Description
显影剂供应容器 技术领域 Developer supply container
本发明涉及可拆卸地安装在成像装置中的用于提供显影剂的显影剂供应 容器, 该成像装置可以是电摄影型或者静电记录型, 例如复印机、打印机、传 真机或类似设备。 背景技术 The present invention relates to a developer supply container for providing a developer detachably mounted in an image forming apparatus, which may be of an electrophotographic type or an electrostatic recording type such as a copying machine, a printer, a facsimile machine or the like. Background technique

The developer supply container can be divided into two types in a different manner, one is a primary type developer supply container, and when the developer is replenished, the developer in the developer supply container is once put into the developer of the image forming apparatus main unit. The receiving portion; the other is a fixed type developer supply container from which the developer is gradually supplied into the image forming apparatus until the developer in the container is exhausted. The latter requires a relatively long period of time to place the developer container in the developing device.
为减小成像装置体积的需要,新近的趋势是采用固定型容器。为防止在更 换显影剂容器时使遗留在容器中的显影剂从排放口散落出,通常在显影剂排放 口配置一密封用的活门构件。 In order to reduce the size of the imaging device, a recent trend is to use a fixed type container. In order to prevent the developer remaining in the container from being scattered from the discharge port when the developer container is replaced, a shutter member for sealing is usually disposed at the developer discharge port.
现有一种显影剂供应容器,包括设在显影剂排放口的活门构件,设在容器 主体一端部的转动构件,在转动构件及活门构件上均设有齿轮。当显影剂供给 容器放置在成像装置主组件中时,通过成像装置主组件中的一传动部件与转动 构件及活门构件上的齿轮之间的配合,旋转转动构件的旋转驱动力被传递给活 门构件, 从而实现显影剂排放口的开启和关闭。 There is a developer supply container comprising a shutter member provided at a developer discharge port, a rotary member provided at one end portion of the container body, and gears provided on both the rotary member and the shutter member. When the developer supply container is placed in the main assembly of the image forming apparatus, the rotational driving force of the rotary rotating member is transmitted to the shutter member by the cooperation between a transmission member in the main assembly of the image forming apparatus and the gear on the rotary member and the shutter member Thereby opening and closing of the developer discharge port.
为了限制可转动部件沿打开活门构件的方向转动,名称为《显影剂供应容 器》 的 CM460901A号中国发明专利申请公开一种显影剂供给容器, 其进一步 包括一限制构件,用于限制可转动构件沿打幵活门构件方向转动,它包括一个 与可转动构件成一体并且基本上沿可转动构件的关闭转动方向延伸的延长部 分和一个从延长部分伸向主组件的、 用于抵靠主体上的止动突起的限制突起。 In order to limit the rotation of the rotatable member in the direction of opening the shutter member, the Chinese Patent Application No. CM460901A entitled "Developer Supply Container" discloses a developer supply container further comprising a restricting member for restricting the rotatable member along The slamming shutter member is directionalally rotated and includes an extension portion integral with the rotatable member and extending substantially in a closing rotational direction of the rotatable member and a portion extending from the extension portion toward the main assembly for abutting against the main body The protrusions of the movement protrusions.
上述显影剂供给容器存在以下问题,第一是传动转动驱动力的齿轮在相互 配合时经常打滑, 容易造成不能打开 /关闭活门构件, 或打开 /关闭不到位; 第
二是零件数目较多,造成装配步骤多以及制造成本相对较高;第三是在运输过 程中, 限位构件容易被不经易地解除, 造成容器主体泄漏显影剂。 发明内容 The above developer supply container has the following problems. The first is that the gears that transmit the rotational driving force often slip when they cooperate with each other, which tends to cause the shutter member to be opened/closed, or the opening/closing is not in place; Second, the number of parts is large, resulting in many assembly steps and relatively high manufacturing costs. The third is that during the transportation process, the limiting members are easily released indiscriminately, causing the container body to leak the developer. Summary of the invention

At this time, the locking projection 4d is ejected from the stopper projections 8a, 8b, and the lock is automatically opened. At this time, by rotating the grip portion 4b of the shutter member 4 in the direction in which the developer discharge port 3 is opened (Ya direction), the shutter portion 4a can be rotated to open the developer discharge port.
拆卸时, 沿关闭显影剂排放口方向 (Yb方向) 旋转抓握部分 4b, 显影剂 排放口被关闭,沿 Xb方向向外拉出显影剂供应容器的同时,解锁突起 4e失去 与成像装置中挡块的接合, 锁定突起 4d抵在止动突起 8a、 8b中间, 活门构件 4被锁定。 此时拆下显影剂供应容器, 容器内残留的显影剂也不会泄露出, 从 而防止污染显影装置及操作者的手。 When disassembling, the grip portion 4b is rotated in the direction of closing the developer discharge port (Yb direction), the developer discharge port is closed, and the developer supply container is pulled outward in the Xb direction, and the unlocking projection 4e is lost with the image forming device The engagement of the blocks, the locking projections 4d abut against the stop projections 8a, 8b, and the shutter member 4 is locked. At this time, the developer supply container is removed, and the developer remaining in the container is not leaked, thereby preventing contamination of the developing device and the operator's hand.
在显影剂容纳部分 2的端面上设有旋转方向的指示, "on"代表显影剂排 放口 3打开方向, "off"代表显影剂排放口 3关闭方向。安装拆卸时,操作者 可按指示方向旋转抓握部分 4b。 An indication of the direction of rotation is provided on the end face of the developer accommodating portion 2, "on" represents the opening direction of the developer discharge port 3, and "off" represents the closing direction of the developer discharge port 3. When installing and disassembling, the operator can rotate the grip portion 4b in the direction indicated.
在显影剂供应容器内有一滑块 9, 滑块 9有一幵口 (未示出)。 显影剂供 应容器安装到成像装置时, 活门构件 4的活门部分 4a插入到滑块 9中, 从而 使滑块 9与活门构件 4相互联系的移动,可实现显影剂供应容器 1的排放口 3、 显影装置侧的滑块 9的开口及显影剂接纳部分的开口(未示出)同时打开、关 闭。 There is a slider 9 in the developer supply container, and the slider 9 has a mouthpiece (not shown). When the developer supply container is mounted to the image forming apparatus, the shutter portion 4a of the shutter member 4 is inserted into the slider 9, so that the movement of the slider 9 and the shutter member 4 in association with each other can realize the discharge port 3 of the developer supply container 1, The opening of the slider 9 on the developing device side and the opening (not shown) of the developer receiving portion are simultaneously opened and closed.
基于本发明构思的变化并不仅限于上述实施例,还可有多种变化,还可以 将上述实施例中的结构进行有针对性的取舍,组合出新的实施方案,这些简单 的结构变化仍属本发明要求的保护范围。
工业应用性 Variations based on the inventive concept are not limited to the above embodiments, and various changes are possible. The structures in the above embodiments can also be selectively selected and combined with new implementations. These simple structural changes are still The scope of protection required by the present invention. Industrial applicability
依据本发明的显影剂供应容器不但打开 /关闭活门机构的操作更为容易、 准确, 而且结构更为简单, 装配步骤少, 制造成本低, 并能保证在储运过程中 活门机构不会自行打开, 造成显影剂泄漏。
The developer supply container according to the present invention not only opens and closes the shutter mechanism more easily and accurately, but also has a simpler structure, fewer assembly steps, lower manufacturing cost, and ensures that the shutter mechanism does not open itself during storage and transportation. , causing the developer to leak.
