SOUND RECORDING/REPRODUCING DEVICE IN COMBINATION WITH MODIFIED TAPE CASSETTE, SOUND RECORDER/REPRODUCER AND RECORDER CAPABLE OF USING APPROPRIATELY SINGLE-FACE SOUND RECORDING AND DOUBLE-FACE SOUND RECORDING AND ALSO USING CONVENTIONAL RECTANGULAR TAPE CASSETTE

摘要

PURPOSE:To simplify a structure, to eliminate a trouble, to lighten the weight, to scale down a device and to improve the portable handiness by combining the tape cassette whose one end is of a circular part and whose front and rear can be identified at a glance, a sound recorder having a spring projection and a reproducer. CONSTITUTION:One end of a cassette is made a circular part 2. A sound recorder and reproducer are separately provided, and projections of spring type 3 are provided on both of them. Thus when a modified cassette having the circular part 2 is mounted on the sound recorder and reproducer having the projections 3, it can be operated at a glance without mistaking four sides. When the sound recorder and reproducer are separated by an easy operation without an error,one is used for sound recording and the other is used for reproducing, and moreover both devices are simultaneously used to copy the sound recording. Both devices are simplified in terms of structure, thereby eliminating a trouble. Furthermore they are weight-lightened and scaled down, and are convenient to carry them.
