Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a magnetic recording and reproducing device, and particularly to an improvement that enables selective recording and reproducing of a magnetic card and a cassette tape in one action.

The present invention will be described below with reference to embodiments shown in the drawings.
FIG. 1 shows an external view of an embodiment of the device of the present invention when a cassette is used.

In the figure, 1 is a cassette, 2 is a cassette holder lid 2
A switching slider is slidably attached to 5. 3 is a recording button, 4 is an operating lever, 5 is a built-in microphone, and 6 is a counter.
Set the switching slider 2 to the cassette side as shown by the arrow.

FIG. 2 shows the above device in a state in which a magnetic card is used.

In the figure, the switching slider 2 is set on the card side as indicated by the arrow, and the magnetic card running groove 7 is opened, into which the magnetic card 8 is inserted.

Note that 9 is a magnetic medium. FIG. 3 shows the main mechanical parts of the device of the present invention (recording state).

In the figure, reference numeral 10 denotes a switching ring, which is interlocked with the switching slider 2 via a coupling pin 11, as shown in FIG.

The switching link 10 is connected to an arm 13 having a card pressing roller 12 at one end, and is further connected to a support 14 of the arm 13.
It is connected to the switching lever 15 via.

Reference numeral 16 denotes a card recording link which is linked to a switching lever 15, and the tape guide receiver 19 is moved by the switching lever 15.

A capstan 20 is driven by a motor (not shown), which cooperates with a pinch roller 21 to cause the magnetic tape (not shown) or magnetic card 8 from the cassette 1 to run at a constant speed.

At this time, an erasing head 24 and a recording/reproducing head 22 are placed on a moving board (not shown), and a tape guide 23 is provided near these heads so as to be slidable relative to the board.
is moved in the direction of the capstan 20.

Now, when recording on the magnetic card 8, as shown in FIG. 2, when the switching slider 2 is set on the card side as shown by the arrow, the switching link 10 is driven in the direction of the arrow 18, and the arm 13, The switching lever 15 and the card recording link 16 take the positions indicated by solid lines, respectively.

The card recording link 16 then activates the motor drive circuit (not shown).

Thus, when the magnetic card 8 is pressed against the recording/reproducing head 22 by the card pressing roller 12 and inserted up to the capstan 20 and the pinch roller 21, the magnetic card 8 is driven at a constant speed by the capstan 20, and desired magnetic recording is performed. It will be done.

In this case, the tape guide receiver 19 is connected to the switching lever 1.
5, the tape guide 23 is moved to the position shown by the solid line, and the tape guide 23 is prevented from advancing to the tape guide position, so that there is no problem in card insertion.

Next, when recording on the magnetic tape of the cassette 1, the switching slider 2 is set on the tape side as shown by the arrow, as shown in FIG.

As a result, the switching link 10 is driven in the direction of the arrow 17, and the arm 13, switching lever 15, recording link 16, and tape guide receiver 19 take the positions indicated by the dotted lines.

At this time, the recording/reproducing head 22 is still in the retracted position, so the card pressure contact roller 12 rotates as shown by the dotted line and comes out of the tape running path to a position where there is no obstruction.Then, the cassette 1 is inserted and the recording button is pressed. When 3 is pressed, the head advances to the recording position and the tape guide 23 advances to the tape guiding position, so that recording on the magnetic tape is executed.

As is clear from the above explanation, according to the present invention, recording and playback can be performed selectively on a magnetic card and a cassette tape with a single action by operating only the switching slider built into the cassette holder, making it extremely easy to operate. improves.
