ABSTRACT:
An animation frame including a front frame body, a back plate installed therein with a grating plate and frame brackets, a moveable plane plate stuck with pictures, a battery, an IC circuit board and coils etc. The grating plate is placed on the pictures on the plane plate and fixed on a main body of the back plate; the plane plate has two notches respectively on its upper and lower edges, a vertical plane perpendicular to the plane plate has thereon a magnet between the two coils of the main body. The main body has thereon a movable device connecting with a movable screw and being fixed or adjusted to slide left or right to adjust the angular position of the plane plate. The main body has therein two movable screws connectable with the main body to adjust the plane plate in up and down moving. The magnet is provided at suitable distances from its two lateral sides each with a coil controlled by an IC circuit to generate an S or N polarity, according to the principle of “like charges repel while unlike charges attract”, the pictures can move to and fro between two fixed positions, so that effects that the two pictures are changed within a short duration when they are alternately changed with each other and the two pictures are entirely presented in long durations can be achieved.
