In the embodiment, the stamping device 2 which is an accessory device fixed to the door 12 fixes the stamping device 2 by an operation of fixing a plurality of locking devices to the door 12 without welding. Specifically, the stamping device 2 is sandwiched so as to be tightened by the fixing members 16 of the plurality of locking devices. More specifically, the fixing member 16 is screwed into the locking device so that a part of the locking device located on the surface side of the door 12 and the fixing member 16 are brought close to each other and the door 12 is interposed between them. The stamping device 2 is tightened so as to be fixed to the door. Further, the marking device 2 of the embodiment includes a penetrating portion 84 into which the handle portion 13 can be inserted and a penetrating portion 85 into which the unlocking portion 14 can be inserted.

As described above, the locking device operated from the front surface side of the door 12 is the delivery box 1 tightened and fixed by using the fixing member 16 located on the back surface of the door 12, and the stamping device 2 is the fixing member 16. If the door 12 is tightened and fixed at a plurality of places using the above, the welding step can be omitted, and since no welding mark or the like remains on the surface side of the door 12, the design can be improved. ..

Further, if the locking devices are arranged side by side in the vertical direction, positioning at the time of mounting the marking device 2 becomes easy. Further, if one of the locking devices is a handle portion 13 for opening / closing operation and one of the other locking devices is an unlocking portion 14 used for unlocking the door 12. It can be composed of only necessary parts.

Further, the door 12 is provided with a display unit 15 used for visually recognizing that the door is locked. The back surface of the door 12 is provided with a stamping device 2 used for stamping the receipt.

The stamping device 2 includes a main body portion 21 having a pressing portion 31 used for stamping the stamp 91. A pressing portion 31 is attached to the main body portion 21 so as to be slidable. Further, the main body portion 21 is covered with the cover portion 24, and the seal 91 is protected from rainwater or the like in a state where the door 12 is open. The cover portion 24 is detachably fixed by being screwed to the main body portion 21.

The stamping device 2 provided in the delivery box 1 of the embodiment has an introduction port 23 through which the receipt is inserted when the receipt is moved toward the receipt placement unit 22 on which the receipt is placed at the time of stamping, on the back surface of the door 12. Preparing for. That is, since the introduction port 23 is not provided on the surface side of the door 12, it is possible to provide the delivery box 1 in which water does not enter from the surface of the door 12. Therefore, if the door 12 is closed, the waterproofness of the delivery box 1 can be ensured.

In the embodiment, the main body 21 of the stamping device 2 includes a stamping mechanism 39 and a receipt arranging section 22 that move during the stamping operation. It also includes a stamping mechanism 39 and a cover portion 24 that covers the receipt arranging portion 22. Further, an introduction port 23 is provided between the receipt arrangement unit 22 and the cover unit 24. By making the cover portion 24 cover the stamping mechanism 39 and the receipt arranging portion 22, even if the door 12 is opened, water does not easily enter the portion where the stamping work is performed. Although the introduction port 23 of the embodiment has a slit shape into which the receipt can be inserted, it may be configured in an opening shape into which the receipt can be introduced.

The stamping device 2 of the embodiment includes a pressing portion 31 that is operated at the time of stamping. The pressing portion 31 that is pressed at the time of stamping is provided on the back surface side of the door 12. Therefore, both the work of inserting the receipt into the introduction port 23 and the work of pressing the pressing portion 31 for stamping can be performed on the back surface side of the door 12, and the workability is improved.

The pressing portion 31 of the embodiment has a structure as shown in FIG. As can be understood from FIGS. 9 to 12, when the pressing portion 31 is in the initial position where it is not pressed, the clasp 41 can be freely moved within a range of approximately 90 degrees by moving the handle portion 13. It can be rotated. Therefore, if the handle portion 13 is moved to the closed position with the door 12 closed with respect to the box main body 11 and the clasp 41 is caught with respect to the box main body 11, the door 12 is maintained in the closed state. be able to. Further, the door 12 can be opened by moving the handle portion 13 to the open position to release the state in which the clasp 41 is caught on the box body 11.

On the other hand, as can be understood from FIGS. 13 to 16, when the pressing portion 31 is pressed and the regulating portion 42 moves to the regulated position, the moving range of the stopper 41 is suppressed. Specifically, since the movement range of the stopper 41 is suppressed, the movement range of the handle portion 13 is suppressed, so that the handle portion 13 cannot be moved from the closed position to the open position. Explaining with reference to the figure, the receipt is inserted with the door 12 open, and the pressing portion 31 is pressed as shown in FIG. Then, after closing the door 12, the handle portion 13 is operated to change from the state shown in FIG. 13 to the state shown in FIG. In the state shown in FIG. 14, even if the handle portion 13 is operated to be returned to its original position, the restricting unit 42 makes it impossible to return to the state shown in FIG.

