The partition plate 15 and the shutter cover 16 have coin storage ports 15a and 16a (15a is not shown) corresponding to the storage port 3b, and the partition plate 15 has a bow-shaped groove 15b. A rectangular groove 16b and a rectangular cutout window 16c are provided in each.

A shutter plate 20 is disposed in a gap between the partition plate 15 and the shutter cover 16, and the shutter plate 20 is swingably supported by a pin 21 planted in the partition plate 15. By the spring 23 hung between the cut-and-raised part 20a and the pin 22 planted on the partition plate 15, the coin storage port 16a is closed, and a turning habit is imparted in the counterclockwise direction in FIG. The rotation is restricted by the stopper pin 24 that is planted in the partition plate 15.

A bow-shaped pressing portion 20b is formed on one edge of the shutter plate 20, and two engaging projections 20c and 20d are formed on the upper end of the pressing portion 20b so as to project. A shutter pin 20e fitted in the groove 15b is planted on the upper surface of the portion. As shown in detail in FIG. 4, a shielding portion 25, which is thinner than the shutter plate 20 having an arcuate groove 25a, is provided outside the pressing portion 20b so as to face the cutout window 16c of the shutter cover 16. The plate 20 is formed so as to integrally project in a stepwise manner.

Below the cutout window 16c of the shutter cover 16, a box-shaped shutter lock cover 27 having a window 27a is attached. A lock lever 30, a lock cam 40, and a bracket 45, which are shown in detail in FIG. 6, are arranged in the shutter lock cover 16. The lock lever 30 has a claw portion 30a at one end, a pressed portion 30b at the other end, a projection 30c on the lower surface between the pressed portion 30b and the center, and a cylindrical portion 31 formed on the lower surface of the center. The preset lever portion 32 is integrally formed on the lower end surface of the tubular portion 31.

The lock lever 30 is rotatably supported by the shaft portion 33 fitted in the partition plate 15 and inserted in the groove 25 a so that the cylindrical portion 31 is fitted therein and is rotatably supported. It is elastically held by a coil spring 35 that is stretched over the protrusion 30c. The pin 34 serves as a fixed fulcrum of the spring 35, and the projection 30c serves as a dynamic fulcrum. With the line K connecting the pin 34 and the shaft 33 as a boundary line, the projection 30c, which is the dynamic fulcrum, moves clockwise and counterclockwise. It constitutes a tumbler mechanism that reverses.

The lock cam 40 is provided with a pair of upper and lower restricting surfaces 41a and 41b on the peripheral surface of which a notch is formed by notching at a predetermined angle, and has a ridge line shape along which the preset lever portion 32 abuts along the tip direction. A pair of upper and lower cam surfaces 42a and 42b are provided and are swingably supported by a bracket 45, which will be described later, around the pin 44. The bracket 45 is fixed to the inner surface of the main body 2 and has a cut-and-raised portion 45a as a stopper portion with which the cam surfaces 42a and 42b are engaged. The lock cam 40 has a cut-and-raised portion on the cam surfaces 42a and 42b. It has a play and is swingable in a range where it engages with 45a.

The present invention is configured as described above, and the operation will be described below. When the charge box 1 is taken out from the safe 10 to collect the charge, the shutter plate 20 is rotated counterclockwise by the urging force of the spring 23 and hits the stopper pin 24 as shown in FIG. In this state, the coin storage port 16a is closed by the shutter plate 20, and the claw portion 30a of the lock lever 30 is engaged with the engaging protrusion 20c of the shutter plate 16, so that the shutter plate 20 is in this state. It is possible to prevent illegal removal of coins from the coin storage opening 16a of the charge box 1 which is held in the safe box 10.

At this time, since the engagement portion between the claw portion 30a and the engagement protrusion 20c is covered by the shielding portion 25 of the shutter plate 20 which faces the cutout window 16c of the shutter cover 16, the coin storage port of the lid 3 is covered. Even if an attempt is made to disengage the engaging portion between the claw portion 30a and the engaging protrusion 20c with a thin member such as wire from the gap between the shutter plate 20 and the shutter plate 20, it is blocked by the shielding portion 25. Unauthorized removal of coins is prevented. In this embodiment, the engagement portion between the claw portion 30a and the engagement protrusion 20c is mainly covered, but the cutout window 16c is entirely covered in order to prevent fraud more completely. Is also possible.

Next, the operation of presetting the shutter plate 20 will be described. In order to collect the charge, as shown in FIG. 7 (a), the locking sealing device (not shown) is unlocked and removed from the locking hole 6a of the fixed locking piece 6, and the locking metal fitting 7 is gripped with a finger to cover the lid 3. When opened, the lock lever 30 rotatably supported by the shaft 33 planted in the partition plate 15 is also lifted upward together with the lock lever 30. At this time, the lock cam 40 shown in FIG. 5 is rotated clockwise by its own weight so that the lower regulating surface 41a is engaged with the cut-and-raised portion 45a of the bracket 45, as shown in FIG. 7B. The portion 32 abuts the lower engaging surface 42a of the lock cam 40 to rotate the lock cam 40 counterclockwise about the pin 44 by a predetermined angle, and the upper restricting surface 41b engages with the cut-and-raised portion 45a to lock the lock cam 40. The rotation stops.

