Next, the operation of the accommodating device 100 according to the present embodiment will be described below. The accommodating device 100 can carry out each step of the initial step, the sterilization step, and the final step. When using the accommodating device 100, the operator first turns on the power. When the accommodating device 100 is operated by a dry battery, the operator installs the dry battery in advance in a dry battery mounting portion (not shown) of the accommodating device 100. When the accommodating device 100 operates on AC power, the operator keeps the accommodating device 100 connected to the source of AC power. After turning on the power, the operator operates the operation unit 62 to start the operation of the accommodating device 100. After turning on the power, the control device 90 first carries out an initial process.

The initial step is a step for satisfying the required amount of bactericidal component in the accommodating portion 2. In the initial step, the control device 90 operates the sterilizer 3. At this time, the control device 90 operates the sterilizing component supply mechanism 41 to operate both the sterilizing component generator 42 and the first blower 43. By the operation of the bactericidal component generator 42, the bactericidal component is generated in the first chamber 37. Further, the operation of the first blower 43 causes an air flow in the housing 31. That is, by the operation of the first blower 43, the air outside the accommodating device 100 flows from the suction unit 45 into the housing 31, passes through the sterilizing component generator 42 and the first blower 43, and is accommodated from the supply unit 19. It flows into 2.

When the air flowing in from the suction unit 45 passes through the sterilizing component generator 42, the sterilizing component generated by the sterilizing component generator 42 is added. Then, the air containing this bactericidal component is supplied from the supply unit 19 to the storage unit 2.

In the initial step, the control device 90 continues the operation of the sterilizing component supply mechanism 41 for a predetermined time, so that the air containing the bactericidal component is continuously supplied into the accommodating portion 2 for a predetermined time. For example, the control device 90 generates a sterilizing component having a predetermined initial concentration for a predetermined time such as 20 minutes from the start of operation in the initial process, and operates the first blower 43 with a predetermined initial blowing amount.

The concentration of the bactericidal component in the accommodating portion 2 increases with the passage of time in the initial process. The air that existed in the accommodating portion 2 before the operation of the bactericidal component supply mechanism 41 was introduced into the insertion portion 11, the gap between the accommodating main body 25 and the lid 24, and the side plates 26-29 of the accommodating portion 2. , The side plate 26-29, the bottom plate 30, etc. gradually leak to the outside. Then, the concentration of the sterilizing component in the accommodating portion 2 gradually increases to reach a predetermined concentration at which the sheet can be sterilized in a predetermined time.

After a predetermined time has elapsed from the start of the initial process, the control device 90 shifts to the sterilization process. In the sterilization step, the control device 90 switches the amount of the sterilizing component generated by the sterilizing component generator 42 to a predetermined constant concentration lower than the initial concentration. Further, the air volume of the first blower 43 is switched to a predetermined steady air volume smaller than the initial air volume. Alternatively, both the bactericidal component generator 42 and the first blower 43 may be temporarily stopped for a predetermined time.

When the sheet is inserted from the insertion unit 11, the bactericidal component filled in the storage unit 2 sterilizes pollutants and harmful substances such as dust, viruses, bacteria, and mold adhering to the sheet. The sheet is exposed to, contacted with, and sterilized by many bactericidal components while falling from the insertion section 11 to the lower part of the housing section 2.

Since the supply mechanism 41 is installed in the upper part of the accommodating portion 2, immediately after the sheet is inserted from the insertion portion 11 provided on the upper surface of the accommodating portion 2 than when it is installed in the lower part, and during its fall. More bactericidal components can be brought into contact with the sheet.

Even after the sheet has landed on the lower part or the bottom of the accommodating portion 2, the sterilizing component of the accommodating portion 2 can continue to sterilize the sheet. In particular, when the sterilizing component is a substance heavier than air such as ozone, it tends to accumulate in the lower part of the accommodating portion 2, so that the sheet can be efficiently sterilized while the sheet is accommodating in the lower part of the accommodating portion 2. can.

In the sterilization step, the control device 90 maintains the concentration of the sterilizing component in the accommodating portion 2 so as not to fall below a predetermined sterilizing concentration, and controls the sheet inserted from the inserting portion 11 to continue in a sterilizable state. As described above, by shifting from the initial step to the sterilization step, the control device 90 can fill the accommodating portion 2 with a sufficient amount of sterilizing component in a short time in the initial step. In addition, the supply amount of the sterilizing component in the sterilizing step can be suppressed.

