Seesaw type operation unit used for zooming operation in video camera and electronic device

An electronic device, comprising:

• an operation unit;
• and
• a driver that performs a predetermine operation in accordance with a signal output from a detector of the operation unit,
• wherein the operation unit includes a swinging member capable of swinging in a predetermined direction with a rotation axis at a center, an urging member that urges the swinging member to a neutral position, the detector that includes a rotating portion which is arranged coaxially with the rotation axis and rotates integrally with the swinging member, and outputs a signal depending on a rotation amount of the rotating portion, a circuit board on which the detector is mounted, an operating member that receives an operation from an outside and causes the swinging member to rotate in the predetermined direction by the operation, a supporting member that rotatably supports the swinging member and the operating member coaxially with each other, and an elastic member that is arranged in a state of being compressed between the circuit board and the supporting member and suppresses a rattling of the circuit board, and
• in a case where the operating member is rotated in the predetermined direction, the operating member pushes an end of the swinging member to rotate the operating member, the swinging member, and the rotating portion integrally with one another.
