Abstract
A timepiece includes a motor control unit driving a motor for driving an indicating hand, based on an instruction signal, and a control unit receiving an instruction confirmation signal corresponding to a drive state of the motor in response to the instruction signal from the motor control unit, and determining whether or not the motor is driven in accordance with the instruction signal, based on the instruction confirmation signal.
Claims9
A timepiece comprising:
- a motor control unit driving a motor for driving an indicating hand, based on an instruction signal;
- and
- a control unit receiving an instruction confirmation signal corresponding to a drive state of the motor in response to the instruction signal from the motor control unit, and determining whether or not the motor is driven in accordance with the instruction signal, based on the instruction confirmation signal,
- wherein the motor control unit includes a motor drive state determination circuit determining the drive state of the motor, and an instruction confirmation circuit generating an instruction confirmation signal,
- wherein in a case where the motor is driven and the instruction signal is input to the motor, the instruction confirmation circuit generates a first instruction confirmation signal,
- wherein in a case where the motor is not driven and the instruction signal is input to the motor, or in a case where the motor is driven or is not driven and the instruction signal is not input to the motor, the instruction confirmation circuit generates a second instruction confirmation signal, and
- wherein in a case where the control unit receives the first instruction confirmation signal, the control unit determines that the motor is not driven in accordance with the instruction signal.
A motor control device comprising:
- a motor drive state determination circuit determining a drive state of a motor;
- and
- an instruction confirmation circuit generating an instruction confirmation signal indicating a state where the motor is driven based on an instruction signal,
- wherein in a case where the motor is driven and the instruction signal is input to the motor, the instruction confirmation circuit generates a first reception confirmation signal, and
- wherein in a case where the motor is not driven and the instruction signal is input to the motor, or in a case where the motor is driven or is not driven and the instruction signal is not input to the motor, the instruction confirmation circuit generates a second reception confirmation signal.
A motor control method of a motor control device including a motor drive state determination circuit determining a drive state of a motor, and an instruction confirmation circuit generating an instruction confirmation signal indicating a state where the motor is driven based on an instruction signal, the method comprising:
- causing the instruction confirmation circuit to generate a first reception confirmation signal, in a case where the motor is driven and the instruction signal is input to the motor;
- and
- causing the instruction confirmation circuit to generate a second reception confirmation signal, in a case where the motor is not driven and the instruction signal is input to the motor, or in a case where the motor is driven or is not driven and the instruction signal is not input to the motor.
