Description

[Detailed Description of the Invention] This invention is a card-enabled device suitable for the entrance/exit door of a room in which an automatic cash deposit machine, an automatic cash withdrawal machine, etc. are installed in a financial institution such as a bank, or a slot room of a night safe. The present invention relates to a new locking device that can be unlocked and unlocked.

The current situation is that the entrance/exit doors of rooms with automatic cash deposit machines, automatic cash withdrawal machines, etc., or the slot room of night safes are left open for users and are not locked. . Therefore, non-users, that is, those who do not have a contractual relationship with the financial institution, can freely enter and exit the room, which is not desirable in terms of safety. In addition, stores that are open during hours and days when financial institutions are not handling cash transactions,
I would like to receive and pay cash on such days and times, but
For safety reasons such as those mentioned above, automatic teller machines,
It was not possible to use automatic cash withdrawal machines.

For this reason, the entrance/exit doors of rooms with automatic cash deposit machines, automatic cash withdrawal machines, and the slot room of night safes are designed to be unlockable, and the key is entrusted to the policyholder in advance for unlocking. It might be possible to pass it on.
However, it is difficult to hand over the keys to all of the policyholders when there are many policyholders, and therefore it is difficult to provide unlockable entrance/exit doors as described above. It was hot.

The present invention focuses on the above points and the current situation where cards are used in automatic deposit machines, etc., and makes it possible to unlock and lock the entrance/exit door of a room where an automatic deposit machine, etc. is installed using a card. Preferably, a locking device using a card is provided so that a card used in an automatic teller machine, etc. can be used in combination with a card for unlocking the entrance/exit door of a room in which the automatic teller machine, etc. is installed. Although this was done for the purpose of providing, it does not necessarily have to be used together. In addition, in the case of a card-based unlocking device, a card reading device is installed and an electrical system is required, which has the disadvantage that unlocking cannot be performed in the event of a power outage. Another object of the present invention is to provide a locking device using a card that can be unlocked.

For this purpose, the present invention provides a card having a notch formed from one edge, a card stopper that fits into the notch of the card when the card is inserted, a card reading device for confirming the correctness of the card, and a card stopper that fits into the notch of the card when the card is inserted. A lever lock member that rotates to an unlocked position in a rotational motion by the attracting action of a disposed solenoid, and a device that engages and disengages from the lever lock member by the rotational motion of the lever lock member.The device is rotatably supported on a stationary part. It consists of a lever, a latch that is rotatable and is applied with a spring elastic force to engage and disengage from the bar of the lock, and normally returns automatically to the locked position, and a switch that opens and closes by rotating the latch. The rotation of the lever and the rotation of the latch are linked, and the attracting action of the solenoid is released by opening or closing the switch, which is opened or closed by the rotation of the latch, and the lever lock member is moved from the unlocked position to the original position. The lock is a night-latch type automatic lock, and the card is provided with a notch in which a part of the side end is cut out. A starting arm is pivoted on a stationary part of the device so that the formed side end contacts the uncut side edge and can be rotated by inserting or pulling out a card, and one end is removably connected to the starting arm and the other end is rotatably supported by the device. A locking plate is rotatably supported at one end of the exchange plate (to be described later) so as to be rotatable with respect to the exchange plate, and slides in conjunction with the rotation of the start arm when engaged with the start arm, and a distal end edge of the inserted card. a locking plate locking member pivotally supported on an immovable part of the device, which is engaged with and can be rotated when a card is inserted or pulled out, and which prevents or allows sliding of the locking plate by said rotation, and said locking plate; The opposite end of the lever lock member is rotatably supported, and the opposite end thereof is connected to support the rotation of the lever lock member, and the substantially central portion is rotatably supported to the stationary part of the device, and the lever lock member is rotatably supported by the lever. an exchange plate to which a forcible rotational force is applied in a direction that allows rotation in a direction to prevent the rotation of the lever; an operation plate rotatably supported on a stationary part of the device, which releases the engagement with the lever lock member by rotation of the lever when engaged, and applies a forced rotational force in the direction of engagement with the lever lock member; , a connecting member connecting the locking plate and the operation plate, which rotate the operation plate by the rotation of the locking plate, the card stopper, the card reading device, a latch, and opening/closing by the rotation of the latch; The rotation of the lever and the rotation of the latch are linked, and when the switch is opened or closed by the rotation of the latch, the attracting action of the solenoid is released and the lever lock member is opened or closed. The lock is rotated to return from the unlocked position to the original position, the locking plate and the starting arm are electrically engaged and engaged when no electricity is applied, and the lock is of a night latch type. It is characterized by an automatic locking mechanism, and furthermore, without providing a connecting member that connects the locking plate and the operation plate,
Another feature is that the operating plate is rotated electrically, and when not energized, the operating plate is engaged with the lever lock member by a forced rotational force applied to the operating plate.

