Title: Lens barrel
Inventor: WATANABE TSUNEO
IPC: G02B7/04
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of optical performance by eliminating the play of the moving member of a cam ring of the like with a fixed lens barrel by arranging a backlash preventive member at the groove part of the fixed lens barrel. SOLUTION: Three plate members 18 are arranged between the cam ring 4 and the fixed lens barrel 2. The plate member 18 is constituted of a plate part 18a and a resin part 18b. The plate member 18 is arranged at the groove 2a of the fixed lens barrel 2 so that the plate part 18a is laminated on a flexible printed circuit board (FPC) 21 and the resin part 18b is brought into contact with the inner peripheral surface of the cam ring 4. In this state, the plate member 18 presses the FPC 21 in the direction to the fixed lens barrel 2, namely energizes it. Thus, the plate member 18 prevents the FPC 21 from being raised up from the groove 2a and being brought into contact with the cam ring 4.  Then, the thickness of the resin part 18b is set at the thickness by which the play (backlash) for the fixed lens barrel 2 of the cam ring 4 is eliminated and also the rotary shaft of the cam ring 4 is aligned with an optical axis.

Abstract: PROBLEM TO BE SOLVED: To detect the exchange timing and deterioration phenomenon of an insulator by arranging a capacitor in series and connecting a discharge circuit for discharging the capacitor in parallel when one portion of the capacitor becomes lower than an application voltage. SOLUTION: Capacitors Ci (i=1-n) are connected in series, and an AC application voltage V is applied between capacitors C1 and Cn. An anode A of a triac T is connected between capacitors C2 and C3 via a coil L, a cathode C is connected to a capacitor C1, and a gate G is connected between the capacitors C1 and C2 via a trigger diode D. An allotted voltage between the anode A and the trigger diode D becomes V/n, the gate G is opened when the allotted voltage exceeds the break voltage of the trigger diode D, and the triac T conducts electricity. As a result, the capacitors C1 and C2 are discharged, the anode A and the cathode C become an equal voltage, and the triac T does not conduct electricity. A needle-shaped wave generation circuit enables the state of an insulator to be estimated.