In this way, the lock structure is provided with a clasp 41 that is rotated by the operation of the handle portion 13 and a pressing portion 31 that is used to move the position of the regulating portion 42. If the restricting portion 42 is in a state of restricting the rotation of the clasp 41 by operating 13, the regulating portion 42 regulates the rotation of the clasp 41 until the pressing portion 31 is pressed. Since there is no such thing, it is possible to avoid a state in which the handle portion 13 is unintentionally locked while being operated. In addition, a person who does not have the key can perform the locking operation.

By arranging the pressing portion 31 operated at the time of stamping in a biased manner toward the plurality of locking devices, the mechanism can be miniaturized, so that the left-right balance of the pressing portion 31 can be prevented from being lost. , Can be moved up and down stably.

As shown in FIGS. 8 and 11, the pressing portion 31 of the embodiment includes a stamp 91, a regulating member 43, and a holding metal fitting 45. Therefore, when the pressing portion 31 is moved, the stamp 91, the regulating member 43, and the holding metal fitting 45 are interlocked with each other. The regulating member 43 provided with the regulating portion 42 is rotatably attached to the pressing portion 31, but one end of the regulating member 43 urged by the spring portion 92 is separated from the main body portion 21. When it is moved in this way, when the force becomes smaller than the urging force, it moves to return to the original position side.

As shown in FIGS. 11, 12, 15, and 16, the holding metal fitting 45 is provided in the pressing portion 31 so as to be able to be locked to the holding portion 44 provided in the main body portion 21. When the holding metal fitting 45 moved by moving the pressing portion 31 moves to a predetermined position, the holding portion 44 engages the holding metal fitting 45 so that the pressing portion 31 returns to the initial position by the tension spring 95 described later. Suppress doing.

The holding metal fitting 45 is rotatably attached to the pressing portion 31, but the holding metal fitting 45 urged by the spring portion 93 is moved so that one end thereof is separated from the main body portion 21. , When the force becomes smaller than the urging force, it moves to return to the original position side.

As in the embodiment, if the configuration includes a holding metal fitting 45 that interlocks with the pressing portion 31, and a holding portion 44 that locks the holding metal fitting 45 and holds the pressing portion 31 in a pressed state, the marking is provided. By the operation, the movement of the handle portion 13 can be regulated.

Further, the holding metal fitting 45 is pivotally supported by the pressing portion 31, and a holding piece 46 locked to the holding portion 44 is provided on one end side of the shaft portion 48 that pivotally supports the holding metal fitting 45, and the holding metal fitting 45 is provided. A release piece 47 serving as a release portion is provided on the other end side of the shaft portion 48 that supports the shaft. As shown in FIG. 25, the release piece 47 is exposed from the cover portion 24 after the operation of the pressing portion 31.

Further, when the locking of the holding metal fitting 45 and the holding portion 44 is released by operating the release piece 47, the pressing portion 31 is moved by the urging force, and the regulating portion 42 rotates the clasp 41. If the configuration is provided with a tension spring 95 for releasing from the restricted state, the spring is held in a spring-urged state after stamping, and the rotation of the stopper 41 is restricted by the operation of the release piece 47. It can be released. Even if the pressing portion 31 is pressed by an erroneous operation in the open state of the door 12 after the pressing portion 31 is pressed and the rotation of the stopper 41 is restricted, the release piece 47 can be removed from the back surface of the door 12. This state can be canceled by operation.

Since the regulating member 43 is similarly pivotally supported by the pressing portion 31, if the side opposite to the regulating portion 42 can be pressed, the regulating portion 42 can press the stopper 41 by pressing the portion. It is also possible to lift the state of restricting movement. That is, the portion of the regulating member 43 opposite to the regulating portion 42 can be used as the releasing portion. In this case, if the handle portion 13 is operated while pushing the release portion provided on the regulating member 43, the handle portion 13 can be freely rotated.

Further, one of the release portions is a locking device that is operated from the surface side of the door 12 to rotate the holding portion 44, so that if a resident or the like operates from the outside of the door 12, the clasp 41 can be used. The state in which rotation is restricted can be released.

Here, an example of how to use the delivery box 1 will be described. In the delivery box 1 of the embodiment, the clasp 41 can be rotated by rotating the handle portion 13 provided on the surface side of the door 12. When the clasp 41 is caught on the box body 11, the opening of the door 12 is suppressed, but when the handle portion 13 is rotated to release the state in which the clasp 41 is caught on the box body 11, the door 12 is opened. be able to. As a result, the delivery person can put the package in the delivery box 1.

After opening the door 12, the delivery person moves the receipt toward the receipt arrangement unit 22 through the introduction port 23, and arranges a part of the receipt so as to face the receipt arrangement unit 22. After that, the delivery person presses the pressing portion 31 inside the delivery box 1 downward to stamp the receipt. Since a part of the receipt is supported by the receipt arrangement unit 22, it can be appropriately stamped.

