Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a card transport mechanism of a card reader. More specifically, the present invention relates to a card transport mechanism of a card reader of a type in which a card is transported while being locked by a locking member.

[0002]

2. Description of the Related Art As a transport mechanism of a card which is an information recording medium, there is a type of a transport mechanism in which a card is locked and transported while being placed on a card mounting table (Japanese Patent Publication No. Hei 5-84588).
issue). In this type of card transport mechanism, the card locking member is moved by utilizing the movement of the card mounting table to lock the card on the card mounting table. That is, a tapered surface is provided at a predetermined position on the movement locus of the card mounting table, and the card locking member is slid with respect to the tapered surface to move the card locking member in a direction orthogonal to the moving direction of the card mounting table. The card is sandwiched between the card mounting table.

[0003]

However, the above-described card transport mechanism has a structure in which the card mounting member starts moving and the card locking member gradually starts to clamp the card while sliding on the tapered surface. It is necessary to convey the card by a take-in roller or the like until the card is firmly clamped so that the relative position between the card mounting table and the card does not shift. In practice, it is difficult to completely match the moving speed of the card mounting table with the feed speed of the rollers. If these speeds are significantly different, there is a possibility that the take-in roller may be scraped or the card may come off.

In the above-described card transport mechanism, the card is pinched by using the tapered surface, so that the card cannot be released at a position other than the position where the tapered surface is provided. At the position where the tapered surface is provided, the holding of the card is always released. For this reason, for example, it has not been possible to branch the transport path of the card in the middle and switch the transport path according to the card. In other words, if the card is to be transported through the branch position as it is, the card must be locked on the card mounting table and transported as it is, while if the transport path is switched at the branch position, the card must be transferred to the card mounting table. However, the above-described card transport mechanism cannot maintain or release the locking of the card in the middle of the card transport path.

According to the present invention, it is possible to prevent an adverse effect due to a mismatch between the moving speed of the card mounting table and the feed speed of the roller, and to arbitrarily release the locking of the card at an arbitrary position in the card transport path. An object of the present invention is to provide a card transport mechanism of a card reader.

[0006]

In order to achieve the above object, according to the present invention, a rear end face of a card in a card running direction is brought into contact with a first card locking member which moves in the card running direction. In the card transport mechanism of the card reader configured to transport the card by the first card locking member, the first card locking member is attached to the rear end surface of the card by the carriage movable in the card traveling direction. The first card engaging member is provided with a traveling driving member for traveling and moving the card, the first card engaging member being attached so as to be movable between a position at which the card can contact and a position at which the card does not contact. The stop member is connected so that the position of the stop member changes based on the moving direction of the traveling drive member, and when traveling to one side of the card, the first card locking member is brought into contact with the rear end face of the card by the travel drive member. Moving the carriage with the possible locations are those configured to convey the card.

Accordingly, when the traveling drive member moves in the direction of transporting the card to one side, the first card locking member moves to a position where it can contact the rear end face of the card. That is, the first card locking member locks the card, and the carriage can be moved by the traveling drive member. When the traveling drive member further moves in this state, the carriage is transported, and the first card locking member attached to the carriage transports the card in a locked state. After this,
When the traveling drive member moves in the reverse direction, the first card locking member moves to a position where it does not contact the card. That is, the first
The card lock by the card lock member is released.

According to a second aspect of the present invention, there is provided a card transport mechanism for a card reader, wherein the second card holder is capable of moving the carriage between a position where it can contact the front end surface of the card and a position where it does not contact the card. The stop member is connected by the traveling drive member such that the position of the second card engaging member changes based on the moving direction of the traveling drive member, and the first card engaging member can contact the end face of the card. When the card is in the correct position, the second card locking member is connected so as not to abut on the card, and when the card is running in the reverse direction, the second card locking member is brought into contact with the front end face of the card. The card is conveyed by moving the carriage and setting the contactable position.

Therefore, when the traveling drive member moves in the reverse direction, the second card locking member moves to a position where it can contact the front end face of the card, and the first card locking member does not contact the card. Move to position. That is, while the card is unlocked by the first card locking member, the card is locked by the second card locking member, and the carriage can be moved in the reverse direction by the traveling drive member. In this state, when the traveling drive member further moves in the reverse direction, the carriage is transported in the reverse direction, and the second card locking member attached to the carriage transports the card in the reverse direction with the card locked.

In the card transport mechanism of the card reader according to the third aspect, when inserting a card, the first card locking member located on the card insertion port side is set at a position where it does not come into contact with the card by the traveling drive member. ing. Therefore, when the card is inserted from the card insertion slot, interference between the card and the first card locking member can be avoided.

