frames each showing a character and each composed of start bit, data and stop bit pulses. The apparatus is so designed as to generate a new sampling pulse for every data frame. A number N of binaries "0" which corresponds to the width of the start bit in each data frame are written into a shift register in response to clock pulses. Upon completion of the writing of binaries "0", the shift register forms a loop. A binary "1" is then written into the shift register in place of the N/2th binary "0" when N is even and N.+-.1th/2 binary "0" when N is odd. Every time the binaries "0" and the binary "1" are circulated in the looped shift register in response to clock pulses, there is obtained from the shift register a sampling pulse by which the data pulses are sampled.
