Abstract
An apparatus includes a rotation detection unit, a direction determination unit, a position detection unit, and a control unit configured to perform control such that the position detection unit is energized in a case where the rotation direction determined by the direction determination unit is a first direction where the first member and the second member approach each other, and that the position detection unit is not energized in a case where the rotation direction determined by the direction determination unit is a second direction where the first member and the second member separate from each other.
Claims19
An apparatus comprising:
- a rotation detection unit configured to detect rotation of a rotating body;
- a determination unit configured to determine a rotation direction of the rotating body based on an output of the rotation detection unit;
- a position detection unit configured to detect a predetermined position of the rotating body based on positions of a first member provided on the rotating body and a second member provided on a fixed section that moves relative to the rotating body;
- and
- a control unit configured to perform control such that the position detection unit is energized in a case where the determined rotation direction is a first direction where the first member and the second member approach each other, and that the position detection unit is not energized in a case where the determined rotation direction is a second direction where the first member and the second member separate from each other.
A method for controlling energization to a position detection unit configured to detect a predetermined position of a rotating body, the method comprising:
- detecting rotation of a rotating body;
- determining a rotation direction of the rotating body on a basis of a result of detected rotation;
- detecting a predetermined position of the rotating body based on positions of a first member provided on the rotating body and a second member provided on a fixed section that moves relative to the rotating body;
- and
- performing control such that a position detection unit is energized in a case where the rotation direction determined in the direction determination is a first direction where the first member and the second member approach each other, and that the position detection unit is not energized in a case where the rotation direction determined in the direction determination is a second direction where the first member and the second member separate from each other.
A non-transitory computer-readable storage medium storing a program for causing a computer to execute a method for controlling energization of a position detection unit configured to detect a predetermined position of a rotating body, the method comprising:
- detecting rotation of a rotating body;
- determining a rotation direction of the rotating body on a basis of a result of detected rotation;
- detecting a predetermined position of the rotating body on a basis of positions of a first member provided on the rotating body and a second member provided on a fixed section that moves relative to the rotating body;
- and
- performing control in such a manner that a position detection unit is energized in a case where the rotation direction determined in the direction determination is a first direction where the first member and the second member approach each other, and that the position detection unit is not energized in a case where the rotation direction determined in the direction determination is a second direction where the first member and the second member separate from each other.
