A card 13 as shown in FIG. 2, for example, is stored in this card storage space.

The card 13 has, for example, a picture on the front side as shown in FIG.
Visual information 13a such as characters is displayed, and as shown in the opening of Figure 2, a recording/playback sheet H3b having, for example, an audio track is pasted on the back side.

Then, such a card 13 is turned with the front side facing up,
The aforementioned card insertion slot 11 of the recording/playback machine as shown in FIG.
It is inserted from a.

When the inserted card 13 is pushed further and the entire card is stored in the card storage space, the turntable inside the main body 11 automatically rotates, and the head moves along the audio track of the recording/playback screen 13b mentioned above. Audio is recorded on the card 13, or audio recorded on the card 13 is reproduced.

Further, since the visual information 13a of the card 13 stored in the card storage space is held so as to be visible through the transparent plate 12, the user of this recording/playback device can also read the visual information 13a along with the auditory information. They can be used simultaneously.

The recording/playback device shown in FIG. 1 includes a speaker 14 on the front right side of the main body 11, and a volume adjustment knob 1 on the top surface.
It is equipped with 5.

An eject button 16 is also provided on the top surface of the main body 11, allowing the card 13 to be taken out from the card storage space.

The card insertion type recording and reproducing machine is configured as described above, for example.

Conventionally, in this type of recording/reproducing machine, a card positioning structure as shown in FIG. 3 has been used.

What is indicated by the reference numeral 18 in FIG. 3 is a card storage space,
A first eject member 19 and a second eject member 20 are provided within the space 18 .

The second eject member 20 is formed in a dogleg shape, rotates around a central support shaft 21, and has a protruding piece 20a at one end and a sliding pin 20b at the other end.

The sliding pin 20 b fits into the dogleg-shaped slot 19 a of the first eject member 19 .

The dogleg-shaped slot 19a is an H-shaped first eject member 1.
9 Formed on one side.

On the other side of the first eject member 19, there is a support shaft 22 at the center.
A roller 23 is provided at the tip, and an operating rod of a plunger 24 is connected to the other end.

A tension spring 25 is hooked between the first eject member 19 and the second eject member 20.

Therefore, the card 26 enters the card storage space 1 from the direction of arrow a.
When the card 26 is inserted into the protruding piece 20, the lower edge of the card 26 is inserted into the protruding piece 20.
