Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a T-dubter for playing micro cassette tapes on a compact cassette tape player.

Different types of tapes with different cassette shapes? , J, P type player, if the cassette shape of the tape to be played is smaller than the cassette shape compatible with the player, the size of the small cassette in one compatible cassette will be reduced. At the same time, the tape transport force on the player side is reached to drive the tape of the small cassette, and the adapter that transmits the tape recording signal to the player side via the transducer is installed. It is used by configuring it in the shape of a cassette compatible with a player.

As an example of this adapter, one for playing compact cassette tapes on an all-eight-track cassette player has already been put into practical use.

Incidentally, the cassette shapes of magnetic tapes currently on the market include the aforementioned eight-track cassette, compact cassette, and microcassette. Microcassettes are ultra-compact and can record for relatively long periods of time, so they are very useful as small-sized recording and playback devices, and are often used for recording meetings and other purposes as a substitute for memo writing. -ru.

On the other hand, among the various types of cassette tapes mentioned above, compact cassette tapes have gained the most attention due to the higher precision and diversification of recording/playback equipment and accessories.

Therefore, if you want to record on a micro cassette tape and listen to it simultaneously by a large number of people, such as a trap meeting recording, it would be very helpful if you could use a high-precision Kombaku B Rikishi) I tape player. Therefore, it would be convenient if the above-mentioned playback machine could also be used when playing the personal digital cassette at another location by mail or other means.

The compact cassette-shaped adapter for rounded microcassettes of La, T, and L et al. has not yet been put to practical use. This means that the biggest technical difficulty in providing a practical adapter device is that loading and unloading the compact cassette into the player requires vertical insertion of the tape into the tape winding shaft and the tape unwinding shaft. This is due to the fact that the compact cassette itself is quite bulky, making it difficult to configure the operating mechanism to be assembled into the compact cassette.

The vertical insertion means of the compact cassette is a simple device operation, not a press-fitting operation toward the magnetic head as in the aforementioned eight-track cassette.

This cassette loading operation is expected to bring about a profit or loss that will allow the adapter to produce a unique device.

Moreover, in addition to the compact cassette's small bulk, it requires an insertion hole in the center area for the lead-in shaft and the wind-back shaft. Space is limited - especially to the extent that even the microcassette device field Pfr does not have sufficient installation clearance.

Therefore, in the present invention, the points of et al. are taken into consideration.

First of all, by securing the device location for the micro cassette in the compact cassette half, by configuring the 7th tape run + stage of this micro cassette tape, and the reproduction means for the magnetic recording signal, the compact cassette shape can be improved. Completed a practical version of a playback adapter for micro cassette tapes.

A detailed description will be given below using the illustrated %X-IM example.
