    • It is intended to provide a tape printer which enables to forcibly separate a platen roller and a print head along with an opening movement of a cover element in case the platen roller and the print head have adhered to each other because of a long-period storage of the tape printer with the platen roller and the print head being in contact. Accordingly, a cam pressing member and a cam receiver move a roller holder to a withdrawing position in which the platen roller and a thermal head are separated from each other when the cover element is opened, so that the cam pressing member and the cam receiver can be forcibly returned to the withdrawing position from a position in which the platen roller is in contact with the thermal head.
    • 旨在提供一种带式打印机,其能够在压纸辊和打印头彼此粘附的情况下强制地分离压纸辊和打印头以及盖元件的打开运动,因为长时间存储 的带式打印机与压纸辊和打印头接触。 因此,当盖元件打开时,凸轮按压构件和凸轮接收器将辊保持器移动到其中压纸辊和热敏头彼此分离的抽出位置,使得凸轮按压构件和凸轮接收器可以 被强制地从压辊与热敏头接触的位置返回到退出位置。

    • An electronic component feeder is provided for feeding electronic components in their stable position into an electronic component mounting apparatus and allowing the taking up of a top tape with high stability thus increasing the speed of component mounting action. As the top tape (4) is being taken up on a reel (42), a shutter (34) moves backward together with a slit (51) provided integral on the shutter (34). The turning in the tape take-up direction of the reel (42) is driven by the restoring force of a return spring (39). When the reel (42) has completed its take-up motion, the electronic component (1) can be picked up at a component pick-up location with the shutter (34) staying backward. A stationary roller (31) is provided between the slit (51) and the reel (42) and a movable roller (32) is provided for keeping the length of the top tape (4) between the slit (51) and the stationary roller (31) substantially constant.

    • Disclosed is a method for producing an acetal copolymer, which comprises copolymerizing trioxane with a cyclic ether in the presence of a cation-active catalyst, wherein the cyclic ether is obtained by adding to a fresh cyclic ether containing a peroxide derived therefrom in an amount of 15 ppm by weight or less in terms of hydrogen peroxide at least one sterically hindered phenol in an amount of from 10 to 500 ppm by weight, based on the weight of said fresh cyclic ether. By the method of the present invention, it has become possible not only to stably and efficiently produce an acetal copolymer having high thermal stability, but also to stably conduct a post-treatment of the obtained acetal copolymer for deactivating the remaining catalyst and changing the unstable terminals to stable terminals, so that an ultimate acetal copolymer having high thermal stability can be stably obtained.
