M428877 五、新型說明: 【新型所屬之技術領域】 本創作公開了一種使用於自動送紙裝置中的取紙機構,尤 其涉及一種打印機、掃描儀、複印機和傳真機等辦公設備所用 的取紙機構。 【先前技術】 按,請參閱第一圖至第四圖,目前市面上所揭露的一種取 紙機構包括一機體10’、一取紙模組20’、一第一止擋部214’、 一第二止擋部215’及至少一擋紙件30’。機體10’包括一上蓋 11’,取紙模組20’裝設於機體上,該取紙模組20’包括一取紙 架21’、一分紙元件23’及一取紙元件24’。一第一止擋部214’ 及一第二止擋部215’設於取紙架21’上。擋紙件30’設於取紙 元件24’與分紙元件23’之間,並樞接於上蓋11’上。擋紙件30’ 具有用於擋紙的擋紙部32’及一支撐部34’,支撐部34’可活動 的抵頂於第一止擋部214’以支撐取紙模組20’(如圖三所示), 也可活動的抵頂於第二止擋部215’以限制擋紙件30’旋轉角度 (如-圖 ^^^~戶斤-τρ-)-。_ 惟,上述取紙機構之取紙架21’當上抬至定位而處於預備 放紙的狀態時,擋紙件30’之支撐部34’能夠支撐第一止擋部 214’(如圖二所示),可防止取紙模組20’因外力作用而下擺從 而妨礙放紙。當使用者放紙時,紙張需要克服支撐部34’與第 一止擋部214’之間的摩擦力,因此第一止擋部214’與擋紙件 30’的支撐部34’之間的摩擦力有機會影響到單張紙的進紙,因 為單張紙的推力較小,有可能因為不能克服此摩擦力而不能推 動擋紙件30’的擋紙部32’ ,從而使支撐部34’離開第一止擋 部214’ ;支撐部34’不能離開第一止擋部214’ ,取紙模組20’ 3 M428877 就無法下擺進行取紙動作。而且當取紙機構受到較大外力時, 只要能克服此摩擦力,取紙模組20’就有機會因受碰撞或者機 台的振動而落下,從而不便於放紙操作,進而影響取紙功能。 M428877 【新型内容】 本創作之目的在於克服上述技術中的不足,提供一種便於 放紙操作從而能夠準確可靠地取紙的取紙機構。 為達成上述目的,本創作所提供取紙機構,包括一機體、 一取紙模組、一支撐元件、一套件及一取紙架。取紙架用以連 結分紙元件及取紙元件,取紙模組連接於機體,該取紙模組設 有一取紙元件及一分紙元件;支撐元件樞設於機體上;套件套 設於取紙元件上,可樞轉至一第一位置與一第二位置;其中, 當套件樞轉至第一位置時,支撐元件可抵住套件以支撐取紙模 組;當套件樞轉至第二位置時,套件可從支撐元件上脫離。 如上所述,本創作取紙機構藉由支撐元件透過套件支撐取 紙模組,而非如同習知技術以擋紙件來支撐取紙模組。因而當 取紙模組不作動時,取紙模組由支撐元件所支撐,可防止取紙 模組因外力作用而下擺而妨礙放紙。當取紙時,套件向另一方 向旋轉使得套件脫離支撐元件,因而取紙模組下擺而開始取 紙。相較於習知技術,本創作可避免取紙機構受到外力而下 擺;此外,當使用者放紙時不需要克服擋紙件的力量,從而避 免單張紙不能將擋紙件推開的問題,而便於放紙操作,進而能 夠準確可靠地取紙。 【實施方式】 為詳細說明本創作之技術内容、構造特徵、所達成目的及 功效,以下茲舉例並配合圖式詳予說明。 請參閱第五圖及第六圖,本創作取紙機構一較佳實施例包 括一機體10、一取紙模組20、兩擋紙件30、至少一支撐元件 40及一紙張感測器(圖中未示)。所述機體10具有一上蓋11。 請參閱第六圖及第七圖,所述取紙模組20樞裝於上蓋 5 M428877 11,取紙模組20包括一取紙架21、一分紙輪轴231、一分紙 元件23及一取紙元件24。 所述分紙輪軸231樞裝於上蓋11,分紙輪軸231的右端 與一動力源(圖面未標示)連接以驅動取紙模組20。本實施例 中,動力源由齒輪傳遞,但是,在真正實施時,動力源還包括 馬達及傳動齒輪組等元件,馬達的動力由齒輪傳遞到分紙輪軸 231。 所述分紙元件23可與另一阻擋元件(圖面未標示)共同作 用,用以分離由取紙元件24帶入分紙元件23的多張文件為單 張文件,並繼續帶動此一單張文件往下游前進,所述分紙元件 23可為一分紙皮帶或一分紙輪。所述分紙元件23具有一分紙 輪軸231,該分紙輪軸231上套設一分紙滾輪232,分紙滚輪 232通常以高摩擦係數的材料,譬如以橡膠製成。馬達的動力 傳遞到分紙輪軸231後,再由分紙輪軸231帶動分紙滚輪232 轉動。 請續參照第六圖及第七圖,所述取紙架21連接分紙元件 23及取紙元件24。所述取紙元件24用以接觸並帶動放置於取 紙機構的進紙盤上(圖面未標示)的文件向下游的分紙元件 23移動,所述取紙元件24可為一取紙皮帶或一取紙輪。所述 取紙元件24具有一取紙輪軸241,該取紙輪軸241上套設一 取紙滾輪242,取紙滾輪242通常以高摩擦係數的材料,譬如 以橡膠製成。 取紙架21於取紙元件24 —端設有一擋片27,所述取紙 元件24 —端樞轉地套設有一圓筒狀的套件25,套件25柩套 於取紙輪轴241上,套件25可樞轉至一第一位置與一第二位 置,取紙輪軸241上樞接套件25 —端圓周方向上開設一滑槽 28,套件25 —側端向外凸設形成一止擋片251,套件25上向 6 内延伸形成一彈臂252,彈臂252上凸設形成一卡塊253,卡 塊253抵於滑槽28内,使套件25與取紙輪軸241之間有一定 的摩擦力,套件25與取紙輪軸241之間藉由摩擦力來傳遞動 力,而使得套件25旋轉,取紙架21於取紙元件24與分紙元 件23之間設有一擋塊29。 取紙輪轴241上於取紙滚輪242與套件25之間套設有一 可相對取紙輪軸241旋轉一定角度的推抵件26,推抵件26具 有一環狀帶缺口的固定環261及一從固定環261外側面向外延 伸形成的推抵部262,固定環261樞設於取紙輪軸241上,檔 片27伸入固定環261之缺口處且固定環261可繞著取紙輪軸 241轉動,以使固定環261的缺口兩端可抵頂擋片27,從而限 制推抵件26的旋轉角度。 分紙輪軸231連結於一動力源,並由分紙輪軸231傳遞動 力給分紙元件23,一動力傳遞單元22連接分紙元件23與取 紙元件24,用以將動力由分紙元件23傳達至取紙元件24。於 真正實施時,動力傳遞單元可為一皮帶或齒輪組等。 請參閱第五圖至第七圖,所述擂紙件30樞裝於機體10之 上蓋11,擋紙件/的€7Μ於推抵#16的推抵部262, 擋紙件30具有一樞接部31、一從樞接部31底端向下延伸形 成的擋紙部32與一從樞接部31向上延伸形成的抵擋部33, 抵擋部33可活動地抵頂推抵部262,推抵部262可繞著取紙 輪軸241轉動以活動地抵頂擋紙件30的抵擋部33。 所述支撐元件40 —端樞接於機體10之上蓋11,支撐元 件40具有一支撐部41。當套件25樞轉至第一位置時,支撐 元件40的支撐部41可抵住套件25以支撐取紙模組20,使取 紙模組20保持於上抬後的預備放紙位置。當套件25樞轉至第 二位置時,套件25可從支撐元件40的支撐部41上脫離。 M428877 所述紙張感測器(圖中未標示)樞裝於機體10之上蓋11, 用以偵測進紙盤是否有紙。 本創作取紙機構的工作過程詳述如下: 請參閱第九圖至第十圖,當上一次送紙動作完成後,紙張 準備放入進紙盤之前,系統會由紙張感測器偵測出進紙盤内沒 有紙張。