A substrate mounting structure includes a first substrate having a first connector on a front surface thereof, a second substrate having a second connector attached to and detached from the first connector, and a board covering a part of the first substrate Shaped member. The plate-like member is formed by bending a part of the plate-like member toward the first substrate, and the second connector with respect to the first substrate when the second connector is attached to the first connector A second attitude restricting portion that is formed by bending a part of the plate-like member and that is formed by bending a part of the plate-shaped member, and in a state in which the second connector is attached to the first connector, And a position restricting portion for restricting a position where the first position is disposed.基板の取り付け構造は、表面に第1コネクタが設けられた第1基板と、前記第1コネクタに着脱される第2コネクタが設けられた第2基板と、前記第1基板の一部を覆う板状部材とを備える。前記板状部材は、前記板状部材の一部を前記第1基板側に折り曲げることで形成され、前記第2コネクタが前記第1コネクタに装着される際の前記第1基板に対する前記第2基板の姿勢を規制する姿勢規制部と、前記板状部材の一部を折り曲げることで形成され、前記第2コネクタが前記第1コネクタに装着された状態において前記第1基板に対して前記第2基板が配置される位置を規制する位置規制部と、を有する。
