Filed: 1986-06-17
Abstract: PURPOSE:To assemble a panel and a mask of a cathode-ray tube reliably by giving driving force in a vertical direction from the downside to a locating pin engaged with a frame in a state of pressing the frame downward with a pressing lever. CONSTITUTION:A holder H for a frame F of a mask M is released by retraction of a pushing pin 26, and this holder is moved to a pin PP of an outer panel P by its own spring property. Then driving force in the vertical direction is given to a locating pin 12 engaged with the frame F from the downside in a state of pressing the frame F downward by a pressing lever 16. Therefore, if a hole hh of the holder H and the pin PP are not fitted right in each other, the hole hh moves up and down to the pin PP, whereby the hole hh and the pin PP are fitted right in each other. Especially at this time, upward motion is accurately performed by the locating pin 12, while downward motion is accurately performed by the pressing lever 16 as well. Accordingly, the fitting between the hole hh and the pin PP is accurately performed, thus the panel P and a mask M of a picture tube can be reliably assembled together.
