Description

The present invention relates to a device charging tray and fixture.

In recent years, classes in schools and other classrooms have seen an increase in the number of students using portable electronic devices such as laptops (personal computers) and tablet devices. When not in use, these devices are generally stored together in storage fixtures such as lockers, and when needed, students typically remove them from the storage fixtures and use them on their desks. Furthermore, when not in use, the batteries of these devices are charged while stored in the storage fixtures. For this reason, a variety of storage fixtures equipped with electronic device charging functions are now being offered.

For example, Patent Document 1 discloses a configuration comprising a storage fixture main body with a storage space capable of storing items, a power supply unit provided in the storage fixture main body, and a box-shaped tray device inside which are placed multiple electronic devices connected to the power supply unit while stored in the storage space.
However, in the configuration disclosed in Patent Document 1, multiple electronic devices stored in the storage fixture must be connected to the power supply unit with individual wiring, which means that when storing multiple electronic devices in the storage fixture or removing multiple electronic devices from the storage fixture, the wiring must be attached and detached for each electronic device.

In response to this, for example, Patent Document 2 discloses a configuration that includes a power transmission sheet that is attached to the shelf (storage section) of a storage fixture (cabinet) and has a built-in power transmission coil, and a power receiving sheet that is attached to an electronic device and has a built-in power receiving coil. In this configuration, by attaching the power receiving sheet to the electronic device, simply placing the electronic device and power receiving sheet on the power transmission sheet allows power to be supplied contactlessly between the power transmission coil and power receiving coil. This eliminates the need to connect and disconnect wiring to the electronic device every time the electronic device is taken in or out of the storage device.

Patent No. 6508810 Japanese Patent Application Laid-Open No. 2018-201273

However, in the configuration described in Patent Document 2, in order to reliably supply power from the power transmission sheet to the power receiving sheet, it is necessary to place the electronic device equipped with the power receiving sheet on the power transmission sheet, with the power receiving sheet and the power transmission sheet facing each other in the vertical direction. In other words, the electronic device is placed flat on the power transmission sheet attached to the shelf. This makes it difficult to effectively utilize the space within the fixture to store a large number of electronic devices, and the number of electronic devices that can be stored is limited.
The present invention aims to provide an equipment charging tray and a fixture that can provide contactless power supply to electronic devices while making effective use of the space in the fixture.

In order to achieve the above-mentioned objectives, one aspect of the present invention provides a portable device charging tray that can be placed on an item placement surface provided on a fixture, and includes: a base portion supported on the item placement surface; a device support portion provided on the base portion, extending obliquely upward relative to the item placement surface and capable of supporting a first surface of an electronic device; a power supply portion provided on the device support portion that provides contactless power supply to a power receiving portion provided on the electronic device; and a power supply connector that is detachably connected to a power supply portion provided on the fixture and that supplies power from the power supply portion to the power supply portion when connected to the power supply portion.

In this way, the first surface of the electronic device is supported by the device support section, which extends obliquely upward from the base section. This allows the power supply section provided on the device support section to reliably supply power wirelessly to the power receiving section of the electronic device. Furthermore, by supporting the electronic device at an angle on the device support section, the area occupied by the electronic device on the item placement surface can be kept small. By placing the base section of such a device charging tray on the item placement surface of the fixture and connecting the power supply connector to the fixture's power supply section, it is possible to effectively use the space in the fixture while supplying power wirelessly to the electronic device.

In one aspect of the device charging tray of the present invention, a restraint section may be further provided that restrains movement of the electronic device in a direction opposite to the inclination direction of the device support section when the first surface is supported by the device support section.
According to this configuration, the restraining portion restrains the electronic device from moving in the direction opposite to the tilt direction of the device support portion, which makes it easier for the first surface of the electronic device to come into close contact with the device support portion. This keeps the first surface of the electronic device aligned with the device support portion, ensuring contactless power supply.

In one aspect of the present invention, the device charging tray includes a plurality of device support portions provided at intervals along the article placing surface.
According to this configuration, by providing a plurality of device support sections, the device charging tray can efficiently accommodate a greater number of electronic devices.

