    • PROBLEM TO BE SOLVED: To reliably close a powder discharge port provided in a powder container body by means of a shutter by moving the powder container body to a position farther than the moving distance of a shutter member that opens and closes the powder discharge port. SOLUTION: The powder supplying device includes: a powder container 32 which is provided with the powder container body 33Y and the shutter member 35, wherein the powder container body is detachably installable in the powder container containing part horizontally and is provided with the discharge port B through which inside powder is discharged outside, and wherein the shutter member opens and closes the discharge port by moving along the container body in a direction in which the powder container is removed; and a shutter regulating member 82 provided at the side of the powder container containing part, wherein the shutter regulating member turns in conjunction with the removal operations of the powder container to thereby allows the shutter member to perform open and close actions. When the powder container body is pulled out, the shutter regulating member revolves in conjunction with the pull-out, the shutter member is thereby closed. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:通过将容器主体移动到比打开和关闭粉末的活门构件的移动距离更远的位置,通过活门可靠地关闭设置在粉末容器主体中的粉末排出口 排气口。 解决方案:粉末供应装置包括:粉末容器32,其设置有粉末容器主体33Y和活门部件35,其中粉末容器主体可水平地可拆卸地安装在粉末容器容纳部分中,并且设置有 排出口B通过内部粉末排出到外部,并且其中活门构件通过沿着容器主体沿粉末容器被移除的方向移动而打开和关闭排出口; 以及设置在粉末容器容纳部分侧面的快门限制部件82,其中快门限制部件与粉末容器的移除操作一起转动,从而允许快门部件执行打开和关闭动作。 当粉末容器主体被拉出时,快门限制部件与拉出一起旋转,因此挡板部件被关闭。 版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To prevent mixing with foreign matters. SOLUTION: The powder storage container includes: a powder storage container body that stores powder and has a powder supply port for supplying the powder; and a shutter 42 having a shutter member that is disposed so as to freely rotate with respect to the powder storage body and opens or closes the powder supply port according to the rotation. The shutter 42 has a restricting element for restricting rotation of the shutter member when the powder supply port faces upward. Since the rotation of the shutter member is restricted when the powder supply port faces upward, this prevents powder supply port from being opened accidentally. Accordingly, mixing with foreign matters such as paper powder, in the powder storage container can be prevented. COPYRIGHT: (C)2010,JPO&INPIT
    • 要解决的问题:防止与异物混合。 解决方案:粉末存储容器包括:粉末存储容器体,其存储粉末并具有用于供应粉末的粉末供给口; 以及具有挡板部件的挡板42,闸板部件被设置为相对于粉末存储体自由旋转,并根据旋转来打开或关闭粉末供给口。 挡板42具有限制元件,用于当粉末供应口朝上时限制闸门构件的旋转。 由于当粉末供给口朝上时,挡板部件的旋转受到限制,因此防止粉末供给口意外打开。 因此,可以防止与粉末等异物混合在粉末储存容器中。 版权所有(C)2010,JPO&INPIT
