Abstract
A non-contact sensor includes a substrate having a groove, two pattern coils arranged on opposite sides of the groove, a detected object connected to the shift lever and moved in cooperation with the shift lever along the groove, and a signal processing circuit that calculates a movement amount of the shift lever based on an output value provided from the pattern coils.
Claims10
A non-contact sensor that detects a movement amount of a detection subject, the non-contact sensor comprising:
- a substrate including a groove;
- a plurality of pattern coils including two opposing pattern coils arranged on opposite sides of the groove;
- a detected object connected to the detection subject and moved in cooperation with the detection subject along the groove, wherein movement of the detected object changes a degree of magnetic coupling between the two pattern coils;
- and
- a signal processing circuit that calculates a movement amount of the detected object based on an output value provided from the pattern coils.

A shift lever device comprising:
- a substrate including a groove;
- a movable detected object connected to a shift lever and moved in cooperation with the shift lever along the groove;
- two opposing pattern coils arranged on opposite sides of the groove, wherein a degree of magnetic coupling between the two pattern coils changes in accordance with where the detected object is positioned;
- and
- a signal processing circuit calculates an operational position of the shift lever based on an output value from one of the two pattern coils.

A shift lever device comprising:
- a shift lever;
- and
- a non-contact sensor that detects where the shift lever is positioned,
- wherein the non-contact sensor includes
- a substrate including a front surface, a rear surface, a groove, and a plurality of coil elements arranged on opposite sides of the groove to allow for magnetic coupling therebetween, and
- a movable block connected directly or indirectly to the shift lever and moved along the groove,
- wherein each of the coil elements includes