In one embodiment of the present invention, in an equipment charging tray, a pair of equipment support portions arranged opposite each other in a direction along the item loading surface may be inclined in a direction away from each other as they move from bottom to top, and the restraint portion may protrude upward from a portion of the base portion located between the pair of equipment support portions.
According to this configuration, the electronic devices supported by the pair of opposing device support parts are arranged in a V-shape. The lower end of the electronic device abuts against the restraining part that protrudes upward from the base part, thereby restraining movement in the direction opposite to the tilt direction of the device support parts, and maintaining a state in which the first surface of the electronic device is aligned with the device support parts.

In the device charging tray according to one aspect of the present invention, the device support portions may be inclined in the same direction.
According to this configuration, by having the multiple device support sections incline to the same side, it is possible to accommodate more electronic devices in the device charging tray and perform contactless power supply within a limited space.

In one aspect of the device charging tray of the present invention, the tray may further include an device pressing portion that is displaceable in a direction toward or away from the device support portion and supports the electronic device from a second surface side of the electronic device facing opposite to the first surface.
With this configuration, by supporting the electronic device from the second surface side with the device pressing portion, the first surface of the electronic device can be reliably pressed against the device support portion on which the power supply portion is provided. This ensures contactless power supply to the electronic device. Furthermore, when the device charging tray is carried with the electronic device stored on it, shaking of the electronic device on the device charging tray can be prevented.

In one aspect of the device charging tray of the present invention, the device pressing portion may be arranged at a distance from the device support portion in a direction along the item loading surface, and may include an opposing wall portion extending upward from the base portion, and a plurality of elastic pressing elements extending from the opposing wall portion toward the device support portion, being elastically deformable, and pressing the electronic device toward the device support portion.
According to this configuration, the electronic device is housed between the device support part and the multiple elastic pressers. By pressing the electronic device toward the device support part with the multiple elastic pressers, the first surface of the electronic device is pressed against the device support part on which the power supply part is provided, thereby ensuring contactless power supply.

In one aspect of the device charging tray of the present invention, the device pressing portion may be arranged at a distance from the device support portion in a direction along the item loading surface, and may include an opposing wall portion extending upward from the base portion, a contact panel that contacts the second surface of the electronic device when the electronic device is supported on the device support portion, and a biasing member having one end supported by the opposing wall portion and the other end connected to the contact panel, and biasing the contact panel toward the electronic device.
With this configuration, when the electronic device is inserted between the device support part and the contact panel, the contact panel is biased toward the electronic device by the biasing member, pressing the electronic device toward the device support part, thereby pressing the first surface of the electronic device against the device support part on which the power supply part is provided, and ensuring contactless power supply.

A fixture according to one aspect of the present invention comprises an article placement surface on which the above-described device charging tray can be placed, and a power supply unit detachably connected to the power supply connector.
According to this configuration, by placing the device charging tray on the item placement surface of the fixture and connecting the power supply connector to the power supply unit of the fixture, it is possible to effectively utilize the space of the fixture while providing contactless power supply to electronic devices.

One aspect of the present invention makes it possible to provide contactless power supply to electronic devices while making effective use of fixture space.

Hereinafter, with reference to the accompanying drawings, embodiments for implementing the device charging tray and fixture of the present invention will be described. However, the present invention is not limited to these embodiments.

(First embodiment)
FIG. 1 is a side cross-sectional view showing a state in which an equipment charging tray 10A according to an embodiment of the present invention is placed on an article placement surface 7 of a fixture 1.
1, the fixture 1 is installed in various facilities such as classrooms. The fixture 1 can store multiple portable electronic devices 100 in a single unit by mounting them on a device charging tray 10A, and can also charge the stored electronic devices 100. The fixture 1 includes a bottom panel 2, a pair of side panels 3, a top panel 4, a back panel 5, and shelf panels 6.

