Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a card-type mechanical lock device, and more particularly to a card-type mechanical lock device that can control entry and exit.

[Conventional technology]

In recent years, card-type mechanical locking devices have come into widespread use because they are convenient to carry as they are in the form of a key or a card (key card), and they do not require an external power source. This card-type mechanical lock device has a key card provided with a recess corresponding to the length of the pin tumbler bottle of the 811 lock main body (hereinafter referred to as the main body), and a card insertion slot (hereinafter referred to as the main body) in the main body.
When the key card is inserted into the insertion slot, the lever handle (or knob) on the main body becomes rotatable, and the latch head is configured to be retracted by this rotation. In addition, other card-type mechanical lock devices are known, in which the pin tumbler bottle is a magnet magnetized in a predetermined direction, and a magnetic type is known in which a key card has a corresponding magnet embedded in it. . In short, these conventional card-type mechanical lock devices check the data part of the key card inserted into the insertion slot of the main body and the data part of the main body, and if the data in both data parts do not match, the main body is configured so that it can be unlocked.

[Problem to be solved by the invention]

However, in the above-mentioned conventional device, locking of the main body,
The unlocking operation was performed entirely mechanically, and the operation was not recorded, so there was a drawback that only access could be controlled. For example, if the main unit is installed on the door of a room that requires high security, such as a safe, and there are multiple staff members who can enter the room, it is important to know when someone can unlock the main unit and enter the room. One of the drawbacks was that it couldn't record anything at all. In this way, the conventional main unit does not require an external @ source, so although it has the great advantage of being inexpensive and easy to install, it has the disadvantage of not being able to control entry and exit as mentioned above, so it is expensive. This has the problem that it cannot be installed on the door of a club room where security is desired. The inventors of the present invention focused on the fact that the key is in the form of a card, and as a result of intensive research, they completed a card-type mechanical lock device that can record entry and exit. That is, an object of the present invention is to provide a card-type mechanical lock device that can record entry and exit.

[Means to solve the problem]

In order to achieve the above object, the device of the present invention verifies the data section of the key card inserted into the insertion slot of the main body and the data section of the main body, and when the data of both data sections match, the main body In a card-type mechanical lock device that can be unlocked, a reading means reads personal identification data from the inserted key card, and when the read personal identification data is stored in a memory, it is possible to check both data parts. The invention is characterized in that it has a shutter means.

