【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a lock mechanism of this embodiment, FIG. 2 is an enlarged view of a main part of FIG. 1, and FIG. 3 is a perspective view showing a state in which the lock mechanism is viewed from the inside of a denomination cassette. 1 to 3, reference numeral 25 is a denomination-type cassette as a storage unit, and 26 is a main body of the denomination-type cassette 25, which is a box type for storing bills and the like and has an opening surface on one side, A door 27 for opening and closing this opening surface is attached.

The door 27 is attached to one side of the main body 26 so that it can be opened and closed via a hinge 28, and a key to be described later is inserted on the free end side opposite to the hinge 28. It has an insertion hole 29 for removing. Numeral 30 is a key for inserting and unlocking the main body 26 and the door 27 from the insertion hole 29 into the lock 31 provided on the main body 26 side, and as shown in FIG. It is composed of an insertion portion 30a and a knob portion 30b for supporting the insertion portion 30a and allowing the user to pinch and operate the insertion portion 30a. The knob portion 30b has a diameter larger than that of the insertion hole 29 provided in the door 27. The knob portion 30b is formed in a wide size so that it cannot penetrate the insertion hole 29.

The inner surface side of the above-mentioned outer surface side structure has a structure as shown in FIG. Reference numeral 31 denotes a lock that locks and unlocks the lock by inserting the key 30 and rotating it. The lock 31 overlaps with the position of the insertion hole 29 formed in the main body 26 when the door 27 is closed, and has a corresponding arrangement. , Attached to the body 26. Reference numeral 32 denotes a key lever provided at the rear end (the front side in FIG. 3) of the lock 31, which projects radially from the peripheral surface of the lock 31 and rotates integrally with the lock 31.

Reference numeral 33 is a latch bracket arranged so that the tip and the lower end of the key lever 32 are engaged with each other. The latch bracket 33 is rotatably attached to the back side of the main body 26 with the stud 34 as a fulcrum, and will be described later. An engagement protrusion 33a for engaging with the lock plate is formed so as to protrude in the rotation direction of the latch bracket 33. Reference numeral 35 denotes a stopper fixed to the inner surface of the main body 26 by welding or the like so as to be interposed between the latch bracket 33 and the main body 26, and restricts the turning operation of the latch bracket 33 at a predetermined angle.

Reference numeral 36 denotes a lock plate, one side of which is L-shaped and is fixedly arranged at a predetermined position inside the door 27 by welding or the like, and is projected so as to stand inside the door 27. The other side has an engagement hole 36a that engages with the engagement protrusion 33a of the latch bracket 33. Numeral 37 is a torsion spring, one end of which is attached to the stopper 35 and the other end of which is attached to the latch bracket 33 via the stud 34. The torsion spring 37 urges the latch bracket 33 so as to always rotate toward the lock plate 36. There is.

Next, the operation of this embodiment having the above-mentioned configuration will be described. When the door 27 of the denomination cassette 25 is to be opened, the key 30 is inserted into the insertion hole 29 provided in the door 27 as shown in FIG. Since the insertion hole 29 is a mere through hole that penetrates the door 27, the insertion portion 30 a of the key 30 penetrates the insertion hole 29 and is inserted into the lock 31 provided in the main body 26.

Since the key 30 is thus inserted into the lock 31, when the key 30 is rotated in a predetermined direction to unlock the lock, here, the key lever 32 shown in FIG. 3 rotates together with the lock 31. , Abuts against the lower end of the latch bracket 33 and presses it. The pressing force of the key lever 32 causes the latch bracket 33 to rotate in the direction of the arrow in the figure against the biasing force of the torsion spring 36. By this rotation, the engaging protrusion 33a of the latch bracket 33 comes out of the engaging hole 36a of the lock plate 36, the engagement is released, the lock between the door 27 and the main body 26 is released, and the door 27 can be opened. It becomes a state.

Therefore, the operator holds the handle 27 (not shown) while pulling the door 27 while turning the key 30 and pulls the door 27 toward the front side to slightly rotate the door 27. At this time, the key 30 is still in the insertion hole 29 and the lock 31. In other words, if the key 30 is pulled out from the lock 31 before the door 27 is rotated, the lock structure described above is an auto-lock mechanism when it is closed, so that the latch bracket 33 is locked by the biasing force of the torsion spring 36. This is because the door 27 is locked by turning in the direction of returning to the original position, the engaging projection 33a again entering into the engaging hole 36a of the lock plate 36 and engaging with it.

Therefore, the key 30 is pulled rightward, that is, the state where the engagement between the latch bracket 33 and the lock plate 36 is released is held, and the door 27 is pulled toward the front side. When the door 27 is opened, the key 30 is still inserted in the lock 31, and the knob portion 30b of the key 30 is larger than the insertion hole 29 of the door 27. The periphery of the insertion hole 29 collides with the portion 30b and the opening is blocked. That is, the door 27 cannot be opened with the key 30 still inserted.

Therefore, the operator pulls out the key 30 from the lock 31 and the insertion hole 29 while holding the door 27 at a position where it is slightly rotated. As a result, since the knob portion 30b that obstructs the opening of the door 27 is eliminated, the door 27 is completely opened. After opening the door 27 in this manner, a predetermined work, for example, bill loading, filling or collecting work is performed, and when the work is completed, the door 27 is closed and locked. Incidentally, the locking operation of the lock of the door 27 may be performed only by closing the door 27 to the main body 26. That is, as described above, the latch bracket 33 is constantly urged by the torsion spring 36 in the direction in which it engages with the lock plate 36. Therefore, when the key 30 is pulled out from the lock 31, it engages with the lock plate 36. When it returns to the engaged position and receives a pressing force in the direction against the torsion spring 36, it retracts from the engaged position.

Therefore, when the door 27 is closed, the lock plate 36 provided inside the door 27 comes into contact with the tapered surface of the engaging projection 33a and is further pressed, so that the latch bracket is inserted through this tapered surface. 33 is pressed and rotated. In this way, when the tip of the lock plate 36 passes through the engaging projection 33a and reaches the engaging hole 36a, the engaging projection 33a enters the engaging hole 36a and the door 27 The body 26 is locked.

Further, when the key 30 is inserted into the lock 31 during the closing operation of the door 27, the knob portion 30b of the key 30 causes the door 27 to collide with the rear end of the knob portion 30b and cannot be closed. .. In the above-described embodiment, the device provided with this lock mechanism is a denomination cassette for storing bills included in the automatic teller machine, but the present invention is not limited to this, and a lock and a key are provided. It goes without saying that it can also be applied to other devices that are installed.
