[0004]

[Problems to be solved by the device]

 However, in the reader of the former card reader, the transport mechanism that transports the card is an endless belt, so if the detection mechanism optically reads the data on the card, it will stick to the card. Dust that adheres to the belt will be carried to the detection mechanism as the belt rotates and will adhere to the detection surface, making it impossible to read data in a short period of time.

In the reader of the latter card reading device, since the hole and the brush are arranged at the exit of the card transport path, the detection mechanism detects the data on the card outside the reading device by the glass fiber bundle. If the dust that adheres to the card is metal powder or sand dust, it will damage the glass fiber bundle that is in contact with the card, making it impossible to read data.

An object of the present invention is to provide a card reading device that can reliably read data for a long period of time even if the detection mechanism optically reads the data on the card. is there.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the card reader of the present invention has a member forming a card transport path having an entrance at one end and an exit at the opposite end, and a card along the transport path from the entrance to the exit. It is equipped with a transport mechanism located between the entrance and the exit to move the card, and a detection mechanism located in a part of the card transport path to read the data on the card traveling the card transport path. However, the transport mechanism is composed of a group of rollers arranged on both sides of the card transport path, and a plurality of groups are arranged along the card transport path, with two rollers rotating in opposite directions as one set. Is placed at a position to be the upper surface of the card in the transport path of the card, the member forming the card transport path contacts the lower surface of the card at the entrance, and the member forming the card transport path has a hole It is allowed to include a brush in contact with the opposite surface of the position and and cards to the flow side.

[0008]

[Action]

 When the card is inserted into the entrance, the roller moves the card by friction and carries it toward the exit along the conveyance path, and the detection mechanism reads the data on the conveyed card. However, with this card reader, when the card passes through the entrance, the dust attached to the bottom of the card falls into the holes, and the brush moves the dust on the top of the card as the card moves. Swipe toward the rear edge of the card, and when the rear edge of the card passes through the hole, drop the dust that has swept up into the hole to remove the dust on the top surface of the card that can be read by the detection mechanism, and then Even if the dust is sent to the detection mechanism and remains on the card, even if there is dust that adheres to the roller and does not adhere to the roller, it will fall in the space between the rollers and the dust will adhere to the detection mechanism. Moreover, since the dust attached to the roller is also separated from the adjacent member, the dust is not carried to the detection mechanism, and the detection mechanism is not damaged by the dust attached to the card.

【Example】

 As shown in FIG. 1, this card reader reads data from a mark card by inserting the mark card into a card reader 2 incorporated in the body 1 from a slit on the front surface of the body 1. Is read out and discharged from the slit in the upper part of the main body 1.

As shown in FIG. 2, the card reader 2 has a base 13 having a conveyance path for a mark card 12 formed by a card insertion guide 7 and a card running guide 8 and a mark card 12 along the conveyance path. It comprises a transport mechanism having a driving roller 3, a pressure roller 4, a driving roller 3 ', a pressure roller 4'and a pressure roller 6 for moving, and a detection mechanism 5 for reading the data on the mark card.

The card running guide 8 is fixed to the base 13. The card insertion guide 7 forms a gap related to the thickness of the mark card and is arranged at one end of the card traveling guide 8 and is fixed to the base 13 so that the card inserting guide 7 and the card traveling guide 8 carry a conveyance path to the mark card 12. Is formed. The drive roller 3 is arranged in an opening in the card running guide 8, and the shaft is held by a bearing in the base 13. The pressure roller 4 is held by a bearing in which the shaft is slidably inserted in a vertical groove in the base 13, and the peripheral surface thereof is pressed against the card insertion guide 7. The drive roller 3 ′ is arranged in the opening in the card running guide 8 and the shaft is held by the bearing in the base 13. The pressure roller 4'is held by a bearing whose shaft is slidably inserted in a vertical groove in the base 13, and its peripheral surface is pressed against the drive roller 3 '.

The reading head 5 is located between the pair of rollers and is arranged so as to be located on the upper surface of the mark card 12 to be conveyed, and is also attached to the base 13 via an L-shaped member. It is fixed. A bundle of glass fibers is incorporated inside the reading head 5. This bundle of glass fibers is incorporated in a case so that the detection surface at one end is located on the upper surface of the mark card 12, and the other end is optically connected to a detector external to this device. The pressure roller 6 is arranged with its peripheral surface facing the detection surface of the read head 5, and its shaft is held by a bearing in the base 13. The bearing is held by the base 13 so as to be vertically movable, and is pushed up by a spring to press the pressure roller 6 against the detection surface of the head 5. Although not shown, the drive roller 3 and the drive roller 3 ′ have shafts connected to the motor via a transmission mechanism.

Further, this card reading device is equipped with a mechanism for removing dust adhering to the mark card 12 when the mark card 12 is read. This mechanism consists of a dust drop hole 11 and a brush 10. The dust drop hole 11 is provided in the card traveling guide 8 at a position upstream of the drive roller 3 and the pressure roller 4 in the card traveling guide 8. A member bent into an L shape is arranged on the lower surface of the card traveling guide 8 and fixed to the base 13, and a dust box 9 communicating with the hole 11 is formed between the card traveling guide 8. The brush 10 is formed by bundling a large number of fibers, is arranged on the downstream side of the hole 11, and has a space smaller than the thickness t of the mark card 12 between its lower end and the surface of the card running guide 8. A member that is formed and holds the upper end is fixed to the support member of the read head 5, and can be attached to and detached from the base 13 together with the read head 5.

In this reading device, when the mark card 12 is inserted into the entrance formed by the card insertion guide 7 and the card running guide 8 as shown by the arrow A, the mark card 12 causes the driving roller 3 and the pressing roller 3 to press. The data on the upper surface of the mark card is read by the read head 5 while being sent to the read head 5 by the roller 4, pressed against the read head 5 by the pressure roller 6 and transferred, and then driven as indicated by an arrow B. It is sent out from the outlet formed by the rear end of the card running guide 8 by the roller 3'and the pressure roller 4 '. However, when the tip of the mark card 12 passes through the entrance formed by the card insertion guide 7 and the card running guide 8, dust attached to the lower surface of the mark card 12 falls into the dust box 9 from the hole 11. When the mark card 12 is further moved and the mark card 12 comes into contact with the brush 10, the brush 10 wipes dust from the upper surface of the mark card 12 and moves toward the rear end of the mark card 12 as the mark card 12 moves. When dust is swept away and the rear end of the mark card 12 passes, the dust is dropped into the dust box 9 through the hole 11 and the mark card 12 is moved to the reading head 5 without dust. Then, even if dust remains on the mark card 12, the dust adheres to the drive roller 3 or the pressure roller 4, and the mark card 12 is sent to the reading head 5 with no dust attached, and The dust adhering to the driving roller 3 and the pressure roller 4 is not conveyed to the reading head 5 or the pressure roller 6 because these rollers are independent of the reading head 5 and the pressure roller 6.
