The right gear 42 is moved to the left to move deeper into the guide groove 46. Therefore, it returns to an initial state (lock state).

In this process, the linear motion of the front and rear rack gears 32 is maintained linearly by the electronic opening and closing storage box 11 which slides in the main body 11a, and the linear motion of the left and right rack gears 42 is It is held linearly by the guide walls 48.

By the above configuration, the electronic open / close storage box 11 is opened and closed under the instruction of the controller 16 in the locked state.

Hereinafter, a fingerprint recognition key storage procedure performed by the controller 16 will be described with reference to the flowchart of FIG. 3.

When the operation of the fingerprint recognition type key storage device is started, the control unit 16 is in a waiting state waiting for an instruction of a command or a button selection, and is activated by selecting a storage button or a find button to execute a storage mode or a search mode. (S300).

To this end, the controller 16 checks the button selection of the input unit 13 in the standby state. At this time, the electronic opening and closing storage box 11 is a locked state in which the guide protrusion 44 is located inside the guide groove 46, and is in a state that cannot be opened from the outside.

In the above state, when the storage button of the input unit 13 is selected by the user (S301), the controller 16 finds an empty box among the plurality of electronic open / close boxes 11 and displays it on the display unit 14 (S302). ). Here, the check of the empty storage box may be determined by using the weight detection sensor 52 provided in the electronic open / close storage box 11 to determine that the electronic open / close storage box having a weight less than or equal to the standard value is an empty storage box. The control unit 14 includes a table for managing whether the storage box 11 is used or not, and displays the busy opening / closing box 11 in which the user selects and registers the fingerprint. In this case, it is possible to confirm the empty electronic opening and closing library by only inspecting the set table.

As such, when the empty storage box 11 is displayed on the display unit 14, the user may select one of the displayed storage boxes.

The control unit 16 displays the empty storage box, and then inspects the input unit 13 to check whether one of the displayed empty storage boxes is selected (S303). At this time, if a predetermined time is set and the storage box is not selected within the set time, the process returns to the standby state (S300).

When the predetermined storage box 11 is selected as a result of the check, the controller 16 outputs a message for requesting a fingerprint input to the user through the display unit 14 or the speaker unit 15 (S304).

In addition, it is checked whether a fingerprint is input through the fingerprint recognition unit 12 (S305). At this time, if the fingerprint is not input within a predetermined time, it returns to the standby state (S300).

As a result of the check (S305), if the fingerprint is input, it is determined whether the input fingerprint is a new fingerprint or already registered fingerprint (S306). This is to prevent the same fingerprint from being registered twice and malfunctioning, which is possible by comparing the characteristics of the fingerprint registered with the previously registered fingerprint.

If the fingerprint inputted above is not a new fingerprint, an error message, for example, a registered fingerprint, is output through the display unit 14 or the speaker unit 15 so as to guide the user to select a find button. After returning to the standby state (S300) (S307).

On the contrary, when the input fingerprint is a new fingerprint, the input fingerprint is registered as an authentication means of the selected storage box (S308).

Then, the selected electronic lock box 11 is opened (S309). That is, the control unit 16 applies a predetermined electric drive signal to the motor 34 so that the electronic open / close storage box 11 moves forward.

By the control signal of the controller 16 as described above, the motor 34 of the electronic open / close box 11 rotates to release the locked state, and the selected electronic open / close box 11 is advanced by a predetermined distance. Accordingly, a predetermined storage space provided in the electronic open / close storage box 11 is exposed to the user, and the user may insert an article such as a key into the exposed storage space.

As such, in order to confirm whether the key is stored, the controller 16 opens the selected electronic open / close box 11 and then outputs an output signal of the weight detection sensor 52 provided in the automatic open / close box 11. Through the inspection of the weight change of the electronic open and close storage box (11). In addition, the elapsed time after the electronic open and close storage box 11 is opened (S310).

As a result of the check, when the weight of the automatic open / close box 11 is increased (S311), it is determined that the user has inserted a key, and outputs a close signal to the automatic open / close box 11 (S314). The close signal becomes a reverse rotation instruction signal of the motor 34.

In addition, if the weight of the automatic open / close storage box 11 does not increase, when a predetermined time or more passes, it is determined as an abnormal state and outputs an error message through the display unit 14 or the speaker unit 15, and the registered fingerprint. Cancel (S313). Subsequently, a close signal is output to the electronic open / close box 11 (S314).

Next, when the user selects the find button in the input unit 13 (S315), the control unit 16 outputs a fingerprint input request message through the display unit 14 or the speaker unit 15 (S316). In step S317, the fingerprint is checked through the fingerprint recognition unit 12. In addition, the elapse of time after outputting the fingerprint input request message is checked (S318).

As a result of the check, if the fingerprint is not input within the set time, the process returns to the standby state S300 and waits for a retry.

On the contrary, if the fingerprint is input through the fingerprint recognition unit 12 within the set time, it is determined whether there is a matching fingerprint by comparing the input fingerprint with the previously registered fingerprint (S319). If it is determined that the fingerprint is not registered, the display unit 14 or the speaker unit 15 notifies the registered fingerprint and outputs a message to select a storage button (S320).

When the input fingerprint is a registered fingerprint, an operation signal is applied to the motor 34 of the electronic open / close storage box 11 to open the electronic open / close storage box 11 (S321). The opening operation of the electronic opening and closing storage box 11 is made as shown in FIG.

In addition, in order to determine whether the user has taken the key stored in the electronic open / close box 11, the weight detection sensor 52 provided in the electronic open / close box 11 is input to change the weight of the electronic open / close box 11. Inspect (S322).

As a result of the check, when the weight of the electronic open / close box 11 decreases, it is determined that the user has taken the key, the registered fingerprint is deleted (S324), and the electronic open / close box 11 is closed (S325). Closing operation of the electronic open and close storage box 11 is made as shown in FIG.

As described above, the fingerprint recognition key storage device according to the present invention is used together with the existing key-type storage box by opening and closing the storage box by distinguishing the user by using the fingerprint, the key of the storage box It can be stored simply and securely, and as a result, while eliminating the inconvenience of storing the key when using the existing item storage box, there is an excellent effect of reducing unnecessary resource waste by using the existing key-type item storage box.
