The maximum light transmittance; the light-transmitting part 108 of the current side panel, the miscellaneous 11G, the light-transparent part of the rear side panel, and the shading #110 are completely staggered, and the full shading effect can be obtained. The top rail 102, the bottom rail, and the curtain 1〇6 are connected to each other. 120B1 is to drive the curtain 1〇6 displacement, and the roller blind 1〇0 is provided with a driving mechanism 2 and a reel-roller 122 and actuation The member 112 is pivotally connected to the inner side of the top rail 1 102, and a driving wheel 124 is fixed to one end of the roller blind 1 . The surface of the reel drum m is provided with a card slot m for snapping. The first end 128A of the panel touch is provided with _13 (), so that the first end position and the reel, the circumference of the driving wheel 124 is provided with a plurality of grooves 132. The actuating member 112 can be a closed rope And a plurality of beads 134 are disposed, wherein the ball 134 can be engaged with the groove 132 of the driving wheel 124. By pulling the actuating member 112, the 124 and the reel 122 can be driven. The moving wheel continues to refer to Fig. 2, and the top rail 1〇2 is also provided with a fixing member 14〇 to fix the partial panel 1〇6 (i.e., the top end portion of the rear side panel 106B). According to this embodiment, the fastening member 140 includes, for example, a latching groove 142 is disposed on the inner surface of the top row 1 〇 2 on the surface above the reel 122. Through the engaging groove 142 of the fastening member 14 ,, a part of the curtain at the top end of the rear side panel 1 〇 6B can be engaged 1〇6, and the second end 128B of the curtain 106 protrudes from the fastener 14〇. An elongated rod 144 can also be snapped into the engaging groove 142 to clamp a portion of the curtain 106 in the engaging groove 142. To ensure that the front and rear side panels 106A and 106B remain intimately engaged during operation, the fasteners 140 can be disposed about a vertical line extending approximately proximate the peripheral surface of the spool 122. Therefore, regardless of the adjusted position of the curtain 106, the front and rear side panels 106A and 106B can be kept in close contact to prevent the curtain panel 1〇6 from completely covering light leakage. Continuing to refer to FIG. 2, the bottom rail 1〇4 may include an obstructing housing 15〇 and a 201238536 rod 152.

It is worth noting that the invention is not limited to the foregoing embodiments, but can also be implemented by different structures. Fig. 4 is a side elevational view showing a roller blind according to another embodiment of the present invention, the main difference from the foregoing embodiment being the structural design of the fastener. The fastener 240 used in this embodiment includes, for example, an extension arm 242. The extension arm 242 is in contact with the inner side of the top rail 1〇2 on the upper surface of the spool 122. One end of the extension arm 24+2 may be provided with a blunt groove 244 for engaging the partial curtain 106 and allowing the second end 128B of the curtain 106 to protrude from the fastening member 24''. As with the previous embodiment, an elongated rod 246 can be snapped into the engagement groove 244 to clamp the portion of the curtain panel 106 within the engagement groove 244. The extension arm 242 is coupled to the top rail 1〇2 via a pivot joint 248, wherein the pivot joint 248 is located above the spool 122 and the extension arm 242 extends downwardly from the pivot joint 248. The pivotal connection 248 is provided with a hook body 252 at one end of the extension arm 2, and a corresponding fishing portion 254 is provided on the surface of the top rail 102. The extension arm 242 is swingable relative to the top rail 102 by the operative connection of the hook 252 to the hook 254. Depending on the adjusted height of the bottom rail 104, the partial curtains 106 that are retracted on the reel 122 may have different thicknesses, and the pivotal joints 248 may continuously bias the arms 242 toward the position adjacent the reels i22 for The rear side panel i % a is maintained in close contact with each other. As with the previous embodiment, the fastener 240 has a locked-off state. When the secure member 240 is in the locked state, the partial curtain 1'6' can be clamped through the groove to fix the top end of the rear side panel 106B. The second end 128B of the secret can overcome the static friction force that the partial curtain touches the card, so as to turn the fastener 24 into a release state, thereby allowing the second end 128B to be relatively fixed relative to the fastener. Displacement 'to adjust the length of the second end bile extending from the fastener. Since the size of the window is not -, the bottom of the curtain 1 〇 6 must be aligned with the lower edge of the window. With the pulling operation of the second end 12, 201238536 will drive the front and rear side plates and 106B displacement, so that the bottom track just slightly up to the bottom edge of the window frame, and the shading area of the front side hall A is 0 The light-shielding noise 11 相对 with respect to the rear side plate 106B is completely staggered to obtain a full light-shielding effect. As shown in Fig. 5, if the user wants to completely open the roller blind 1〇〇, the roller 122 can be driven by the pull 112 to make the reel 122 retract the curtain 106, and the J road 104 is located adjacent to the top road 1 〇 2 location. When the roller blind is in the two open state, the extension arm 242 can resist a portion of the blade 106 wound on the spool 122 and protrude from the rear side of the top rail 1〇2. Fig. 6 shows a modified embodiment of the bull firmware 240. The second end 128? is also = the direction R is adjusted to be attached to the outer side surface 242a of the extension arm 242. According to the regulation, the outer side surface 242A of the extension arm 242 is provided with, for example, a double-sided adhesive tape, a damper feed, and a second end leg of the genus, to prevent the length of the second 242 from being vertically downward. However, the present invention is capable of extending the portion of the extension arm 242.
