Input device and electronic apparatus comprising same

An input device comprising:

• an electrode sheet directly sensing a change in capacitance at a position where an object approaches when the object approaches the electrode sheet;
• a plurality of keys disposed on the electrode sheet and configured to be depressed;
• and
• a controller configured to:
• detect (i) a capacitance change amount at a position of one key of the plurality of keys on the electrode sheet and (ii) a capacitance change amount at a position of a specific key of the plurality of keys,
• output, in response to (i) the detected capacitance change amount at the position of the one key being larger than a first given amount and smaller than a second given amount larger than the first given amount and (ii) the detected capacitance change amount at the position of the specific key being equal to or larger than the second given amount, positional information indicating the position of the one key, and
• output, in response to (i) the detected capacitance change amount at the position of the one key being equal to or larger than the second given amount and (ii) the detected capacitance change amount at the position of the specific key being smaller than the second given amount, key information indicating the one key.
