    • PROBLEM TO BE SOLVED: To prevent positional slippage of a printed circuit board placed on a movable table and the movable table at the time of moving the movable table of a standard hole drilling machine. SOLUTION: The printed circuit board (not illustrated) which is a work is placed on the movable table 12 of the standard hole drilling machine 1. The work is sucked and fixed by air of negative pressure applied on pores (not illustrated) opened in a large number on the movable table 12. An axis of rotation is provided at right angles with the moving direction of the movable table on a central part of a printed circuit board presser 71, a presser roller 72 to rotate in accordance with movement of the movable of table 12 is set, and this presser roller 72 is singly free to move vertically. When the work is inserted at a working position, the printed circuit board presser 71 and the presser roller 72 are lowered at a working starting position, the printed circuit board presser 71 pressurizes the work when the movable table stops, pressurizes the work on the movable table 12 until working is finished, and it prevents positional slippage.

    • PROBLEM TO BE SOLVED: To realize an inexpensive perforating device. SOLUTION: The paper 10 on which perforation is to be formed is transported at high speed in a tense state by means of rollers 12, 14. A carbon dioxide gas laser 16 generates a laser beam continuously. A shutter disk 18 equipped with a number of fins (8 fins in this embodiment) radially is placed at a position shifted horizontally from the optical path of the laser 19 output beam, and rotated at a prescribed revolution speed by a motor 20. The output beam of the laser 16 is intermittently shielded with the fins of the shutter disk 18. The motor 20 is fixed on a holding plate 22 movable against a fixed part. With the holding plate 22, the shutter disk 18 can be adjusted in the horizontal shift quantity against the output beam of the laser 16. The horizontal shift quantity determines the cut/tie ratio of perforation.
    • 要解决的问题:实现廉价的穿孔装置。 解决方案:要在其上形成穿孔的纸张10通过辊12,14以高速传送。二氧化碳气体激光器16连续地产生激光束。 放置有多个翅片(本实施例中为8个散热片)的快门盘18放置在从激光器19输出光束的光路水平偏移的位置,并通过马达20以规定的转速旋转。输出 激光器16的光束与快门盘18的翅片间歇地屏蔽。马达20固定在可抵靠固定部分移动的保持板22上。 利用保持板22,快门盘18能够相对于激光器16的输出光束以水平移位量进行调节。水平移动量决定了穿孔的切割/拉伸比。

    • PURPOSE:To improve the work efficiency with a simple construction by conducting a laser beam from semiconductor laser elements arranged in lines to a paper conveying route via a cellphox lens eye for cutting a roll paper. CONSTITUTION:A roll paper 14 from a holder 7 is conveyed to a copying point of a photosensitive body 9 through a feed-roller pair 8. When a paper top detector detects the top of the paper, the signal is sent to semiconductor laser elements 10... arranged in lines on substrates for outputting a laser beam. This beam is linearly condensed at a proper position on a paper conveying route below via cellphox lens eye 9 and 9 to be intensified, and simultaneously radiated in the width of the roll paper 14 for cutting the roll paper by the energy of radiation. This construction permits to cut papers efficiently with a simple construction without using a polyhedral mirror and reduce the frequency of troubles.
    • 目的:通过将半导体激光元件的激光束经由用于切割卷纸的细胞晶状体眼线的纸张输送路线排列成线状的激光元件,通过简单的结构来提高工作效率。 构成:来自保持器7的卷纸14通过进给辊对8被传送到感光体9的复印点。当纸顶检测器检测到纸张的顶部时,信号被发送到半导体激光元件10 ...排列成用于输出激光束的基板上的线。 该光束在通过细胞晶状体眼9和9的下方的纸张传送路径上的适当位置处被线性聚焦,以被加强,同时以卷纸14的宽度辐射,以通过辐射能量切割卷纸。 这种结构允许以简单的结构有效地切割纸张,而不使用多面体镜子并减少故障频率。
