Abstract: PROBLEM TO BE SOLVED: To obtain a tape loading structure without damaging a tape edge by a lead at the time of tape loading and unloading operation on a drum even when the magnetic tape is thin. SOLUTION: The lead R of the rotary drum 13 is arranged at the same height as a height of the lower edge T1 of the magnetic tape T just prior to its loading onto the rotary drum 13. Then, in order to correct unbalance between the upper and lower edges in tension, caused to the magnetic tape T at the time of its loading onto the drum 13, the magnetic tape T is twisted by a tape guide 16 on the outlet side of the drum 13.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of part items of an information detector moving mechanism and to improve the positioning accuracy by moving an information detector along a guide groove formed in a chassis substrate interlocking with a reel base moving mechanism and positioning it. SOLUTION: An information detecting member 50 as an information detector is moved a long a linear guide groove 51 formed in a mechanical chassis 3 associatively with the operation of a reel base moving mechanism. When the information detecting member 50 is moved to a position corresponding to a small tape cassette 4A, its front end part is butted to the groove end part 51a of the guide groove 51, stopped and then positioned. When the information detecting member 50 is moved to a position corresponding to a large tape cassette, its rear end part butts to the stopper 48a of a rack supporting member 48, stopped and then positioned. Thus, the number of part items for the information detector moving mechanism is reduced, an operation is made simple and positioning accuracy is improved.

Abstract: PROBLEM TO BE SOLVED: To provide a reel base positioning mechanism capable of highly accurately positioning a reel base with a simple mechanism by butting a positioning pin coaxial to a reel shaft to the end part of a circular-arc hole formed in a substrate so as to perform positioning. SOLUTION: When a reel base supported by the reel base supporting shaft 28 of a reel base holding member 26 is rotated and moved to the corresponding position of a small tape cassette, a positioning shaft pin 30 butts to one hole end part 31a of a circular-arc hole 31 formed in a mechanical chassis 3 and positioned. When the reel base is rotated and moved to the corresponding position of a large tape cassette, the positioning shaft pin 30 butts to the other hold end part 31b of the circular-arc hole 31 and positioned. Thus, by increasing the accuracy of machining the positioning shaft pin 30 and the hole end parts 31a and 31b of the circular-arc hole 31, a pair of reel bases in which supply side and take-up side tape reels are loaded are accurately positioned in the corresponding positions of the small and large tape cassettes.

Abstract: PURPOSE:To prevent a shaft from slipping out from a base material even if creep is generated, in a pressure-fitting shaft supporting mechanism formed in such a way that a shaft is pressure-fitted in the base material and the shaft is fixed on the base material by pushing and pressing force generated between the base material and the shaft. CONSTITUTION:In the part of a pressure-fitting margin (a), a circumferential groove 1a is provided in a shaft 1. After pressure-fitting, pushing and pressing force is not exerted in the part of a base material opposing to the circumferential groove 1a, a base body 2 is protruded toward the shaft 1 side by a prescribed amount as shown in Figure (d), and it is possible to prevent creep in this part since pushing and pressing force is not generated. It is thus possible to prevent movement of the shaft 1 by this protruded part 2b, and prevent the shaft 1 from slipping out from the base body 2 when fixing force on abutting part between the shaft 1 and the base material 2 is reduced after a lapse of a time, when a soft material such as zinc di-cast and the like is used in the base body 2.
