The detection plate 5 is a plate body with the front-rear direction being the thickness direction, and is attached to the rear portion of the mounting plate 4. Further, each partition plate 6 is a plate body with the left-right direction being the thickness direction, and is installed at predetermined intervals in the left-right direction on the front side of the sliding range of the detection plate 5. In the storage portion 3, an opening is provided at the front side of the box body 2, and the space surrounded by the adjacent partition plates 6, 6 (at the left and right ends of the mounting plate 4, the partition plates 6 located at the left and right ends and the side plates of the box body 2), the mounting plate 4, the detection plate 5, and the top plate of the box body 2 is a device storage portion 7 capable of storing one tablet terminal 50, and a plurality of such device storage portions 7 are arranged in parallel in the left-right direction. An iron plate 8 is attached to each partition plate 6, so that when charging the tablet terminal 50 stored in a predetermined device storage portion 7, the power transmission coil 20 installed in the device storage portion 7 does not affect the tablet terminal 50 stored in the adjacent device storage portion 7.

[0012] On the one hand, the charging mechanism includes an electric wire 19 disposed below the mounting plate 4 in the box body 2, and a plurality of power transmission coils 20, 20... electrically connected to the electric wire 19. The power transmission coils 20, 20... are provided corresponding to the device storage portions 7, 7..., and the tablet terminal 50 (tablet terminal 50 with a built-in predetermined power reception coil) stored in the corresponding device storage portion 7 can be charged non - contact by electromagnetic induction between the power transmission coil 20 and the power reception coil. The electric wire 19 is connected to a power supply unit (an element of the charging mechanism, for example, a power plug or a power outlet) (not shown) provided on the box body 2, and commercial power is supplied to the power transmission coils 20, 20... through the power supply unit.

[0013] Here, the adjustment structure of the vertical height and the adjustment structure of the front - rear depth of the device storage portion 7, which is the main part of the charging device 1, will be described. First, the adjustment structure for the vertical height of the equipment storage section 7 will be described. At the front end of the inner surface of the side plate of the box body 2, a first guide groove 9 extending vertically along the front edge of the side plate is engraved. Also, on the inner surface of the side plate of the box body 2, at a position behind the first guide groove 9 by the same distance as the front-back length of the mounting plate 4, a second guide groove 10 extending vertically is engraved. Further, on the front surface of the side plate of the box body 2 (particularly the front surface of the left side plate), an adjustment hole 11 formed in a long hole shape extending vertically is provided, and the adjustment hole 11 penetrates into the first guide groove 9. On the other hand, at the four corners of the mounting plate 4 (the left and right ends of the front edge and the left and right ends of the rear edge), guide protrusions 12, 12... protruding outward to the left and right are provided respectively. The front guide protrusion 12 can be fitted into the first guide groove 9, and the rear guide protrusion 12 can be fitted into the second guide groove 10 respectively. Such a mounting plate 4 is installed in the box body 2 by screwing an adjustment screw 13 into the front surface through the adjustment hole 11 in a state where the guide protrusions 12, 12... are fitted into the corresponding guide grooves 9, 10 respectively. Then, by sliding the mounting plate 4 in the vertical direction within the range of the vertical length of the adjustment hole 11 and changing the position of the adjustment screw 13 in the adjustment hole 11, that is, the screwing position by the adjustment screw 13, the installation height of the mounting plate 4 with respect to the box body 2, and thus the vertical height of the equipment storage section 7 can be adjusted. Note that a plurality of slits 14, 14... are provided in the mounting plate 4 for protruding each power transmission coil 20 into the corresponding equipment storage section 7.

[0014] Next, the adjustment structure for the front-to-back depth of the device storage section 7 will be described. At the lower left and right corners of the detection plate 5, adjustment pieces 15, 15 that protrude forward are provided. Each adjustment piece 15 has an adjustment slit 16 in the shape of a long hole that extends in the front-to-back direction. Such a detection plate 5 is installed on the mounting plate 4 by screwing an adjustment screw 17 into the upper surface of the mounting plate 4 through the adjustment slit 16. Then, by sliding the detection plate 5 in the front-to-back direction within the range of the front-to-back length of the adjustment slit 16 and relatively changing the position of the adjustment screw 17 within the adjustment slit 16, the front-to-back position of the detection plate 5 on the mounting plate 4, and thus the front-to-back depth of the device storage section 7, can be adjusted. Note that on the front surface of the detection plate 5, a switch 18 for detecting the tablet terminal 50 stored in the device storage section 7 is provided corresponding to each device storage section 7.

[0015] According to the charging device 1 having the above configuration, the device storage part 7 opens to the front side of the box main body 2, and can store the tablet terminal 50 from the front side of the box main body 2, and a plurality of them are provided in the left - right direction on the mounting plate 4 installed in the box main body 2. By changing the installation position of the mounting plate 4 with respect to the box main body 2 in the vertical direction and adjusting the vertical height of the device storage part 7, the positions of the power transmission coils 20, 20... in the device storage parts 7, 7... can be relatively adjusted. Further, the detection plate 5 that closes the rear side of the device storage part 7 is erected on the mounting plate 4, and by changing the installation position of the detection plate 5 on the mounting plate 4 in the front - rear direction and adjusting the front - rear depth of the device storage parts 7, 7..., the positions of the power transmission coils 20, 20... in the device storage parts 7, 7... can be relatively adjusted. Therefore, since the size of the device storage parts 7, 7... can be adjusted to cope with differences such as the size of the tablet terminal 50 and the position of the power receiving coil in the tablet terminal 50, cost reduction can be achieved and the charging device 1 can be made excellent in usability. Also, by changing the installation position of the mounting plate 4 in the vertical direction, the vertical height of all the device storage parts 7, 7... can be adjusted simultaneously, and by changing the installation position of the detection plate 5 in the front - rear direction, the front - rear depth of all the device storage parts 7, 7... can be adjusted simultaneously, so that the adjustment work can be simplified.

Also, for example, in the charging device of the first embodiment, similar to the second embodiment, the coil unit can be provided such that its mounting position can be changed. Furthermore, in the charging device of the first embodiment, it is also possible to configure it such that only the vertical height of the device storage portion by the mounting plate can be adjusted, or it may be configured such that only the front-rear depth of the device storage portion by the closing plate can be adjusted. In addition, in the charging device of the first embodiment, although it is stated that elongated adjustment holes or adjustment slits are provided for the adjustment of the vertical height and the front-rear depth, for example, a plurality of installation holes can be arranged in the vertical direction on the side plate of the box body, or a plurality of installation holes can be arranged in the front-rear direction on the adjustment piece, and by changing which installation hole is used to install the mounting plate or the closing plate, it is also possible to adjust the vertical height and the front-rear depth. The specific structure related to the change of the installation position can be appropriately designed and changed. Needless to say, the mounting structure of the coil unit is not limited to the structure of the second embodiment above.
