    Abstract: PURPOSE:To enagle a spring to be easily attached through simple constitution, by a method wherein a hook part is pressed in all the way through to a hook part by means of a projecting member. CONSTITUTION:A spring hooking structure is formed with a coil spring 9, having a hook part 10 wound one time or more, and a spring mounting member 8, having engaging parts 11a and 11b, by means of which the hook part 10 is engaged. A head part 12, having brim parts 12a and 12b for preventing pull-off, which are spread further toward both ends in the direction of the diameter of the hook part 10 than the engaging parts 11a and 11b, is attached to a spring mounting member 8. This constitution, since the height of the mounting member has no relation with an effect of preventing unhooking of the soil spring, enables decreasing of height.

    Abstract: PURPOSE:To obtain a tape cassette interchangeable with a floppy disk and rapidly increasing a recording capacity by rocking a bevel gear pivoted to an ascillating plate when a center core normally or reversely rotates a transfer mechanism. CONSTITUTION:One end of an oscillating plate 5 having the other end idly fitted into a shaft P1 is connected to an oscillating gear 4 through a clutch mechanism consisting of a slip board 4A and a spring coil 4B. Such transfer mechanism controls so as to oscillate the oscillating plate 5 sideways according to a rotating direction of a pulley 3 as indicated in a normal and reverse rotation mechanism of a tape recorder and engage the oscillating gear 4 with adjacent gears (bevel gears) 6a or 6b. Thereby, a structure interchangeable with a floppy disk can be obtained. Since a magnetic tape can be used, a recording capacity can be rapidly increased.

    Abstract: PURPOSE:To agree a cartridge surface with a recording tape surface as well as a floppy disk cassette and to execute the recording and reproducing with the recording reproducing device of a floppy disk by providing a guide mechanism to incline a tape surface by 90 deg. at the tape travelling path of a head driving type cassette tape. CONSTITUTION:At the position corresponding to the rotation center of the floppy disk of a half 9 at the lower side of a tape cartridge 10, a center core 1 is rotatably fitted and a shaft hole 1A in which the shaft of a spindle motor rushes into the center of the core 1 and a driving hole 1B in which the driving pin of the chucking table of the motor rushes are provided. Between the core 1 and a pulley 3, a timing belt 2 is spread, and between the pulley 3 and reels 6a and 6b, a magnetic tape 7 is spread. In the travelling path of the tape 7, the mechanism to incline, by 90 deg., the surface of the tape 7 by guide pins 8a1 and 8a2 and inclining guides 8b1 and 8b2 is provided. The tape surface and the core 1 are coincident with a floppy disk and the recording and reproducing are executed by the recording and reproducing device of the floppy disk.
