Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a foreign matter removing device in a card manufacturing device used for manufacturing cards such as ID cards, optical cards, IC cards, cash cards, and prepaid cards.

[0002]

[Prior Art]

 Conventionally, as a card manufacturing apparatus used for manufacturing an ID card or the like, as described in JP-A-1-208193 or JP-A-64-4368, a single thermal head is provided, In some cases, the card-shaped recording medium encoded by the manufacturer is supplied and the card-shaped recording medium is subjected to required printing and then overcoated.

In the above-described card manufacturing apparatus, if foreign matter such as dust adheres to the surface of the card-shaped recording medium, the print quality of the thermal head deteriorates and defective cards increase. Therefore, a foreign matter removing device as shown in FIG. 8 is incorporated in a part of the card manufacturing device. This foreign matter removing device has a schematic configuration in which a pair of rollers 200, 201 having an adhesive surface is attached to one holder 202, and the holder 202 is detachably and swingably engaged with a base 204 via a shaft 203. In addition, the hook 206 attached to the base 204 is locked to the shaft 205 provided at the lower end of the holder 202, and the release lever 207 is operated to rotate the hook 206 against the spring 208. The structure is such that the locked state with the shaft 205 can be released and the two rollers 200 and 201 together with the holder 202 can be removed.

[0004]

[Problems to be solved by the device]

 When the foreign matter removing device is used to some extent, foreign matter adheres to the roller and its ability to remove foreign matter decreases. It is necessary to recover, but if a pair of foreign matter removal rollers were attached to one holder, cleaning would be troublesome and foreign objects could not be dropped sufficiently. In addition, since the conventional foreign matter removing device does not have a roller driving mechanism itself, it is placed in an extremely narrow space between two mechanisms having a driving function and the card-shaped recording medium is driven by the driving force of an adjacent mechanism. The card-shaped recording medium has to be drawn out from between the pair of foreign matter removing rollers while being fed between the pair of foreign matter removing rollers, and the degree of freedom in layout is extremely limited. Furthermore, the conventional structure is complicated, cannot be used for general purpose products, and is expensive.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention provides a pair of foreign matter removing rollers provided in the middle of a card-shaped recording medium conveying line of a card manufacturing apparatus for manufacturing a card by performing required printing on a card-shaped recording medium. One of the pair of foreign matter removing rollers of the foreign matter removing device having the above is detachably attached to a swingable holder, and the other foreign matter removing roller is detachably attached to a holder different from the holder.

[0006]

[Action]

 By passing the card-shaped recording medium through a pair of foreign matter removing rollers, it is possible to remove the foreign matter adhering to the surface of the card-shaped recording medium, and one of these foreign matter removing rollers is detachably mounted on a swingable holder. Therefore, if foreign matter is accumulated on the foreign matter removal roller, the holder can be swung to remove the foreign matter removal roller from the holder for easy cleaning.

This card manufacturing apparatus includes a paper feeding unit 1 for storing and feeding a large number of card-shaped recording media C used for printing, a reader / writer unit 2 for magnetically recording the card-shaped recording media C, and a card-shaped recording. A print unit 3 for printing images, characters, etc. on the medium C, an overcoat unit 4 for printing a protective film on the card-shaped recording medium C after printing, and a printed and overcoated card-shaped recording medium C are stored. A stocker 5 and a transport unit 6 for sequentially transporting the card-shaped recording medium C supplied from the reader / writer unit 2 to the print unit 3, the overcoat unit 4, and the stocker 5. A foreign matter removing device 9 according to the present invention is provided between the paper feeding unit 1 and the reader / writer unit 2.

The paper feeding unit 1 sends out a large number of card-shaped recording media C stored in the card storage unit 11 to the reader / writer unit 2 one by one by a paper feeding roller 12 or the like. The reader / writer unit 2 records predetermined data when the card-shaped recording medium C fed from the sheet feeding unit 1 via the foreign matter removing device 7 described later has a magnetic stripe, and the recording is performed reliably. After confirming that it has been broken, it is sent to the changer unit 7 of the transport unit 6.