The details of the locking device of the present invention will be explained below based on the preferred embodiment shown in the drawings.

1 in the figure is a card for unlocking the locking device of the present invention, which has been entrusted to the user in advance, and the card is shown in the insertion slot 2.
It is inserted from the inside to unlock the door. card 1
A notch 3 is formed from one edge toward the center of the card 1. In the figure, reference numeral 4 denotes a card stop, which is fixed to the device so as to fit into the notch 3 when the card 1 is inserted.Of course, it will not fit unless the card 1 has a regular notch 3. Further, the card 1 has an encryption code stored in advance.

Reference numeral 6 in the figure denotes a lever lock member, which is rotatably supported by a shaft 7 on a stationary part of the device, and in FIGS. 1 and 3, rotation in the clockwise direction in the figure allows the entrance/exit door 5 to open. It is something. In this embodiment, the solenoid 8 is responsible for rotating the entrance/exit door 5 in a direction that allows the door to be opened. That is, the card reading device 9 operates to confirm whether or not the code code stored in the inserted card 1 matches the code code entered by the user by pressing a button (not shown). , the solenoid 8 is actuated to attract the lever lock member 6. Further, in this embodiment, when the solenoid 8 is not operating, the lever lock member 6 is moved to a position away from the solenoid 8 by the elastic force of the spring 10 so that it does not rotate in the direction that allows the door 5 to open. That is, it is positioned at the original position to prevent the entrance/exit door 5 from opening.

In the figure, reference numeral 12 denotes a lever that engages and disengages from the lever lock member 6, and is designed to rotate in conjunction with the rotation of a latch, which will be described later. When the lever 12 is in the position where it is engaged with the lever lock member 6, the lever 12 is prevented from rotating, and therefore the latch connected to the lever 12 is also prevented from rotating. Entrance/exit door 5 cannot be opened.

In the figure, reference numeral 13 denotes a latch, which is approximately L-shaped in cross section and whose one end is rotatably supported on a stationary part of the device.
This rotation allows the free end to engage and disengage from the tip of the bar 14 of the entrance/exit door 5. The latch 13 is rotated by the opening of the entrance/exit door 5 since its free end engages with the tip of the bolt 14, but at this time the lever lock member 6 and the lever 12 are not engaged with each other. If the latch 13 is not in the released state, the latch 13 cannot be rotated, and therefore the entrance/exit door 5 cannot be opened. In the figure, reference numeral 15 denotes a micro switch that is opened and closed by the rotation of the latch 13, and the tip of its terminal 16 is brought into contact with the side surface of the latch 13. is pushed in so that the micro switch 15 is closed. The solenoid 8 is configured to stop operating when the micro switch 15 is closed. When the latch 13 and the bolt 14 are disengaged during the opening operation of the entrance/exit door, a well-known coiled spring (not shown) is attached to the rotation axis of the latch 13 so that the latch 13 returns to its original position, that is, the locked position.
The spring elastic force is given by . In this embodiment, the terminal 16 of the micro switch 15
Since the latch 13 is brought into contact with the tip of the terminal 16, the latch 13 is pushed back so that the terminal 16 pushes the latch 13 back.
Together with the return action of the coiled spring wound around the shaft, the return action to the original position is performed. The spring elastic force may be only a coiled spring wound around the shaft of the latch 13, or may be only the elastic force of a spring applied to the terminal 16. By returning the latch 13 to its original position, that is, by pushing back the latch 13 of the terminal 16, the micro switch 15 is opened.