Then, it is possible to prevent the bactericidal component from being excessively generated and leaking to the installation location of the accommodating device 100. It is possible to prevent the bactericidal component generator 42 from generating a bactericidal component in excess of the required amount, and to prevent the concentration of the bactericidal component from increasing around the installation location of the accommodating device 100 and adversely affecting the human body of the operator. In addition, when a bactericidal component such as ozone or chlorine has an odor, it is possible to prevent the worker from being offended or feeling ill.

Further, by controlling the presence of a bactericidal component that sterilizes the sheet in the accommodating portion before inserting the sheet into the accommodating portion 2, the sheet can be appropriately inserted even when the first sheet is inserted. Can be sterilized. The transition timing from the initial step to the sterilization step may be earlier or later than the timing at which the first sheet is inserted into the accommodating portion 2.

The concentration of the bactericidal component is measured by the detection unit 15 and transmitted to the control device 90. The control device 90 feeds back the measured value of the obtained bactericidal component, and adjusts the amount of the bactericidal component generated by the bactericidal component generator 42 based on the feedback. That is, the detection unit 15 measures the concentration of the bactericidal component every unit time. The control device 90 compares the set value with the measured value sent from the detection unit 15, and controls the operation of the sterilizing component generator 42 and the first blower 43 based on these. In the control device 90, the sheets are appropriately sterilized in the accommodating unit 2 according to the additional pace of the sheets sequentially inserted from the insertion unit 11, the amount of the sheets already accommodated in the accommodating unit 2, the surrounding environment, and the like. Concentration of bactericidal component required for sterilization, amount and time of generation in sterilization component generator 42, amount of supply to storage unit 2, exposure time in storage unit 2, timing of transition from initial process to sterilization process, etc. The values obtained from the experimental results etc. are set.

The time required for the sheet to be sterilized with the bactericidal component may be short if the concentration of the bactericidal component is high, and long if the concentration of the bactericidal component is low. The time required for sterilization can be, for example, 20 seconds to 60 minutes, preferably 30 seconds to 30 minutes, and more preferably 1 minute to 20 minutes. The CT value, which is the product of the concentration (mass ppm) of the bactericidal component in the accommodating portion 2 and the treatment time (minutes), is preferably 100 to 6000 ppm · min, more preferably 200 to 4000 ppm · min, and even more preferably. Is 300 to 2000 ppm / min. When the CT value is within an appropriate range, viruses, fungi, molds and the like can be properly killed, and the residual amount of contaminants and harmful substances on the sheet after treatment can be reduced.

Instead of adjusting the concentration of the bactericidal component using the measured value of the measuring unit 15, the operation of the bactericidal component generator 42 is started and stopped at a predetermined timing using the internal clock, and the accommodating unit 2 is adjusted to the expected concentration of the bactericidal component. It may be controlled so as to. In this case, it is not necessary to install an expensive bactericidal component measuring device, so that the cost can be reduced.

When the sterilization of the sheet is finished, the control device 90 shifts to the finishing step. In the end step, the control device 90 prepares to end the sterilization process of the sheet accommodated in the accommodating unit 2. The end step is carried out when the stop unit 66 is operated by the operator. Further, the control device 90 can also carry out the termination process when a safety sensor (not shown) installed at any place detects a danger in operation.

In the final step, the bactericidal component supplied to the storage unit 2 and staying in the storage unit 2 is reduced, removed, detoxified, and detoxified. The sterilizing component used for sterilization in the storage unit 2 is taken out from the extraction unit 20, the concentration is reduced by the removal unit 52, and the sterilizing component is removed and then discharged to the outside. In the final step, the control device 90 stops the sterilizing component generator 42 and operates the second blower 53. At this time, the first blower 43 continues to operate.

By stopping the bactericidal component generator 42, the air supplied to the accommodating portion 2 does not contain the bactericidal component. Further, by the operation of the second blower 53, the air in the accommodating section 2 is taken out from the taking-out section 20, flows into the second chamber 38, reaches the removing section 52, passes through the second blower 53, and is sent from the discharging section 55. It is discharged to the outside. The removing unit 52 removes the bactericidal component contained in the air taken out from the accommodating unit 2.

