    • A rotating polygon mirror deflects a continuous laser beam, applying the deflected beam to a beam-splitting mirror through a focusing lens 6 which functions as an f.theta. lens. The beam is applied to the two reflective surfaces of the mirror alternately. As a result, the mirror splits the beam into two beams, which are applied to two beam-splitting mirrors, respectively. The mirrors split the input beams, each into two segment beams. The four segment beams are focused by four lenses onto the surface of a web sheet, thereby forming beam spots. The beam spots move in the same direction and at the same speed as the web sheet, thus scanning limited surface regions of the sheet. As a result, rows of perforations, each being a truly circular hole, are formed in the web sheet.
    • 旋转多面镜偏转连续的激光束,通过用作fθ透镜的聚焦透镜6将偏转的光束施加到分束镜。 光束交替地施加到镜子的两个反射表面。 结果,镜将光束分成两束,分别施加到两个光束分离镜。 镜子将输入光束分成两束。 四个分段光束由四个透镜聚焦到幅片表面上,从而形成光束点。 光束斑与纸幅相同的方向和速度移动,从而扫描片的有限表面区域。 结果,在幅材片材中形成有穿孔的排,每个孔都是真正的圆形孔。

    • A belt-like material stably transferring apparatus an absorbing and feeding apparatus for continuously absorbing and feeding the belt-like material by use of a difference in air pressure. The absorbing and feeding apparatus comprises a reserving chamber for absorbing and feeding the belt-like material to be reserved therein, and a pressure detecting chamber connected to the reserving chamber through a slit. The reserving chamber has an opening portion for feeding the belt-like material, and blowers and are connected at a position, which is opposite to the opening portion. The pressure of the pressure detecting chamber is changed in accordance with the change of the pressure in the reserving chamber connected to the pressure detecting chamber through the slit. The pressure of the reserving chamber is changed in accordance with the amount of absorbing and feeding the belt-like material absorbed and fed to the reserving chamber. Due to this, the pressure of the pressure detecting chamber is detected by pressure detectors, thereby the amount of absorbing and feeding the belt-like material absorbed and fed to the reserving chamber is detected. The belt-like material stably transferring apparatus comprise analog cards for controlling the amount of supplying the belt-like material based on the amount of absorbed and fed belt-like material.
    • 带状材料稳定地传送装置,用于通过使用空气压力的差异来连续吸收和馈送带状材料的吸收和供给装置。 吸收和输送装置包括用于吸收和供给要保留的带状材料的储存室,以及通过狭缝连接到储存室的压力检测室。 储存室具有用于输送带状材料的开口部分和鼓风机,并且在与开口部分相对的位置处连接。 压力检测室的压力根据通过狭缝连接到压力检测室的储存室中的压力变化而改变。 储存室的压力根据吸收并供给到储存室的带状材料的吸收和进给量而改变。 由此,通过压力检测器检测压力检测室的压力,从而检测吸收并供给到储存室的带状材料的吸收和供给量。 带状材料稳定转印装置包括用于基于吸收和输送的带状材料的量来控制供给带状材料的量的模拟卡。
