<p><P>PROBLEM TO BE SOLVED: To prevent a tray drawn out up to a work position from being pushed inward, in a line-terminated tray unit wherein when a tray 18 is drawn out up to a work position from a stored position, a forward step position 34 formed on the upper edge of both side frames of the tray is abutted to an up-and-down movable stopper 20, so that the tray 18 cannot be drawn out any more. <P>SOLUTION: A backward step part 40 is formed on the upper edge of both side frames of the tray 18 so as to be faced to the forward step part 34, and also a slope 42 gradually lowering in height toward the front end of the tray 18 from the top part of the backward step part 40 is formed. When the tray 18 is dawn out up to the work position, a stop piece 26 of the stopper 20 drops between the forward step part 34 and the backward step part 40, then the tray 18 cannot be drawn out, nor can it be pushed inward. <P>COPYRIGHT: (C)2004,JPO</p> |
