Description

Technical Field

[0001] The present invention relates to a sterilizer for smartphones.

Background Art

[0002] The penetration rate of smartphones is increasing, and the usage rate per day is also increasing. Since a smartphone is touched on the screen with a finger or the like during use, fingerprints and the like adhere to the screen and become dirty during use. Therefore, fingerprints and the like are removed by wiping the surface with a cleaning cloth or the like at an appropriate timing.

Summary of the Invention

Problems to be Solved by the Invention

[0003] On the other hand, it has been reported that various bacteria and viruses adhere to the surface of smartphones. In addition, during the COVID-19 pandemic, regular alcohol disinfection and the like have become habitual, and alcohol liquid is sprayed, and alcohol-based wet tissues and the like are used to directly disinfect fingers or wipe the surfaces of daily necessities for sterilization.

[0004] Therefore, it is preferable that the surface of the smartphone can be wiped with, for example, a wet tissue impregnated with alcohol liquid for the purpose of sterilizing the surface of the smartphone following the cleaning of habitual daily necessities, or as a target for sterilizing the surface of the smartphone. However, wiping the monitor screen with alcohol is not preferable because it causes deterioration of the screen coating. In addition, when a liquid crystal protection film or the like is attached to the monitor screen of the smartphone or when it is coated, although deterioration of the liquid crystal screen does not occur even when sterilization is performed using an alcohol liquid, deterioration of the liquid crystal protection film or the coating is caused, and their replacement cycles are shortened. Therefore, there is a demand to sterilize the surface of the smartphone without causing such a situation.

[0005] The above-described problems are described as independent ones, and the present invention does not necessarily have to solve all of the described problems, and it is sufficient if at least one problem can be solved. Also, regarding the configuration for solving this problem, it has the intention of obtaining rights by filing a divisional application or making a correction alone, etc.

Means for Solving the Problem

[0006] In order to solve the above-described problems, the sterilizer for a smartphone according to the present invention includes: (1) a case body with one side open, a drawer part that can be slid and moved relative to the case body and can be stored, and a smartphone stand detachably mounted in the drawer part. A first ultraviolet irradiation unit that emits ultraviolet rays downward and is attached at a predetermined upper position inside the case body, and a second ultraviolet irradiation unit that emits ultraviolet rays upward and is attached to the inner bottom surface side of the case body. The smartphone stand is formed of a material that transmits ultraviolet rays. The smartphone stand has a part on its upper surface that supports the smartphone. When the smartphone stand is set in the drawer part and the drawer part is stored in the case body, the part is separated from the irradiation position of the ultraviolet rays in the second ultraviolet irradiation unit by a predetermined distance, and a predetermined space is secured between the upper surface of the smartphone placed on the smartphone stand and the irradiation position of the ultraviolet rays in the first ultraviolet irradiation unit.

[0007] Place the smartphone on the upper surface of the smartphone stand in any vertical orientation, and in that state, push in the drawer-type drawer part and store it in the case body. Then, the upper surface of the smartphone faces the first ultraviolet irradiation unit. As a result, the ultraviolet rays emitted from the first ultraviolet irradiation unit are irradiated onto the surface on the upper surface side of the smartphone set on the smartphone stand, and sterilization, disinfection, etc. are performed.

[0008] Also, the surface on the lower surface side of the smartphone placed on the smartphone stand faces the smartphone stand, and in a state where the drawer portion is stored in the case body, it faces the second ultraviolet irradiation unit below the smartphone stand. And since the smartphone stand is formed of a member that transmits ultraviolet rays, the ultraviolet rays emitted from the second ultraviolet irradiation unit pass through the smartphone stand and irradiate the surface on the lower surface side of the smartphone, and disinfection and sterilization are performed. In this way, both sides of the smartphone can be disinfected at the same time without using alcohol or the like.

[0009] (2) The smartphone stand may be configured to have a through-hole through which the ultraviolet rays emitted from the second ultraviolet irradiation unit pass. By doing so, a part of the ultraviolet rays emitted from the second ultraviolet irradiation unit passes through the through-hole and is directly irradiated onto the smartphone for disinfection and the like. Furthermore, when there is a through-hole, it gives the user a feeling that ultraviolet rays pass well and gives the user peace of mind.

[0010] (3) The region including the center of the upper surface of the smartphone stand may be provided with a recess that is one step lower than the outer periphery, and the bottom surface of the recess may be the portion for the smartphone with a small size, and the outer periphery may be the portion for the smartphone with a large size. By doing so, a small-sized smartphone can be positioned and disinfected while suppressing lateral displacement as much as possible.