The bottom plate 2 is rectangular in plan view and is arranged along a horizontal plane parallel to the floor (not shown). The bottom plate 2 may be supported by multiple legs (not shown) or multiple casters (not shown) that stand up from the floor. The bottom plate 2 may be placed directly on the floor. A pair of side plates 3 extend upward from both ends of the bottom plate 2 in the width direction (the direction perpendicular to the paper surface in Figure 1). The top plate 4 is rectangular in plan view and is arranged along a horizontal plane. The top plate 4 is installed between the upper ends of the pair of side plates 3. The back plate 5 is located at the rear end of the fixture 1 (to the right in Figure 1) and is installed between the rear ends of the bottom plate 2, side plates 3, and top plate 4. Such fixture 1 has an opening 1a that opens forward. The opening 1a is provided with an openable door 9. Note that fixture 1 may also be an open type without a door 9. In fixture 1, it is desirable that at least the bottom plate 2, side plates 3, top plate 4, back plate 5, and door 9 are made of metal such as steel plate, stainless steel plate, or aluminum plate. This prevents unwanted radiation generated within fixture 1 from radiating outside fixture 1. It also prevents heat generated within fixture 1 from radiating outside fixture 1.

One or more shelf boards 6 are provided between the bottom board 2 and the top board 4. In this embodiment, for example, two shelf boards 6 are provided. Both ends of the shelf board 6 are supported by the pair of side boards 3.
An article placement surface 7 on which an article can be placed is formed on the top surface of the bottom plate 2 and each shelf plate 6. The top surface of the top plate 4 can also be used as the article placement surface 7.

The device charging tray 10A is portable. It is made of, for example, resin. It may also be made of, for example, nonwoven fabric, wood, paper such as vulcanized fiber, or non-metallic materials such as Senamic. The device charging tray 10A can be inserted into and removed from the fixture 1 through the opening 1a. The device charging tray 10A can be placed on the item placement surface 7 of the fixture 1. The device charging tray 10A stores multiple electronic devices 100 and provides contactless power to each electronic device 100. The electronic devices 100 are thin, portable devices such as laptops and tablet terminals that can operate on power supplied from a battery.

Fig. 2 is a perspective view of the device charging tray 10A, and Fig. 3 is a cross-sectional view of the device charging tray 10A as seen from the front.
As shown in FIGS. 1 to 3, the device charging tray 10A has a base portion 11A, a pair of side walls 12, and a pair of end walls 13. The base portion 11A forms the bottom surface of the device charging tray 10A. The base portion 11A is capable of being placed on the article placement surface 7 (see FIG. 2). The pair of side walls 12 extend upward from both ends of the base portion 11A in the width direction (horizontal direction Dh). The pair of end walls 13 extend upward from both ends of the base portion 11A in the front-rear direction. The device charging tray 10A, which includes the base portion 11A, the pair of side walls 12, and the pair of end walls 13, is formed into a box shape that opens upward.

As shown in FIG. 3, the device charging tray 10A further includes a device support section 20A, a restraining section 22, a power supply section 30, and a power supply connector 50 (see FIG. 1).
The device support section 20A is capable of supporting a rear surface (first surface) 100r of the electronic device 100. A lower end section 100b of the electronic device 100, whose rear surface 100r is supported by the device support section 20A, is supported from below by the base section 11A. The electronic device 100 includes a power receiving section 101 having a power receiving coil that receives power via wireless power supply, and a battery that can be charged by the power received by the power receiving section 101. The electronic device 100 has the power receiving section 101 built in on the rear surface 100r side.

A plurality of device support sections 20A are provided at intervals in the horizontal direction Dh (e.g., the direction along the item placement surface 7). Each device support section 20A extends diagonally upward from the base section 11A in the horizontal direction Dh. Each device support section 20A may be inclined with respect to the horizontal direction Dh. In this embodiment, the inclination angle of each device support section 20A with respect to the horizontal direction Dh may be such that the center of gravity of the electronic device 100 is shifted outward in the horizontal direction Dh from the lower end of the electronic device 100, and is set, for example, in the range of 5° to 30°.

