Abstract

PURPOSE:To prevent an end part of a card cleaning member from being caught at the time of inserting a card by making the winding direction of the cleaning member the forward winding direction to the card inserting direction. CONSTITUTION:When the card C is inserted into the device from an inserting hole 1a, dirt of the surface of the card C is removed by the cleaning member 3 wound around a cleaning roller 2, and then recording or reproducing is performed after passing the card C between a driving roller 7 and a driven roller 8. In this case, since the winding direction of the cleaning member 3 wound around the cleaning roller 2 is in the forward winding direction to the card inserting direction, and moreover, the number of turns of the cleaning member 3 to be wound is more than one turn, when the card C is inserted, the card is carried forward without being caught by the end part of the cleaning member 3. Then, any number of turns is applicable if it exceeds one turn.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for removing dust and the like adhering to the surface of a card, and more particularly to a cleaning device for a card type information recording medium for cleaning the surface of a card type information recording medium. is there.

[0002]

2. Description of the Related Art Conventionally, an information recording / reproducing apparatus for a card-type information recording medium may not be able to accurately record / reproduce information due to dust or the like adhering to the surface of the card. It has a built-in cleaning device.

This cleaning device is composed of a pair of a cleaning roller around which a cleaning member is wound and a driven roller. When a card is inserted, the card is pinched between the cleaning roller and the driven roller and moves. , A mechanism for cleaning the surface of the card.

[0004]

In the above-described conventional cleaning device, the cleaning roller does not rotate when the card is inserted or rotates in the opposite direction to the card insertion direction, and the driven roller moves forward in the insertion direction. Turn to. On the other hand, when the card is discharged, both the cleaning roller and the driven roller rotate in the forward direction with respect to the card discharging direction.

Since the roller operates as described above, if the cleaning member wound around the cleaning roller is wound in the direction opposite to the card insertion direction, and the end end face of the cleaning member faces the card insertion slot. When the card is inserted, the leading end of the card is caught on the end surface of the cleaning member, and the end of the cleaning member is peeled off from the roller.

The present invention has been made in order to improve the drawbacks of the prior art, and the winding direction of the cleaning member wound around the roller for cleaning the surface of the card type information recording medium is set to the card insertion direction. An object of the present invention is to provide a cleaning device for a card type information recording medium in which the end portion of the cleaning member is not caught by the card when the card is inserted by winding the card in the forward direction. It is another object of the present invention to provide a cleaning device in which the end of the cleaning member does not come off from the cleaning roller when the card is inserted into the end surface of the cleaning member.

[0007]

That is, according to the present invention, in a cleaning device for cleaning the surface of a card type information recording medium with a roller, the direction of winding of the cleaning member wound around the roller for cleaning the surface of the information recording medium is The card-type information recording medium cleaning device is characterized in that it is wound in the forward direction with respect to the insertion direction of the card.

Further, in the present invention, it is preferable to use a cleaning roller having a cleaning member wound around the roller so that the number of windings of the cleaning member wound around the roller exceeds at least one. Further, it is desirable that the roller around which the cleaning member is wound does not rotate when the card is inserted into the cleaning device, but can rotate in the forward direction and the forward direction when the card is ejected. The cleaning device of the present invention can be installed in the recording / reproducing device for the card type information recording medium.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to illustrated embodiments.

Embodiment 1 FIG. 1 is a schematic sectional view showing an embodiment of a cleaning device for a card type information recording medium of the present invention. In the figure, an insertion slot 1a for a card C is provided on the left side of the apparatus main body 1, and a cleaning roller 2 and a driven roller 6 facing the cleaning roller 2 are provided on a card conveyance path inside the apparatus main body 1. Further, a driving roller 7 and a driven roller 8 facing the driving roller 7 are sequentially installed.

A cleaning member 3 is wound around the cleaning roller 2 in the forward direction with respect to the card insertion direction. Further, a ratchet wheel 4 is provided coaxially with the cleaning roller 2, and the ratchet stopper 5 prevents the cleaning roller 2 from rotating when the card C is inserted.

In such a structure, when the card C is inserted through the insertion opening 1a, the cleaning member 3 wound around the cleaning roller 2 cleans the surface of the card C, and then the drive roller 7 and the driven roller 8 are cleaned. After passing through the space, recording or reproduction is performed. At this time, since the cleaning member 3 wound around the cleaning roller 2 is wound in the forward direction so as to face the card insertion direction, and the number of windings exceeds 1, the card C is Even if inserted, the card C is conveyed without being caught by the end of the cleaning member 3. Further, in the embodiment, the number of turns of the cleaning member is slightly more than one, but if the number of turns is more than one, any number of turns may be used.

FIG. 2 is a schematic sectional view showing the card ejecting operation in the first embodiment. When the card is discharged, the ratchet stopper 5 is released and the cleaning roller 2 is rotated in the forward direction with respect to the card discharging direction. Therefore, the card C is not caught even when the edge of the cleaning member 3 is hit.

The cleaning member is not particularly limited and may be a commonly used one, and examples thereof include a woven structure cloth, a knit structure cloth or a non-woven cloth using ultrafine synthetic fibers.

[0015]

As described above, in the cleaning device of the present invention, the cleaning member wound around the cleaning roller is wound in the forward direction with respect to the card insertion direction.
There is an effect that when the card is inserted, it is not caught on the end surface of the cleaning member, and the card is not caught on the end surface of the cleaning member and the end portion of the cleaning member is peeled off from the cleaning roller.