[0011] (4) The height of the smartphone stand may be such that the ultraviolet rays emitted from the first ultraviolet irradiation unit and the ultraviolet rays emitted from the second ultraviolet irradiation unit irradiate a wide range of the upper and lower surfaces of the smartphone placed on the smartphone stand. By doing so, the entire surface of the smartphone can be efficiently disinfected and the like.

[0012] (5) Either one of the first ultraviolet irradiation unit and the second ultraviolet irradiation unit may be provided with a function of generating ozone.

[0013] (6) The first ultraviolet irradiation unit and the second ultraviolet irradiation unit may be configured to emit ultraviolet rays of the same wavelength.

Advantages of the Invention

[0014] According to the present invention, without alcohol disinfection, it is possible to disinfect both the surface having the monitor screen of the smartphone and the surface on the opposite side thereof, such as sterilization.

Modes for Carrying Out the Invention

[0016] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. It should be noted that the present invention is not construed as being limited thereto, and various changes, modifications, and improvements can be made based on the knowledge of those skilled in the art without departing from the scope of the present invention.

[0017] Figures 1 to 6 show a preferred embodiment of a sterilizer for a smartphone according to the present invention. The sterilizer for a smartphone according to this embodiment includes a case body 11 having a substantially rectangular shape with one side open, a drawer part 12 that can be detachably attached to the inside of the case body 11 from the opening 11a of the case body 11, a first ultraviolet irradiation unit 13 and a second ultraviolet irradiation unit 14 attached to a predetermined position on the inner surface of the case body 11, and a smartphone stand 15 or the like that is detachably attached inside the drawer part 12.

[0018] The case body 11 is configured by butting a first case 21 and a second case 22 that are divided into two parts vertically. The first case 21 located on the upper side is composed of a hollow rectangular box shape with an open lower surface and a side surface on one short side. The second case 22 located on the lower side is composed of a hollow rectangular box shape with an open upper surface and a side surface on one short side. Then, the first case 21 and the second case 22 are fixed with screws or the like in a state where the upper and lower open end faces are butted against each other, and a hollow case body 11 having an opening 11a on one short side is formed.

[0019] The drawer part 12 is composed of a substantially rectangular box body in the shape of a tray with an open upper part. Both ends in the longitudinal direction, that is, one surface on the short side, becomes the front surface 12a, and the other surface becomes the back surface 12b. By inserting the back surface 12b of the drawer part 12 into the opening 11a of the case body 11 and pushing it all the way in, the drawer part 12 is housed inside the case body 11. Also, when the drawer part 12 is housed by pushing it in all the way like this, the front surface 12a of the drawer part 12 enters the opening 11a of the case body 11 and closes the opening 11a.

[0020] The first ultraviolet irradiation unit 13 is attached to a predetermined position on the top surface 21a of the inner peripheral surface of the first case 21. The first ultraviolet irradiation unit 13 arranges an operation button 26, a notification LED 27, etc. on one first surface 25a of a flat rectangular substrate 25, arranges a first ultraviolet light emitting part 29 on the opposite second surface 25b, and provides a predetermined circuit such as a control circuit and a power supply circuit for controlling the light emission of the notification LED 27 and the first ultraviolet light emitting part 29 on one or both of the first surface 25a and the second surface 25b.

[0021] The notification LED 27 notifies the operating state etc. of the sterilizer for smartphones by changing the emission color and blinking state. In this embodiment, a plurality (for example, three) are arranged in a straight line at equal pitches. The control of the emission of this notification LED 27 is, for example, to assign one of the three (in this example, the side of the opening 11a) to the LED that notifies the emission state of the first ultraviolet light emitting unit 29, and for example, change the emission color according to the lighting / extinguishing of the first ultraviolet light emitting unit 29, or for example, when the first ultraviolet light emitting unit 29 is lit, the notification LED 27 is also lit, and when the first ultraviolet light emitting unit 29 is extinguished, the notification LED 27 is also extinguished. Also, the remaining two of the three notification LEDs 27 may, for example, indicate the operating status (for example, ON / OFF) of the drying fan 28 described later or the charging state. Also, without being limited to these, it may be used for indicating the operating status etc. of devices and equipment etc. mounted on the sterilizer for smartphones.

