Abstract: PURPOSE:To always sample accurate data with a clock having an optimum phase by holding a sampling clock matched to broadcast standards and obtaining the delay time of sampling data based on a teletext signal itself. CONSTITUTION:The teletext signal is sliced by a slicing circuit 3 and is converted to binary data. Sampling clocks where one CRI(clock run in) section is separated into, for example, 16 phases are generated by a sampling clock generating circuit.

Filed: 1989-04-19
Abstract: PURPOSE:To reduce the load of CPU and to stop a carrier motor reliably by providing a flipflop for inverting the output level in response to the carrier detecting operation of a sensor during printing operation and a gate circuit for disabling phase signal supply to the carrier motor in response to the inversion. CONSTITUTION:A phase signal is fed to a carrier motor driver 29 in order to rotary drive a carrier motor 5 and to move a carrier 2 toward a home position. When the carrier 2 passes through the home position and a home position sensor 7 is turned ON, output to be fed to PR1 input terminal of a flipflop 28 is switched to high level. Consequently, output level at a Q output terminal can be inverted from high to flow through falling of a signal provided to CK input terminal. The carrier motor 5 is rotated reversely, under this state, thus moving the carrier 2 toward the home position. When the carrier 2 is brought to the home position, the carrier motor 5 is stopped.