分紙輪軸231會在動力源驅使下反轉(順時針轉),而 帶動取紙模組20前端之取紙元件24上抬至高位,套件25之 止擋片251止擋於支撐元件40的支撐部41上方,從而當取紙 模組20受外力或震動下移時,支撐部41可抵頂於止擋片251 下側,並支撐止擋片251。當套件25之止擋片251順時針轉 動時,若碰觸到支撐元件40之支撐部41左側而停止轉動,取 紙架21會持續上抬,直到止擋片251上抬高於支撐部41(請參 閱第九圖),跨過支撐部41上端;止擋片251持續順時針轉動 直到止擋片251右側抵住支撐部41凹陷部(圖中未標注)而停 止(請參閱第十圖)。此時,進紙盤沒有紙張,取紙模組20位 於預備放紙狀態,藉由支撐元件40抵頂套件25之止擋片251 以支撐取紙模組20,以確保取紙元件24不會受碰撞或者機台 之振動而下移,如此可有效確保使用者在放紙時,取紙模組 20位於預備放纸的高位,纸張不會因取紙模組20下擺而被擋 在取紙元件24前,因而妨礙取紙。 請參閱第十一圖至第十二圖,紙張放置完畢後,使用者透 過按鍵、電腦或其他方式輸入送紙的指令,動力源驅使分紙輪 軸231正轉(逆時針轉),取紙模組20前端下擺,帶動取紙元 件24向下,同時帶動套件25之止擋片251脫離支撐元件40 之支撐部41(請參閱第十一圖),使取紙模組20下移後從而進 行取紙動作,此時取紙元件24帶動推抵件26脫離擋紙件30 之抵擋部33,並且擋塊29抵擋下壓擋紙件30上端突出部, 8 使擋紙部32 @擋紙件3Q逆時針旋轉而勉起,從而使紙張可通 過擔紙件30(請參閱第十二圖)。 *紙張王部通過送紙裝置後,進紙盤内再度沒有紙張時, 紙張感測㈣測出進紙盤内沒有紙張,動力源再度帶動分紙輪 軸別;價時針反轉並帶動取紙架21上抬。當套件25之止擔片 ⑸順時針轉動時,碰觸到支標元件4〇之支樓部41左側而停 止轉動’取紙架21會持續上抬,直到止標片251上抬高於支 樓部41(請參閱第九圖),跨過支擇部4ι上端;止標片2 續順時針轉動直到止擋片251右側抵住支樓㈣凹陷部(圖中 未標注)而停止(請參閱第十圖)。此時,取紙架21上抬至高位, 送紙機構恢復到預備放紙狀態以利下次放紙。 請參閱第十圖,當取紙架21上抬至高位時,止撞片251 右側抵住支撐部41凹陷部,藉*域元件40可擋住套件25 的順時針轉動,支撑元件4G阻擋的力量大於套件25與取紙輪 軸241之間的摩擦力’這時當取紙輪軸241、繼續順時針轉動, 套件25也不會跟著轉動。 一一取紙機構在預備放紙狀態時,藉由 元件40 ^止-私而 取代習知技術中利用擋紙件來支揮取紙模組2()。 件2〇,使其止擋片251旋轉至支樓元件4〇之支樓部41的 方,因而當取紙模組20不作動時’取紙模組2 40支樓’可防止取紙模組2()因外力作用下擺而妨礙蚀。 备取紙時’套件25向另—方向旋轉(逆時針方 〜 :片251旋轉至支揮部41的下方(第十一圖),因而取二 可下擺而開始取紙。相較於習知技術,如此 、 者放紙時需要克服檔紙件30的力量,避免了星 “ 紙件3。推開的問題’因而便於放紙操作,進而能 地取紙。 【圖式簡單說明】 第一圖為習知取紙機構的部分立體分解圖。 第二圖為第一圖所示取紙機構的侧視圖。 第三圖為第一圖所示取紙機構的另一狀態的側視圖。 第四圖為第一圖所示取紙機構的立體圖。 第五圖為本創作取紙機構的側面部分剖視圖。 第六圖為第五圖所示取紙機構之部分立體圖。 第七圖為第五圖所示取紙機構之取紙模組、擋紙件及支撐 元件的分解圖。 第八圖為第五圖所示取紙機構之套件的立體圖。 第九圖為第五圖所示取紙機構之取紙模組上抬至高位的 狀態圖。 第十圖為第五圖所示取紙機構的取紙模組上抬至穩定位 置的狀態圖。 第十一圖為第五圖所示取紙機構的取紙模組上擺或下擺 其中間過程的狀態圖。 第十二圖為第五圖所示取紙機構的取紙模組開始取紙的 狀態圖。 【主要元件符號說明】 機體 10 上蓋 11 止擋塊 12 取紙模組 20 取紙架 21 分紙元件 23 分紙輪軸 231 分紙滾論 232 取紙元件 24 取紙輪軸 241 取紙滾論 242 套件 25 M428877 止擋片 251 卡塊 253 固定環 261 擋片 27 擋塊 29 極接部 31 抵擋部 33 支撐部 41 彈臂 252 推抵件 26 推抵部 262 滑槽 28 擋紙件 30 擋紙部 32 支撐元件 40M428877 V. New description: [New technical field] The present invention discloses a paper take-up mechanism used in an automatic paper feeding device, and particularly relates to a paper take-up mechanism used in office equipment such as a printer, a scanner, a copying machine, and a facsimile machine. . [Prior Art] According to the first to fourth figures, a paper take-up mechanism disclosed in the prior art includes a body 10', a paper take-up module 20', a first stop portion 214', and a The second stopping portion 215' and the at least one paper stopper 30'. The body 10' includes an upper cover 11', and the paper take-up module 20' is mounted on the body. The paper take-up module 20' includes a paper take-up frame 21', a paper separation member 23', and a paper take-up member 24'. A first stop portion 214' and a second stop portion 215' are provided on the pickup holder 21'. The paper stopper 30' is disposed between the paper take-up member 24' and the paper-dividing member 23' and pivotally connected to the upper cover 11'. The paper stop 30' has a paper stop 32' for blocking paper and a support portion 34'. The support portion 34' is movable against the first stop