Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to an improvement of a card reader in which a shutter is provided inside a card insertion slot to prevent dirt, illicit use and erroneous operation inside.

[Conventional technology]

Conventionally, measures to prevent intrusion of dust, moisture, etc. from the card insertion port of a card reader and measures to protect the device from foreign objects or the insertion of two cards intentionally or inadvertently are required. It is made in Japanese Utility Model Publication No. 53-42433.

According to the above-mentioned proposal, as shown in FIG. 4, a card discriminating section 8 including a magnetic head, a pad roller 14, a shutter 9 ', a driving roller 7 and a driven roller 10 are arranged from the side of the insertion slot 4 side, and a magnetic field for recording / reading information at intervals. A head 11, a pad roller (not shown), a driving roller 12 and a driven roller 13 are arranged.

Then, in order to prevent an error in the reading or recording operation due to an erroneous operation or a mischief or to protect the inside of the card reader, the card 3 is taken into the shutter 9'and the reading or recording operation is performed with the shutter 9'closed. Need to let.

Therefore, the respective parts are arranged as described above, the distance from the insertion port 4 to the shutter 9'is A ', the distance from the insertion port 4 to the driving roller 7 and the driven roller 10 is B, and the shutter 9'for recording / reading. The distance to the magnetic head 11 is C ', for example, A' = Min30mm, C '= Min90mm, card length =
If it is set to 85 mm, the distance from the insertion slot 4 to the recording / reading magnetic head 11 cannot be shorter than the card length + A ', that is, 115 mm in practice due to the above reason, and the card reader cannot be made compact.

Also, if a drive roller is provided on the insertion port side of the shutter, if a card is taken in and another card is inserted into the insertion port during reading or recording, another card will hit the shutter and the load roller will be overloaded. There is a drawback that the card conveyance becomes abnormal and the reading or recording operation cannot be continued.

Furthermore, since the drive roller on the rear side of the shutter is deeper than the distance B from the insertion slot, the card must be inserted all the way in, and when the card is ejected after the operation, the amount of protrusion of the card from the insertion slot is small, It had some drawbacks, such as being difficult to grasp by hand.

[Purpose of device]

In view of the above drawbacks, the present invention proposes a card reader that is more compact, does not hinder reading or recording, is easy to insert a card in the insertion slot, and is easy to grip when returning the card.

[Constitution of device]

The present invention is provided with a card discriminating section and a shutter at the back of the card insertion slot. When a card is properly inserted, the shutter is opened and the card is fed to read or record information. A second shutter is provided which is opened and closed after the card is inserted, a card feed roller is provided between the second shutter and a shutter deeper than the card discriminating section, and the position of the magnetic head is set to the distance between the second shutter and the magnetic head. Is longer than the card length, and the distance between the shutter and the magnetic head behind the card discrimination unit is shorter than the card length.

〔Example〕

Hereinafter, the present invention will be described with reference to an illustrated embodiment. FIG. 1 shows a state in which a card is inserted into the insertion slot. In the card reader, a card insertion slot 4 and a passage 5 are formed by upper and lower magnetic card passage members 1 and 2 in FIG. A second shutter 6 is provided slidably up and down on the back side (just behind) of the card insertion slot 4.

A card discrimination unit 8 including a drive roller 7 and a magnetic head is provided on the back side of the second shutter 6. A first shutter 9 is provided at the back of the card discriminating section 8 so as to be slidable up and down. The driving roller 7 sandwiches the passage 5 and the driven roller 10
, And a pad roller (not shown) across the passage 5 faces the magnetic head arranged side by side with the driven roller 10.

Information is recorded at a distance from the first shutter 9
A read magnetic head 11 and a driven roller 13 are provided side by side. The driven roller 13 faces the drive roller 12 across the passage 5, and the magnetic head 11 faces a pad roller (not shown) across the passage 5. There is.

