Manual pulse generating device

A manual pulse generating device, comprising:

• a rotatable dial movable along a pressing direction in a first direction, wherein the rotatable dial is biased so as to be located in an initial position located in a second direction opposite the first direction;
• a pulse generating unit configured to generate drive pulses for commanding axial movement of a machine tool in accordance with an amount of rotation of the dial;
• and
• a casing having the dial disposed on a surface of the casing, and configured to accommodate the pulse generating unit in an interior of the casing, the casing has an accommodating recess formed on the surface of the casing configured to accommodate the dial therein when the dial is moved in the first direction;
• and
• wherein, when the dial is pressed in the first direction toward the casing, the dial is accommodated in the accommodating recess and the pulse generating unit enables the axial movement in accordance with the drive pulses, wherein:
• the dial is disposed so as to be movable along a pressing direction of the dial, and is biased so as to be located in an initial position in relation to a pressing direction of the dial;
• the dial and a rotary shaft connected to the pulse generating unit are fitted together and become capable of rotating when the dial is pressed down from the initial position;
• and
• when the dial is pressed down from the initial position, the pulse generating unit generates the drive pulses in accordance with the amount of rotation of the dial, and thereby enables the axial movement in accordance with the drive pulses.
