The dustproof shutter member 31 is held at the vertical closed position. Next, when the card is carried out, as shown in FIG.
From the right to the left of the drawing. The dust-proof shutter member 31 is pushed open by tilting in the direction opposite to the direction at the time of insertion by the transport force at the time of carrying out.

Subsequently, as shown in FIG. 7, the unloading operation of the feed rollers 35 and 36 forces the double insertion preventing shutter member 22 to be pushed open. Further, as shown in FIG. 8, when the card 100 comes off the feed roller 43, the feed roller arm 41 is tilted clockwise by the urging force of the coil spring 44. As a result, the double insertion preventing shutter member 22 is forcibly opened via the intermediate member 51. When the leading end of the card 100 approaches the double insertion preventing shutter member 22, the dustproof shutter member 31 returns to the vertical closed position as shown in FIG.

Thus, according to the present embodiment, the card 1
Until 00 is inserted, the double insertion preventing shutter member 22 for preventing double insertion is forcibly opened, while the dustproof shutter member 31 is held at the closed position. When the card 100 is inserted into the apparatus, the shutter member 22 for preventing double insertion is inserted into the card insertion slot 21a of the card insertion member 21.
To prevent double insertion of the card and prevent intrusion of dust. In this case, the inclination of the feed roller arm 41 is changed according to the thickness of the card 100, and the double insertion prevention shutter member 22 is switched between the open position and the closed position in accordance with the change, thereby simplifying the component shape. It is possible to eliminate the need for a sensor for preventing double insertion of a card.

[0026]

As is apparent from the above description, according to the first aspect of the present invention, the double insertion preventing shutter for opening and closing the card insertion slot utilizing the thickness of the inserted card is opened and closed. By switching to the position, the component shape can be simplified as compared with the conventional device, and a sensor for preventing double insertion of the card can be eliminated, thereby greatly simplifying the configuration. An information recording / reproducing apparatus can be provided.

According to the second aspect of the present invention, the shutter for preventing double insertion from the information recording medium after the state in which the information recording medium is sandwiched between the mounting surface of the information recording medium and the feed roller is released. Since the members are separated from each other, there is an advantage that the information recording medium arrives at the double insertion preventing shutter member in a state in which preparation for carrying out is completed.

According to the third aspect of the present invention, the information recording medium is transported so as to forcibly open the double insertion preventing shutter member urged in the direction to close the opening of the card insertion member. For example, it is possible to prevent an accident that the information medium cannot be taken out due to a malfunction of the double insertion prevention shutter member or the like.

According to the fourth aspect of the present invention, since the shutter member for preventing dust is provided, even if the shutter member for preventing double insertion opens the opening, the effect of reliably preventing dust from entering can be obtained. .