[0022] On the other hand, a second ultraviolet irradiation unit 14 is provided on the lower part of the inner peripheral surface of the case body 11, that is, on the inner bottom surface of the second case 22. Similar to the first ultraviolet irradiation unit 13, the second ultraviolet irradiation unit 14 has two second ultraviolet light emitting parts 42 provided at a predetermined distance along the longitudinal direction on one surface of the substrate 41. The installation positions of these two second ultraviolet light emitting parts 42 are set to be positions facing the installation position of the first ultraviolet light emitting part 29. Further, this second ultraviolet light emitting part 42 emits ultraviolet light of a predetermined wavelength, similar to the first ultraviolet light emitting part 29, and it is advisable to use ultraviolet LEDs of the same rating. Thereby, ultraviolet light of the same wavelength is emitted. The power supply voltage for driving this second ultraviolet irradiation unit 14 may be received from the built-in battery, for example, in the same manner as the first ultraviolet irradiation unit 13.

[0023] The operation button 26 is arranged on the extension line of the three notification LEDs 27. The operation button 26 is, for example, a push-type button switch. This operation button 26 functions as, for example, a power switch, and the sterilizer for smartphones starts operating when the power is turned on. For example, the control circuit that controls the lighting of the first ultraviolet light emitting part 29 and the second ultraviolet light emitting part 42 is such that when the operation button 26 is pressed when the first ultraviolet light emitting part 29 and the second ultraviolet light emitting part 42 are turned off, the first ultraviolet light emitting part 29 and the second ultraviolet light emitting part 42 emit light, and when the operation button 26 is pressed when the first ultraviolet light emitting part 29 and the second ultraviolet light emitting part 42 are emitting light, the first ultraviolet light emitting part 29 and the second ultraviolet light emitting part 42 are turned off.

[0024] Also, instead of repeating the lit state and the extinguished state every time the operation button 26 is pressed, for example, when the operation button 26 is briefly pressed, the first ultraviolet light emitting part 29 and the second ultraviolet light emitting part 42 emit light, and when the operation button 26 is long-pressed, the first ultraviolet light emitting part 29 and the second ultraviolet light emitting part 42 are controlled to turn off. In this way, even if the user presses the operation button 26 twice or accidentally presses the operation button 26 during operation, the first ultraviolet light emitting part 29 and the second ultraviolet light emitting part 42 can continue to emit light without turning off. And when the user wants to intentionally turn off the light during the emission of the first ultraviolet light emitting part 29 and the second ultraviolet light emitting part 42, the user can turn it off by consciously long-pressing.

[0025] Also, in this embodiment, the first ultraviolet light emitting part 29 and the second ultraviolet light emitting part 42 are turned on and off integrally based on the operation of the operation button 26, but they may be turned on and off independently and separately. However, if they are configured to be turned on and off integrally as in this embodiment, it is possible to suppress as much as possible the occurrence of a situation where one side is not irradiated due to forgetting to turn on one of the ultraviolet light emitting parts.

[0026] Furthermore, after the first ultraviolet light emitting unit 29 and the second ultraviolet light emitting unit 42 are turned on, it is preferable to have a function of turning off after a predetermined time has elapsed. The predetermined time may be, for example, a time sufficient for sterilizing or disinfecting a smartphone. By doing so, even after the sterilization of the smartphone is completed, continuous lighting can be suppressed, and it is possible to prevent the battery capacity of the built-in battery from being wasted needlessly.

[0027] Furthermore, the control circuit of the notification LED 27 may vary the lighting state of the notification LED 27 according to the remaining battery capacity. For example, the emission color, the presence or absence of blinking, the blinking time, etc. may be changed. When notifying the remaining battery capacity using a plurality of notification LEDs 27, it is preferable to increase or decrease the number of notification LEDs 27 according to the remaining capacity. Also, when charging, it may be lit in an appropriate pattern to indicate that it is charging, and lit so that the current battery capacity can be known.

[0028] As described above, the first ultraviolet irradiation unit 13 is fixed to the top surface 21a of the inner peripheral surface of the first case 21. At this time, the first surface 25a of the substrate 25 of the first ultraviolet irradiation unit 13 is mounted so as to face the top surface 21a, and through holes 21b are provided at the portion of the top surface 21a facing the operation button 26 and the notification LED 27, and the operation button 26 and the notification LED 27 are configured to be exposed to the outside.

