Abstract
A hand position control device includes a mode switching unit that is capable of switching between a normal hand movement mode and a manual hand position setting mode and a control unit that sets a pulse width of a driving pulse to be output to a coil of a motor that rotates a hand and sets a manual pulse width of the driving pulse in the manual hand position setting mode to be larger than a normal pulse width of the driving pulse in the normal hand movement mode.
Claims8
A hand position control device comprising:
- a mode switching unit that is capable of switching between a normal hand movement mode and a manual hand position setting mode;
- and
- a control unit that sets a pulse width of a driving pulse to be output to a coil of a motor that rotates a hand and sets a manual pulse width of the driving pulse in the manual hand position setting mode to be larger than a normal pulse width of the driving pulse in the normal hand movement mode.
A hand position control method in a hand position control device including a control unit for setting a pulse width of a driving pulse to be output to a coil of a motor that rotates a hand, the method comprising:
- a step of allowing a mode switching unit to switch between a normal hand movement mode and a manual hand position setting mode;
- and
- a step of allowing the control unit to set a manual pulse width of the driving pulse in the manual hand position setting mode to be larger than a normal pulse width of the driving pulse in the normal hand movement mode at the time of the manual hand position setting mode.