portion 214' to support the paper take-up module 20' (eg As shown in FIG. 3, it is also movable to abut against the second stopping portion 215' to limit the rotation angle of the paper stopper 30' (for example, -^^^~ 斤-τρ-). _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ As shown in the figure, the paper take-up module 20' can be prevented from swaying due to an external force to hinder the paper discharge. When the user puts the paper, the paper needs to overcome the friction between the support portion 34' and the first stop portion 214', and thus between the first stop portion 214' and the support portion 34' of the paper stopper 30'. The friction has an opportunity to affect the paper feed of the sheet, because the thrust of the sheet is small, and it is possible that the paper stopper 32' of the paper stopper 30' cannot be pushed because the frictional force cannot be overcome, so that the support portion 34 is provided. 'Leaving the first stop portion 214'; the support portion 34' cannot leave the first stop portion 214', and the paper take-up module 20' 3 M428877 cannot perform the paper take-up action. Moreover, when the paper take-up mechanism is subjected to a large external force, as long as the frictional force can be overcome, the paper take-up module 20' has the opportunity to fall due to the collision or the vibration of the machine table, thereby making it inconvenient to put the paper, thereby affecting the paper take-up function. . M428877 [New content] The purpose of this creation is to overcome the deficiencies in the above-mentioned techniques and to provide a paper take-up mechanism that facilitates paper feeding operations and enables accurate and reliable paper take-up. In order to achieve the above object, the present invention provides a paper taking mechanism including a body, a paper take-up module, a supporting component, a kit and a paper take-up rack. The paper take-up frame is used for connecting the paper separating component and the paper picking component, and the paper picking module is connected to the body, the paper picking module is provided with a paper taking component and a paper separating component; the supporting component is pivoted on the body; the sleeve is sleeved on the The paper taking member is pivotable to a first position and a second position; wherein, when the sleeve is pivoted to the first position, the support member can abut the sleeve to support the paper take-up module; when the kit pivots to the first In the two positions, the kit can be detached from the support member. As described above, the present paper taking mechanism supports the paper take-up module through the support member through the support member instead of supporting the paper take-up module with the paper stopper as in the prior art. Therefore, when the paper take-up module is not actuated, the paper take-up module is supported by the support member, which prevents the paper take-up module from swaying due to an external force and hindering