穿孔装置

Abstract

提供一种能减少操作杆的旋转移动量、同时可减轻操作力的穿孔装置。穿孔装置(10)的构成包括:配置在具有纸(P)的支撑面(11)的基座(12)上的一对侧部部件(14、15);可以设置在这些侧部部件(14、15)之间的旋转轴(16)为旋转中心转动的操作杆(18);由可升降地设置在侧部部件之间的滑动部件(20)支撑的穿孔刀具(24);以及将上述操作杆(18)与该滑动部件(20)可相对旋转地连结的连杆部件(21)。连杆部件(21)做成圆弧状的片状,相对其中心设置为对称形状,并且将连杆部件(21)和滑动部件(20)的连结位置(A2)设置成使其位于与穿孔刀具(24)大致同一轴线的位置。
The invention provides a puncher capable of reducing rotation amount as well as operation force for a operation level. The puncher 10 includes a pair of side members 14, 15 disposed on a base 12 having a support surface 11 for sheets P, an operation lever 18 rotatable around a rotation shaft 16 provided between the side members 14, 15, punch blades 24 supported by a slide member 20 provided movable vertically between the side members, and link members 21 each connecting the operation lever 18 and slide member 20 relatively rotatably. Each of the link members 21 is provided in an arc piece shape being symmetrical with respect to a center thereof, and a connecting position A2 between the link member 21 and the slide member 20 is located substantially on the same axis line as that of the punch blades 24.
