Filed: 1990-11-21
Abstract: PURPOSE:To increase the winding resistance of a stepping motor and reduce a power consumption by driving the stepping motor at a step rate which enables a larger torque to be taken out in an unloading operation which requires the large torque. CONSTITUTION:In an unloading operation, a driving circuit 14 excites a stepping motor 7 at a large step rate, rotates a cam 9, pushes up an arm 10 against the force of a spring 12 and raises a second carriage 5 against pressing means 6 as a result.

At this stage, the transistor 7 becomes a conducting state when a gate potential is at L and a part between other two terminals has a certain resistance value; when the gate potential is at H, the part between the other two terminals has an infinitely large resistance value and becomes a nonconducting state. The transistor 7 to which the L has been input becomes a conducting state; when the signal from the terminal 4 is neither H nor L and in a high resistance state, it passes through the transistor 7 and an input buffer 6 from a power supply 8; the H is transferred to an internal signal output terminal 3.