[0029] On the other hand, one or a plurality of the first ultraviolet light emitting units 29 are arranged in a predetermined pattern on the second surface 25b of the substrate 25. The first ultraviolet light emitting unit 29 is composed of a lamp, an LED, etc. that emit ultraviolet light capable of sterilizing or disinfecting. For example, it is good to use a phosphor in the wavelength range of UV-C of 100 to 280 nm. In this embodiment, a 260 nm ultraviolet LED is used. The irradiation area of the ultraviolet light emitted from the first ultraviolet light emitting unit 29 may be set in terms of the installation position and arrangement pattern so as to cover almost the entire internal space of the case body 11. In this embodiment, they are arranged at two locations at a predetermined interval along the longitudinal direction. The number of LEDs arranged at one location is arbitrary.

[0030] On one side surface 21c of the long side of the first case 21, a power supply port 30 for charging is provided, and a USB female connector is arranged on the back side of the power supply port 30. And this USB female connector is connected to the built-in battery via a charging circuit. By attaching the male connector of a predetermined charging cable to the USB female connector arranged at the power supply port 30, the battery can be charged.

[0031] Also, a ventilation port 21d is provided on one side surface 21c of the long side of the first case 21, and a drying fan 28 is provided on the inner surface side of the case where the ventilation port 21d is provided. When this fan 28 operates, the air in the internal space of the case body 11 is discharged to the outside. When a smartphone is set inside as described later, the smartphone can be dried. Also, the operation of this fan 28 is, for example, interlocked with the operation of the first ultraviolet light emitting unit 29 and the second ultraviolet light emitting unit 42, and when the first ultraviolet light emitting unit 29 and the second ultraviolet light emitting unit 42 are lit, the fan 28 also operates and stops when they go out. By doing so, an independent switch for the fan 28 becomes unnecessary, and during the disinfection and sterilization process when the first ultraviolet light emitting unit 29 and the second ultraviolet light emitting unit 42 emit light, the fan 28 can also operate to achieve drying.

[0032] The lateral width of the drawer part 12 housed in the case body 11 is shorter than the lateral width of the internal space of the case body 11 by a predetermined length, and a predetermined space is secured between the outside of the side surface 12c of the drawer part 12 and the inside of the side surface (the side surface 21c of the first case 21) of the case body 11. When the drawer part 12 is housed in the case body 11 and is in the locked state, the fan 28 etc. enters and fits into this space. When the drawer part 12 is housed in the case body 11 and disinfection treatment etc. is performed, the air in the internal space of the drawer part 12 is exhausted to the outside through the gap formed between the inner peripheral surface of the case body 11, and the drying of the smartphone 1 can be efficiently achieved. Also, an opening may be provided at a predetermined position on the side surface 12c of the drawer part 12, and the air in the drawer part 12 may be exhausted to the outside through the opening. When providing the opening, the installation position is preferably a position facing the fan 28 when the drawer part 12 is housed.

[0033] The inner bottom surface 22a of the second case 22 is provided with two rail parts 23 extending along the longitudinal direction. The heights of the two rail parts 23 are made equal, and the drawer part 12 is configured to be placed on the rail parts 23. That is, the drawer part 12 moves within the case body 11 while being supported by the rail parts 23. The contact resistance between the drawer part 12 and the inner bottom surface of the second case 22 is reduced, and the drawer part 12 can be inserted and set or pulled out of the case body 11 with a small force. Also, a space is left between the inner bottom surface 22a of the second case 22 and the lower surface of the drawer part 12 by the height of the rail parts 23.

[0034] A locking projection 24 is provided on the inner rear surface 22b of the second case 22. On the other hand, a locking mechanism portion 20 is provided at a position on the rear surface 12b of the drawer portion 12 that faces the locking projection 24. The locking mechanism portion 20 is a mechanism that can be connected to and detached from the locking projection 24. As the drawer portion 12 is inserted, the locking mechanism portion 20 comes into contact with the locking projection 24, and when it is further pushed in while in this state, it is connected to the locking projection 24 and locked. The locking mechanism portion 20 has a built-in spring, and when the drawer portion 12 is pushed in and connected to the locking projection 24, the drawer portion 12 is pushed back slightly forward. In this locked state, the drawer portion 12 remains in the case body 11 in the pushed-back state. And the front surface 12a of the drawer portion 12 in this locked state holds the state of closing the opening 11a. On the other hand, when the front surface 12a is pushed into the case body 11 in the locked state, the drawer portion 12 is pushed in by a predetermined amount due to the elastic deformation of the spring, and the locking of the locking projection 24 of the locking mechanism portion 20 is released. After that, by moving the drawer portion 12 forward as it is, it can be projected outside the case body 11, and further, the entire drawer portion 12 can be taken out of the case body 11.

