Abstract

PURPOSE:To effectively clean the contact surface of a card traveling path by forming adhesive parts on both sides of a card substrate with length longer than the card traveling path, and inserting and drawing out the card into/from the inserting opening of an information recording/reproducing device by a manual operation. CONSTITUTION:The shape of the card 30 is made rectangle-shaped, and the length in a card traveling direction is made longer. The adhesive parts 32 to attract dust or the like are formed on both sides of the card substrate 31, and further, a handle part 33 is attached to the short side of one side. Then, the front surface side, at least, of the adhesive part 32 is made to be transparent colored so that graduations 34a-34h printed on the center of the substrate 31 can be seen through. At first, the power supply of a whole device is disconnected, and the lock of a motor, etc., is released, and the card 30 is inserted 7 as handling the handle part 33 with fingers. Then, as confirming the graduations 34a-34h printed on the substrate 31, the insertion and the drawing- out of necessary length are repeated several times, and the dust and the contamination of rollers 13, 18-20, 21a-21d and a brush 8, a guide slope part, etc., being in contact with the adhesive part 32 are removed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a cleaning card for removing dust, dirt, etc. from an information recording/reproducing device using a card-shaped recording medium.

[Prior Art] In general, information recording and reproducing bags using card-like recording media come in two types: those with a card feeding mechanism and those without. , there is one in which the card is placed on a carrier and transported along with the carrier.

FIG. 5 is an example of direct transfer using rollers, and is a perspective view showing the main information reproducing part of an information recording and reproducing apparatus using an optical card. In FIG. 5, the optical head l indicated by the two-dot chain line has an LED (Light Emitting [
) jade), an illumination optical system 3, an imaging optical system 4, a mirror 5, and a line sensor 6, such as a COD, in which light receiving elements are arranged in the feeding direction X of the optical head 1.

A brush 8 is provided inside the insertion lower for removing dust etc. from the optical card C. A card insertion detection sensor 9 placed immediately after the brush 8 detects that the optical card C has been inserted and activates the electric motor. 10. electric motor 10
is connected to a drive roller gear 12 via a reduction gear 11, and a drive roller 13 is provided coaxially with this drive roller gear 12. Also, on the - side, the drive roller gear 12
is connected to a loading roller gear 17 via an idler gear 14, 15, 16 for transmitting driving force, and a loading roller 18 is connected to this loading roller gear 17.
are installed coaxially. Furthermore, pinch rollers 19 and 20 are provided above the drive roller 13 and the loading roller 18, respectively, so as to be located at one end of the optical card C in the X direction, and together with the pressing rollers 21a to 21d, pinch rollers 19 and 20 are provided to secure the optical card. C is pressed down from the top surface, and the optical card C is forcibly bent in a direction perpendicular to the surface. optical card C
A guide rail 22 is provided at the other end in the X direction, and the optical card C moves in the Y direction along a guide slope portion 22a that guides the forced curvature along a guide wall surface portion 22b. In addition, leaf springs 23a and 23b are installed at the side ends of the optical card C near the pinch rollers 19 and 20, respectively, and together with the pinch rollers 19 and 20, they urge the optical card C against the guide wall section 22b. . Card feed direction reversal sensors 24a and 24b are installed near both ends of the guide slope portion 22a in the Y direction, and detect the optical card C to reverse the rotation direction of the electric motor 10.

In the above configuration, the optical card C passes through the insertion lower,
When detected by the card insertion detection sensor 9, a controller (not shown) rotates the electric motor 1O based on the detection signal, and also rotates the loading roller 18 via the idler gears 14, 15, 16 and the loading roller gear 17.

By further inserting the optical card C in the direction of arrow Y, the optical card C is moved between the loading roller 18 and the pinch roller 20.
It begins to be sent in the direction of arrow Y. At this time, since the pinch roller 20 is provided only on the right side of the optical card C in the direction of travel in the X direction, the tip of the optical card C rotates to the left, and the left side edge of the optical card C 22 and is sent to the drive roller 13.

The optical card C is conveyed while being sandwiched between the holding rollers 21a and 21b, the drive roller 13, and the pinch roller 19. At this time, the optical card C is held against the guide wall portion 22 by the leaf spring 23a.
b, the entire right side end portion is pressed against the guide wall portion 22b, and the optical card C is pushed against the guide wall portion 22b.
In the 0th order, which is completely parallel to b, the optical card C is pressed by the pressing rollers 21c and 21d, so that the guide wall portion of the optical card C located on the upper surface of the pressing rollers 2Za to 21d and the drive roller 13 22b can create a surface with sufficient flatness for one track of at least several pm to several tens of ILm to the optical disc 1.

At this time, the rear end of the optical card C is connected to the guide slope portion 22.
a, the optical card C and the guide slope portion 22a are substantially parallel to each other. In this state, information is reproduced from the information recording surface Cts by the optical disc l, and the reproducing operation is repeated a predetermined number of times as detected by the card feeding direction reversal sensors 24a and 25b. Optical card C is sandwiched between 18 and pinch roller 20.
is sent back to the insertion lower.

In such a card transport mechanism using rollers, as the number of times the card is used increases, dust and the like may adhere to each roller, making the card running unstable. Therefore, as shown in Japanese Utility Model Publication No. 58-30295, for example, cleaning cards for removing dust from drive rollers have been proposed in magnetic card leagues and the like. However, in such an information recording/reproducing device, there is a limit to the depth of focus of the optical system, so not only the speed unevenness when the card is running, but also the
Irregular vibrations in the vertical direction also pose a serious problem. Therefore, the driven rollers 19, 20, 21a to 21d shown in FIG.
It is necessary to remove the dust that has adhered to the Further, the brush 8 provided in the insertion lower also becomes dirty as the number of times it is used increases, and conversely there is a problem in that it stains or damages the surface of the optical card.

Furthermore, conventional cleaning cards are approximately the same size as storage media cards, and are used by inserting them from the insertion lower in the same way as for normal recording and playback, and removing dust as they are transported by the driving force of the rollers. The drawback is that it cannot be used in systems such as optical card leagues that generally do not allow the insertion of different types of cards.

[Object of the Invention] An object of the present invention is to provide a cleaning card that improves the above-mentioned problems, easily and effectively removes dust and dirt from the card contact area, and enables stable card running. It is in.
