图3为图1中闸门与齿条板一体成型的结构示意图；
图4为图1中滑槽板的结构示意图。
本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明，本发明中的技术特征在不相互矛盾的情况下都可以任意组合。
纸币识别设备内部设置有用于辨识纸币的识别传感器。该识别传感器一般通过微小的区别变量来识别纸币。因此，该识别传感器需要保持干净清洁，才能使得纸币识别设备保持良好的辨识正确率。通常纸币识别设备的纸币通道与外界直接连通，这导致大量的灰尘颗粒等外物可以自由的进入纸币识别设备。为了保持良好的辨识正确率，通常会定时拆卸该识别传感器，并清洁其内部的识别传感器。
为了减少清洗，减少拆卸次数，延长设备的保持良好辨识正确率的时间。本实施例提供了一种纸币识别设备，请参看图1，图1示出了优选实施例的局部截面示意图。
本纸币识别设备，用于自助终端，包括壳体1，壳体1上包括连通壳体1内外的一条纸币通道11。纸币识别设备包括设置于壳体1内的可活动的活动门装置，该活动门装置用于开放或关闭纸币通道11。
本实施例所提供的纸币识别设备，增设活动门装置使得纸币识别设备的纸币通道11可以按需开放和关闭，从而使得纸币识别设备与外界的连通由不间断连通，改变为间断连通。由于纸币识别设备与外界为间断连通，从而可以减少了外部灰尘等外物进入纸币识别设备内，进而减少了纸币识别设备内部的识别传感器被污染的概率，即延长了纸币识别设备的拆卸清洁周期，增加了纸币识别设备的正常工作时间。
活动门装置可以设置为多种，其中，闸门式活动门装置具有所需驱动力大的特点，从而具有一定的防止暴力打开性能。因此本实施例中，优选该活动门装置为闸门式活动门装置。
请结合参看图1至图4，该活动门装置包括导向装置及与该导向装置滑动配合的闸门22。具体地，导向装置包括具有滑槽212的滑槽板21，闸门22上具有与该滑槽212配合的滑键221。滑槽板21固设于壳体1上，闸门22的滑键221于该滑槽21内滑移。
请再次参看图1，具体地，本实施例中，壳体1上具有连通纸币通道11的一个过孔12，该过孔12位于纸币通道11的中段。闸门22通过该过孔12滑入至该纸币通道11中。该纸币通道11通过该闸门22的滑动以实现关闭或开放。当然在其他实施例中也可以不设置该过孔12，即闸门22也可以直接挡于所述纸币通道11两端的通道口处。
本实施例中，闸门22通过上下方向的移动以开放或关闭纸币通道11，具体地，滑槽212为沿着上下方向延长。当然，在其他实施例中，还可以设置闸门22通过左右移动以开放或关闭纸币通道11，即滑槽212为沿着左右方向延长。
由于闸门式的活动门装置需要较大的驱动力来驱动，因此，优选地采用机电装置来驱动该活动门装置。同时，由于齿轮齿条传动的结构简单、可靠性好，本实施例优选采用齿轮齿条来传动驱动力。
具体地，本纸币识别设备包括一个驱动电机3及控制该驱动电机3的电控装置4。该驱动电机3固定于壳体1上，且该驱动电机3的转轴31上固装有主动齿轮32。闸门22上固定连接有一个齿条231以与主动齿轮32啮合。具体地，本实施例中，该齿条231设于一个齿条板23的一板面上，该齿条板23与闸门22固定连接，即闸门22与齿条板23一体成型。在工作中，该电控装置4接收到开放或关闭纸币通道11的控制信号后，传递控制信号至驱动电机3。驱动电机3接收信号后驱动主动齿轮32正向或逆向转动，从而带动具有齿条231的齿条板23，齿条板23再带动闸门22作开闸或关闸动作，从而实现纸币通道11的开放或关闭。
本实施例中，齿条231设于齿条板23上，齿条板2 3再与闸门22固定连接，在其他实施例中，还可以直接将齿条231设于闸门22上。当然，在本实施例中，采用齿轮齿条传动，在其他实施例中，还可以采用螺杆式传动，凸轮式传动等来带动闸门22作开闸或关闸动作。在本实施例中，采用提供转动运动的驱动电机驱动闸门22，在其他实施例中，也可以采用液压甭驱动闸门22或采用电动推杆驱动闸门22或其他形式的机电设备驱动闸门22。
为了能够使得齿轮齿条传动的闸门22具有自锁效果，即在重力或外力的作用下闸门22不会移动，优选地，本实施例中，驱动电机3为减速电机，即该驱动电机3具有减速组件。本领域技术人员了解，由于减速组件的特性，驱动电机3对齿条231的力将被放大，同时齿条231对驱动电机3的力将被缩小。因此导致齿条231不能带动减速电机3转动，而仅能由减速电机3驱动齿条231，即达到了自锁的效果。
上述电控装置4所接收到的用于开放或关闭纸币通道11的控制信号的来源可以为多种，比如用于供使用者按压以产生信号的按钮，或感应到人辐射的红外线时产生信号的红外传感器等。本实施例中，为了能够使得本纸币识别设备自动化程度更高、开关闸门更准确，优选本纸币识别设备包括可以检测纸币的检测器。具体地，本纸币识别设备中，以闸门22为界，定义纸币通道11区分为内段和外段，其外端为靠近纸币识别设备外部的一段。本纸币识别设备包括与电控装置4电连接的纸币检测器5。该纸币检测器5与壳体1固定连接，该纸币检测器5的检测头设于纸币通道11的外段，以检测使用者所投的纸币。该纸币检测器5检测到纸币通道11的外段的纸币后，传递信号至电控装置4，电控装置4接收到该信号后再控制驱动电机3的转动以带动闸门22开闸；当该纸币检测器5检测到纸币离开纸币通道11的外段后，传递信号至电控装置4，电控装置4接收到该信号后再控制驱动电机3反向转动以带动闸门22关闸。
