<P>PROBLEM TO BE SOLVED: To open a device cover in association with obliquely upward hoisting motion of a table unit to expand the table unit without requiring a large force. <P>SOLUTION: The table unit 12 is obliquely hoisted by holding a handle 12a exposed from the device cover 11 of the table unit 12 so that the device cover 11 is obliquely opened in association with the hoisting motion. After the hoisting is finished, the device cover 11 is returned back by spring forces of springs 5, 36. The table unit 12 can take an oblique state in which a table upper 41 and a table lower 42 are folded, and a horizontal state in which the table upper 41 and the table lower 42 can be expanded. <P>COPYRIGHT: (C)2013,JPO&INPIT |
