Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a tape recorder that also serves as a card reader.

It is a print of letters and pictures that have recently been developed for the purpose of language education for young children. Recognized.

However, such magnetic cards require a dedicated card reader in order to reproduce the contents of the tape.

On the other hand, there has recently been an increasing demand for tape recorders for language practice such as English conversation.

Therefore, if the user wants both the above-mentioned magnetic card and tape recorder, the card league and the tape recorder must be purchased separately, which poses an inconvenient financial burden for the user.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an economically advantageous tape recorder that can also be used as a magnetic card reader.

Hereinafter, one embodiment of the present invention will be described with reference to FIGS. 1a, b to 3a,
This will be explained according to b.

By the way, this embodiment shows an example in which the present invention is applied to a microcassette tape recorder that has recently become popular. In FIGS. 1a and 1b, 1 is a tape recorder main body, and this tape recorder main body 1 is provided with a cassette chamber 2 into which a cassette tape (not shown) is loaded. A lid 3 is provided over the opening of the cassette chamber 2. Also provided within the cassette chamber 2 are a campstan shaft 4 for driving the tape, and a pinch roller 5 and a magnetic head 6 that move forward and backward relative to the shaft 4 in conjunction with, for example, a playback button (not shown). (In the illustrated example, the camp stun shaft 4
This shows a reproducing state in which the pinch roller 5 is supported.
) Furthermore, a bottom plate 8 is provided at the bottom of the cassette chamber 2. A guide groove 7 is formed in the bottom plate 8 along its middle direction. This guide groove 7 guides the running of the magnetic card 9, and allows the magnetic card 9 to pass between the tip of the magnetic head 6, the campstan shaft 4, and the pinch roller 5 when in the above-mentioned playback state. . In addition, the guide groove 7
The middle dimension is slightly larger than the thickness of the card 9. As shown in FIG. 2, the magnetic card 9 has, for example, characters printed in its center, and a magnetic tape 10 on which a conversation related to the characters is recorded is pasted along the lower side edge. On the other hand, the cassette chamber 2 at both ends of the guide groove 7
There are slits 11a, 11 on the side wall for inserting and removing the magnetic force cord 9.
b.

In the figure, 12 and 13 are cassette tapes (not shown)
14 is a guide pin for guiding the tape running of the cassette tape, and 15 is an eject button for the cassette tape. By the way, when recording, a tape recorder temporarily erases the contents of the tape using an erasing head while recording new contents using a recording head.

For this reason, if the magnetic card mentioned above is used by mistake while in this recording state, there is a risk that the recorded contents of the magnetic card will be erased. Therefore, the present invention is constructed as shown in FIGS. 3a and 3b.

Here, FIGS. 3a and 3b show the inside of the tape recorder main body of FIG. 1, and the same parts as in FIG. 1 are given the same reference numerals, and their explanation will be omitted. In the figure, reference numeral 16 denotes a sliding plate provided with the above-mentioned Vintiro roller 5 and magnetic head 6, and long holes 17, 17 are bored in the plate surface of this sliding plate 16. Pins 171, 171 provided on the chassis (not shown) of the tape recorder main body 1 are inserted through the holes 17, and the operation knob 18 moves in the direction of the holes 17, 17, thereby making the operation knob 18 freely movable. A substrate 20 is provided on the sliding plate 16 to which an erasing head 19 is mounted so as to be movable in these moving directions. In this case, the board 24 has long holes 21, 21 bored in its plate surface, and the pins 211 installed in the sliding plate 16 are inserted into these holes 21, 21, and the pins 211 are inserted in the direction of the holes 21, 21. 22, and is always tilted to the right in the figure by the imitation 22. A card restriction piece 23 is provided on the side surface of the board 20. This restriction piece 23 moves in the left-right direction in the drawing together with the board 20, and can close the card insertion side slit 11a of the guide groove 7 when moving in the left-hand direction in the drawing. On the other hand, 24 is an L-shaped lever, and this lever 24 can be rotated counterclockwise in the drawing in conjunction with the recording button 25.

Further, this lever 24 has its tip disposed close to the tip of the restriction piece 23, and is always in contact with the recording button 25.
When this operation is not performed, movement of the restriction piece 23 in the left direction in the drawing is restricted. Reference numeral 26 denotes a recording/playback switch which switches the tape playback circuit including the amplifier into the recording circuit in response to the rotation of the bar 24, that is, the recording operation.

However, according to such a mechanism, in the case of a playback operation, when the operation/button 18 is slid in the left direction in the figure from the state shown in FIG. 3a, the sliding plate 16 is moved in the left direction in the figure Move to.

However, in this case, the movement of the board 24 in the left direction in the drawing is restricted because the tip of the tip lever 24 of the card restriction piece 23 is in this direction. As a result, only the pinch roller 5 and the magnetic head 6 are pushed forward and set to the reproduction state (FIG. 1a). Therefore, in this state, the magnetic card can be used. Next, in the case of recording operation, see Figure 3 b.
As shown in the figure, when the recording button 25 is operated, the lever 24 rotates counterclockwise in the figure in conjunction with this operation.

Therefore, in this state, when the operation knob 18 is slid to the left in the drawing, the sliding plate 16 is moved to the left in the drawing, and the board 20 is also moved to the lever 24 which was in contact with the tip of the card restriction piece 23. Since the regulation of
6 to the left in the drawing. As a result, the erasing head 19 is pushed forward together with the pinch roller 5 and the magnetic head 6, and is set in the recording state (FIG. 1b). Further, at this time, as the card restriction piece 23 moves to the left in the figure, the slit 11a on the card insertion side is closed, making it impossible to use the magnetic card. As described above, according to the present invention, it can be used not only for recording and playback as a conventional tape recorder, but also as a card reader for playing magnetic cards, so there is no need to purchase a separate card reader as in the past, which is economical for the user. It is possible to reduce the burden on the middle school.

In addition, in the case of recording operation, the slit on the magnetic card insertion side can be closed by a card restriction plate, which prevents accidental use of the magnetic card while recording, and erases the recorded contents of the magnetic card. can be prevented.
Note that the present invention is not limited to the above-mentioned embodiments, and can be prevented without changing the gist. For example, in the above-mentioned embodiment, the erasing head is of the magnetic type, but if a wound type erasing head is used, the same parts as in Fig. 3 are shown in Fig. 4 with the same numbers. The erasing head 27 is attached to the sliding plate 16 as shown in FIG. Fusuma switch 26
An effect similar to that described above can also be obtained even if the erasing head 27 is energized by this. Furthermore, although the above-mentioned embodiments have been described with respect to a micro cassette tape recorder, the present invention can also be applied to a general compact cassette tape recorder. As described above, according to the present invention, it is possible to provide an economically advantageous tape recorder that can also be used as a card reader for magnetic cards.
