Description of the Invention: [Technical Field] The present invention relates to a projector, and more particularly to a lens zoom control device for a projector. ^ [Prior Art] Refer to Figure 1 'The mirror 帛U used by the conventional projector # adjusts the size of the image projected by the lens U onto the screen by moving the image zooming joystick 12 set on the lens 11, and generally for the appearance For industrial design considerations, the zoom ring 13 is additionally set in the lens U_L, so that the image zooming rocker 12 is inserted into a fixing hole 130 of the zoom ring u. Then the zoom ring 13 is rotated to drive the image zooming joystick. 12 Move to control image size. However, since the image zooming rocker 12 has to be inserted into the fixing hole 130 of the zoom ring 13, the zoom ring 13 must be placed on the periphery of the lens u, and the image of the rocker 12 and the mirror u are zoomed in, so that Limiting the position of the zoom ring 13 is thus limited in design. In addition, there are other operation buttons on the projector that are set in different areas, and the zooming clothes 13 cannot be integrated with other operation buttons due to the above limitation. When the user adjusts the projector, the user's hand must move to different positions. The area of the projector, the operating interface of the conventional projector is less human. SUMMARY OF THE INVENTION One object of the present invention is to provide a projector and a lens zoom control device which are not limited to the periphery of the lens and which can integrate the operation interface of the projector and are more user-friendly. In order to achieve one or a part or all of the above (4) for other purposes, this 200830026 Λ only example lens zoom control device is suitable for mobile projectors.

When the transmission rod 4 is at the first position i7i of the track 17 and the sliding wide-end 431, and when the transmission rod 4 is in the second position, the image zooming 213 The second end 172 of the track 17 and the two ends 432 of the sliding hole. Referring to FIG. 3 and FIG. 4, the driving structure for driving the driving member 5 to move back and forth in a direction 19 perpendicular to the extending direction of the chute is, for example, It is said that the gear member 52 is disposed on one surface of the driving member 5, and the @lens zoom control vibration 2U further includes a gear 8 meshing with the rack 52, and the driving member 5 is driven by the rotation of the gear 8 'The linear movement is generated, and the position of the rack 52 depends on the moving direction of the driving member 5. As shown in Fig. 2 and Fig. 3, by the transmission 4 is arranged such that the driving member 5 can be disposed at other positions on the projector 21 without being disposed at the periphery of the lens 212. In more detail, the driving member 5 and the operating button 214 can be integrated together, for example, The housing 21 of the projector 21 near the button 214 is provided with a hole 216' for the driving member 5 to be placed in the receiving hole 216 to be exposed on the surface of the housing 215 of the projection 8 200830026 for the (4) phase. 511 and sliding hole design, for example, in the embodiment of FIG. 5; ^^ square ^ can also have other angles between - the angle of the sliding hole 43 / projection direction 16 the extension of the sliding hole 43 square (four) red The direction is not parallel with the trajectory 17, 511, the extending direction is parallel to the two directions of the transmission rod 4, the sliding groove, and the extending direction and the projection direction of the sliding groove 511 are: "The acute angle" in the example, the trajectory 17 , perpendicular to the projection direction 16, the solid direction of the graph 6 and the trajectory 17, the extending direction of the non-parallel π movable hole 43 is parallel, and the angle between the sliding groove 51 and the transmission rod 4 is _ sharp: The extending direction is opposite to the extending direction of the transmission rod 4 and the angle 4 is the same as the extension 6 of the sliding slot 511. In the embodiment of FIG. 7; the direction of the extension of the sliding hole 43 and the direction of the trajectory 17^=16 and the extending direction of the transmission rod, the moving hole 43, and the transmission rod-direction two::::11 Direction and projection direction 16 _ , brother angle ' and the groove 511 17 , perpendicular to the projection direction 16 , 4 $ m in the shell example, the execution parallel, sliding ... two two chute 5U, the extension: extension of i The directions are parallel, - acute angle, and the angle between the two slots 511 and the direction of extension of the sliding groove 511 is « 9 ? 〇 ^ and the direction of the track 17, °, '仃, parallel to the extending direction of the moving rod 4 of the sliding hole 43 = Γ The angle between the extending direction of the 43 and the extending direction of the extending direction is an acute angle with the angle of the transmission rod 4, and the extending direction of the slot is 200830026 parallel to the projection direction 16. Referring to FIG. 2 and FIG. 10, the lens zoom control device 22 of the second preferred embodiment of the present invention is different from the first preferred embodiment in that the operation mode of the transmission rod 6 is changed from rotating to moving and the branch can be omitted. Pieces. The lens zoom control device 221 includes a transmission rod 6 and a driving member 7. The transmission rod 6 is located in the outer casing 215 and includes a first end portion 61, a second portion Μ and a sliding hole 63 opposite to the first end portion 61. The sliding hole 63 is disposed at the first end portion Μ, and the / month moving hole 63 can be an elongated hole, and the sliding direction of the boring hole 63 and the trajectory a is not a thousand lights, and the sliding hole 63 is used for the image zooming rocker. In more detail, the extension of the sliding hole 63? Dynamically set the tooth to prevent the image zooming rocker 223 from sliding in the vertical direction of the trace 18 ^ ^ ^ - moving hole 63 to produce an interference transmission cup 6 from the brother-segment 65 and the connection into a '... and the second segment The extension of the 66 is set at the first segment 65 away from the second segment. The blunt portion 62 is disposed at the second segment 66 away from the 钿' and 63 and the first segment of the drive 捍6. :/5 - the end. The second section & of the sliding hole moving rod 6 is parallel to the direction in which the gold is extended. Pass, the extension direction of the hole 63 and the trace 18 are more and more I square = 16 parallel. And slippery angle. - a direction between the core direction 16 has a clip drive member 7 fixedly located on the movable drive jaw 6 along a square of the two sides of the slide hole, which can drive 'for example, the direction of the drive member 7 is not parallel to the direction The shift, or the σ 20 of the drive member 7, can be perpendicular to the projection direction 16, if in the direction 20:, parallel to the projection direction 16. For details, for example, when _~ to 2〇2 10 200830026 I drive member 7 drives the transmission rod 6 from a first position (four) to a second position (as imagined in Figure 1), the same as: line; Shake (4) slide in the sliding hole 63 so that the shadow port = the image is located at the first end (8) of the trace 18 and the _ play bar 223 material 6 is in the second position, the image zooming rocker 223 is at the position::, when the younger brother The second end 182 is opposite to the second end (four) of the sliding hole 63. Therefore, the drive 18 can be combined with the operation button 214 in the following manner: In addition: the extending direction of the π moving hole 63 and the trajectory 18 may also have the other 6 leaves, for example, as shown in Fig. U. 虿 Other directions and the trajectory 18, not parallel, sliding: 1, sliding hole The extension of 63 has an angle, the extension of the sliding hole 63 and the obstruction 18, and the extension between: the second:: the extension - the extension of the lunar opening 63 has an angle between the projections, the trajectory 18, Fish cast, square 6 wide, "direction 16 of the direction of movement 20 can be cast, square two-direction 6-phase vertical, the drive member 7 can also be added to the projection side, the direction;; flat 1 as \ straight' drive 7 Between the moving direction and the trajectory 18, there is a large extension of the first segment 65 of the extending rod 6 of the smashing/month moving hole 63.