Further, as can be understood from FIGS. 15 and 16, when the pressing portion 31 is pressed, the holding metal fitting 45 attached to the pressing portion 31 moves so as to get over the holding portion 44. At this time, the holding metal fitting 45 receives a force from the holding portion 44 and is displaced, but the holding metal fitting 45 that has passed over the holding portion 44 is released from the state of receiving such a force from the holding portion 44. On the other hand, the force from the spring portion 93 tries to return to the original state. Therefore, the holding metal fitting 45 is in a state where the moving range is restricted by the holding portion 44. In addition, the moving range of the pressing portion 31 is restricted. The regulating unit 42 also moves by pressing the pressing unit 31, but when the movement range of the pressing unit 31 is restricted, the restricting unit 42 is arranged at a position where the movement of the clasp 41 can be restricted. Will be done.

By the way, in order to make the pressing portion 31 slidable with respect to the main body portion 21, the main body portion 21 is provided with a slide groove 32. Further, the pressing portion 31 is provided with a guide pin 33. As can be understood from FIGS. 16 and 17, the slide groove 32 is formed so that the holding portion 44 can further slide from the state where the holding metal fitting 45 is held, and the marking fails. Also, the stamping work can be done again.

When the door 12 is closed and the handle portion 13 is rotated in the state shown in FIG. 16, the clasp 41 moves so as to push away the restricting portion 42 as shown in FIG. When the clasp 41 rotates beyond a predetermined position, the state in which the clasp 41 and the regulating portion 42 are in contact with each other is released. Since the regulating portion 42 does not receive the force from the clasp 41, it tries to return to the original state by the force from the spring portion 92. As a result, the regulating unit 42 is arranged at a position as shown in FIG. 19, and the movement of the stop 41 is set at a regulateable position. Therefore, the movement range of the handle portion 13 is restricted, and the door 12 can be maintained in a state in which it cannot be opened.

On the other hand, a person on the manager side of the delivery box 1, such as a landlord or an installer, releases the state in which the movement of the holding metal fitting 45 is restricted by the holding portion 44 by operating the unlocking portion 14 from the surface of the door 12. be able to. More specifically, as shown in FIG. 20, by turning the key inserted in the unlocking portion 14 to rotate the holding portion 44, the state in which the movement of the holding metal fitting 45 is restricted can be released. .. Then, the pressing portion 31 urged by the tension spring 95 returns to the position shown in FIG. 11, so that the handle portion 13 can move normally and the door 12 can be opened.

By the way, the delivery box 1 of the embodiment is provided with a display unit 15 so that it can be seen that the door 12 is in a locked state. In the embodiment, the door 12 is provided with a hole 94 in order to form the display portion 15.

In the embodiment, a part of the display member 51 attached to the inside of the delivery box 1 is colored so as to be different from the other parts, and is it in a locked state due to the difference in color seen through the hole 94? It can be determined whether or not.

Since the display member 51 is attached to the pressing portion 31, it moves in conjunction with the pressing portion 31. In the state before the pressing portion 31 is pressed, the lower portion of the display member 51 is visible through the hole portion 94, but by pressing the pressing portion 31, a portion colored in red provided above the portion is formed. Will be located so as to face the hole 94.

As can be understood from FIG. 21, in the embodiment, the hole portion 94 is not always visible from the outside, and when the handle portion 13 is in a predetermined state, the hole portion 94 is configured so as not to be visible. Has been done. More specifically, as shown in FIGS. 21 (b) and 21 (c), when the handle portion 13 is in the open position, the handle portion 13 is positioned so as to cover the hole portion 94, and FIGS. 21 (a) and 21 (a). As shown in d), when the handle portion 13 is in the closed position, the handle portion 13 is configured to be positioned so as not to cover the hole portion 94. In addition, in FIG. 21, FIG. 21A shows a state in which the stopper 41 is in the closed position and the pressing portion 31 is not pressed, and FIG. 21B shows the state in which the stopper 41 is in the open position. 21 (c) shows a state in which the pressing portion 31 is not pressed, FIG. 21 (c) shows a state in which the clasp 41 is in the open position and the pressing portion 31 is pressed, and FIG. 21 (d) shows a state in which the clasp 41 is pressed. Is in the closed position and represents a state in which the pressing member 31 is pressed. That is, in the state of FIG. 21C, the display member 51 visible from the hole portion 94 is already in a state of indicating the closed position, but the display portion cannot be visually recognized because the structure is covered by the handle portion 13. The structure is such that the display member 51 is exposed by rotating the handle portion 13 as shown in FIG. 21 (d).

In order to have such a configuration, the handle portion 13 having a substantially circular shape in a side view is configured to include a notch portion 18 as if a part thereof is notched. When the handle portion 13 is formed in a crescent shape in this way, the orientation of the handle portion 13 becomes easy to see. In addition, a notch may be provided inside the circular handle portion 13 in a circular shape in a side view so that the hole 94 can be visually recognized through the notch.
