There is provided an electric device module including: a housing; a board member fixed to one inner side of the housing and including a plurality of connecting terminals; at least one board adhered to another inner side of the housing by a predetermined adhesive and including a plurality of terminals electrically connected to the plurality of connecting terminals; and a guider guiding a mounting position of the board. In the electric device module, a circuit board is prevented from changing in adhering position due to fluidity of an adhesive but can be adhered at a precise position. Also, an extra amount of the adhesive is prevented from flowing outside the circuit board to thereby enhance accuracy and reliability in terms of terminal connection.

A connection device for connecting between a multifunction peripheral and USB devices. A hub unit is disconnectably connected to the multifunction peripheral via a first interface for enabling power supply from the multifunction peripheral to the hub unit. The hub unit is also disconnectably connected to the USB devices via a second interface for enabling power supply from the hub unit to the USB devices. A dedicated power supply connector is connected to a power supply section of the multifunction peripheral via wiring for enabling power supply from the multifunction peripheral to the hub unit. A hub circuit relays data between the multifunction peripheral and one of the USB host connectors of the hub unit. Power from the first interface to the hub circuit is supplied through a first power path, and power from the multifunction peripheral to the USB devices is supplied through a second power path.
