    摘要: To reduce a change in an electric current flowing through a cold cathode discharge lamp caused by a change in power source voltage. There is provided a cold cathode discharge lamp lighting circuit, in which a secondary high voltage of a transformer 13 is changed by controlling an oscillating period of a ROYER oscillating circuit 12 by a duty ratio of a PWM signal, to thereby control an amount of the electric current flowing through a cold cathode discharge lamp 11. In this lighting circuit, a resistor Rx is additionally connected between an inversion input terminal of a comparator X4 for generating the PWM signal and a power source, and a power source voltage divided by resistors Rx and R20 is inputted to the inversion input terminal. Thus, when the power source voltage is changed in an increase direction, an oscillating voltage is increased and the electric current flowing through the cold cathode discharge lamp begins to increase. However, since a voltage inputted to the comparator X4 through the resistor Rx is increased, an H (high voltage) period of the PWM signal is shortened and the oscillating period of the ROYER oscillating circuit is shortened, so that the electric current flowing through the cold cathode discharge lamp is reduced. The change in the electric current caused by the change in the power source voltage is reduced by this operation in a reverse direction.

    摘要: A structure for preventing an image being shaken when a vibration occurs in an optical system so as to stabilize the object. A compensating lens is incorporated in a third lens group of a lens barrel constituting the optical system. The compensating lens is allowed to move within the third lens group and only in a direction perpendicular to the optical axis. A pulse motor mounted on a fixed barrel drives the compensating lens. The rotation of the pulse motor is converted into the rotation of an interlocking lever. The interlocking lever is a straight bar having an uncircular sectional configuration. A driving lever having approximately the same configuration as the sectional configuration of the interlocking lever is slidably inserted thereinto. The driving lever rotates together with the interlocking lever. One end of the driving lever penetrates through the frame of the third lens group, thus contacting the head portion of a pin which presses the compensating lens. When the driving lever rotates, the compensating lens is pressed through the pin. At a position opposed to the pin, a plate urged by a leaf spring supports the compensating lens. A mechanism for driving the compensating lens is provided in x-direction and y-direction with respect to the compensating lens. When the driving lever rotates in the opposite direction, the compensating lens is moved to the initial position by the elastic force of the leaf spring.
