| 摘要 |
The present invention concerns a device that can be used to easily and randomly draw a plurality of numbers one after the other from a large quantity of differently marked balls contained in a first chamber by a repeated manual activation of a horizontal movable bar that randomly captures one marked ball at a time from a first upper chamber into a cavity in the movable bar and transfers it to an elongated second lower chamber to display the captured and drawn marked balls. The second chamber includes two adjacent elongated channels and a channel selection member that includes a door rotatably mounted onto the device to leave only one of the channels opened and accessible for the captured balls at a time.
