該驅動件90架設於該基架60之該二滑軌支撐塊66上，且各該驅動件90之兩側底面分別延伸有一凸塊92而位於對應之兩個推板721a、721b之間。The driving member 90 is disposed on the two sliding rail supporting blocks 66 of the base frame 60, and a bottom surface of each of the driving members 90 extends with a protrusion 92 between the corresponding two pushing plates 721a and 721b.
藉此，當取紙裝置收到命令，需要進行紙張供給程序時，請參閱圖10及圖11，該輪座72會先受驅動而向下擺動；此時，該輪座72上之推板721a將壓推該驅動件90上對應之凸塊92，使得該驅動件90受推抵而移動，而使得該二擋紙器80之鎖件84會離開該窄槽部681進入寬槽部682，此時，該二擋紙件82未受到任何拘束而可自由轉動。Therefore, when the paper picking device receives the command and needs to perform the paper feeding process, referring to FIG. 10 and FIG. 11, the wheel base 72 is first driven to swing downward; at this time, the push plate on the wheel base 72 The 721a will push the corresponding protrusion 92 on the driving member 90, so that the driving member 90 is pushed and moved, so that the locking member 84 of the second paper stopper 80 will leave the narrow groove portion 681 and enter the wide groove portion 682. At this time, the second paper stopper 82 is freely rotated without being restrained.
紙張供給程序結束後，該輪座72會向上移動回到原先位置，而該輪座72上之推板721b將壓推該驅動件90之凸塊92，進而帶動該驅動件90回到紙張供給程序執行前之位置，使該鎖件42重新進入窄槽部681中，進而達到前述各實施例的功能與作動方式。After the paper feeding process is finished, the wheel base 72 will move back to the original position, and the push plate 721b on the wheel base 72 will push the projection 92 of the driving member 90, thereby driving the driving member 90 back to the paper supply. The position before the execution of the program causes the lock member 42 to re-enter the narrow groove portion 681, thereby achieving the functions and actuation modes of the foregoing embodiments.
綜合以上所述可得知，本發明利用擋紙器上的鎖件與限制部結合來作為固定擋紙器的手段。如此不但可確實固定擋紙器，且無需要以複雜的結構來達成固定與解固定擋紙器的目的。In summary, as described above, the present invention utilizes a lock member on the paper stopper to be combined with the restricting portion as a means for fixing the paper stopper. In this way, not only can the paper stopper be fixed, but also the purpose of fixing and unfastening the paper stopper is not required in a complicated structure.
以上所述僅為本發明較佳可行實施例而已，舉凡應用本發 明說明書及申請專利範圍所為之等效結構變化，理應包含在本發明之專利範圍內。The above description is only a preferred embodiment of the present invention, and the application of the present invention is applicable. The equivalent structural changes of the specification and the scope of the patent application are intended to be included in the scope of the invention.
