Patent JP-H09123687-A (JP)
Title: Drafting machine
Inventor: OGAWARA SHINJI
IPC: B43L13/04
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To avoid collision of a handle part and a scale with a drawing board by a construction wherein a decelerating means for decelerating a downward rotating motion of the handle part by giving a large resistance when the handle part is rotated downward toward the drawing board is incorporated in an axially fitting part between the handle part and a link part. SOLUTION: When a handle part is rotated upward so that it separates from a drawing board, a long axis is rotated in the direction of an arrow B. At this time, air in a space between the axis and a projecting piece 54 moves easily to a space on the opposite side through an opening part 48 having a large opening area and a reed valve 50 and, therefore, the handle part can be rotated lightly. At the time when the handle part is rotated downward toward the drawing board side, that is, when the long axis is rotated reversely to the direction B, on the other hand, the air in the space moves to the space on the opposite side through a passage 56 having a small opening area and, therefore, the rotating motion of the handle part is decelerated.
