A rack configured to be mounted with a front panel in an openable/closable manner includes: a protrusion part provided in a flat plate shape on a frame near a front surface of the rack; and a screw hole formed in the protrusion part, wherein a screw is mounted to the screw hole in a state where a slit formed along one end portion of the front panel is inserted into the protrusion part.

Abstract: An electronic device and a battery pack housing structure capable of housing a battery pack without use of a contour width of the battery pack for positioning. The battery pack housing structure includes a battery-pack lower-surface protruding portion protruding from a lower surface of the battery pack and the housing portion including a housing-portion bottom-surface groove portion, which is formed in a bottom surface of the housing portion and capable of being fitted to the battery-pack lower-surface protruding portion.

Abstract: Provided are an electronic device and a battery pack housing structure capable of housing a battery pack without use of a contour width of the battery pack for positioning.

Abstract: Provided is a charging stand which, with a simple structure, prevents a force applied to a power cord from being transmitted directly to a connecting portion between the charging stand and the power cord. A charging stand 100 comprises a housing 110 having a seat portion 114 for placing an electronic apparatus 300 thereon and a charging mechanism for charging the electronic apparatus 300 when the electronic apparatus 300 is placed on the seat portion 114. A cord winding structure 140 for winding thereon a power cord 220 adapted to be connected to the charging stand 100 is provided at a bottom surface of the housing 100.
