Document Type and Number:
Japanese Patent JPS649093
Kind Code:
A
Abstract:
PURPOSE:To facilitate the selection of the connection state of a mast by installing an engaging member onto a transfer member and selecting the position for keeping an engaging pin in the engagement state for the engaging member by this engaging member and the position for permitting the engaging pin to be demounted from the engaging member. CONSTITUTION:An engaging member 4 is installed at the lower edge part of a mast 17, and said engaging member 4 is fitted onto a transfer member 5 in demountable ways from above, and an engaging pin 70 held by the transfer member 5 is engaged with the engaging member 4. An engaging member 7 is arranged in the fan-shaped recessed part 52 of the transfer member 5 and installed in rotatable ways around a pin 53. When the engaging member 7 is positioned on one side (shown by full line), a gap is formed between the engaging member 7 and the engaging pin 70. When the engaging member 7 is positioned at the other side (the imaginary line), the top edge of the engaging member 7 contacts the engaging pin 70. Since the engaging member 7 is on a mast rail 2 and is exposed on a board, the operation can be carried out by an operator on the board by using his feet.
