PURPOSE:To make it possible to automatically hold an attaching rod at the tripping position when moving a carriage and to prohibit the operation of the attaching rod when the movement of carriage is not required by forming an out-position attaching portion and in-position attaching portion to an attaching bracket mounted to the front of a drawer type auxiliary machine carriage. CONSTITUTION:When a base 19 of an attaching rod 18 is positioned at an out-position attaching part 12 of a long hole 11, a tip portion 20 of the attaching rod 18 is inserted to a connecting hole of disconnecting hole 5 of a positioning bracket 3, so that pull-out and storing operation for a drawer type auxiliary machine carriage 6 cannot be done and the carriage 6 is fixed. Next, when moving the carriage 6, the base 19 of the attaching rod 18 is moved to the right along the long hole 11, and the base 19 is moved to in-position attaching portion 24. At this time, a tripping state of the attaching rod 18, that is, the state of separating from the positioning bracket 3 is maintained. When the carriage 6 is not required to be moved, a clear cover 25 is mounted to the front of the carriage 6 by a pin 26, this covers the attaching bracket 9 and the base 19 attaching rod 18 thereby prohibiting the operation of the attaching rod 18. |
