摘要： PROBLEM TO BE SOLVED: To fix a film winding tool in a fitting part with proper pressure. SOLUTION: When a reel 50 is fixed in a film winding tool fitting part, first the reel 50 is externally fitted on a reel shaft 51 and arranged on a reel receiver 53 and second, a fixing device 60A is externally fitted on the reel shaft 51. After that, when a knob member 61 is turned, the male screw 63 of a knob screw member 63 is screwed into the female screw of the top end part of the reel shaft 51 and the reel 50 is held between a pressing member 64 and the reel receiver 53, to be fixed. At this time, the pressing member 64 presses the reel 50 by the energizing force of a compression coil spring 65, so that the reel 50 can be fixed with the proper pressure.

摘要： PURPOSE: To provide a planetary gear mechanism whereby an output of two kinds of reduction ratio can be obtained by a single planetary gear mechanism. CONSTITUTION: A sun gear 32 of constituting a planetary gear mechanism is secured to a rotary shaft 30 of an electric motor 10. Two sheets of pinions 34, 34 are meshed with the periphery of the sun gear 32, to mesh the pinions 34, 34 with the first/second ring gears 39, 37. A lower end of the pinion 34, 34 is pivotally supported by a plate 38, and an upper end is pivotally supported by a carrier gear 36 which is an output gear. Thus by transmitting turning force by rotation of the pinion 34 to the second ring gear 37, an output of the first reduction ratio can be obtained by the second ring gear 37. Since turning force by revolution of the pinion 34 is transmitted to the carrier gear 36, an output of the second reduction ratio can be obtained by the carrier gear 36.

摘要： PURPOSE: To provide a film attaching and detaching method which can relax restriction items of tolerance about a magazine, manufacturing facilities for the magazine, an attaching and detaching instrument for attaching and detaching a beltlike film to and from the magazine. CONSTITUTION: The magazine 10 contains a spool inside rotatably and has an insertion slot through which the beltlike film is put in and out and is equipped with a movable part which exerts a little influence on the movement of the spool and a lock mechanism which locks and unlocks the movable part to and from the magazine 10; and an access opening 34 is formed on the magazine 10 by opening the movable part and then the film attaching and detaching instrument 66 is inserted into the magazine 10 through the access opening 34. While the film attaching and detaching instrument 66 is inserted, the attaching and detaching instrument 66 is used to anchor the beltlike film to the spool or remove it. Then the film attaching and detaching instrument 66 is put out of the magazine 10, the movable part is returned of its original position, and the access opening 34 is closed.
