Electronic apparatus

An electronic apparatus comprising:

• an operation member that is rotationally operable;
• a rotation detection substrate provided with a rotation detector configured to detect rotation of the operation member;
• a capacitance detector provided inside the operation member and configured to output a detection signal in accordance with capacitance;
• a signal transfer unit configured to transfer the detection signal to the rotation detection substrate;
• and
• a touch operation detector to which the detection signal is input through the rotation detection substrate, the touch operation detector being configured to detect a tap operation and a slide operation as a touch operation onto an outer surface of the operation member based on change in the detection signal due to the touch operation;
• wherein part of the operation member is an operable portion capable of the touch operation onto the outer surface, and the capacitance detector provided inside the operable portion includes a plurality of electrodes adjacent to each other, and
• wherein the touch operation detector
• compares capacitance of a first adjacent electrode and capacitance of a second adjacent electrode, the first adjacent electrode being provided adjacent on a first side of an electrode having maximum capacitance among the plurality of electrodes, the second adjacent electrode being adjacently provided on a second side opposite the first side, and
• detects the tap operation onto a range on the first side of the operable portion in a case where the capacitance of the first adjacent electrode is smaller than the capacitance of the second adjacent electrode, and detects the tap operation onto a range on the second side of the operable portion in a case where the capacitance of the second adjacent electrode is smaller than the capacitance of the first adjacent electrode.
