a rotary plate which is rotatable around the rotational axis; a connecting member for connecting the rotary shaft and the rotary plate, which retracts in an axial direction of the rotary shaft and does not retract in a rotary direction of the rotary plate; and an output terminal for outputting a signal in accordance with rotation of the rotary plate. ## Claims ### Claim 1 A rotary operation type electronic device comprising: a rotary shaft; a rotary plate which is rotatable around a rotational axis; connection means for connecting the rotary shaft and the rotary plate which, as a result of movement of the rotary shaft in an axial direction, retracts in an axial direction of the rotary shaft and does not retract in a rotary direction of the rotary plate; and output means, operatively coupled to the rotary plate, for outputting a signal in accordance with rotation of the rotary plate as a result of rotation of the rotary shaft, wherein the rotary plate has a donut-like shade including an inner circumference add an outer circumference, and the connection means is connected along the inner circumference of the rotary plate having the donut-like shade. ### Claim 2 (depends on 1) A rotary operation type electronic device according to claim 1, further comprising bushing means having an inner hole into which the rotary shaft is inserted, which allows the rotary shaft to rotate and to move in the axial direction. ### Claim 3 (depends on 1) A rotary operation type electronic device according to claim 1, wherein the connection means is integrally formed with the rotary plate. ### Claim 4 (depends on 1) A rotary operation type electronic device according to claim 1, wherein the connection means and the rotary plate are made of resin. ### Claim 5 (depends on 1) A rotary operation type electronic device according to claim 1, further comprising a push switch which is switched between ON and OFF in response to movement of the rotary shaft in the axial direction. ### Claim 6 (depends on 1) A rotary operation type electronic device according to claim 1, further comprising a push switch which is positioned on the rotary shaft and is switched between ON and OFF in response to movement of the rotary shaft in a direction in which the push switch is positioned. ### Claim 7 (depends on 1) A rotary operation type electronic device according to claim 1, wherein the connection means has a plurality of rings each being connected to adjacent rings, and the connection means has a gimbal structure. ### Claim 8 A rotary operation type electronic device comprising: a rotary shaft; a rotary plate which is rotatable around a rotational axis; connection means for connecting the rotary shaft and the rotary plate which, as a result of movement of the rotary shaft in an axial direction retracts in an axial direction of the rotary shaft and does not retract in a rotary direction of the rotary plate; and output means, operatively coupled to the rotary plate, for outputting a signal in accordance with rotation of the rotary plate as a result of rotation of the rotary shaft, wherein the connection means has a plurality of rings and a plurality of connecting portions for connecting adjacent rings, and the plurality of rings are placed on concentric circles having respectively different radiuses. ### Claim 9 A rotary operation type electronic device comprising: a rotary shaft; a rotary plate which is rotatable around a rotational axis; connection means for connecting the rotary shaft and the rotary plate which, as a result of movement of the rotary shaft in an axial direction, retracts in an axial direction of the rotary shaft and does not retract in a rotary direction of the rotary plate; and output means, operatively coupled to the rotary plate, for outputting a signal in accordance with rotation of the rotary plate as a result of rotation of the rotary shaft, wherein the connection means has a plurality of members which are convexly bendable in the axial direction, each of the plurality of bendable members have an end connected to the rotary plate and the other end connected to the rotary shaft. ### Claim 10 (depends on 9) A rotary operation type electronic device according to claim 9, wherein each of the bendable members has a rib in a tangential direction of the rotary shaft. ### Claim 11 A rotary operation type electronic device comprising: a rotary shaft; a rotary plate which is rotatable around a rotational axis; connecting means embracing the rotary shaft and extending between the rotary shaft and the rotary plate permitting relative axial movement between the rotary shaft and the rotary plate while precluding relative rotation; and output means, operatively coupled to the rotary plate, for outputting a signal in accordance with rotation of the rotary plate as a result of rotation of the rotary shaft, wherein the rotary plate has a donut-like shape including an inner circumference and an outer circumference, and the connecting means is connected along the inner circumference of the rotary plate having the donut-like shape. ### Claim 12 (depends on 11) A rotary operation type electronic device according to claim 11, wherein the connecting means is yieldable in an axial direction. ### Claim 13 (depends on 11) A rotary operation type electronic device according to claim 11, wherein the connecting means varies in axial yieldability radially and is most yieldable where it embraces the shaft.