具体地，本实施例中，纸币检测器5为一种红外传感器。该红外传感器包括分开的发射端和接收端。在没有纸币的情况下，该发射端所发出的红外线被接收端所接收。在具有纸币的情况下，该发射端所发出的红外线被纸币所遮挡，则接收端不能接收到红外信号，从而产生信号至电控装置4。
本实施例中，该纸币检测器5的红外发射端与红外接收端皆固设于纸币通道11的上壁，即纸币检测器5的红外发射端从纸币通道11的上壁向下发射红外线。本纸币识别设备包括导光装置，该导光装置于纸币通道11的下壁中对应纸币检测器5的位置设置，即设置在纸币检测器5的下方且能接收到该红外线。该导光装置的入光口对准纸币检测器5的红外发射端以接收红外线，导光装置的出光口对准纸币检测器5的红外接收端以返回红外线。在大部分情况下，纸币检测器5的发射端发出的红外线竖穿纸币通道11到达导光装置，再经导光装置折射后射入纸币检测器5的接收端；在纸币存在于纸币通道11的情况下，纸币会遮挡该红外线，从而使得纸币检测器5的接收端接收不到红外线，从而产生信号至电控装置4。
由于纸币的纸张为特制纸张，对红外线具有较强的吸收遮蔽效果。纸币检测器5利用纸币的该特性而采用红外传感器，从而具有对纸币或异物区分的功能，从而结构简单，成本低的实现辨别纸币的功能。当然在其他实施例中，也可以设置纸币检测器5的红外发射端与红外接收端分别位于纸币通道11的上壁和下壁，即红外发射端直接对准红外接收端。
为了更好地驱动闸门22运动，优选本纸币识别设备具有一个定位装置来定位该闸门22的位置。
具体地，本实施例中，该定位装置包括与电控装置4电连接的上位置检测器61和下位置检测器62。该两个位置检测器61、62之间的间距和闸门22的运动行程相同。闸门22上有一个突出221，该突出221与该两个位置检测器61、62配合。
在闸门22向上运动时，突出222移动至靠近纸币通道11的上位置检测器61，该上位置检测器61检测到突出222，则传递信号至电控装置4。电控装置4接收到该信号时则停止驱动电机3的转动，从而停止闸门22的移动。同理，在闸门22向下运动时，突出222移动至远离纸币通道11的下位置检测器62，该下位置检测器62检测到突出222，则传递信号至电控装置4。电控装置4接收到该信号时则停止驱动电机3的转动，从而停止闸门22的移动。
具体地，本实施例中，两个位置检测器61、62为另一种红外传感器。该红外传感为自带发射端和接收端的红外传感器。当发射端所发射的红外光被突出222所遮挡而反射时，接收端则接收到红外信号，从而发送信息至电控装置4。
当然，在本实施例中，定位装置为两个位置检测器61、62，在其他实施例中，还可以设置机械触点式装置来实现定位的功能，即闸门22在移动中会触动机械式开关，从而产生控制信号以停止闸门22的移动。
由于定位装置有可能会出现失效的情况，因此优选具有另一种独立的机构来对闸门的行程进行限制。在本实施例中，优选地，闸门22上有限位键223，同时滑槽板21上有限位槽212。该限位槽212的长度略大于闸门22的运动行程，且限位槽212的长度方向平行于闸门22的移动方向，从而限定闸门22的极限位置。即当闸门22在上位置检测器61与下位置检测器62之间移动（额定行程内移动）时，闸门22不受限位槽212的影响；而闸门22向上移动至超过上位置检测器61，该闸门22上的限位键223会抵住限位槽212的一端；或闸门22向下移动至超过下位置检测器62时，该闸门22上的限位键223会抵住限位槽212的另一端，从而实现对该闸门22极限位置的限定。
活动门装置可以是多种形式，本实施例仅以闸门式活动门装置为例，进行详细说明。
在其他实施例中，活动门装置还可以为旋转门式。比如，该活动门装置包括旋转门，该旋转门包括门体及设于该门体上的旋转轴。该旋转门通过该旋转轴固设于该纸币通道11内。纸币通道11通过该活动门装置的旋转以实现关闭或开放。
该活动门装置的驱动方式可以是使用者投入纸币时，通过纸币抵开该活动门装置。也可以是设有一个按钮及与该按钮连接的连杆结构。按下该按钮后，与该按钮连接的连杆结构顶开该活动门装置。
当没有使用者使用该活动门装置时，该活动门装置可以在重力的作用下回弹至关闭或开放该纸币通道11的位置。或者该活动门装置还设有回弹件，该回弹件连接于活动门装置与该壳体上，用以产生回弹力。在该回弹力使得活动门装置回弹至关闭或开放该纸币通道11的位置。
或者进一步的，该活动门装置设有机电设备及传动设备以驱动该旋转门；或者在上述机电设备的基础上，继续加装检测设备以实现自动化操作等。
本发明还提供了一种自助终端，包括纸币识别设备。其中，该纸币识别设备采用上述本发明所提供的纸币识别设备。其具体结构可以参看上述本发明实施例说明，在此不再赘述。
以上所述仅为本发明的优选实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