In this embodiment, a pair of device support sections 20A facing each other in the horizontal direction Dh constitutes an opposing support section 20H. Multiple pairs (e.g., three pairs) of opposing support sections 20H are arranged side by side in the horizontal direction Dh. The device support sections 20A constituting one opposing support section 20H are inclined away from each other. Therefore, the distance between the device support sections 20A constituting one opposing support section 20H gradually increases from bottom to top. In other words, the opposing support sections 20H are arranged in a V-shape when viewed from the front-to-back direction. Between adjacent opposing support sections 20H, the opposing device support sections 20A are inclined toward each other. Between adjacent opposing support sections 20H, the upper ends of the opposing device support sections 20A are connected by a connection section 21. Of the opposing support sections 20H located at both ends in the horizontal direction Dh, the outermost device support sections 20A also serve as a pair of side wall sections 12.

The restraining portion 22 is provided on the base portion 11A. In this embodiment, the restraining portion 22 is a portion located between a pair of device supports 20A that constitute one opposing support portion 20H, and protrudes upward from the base portion 11A. The lower end portion 100b of the electronic device 100, whose rear surface 100r is supported by the device support 20A, is supported from below by the base portion 11A. With the rear surface 100r supported by the device support 20A, the restraining portion 22 abuts against the lower end portion 100b of the electronic device 100 from the side opposite to the device support 20A. The restraining portion 22 restrains movement of the electronic device 100 in the direction opposite to the tilt direction of the device support 20A (the direction away from the device support 20A in the horizontal direction Dh).
The restraint section 22 is not limited in configuration as long as it can restrain the movement of the electronic device 100 in the direction opposite to the tilt direction of the device support section 20A, and may be, for example, a partition wall standing upright from the base section 11A, or a belt or band-like plate stretched between the pair of end wall sections 13. Furthermore, the restraint section 22 may be provided with an anti-slip portion with a high friction coefficient on the surface of the base section 11A.

The power supply unit 30 is provided on each device support 20A. The power supply unit 30 includes a power supply coil (not shown). The power supply unit 30 is provided on the side of each device support 20A opposite to the side supporting the rear surface 100r of the electronic device 100. The power supply unit 30 may be embedded in each device support 20A. The power supply coil (not shown) of the power supply unit 30 is provided to face the power receiving unit 101 provided on the rear surface 100r side of the electronic device 100 when the rear surface 100r of the electronic device 100 is supported on the device support 20A. The power supply unit 30 contactlessly supplies power to the power receiving unit 101 via a power supply connector 50 (described later).
In addition, even if the front surface 100f of the electronic device 100, which is opposite to the back surface 100r on which the power receiving unit 101 is provided, is facing the device support part 20A, the device support part 20A may support the front surface 100f side of the electronic device 100, as long as contactless power supply by the power supply part 30 is possible.

As shown in FIG. 1 , the power supply connector 50 is detachably connected to the power supply unit 8 provided on the fixture 1. The power supply connector 50 is provided, for example, at the lower end of the rear end wall portion 13. The power supply unit 8 is provided, for example, on each item placement surface 7. The power supply unit 8 is a connector receptacle for supplying power supplied from a power source, such as an external commercial power source, to the power supply unit 30. The power supply connector 50 is detachably connected to the power supply unit 8, for example, by the magnetic force of a magnet. The power supply unit 8 and the power supply connector 50 each have connection terminals (not shown) that are electrically connected to each other when connected. The power supply connector 50 is electrically connected to the power supply unit 30 via a power supply wiring 51. When connected to the power supply unit 8, the power supply connector 50 transmits power supplied from a power source, such as an external commercial power source, via the power supply unit 8 to the power supply unit 30 via the power supply wiring 51.

