    • A presentation system for a presenter to safely point out parts of an image projected from a projector onto a screen with laser light projected from a laser pointer held by the presenter is disclosed. The presentation system includes one or more infrared light receiving units on the laser pointer that selectively receive infrared signals from sending units that are mounted on the projector or on walls in order to control emission of laser light from the laser pointer. Arrangements of the sending and receiving units are designed to allow emission of the laser light from the pointer only when the laser pointer is pointed toward the projection screen. A control unit in the laser pointer may determine if the laser pointer is pointed correctly or a gravity operated shutter may further assist in preventing unsafe projection of laser light from the laser pointer.
    • 本发明公开了一种演示系统,用于通过从由演示者所保持的激光指示器投影的激光将安全地将从投影仪投影的图像的一部分指向屏幕上。 呈现系统包括在激光指示器上的一个或多个红外光接收单元,其选择性地接收来自安装在投影仪或壁上的发送单元的红外信号,以便控制来自激光指示器的激光的发射。 发送和接收单元的布置被设计成仅当激光指示器指向投影屏幕时才能从指针发射激光。 激光指示器中的控制单元可以确定激光指针是否正确指向,或者重力操作的快门可进一步有助于防止来自激光指示器的激光的不安全投影。

    • A toner replenishing device for an image forming machine has a hopper housing with a toner agitating passageway and a toner carrying passageway, a toner agitator disposed in the toner agitating passageway for agitating recovered toner and fresh toner supplied to the toner agitating passageway and lifting them to the toner carrying passageway, and a toner carrier disposed in the toner carrying passageway for carrying the recovered toner and the fresh toner agitated and lifted by the toner agitator. The toner agitator has a first paddle disposed in a first end part of the toner agitating passageway, and a second paddle disposed on the other end part side of the toner agitating passageway and adjacent to the first paddle. The first paddle has the function of sending the toner to the other end part side of the toner agitating passageway, while the second paddle has the function of sending the toner to the first end part side of the toner agitating passageway.
