    • An electronic camera has an image pickup section and a detachable recording section. The image pickup section includes an image pickup element for converting an optical image into an analog image signal. The image pickup section also includes an analog-to-digital converter for converting the analog image signal into digital image signals which are stored in a digital memory within the image pickup section. The detachable recording section includes a digital-to-analog converter for converting the digital signal output from the image pickup section into an analog signal which is recorded in an analog memory within the recording section.

    • A zoom lens comprising four lens groups, the first group for focusing control having a positive focal length, the second group as a variator having a negative focal length, and the third group as a compensator having a positive focal length. The rays emanating from the third group are substantially parallel with respect to a common axis of the lens groups including the fourth lens group which serves as an image-forming lens and which has a positive focal length. The first group has a positive lens of a negative meniscus lens and a bi-convex lens cemented together and a positive meniscus lens, the second group has a negative meniscus lens and a negative lens comprising a bi-concave lens and a positive lens cemented together, and the third group has a negative meniscus lens and a bi-convex lens. The fourth group is composed of a positive meniscus lens, a bi-concave lens, two bi-convex lenses and a negative meniscus lens.

    • An impact line printer is provided with a character drum which has characters such as letters and numerals on the peripheral surface thereof and printing hammers in opposite to the character drum, wherein a printing paper is passed between the character drum and the printing hammers. The printer is further provided with a driven shaft on which is mounted frictional discs. Wheel members are provided, each of which is opposed to and normally spaced apart from each of the frictional discs. The wheel members are selectively brought into contact with the frictional discs to actuate selected printing hammers to effect printing on the printing paper. The printing hammers on normally biased for example by means of spring to keep away from the character drum.
    • 冲击线打印机设置有字符鼓,其字符和数字在其外围表面上具有字符和数字,并且打印锤与字符鼓相对,其中打印纸在字符鼓和打印锤之间通过。 打印机还设置有从动轴,摩擦盘安装在从动轴上。 设置有轮构件,每个轮构件与每个摩擦盘相对并且通常间隔开。 轮构件选择性地与摩擦盘接触以致动所选择的打印锤以在打印纸上进行打印。 打印锤通常通过例如通过弹簧偏压以远离字符鼓。