As shown in FIG. 3 , the device charging tray 10A described above stores electronic devices 100, such as laptop PCs and tablets, tilted along the device support sections 20A. The back surface 100r of the electronic device 100 is supported along the device support sections 20A. For example, when a user, such as a teacher or student, inserts the electronic device 100 diagonally from above along the device support sections 20A, the restraining section 22 acts as a stopper, and the electronic device 100 is supported with the back surface 100r aligned with the device support sections 20A. Furthermore, when a user inserts the electronic device 100 into the device charging tray 10A from directly above, the electronic device 100 tilts toward the device support sections 20A, starting from the restraining section 22, and the back surface 100r is supported along the device support sections 20A. In this way, regardless of how the electronic device 100 is inserted, the power receiving section 101 of the electronic device 100 and the power supply coil (not shown) of the power supply section 30 face each other closely.

As shown in FIG. 1, the device charging tray 10A containing the electronic device 100 is placed on the item placement surface 7, and the power supply connector 50 is connected to the power supply unit 8 provided on the item placement surface 7. Power is then supplied to the power supply unit 30 from a power source such as an external commercial power source via the power supply unit 8, the power supply connector 50, and the power supply wiring 51. As a result, the power supply unit 30 provides contactless power supply to the power receiving unit 101 of the electronic device 100.

Furthermore, the device charging tray 10A can be removed from the fixture 1 with the electronic device 100 still stored inside by disconnecting the power supply unit 8 from the power supply connector 50. The electronic device 100 can also be inserted into and removed from the device charging tray 10A outside the fixture 1.

In this manner, in this embodiment, the rear surface 100r of the electronic device 100 is supported by the device support portion 20A that extends obliquely upward from the base portion 11A.
With this configuration, the power supply unit 30 provided in the device support unit 20A can supply power contactlessly to the power receiving unit 101 of the electronic device 100. This eliminates the need to connect and disconnect wiring for charging each electronic device 100. Furthermore, by supporting the electronic device 100 at an angle on the device support unit 20A, the area occupied by one electronic device 100 on the article mounting surface 7 can be kept small.
Therefore, according to the device charging tray 10A and fixture 1 of this embodiment, by placing the base portion 11A of the device charging tray 10A on the item placement surface 7 of the fixture 1 and connecting the power supply connector 50 to the power supply portion 8 of the fixture 1, it is possible to effectively utilize the space of the fixture 1 while providing contactless power supply to the electronic device 100.
Furthermore, the device charging tray 10A is portable and equipped with a power supply connector 50, so that by disconnecting the power supply connector 50 from the power supply unit 8, the device can be carried with the electronic device 100 stored therein, thereby increasing convenience for users of the electronic device 100.
Furthermore, since the device support section 20A supports the electronic device 100 in an inclined state, it is possible to charge the electronic device 100 whether it is a notebook PC or a tablet PC, thereby increasing the versatility of the device charging tray 10A.

In this embodiment, the restraining portion 22 restrains the electronic device 100 from moving in the direction opposite to the tilt direction of the device support portion 20A.
According to this configuration, the rear surface 100r of the electronic device 100 can be easily brought into close contact with the device support part 20A. This allows the rear surface 100r of the electronic device 100 to be kept aligned with the device support part 20A, ensuring reliable contactless power supply.

In this embodiment, a configuration is provided in which a plurality of device support sections 20A are provided.
With this configuration, the device charging tray 10A can efficiently accommodate a larger number of electronic devices 100. Furthermore, the device charging tray 10A can be carried while storing multiple electronic devices 100, which increases convenience for the user.

In this embodiment, the distance between opposing device support parts 20A gradually increases from bottom to top. With this configuration, the electronic devices 100 supported by the paired device support parts 20A are arranged in a V-shape. The lower end parts 100b of the paired electronic devices 100 abut against the restraining parts 22 that protrude upward from the base part 11A. With this configuration, movement of the device support parts 20A in the direction opposite to the tilt direction is restrained, and the back surface 100r of the electronic device 100 is maintained in alignment with the device support parts 20A.

Second Embodiment
Next, a second embodiment of the device charging tray according to the present invention will be described. In the second embodiment described below, components common to the first embodiment will be denoted by the same reference numerals in the drawings and will not be described again.
FIG. 4 is a cross-sectional view of a device charging tray 10B according to a second embodiment of the present invention, as viewed from the front.
As shown in FIG. 4 , the device charging tray 10B in this embodiment includes a base portion 11B, a plurality of device support portions 20B, and a plurality of opposing wall portions 71.