By providing the lock cam 40 with a play that allows the lock cam 40 to rotate by a predetermined angle, the external force that is suddenly applied to the preset lever 32 when the lid 3 starts to be opened is absorbed by the preset lever 32. It is possible to prevent the lock cam 40 from being damaged. Subsequently, when the lid 3 is opened, the lock cam 40 stops rotating, so that the preset lever portion 32 whose one side edge 32a contacts the lower engaging surface 42a of the lock cam 40 is in the direction of arrow A in FIG. 7 (b). That is, when it is rotated counterclockwise about the shaft 33, the lock lever 30 also starts to rotate counterclockwise against the coil spring 35.

Further, when the lid 3 is opened and the contact portion 32 a of the preset lever portion 32 is located at the tip end which is a boundary portion between the upper and lower engaging surfaces 42 a and 42 b of the lock cam 40 as shown in FIG. The protrusion 30c, which is the fulcrum of the lever 30, is located on the boundary line K. If the lid 3 is continuously opened from this state, the dynamic fulcrum 30c is reversed from the boundary line K, so that the lock lever 30 is rotated counterclockwise about the shaft 33 to rotate the claw portion 30a as shown in FIG. Is in a so-called preset state in which the engagement with the engagement protrusion 20c is released and the rotation restriction of the shutter plate 20 is released. At the same time, the pressed portion 30b of the lock lever 30 contacts the pressing portion 20b of the shutter plate 20.

When the lid 3 is closed again after the charge is collected, the preset lever portion 32 retains the state shown in FIG. 9, that is, the non-engaged state with the lock cam 40, so the shutter plate 20 also shows in FIG. Holds the preset state of the open state. FIG. 10 shows a special state. For example, in the case where the collector 3 operates the lock lever 30 from the gap such as the shutter lock cover 27 after opening the lid 3 to release the preset state of the shutter plate 20. , Again to explain the preset operation.

That is, at this time, the lock lever 30 is reversed, and the one side edge 32 b of the preset lever portion 32 is in contact with the upper engagement surface 42 b of the lock cam 40. When the lid 3 is closed in this state, the lower engagement surface 41a of the lock cam 40 abuts against the cut-and-raised portion 45a, and the rotation thereof is restricted. Therefore, the preset lever portion 32 rotates in the direction of arrow A to lock the lock lever 30. Also rotates counterclockwise about the shaft 33, and the shutter plate 20 is again in the preset state shown in FIG. When the shutter plate 20 is set to the preset state when the lid 3 is opened and closed, the upper and lower engaging surfaces 41a and 41b of the lock cam 40 with which the one side edges 32a and 32b of the preset lever portion 32 come into contact are formed in ridge lines. The rotation of the lock lever 30 is smoothly performed.

Next, the operation of storing the fee box 1 in the safe 10 will be described. After sealing the locking hole 6a of the fixed locking piece 6 with the locking sealer and storing the money box 1 in the safe room 10 as shown in FIG. 11, the pressing plate 12 of the safe room 10 is pushed from the slit 3c of the lid 3 into the safe room 10. When it enters the lid 3, the pressing groove 12a engages with the shutter pin 20e of the shutter plate 20 to rotate the shutter plate 20 against the spring 23 in the clockwise direction in the figure about the pin 21. Along with this rotation, the pressed portion 30b of the lock lever 30 that is in contact with the pressing portion 20b of the shutter plate 20 is also pressed, and the lock lever 30 is rotated clockwise about the shaft 33 to swing. The fulcrum 30c is located on the boundary line K. At this time, the preset lever portion 32 is positioned diagonally below the lower engagement surface 42a of the lock cam 40 as shown in FIG.

Further, when the charge box 1 is stored in the safe room 10, the lock lever 30 is reversed, the claw portion 30a abuts the pressing portion 20b of the shutter plate 20, and the claw portion 30a engages with the engaging protrusion 20c. To be engageable with. As shown in FIG. 12, when the charge box 1 is completely stored, the coin storage opening 16a is opened from the closed state of the shutter plate 20 so that coins can be stored. At the same time, it is located below the lower engagement surface 42a of the lock cam 40.

Finally, when the charge box 1 is taken out of the safe room 10 to collect the charge, the pressing plate 12 retracts from the lid 3, so that the shutter plate 20 is rotated counterclockwise by the biasing force of the spring 23. The coin storage port 16a is moved to be closed, and the claw portion 30a of the lock lever 30 is engaged with the engagement protrusion 20c, so that the state shown in FIG. 3 is obtained. Here, the engagement protrusion 20d functions as a preliminary engagement protrusion when the claw portion 30a cannot engage with the engagement protrusion 20c, and completely locks the shutter plate 20 of the lock lever 30. Is.

In the present embodiment, the lock cam 40 is provided with a play that is rotatable by a predetermined angle. However, the structure is not limited to this, and the lock cam 40 is provided with an elastic member such as a spring so that the lock cam 40 can be rotated in one direction. By providing the elastic member, the rotation of the lock cam 40 at the time of opening and closing the lid 3 is restricted, so that the same impact absorption effect can be obtained. The same effect can be obtained by attaching a shock absorbing member such as rubber to the periphery of the lock cam 40 and the cut-and-raised portion 45a of the bracket 45.