the paper feed. When the paper is taken, the kit is rotated in the other direction to disengage the kit from the support member, so the pickup module hem is used to start the pickup. Compared with the prior art, the present invention can prevent the paper taking mechanism from being subjected to external force and the hem; in addition, when the user puts paper, it is not necessary to overcome the force of the paper blocking member, thereby avoiding the problem that the sheet of paper cannot push the paper blocking member away. , and it is easy to put paper, so that the paper can be taken accurately and reliably. [Embodiment] In order to explain in detail the technical contents, structural features, achieved goals and effects of the present invention, the following is a detailed description with reference to the drawings. Referring to the fifth and sixth figures, a preferred embodiment of the present paper taking mechanism includes a body 10, a paper take-up module 20, two paper stops 30, at least one support member 40 and a paper sensor ( Not shown in the figure). The body 10 has an upper cover 11. Referring to the sixth and seventh figures, the paper take-up module 20 is pivotally mounted on the upper cover 5 M428877. The paper take-up module 20 includes a paper take-up frame 21, a paper feed wheel shaft 231, a paper separation component 23, and A paper take-up element 24. The paper separation wheel shaft 231 is pivotally mounted on the upper cover 11, and the right end of the paper separation wheel shaft 231 is coupled to a power source (not shown) to drive the paper take-up module 20. In the present embodiment, the power source is transmitted by the gear, but in the actual implementation, the power source further includes components such as a motor and a transmission gear set, and the power of the motor is transmitted from the gear to the separation roller shaft 231. The paper separating member 23 can cooperate with another blocking member (not shown) to separate a plurality of documents brought into the paper separating member 23 by the paper taking member 24 into a single document, and continue to drive the single sheet. The sheet of paper advances downstream, and the sheet separating member 23 can be a paper separation belt or a paper separation roller. The separation member 23 has a separation roller shaft 231, and a separation roller 232 is disposed on the separation roller shaft 231. The separation roller 232 is usually made of a material having a high friction coefficient, such as rubber. After the power of the motor is transmitted to the separation roller shaft 231, the separation roller shaft 231 drives the separation roller 232 to rotate. Referring to the sixth and seventh figures, the paper take-up frame 21 is connected to the paper separating member 23 and the paper picking member 24. The paper take-up element 24 is configured to contact and drive a document placed on the paper feed tray of the paper take-up mechanism (not shown) to move to the downstream paper separation