[0035] The above-described second ultraviolet irradiation unit 14 is installed in a region sandwiched between a pair of rail portions 23 with the surface provided with the second ultraviolet light emitting portion 42 facing upward. A space is secured in the region sandwiched between the pair of rail portions 23 by the height of the rail portions 23, and by arranging the second ultraviolet irradiation unit 14 in this space, the drawer portion 12 can reciprocate without interfering with the second ultraviolet irradiation unit 14.

[0036] The smartphone stand 15 has a substantially flat rectangular shape, and the dimensional shape of the outer peripheral edge in plan view is made substantially the same as or smaller than the bottom surface of the inner peripheral surface of the drawer portion 12. In this embodiment, it is made slightly smaller. The smartphone stand 15 includes a substantially rectangular pedestal portion 15a and a peripheral wall portion 15b extending downward from the outer peripheral edge of the pedestal portion 15a. And, concave cutout portions 15c are formed at the centers of both short sides of the smartphone stand 15. This concave cutout portion 15c is arranged so as not to interfere with the convex portion of the lock mechanism portion 20 when the smartphone stand 15 is set in the drawer portion 12. Further, the upper surface of the pedestal portion 15a is provided with a slightly smaller rectangular shallow recess 15d. Therefore, most of the upper surface of the pedestal portion 15a becomes the part of the recess 15d, and the outer shape has a portion that is one step higher on the outside of the peripheral edge of the recess 15d. The dimensional shape of the recess 15d in plan view may be made equal to or slightly larger than the outer dimensions of a relatively small-sized smartphone, for example. By doing so, a smartphone of such a relatively small size fits within the recess 15d and is roughly positioned. On the other hand, a smartphone 1 of a larger size is supported by a portion that is one step higher than the recess 15d. Further, protrusions 15e are provided near both short sides on this portion that is one step higher, so as to suppress the movement of the smartphone 1 supported by the portion that is one step higher on the upper surface of the pedestal portion 15a. Also, two through holes 34 are formed in the recess 15d at a predetermined interval on a line passing through the center in the short-side direction.

[0037] And, in a state where the drawer portion 12 is pushed in and housed in the case body 11, a through hole 35 penetrating vertically is formed in a portion of the inner bottom surface 12f of the drawer portion 12 that faces the second ultraviolet light emitting portion 42. Similarly, in a state where the smartphone stand 15 is mounted in the drawer portion 12, through holes 34 are respectively formed at positions facing the through holes 35 provided in the drawer portion 12 of the smartphone stand 15.

[0038] In addition, the smartphone stand 15 is made of a material that transmits ultraviolet rays. For example, it may be formed using a transparent member, such as an acrylic plate. Therefore, the ultraviolet rays emitted from the second ultraviolet light emitting unit 42 that pass through the through hole 34 reach directly above the smartphone stand 15 as they are. Also, the ultraviolet rays irradiated on the part of the smartphone stand 15 where members such as around the through hole 34 exist pass through the inside of the smartphone stand 15 and reach above the smartphone stand 15.

[0039] In actual use, for example, as shown in Fig. 1(a), the smartphone stand 15 is mounted on the drawer part 12 with the pedestal part 15a of the smartphone stand 15 facing up. In that state, the smartphone 1 is set on the pedestal part 15a of the smartphone stand 15, and then the drawer part 12 is housed in the case body 11 as it is.

[0040] Then, as shown in Fig. 3, one surface of the smartphone 1, for example, the surface side having the screen, faces the first ultraviolet light emitting unit 29. At this time, the irradiation area of the first ultraviolet light emitting unit 29 spreads radially as shown by the two-dot chain line in Fig. 3, and the ultraviolet rays emitted from the first ultraviolet light emitting unit 29 are irradiated over the entire surface of the smartphone 1 set on the smartphone stand 15, and it is configured to perform disinfection, sterilization, etc. That is, considering the standard thickness of the smartphone 1, the dimensions such as the height inside the case body 11 and the height of the smartphone stand 15 are determined so that the ultraviolet rays from the first ultraviolet light emitting unit 29 irradiate approximately the entire surface of the smartphone 1 in the state where the smartphone 1 is placed on the pedestal part 15a of the smartphone stand 15.