[Operation 1] In the above configuration, when the personal identification data of the key card inserted into the insertion slot is stored in the memory, the shutter means is opened. Therefore, the data section of the key card and the data section of the main body can be verified, and once the verification is performed, the main body can be unlocked. [Embodiment 1] Hereinafter, one embodiment of the present invention will be described based on the drawings. FIG. 1 is a perspective view of an embodiment of the apparatus, showing an example in which the main body 1 is attached to a hinged door a. Similar to the well-known card-type mechanical lock device, when a predetermined key card C is inserted into the insertion slot 2, the main body 1 becomes rotatable in the direction of the arrow.
When the latch head 4 is rotated, the latch head 4 is moved backward and the door a is opened. FIG. 2 is a perspective view of the key card C. On the upper surface of the #i section in the insertion direction (direction of the arrow), there is a data section 5 formed of a combination of a plurality of types of recesses, similar to the well-known key card.
is provided, and an ID data section 6 is also provided parallel to the insertion direction at the center of the top surface. This ID data section 6 is prerecorded in the form of personal identification data or magnetic data. Note that 7 in the figure is an electric fence on which the name of the person holding the key card C is written. FIG. 3 is a sectional view taken along line I-1 in FIG. 1, showing the internal structure of the main body 1. That is, the main body 1 has its casing 10 fixed by screws from the inside of the stud mounting hole a' of the door a (room rPJ>), and the gauging 10 has a lever handle 3 and an insertion slot 2 on the front side. A cover 11 having an opening is provided.The lock mechanism 12 includes a data section 13 consisting of a pin tumbler of the main body 1 and a data section 5 of a key card C inserted into the insertion slot 2.
When the latch head 4 is checked, the latch head 4 can be moved backward by rotating the lever handle 3. On the other hand, the main body 1 is forced by the handle 14 provided inside.
In other words, the door can be unlocked without inserting the key card C.
The locking mechanism is similar to that of a well-known card-type mechanical lock. The magnetic head H corresponds to the reading means of the present invention, and is inserted into the insertion slot 2111 of the card passage 2a so that it can read the magnetic data of the ID child data 6 of the key card C inserted into the insertion slot 2. ! ! It is located at I. Shutter 1 consisting of solenoid S and its plunger
5 is provided to block or open the card passage 2a between the magnetic head H and the data section 13. Note that the shutter 15 always blocks the card passage 2a as shown in the figure with a spring (not shown), and when the solenoid is turned on, moves upward for several seconds (2 to 3 seconds) to remove the key card C from the card. Data section 13 in passage 2a
It is configured so that it can be inserted up to A chamber 16 is provided at the bottom of the casing 10, in which a battery E such as a lithium battery and a printed circuit board P that uses the battery as a power source and incorporates electrical components described below are installed.
or stored. FIG. 4 is a block diagram showing the electrical configuration of the embodiment device, in which the portion surrounded by the dashed line - is incorporated into the printed circuit board P, and includes the read driver 16 of the magnetic head H described above and the solenoid S. solenoid driver 17
The battery E is connected to a terminal port 18 provided in the casing 10 for connecting external devices. The printed circuit board P is mainly composed of a so-called microcomputer, and a control unit (CPU) 20 has a memory 2.
The control unit 20 is connected to the read driver 16 .1 via the I10 unit 22 . Solenoid driver 17. #A port 18 is connected. The memory 21 is
a ROM in which system program memory is stored;
It is composed of a RAM capable of storing a predetermined capacity of ID data read by the magnetic head H. Next, the operation of the device of this embodiment will be explained. Now, when the door a is closed and the key card C is inserted into the insertion slot 2, the magnetic data of the ID child data 6 is read by the magnetic head H. The read signal is passed through the read driver 16, 110 unit 22 to the memory 2.
1. When this reading and storing operation is completed, the control unit 20 drives the solenoid driver 17 to turn on the solenoid S, and closes the shutter 15 for a predetermined period of time (2 to 3 seconds).
Lift it upward to open the card slot 1i 182a. Then, while the shutter 15 is being lifted, the key card C is in the li! of the card passage 2a! The data section 5 of the key card C and the data section 13 of the main body 1 are checked. As a result of checking with both data sections 5 and 13, if the checks match, the main body 1 becomes unlocked, and therefore, when the lever handle 3 is rotated, the latch head 4 retreats to open the door a. I can do it. The inserted key card C is removed by the person entering the room when the door a is opened. Also, when leaving the room,
The handle 14 is rotated to move the latch head 4 backward and open the door. In the RAM of the memory 21, in addition to the ID data of the inserted key card C, an internal timer of the control unit 20 stores the insertion time of the key card C. This stored content can be retrieved by connecting an external device to the terminal port 18. A well-known personal computer equipped with an output device such as a display screen or a printer is used as the external device, and the past entry status can be checked periodically or when an abnormal situation occurs in the room where door a is installed. When it becomes necessary to investigate, external equipment can be connected to the terminal port 18 and the contents stored in the memory 21 can be output. Note that the memory in the RAM of the memory 21 is cleared after it has been output, or if the management system is such that it is not output periodically, the RAM of the memory 21 is set as FILO memory, and the data is stored in a range that goes back a certain period of time. It is convenient to store only the ID data within. According to the device of this embodiment, unless the ID data of the key card C inserted into the insertion slot 2 is read and stored, the shutter 15 will not move upward and the key card C cannot be inserted. Therefore, the main body 1 will be unlocked. If you do, your entry will be recorded. The recorded data can then be retrieved by external equipment as needed. In addition, the drive current of the solenoid S is extremely small, unlike that of the solenoid of a well-known electric lock, and the memory 2
1. The holding current is also extremely small, so the battery life can be maintained for a long time. 4. According to the calculations made by the present inventors, the device of the embodiment can be operated without maintenance for more than 3 years using a commercially available lithium battery. Note that if it is necessary to store the information in the memory 21 even when leaving the room, an insertion slot 2 having a card passage equipped with the above-mentioned magnetic head H and shutter 15 may be provided on the room side as well. In addition, ID data is stored in advance in the memory 21,
If this ID data is checked against the ID data of the inserted key card C, and if they do not match, the solenoid S will not be activated even after the ID data has been read and stored. It can be a locking device. Furthermore, when both the data sections 5 and 13 described above use magnets, the ID data section 6 may be formed not from magnetic data but from a bar code or the like that can be read optically.
Reading errors can be prevented. Effects of the Invention According to the device of the present invention, the shutter means is not opened unless the personal identification data of the key card inserted into the insertion slot is read and stored. Whenever the data section of the key card is checked and the key card is in an unlocked state, the personal identification data of the key card is stored in the memory, and the state of use of the key card is recorded. Therefore, the card-type machine locking device of the present invention enables room entry/exit control.
