Description

BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to an electronic apparatus including a substrate and an electronic module fixed to the substrate, and a fixing structure for fixing the electronic module to the substrate. Description of the Related Art In an electronic apparatus such as a laptop PC, a detachable electronic module may be provided on a substrate. An electronic module in an electronic apparatus disclosed in Japanese Patent No. 7531669 has one end connected to a connector mounted on a substrate, and the other end fixed to the substrate with a screw. Such an electronic module is replaceable by removing the screw. SUMMARY OF THE INVENTION Incidentally, since the screw used for such fixation is small, it is difficult to handle the screw in a narrow area inside a chassis. The present invention has been made in view of the above-described problem, and an object of the present invention is to provide an electronic apparatus and a fixing structure that facilitate easy handling of a screw for fixing an electronic module to a substrate. In order to solve the above-mentioned problem and achieve the object, an electronic apparatus according to a first aspect of the present invention includes: a substrate; and an electronic module fixed to the substrate, in which the electronic apparatus has a bracket that is provided along an edge portion forming one end of the electronic module, a screw that is rotatably provided on the bracket and configured to fix the edge portion of the electronic module to the substrate, and a sheet that protrudes from the bracket to a side opposite to the electronic module. A fixing structure according to a second aspect of the present invention fixes an electronic module to a substrate, the fixing structure including: a bracket that is provided along an edge portion forming one end of the electronic module; a screw that is rotatably provided on the bracket and configured to fix the edge portion of the electronic module to the substrate; and a sheet that protrudes from the bracket to a side opposite to the electronic module. The above-described aspects of the present invention facilitate easy handling of the screw for fixing the electronic module to the substrate.