The base portion 11B can be placed on the item placement surface 7 of the fixture 1. The device support portion 20B extends obliquely upward from the base portion 11B and can support the rear surface 100r of the electronic device 100. In this embodiment, the multiple device support portions 20B are each inclined upward to the same side of the horizontal direction Dh (to the right in Figure 4). In other words, the inclination directions of the multiple device support portions 20B are the same.

The multiple opposing wall portions 71 are arranged at intervals in the horizontal direction Dh relative to their respective equipment support portions 20B. Each opposing wall portion 71 extends upward from the base portion 11B approximately perpendicular to the horizontal direction Dh. As a result, the distance between each equipment support portion 20B and the opposing wall portion 71 gradually decreases from top to bottom. However, each opposing wall portion 71 may extend at an angle relative to the horizontal direction Dh.

In this configuration, the lower end of the opposing wall portion 71 serves as a restraint portion 22 that restrains the movement of the lower end portion 100b of the electronic device 100, whose back surface 100r is supported by the device support portion 20B, in the direction opposite to the tilt direction of the device support portion 20B.

In this embodiment, as with the first embodiment described above, by placing the base portion 11B of the device charging tray 10B on the item placement surface 7 of the fixture 1, it is possible to effectively utilize the space of the fixture 1 while providing contactless power supply to the electronic device 100.

In this embodiment, the device support sections 20B are configured to be inclined to the same side in the horizontal direction Dh.
With this configuration, it is possible to accommodate more electronic devices 100 in the device charging tray 10B within a limited space and perform contactless power supply.

(Third embodiment)
Next, a third embodiment of the device charging tray according to the present invention will be described. In the third embodiment described below, components common to the first and second embodiments will be denoted by the same reference numerals in the drawings and will not be described again.
FIG. 5 is a cross-sectional view of a device charging tray 10C according to a third embodiment of the present invention, as viewed from the front.
5, the device charging tray 10C of this embodiment further includes a device pressing portion 70C in addition to the configuration shown in the second embodiment. The device pressing portion 70C is provided so as to be displaceable toward or away from the device support portion 20B, and supports the electronic device 100 from the front surface (second surface) 100f of the electronic device 100, which faces away from the back surface 100r.

In this embodiment, the device pressing unit 70C includes an opposing wall portion 71 and a pressing member main body 72C that presses the electronic device 100 toward the device support portion 20B. The pressing member main body 72C extends from the opposing wall portion 71 toward the device support portion 20B and includes multiple elastic pressing elements 73 that are elastically deformable. The multiple elastic pressing elements 73 protrude gradually smaller from the opposing wall portion 71 from the upper elastic pressing element 73 toward the lower elastic pressing element 73. A gap is formed between the tips of the multiple elastic pressing elements 73 and the device support portion 20B. This gap may be slightly narrower than the thickness of the electronic device 100, or may be equal to or greater than the thickness of the electronic device 100.

When the electronic device 100 is inserted between the device support part 20B and the multiple elastic pressers 73, the elastic pressers 73 elastically deform and collapse, causing the electronic device 100 to slide downward. When the bottom end 100b of the electronic device 100 reaches the base part 11B and the electronic device 100 is released, the restoring force of the elastic pressers 73 presses the electronic device 100 toward the device support part 20B.

In this embodiment, as with the first and second embodiments, the base portion 11B of the device charging tray 10C is placed on the item placement surface 7 of the fixture 1, thereby making effective use of the space in the fixture 1 while providing contactless power supply to the electronic device 100.

In this embodiment, the electronic device 100 is supported from the front surface 100f side by the device pressing portion 70C.
With this configuration, the rear surface 100r of the electronic device 100 can be reliably pressed against the device support portion 20B on which the power supply portion 30 is provided. This ensures that power can be supplied to the electronic device 100 without contact. Furthermore, when the device charging tray 10C, 10D is carried with the electronic device 100 stored on the device charging tray 10C, 10D, shaking of the electronic device 100 on the device charging tray 10C, 10D can be prevented.

