PURPOSE:To enable adjustment to be rapidly performed by so arranging the device that the time adjustment direction is reversed when the signals form two time adjustment operation terminals are simultaneously emitted. CONSTITUTION:When the signal from a fast feed operation terminal 5 or slow feed operation terminal 6 is independently applied, a 50/60-Hz or 2-Hz input is applied to a minute counter 2 by AND gates L1, L5 or L2, L6 and OR gate L7, letting the counter revolve forward. When the fast feed signal and slow feed signal are simultaneously applied, the outputs of the AND gates L5, L6 are stopped by a NAND gate L4. |
