Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a sectional view of an embodiment of the present invention, FIG. 2 is a bottom view, and FIG.
The figure is an exploded perspective view. The charger case of the present embodiment includes a front case 21 that houses the electric circuit portion, a rear case 23 for stably installing the front case 21, and a cover 25 that serves as a mounting base for the device to be charged. . The cover 25 is sandwiched between the front case 21 and the rear case 23 and is integrally fixed by a tapping screw 27. Front case
21 includes a tapping screw portion 29 to which the tapping screw 27 is fastened.
And a printed board supporting portion 31 that supports the printed board 35 are integrally formed. Further, on the front surface of the front case 21, there is formed a leaning surface 30 which is leaned at a predetermined angle for leaning a device to be charged. The rear case 23 is integrally formed with a protruding portion 33 having a tapping screw insertion hole 33a formed therein and a pair of printed board supporting portions 37 for supporting the printed board 35. A plurality of rubber feet 39, for example, four rubber feet 39, are attached to the bottom surface of the rear case 23.

As best shown in FIG. 3, two pins 43 are attached to a charging target device mounting surface 41 of the cover 25 so as to be vertically movable by an E ring 47 via a coil spring 45. Further, the mounting surface 41 is provided with a protrusion 49 for pressing the lower end of the front surface of the device to be charged. A terminal 51 for charging the spare battery pack is attached to the back surface of the cover 25.
Reference numeral 55 denotes an LED board to which two LEDs 53 are attached, which is attached to the inside of the cover 25 by a nylon rivet 57. The LED 53 is for monitoring the state of charge of the device to be charged and the spare battery pack, and the completion of charging can be known from the color of light emitted from the LED 53.
