As described above, the memory 110 in the cassette
Is constructed without a battery, so that the cassette side antenna 12
0 and the device-side antenna 190 need to have enough electromagnetic coupling to cover data transmission and power transmission. For this reason, a structure in which the magnetic path is cut off or limited by metal secures the communication distance. It is undesirable in doing. By the way, in the recording / reproducing device 130, the device-side antenna 190 is connected to the opening 153 of the front plate 153 of the slide chassis 150.
a, the device-side antenna 190 and the cassette-side antenna 1
20, sufficient electromagnetic coupling can be ensured.

The front plate 1 of the slide chassis 150
Since the openings 153a of the 53 do not interrupt the magnetic path, if there is a problem such as a decrease in strength due to the formation of the openings, the openings 153a are non-magnetic and non-conductive and transmit radio waves. It may be covered with a material to be made, for example, a plastic plate or the like.

When the decorative plate 154 is formed of a material such as a metal plate that is magnetic and conductive and does not transmit radio waves, an opening may be provided at a position corresponding to the device-side antenna 190. The magnetic path can be prevented from being interrupted.

Next, the recording / reproducing operation using the tape cassette 10 will be described.

The tape cassette 10 is inserted into the cassette holder 170 with the moving frame 160 pivoting upward and the cassette holder 170 at the eject position shown in FIG. 5 (see FIGS. 11 and 12). Tape cassette 10
By inserting the tape cassette 10 into the cassette holder 170, the tape cassette 10
2, 173 and the receiving plates 174, 174, the front lid 60 is unlocked by the lid lock member 90, the front lid 60 rotates upward, and the front lid 60 and the slider 80 are rotated. (Along with the back lid 70) is moved backward,
The portion of the magnetic tape 30 located in front of the mouse 21 is opened, and the upper part of the mouse 21 is opened.

Then, when the moving frame 160 is rotated downward, the cassette holder 170 is also lowered accordingly, and when the cassette holder 170 is lowered to the lowermost holding position of the lowering range (see FIG. 13), The reel bases 155 and 155 provided on the slide chassis 150 are inserted into the cassette shell 20 from the reel base insertion holes 22 and 22, and the reel engaging shafts 155 of the reel bases 155 and 155 are provided.
a, 155a engage with the reel base engaging holes 40a, 50a of the tape reels 40, 50. Also, the main chassis 1
The tape pull-out guides 142, 142, a pinch roller (not shown), and the like provided on the mouse 40 are located in the mouse 21.

In the state shown in FIG. 13, the outer surface of the cassette-side antenna 120 of the tape cassette 10 faces the inner surface of the device-side antenna 190 provided on the front plate 153 of the slide chassis 150. The communication between the device and the in-cassette memory 110 of the tape cassette 10 becomes possible. Therefore, the recording / reproducing device 13
At 0, the slide chassis 150 is pulled into the main chassis 140 (see FIG. 7), and the contents of the memory 110 in the cassette are read before the tape cassette 10 is ready for recording or reproduction. Information can be written to the memory 110 in the cassette. In the state where the slide chassis 150 is in the cassette delivery position pulled out from the main chassis 140, the front plate 153 is in a state close to the front of the outer casing, that is, the device-side antenna 190 is in a state close to the front of the outer casing. The front face of the outer casing is non-magnetic and non-conductive, and even in such a case, the portion facing the device-side antenna 190 is provided as a radio wave transmitting section, so that the tape cassette 10 can be recorded and reproduced. Even if the cassette-side antenna 12 is not attached to the apparatus,
If 0 is opposed to the device-side antenna 190 via the front surface of the outer casing, the communication circuit 200 can be driven to communicate with the in-cassette memory 110 of the tape cassette 10. Therefore, the tape cassette 10 is transferred to the recording / reproducing device 13.
Before the tape cassette 10 is mounted on the tape cassette 10, the recorded contents of the tape cassette 10 can be known.

Next, the slide chassis 150 moves backward with respect to the main chassis 140, and reaches a predetermined retracted position, that is, a recording / reproducing position.

When the slide chassis 150 reaches the recording / reproducing position, the tape pull-out guides 142, 142
The magnetic tape 30 is pulled out of the cassette shell 20 by moving a magnetic tape 30 to a predetermined position, and the magnetic tape 30 is wound around the rotary head drum 141 at a predetermined winding angle and a predetermined tape path is formed.

When the recording or reproduction on the magnetic tape 30 is completed, the members such as the tape pull-out guides 142 and 142 and the pinch roller move into the mouse section 21, and the extra magnetic tape 30 is wound on one tape reel 40. .

Then, the slide chassis 150 is returned to the cassette delivery position, and
0 rotates upward, and the cassette holder 170 is located at the eject position. Then, the tape cassette 10 is pulled out from the cassette holder 170.

In the recording / reproducing apparatus 130 described above,
Since the opening 153a is formed in the metal portion corresponding to the portion where the device-side antenna 190 is located, sufficient electromagnetic coupling is obtained between the device-side antenna 190 and the cassette-side antenna 120, and Communication with the device-side antenna 190 is performed efficiently. Thereby, the slide chassis 1 serving as the cassette holding member
Since the 50 can be formed using a metal, the size of the recording / reproducing device 130 can be reduced.

It should be noted that the shapes and structures of the respective parts shown in the above-described embodiments are merely examples of the embodiment to be carried out when carrying out the present invention, and the technical scope of the present invention is not limited thereto. Should not be interpreted restrictively.