Further, in this embodiment, the lever 12 and the latch 13 are
A pin 17 protruding from the upper end surface of the latch 13 is connected to the latch 13.
is going through. That is, when the latch 13 rotates due to the opening of the entrance/exit door 5, the pin 17 rotates while contacting the side surface of the lever 12, that is, while rotating the lever 12. Conversely, when the latch 13 is pushed back by the terminal 16 of the micro switch 15 and rotates, the pin 17 contacts the side surface of the lever 12 and rotates, so the lever 12 also rotates together with the latch 13. Of course, the connection between the latch 13 and the lever 12 is not limited to this, and the latch 13 and the lever 12 may be formed integrally.

In the figure, reference numeral 21 denotes a starting arm, which is rotatably supported by a shaft 22 on a stationary part of the device. This rotation of the starting arm 21 is carried out by contacting the side end surface of the inserted card 1, and for this purpose, a portion is bent and formed so that the side end surface of the card 1 comes into contact with this bent portion.
The compression coil spring 23 keeps the card 1
A restoring force is provided so that the starting arm 21 rotates in the direction in which it comes into contact with the starting arm 21. Therefore, when the card 1 is inserted, the starting arm 21 rotates clockwise against the restoring force of the compression coil spring 23 to the position shown by the dashed line in FIG. If you pull it out, it will rotate counterclockwise to the position shown by the solid line.

Reference numeral 24 in the figure is a locking plate, one end of which can be engaged with and detached from the starting arm 21 by positioning and retracting the rotation range of the starting arm 21, and the other end is a replacement plate described later. They are pivotally supported 25 so as to be rotatable with respect to each other. That is, the engaging and disengaging operation with the starting arm 21 is performed by rotation around the shaft 25.
Further, the locking plate 24 has one end connected to the starting arm 2.
1, the starting arm 21 can be rotated to be slidable. In this example,
A rotary solenoid 28 having a long hole 26 formed in the locking plate 24 and a pin 27 loosely inserted into the long hole 26.
and the shaft 25, and the elongated hole 2
6 so that the pin 27 can move within the locking plate 2
4 sliding movements are possible. Further, the rotary solenoid 28 disengages the locking plate 24 from the starting arm 21 by rotating clockwise in FIG. When it moves, it can engage with the starting arm 21, that is, it returns to its original position. And the locking plate 24
There is a notch 29 that can be engaged with and disengaged from the locking plate locking member 30.
has been formed.

The locking plate locking member 30 is a plate material having a substantially U-shape, and has a protrusion 31 that projects downwardly at the upper end of the U-shape. The side end faces are U-shaped outwardly inclined slopes 32. Then, the protrusion 31 occupies the insertion movement area of the card 1 to be inserted, and the U-shaped lower end engages with the notch 29 of the locking plate 24 so that it is always positioned by its own weight. When the card 1 is inserted, the leading edge of the card 1 comes into contact with the inclined surface 32 of the protrusion 31, and by further inserting the card 1, the U-shaped inside of the locking plate locking member 30 is inserted. The locking plate locking member 3 is configured to receive the card 1 at the
0 is rotatably supported by a shaft 33 on the stationary part of the device.
Moreover, the locking plate locking member 30 due to this rotational movement
and the notch 29 of the locking plate 24 are disengaged from each other. In other words, the above-described sliding movement of the locking plate 24 accompanying the rotation of the starting arm 21 is prevented when the locking plate locking member 30 and the notch 29 of the locking plate 24 are engaged. Therefore, when the engagement is released, the sliding movement is allowed.

