Description

ORM card read-out device {DEVICE FOR READING AND BRANDING AN OMR CARD}

The present invention relates to a read-marking device for an OMR card, and more particularly, to minimize the working distance of an operator by having a Y-type card moving path and to significantly reduce card readability by applying a plurality of gap holding rollers. OMR which can be lowered and the main body is configured with two-stage opening / closing method, which reduces the stake in use, improves the convenience of jam removal and maintenance, and enables the automatic release of stamped tickets to realize unmanned operation. A card read-out stamping device.

In general, most conventional OMR card readers for reading the contents of an OMR (Optical Mark Reader) card have a linear movement path. In other words, the card introduced through the front opening of the device is made to be read while moving along a straight path, and then discharged through the discharge port provided at the rear of the device, the operator's moving copper wire is long, reducing work efficiency. Rather, the overall size of the device is increased, which requires a lot of installation space. Further, even in the reading process of the card, the gap between the optical sensor unit for recognizing the mark on the card and the card is not kept precisely, so the read rate of the card is high.

As one of the measures to improve this point, conventionally, an OMR card reading device having a U-shaped moving path has been developed instead of a straight moving path. However, since the device adopts an open structure for completely detaching the upper guide, It is not only very difficult for the operator to detach the guide, but there is a risk of loss and damage of the open guide. In addition, if the device is used for a long time, a lot of minute paper manipulation (stake) generated from the card is accumulated, and it is very difficult to remove the accumulated stake.

In addition, since the conventional OMR card reader has no unmanned driving mechanism, its use is not possible at an automated window that requires unmanned operation, which causes a large labor cost.

An object of the present invention for solving the above problems is in the OMR card reading apparatus having a Y-type card movement path, by applying a plurality of gap holding rollers can significantly lower the card read rate, the main body two-stage opening and closing method By effectively eliminating the equity generated during use, it is possible to carry out the jam removal and maintenance conveniently, and to automatically release the postmarked ticket (OMR card) to realize unmanned operation. The present invention provides a read stamping device for an OMR card.

Here, the main body constituting the OMR card reading sweep device is largely composed of three parts. That is, the lower part of the main body is driven by the rotational force of the drive pulley (3) mounted on the drive motor (2) and the drive motor (2) transmitted from the drive pulley (3) via the drive belt (V1) ( The base frame 36 provided with 3 ') is arrange | positioned. In addition, two upper frames 37 and 39 are mounted on the upper part so as to be engaged and disengaged by the locking means.

In the drawing, the first upper frame 37 on the left side is rotatably mounted to the base frame 36 by the first hinge shaft 38, and the second upper frame 39 on the right side is the second hinge shaft 40. Rotatingly mounted to the base frame (36) by means of the first upper frame (37) and the first inlet (1) through which the card is inserted and the first and second outlets for discharging the card is completed 28, 35, to provide a Y-shaped card transfer path. The locking means for detachably coupling the first upper frame 37 and the second upper frame 39 on the base frame 36 will be described in detail with reference to FIG. 3.

Next, the configuration of the drive system for transferring the OMR card along the Y-shaped transfer path provided by the base frame 36 and the first and second upper frames 37 and 39 by receiving power from the drive motor 2 is described. Explain. According to the drive system of the present invention, the first feed gear 5 engaged with the driven pulley 3 'described above and the fourth feed pulley 9 integrally mounted with the first feed gear 5 are transmitted. The first to third feed pulleys 6 to 8 and the first feed gear 5 to rotate the first to third feed rollers 12 to 14 by receiving the rotational force of the motor through the first transfer belt V2. ) And the rotational force of the motor transmitted to the second feed gear 29 and the fifth feed pulley 10 integrally mounted with the second feed gear 29 through the second transfer belt (V3). It consists of the fifth and sixth feed pulleys (10, 11) for rotating the pressing roller (17) and the fifth feed roller (16).

Here, the first to fifth feed rollers 12 to 16 are for conveying the OMR cards in the Y-shaped passages to the sweeping portion and the discharge port, and are provided with a plurality of idle rollers facing the feed rollers 12 to 15. 18 to 22) are further provided. That is, the first upper frame 37 is equipped with a gap holding roller 25 to maintain a constant gap between the OMR card and the optical recognition unit 24, so that the relative between the optical recognition unit 24 and the OMR card is maintained. Distance is always kept constant, improving readability. The second upper frame 39 is equipped with first to fifth feed rollers 12 to 16 which are in close contact with the OMR card moving along the drive system.