The distance from the insertion opening 4 to the second shutter 6 is A,
When the distance from the second shutter to the recording / reading magnetic head 11 is C and the distance from the first shutter 9 to the recording / reading magnetic head 11 is D, C> card length, D <card length, A = substantially the thickness of the magnetic card passage member, and the distance between the insertion slot 4 and the magnetic head 11 is shortened by A'-A as compared with the conventional example shown in FIG.

A regular card has a magnetic stripe, and in order to determine whether the card 3 is a regular card, the magnetic stripe of the card discriminating unit 8 must be read.

Therefore, the second shutter 6 is always open, and the card 3 can be freely inserted up to the card discriminating section. The first shutter 9 is always closed so that only a legitimate card can be taken into the card reader. (Closing the passage 5) When the card 3 is inserted into the insertion slot 4 as shown in FIG. 1, the card discriminating unit 8 and a sensor (not shown) determine whether the card is a legitimate card, and if it is determined to be a legitimate card. , Second
As shown in the figure, the first shutter 9 is opened by a signal from the card discriminating unit 8 and the drive roller 7 and the driven roller 10 feed the card 3 into the reader.

When the card 3 is fed and the rear end of the card 3 passes under the second shutter 6, the operation of a sensor (not shown) or the recording / reading magnetic head 11 is started and the second shutter 6 is opened as shown in FIG. To be closed.

When the second shutter 6 is closed, the drive roller 7 and the driven roller 10 are protected by the second shutter 6, and even if an attempt is made to insert a second card from the outside, the shutter is blocked and the information on the internal card 3 is read. Or, the recording is done without any trouble.

When the reading or recording of information on the card 3 is completed and the card 3 is conveyed in the direction of the insertion slot 4, the card discrimination unit 8 detects the return of the card 3, and the second shutter 6 is detected by this detection signal.
Is opened.

After that, the card 3 is sent to the insertion slot 4 by the driving roller 7 and the driven roller 10, and when the card 3 passes the position of the first shutter 9, a card position detection sensor (not shown) operates to close the first shutter 9 and The front side is ejected from the insertion port 4 by the driving roller 7 and the driven roller 10, and the card 3 stops at the position where the card 3 passes the driving roller 7. Since the card 3 stops at the position where the card 3 has passed the drive roller 7, the card 3 largely projects from the insertion port, and the card can be easily removed.

As long as the shutter plate does not damage the card 3, the first shutter 9 may be brought into contact with the card 3 so as to close the first shutter 9 in the ejected state before removal, and closed when removed.

As described above, when the second shutter 6 and the first shutter 9 are provided at an interval from the card insertion port 4 side and the card discriminating section 8, the driving roller 7 and the driven roller 10 are provided between them,
Since the shutter 6 is located at the back side shutter 9'position of the prior art (shown in FIG. 4), the position of the magnetic head 11 is brought closer to the insertion port 4, and the size of the card reader is shortened, and the size can be made compact.

In addition, since the amount of card protruding from the card insertion port is large when ejecting the card after operation, it is easy to remove the card.
The card is taken in at 10.

Further, when the second shutter 6 is closed as shown in FIG. 3, the drive roller 7 and the driven roller 10 are protected by the second shutter, and the second card cannot be inserted from the outside.
There is no trouble in reading or recording information on the internal card 3.

[Modification] In the above-described embodiment, the information written in the magnetic stripe is read by the magnetic head of the card discriminating unit 8 in order to determine that the card is a normal card. However, a mark is provided on the card 3 or a conductive metal foil is embedded. Alternatively, a different type of resin to be detected by the radiation source may be provided at a specific location and a corresponding card discriminating section may be provided.

[Effect of device]

Since the present invention is configured as described above, the dimension of the card reader in the running direction can be shortened.

Also, the amount of protrusion when ejecting the card is large, making it easy to pull out,
In addition, operability is good because the amount of card insertion is small.

In addition, the drive roller is protected by the second shutter, and a card reader having excellent practical effects such as no trouble in reading or recording information on the internal card because the second card cannot be inserted from the outside. Can be provided.