In this embodiment, the device pressing portion 70</b>C is configured to include an opposing wall portion 71 and a plurality of elastic pressing elements 73 .
According to this configuration, electronic device 100 is inserted between device support part 20B and the tips of multiple elastic pressers 73 extending from opposing wall part 71 toward device support part 20B, and the tips of multiple elastic pressers 73 abut against electronic device 100, thereby pressing electronic device 100 toward device support part 20B. This allows rear surface 100r of electronic device 100 to be pressed against device support part 20B on which power supply unit 30 is provided.

(Fourth embodiment)
Next, a fourth embodiment of the device charging tray according to the present invention will be described. In the fourth embodiment described below, components common to the first to third embodiments will be denoted by the same reference numerals in the drawings and will not be described again.
FIG. 6 is a cross-sectional view of a device charging tray 10D according to a fourth embodiment of the present invention, as viewed from the front.
As shown in FIG. 6, the device charging tray 10D of this embodiment includes a device pressing portion 70D.
The device pressing portion 70D in this embodiment includes an opposing wall portion 71 and a pressing member main body 72D that is provided on the opposing wall portion 71 and presses the electronic device 100 toward the device support portion 20B. The pressing member main body 72D includes a contact panel 75 and a plurality of biasing members 77.

The contact panel 75 is plate-shaped and comes into contact with the front surface 100f of the electronic device 100, whose back surface 100r is supported on the device support portion 20D. One end of the biasing member 77 is supported by the opposing wall portion 71, and the other end is connected to the contact panel 75. The biasing member 77 is made of, for example, a coil spring, and biases the contact panel 75 toward the device support portion 20B (the electronic device 100). The multiple biasing members 77 are arranged so that the spring length (natural length) increases from bottom to top, so that the contact panel 75 can be supported in a state aligned with the inclined device support portion 20B.
In addition, the contact panel 75 may be made to protrude above the equipment support portion 20D, and when the electronic device 100 is inserted between the contact panel 75 and the equipment support portion 20D, the gap between the contact panel 75 and the equipment support portion 20D can be widened by using the lower end portion 100b of the electronic device 100 to push the upper end portion of the contact panel 75 in a direction away from the equipment support portion 20D.

In this embodiment, as with the first to third embodiments described above, the base portion 11B of the device charging tray 10D is placed on the item placement surface 7 of the fixture 1, thereby making effective use of the space in the fixture 1 while providing contactless power supply to the electronic device 100.

In this embodiment, the device pressing portion 70D is configured to press the electronic device 100 toward the device support portion 20B.
With this configuration, the rear surface 100r of the electronic device 100 can be reliably pressed against the device support portion 20B on which the power supply portion 30 is provided. This ensures that power can be supplied to the electronic device 100 without contact. Furthermore, when the device charging tray 10D, 10D is carried with the electronic device 100 stored on the device charging tray 10D, 10D, shaking of the electronic device 100 on the device charging tray 10D, 10D can be prevented.

In this embodiment, the device pressing portion 70</b>D includes a contact panel 75 and a biasing member 77 .
With this configuration, when electronic device 100 is inserted between device support part 20D and contact panel 75, the gap between contact panel 75 and device support part 20D is widened, causing elastic (compressive) deformation of biasing member 77. When the user releases electronic device 100 when the lower end of electronic device 100 reaches base part 11B, biasing member 77 returns to its original shape, pressing electronic device 100 toward device support part 20D via contact panel 75. This allows rear surface 100r of electronic device 100 to be pressed against device support part 20D on which power supply part 30 is provided, ensuring contactless power supply.

(Other embodiments)
FIG. 7 is a cross-sectional view showing a main part of device charging trays 10A to 10D according to modifications of the first to fourth embodiments of the present invention.
As shown in Figure 7, the restraint portion 22E provided at the bottom of the equipment support portion 20B may be configured to be formed in a stepped shape in which the distance in the horizontal direction Dh from the equipment support portion 20B gradually increases from top to bottom.

