BACKGROUND OF THE INVENTION
 1. Field of the Invention
 The present invention relates to a monitor toy assembly.
 2. Description of the Related Art
 A conventional toy sold in the market is commonly used for a child to play
 with so as to achieving an amusing and playing effect. However, the
 conventional toy can only provide a monotonous and tedious amusement to
 the children without a functional variation, and cannot be adapted to have
 any other utility effect so that such a conventional toy cannot fit the
 practical requirement in the modern world, thereby greatly limiting the
 versatility of the conventional toy.

 In operation, referring to FIGS. 7-10 with reference to FIGS. 1-6, the
 support frame 1 of the monitor toy assembly is initially secured to a
 ceiling 7 of an office as shown in FIG. 7. The rotary platform 2 can be
 pivoted relative to the support frame 1 as shown in FIG. 8, thereby
 adjusting the inclined angle of the casing 3 so that the camera lens 67
 can align with a optimal position of the inlet of the office.
 When the sensor 65 of the front cover 6 detects that a person approaches
 the inlet of the office, the detected signal is then delivered to the
 integrated circuit board 34 which then drives the actuating device 4 to
 operate the motor 42 (see FIGS. 5 and 6) which rotates its shaft which
 rotates the first belt wheel 421 which rotates the second belt wheel 423
 through the belt 422 to rotate the pinion 43 which in turn rotates the
 first reduction gear 44, the second reduction gear 45, the third reduction
 gear 46, and the fourth reduction gear 47 which rotates the rectangular
 drive shaft 471 which rotates the eccentric wheel 48 which moves the
 eccentric rod 481 in the elongated slot 222 of the linking lever 22,
 thereby in turn horizontally rotating the casing 3 relative to the rotary
 platform 2 between the positions as shown in FIGS. 9 and 10 so that the
 casing 3 can be reciprocally rotated rightward and leftward. At the same
 time, the light emitting component 64 of the front cover 6 can be adapted
 to emit light during horizontal rotation of the casing 3 so as to create
 an active effect like a real monitor so that the monitor shaped toy
 assembly of the present invention can be simulated as a real monitor,
 thereby achieving a warning effect.
 It should be clear to those skilled in the art that further embodiments may
 be made without departing from the scope of the present invention.