element 23, and the paper take-up element 24 can be a paper take-up belt Or take a paper wheel. The paper take-up element 24 has a take-up reel shaft 241, and a take-up roller 242 is sleeved on the take-up reel shaft 241. The take-up reel 242 is usually made of a material having a high coefficient of friction, such as rubber. The paper take-up frame 21 is provided at the end of the paper take-up member 24 with a baffle 27, and the paper-receiving member 24 is pivotally sleeved with a cylindrical sleeve 25, and the sleeve 25 is sleeved on the take-up reel shaft 241. The sleeve 25 is pivotable to a first position and a second position, and a sliding slot 28 is defined in the circumferential direction of the pivoting sleeve 25 on the pickup shaft 241. The sleeve 25 protrudes outwardly to form a stop piece. 251, a sleeve arm 252 is formed on the sleeve 25, and a latching block 253 is formed on the elastic arm 252. The latching block 253 is inserted into the sliding slot 28 to ensure a certain relationship between the sleeve 25 and the pickup shaft 241. The frictional force is transmitted between the kit 25 and the pickup shaft 241 by frictional force to rotate the sleeve 25, and the pickup 21 is provided with a stopper 29 between the pickup member 24 and the separation member 23. The pickup shaft 241 is disposed between the pickup roller 242 and the sleeve 25 with a pushing member 26 that is rotatable relative to the pickup shaft 241. The pushing member 26 has an annular notched fixing ring 261 and a The pushing portion 262 is formed on the outer side of the fixing ring 261, and the fixing ring 261 is pivoted on the take-up wheel shaft 241. The flap 27 extends into the notch of the fixing ring 261 and the fixing ring 261 can rotate around the take-up wheel shaft 241. So that both ends of the notch of the fixing ring 261 can abut against the top piece 27, thereby limiting the angle of rotation of the pushing member 26. The separation roller shaft 231 is coupled to a power source, and transmits power to the paper separation member 23 by the separation roller shaft 231. A power transmission unit 22 connects the paper separation member 23 and the paper pickup member 24 for transmitting power to the paper separation member 23. To the paper take-up element 24. In the actual implementation, the power transmission unit can be a belt or a gear set or the like. Referring to FIG. 5 to FIG. 7 , the paper picking member 30 is pivotally mounted on the upper cover 11 of the body 10 , and the paper blocking member 的 is pushed against the pushing portion 262 of the #16. The paper blocking member 30 has a pivot. a blocking portion 31, a paper blocking portion 32 extending downward from a bottom end of the pivoting portion 31, and a resisting portion 33 extending upward from the pivoting portion 31. The resisting portion 33 is movable against the pushing portion 262. The abutting portion 262 is rotatable about the pickup shaft 241 to movably abut the abutting portion 33 of the sheet stopper 30. The