Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cleaning device for visibly recording information on a card for use, and for cleaning the surface of a recycled card so that the visible information already recorded can be erased and reused.

[0002]

[Prior art]

 Conventionally, a card such as a prepaid card is provided with a magnetic recording material layer, and the recorded information is read each time the card is used. Information will be written. Since such information is not displayed visually, the card user cannot see what the current card balance is. Therefore, a visible recording material layer is provided.

As this type of recording material, for example, an irreversible thermosensitive recording material described in JP-A-2-50897 is known. This utilizes the fact that the light transmittance at normal temperature changes due to heat treatment at a specific temperature.It is selectively heated to a specific temperature by a selective heating means such as a thermal head, so that the transparent part and the cloudy part are removed. It is generated and records visible information. For erasing, it suffices to uniformly heat the thermal head at any specific temperature, and new information can be recorded in this way. If necessary, a thin overcoat layer of epoxy resin, silicon resin, etc. is provided on the heating surface of the reversible thermosensitive recording material layer, and the recycle card is conveyed so that the surface contacts the thermal head. It is like this.

[0004]

[Problems to be solved by the device]

 However, when erasing this visible information, if the surface of the card is stained with dirt, dust, etc., the heat of the erasing thermal head will not be completely transmitted, and the visible information will not be partially erased, Therefore, there is a problem that the new record becomes unclear.

The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to remove dirt on a card to be conveyed with a simple configuration without adding a complicated cleaning device. It is to provide a cleaning device for a recycling card.

[0006]

[Means for Solving the Problems]

 The present invention relates to a device for erasing recorded visible information and cleaning the surface of a recycle card that is repeatedly used. The above object of the present invention is to provide a thermal recording material layer capable of writing and erasing visible information by heat treatment. A first roller for transporting the recycled card, a second roller facing the first roller and provided with a predetermined gap narrower than the thickness of the recycled card; And one drive means for driving the second roller and the drive transmission for transmitting the rotational movement of the drive means to rotate the first roller and the second roller at different peripheral speeds. Means for making the coefficient of friction of the first roller with respect to the recycle card larger than the coefficient of friction of the second roller, and the second car is provided with the recycle car. It is achieved by recycling the card in which the surface of the to have the function of cleaning the cleaning device. Further, the first and second rollers may be rotated at different peripheral speeds by using separate driving means.

[0007]

[Action]

 The driving force of one drive means is transmitted by the drive transmission means such that the peripheral speeds of the first and second rollers facing each other are different, and the friction coefficient between the recycling card and the first roller is the same as that of the recycling card and the second roller. The coefficient of friction between the rollers should be greater than that of the rollers, so that the driving force of the first roller conveys the recycled card, and the second roller has a cleaning function for cleaning the surface of the recycled card. The slippage caused by the speed difference between the recycle card and the second roller surface uniformly cleans the entire surface of the recycle card.

【Example】

 FIG. 1 shows the main configuration of the present invention, in which a card 1 passes through a gap between a driving roller 2 (corresponding to a first roller) and an opposing roller (corresponding to a second roller) and is appropriately pressed. It is carried and transported. On the other hand, the rotation of the drive motor 4 is transmitted to the drive roller shaft 6 and the opposing roller shaft 7 via the drive transmission means 5 described later. At this time, the peripheral speed V1 of the driving roller 2 is set to be higher than the peripheral speed V2 of the opposing roller 3, for example. 2 and 3 show an example of the drive transmission means 5. In FIG. 2, the rotation of the drive motor 4 is transmitted via the belt 8 to the pulley 9 which is fixed to the drive roller shaft 6 to rotate the drive roller 2 (not shown). The drive roller shaft 6 has a gear 10 fixed thereto, and the counter roller 3 (not shown) is rotated by meshing with a gear 11 fixed to the counter roller shaft 7. Further, FIG. 3 is the same as the example of FIG. 2 up to the point where the drive motor 4 rotates the drive roller shaft 6, but the pulley 12 and the opposing roller shaft 7 are fixed to the drive roller shaft 6. Drive is transmitted to and from the pulley 13 which is axially fixed by a belt 14 stretched in a plow shape. In FIG. 3, the positional relationship among the driving roller 2, the opposing roller 3 and the card is indicated by broken lines.

In the above embodiment, one drive motor 4 is used and the drive roller 2 and the counter roller 3 are rotated by the drive transmission means 5. However, as shown in FIG. You may rotate using the separate drive motors 15 and 16. In this case, the speeds of the drive motors 15 and 16 can be adjusted.

The driving roller 2 is selected from a material having a large friction coefficient, such as rubber, in order to enhance the carrying force of the card 1. Further, the opposing roller 3 is made of a material suitable for wiping dirt off the surface of the card. For example, it is very effective to wind a cleaning cloth of fine fibers such as nylon, which is used for cleaning glasses, around the surface.

In such a cleaning device, cleaning of the card is performed as follows. In FIG. 1, the conveyed card 1 is held by a driving roller 2 (first roller) and a counter roller 3 (second roller), and receives a pressure P corresponding to the gap. At this time, the friction coefficient of the first roller is μ1, the peripheral speed is V1, the friction coefficient of the second roller is μ2, the peripheral speed is V2, and μ1> μ2 and V1> V2 are satisfied. , The friction force μ1 · P acting between the lower surface of the card 1 and the first roller is larger than the friction force μ2 · P acting between the upper surface of the card 1 and the second roller. By the driving force of the first roller, the sheet is conveyed at a speed close to V1. Since V1 and V2 are different, a slip corresponding to the speed difference (V1-V2) occurs between the card 1 and the second roller. The slip friction force μ2 · P wipes the upper surface of the card. Further, the contact surface with the card 1 is constantly changed by rotating the second roller, and the entire roller is used uniformly. Note that V 1 <V 2 may be satisfied if μ 1> μ 2.

[0012]

[Effect of device]

 As described above, according to the recycling card cleaning device of the present invention, the card can be moved at a constant speed by the first roller with a simple structure in which a pair of rollers having different relative speeds are added to the card conveying path. There is an excellent effect that the card is stably fed and cleaned by feeding and wiping the constant frictional force with the second roller.
