Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a shutter mechanism for a card processing device that can prevent the insertion of a bent card.

[Conventional technology]

In general, card processing devices built into magnetic card type public telephones, etc., use a shutter mechanism to prevent further insertion of the card inserted into the card entry passage from the card insertion slot, thereby preventing fraudulent card fraud. After preventing the card from being used and determining that the card is a legitimate card by the card detection means, the card is taken in by pushing the card down with the card taking mechanism and removing it from the shutter mechanism.

[Problem that the invention attempts to solve]

However, the conventional shutter mechanism is fixed and locks both edges of the front end (insertion side end) of the card. There was an inconvenience that it was not possible to completely prevent the intrusion and the items were stored incorrectly. Additionally, movable shutter mechanisms are also known, but like fixed types, these mechanisms do not work effectively with bent cards or cards with weak backs, and may sometimes be stored incorrectly. Ta. Additionally, storing a bent card may cause the card to jam inside the device, causing a malfunction.

[Means for solving problems]

The shutter mechanism of the card processing device according to the present invention has been developed in view of the above-mentioned points, and includes a pair of left and right abutting walls on which both side edges of the card insertion end abut against both side walls of the card intake passage. At the same time, a shutter plate is disposed between these abutting walls and has a card entry blocking portion at one end extending below the card entry passage, and this shutter plate is interlocked with the card entry mechanism. The card receiving passage is opened by operating the card.

[Effect]

In this invention, the abutting wall and the shutter plate double prevent the card from entering any further.
To reliably prevent a bent card from being erroneously stored.

〔Example〕

Hereinafter, the present invention will be described in detail based on embodiments shown in the drawings.

FIG. 1 is a side sectional view of a card processing device equipped with a shutter mechanism according to the present invention, and FIG.
FIG. The present embodiment will be described using a magnetic card as the card and applying it to a magnetic card type public telephone as an example.

The card take-in passage 4 and the card return passage 6 are separated by a substantially triangular switching member 16, and communicate with the card processing conveyance passage 5 at the intersection thereof, that is, at the back end. In addition, the card insertion passage 4 is formed in a substantially square shape, so that the card insertion passage 4 is formed in a substantially square shape.
The first half 4a on the side is substantially horizontal, and the second half 4b on the side of the card processing conveyance path 5 is formed so as to be inclined from a position one step lower than the first half 4a, and the card taking mechanism 7 is on the front half 4a side. Further, the shutter mechanisms 8 are disposed at the innermost positions of the front half 4a.

The card take-in mechanism 7 includes a take-in roller 17 disposed above the front half of the card take-in passage 4;
a take-in lever 19 rotatably supported on a fixed shaft 18 and to which the take-in roller 17 is rotatably attached;
and a drive solenoid 20 that rotates this take-in lever 19 counterclockwise in FIG. 1 when taking in a card.
, and a take-in roller 22 which is arranged below and opposite to the take-in roller 17 and takes in the card 21 . In this case, as shown in FIG. 2, the take-in lever 19 is composed of a pair of left and right plates 23a, 23b, a pair of shafts 18, 24, and a connecting pin 25 (FIG. 1) that connect these plates. The taking-in roller 17 is disposed at 24, and one end of a return spring 26 is latched to provide a clockwise return behavior in FIG. 25 is pressed by the operating rod 27, and is rotated counterclockwise about the shaft 18 against the return spring 26, thereby pressing the take-in roller 17 against the take-in roller 22. ing.

The shutter mechanism 8 is provided with a pair of left and right abutting walls 30, 31, which are disposed on both sides of the card intake passage 4, and against which both edges of the insertion end of the card 21 abut, and is disposed between these abutting walls 30, 31. a shutter plate 32,
The shutter plate 32 is composed of a spring 33 and the like that gives the shutter plate 32 the ability to rotate counterclockwise in FIG. The pair of abutting walls 30 and 31 are disposed on the inner surfaces of a pair of left and right side plates 34 and 35 forming the card processing device 1 so as to be orthogonal to the card intake passage 4. On the other hand, the shutter plate 32 is a shutter holding member 3 that is horizontally suspended between the pair of side plates 34 and 35.
6 (see Fig. 1) so as to be rotatable in the left-right direction via a shaft 37, so that it is located above the card receiving passage 4, and one end thereof is normally provided with the abutment. The rear half 4b of the card receiving passage 4 extends below the walls 30, 31 as shown in FIG.
A card entry prevention portion 32a for blocking and closing the card is integrally provided, and the other end is pressed against the intermediate lower surface of the plate body 23b by the force of the spring 33.
Therefore, when the take-in lever 19 is rotated by the drive solenoid 20 during card take-in, the shutter plate 32 is pushed down by the plate body 23b, so that the spring 3 is moved around the shaft 37.
3 in the clockwise direction in FIG. 2, thereby the card entry blocking portion 32a rises to open the rear half 4b of the card intake passage 4.

Note that when the card 21 is taken in, it is pushed down by the upper take-in roller 17, and the card 21 is pushed down by the lower take-in roller 2.
2, even if the card receiving passage 4 is curved as described above, or even if it comes into contact with the pair of left and right abutting walls 30, 31 and is prevented from entering further, the shutter The card is reliably guided to the rear half 4b of the card receiving passage 4 through the lower part of the plate 32. In addition, the pair of abutment walls 30 and 31 and the card entry blocking portion 32a of the shutter plate 32 prevent the card 21 from being blocked.
Since the card 21 is doubly prevented from entering, even if the insertion end of the card 21 is bent, the card 21 will not be forcibly inserted any further.

