Ruler device module

A computing system comprising:

• a chassis including:
• two side plates;
• a front window and a rear window at opposite ends of the two side plates;
• two pins, with each pin extending from a separate one of the two side plates and at the front window;
• and
• a fastener;
• a main board housed within the chassis;
• a ruler device module including:
• a top plate;
• a bottom plate parallel to the top plate and extending beyond the top plate in one direction, the bottom plate defining a tray where the bottom plate extends beyond the top plate;
• a pair of side plates on opposite sides of, and extending between, the top plate and the bottom plate, each side plate including a slot that is configured to engage with one of the two pins;
• partitions perpendicular to and between the top plate and the bottom plate forming bays between adjacent partitions and between the top plate and the bottom plate, each bay being configured to retain a ruler device;
• and
• a handle structure recessed within the top plate, the handle structure including a handle configured to rotate between a recessed position, in which the handle is recessed within the top plate, and a use position, in which the handle extends perpendicular to the top plate, for removing and inserting the ruler device module from the chassis;
• and
• a daughter board coupled to the ruler device on the tray, the daughter board configured to connect the ruler device module to the main board,
• wherein the tray includes a plurality of posts upon which the daughter board sits for coupling the daughter board to the tray.
