Abstract
An electronic apparatus having an input device is disclosed. The input device is capable of reducing the sound generated when an operation-input part returns to its original position after being pressed. The input device includes a base plate having a hook standing towards the operation-input part. The operation-input part has an arm member that can come into contact with the hook. A contact of the arm member with the hook specifies an ascending limit of the operation-input part, and at least one of the arm member and the hook has elasticity in their contacting direction to reduce rebound sound.