support member 40 is pivotally connected to the upper cover 11 of the body 10. The support member 40 has a support portion 41. When the kit 25 is pivoted to the first position, the support portion 41 of the support member 40 can be pressed against the sleeve 25 to support the pickup module 20, so that the pickup module 20 is held in the raised pre-release position. When the kit 25 is pivoted to the second position, the sleeve 25 is detachable from the support portion 41 of the support member 40. The paper sensor (not shown) of M428877 is pivotally mounted on the upper cover 11 of the body 10 for detecting whether the input tray has paper. The working process of the authoring paper picking mechanism is detailed as follows: Please refer to the ninth to tenth drawings. After the last paper feeding action is completed, the system will be detected by the paper sensor before the paper is ready to be placed in the input tray. There is no paper in the input tray. The paper separation wheel shaft 231 is reversed (clockwise rotation) under the power source drive, and the paper take-up element 24 at the front end of the paper take-up module 20 is raised to a high position, and the stop piece 251 of the set 25 stops at the support member 40. Above the support portion 41, when the paper take-up module 20 is moved downward by an external force or vibration, the support portion 41 can abut against the lower side of the stop piece 251 and support the stop piece 251. When the stop piece 251 of the sleeve 25 rotates clockwise, if it touches the left side of the support portion 41 of the support member 40 and stops rotating, the paper take-up frame 21 will continue to be lifted until the stop piece 251 is lifted higher than the support portion 41. (Please refer to the ninth figure), across the upper end of the support portion 41; the stop piece 251 continues to rotate clockwise until the right side of the stop piece 251 abuts against the recessed portion of the support portion 41 (not shown) (see the tenth figure) ). At this time, the paper feed tray has no paper, and the paper take-up module 20 is in the pre-release state, and the support member 40 abuts the stop piece 251 of the set 25 to support the paper take-up module 20 to ensure that the paper take-up element 24 does not It is effectively moved by the collision or the vibration of the machine. This ensures that when the user puts the paper, the paper take-up module 20 is at the high position of the preparatory paper, and the paper is not blocked by the hem of the paper take-up module 20. The front of the paper element 24 thus hinders the pickup. Please refer to the 11th to 12th drawings. After the paper is placed, the user inputs the paper feed command through the button, computer or other means. The power source drives the separation roller shaft 231 to rotate forward (counterclockwise) and take the paper mold. The front end hem of the group 20 drives the paper take-up element 24 downward, and simultaneously drives the stop piece 251 of the