The print unit 3 is stretched between a stage 31 on which a card-shaped recording medium C is placed and which is delivered to and from the transport section 8 of the transport unit 6, and a delivery roller 32 and a take-up roller 33. The thermal head 35 is provided with a transfer film 34 on which the meltable or sublimable inks of yellow (Y), magenta (M), and cyan (C) are applied at a predetermined pitch. The overcoat unit 4 is stretched between a delivery roller 42 and a take-up roller 43, and a stage 41 on which a card-shaped recording medium C is placed and delivered to and from the transport section 8 of the transport unit 6. It is provided with an overcoat film 44 impregnated with a heat-melting resin or the like serving as a protective film, and a thermal head 45.

The transport unit 6 includes a changer unit 7 that transforms the transport direction of the card-shaped recording medium C supplied from the reader / writer unit 90 by 90 °, positions the card-shaped recording medium C, and then sends it out. The transport unit 8 transports the recording medium C sequentially, and the transport unit 8 includes an endless belt 83 stretched between rollers 81 and 82.

As shown in FIG. 2, the foreign matter removing device 9 is provided at the front end of the frame 13 of the paper feeding unit 1, the holder 91 is pivotally supported on the frame 13 by a shaft 92, and the holder 93 is lowered by a spring 93. The shaft of the foreign matter removing roller 94 having an adhesive outer peripheral surface is detachably mounted in the groove 91a formed in the holder 91. Further, a notch 91b is formed in the holder 91 as shown in FIG. 7, so that it can be seen at a glance how much foreign matter is accumulated on the foreign matter removing roller 94.

Further, another holder 95 is fixed to the frame 13, and a shaft of a foreign matter removing roller 96 having an adhesive outer peripheral surface is detachably mounted in a groove 95a formed in the holder 95. A hook 97 for holding 96 in the groove 95a is swingably attached to the holder 95, and a spring 98 urges the tip of the hook 97 to contact the roller 96.

A gear 101 meshing with a gear 100 rotated on the side of the sheet feeding unit 1 is rotatably mounted on a holder 95, and a gear 102 mounted on a foreign matter removing roller 96 is meshed with this gear 101.

Next, the operation of the foreign matter removing device 9 in the card manufacturing device configured as described above will be described. As shown in FIG. 5, the feed rollers 16 and 17 are rotationally driven by the motor 15 of the paper feeding unit 1. The card-shaped recording medium C sent out from between the spaces is split between the foreign substance removing rollers 94 and 96 of the foreign substance removing device 9, and the roller 96 is geared by the gear 100 to which the rotational force of the motor 15 of the paper feeding unit 1 is transmitted. By being rotationally driven through 101 and 102, the card-shaped recording medium C is sent from the foreign matter removing device 9 between the rollers 21 and 22 which are rotationally driven by the motor 21 of the reader / writer unit 2.

As the card-shaped recording medium C passes between the foreign matter removing rollers 94 and 96 in this way, dust adhered to the surface of the card-shaped recording medium C due to the surface adhesive force of the foreign matter removing rollers 94 and 96. Foreign matter such as adheres to the surfaces of the rollers 94 and 96 and is removed.

At this time, the foreign matter removing roller 94 is held by the swingable holder 91 and is urged toward the foreign matter removing roller 96, so that the card-shaped recording medium C smoothly moves between the rollers 94, 96. While being able to enter, the surfaces of the rollers 94 and 96 are pressed against the surface of the card-shaped recording medium C, and the adhesive force of the rollers 94 and 96 is sufficiently exerted. In addition, the vertical thrust function is not required and a general-purpose product can be used, and the cost can be reduced.

When foreign matter is removed from the surfaces of the foreign matter removing rollers 94 and 96 due to repeated foreign matter removing operations to reduce the adhesive force, the holder 91 is lifted up against the spring 93 as shown in FIG. By doing so, the foreign matter removing roller 94 is removed from the groove 91a of the holder 91, and the hook 96 is released to remove the foreign matter removing roller 96 from the groove 95a of the holder 95. By returning the foreign matter removing rollers 94 and 96 to their original positions, the foreign matter removing function can be restored.

By disposing the foreign matter removing device 9 between the paper feeding unit 1 and the reader / writer unit 2, it is possible to reduce printing defects and prevent foreign matter from entering the reader / writer unit 2. It can be prevented.

[0020]