Since the removal mechanism 51 is installed in the lower part of the accommodating portion 2, when the bactericidal component is a substance heavier than air, the bactericidal component can be efficiently recovered.

After starting the end step, when a predetermined time required for the sterilizing component contained in the air contained in the accommodating unit 2 to be removed by the removing unit 52 elapses, the control device 90 sets the first blower 43 and the second. Both blowers 53 are stopped.

As described above, in the final step, the air in the accommodating portion 2 is sequentially replaced with the external air containing almost no bactericidal component from the state containing the bactericidal component having a predetermined concentration. In the state where the sheet is sterilized in the sterilization step, the air in the accommodating portion 2 contains a predetermined amount of the sterilizing component, and the concentration of the sterilizing component is higher than that of the outside air.

If the lid 24 is opened for the purpose of taking out the sheet while the bactericidal component concentration is high, the operator may inhale the bactericidal component having a predetermined concentration into the body through the nose or mouth. Therefore, the operator opens the lid 24 and replaces it with the air outside the apparatus main body 1 before the operator touches the air inside the accommodating portion 2. As a result, even if the lid 24 is opened, the operator can avoid the danger of coming into contact with air having a high concentration of bactericidal components or inhaling into the body.

From the above, the accommodating device 100 according to the present embodiment sterilizes the accommodating portion 2 accommodating the sheet, the inserting portion 11 for inserting the sheet into the accommodating portion 2, and the sheet accommodated in the accommodating portion 2. Since the sheet is provided with the part 4, when the sheet is accommodated, even if a virus, fungus, mold, pollen, etc. are attached to the sheet, there is a risk that a worker who touches the contained sheet will be infected. It can be reduced.

Further, since the sterilizing unit 4 includes a supply unit 19 for supplying the sterilizing component for sterilizing the sheet to the accommodating unit 2, the sterilizing component generated outside the accommodating unit 2 can be easily stored. 2 can be supplied, and the sheet can be easily sterilized by the sterilizing component.

Since the supply unit 19 is composed of an opening provided in the side plate 26 of the storage unit 2, the bactericidal component can be easily supplied to the storage unit 2.

Further, since the sterilizing unit 4 is provided with a sterilizing component generator 42 for generating a sterilizing component for sterilizing the sheet, the sterilizing component generator 42 can easily generate the sterilizing component.

Further, since the sterilizing component generator 42 is detachably installed on the accommodating portion 2, the sterilizing component generator 42 can be attached to the accommodating portion 2 only when the sheet needs to be sterilized.

Further, it is provided with an extraction unit 20 for taking out the air contained in the accommodation unit 2 to the outside of the accommodation unit 2, and a removal unit 52 for removing at least a part of the bactericidal component remaining in the air taken out by the extraction unit 20. Therefore, the air in the accommodating unit 2 can be easily taken out by using the taking-out unit 20, and by removing the bactericidal component by the removing unit 52, it is possible to suppress the discharge of air containing a large amount of bactericidal component to the outside. ..

Further, if the sheet is at least one of the ballots, postcards or envelopes used during the election, these ballots, postcards or envelopes can be efficiently sterilized.

Further, since the sterilizer 4 can be operated by both an AC power source and a dry battery, it is more convenient than a case where only an AC power source or a dry cell can be used.

Further, when the containment device 100 is used as an election ballot box, the inserted ballot can be sterilized. Therefore, the ballot can be sterilized and safe before performing the manual confusion work on the opening table. Even if there is an infected person such as a virus among the people who voted, the pollutants adhering to the ballot can be sterilized and the spread of the pollutants can be avoided.

It is possible to prevent the air discharged from the unit 55 from directly hitting the operator.

(Fifth Embodiment)
The accommodating device 100d according to the fifth embodiment of the present invention will be described below. FIG. 13 is a partially enlarged cross-sectional view of the accommodating device 100d according to the fifth embodiment. In the first to fourth embodiments, the bactericidal component generated by the bactericidal component generator 42-42c is supplied from the supply unit 19-19c to the storage unit 2-2c, but in the fifth embodiment, this is used. Instead, the sheet is sterilized by the sterilizing unit 4d provided in the accommodating unit 2d. The sterilizing unit 4d includes an ultraviolet generator 47 that generates ultraviolet rays.