Even when the starting arm 21 and the locking plate 24 are in an engaged state, that is, even when the locking plate 24 is in a state where it can slide as the starting arm 21 rotates, the locking plate locks. Since this sliding movement is prevented by the engagement of the member 30 with the locking plate 24, in order to allow this sliding movement, the locking plate lock must be closed before the side end surface of the card 1 comes into contact with the starting arm 21. The engagement of the member 30 with the locking plate 24 must be released. Therefore, the side edge of the card 1 on the side that comes into contact with the starting arm 21 is cut out to an appropriate length from the tip of the card 1 to form a notch 34. This notch 34
When inserting card 1, first check the length of card 1.
After the distal end edge of the locking plate 30 engages with the protrusion 31 of the locking plate locking member 30 and releasing the engagement of the locking plate locking member 30 with the locking plate 24, that is, the sliding movement of the locking plate 24 is allowed. The length may be such that the side edge of the portion of the card 1 other than the notch 34 comes into contact with the starting arm 21. Furthermore, if the end of the locking plate locking member 30 provided with the protrusion 31 is sufficiently extended toward the insertion slot 2, the leading edge of the card 1 will push up the protrusion 31 and prevent the locking plate 24 from sliding. After allowing
It is also possible to start the contact between the side end surface of the card 1 and the starting arm 21 from the leading edge of the card 1, and in this case, of course, it is not necessary to form the notch 34.

In the figure, reference numeral 35 denotes an exchange plate which is rotatably supported 25 relative to the locking plate 24, and whose substantially central portion is rotatably supported 36 to a stationary part of the device. and pivot support 2
A flexible member 37 is provided protruding from the end opposite to the fifth end, and the lever lock member 6 is attached to the flexible member 37.
is placed thereon, and the lever lock member 6 is connected to rotate as the flexible member 37 rotates in the counterclockwise direction in FIG. 1 along with the exchange plate 35. The connection between the flexible member 37 and the lever lock member 6 is as follows:
As shown in this embodiment, it is preferable to provide an engaging pin 38 projecting from the lever lock member 6 and to place the engaging pin 38 on the flexible member 37 for connection. This exchange plate 35 has its shaft 3
6 is wound with a spring 39, and the lever lock member 6 engages with the lever 12 to lock the lever 12.
In other words, the lever lock member 6
A forced rotational force is applied in a direction that allows rotation in the direction to the original position. In this embodiment, piano wire is used as the flexible member 37.

The operation plate 41 is formed into a substantially L-shape, and has at least one stepped portion 42 at one end on which the tip of the engagement pin 38 of the lever lock member 6 is placed.
The other end is rotatably supported 44 with the connecting member described later.
The substantially central portion is rotatably supported by a shaft 45 on a stationary portion of the device. The stepped portion 42 is designed to prevent the lever lock member 6 from engaging the lever 12 when the engagement pin 38 of the lever lock member 6 is placed thereon, that is, to allow the lever 12 to rotate. A spring 46 is wound around the shaft 45 of the operation plate 41 to apply a forced rotational force so that the stepped portion 42 is located at a position where the engagement pin 38 of the lever lock member 6 can be placed. Furthermore, when the lever lock member 6 is in its original position, its engagement pin 3
The side end surface of the operation plate 41 comes into contact with 8, and the rotation of the operation plate 41 due to the above-mentioned forced rotation force is prevented. Further, the operating plate 41 is provided with an engaging arm 43, and when the lever 12 is rotated when the entrance/exit door 5 is opened, the engaging arm 43 is pushed and the operating plate 41 is moved by a force applied to the operating plate 41. The lever 12 and the engaging arm 43 are arranged to engage with each other so that the lever 12 can be rotated against rotational force.