In addition, the first upper frame 37 is provided with first and second idler rollers 18, 19 facing the first and second feed rollers 12, 13, and the base frame 36 has a third. The third to fifth idler rollers 20 to 22, which are arranged opposite to the fifth to fifth feed rollers 14 to 16, are pressurized by the pressure springs 23, so that the OMR card moving along the drive system is properly applied. Close contact to ensure smooth movement.

Next, as shown in Fig. 2, when the configuration of the sweeping portion for sweeping the OMR card supplied by the drive system in accordance with the operation of the drive motor 2 is shown, the solenoid operated by electricity supplied from an external power source. 30, the first and second rotating plates 31 and 32 rotated according to the operation of the solenoid 30, and the rotating rollers 31 and 32 are introduced by the driving system while being rotated by the pressure roller ( A ticket printing head 33 for sweeping the brand onto the ticket pressed by 17) and a return spring 44 for restoring the ticket printing head 33 to its original position after sweeping.

Here, the first rotating plate 31 is connected to the rod 30a of the solenoid 30 by a pin 50 and is rotatably mounted about the hinge 51. In addition, the second rotating plate 32 connected to the first rotating plate 31 is rotatably mounted around the hinge 52. Therefore, when electricity is supplied to the solenoid 30 by the control unit C, the rod 30a of the solenoid is pulled downward in the direction of the arrow Q1, and the first rotating plate 31 and the second rotating plate 32 are rotated. By rotating in this order, as shown in FIG. 2B, the ticket printing head 33 is rotated along the direction of arrow Q2, and the brand is swept by the ticket interposed between the press roller 17. As shown in FIG.

The OMR card, which is completed in the postmarking part, is selectively released to either the first outlet 28 or the second outlet 35 according to an unmanned or manned driving method. The branching means was installed in the second guide G2 of 36). For reference, the main body is provided with a plurality of guides G1 to G4 for guiding the transfer of the OMR card. That is, the first guide G1 for guiding the card introduced into the inlet 1, as well as the second guide G2 and the second guide G2, are disposed to face the second outlet G2. A third guide G3 for guiding to 35 and a fourth guide G4 for guiding the card to the first outlet 28 are attached.

As the branching means for switching the direction of the card to send the OMR card introduced into the inlet (1) to the stamping unit or to discharge the OMR card stamped from the stamping unit to the second discharge port 35, in the present invention The branched body 27 which prevents back-stripping OMR card from flowing back into the inlet port 1 while being rotated about the hinge 64 by the pressure spring 26 is illustrated.

Here, since the branch body 27 is pressurized upward by the pressure spring 26 about the hinge 27, when the OMR card flows in through the inlet 1, the OMR card which flows in advances and pressurizes a spring. The force of (26) is overcome and the branch body 27 is rotated, and in this process, the direction is switched to the sweeping part along one side of the branching body 27 so that it can continue to be conveyed toward the sweeping part. On the other hand, when the postmarked OMR card descends downward, since the branch body 27 blocks the passage to the inlet 1 by the pressure spring 26, the OMR card is formed along the direction of the arrow P2. It becomes possible to discharge to the 2 discharge port 35 side.

The OMR card reading and sweeping device of the present invention is provided with a plurality of sensors for detecting the position of the OMR card according to the work progress. That is, the inlet detection sensor (S1) for detecting the inflow of the OMR card through the inlet (1), the ticket sensor (S2) for detecting the OMR card introduced into the postmark position through the drive system, and the postmarking unit Brand sensor (S3) for detecting whether it is completed or not is provided.

The position information of the OMR card detected from the various sensors of these sensor units is immediately sent to the control unit C, and the control unit C is based on these input information, the drive motor 2 and the solenoid 30. An output signal is sent to to control them.

1, the operation of the OMR card reading and sweeping device according to the present invention will be described.

