Description

[Detailed Description of the Invention] This invention relates to a card holding mechanism of a locking device that uses a card to unlock an input door of an input safe, an entrance door for people, etc.

2. Description of the Related Art There is a locking device that uses a card to unlock and lock an input door of a deposit box, an entrance door for people, and the like. This locking device can be unlocked when the code stored on the card matches the code entered by the user by pressing a button, etc., and the lock can be unlocked if the card is lost or stolen. Even if the card is unlocked, only a person who knows the code of the card can unlock it, which is preferable in terms of security.
However, conventional locking devices have the following problems. In other words, with a lock that uses a key, you cannot remove the key from the lock unless you open the deposit box door, entrance door, etc., and then close the door after finishing your business, which can lead to forgetting to lock the door. However, with cards that use cards, the card can be pulled out of the card slot without locking the door, making it easy to forget to lock the door.

In order to solve this problem, a through hole is formed in the card, and a lock pin is inserted into the through hole to prevent the card from being pulled out when the card is inserted, and the lock pin is locked when the door is closed. The applicant has already proposed a locking device using a card having a card holding mechanism that allows the card to be removed from a hole in the card. However, this card holding mechanism requires a through hole to be provided in the card.

In view of the above points, this invention makes it possible to use a card similar to a conventional card without the need to form a through hole in the card, and provides a card holding mechanism for a locking device that uses a card with a simple structure. This invention was created with a purpose in mind, and for this purpose, this invention consists of a card having a convex portion, a detection device for detecting the insertion of the card, and a card holder having a surface that intersects with the card surface of the inserted card. a slit having a gap having a vertical length slightly larger than the thickness of the card inserted into the card holding part, and a card inserted into the card holder so that the inserted card is positioned within the slit. The card holding member is movable parallel to the plane, and the movement of the card holding member in the card holding direction is linked to the card detection of the detection device, so that when the card is inserted, the convex part of the card is moved further into the device than the slit. This feature is characterized in that the card is positioned at the top of the card to prevent the card from being removed until after the operation is completed.

The details of this invention will be explained below based on the preferred embodiment shown in the drawings. One embodiment is shown in FIGS. 1-4, and another embodiment is shown in FIGS. 5-7.

In the figure, reference numeral 1 denotes a card, which is inserted through the card insertion slot to unlock and lock the lock.Protrusions 2 are provided at appropriate positions on the card 1. The convex portion 2 may be in the shape of numbers, letters, etc., as shown in FIGS. 8 and 9, or may be in any other arbitrary shape. In particular, currently, cash cards from banks, etc. usually have the store number, etc. of the person in charge engraved on the surface of the card by press molding, and the above-mentioned protrusion 2 can be used as this store number, etc. . The point is that it only needs to protrude from the surface of card 1.

In the figure, reference numeral 3 denotes a micro switch, and its detection terminal 4 is positioned within the advancing area of the inserted card 1 so as to detect that the card 1 has been inserted and close the switch. By closing this micro switch 3,
The rotary solenoid 5 is configured to rotate. In the figure, reference numeral 25 denotes a card stopper which allows the inserted card to come into contact with its tip and be positioned at the innermost position, and is provided at a position where the micro switch 3 can be opened and closed sufficiently.

In the embodiment shown in FIGS. 1 to 4, the rotation of the rotary solenoid 5 is transmitted to the card holding member 7 via the connecting member 6. In the embodiment shown in FIGS. The connecting member 6 is
As shown in FIG. 1, it has an approximately L-shaped projected shape, and has one end connected to a pin 8 protruding from the rotary solenoid 5, and the other end a long hole 9 formed in the card holding member 7.
Protruding the engagement pin 10 that is loosely inserted into the
A substantially central portion is rotatably supported by a shaft 11 on a stationary portion of the device. The card holding member 7 is inserted into a through hole 13 formed in the housing 12 of the device so as to be able to move in parallel.

In the embodiment shown in FIGS. 5 to 7, the rotation of the rotary solenoid 5 is transmitted to the card holding member 7 by connecting a pin 8 protruding from the rotary solenoid 5 to the card holding member 7. . One end of the card holding member 7 is pivotally supported 14 on the housing 12 of the device.