[0041] Then, the ultraviolet rays emitted from the second ultraviolet light emitting unit 42 pass through the through hole 34 of the smartphone stand 15 and irradiate a predetermined area on the inner surface of the smartphone 1. Therefore, the irradiated part is sterilized or the like by the same action as in the first embodiment. And in this embodiment, since a space is formed between the upper side of the smartphone stand 15 and the smartphone 1, the range irradiated with ultraviolet rays is wider than the through hole 34. Further, in this embodiment, since the smartphone stand 15 is formed of a member that transmits ultraviolet rays, the entire inner surface side of the smartphone 1 is irradiated with ultraviolet rays. Therefore, even if a part of the ultraviolet rays is absorbed when passing through the smartphone stand 15, a certain sterilization and disinfection effect is exhibited by the many ultraviolet rays that are transmitted without being absorbed.

[0042] Furthermore, in this embodiment, as shown by the two-dot chain line in FIG. 3, the height of the smartphone stand 15 is configured such that the ultraviolet rays emitted from the second ultraviolet light emitting unit 42 that spreads radially irradiate almost the entire other surface of the smartphone 1 set on the smartphone stand 15, for example, the back surface without a screen, and sterilization and disinfection are performed.

[0043] Also, by forming the smartphone stand 15 of a member that transmits ultraviolet rays, even if the area of the opening through which the ultraviolet rays directly pass is reduced, for example, by reducing the diameter of the through hole 34, the entire back surface side of the smartphone 1 can be irradiated with ultraviolet rays, and sterilization and disinfection can be performed. And the strength of the smartphone stand 15 can be increased, and even for a heavy smartphone, for example, the smartphone stand 15 can firmly support it.

[0044] In this way, both sides of the smartphone 1 are irradiated with ultraviolet rays emitted from both the first ultraviolet light emitting unit 29 and the second ultraviolet light emitting unit 42 at the same time, and sterilization and disinfection are performed. And if the ultraviolet rays are irradiated by lighting for a predetermined time and the sterilization process is performed, the drawer unit 12 is taken out from the case body 11 to expose the smartphone 1. The user can easily lift the smartphone 1 and take it out from the drawer unit 12 by putting a finger into the concave notch 15c of the smartphone stand 15 located on the front side of the drawer unit 12, for example.

[0045] In the above-described embodiment, the second ultraviolet light emitting unit 42 has the same rating as the first ultraviolet light emitting unit 29. However, the present invention is not limited to this. For example, by using ultraviolet light with a wavelength of 165 nm, ozone can be generated. By utilizing this ozone, deodorization and the like of the smartphone 1 can be achieved. Alternatively, conversely, ozone may be generated in the ultraviolet light emitted from the first ultraviolet light emitting unit 29. Further, instead of such replacement, for example, in addition to the first ultraviolet light emitting unit 29 and the second ultraviolet light emitting unit 42 in the above-described embodiment, an LED for emitting ultraviolet light for generating ozone may be installed at an appropriate location such as an intermediate position.

[0046] Also, in each of the above-described embodiments, the fan 28 is attached to the side surface of the case body 11. However, it may be attached to various locations such as the bottom surface of the case body 11. The fan 28 is for drying the smartphone 1. In particular, the inner surface of the smartphone 1 may become moist along with the user's breathing and the like. Therefore, when the smartphone stand 15 is convex upward and the outer surface of the smartphone 1 is upward for disinfection and the like, if the fan 28 is arranged on the bottom surface side, the inner surface side of the smartphone 1 can be efficiently dried.

[0047] The drawer portion 12 is preferably made detachable from the case body 11. By doing so, the entire drawer portion 12 is exposed to the outside, so it becomes easier to remove the smartphone 1 from the case body 11.

[0048] Furthermore, as described above, since the smartphone stand 15 is detachable from the drawer section 12, it is possible to prepare a stand member of a shape suitable for placing items other than smartphones, and then change it into the smartphone stand 15 so that the stand member can be attached to the case body 11. The stand member attached to the inside of the drawer section 12 is preferably sized and shaped so that when the drawer section 12 is stored in the case body 11 with a predetermined item placed thereon, ultraviolet light is irradiated from above and below the entire surface of the item. In this way, it is possible to sterilize items other than smartphones as well.

[0049] Various aspects of the present invention have been described above using embodiments and modifications. However, it should be noted that these embodiments and descriptions are provided to aid in understanding the present invention, and are not intended to limit the scope of the present invention. The scope of the present invention is not limited to the structures and manufacturing methods explicitly described in the specification, but also includes combinations of various aspects of the present invention disclosed herein.