In the figure, 47 is a connecting member, one end of which is connected to the operation plate 41.
The other end is connected to a pin 27 of the rotary solenoid 28, and the locking plate 24 and the operation plate 41 are connected via the pin 27. . When the locking plate 24 rotates around the shaft 25 due to the operation of the rotary solenoid 28, the connecting member 47 transfers the rotation to the operating plate 4.
I will tell 1. That is, when the locking plate 24 rotates, the operating plate 41 resists the forced rotational force applied to the operating plate 41 by the spring 46 and rotates against the shaft 4.
It will rotate around 5.

7 and 8 show the case where the rotation of the operation plate 41 is caused by the operation of the rotary solenoid 50 through a pin connection 54, in which 51 is the operation plate, 52 is a stepped portion, Reference numeral 53 indicates an engaging arm, which is rotatably supported by a shaft 55 on a stationary part of the device.
A spring 56 is wound around the shaft 55 to provide forced rotational force. And rotary solenoid 5
0 is responsible for the rotation of the operation plate 51, there is no need to provide the connecting member 47.

In the figure, reference numeral 57 indicates a grip portion of the entrance/exit door 5, and when the user grips the grip portion 57 and pulls it toward the user, the entrance/exit door 5 opens. The entrance/exit door 5 is a night latch type door so that it can be opened freely from the inside of the room in which the automatic teller machine or the like is installed, even after the latch 13 has returned to its original position. The bolt 14 is an automatic lock that can be locked automatically.

Since the structure of the locking device of the present invention has been clarified as described above, the details of the operation will be explained below.

At a predetermined time, the main switch of the device is turned on to energize the device, which causes the rotary solenoid 28 to rotate clockwise in the figure and prevent the locking plate 24 from engaging with the starting arm 21. I'll figure it out. That is, in FIG. 3, it rotates about the shaft 25 from the position shown by the solid line to the position shown by the broken line. Due to this rotation, the engagement between the locking plate 24 and the starting arm 21 is released, and at the same time, the engagement between the locking plate 24 and the locking plate locking member 30 is released, and further rotation of the locking plate 24 is released. Connecting member 4
7 to the operating plate 41, the operating plate 41 also rotates about the shaft 45 from the position shown by the solid line in FIG. 4 to the position shown by the dashed line.

When the card 1 is inserted from the insertion slot 2 in this state, if the card 1 has a regular notch 3, the leading edge of the card 1 will not hit the card stopper 4 and will be inserted all the way to the innermost part. Ru. If the code entered by the user by pressing the button matches the code stored in the card 1 in advance, the card reading device 9 is activated and the solenoid 8 is activated.
is activated. As a result of this operation of the solenoid 8, the lever lock member 6 is attracted to the solenoid 8, rotates around the shaft 7 from the position shown by the solid line in FIG. This allows the lever 12 to rotate. Allowing the lever 12 to rotate means allowing the latch 13 to rotate, so that the entrance/exit door 5 can be opened. When the user grasps the grip part 57 and pulls it toward him, the latch 13 rotates due to the door opening operation, and the engagement between the latch 13 and the tip of the bolt 14 is released, thereby opening the entrance/exit door 5. be able to. During this door opening operation, the terminal 16 of the micro switch 15 whose tip is in contact with the side surface of the latch 13 is pushed in by the rotation of the latch 13, and the micro switch 15 is closed. As a result, the solenoid 8 stops its operation and releases the restraint of the lever lock member 6, so that the lever lock member 6 is rotated back to its original position by the restoring force of the spring 10. However, since the lever 12 is in the middle of its rotational movement and is located below the lever locking member 6, the lever locking member 6 rotates back until it comes into contact with the lever 12. When the entrance/exit door 5 is opened and the latch 13 and the bolt 14 are disengaged, the spring elastic force applied to the terminal 16 of the micro switch 15 acts to return the latch 13 to its original position. As the latch 13 returns to its original position, the lever 12 also rotates back to the position where it engages with the lever lock member 6. The user pulls out the card 1 from the insertion slot 2, enters the room where the automatic deposit machine, etc. is installed, and closes the entrance/exit door 5, which is automatically locked and does not perform the above-mentioned normal operations from outside. Otherwise, the entrance/exit door 5 cannot be opened, and automatic teller machines and the like can be operated safely. Further, it is preferable that the automatic teller machine etc. not operate unless the user securely closes the entrance/exit door 5; It is better for safety if the door cannot be opened even if the normal door opening operation is performed.

