<p><P>PROBLEM TO BE SOLVED: To provide a means for retaining an inclined posture by varying it stepwise while maintaining a touch of rigidity, even when an input unit having a relatively large weight is attached to a support unit having a tilt mechanism. <P>SOLUTION: On a support unit 3 having the tilt mechanism for supporting a tilt plate 5, having an attachment portion 7 for attaching an input unit 1, in a rotatable manner via a hinge 8 disposed on the end portion of a base plate 4, there are provided a front plate 10 and a rear plate 11, and a side plate 12 each bent into an L shape, respectively on the front end portion, the rear end portion and both sides of the side edge portion of the tilt plate 5. By the bending of the tip end portion of the side plates 12, a U-shaped bending portion 13 is formed. Further, on the side plate 12, a plurality of leading grooves 22 are formed, and also, between the end plane of mouths 23 thereof and a guide plane 13a of the U-shaped bending portion 13, a moving groove 26 is formed. By the intermediary of an arm 18, a locking bar 14 is supported in a rotatable manner around a fulcrum shaft 15 disposed on the base plate 4, and is energized by a torsion spring 28 to the direction of the front end portion of the tilt plate 5. By the latch of the locking bar 14 on the leading grooves 22, the inclined posture of the tilt plate 5 is made to vary stepwise. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