The card holding member 7 is provided with a card holding part 15, and this card holding part 15 has a surface that intersects the inserted card 1, and in particular, in this embodiment, it intersects at right angles. Then, the card holding portion 15 is inserted into the card holding portion 15 from one side end thereof.
A slit 16 with a gap slightly larger than the thickness of the card 1 to be inserted is formed horizontally up to approximately 2/3 of the width of the card 1. Further, the gap between the slits 16 must be smaller than the thickness of the card 1 including the protrusion 2 provided on the card 1. The slit 16 does not need to be approximately 2/3 of the width of the card holding portion 15 as described above, and it is sufficient if the slit 16 can fulfill the function described later. 17 in the figure is a card receiving part formed by widening the open end of the slit 16,
If the notch is cut diagonally as shown, it is desirable for the slit 16 to receive the card 1 in the operation described later. In this embodiment, the card holder 15 is provided so as to be perpendicular to the inserted card 1, but the card holder 15 may not intersect at a right angle but may intersect at another angle. In this case, the gap between the slits 16 is as follows.
The length of the gap in the direction perpendicular to card 1 is
Any thickness may be used as long as it is larger than the thickness of the card 1 and smaller than the thickness of the card 1 including the convex portion 2. In other words, the card holding portion 15 is positioned closer to the insertion slot than the convex portion 2 formed on the card 1 when the card 1 is inserted to the innermost part.
The convex portion 2 formed in the card holding portion 15 is located deeper in the device than the card holding portion 15.

In the figure, reference numeral 18 denotes a holding arm, which is rotatably supported on a stationary part of the device, and its rotation is performed by coming into contact with the side end surface of the card 1 inserted through the insertion slot.
Therefore, a part of the card is bent, and the card 1 is placed in this bent part.
The side end surfaces of the two are in contact with each other. A restoring force is applied to the holding arm 18 by a spring 19 so that the holding arm 18 rotates in a direction in which the holding arm 18 always contacts the card 1.
It holds the inserted card 1 and positions the card 1 at an appropriate position.

In the figure, reference numeral 21 denotes a card reading device that reads the code code stored in the inserted card 1 or compares it with the code code input by the user by pressing a button (not shown). This unlocks the lock so that the door can be opened. It is also possible to operate the rotary solenoid 5 by the cooperation of the card reading device 21 and the microswitch 3, and this is desirable in terms of safety. It is also possible to have only the card reading device 21 operate the rotary solenoid 5 without providing the micro switch 3, and in this case, the card reading device 21 also functions as a device for detecting a card. The code code of the card 1 read by the card reading device 21 is stored in the magnetic stripe 22 of the card 1.

The circuit is configured so that the rotary solenoid 5 operated as described above returns to its original position by the opening/closing operation of the slot door, etc., so that the slot door etc. have a switch function. Alternatively, the rotary solenoid 5 may be returned to its original position by pressing a button after the user finishes his errand and closes the slot door. In addition,
In FIGS. 1 and 6, the position where the rotary solenoid 5 is located when the card holding member 7 is in the position shown by the solid line is the original position. Further, the direction of movement from the position shown by the solid line to the position shown by the dashed-dotted line is the card holding direction.

Furthermore, as shown in FIGS. 5 to 7, a stopper 23 is provided on the card holding member 7, so that when the card holding member 7 rotates due to the operation of the rotary solenoid 5 when the card is inserted, it comes into contact with the stopper 23. It is desirable to provide the housing 12 with a cushioning member 24 made of rubber or the like.

When the card 1 is fully inserted, the detection terminal 4 of the microswitch 3 is pushed against the leading edge of the card 1, and the microswitch 3 is closed. The rotary solenoid 5 is actuated by the closing of the microswitch 3 and the operation of the card reader 21 when the card 1 is a legitimate one. That is, in FIG. 1, it rotates clockwise in the figure, and in FIG. 6, it rotates counterclockwise in the figure. Due to the rotation of the rotary solenoid 5, the card holding member 7
However, in FIG. 1, it moves in parallel to the position shown by the dashed line, and in FIG. 6, it rotates about the shaft 14 to the position shown by the dashed dot line. Due to this operation of the card holding member 7, the inserted card 1 is partially inserted into the slit 16 formed in the card holding part 15.
It will be located inside. At this time, slit 1
The position 6 is the part of the card 1 where the convex part 2 is not formed, and the convex part 2 is located deeper than the slit 16, so even if you try to pull out the card 1 from the insertion slot, the convex part of the card 1 Since the portion 2 engages with the card holding portion 15, the card 1 cannot be pulled out.

When the user finishes his errands and closes the slot door, etc., the rotary solenoid 5 rotates back to its original position, and the card holding member 7 also returns to the position shown by the solid line, making it possible to pull out the card 1.

Further, when the card holding member 7 is in the position where it waits for the card 1 to be inserted as in this embodiment, that is, when it is in the position shown by the solid line in the figure, the card receiving portion 17 of the slit 16 is inserted. card 1
By positioning the card 1 at the side end of the card 1, the slit 16 can smoothly receive the card 1 through the operation of the card holding member 7 described above.

As mentioned above, the card holding mechanism of the present invention has a slit formed in the card holding plate that is activated by insertion of a card, the gap being slightly larger than the thickness of the card, and the card is positioned within the slit. Since the protrusion formed on the card is positioned deeper into the device than the slit, there is no need to provide a through hole in the card, and the same card as the previous card can be used, resulting in an effective card holding mechanism. I was able to do this. Further, the structure can be made simple by providing a card holding member with a slit formed therein, and therefore it has the effect of being able to be provided at low cost.
