As described above, in the power supply system 100 according to the present embodiment, the first fixing portion 142 that fixes the external device 200 to the casing 140 is fixed to the casing 140 and at least one of the side surfaces of the casing 140 is fixed. It is enclosed in the housing 140 by an openable and closable lid portion 143 constituting the portion. In other words, since the first fixing portion 142 to which the external device 200 is fixed is enclosed in the housing 140 by the lid portion 143 that can be freely opened and closed, the first fixing portion 142 is the housing in a state where the lid portion 143 is closed. Visible from the outside of 140 can be suppressed. For this reason, it can suppress that fixation of the external device 200 can be suppressed, and it can suppress that the external device 200 is stolen.

  Moreover, the area | region which exists in the perpendicular direction of the 1st fixing | fixed part 142 exists in the range which the cover part 143 occupies for the perpendicular direction. That is, when the external device 200 is fixed to the first fixing portion 142 or the external device 200 is removed from the first fixing portion 142 with the lid portion 143 opened, the first fixing portion 142 is moved in the vertical direction.