set 25 away from the support portion 41 of the support member 40 (refer to FIG. 11), so that the paper take-up module 20 is moved down. The paper taking operation 24 drives the pushing member 26 to disengage the abutting portion 33 of the paper stopper 30, and the stopper 29 abuts against the upper end of the lower paper stopper 30, 8 causes the paper stopping portion 32 The 3Q is rotated counterclockwise to pick up so that the paper can pass through the paper carrying member 30 (see Figure 12). *When the paper king passes the paper feeding device and there is no paper in the input tray again, the paper senses (4) that there is no paper in the input tray, and the power source drives the separation roller shaft again; the price hour reverses and drives the paper take-up holder 21 lifted up. When the end piece (5) of the sleeve 25 rotates clockwise, it touches the left side of the branch portion 41 of the branch member 4〇 and stops rotating. The take-up tray 21 will continue to be lifted until the stop plate 251 is lifted above the support. The floor portion 41 (please refer to the ninth figure), spans the upper end of the cutting portion 4ι; the stop tab 2 continues to rotate clockwise until the right side of the stop piece 251 is pressed against the recessed portion of the branch (four) (not shown) and stops (please See the tenth figure). At this time, the paper take-up frame 21 is raised to a high position, and the paper feeding mechanism is restored to the preliminary paper discharge state to facilitate the next paper discharge. Referring to the tenth figure, when the paper take-up frame 21 is raised to the upper position, the right side of the stopper piece 251 is pressed against the recessed portion of the support portion 41, and the field element 40 can block the clockwise rotation of the set 25, and the support member 4G blocks the force. It is larger than the friction between the kit 25 and the pickup shaft 241. At this time, when the pickup shaft 241 continues to rotate clockwise, the kit 25 does not rotate. When the paper take-up mechanism is ready for the paper-feeding state, the paper-removing module 2 () is replaced by the paper-stopping member in the prior art by the component 40. The piece 2 is rotated such that the stop piece 251 is rotated to the side of the branch portion 41 of the branch member 4, so that when the paper take-up module 20 is not actuated, the 'pickup module 2 40 branch' prevents the paper take-up mode Group 2 () occupies the hem due to external force. When the paper is ready, the kit 25 rotates in the other direction (counterclockwise ~: the sheet 251 is rotated below the branch 41 (the eleventh figure), so the second hem can be taken to start the paper picking. Compared with the conventional one The technology, in this way, the paper needs to overcome the force of the paper sheet 30 when the paper is put on, avoiding the star "paper 3, the problem of pushing open" and thus facilitating the paper feeding operation, and then the paper can be taken.
