As a result, the communication unit 33 receives the signal transmitted from the mobile terminal 70 by operating the mobile terminal 70, and outputs the received signal to the control device 43. As will be described later, when the lock portion 35 is locked in the second locked state by pressing the delivery button 39 described later in the closed state of the door 16, the unlock code is input to the unlock code input unit 31. As a result, the lock portion 35 is unlocked.

The power supply unit 34 includes a battery and supplies electric power to the motor 37a (FIG. 4) constituting the control device 43 and the bolt drive unit 37 described later.

FIG. 4 is a schematic view showing the latch bolt 36 and the bolt drive portion 37 of the electronic lock 20 and the latch receiving portion 13a provided on the box body 13 in a locked state of the door 16. The lock portion 35 of the electronic lock 20 has a latch bolt 36 and a bolt drive portion 37, and has a function of keeping the door 16 in a closed state. The latch bolt 36 is urged by the spring 35a in a direction protruding outward from the side wall portion of the left side L of the case 21 (FIG. 2). The bolt drive unit 37 has a motor 37a, a first gear 37b fixed to the motor shaft of the motor 37a, a second gear 37c that meshes with the first gear 37b, and a lever 37d fixed to the second gear 37c.

A lever 37d engages with the inner end of the latch bolt 36. The power of the motor 37a is transmitted to the lever 37d via the first gear 37b and the second gear 37c, and the latch bolt 36 can be moved in the protruding direction or the retracting direction. The motor 37a is controlled by the control device 43. When the motor 37a is driven in the positive direction (arrow A direction in FIG. 4) by supplying power to the motor 37a, the second gear 37c rotates in one direction (arrow B direction in FIG. 4) to cause the lever 37d. The engaged latch bolt 36 retracts to the inside of the case 21 (FIG. 2) against the urging force of the spring 35a. At this time, even when the lock portion 35 is unlocked and the door 16 is closed, the latch bolt 36 retracts from the latch receiving portion 13a provided at the portion facing the left L end of the door 16 of the box body 13. Therefore, the door 16 can be opened and closed.

On the other hand, when the motor 37a is driven in the opposite direction by the power supply to the motor 37a and then the drive of the motor 37a is stopped by the stop of the power supply, the latch bolt 36 is subjected to the urging force of the spring 35a in the case 21 (FIG. It protrudes to the outside of 2). When the door 16 is closed in this state, the latch bolt 36 enters the latch receiving portion 13a and the state is maintained, so that the lock portion 35 is locked and the door 16 cannot be opened. The configuration of the lock portion 35 is not limited to the configuration shown in FIG. 4, and various configurations can be adopted.

For example, the character "open" is displayed on the open button 38. After the lock unit 35 was unlocked by inputting the unlock code to the unlock code input unit 31, that is, after the door 16 was opened and closed, that is, the door 16 was opened, and then the door 16 was closed.

In the "second locked state", the control device 43 unlocks the lock unit 35 only when the unlock code is input to the unlock code input unit 31. Thereby, the unlocking of the lock portion 35 can be limited to a specific user who can input the unlocking code.

The first lighting unit 40 and the second lighting unit 41 are configured to include a light source such as a light emitting diode (LED). The first lighting unit 40 can change the color at the time of lighting. For example, each first lighting unit 40 can be lit in either green or red. The lighting state of each of the lighting units 40 and 41 is controlled by the control device 43. Further, although not shown, an audio output unit is arranged in the case 21, and the operation of the audio output unit is controlled by the control device 43.

The door sensor 42 has, for example, a pressing portion 42a (FIG. 2) that is urged to project outward from the case 21 by a spring, and the pressing portion 42a is fixed to the box body 13 in the closed state of the door 16. However, the contact is closed and turned on by being pushed so that the amount of protrusion is small. On the other hand, in the door sensor 42, the pressing portion 42a is not pushed when the door 16 is open, and the contact is opened and turned off by increasing the amount of protrusion thereof. As a result, the door sensor 42 detects the open / closed state of the door 16 depending on the on / off state. The detection signal of the door sensor 42 is output to the control device 43.

The control device 43 includes, for example, an arithmetic processing unit composed of an MCU (Micro Controller Unit) and a storage unit. The storage unit may be a RAM, a ROM, or the like. The arithmetic processing unit has a function of reading and executing a program or the like stored in advance in the storage unit. The storage unit has a function of temporarily storing the read program and processing data, and a function of storing a control program, a predetermined threshold value, and the like in advance.

By executing the program by the control device 43, the main function of the device, system, or method in the present disclosure is realized. The arithmetic processing unit may be of any type as long as the function can be realized by executing the program. For example, the arithmetic processing unit may be a CPU. The arithmetic processing unit may be composed of one or a plurality of electronic circuits including a semiconductor integrated circuit (IC) or an LSI (large scale integration). A plurality of electronic circuits may be integrated on one chip or may be provided on a plurality of chips. A plurality of chips may be integrated into one device, or may be provided in a plurality of devices. A non-temporary recording medium such as an optical disk or a hard disk drive may be used as the storage unit. An external storage device may be connected to the control device 43 as a storage unit. The program may be stored in a recording medium in advance, or may be supplied to the recording medium via a wide area communication network including the Internet or the like.

The control device 43 controls so that the door 16 can be opened and closed when the lock unit 35 is unlocked by inputting the unlock code to the unlock code input unit 31. The unlocking code input may be performed using the mobile terminal 70 or may be performed using the numeric keypad operation unit 32. Further, the control device 43 unlocks the lock portion 35 after unlocking the lock portion 35 by inputting the unlock code, after the door 16 is opened and closed, that is, after the door 16 is opened and then the door 16 is closed. It is controlled to be locked in the first locked state. At this time, the control device 43 determines the open state of the door 16 by using the detection signal of the door sensor 42.

Further, the control device 43 controls the lock portion 35 to be locked in the second locked state when the delivery button 39 is pressed while the door 16 is closed.