When leaving the room, the lock on the entrance door 5 is of the night latch type, so the door can be opened from the inside.

The above operation is performed when the device is energized, and the activation of the rotary solenoid 28 causes the starting arm 21, locking plate 24, locking plate locking member 30, replacement plate 35, etc. to prevent the entrance/exit door 5 from opening. It will never be. Further, the operation plate 41 also rotates in conjunction with the rotation of the locking plate 24, and does not engage with the engagement pin 38 of the lever lock member 6. This locking plate 24
It is the connecting member 47 that functions to transmit the rotation to the operation plate 41, and FIGS. 7 and 8 show a case where the need for providing the connecting member 47 is eliminated. That is, by operating the main switch at the predetermined time mentioned above, the rotary solenoid 50 is also activated at the same time as the rotary solenoid 28 is activated, and the operation plate 51 is rotated so that the engagement pin 38 is not restrained in any way. It is something.

Now, the operation of the locking device of the present invention when the power supply to the device is cut off for some reason, that is, during a power outage will be explained. During a power outage, the rotary solenoid 28 does not operate, so when the card 1 is not inserted, each component is in the positional relationship shown by solid lines in each figure.

Then, the inserted card 1 is inserted into the regular notch 34.
If the card 1 is inserted, the leading edge of the card 1 first comes into contact with the protrusion 31 of the lock plate 30 as it is inserted. Further, the insertion of the card 1 proceeds along the slope 32 of the protrusion 31, and the lower end surface of the protrusion 31 is finally placed on the upper surface of the card 1. That is, as the card 1 advances, the protrusion 31 is lifted upward and rotated about the shaft 33 to the position shown by the dashed line in FIG. By this rotation of the locking plate locking member 30, its lower end surface is also lifted upward, thereby disengaging the locking plate 24 from the locking plate 24, and the locking plate 24 becomes slidable. Until the locking plate 24 is disengaged, the card 1 is inserted only by a distance corresponding to the length of the notch 34, and the side end surface of the card 1 is still in contact with the starting arm 21. Not in contact.

As described above, the locking plate 2 of the locking plate locking member 30
When the card 1 is inserted after the engagement with the card 4 is released, the portion of the side end surface of the card 1 that is not the notch 34 starts to come into contact with the starting arm 21, and the card 1 is inserted further. Finally, the starting arm 21
It rotates around the shaft 22 to the position shown by the dashed line in the figure.

In order to properly insert the card 1 that rotates the starting arm 21, the position and length of the notch 3 formed in the card 1 must be compatible with the card stopper 4 fixed to the device. However, in order for the starting arm 21 to rotate properly, the length of the notch 34 of the card 1 must be appropriate. That is, if the notch 3 is not compatible with the card stopper 4, the insertion of the card 1 will no longer be possible when the leading edge of the card 1 comes into contact with the card stopper 4. If the length of the notch 34 is short, the uncut side end surface of the card 1 will come into contact with the starting arm 21 before the locking plate locking member 30 is disengaged from the locking plate 24, so that the card 1 The insertion will stop there. Further, if the length of the notch 34 is long, the starting arm 21 cannot be rotated, or it is not possible to give the starting arm 21 enough rotation to perform the operations of each component as described below. Therefore, depending on the shape of the notch 3 and the notch 34 of the card 1, the card 1
can be a cipher.