When the OMR card is inserted into the inlet (1), the incoming detection sensor (S1) detects the incoming OMR card and sends a signal to the control unit (C). The control unit C outputs a control signal to the drive motor 2 based on this signal. Accordingly, the electric power is applied to the driving motor 2 to rotate the driving pulley 3, and the rotational force of the driving pulley 3 is driven to the driven pulley 3 ′ and the driven gear 4 through the driving belt V1. By being transmitted, the first and second feed gears 5 and 29 are rotated in turn. The first to sixth feed pulleys 6 to 11 are rotated through the first transfer belt V2 and the second transfer belt V3 by the rotation of these feed gears 5 and 29, thereby forming an integrally formed article. The first to fifth feed rollers 12 to 16 and the pressure roller 17 start to rotate. Thereby, the OMR card starts to be conveyed in the state interposed between these first to fifth feed rollers 12 to 16 and the first to fifth idle rollers 18 to 22.

At this time, the mark recognition operation is completed while the OMR card passes through the optical recognition section 24, and then, as described above, the OMR card is transferred to the sweeping section. Next, when the ticket detection sensor S2 detects that the OMR card is located in the postmarked portion, the control unit C sends electricity to the solenoid 30 based on the signal from the ticket detection sensor S2. And, as described in FIG. 2, the stamping work is performed by the ticket print head 33, and the stamping completion state is detected by the brand sensor S3 and transmitted to the control unit C.

The control unit C rotates the driving motor 2 forward or reverse on the basis of the signal from the brand sensor S3. Accordingly, the OMR card is first discharged along the direction of the arrow P1. At the time of discharge or reverse rotation, it is possible to discharge to the second discharge port 35 in the direction of the arrow (P2).

Next, with reference to FIG. 3, the locking means for maintaining the combined state of the first upper frame 37 and the second upper frame 39 will be described.

As shown in FIG. 3, the locking means of the present invention slides along the hook 62 formed at the upper end of the first upper frame 37 and the long hole 42a formed at the second upper frame 39. Locking pin 42 is to be, and one end is supported by the stopper 61 and the other end is composed of a torsion spring 41 to press the locking pin 42 toward the hook 62 to maintain a locked state. One end of the torsion spring 41 mounted to rotate about the pin 60 is hung on the stopper 61, and the other end presses the locking pin 42 upwards, so that the locking pin 42 hooks. It is to be kept in engagement with (62).

Therefore, the locking pin 42 is first pushed downward to separate the main body so as to remove the stake or remove it when jam occurs. At this time, the locking pin 42 is to slide the downward downward along the long hole (42a) to overcome the force of the torsion spring 41, thereby releasing the engagement state with the hook (62). As a result, it is possible to rotate the first upper frame 37 on the base frame 36 about the first hinge axis 38, and at the same time, the second upper frame 39 about the second hinge axis 40. ) Can be rotated on the base frame 36, so that the main body can be easily separated as shown in FIG. 3B.

Next, Fig. 4 and Fig. 5 are partial excerpts showing separately the sweeping device employed in the present invention, respectively. In the OMR card reading and sweeping device of the present invention, the ticket printing head 33 is configured to be easily replaced at the time of exchange and maintenance. To this end, the bracket 74 with the ticket printing head 33 is configured to be detachable from the main body by three screws 71 to 73. At this time, when the three screws 71 to 73 are loosened, the return spring 44 and the spring shown in Fig. 5, including the ticket print head 33 and the second pivoting plate 32 fixed to the bracket 74, are released. The shaft 45 can be disassembled from the main body while exiting laterally.

According to the present invention as described above, since the Y-type card moving path is shortened, the copper wire to which the worker moves is shortened, so that the work efficiency is increased, and the entire area is shortened and the area occupied is reduced. In addition, by employing a plurality of gap holding rollers near the feeding portion, the gap between the optical sensor unit for recognizing the mark on the card and the card is precisely maintained, thereby significantly lowering the read rate of the card. In addition, since the two main bodies adopt a two-stage opening and closing method rotatably mounted to the base member around the hinge axis, the main body can be easily attached and detached, and the equity generated during use can be effectively removed, and the jam is removed and maintained. Maintenance work is convenient. In addition, since it is possible to automatically discharge the postmarked ticket, it can be applied to the automated window that is operated unattended and there is an advantage that can reduce the labor cost according to the unmanned operation.
