Abstract
A motor-powered apparatus according to one aspect of the present disclosure comprises a motor, a drive switch, a reverse switch, and a control unit. The control unit is configured to drive the motor in a reverse direction when a drive command is inputted via the drive switch after a reverse command is inputted via the reverse switch and to drive the motor in a forward direction when the drive command is inputted again via the drive switch.
Claims14
A motor-powered apparatus comprising:
- a motor;
- a drive switch that is configured to input a drive command for the motor;
- a reverse switch that is configured to input a reverse command that switches a rotational direction of the motor from a forward direction to a reverse direction, the reverse direction being a rotational direction opposite to the forward direction;
- and
- a control unit that is configured to
- drive the motor in the reverse direction without driving the motor in the forward direction when the drive command is inputted via the drive switch after the reverse command is inputted via the reverse switch,
- set the rotational direction of the motor in the forward direction when the input of the drive command is stopped, and
- drive the motor in the forward direction without driving the motor in the reverse direction when the drive command is inputted again via the drive switch without the input of the reverse command.

A method of controlling a motor-powered apparatus that comprises a motor;
- a drive switch that is configured to input a drive command for the motor;
- and a reverse switch that is configured to input a reverse command to switch a rotational direction of the motor from a forward direction to a reverse direction, the reverse direction being a rotational direction opposite to the forward direction,
- the method comprising:
- detecting that the reverse command is inputted via the reverse switch;
- detecting that the drive command is inputted via the drive switch after detecting that the reverse command is inputted via the reverse switch;
- driving the motor in the reverse direction without driving the motor in the forward direction when detecting that the drive command is inputted via the drive switch after the reverse command is inputted;
- setting the rotational direction of the motor in the forward direction when the input of the drive command is stopped;
- detecting that the drive command is inputted again via the drive switch after the input of the drive command is stopped;
- and
- driving the motor in the forward direction when detecting that the drive command is inputted again via the drive switch without the input of the reverse command.