When the starting arm 21 rotates properly due to the insertion of the card 1, one end of the locking plate 24 is connected to the starting arm 2.
1, and the locking plate locking member 30 is in a position that allows the locking plate 24 to slide, so as the starting arm 21 rotates, the locking plate 24 will be moved to the position shown by the dashed line in FIG. Furthermore, this locking plate 24
The movement involves rotating the exchange plate 35 around the shaft 36 to the position shown by the dashed line in FIG.
The rotation of the exchange plate 35 causes the lever lock member 6 connected thereto to rotate about the shaft 7 from the position shown by the solid line in FIG. 3 to the position shown by the dashed line. The exchange plate 35 and the lever lock member 6 are connected by placing an engaging pin 38 provided on the lever lock member 6 on a flexible member 37 protruding from the exchange plate, so that when assembling the device, Even if some assembly errors occur, there is no problem in operation.

Before the card 1 is inserted, the operation plate 41 is in the position shown by the solid line in FIG.
The side end surface of the operating plate 41 comes into contact with the engagement pin 38 provided on the lever lock member 6, and further rotation is prevented. When the card 1 is inserted and the lever lock member 6 rotates as described above, the engagement pin 38 is positioned at the position indicated by the dashed line in FIG. 4, and the movement of the engagement pin 38 causes the operation plate 41 to Due to the forced rotation force given to it,
Rotate to the position shown by the two-dot chain line in Figure 4. That is, the stepped portion 42 formed on the operation plate 41 secures the engagement pin 38 and prevents the lever lock member 6 from rotating back to its original position. When the card 1 is pulled out from the insertion slot 2 with the engagement pin 38 secured by the stepped portion 42 of the operation plate 41, the exchange plate 35 is locked by the forced rotation force by the spring 39 applied to the exchange plate 35. The plate 24, the starting arm 21, and the locking plate locking member 30 move to the position shown by the solid line.
The lever lock member 6 is still located at the position indicated by the dotted line in FIG. In order to notify the user that the card 1 can be removed, the operation panel 41 is rotated from the solid line position in FIG. It is also possible to make the card 1 slightly protrude from the insertion slot 2.

When the lever lock member 6 is in the above position, it is in a position where it is disengaged from the lever 12, so that the entrance/exit door 5 can be opened.

When the user opens the entrance/exit door 5, the lever 12 rotates due to the opening operation. This rotation of the lever 12 pushes the engagement arm 43 provided on the operation plate 41 that engages with the lever 12, and the operation plate 41 is rotated to release the engagement pin 38, and the operation plate 41 is released. It will be located at the position shown by the solid line in FIG. When the user finishes his errands and closes the entrance/exit door 5, the locking device will be on standby for the next operation.

Even when the rotary solenoid 50 is responsible for the rotation of the operating plate, the rotary solenoid 50 will not operate during a power outage, and in this case as well, the operating plate 51 will be operated by the engaging pin as in the above-mentioned operating plate 41. 3
8 is secured by the stepped portion 52, and when the lever 12 rotates, the engaging arm 53 is pushed by the lever 12 to release the secured state of the engaging pin 38.

As mentioned above, the locking device of the present invention allows the opening of the entrance/exit door to be performed by the operation of the card reading device, which operates when the card has a regular shape and the code code on the card is correct. It can be used to unlock and unlock the entrance/exit door. In addition, when used as an unlocking device for the entrance/exit door of a room where an automatic cash deposit machine, automatic cash withdrawal machine is installed, or the slot room of a night safe, the card used in the automatic deposit machine, etc. and the entrance/exit door It can also be used in combination with a card used for unlocking the lock, making it an advantageous entrance/exit door unlocking device. In addition, by providing a starter arm, a locking plate, a locking plate locking member, and a replacement plate, even in the event of a power outage, it is possible to unlock the card as long as it has a regular shape, making it extremely practical. It has a high effect.