The substantially triangular switching member 16 includes a pair of left and right plates 16a and 16b (16b is not shown) whose front end portions are rotatably supported on a shaft 40 that is horizontally suspended between the pair of left and right side plates 34 and 35 described above. ), and a spring and connecting pin 41 (not shown) that bias these plates 16a, 16b counterclockwise in FIG.
The rear end portions of the plates 16a and 16b normally prevent communication between the card intake path 4 and the card processing transport path 5, and allow the card processing transport path 5 and the card return path 6 to communicate with each other. The pair of plates 16a and 16b are disposed below the plates 23a and 23b to face each other, and are pressed by these plates 23a and 23b when the card is taken in, thereby causing the spring to move around the shaft 40. 1 in the clockwise direction in FIG. 1, the card taking-in passage 4 and the card processing conveyance passage 5 are communicated with each other, and the card processing conveyance passage 5 and the card return passage 6 are prevented from communicating with each other. ing.

The card transport mechanism 9 includes a plurality of transport pulleys 4 facing each other across the card processing transport path 5.
3a, 43b, driven pulleys 44a, 44b, conveyor belt 45, driven belt 46, the drive motor 1
2. It is composed of a reduction pulley 47, a tension pulley 48, a drive belt 49, a motor shaft pulley 50, etc., and the conveyor belt 45 and driven belt 46 sandwich the card 21 by transmitting the driving force from the drive motor 12. It is configured to be moved back and forth.

The card return mechanism 10 includes a card return passage 6
A conveyance pulley 43c and a return roller 55, the conveyance belt 45, a card return slot guide 56, and a card misinsertion prevention lever 57, which are arranged across the
etc., and the return conveying force is provided by conveying pulleys 43a, 43 driven by a conveying belt 45.
c, and a driven pulley 44 facing these pulleys.
a, and the return roller 55. Further, the card retrieval force of the card retrieval mechanism 7 is equal to the retrieval force of the return roller 5.
5 rotation is provided by a gear (not shown) integrally provided on one side of the mounting roller 22 and a gear (not shown) integrally provided on one side of the mounting roller 22 and meshing with the gear.

Note that the arrow directions shown in FIG. 1 indicate the rotation and running directions of various rollers, pulleys, and belts during card loading. Further, although a detailed explanation has been omitted, the punch mechanism 11 is for visually displaying the card record information (remaining power) remaining at the end of the call at a predetermined position on the card 21. 6
0 is a link lever that rotatably supports the transport pulley 43c, 61 is a rotating lever that rotatably supports the link lever 60, and 62 is a lever that urges the link lever 60 clockwise about the shaft 63. It is a spring that

Next, the operation in such a configuration will be explained.

FIG. 1 shows the state when the card is inserted. When the magnetic card 21 on which the remaining power is recorded in advance is inserted into the card insertion slot 2, the shutter mechanism 8
will prevent further entry. Further, as mentioned above, even if the card is bent or is a weak card, the card will not be forcibly inserted any further. When a detector (not shown) detects the insertion of the card 21 in this inserted state, a detection signal is sent to the control circuit, and the control circuit determines whether the card 21 has the correct shape, and if it is correct, issues a series of processing instructions. . Then, the driving solenoid 20 operates and the operating rod 27 presses the connecting pin 25.
The take-in lever 19 is rotated counterclockwise around the shaft 18, and at the same time rotates the shutter plate 32 clockwise around the shaft 37 in FIG. Rotate clockwise as shown in Figure 1. Therefore, the magnetic card 21 is pushed down by the take-in roller 17 and pressed against the take-in roller 22. The switching member 16 opens the card take-in passage 4 and closes the card return passage 6. Furthermore, due to the rotation of the shutter plate 32, the card entry blocking portion 32a moves above the card intake passage 4, thereby opening the passage 4.

The drive motor 12 rotates clockwise, and its driving force is transmitted to the reduction pulley 47 via the drive belt 49. Here, the conveyance pulley 43b coaxial with the deceleration pulley 47 is rotated clockwise, and the rotation is transmitted to the conveyance pulleys 43a and 4 via the conveyance belt 45.
3c and the driven pulley 46. The rotation of the transport pulley 43c is transmitted to the return roller 55 via the transport belt 45, and the rotation of the roller 55 is further transmitted to the take-in roller 22 via a gear. Therefore, the take-in roller 22 rotates clockwise and takes the card 21 into the interior along the card take-in path 4 by the take-in conveyance force, and is then held between the conveyor belt 45 and the driven belt 46 to process and convey the card. It is transported to Route 5.

When the leading edge of the card 21 reaches the magnetic head 13, the information reading process is confirmed. This is performed while the card 21 is being transported through the card processing transport path 5 at a constant speed by the card transport mechanism 9. After the card loading process, when a detector (not shown) detects that the rear end of the card 21 has passed over the top surface of the switching member 16, the drive solenoid 20 is restored to its original state by a control signal from the control circuit. As a result, the card loading mechanism 7, shutter mechanism 8, and switching member 16 are restored to the same state as before loading.

When the call ends, the card 21 is inserted into the magnetic head 1.
After the remaining power information and the like are recorded and confirmed in step 3, holes are punched on the card by a punching mechanism 11 as a visual display of the remaining power, if necessary, and the card is returned to the card return slot 3. The card 21 will be conveyed in the opposite direction from when it was taken in, but this is because the motor 12 rotates counterclockwise and the pulleys and belt rotate in the opposite direction to the direction of the arrow. Detailed explanation will be omitted.