Further, in the card transport mechanism of the card reader according to the present invention, the first and second card locking members are rotatably attached to the carriage, and the traveling driving member is the first and second cards. It is a string-shaped member provided with an engagement portion so that the locking member can be controlled from both directions. Therefore, when the string-shaped member, which is the traveling drive member, moves, the engaging portion controls the positions of the first and second card locking members and locks the card by either of them.

The card reference side 12 is provided over substantially the entire length of the card transport path. On the other hand, the shift plate 13 is formed to have substantially the same length as the carriage 3, is rotatably attached to the side surface of the carriage 3, and presses the card 1 against the card reference side 12 by the urging force of a coil spring (not shown). The carriage 3 is disposed below the lower guide 11, and is guided and slid in the transport direction of the card 1 by two shafts 14 fixed to the card reader main body.

When the card 1 is inserted, the first card locking member 2 located on the card insertion slot side (the left front side in FIG. 1) is set to the retreat position D by the traveling drive member 4.

A timing belt 15 is stretched by fixed pulleys 16 and 17 and idler pulleys 18 and 19 on the left side in FIG. 1 of the card transport path. A gear 20 integrally formed with the pulley 16 is attached to a motor 21. Gear 22
And the drive transmission is possible.

Next, the operation of the card transport mechanism will be described.

When the card 1 is not taken into the card reader, the carriage 3 is located at the card insertion slot side. At this position, the carriage 3 is fixed to the card reader body by a lock pin (not shown). I have. Therefore, movement of the carriage 3 due to vibration during transportation or operation is prevented. From this state, when the card 1 is taken into the card reader, the lock pin is released by the solenoid (not shown).

When the card 1 is inserted in the direction of arrow C in FIG.
Starts. The driving force of the motor 21 is gear 22 → gear 20
→ fixed pulley 16 → transmitted to the timing belt 15,
This timing belt 15 rotates counterclockwise in FIG. As a result, the inserted card 1 is fixed to the fixed pulley 16.
It is captured by being sandwiched between the upper timing belt 15 and the pad set 23.

When a sensor (not shown) detects that the card 1 has been taken up to a predetermined position, that is, a position facing the carriage 3, the motor 9 starts. The driving force of the motor 9 is transmitted to the traveling drive member 4 via the pulley 7. When the traveling drive member 4 rotates clockwise in FIG. 1 (direction A in FIG. 3), the engaging portion 6 provided on the card insertion port side of the first card locking member 2 engages the first card engaging member. The first card locking member 2 is erected by engaging with the stopping member 2. That is, the first card locking member 2 is moved to the card locking position D where the first card locking member 2 hits the convex portion 3a of the carriage 3.

At this time, the second card locking member 5 is tilted down as shown in FIG. 3 by an engaging portion 6 provided on the card insertion opening side of the second card locking member 5, and Retreat downward. That is, it moves to the retreat position G. When the motor 9 further drives the traveling driving member 4 in this state, the first card locking member 2 hits the convex portion 3a of the carriage 3 and conveys the card 1 and the carriage 3 in the A direction.

In this card transport mechanism, the traveling drive member 4
The card 1 can be locked or unlocked by simply rotating the card locking members 2 and 5 at any position within the sliding range of the carriage 3 by simply changing the driving direction of the card to the A or B direction. can do. Therefore, when a branch path is provided in the middle of the card transport path, the card 1 can be unlocked at the branch position only when the card 1 is transported to the branch path, and the card 1 is not transported to the branch path. In this case, the card 1 can be passed through the branch position in a locked state. That is, in the case where the card transport path is branched by adding a separate transport system, or in the case where a card waste ticket holder is provided, it is possible to branch at an arbitrary position. Further, when the card is forcibly removed manually, it is possible to remove the card in an arbitrary position in either the front or rear direction.

In this card transport mechanism, when the carriage 3 is moved, the carriage 3 is moved only after the first card locking member 2 that does not lock the card 1 in the card loading state locks the card. In addition, the displacement of the relative position between the carriage 3 and the card 1 is suppressed, and the problem that the mechanism for locking the card 1 comes off does not occur.

When the carriage 3 is driven, the motor 9 rises with a small inertia when the motor 9 rises, and the carriage 3 is conveyed after the motor 9 rises. Becomes shorter.

The above-described embodiment is an example of a preferred embodiment of the present invention, but is not limited thereto, and various modifications can be made without departing from the gist of the present invention. For example, a case has been described in which the present invention is applied to a card reader (writer) having a magnetic head 24. However, an IC card reader (writer) that handles an IC card, a magnetic / IC
Needless to say, the present invention can be applied to a card reader (writer) for handling cards.
