Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a card insertion mechanism for a card processing device that reduces the number of parts and improves assembly workability and reliability.

[Conventional technology]

Generally, the card insertion mechanism of a card processing device is
The shutter mechanism prevents further insertion of the card inserted into the card entry passage from the card insertion slot, thereby preventing unauthorized use of the pseudo card, and after the card is determined to be a genuine card by the card detection means. The card is taken in by pushing the card down and removing it from the shutter mechanism. In addition, in a card processing device in which a card insertion slot and a card return slot are separately provided by connecting the back ends of the card intake passage and the card return passage to the front end of the card processing conveyance passage, the card intake passage and the card return passage are A selector for switching between these two passages is disposed between the shutter mechanism and the shutter mechanism, and normally the selector blocks a portion of the card intake passage further from the shutter mechanism to prevent communication between the card intake passage and the card processing conveyance passage; When the card is taken in, by rotating the selector in conjunction with the shutter mechanism, the card taking passage is opened and communication between the card return passage and the card processing conveyance path is blocked, and the card is not placed in the card processing conveyance path. After being imported, the selector is returned to its original state. This is said to be effective in preventing the card from being erroneously returned to the card receiving passage when returning the card.

[Problem that the invention attempts to solve]

However, as mentioned above, conventional card insertion mechanisms are equipped with a shutter mechanism and a selector, and are configured to be operated by separate drive devices, which increases the number of parts and makes it difficult to assemble them into a narrow space. The process was complicated and difficult to assemble, which caused an increase in costs, and the weight of the device itself increased.Furthermore, the increased number of parts caused many inconveniences, such as making it more likely to break down and lack reliability.

[Means for solving problems]

The card insertion mechanism of the card processing device according to the present invention was made to solve the above-mentioned problems, and includes a card intake passage that is continuous with the card insertion slot,
A rotating lever disposed between the card return passageway that is continuous with the card return slot, a drive device that rotates this rotating lever by a predetermined angle when a card is taken in, and a drive device that rotates the rotating lever by a predetermined angle when the card is taken in. and a driven side take-in roller rotatably disposed at a position such that the rotary lever is normally located in the card take-in passage, thereby blocking the card take-in passage and removing the card. a shutter part that prevents further entry of the card and opens a card take-in passage when the card is taken in; and a shutter part that extends to the intersection of the card take-in passage and the card return passage and normally serves as the card take-in passage. integrally includes a passage switching section that blocks communication with the card processing conveyance path, opens a card intake passage when a card is taken in, and blocks communication between the card return passage and the card processing conveyance path; The take-in roller is brought into pressure contact with the drive-side take-in roller as the rotary lever rotates during card take-in.

[Effect]

In this invention, the rotary lever integrates the shutter part and the passage switching part, and has the functions of both the shutter mechanism and the selector, so the number of parts can be reduced, the assembly workability and reliability are improved, and it is small and lightweight. make it possible to The rotating lever also serves as a holding member for the driven-side intake roller.

Next, the card processing device 1 configured as described above will be described.
Explain the operation.

FIG. 1 shows a state in which the card 26 is inserted into the card insertion slot 2. In this state, the insertion end of the card 26 comes into contact with the stopper portion 44 of the rotating lever 23, so that the card 26 can not enter further. When a detector (not shown) detects the insertion of the card 26, a detection signal is sent to the control circuit, and the control circuit determines whether or not the card 26 is a legitimate card. Issue processing instructions. Then, the solenoid 29 is energized by energization, causing the movable iron core 48 to protrude, thereby rotating the rotating lever 23 clockwise against the spring 28, thereby causing the slit 43 to move into the card receiving passage. 4, and the driven-side take-in roller 18 presses the card 26 against the drive-side take-in roller 17. FIG. 4 shows this state.

The drive motor 12 rotates clockwise, and its driving force is transmitted to the deceleration pulley 56 via the drive belt 58 to be decelerated, and then transmitted to the conveyance pulley 52b on the same axis as the pulley 56. Transport pulley 52b
is rotated by the driven belt 5 via the conveyor belt 54.
5. For this reason, the drive side intake roller 1
7 rotates counterclockwise, and the card 2 is taken in by the conveyance force.
6 is taken into the interior along the card take-in path 4 , and then held between the conveyor belt 54 and the driven belt 55 and conveyed to the card processing conveyance path 5 .

When the card 26 reaches the magnetic head 13, the information reading process is confirmed. This is card 26
This is carried out while 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 26 has passed over the path switching parts 35A and 35B of the rotary lever 23, the solenoid 29 is energized by a control command from the control circuit. Then, the rotation lever 23 is restored to its original state by the force of the spring 28. As a result, the card receiving passage 4 is connected to the shutter portion 4 of the rotary lever 23.
4 and path switching sections 35A and 35B, the card processing conveyance path 5 and card return path 6 are brought into communication.

When the necessary processing operations such as reading information are completed,
The card 26 is returned to the card return slot 3 through the card return passage 6. At this time, the card 26 will be conveyed in the opposite direction to that at the time of taking in, but this is made possible by rotating the drive motor 12 in the opposite direction.

[Effect of idea]

As described above, the card insertion mechanism of the card processing device according to the present invention has a rotary lever disposed between the card take-in passage and the card return passage, and the rotary lever normally blocks the card take-in passage. Since the shutter section and the path switching section for switching the communication between the card take-in path and the card return path with respect to the card processing conveyance path are integrally provided, and a roller is provided on the driven side of this lever, the rotary lever can It functions as a shutter mechanism, selector, and roller holding member, and the number of parts can be reduced. In addition, since only one drive unit is required, the structure is simplified, improving assembly workability, making it possible to reduce size, weight, and cost.Furthermore, fewer parts means fewer breakdowns and improves the reliability of the equipment itself. The practical effects are very large.
