Abstract

A manual pulse generating device is equipped with a rotatable dial, a pulse generating unit configured to generate drive pulses for commanding axial movement in accordance with an amount of rotation of the dial, an enable switch configured to switch between enablement and disablement of axial movement in accordance with the drive pulses, and a casing having the dial and the enable switch disposed on a surface thereof, and configured to accommodate the pulse generating unit in the interior thereof. The guard configured to cover at least a portion of an outer circumferential surface of the dial is attached to the casing.

Claims

1. A manual pulse generating device, comprising:

a rotatable dial;

a pulse generating unit configured to generate drive pulses for commanding axial movement in accordance with an amount of rotation of the dial;

an enable switch configured to switch between enablement and disablement of axial movement in accordance with the drive pulses; and

a casing having the dial and the enable switch disposed on a surface thereof, and configured to accommodate the pulse generating unit in an interior of the casing;

wherein a guard configured to cover at least a portion of an outer circumferential surface of the dial is attached to the casing.

2. The manual pulse generating device according to claim 1, wherein:

the dial is disposed on a front surface of the casing on one end side in a longitudinal direction of the casing; and

the enable switch is disposed on another end side in the longitudinal direction of the casing.

3. The manual pulse generating device according to claim 2, wherein the enable switch is disposed on the front surface of the casing.

4. The manual pulse generating device according to claim 2, wherein the enable switch is disposed on a side surface of the casing.

5. The manual pulse generating device according to claim 4, wherein the enable switch is disposed on a side surface of the casing that extends along a lateral direction of the casing.

6. The manual pulse generating device according to claim 2, wherein a cable, which is connected to a machine tool in order to output the drive pulses to the machine tool, is disposed on the one end side in the longitudinal direction of the casing on which the dial is disposed.

7. The manual pulse generating device according to claim 6, wherein:

the enable switch is disposed on one end side in a lateral direction of the casing; and

the cable is disposed on another end side in the lateral direction of the casing, so as to be drawn out along the longitudinal direction of the casing.

8. The manual pulse generating device according to claim 6, wherein the cable is disposed so as to be drawn out from a rear surface side of the casing and obliquely with respect to the longitudinal direction of the casing, and so as to be separated away from the dial.

9. The manual pulse generating device according to claim 1, wherein the guard is mounted detachably to the casing.

10. The manual pulse generating device according to claim 1, wherein a discharge port, which is configured to allow liquid that has accumulated in the guard to be discharged, is formed in the guard.

11. The manual pulse generating device according to claim 1, wherein the guard is constituted from an elastic material.