The ultraviolet generator 47 is installed in the vicinity of the insertion portion 11d. Two insertion openings 12d are provided on the top plate 23d of the accommodating portion 2d.

Further, a control device 90d is vertically installed on the lower surface of the top plate 23d between the two insertion openings 12d. The ultraviolet generator 47 is installed outside the guide 13 installed with the insertion port 12d interposed therebetween.

By installing the guide 13 between the passage path of the sheet and the ultraviolet generator 47, it is possible to prevent the sheet inserted from the insertion port 12d from coming into contact with the ultraviolet generator 47. Therefore, when the ultraviolet generator 47 generates heat, it is possible to avoid adversely affecting the sheet. That is, for example, when the sheet is surface-treated with a resin or the like, the guide 13 is used to insulate the ultraviolet generator 47 from being damaged, so that the sheet can be prevented from being damaged. Further, it is possible to eliminate the risk that the sheet comes into contact with the generated ultraviolet generator 47, adheres to it, cannot fall, stays on the upper part of the accommodating portion 2d, and clogs the insertion portion 11d.

The guide 13 is preferably made of a material having a high ultraviolet transmittance. Specifically, as the guide 13, quartz glass, crystal or the like can be used. Since the guide 13 is made of a material having a high ultraviolet transmittance, the ultraviolet rays transmitted through the guide 13 can easily reach the sheet. When the UV transmittance of the guide 13 is not high, the sheet can be irradiated with ultraviolet rays by providing openings, slits, holes and the like for irradiating the sheet with ultraviolet rays.

Since the sterilizing unit is provided with an ultraviolet generator that generates ultraviolet rays, the sheet can be effectively sterilized using ultraviolet rays.

It can be installed on at least one of the upper part, the upper part, the lower part, the bottom part, and the left and right side surfaces of the accommodating part. Further, the sterilizing component generator may not be removable and may be configured so that it cannot be removed while being fixed to the accommodating portion.

Further, the bactericidal component supply mechanism 41 may be installed inside the accommodating portion. When the supply mechanism of the bactericidal component is installed inside the accommodating portion, it is not necessary to provide the supply unit in the accommodating portion. It also eliminates the need for the first blower. The suction part is also unnecessary. The bactericidal component generator can be installed on the bottom plate inside the housing. Further, the bactericidal component generator can be attached to at least one of the inner surface of the side plate of the accommodating portion and the lower surface of the top plate. By attaching the bactericidal component generator to the side plate of the accommodating portion or hanging it on the lower surface of the top plate, the bactericidal component generated from the bactericidal component generator can be easily filled in the accommodating portion. In this case, it is possible to prevent the diffusion of the bactericidal component from being hindered by the sheets stacked and stored in the lower part of the storage portion. When the supply mechanism is installed inside the accommodating portion, the removal mechanism may be provided outside the accommodating portion or inside the accommodating portion. Further, only the removing portion may be installed inside the accommodating portion, and the second blower may be installed outside the accommodating portion at a position where the air that has passed through the removing portion can pass. Furthermore, it is possible to configure the structure without installing a removal mechanism.

Further, when the accommodating portion 2b was attached to the receiving portion 82, the accommodating portion 2b was formed to be higher than the four side walls 76-79 of the receptor 81 by a predetermined amount so that the upper portion of the accommodating portion 2b protruded from the upper surface of the receptor 81. However, the height may be the same, and the side wall may be formed so as to be higher than the upper surface of the accommodating portion by a predetermined amount. Further, the accommodating portion may be configured to be completely covered with the receiving portion. The upper surface of the side wall may be set higher than the accommodating portion, and a lid may be provided on the receiving portion so that the entire accommodating portion can be accommodated in the accommodating portion. In this case, it is necessary to form the sheet insertion portion by aligning it with the insertion portion of the accommodation portion at least on either the lid or the side wall of the receptor. As a result, not only the sheet accommodated in the accommodating portion but also the entire accommodating portion can be sterilized.

Further, although the ultraviolet generator 47 is attached to the lower surface of the top plate, it may be another inner wall surface of the accommodating portion. Further, although the accommodating device 100 is provided with the removing portion 52, the accommodating device 100 may not be provided with the removing portion, and the air in the accommodating portion may be discharged to the outside of the accommodating device and diffused without being collected.
