    • A torque wrench equipped with a cam-type torque detection mechanism is provided which is capable of detecting a torque with high accuracy, providing a non-unusual-feeling of handle operation after torque has been detected, and enabling tightening of fastened members such as bolts with safety. In a torque wrench equipped with the cam-type torque detection mechanism, a cam portion 27 formed on the outer circumference of a tubular cam 22 includes: a static engagement cam surface 27a with which a roller member 18 in a static status engages in a non-operated status; a gradually increasing torque peak cam surface 27b which is connected to the static engagement cam surface 27a and with which the roller member 18 is brought into contact while moving to thereby gradually increase the torque peak value; a cam top surface 27c forming the cam top portion continued to the gradually increasing torque peak cam surface 27b; a gradually decreasing torque cam surface 27d for gradually decreasing a plus torque to the roller member 18 to zero; and a minus torque cam surface 27e for imparting a minus torque to the roller member 18 having passed over the gradually decreasing torque cam surface 27d.
    • 本发明提供一种具有凸轮式转矩检测机构的扭矩扳手,其能够高精度地检测转矩,在检测到扭矩后提供非异常手感操作,并且能够紧固诸如螺栓的紧固构件 安全。 在装配有凸轮式转矩检测机构的扭矩扳手中,形成在管状凸轮22的外周上的凸轮部分27包括:静态接合凸轮表面27a,静态状态的辊构件18通过该静态接合凸轮表面27a 操作状态; 逐渐增加的扭矩峰值凸轮表面27b,其连接到静态接合凸轮表面27a,并且使滚子构件18在移动时接触,从而逐渐增加扭矩峰值; 形成凸轮顶部的凸轮顶面27c与逐渐增加的转矩峰值凸轮表面27b相连; 逐渐减小的转矩凸轮表面27d,用于逐渐减小到辊构件18的加力到零; 以及负转矩凸轮面27e,用于向经过逐渐减小的转矩凸轮面27d的辊部件18赋予负转矩。

    • Provides an automatic changer with excellent space efficiency, by reducing the size of a hand mechanism section that is mounted with a CCD. The automatic changer selects and holds one desired cartridge from among one of accommodation cells provided in a magazine, conveys this selected cartridge to a recording/reproducing apparatus, and reads a bar code label adhered to the side surface of the cartridge thereby to identify the cartridge. The automatic changer has the CCD that reads a bar code disposed in the inner part of a casing that movably accommodates a hand mechanism section for holding the cartridge. The automatic changer also has a condenser lens for focusing the image of the bar code on the CCD disposed at one part of the hand mechanism section. With this arrangement, the automatic changer moves the hand mechanism section to the front of the cartridge accommodated in the accommodation cell, and focuses the image of the bar code on the CCD. Then, the CCD identifies the contents of the cartridge.
    • 通过减小安装有CCD的手动机构部分的尺寸,提供优异的空间效率的自动更换器。 自动更换器从设置在盒中的容纳单元之一中选择并保持一个期望的盒,将该选择的盒传送到记录/再现装置,并读取附着在盒的侧表面上的条形码标签,从而识别盒 。 自动更换器具有CCD,其读取设置在壳体内部的条形码,该条形码可移动地容纳用于保持盒的手机构部分。 自动变换器还具有用于将条形码图像聚焦在设置在手动机构部分的一部分的CCD上的聚光透镜。 通过这种方式,自动更换器将手机构部分移动到容纳在容纳单元中的盒的前部,并将条形码的图像聚焦在CCD上。 然后,CCD识别墨盒的内容。