Specifically, the restraint section 22E comprises a restraint section first bottom surface 221 extending from the lower end of the equipment support section 20B perpendicular to the equipment support section 20B; a restraint section first opposing surface 222 arranged at a distance D1 from the equipment support section 20B in a direction along the restraint section first bottom surface 221 and extending diagonally upward perpendicular to the restraint section first bottom surface 221; a restraint section second bottom surface 223 extending from the upper end of the restraint section first opposing surface 222 perpendicular to the restraint section first opposing surface 222; and a restraint section second opposing surface 224 arranged at a distance D2 in the horizontal direction Dh from the equipment support section 20A and extending diagonally upward perpendicular to the restraint section second bottom surface 223.

In this configuration, when the thickness of the electronic device 100 stored in the device charging tray 10A in the direction connecting the rear surface 100r and the front surface 100f of the electronic device 100 is smaller than the distance D1, the lower end 100b of the electronic device 100 is supported by the first restraining portion bottom surface 221 between the device support portion 20A and the first restraining portion opposing surface 222. Furthermore, when the thickness of the electronic device 100 stored in the device charging tray 10A is larger than the distance D1 and smaller than the distance D2, the lower end 100b of the electronic device 100 is supported by the second restraining portion bottom surface 223 between the device support portion 20A and the second restraining portion opposing surface 224.

With this configuration, even if there are multiple thicknesses of the electronic device 100 stored in the device charging tray 10A in the direction connecting the back surface 100r and the front surface 100f, the movement of the bottom end 100b of the electronic device 100 can be restrained by the restraint portion 22E.

Although the preferred embodiments of the present invention have been described above, the present invention is not limited to these embodiments. Addition, omission, substitution, and other modifications of the configuration are possible without departing from the spirit of the present invention. The present invention is not limited by the above description, but is limited only by the appended claims.
For example, in the above-described embodiment, the fixture 1 has a storage shelf-like configuration with shelves 6, but this is not limited thereto. The fixture 1 may have a desk-like or counter-like configuration, for example, as long as it has an item placement surface 7 on which the device charging tray 10A can be placed.

In the above-described embodiment, the device charging trays 10A-10D include base portions 11A and 11B, a pair of side walls 12, and a pair of end walls 13. However, this is not limiting. For example, the front end wall 13 may be omitted, and the device charging trays 10A-10D may be configured to open forward as well. This allows the electronic device 100 to be inserted or removed forward while the device charging trays 10A-10D are placed on the item mounting surface 7.
Furthermore, as shown in Figure 8, the device charging tray 10E may not be box-shaped and open upward, but may be configured to include a base portion 11E, a device support portion 20E, a restraint portion 22F, and a support portion 28 that supports the device support portion 20E.

In the third and fourth embodiments described above, the pressing member bodies 72C and 72D are provided on the opposing wall 71, but this is not limiting. For example, the pressing member bodies that exert a pressing force to press the electronic device 100 toward the device support 20B may be provided separately from the opposing wall 71. In this case, after the rear surface 100r of the electronic device 100 is tilted along the device support 20A, the pressing member bodies may be inserted between the front surface 100f of the electronic device 100 and the opposing wall 71. Such pressing member bodies may be, for example, sponge-like, brush-like, or an outer bag filled with a large number of granular materials.
In the above-described embodiment, the base portion functions as the bottom wall of the device charging tray, but the present invention is not limited to this configuration. The base portion may function as a side wall of the device charging tray as long as it is supported by the item mounting surface 7. In other words, the device charging tray may be configured such that the device support portion is bridged between a pair of base portions supported by the item mounting surface 7.
In the above-described embodiment, the device charging tray has a restraining portion, but the restraining portion is not a required component. The device may also have an anti-slip member to prevent misalignment between the device and the device charging tray.
In addition, within the scope of the spirit of the present invention, it is possible to replace the components in the above-described embodiments with well-known components as appropriate, and the above-described modified examples may be combined as appropriate.
