Title: CALCULATOR
Abstract:
This calculator has: a housing having one or more through holes, through which modules are inserted/removed; and a rear surface plate, which is a plate-like member fixed to the housing such that through hole openings on the side opposite to through hole openings through which the modules are inserted/removed are closed, said rear surface plate having a plurality of plate surface connectors that are provided on a plate surface such that the plate surface connectors are positioned in the opposite-side openings. The modules have: a first substrate having first connectors that couple to first plate surface connectors of the plate surface connectors in the cases where the modules are inserted into the through holes; a second substrate having second connectors that couple to second plate surface connectors of the plate surface connectors in the cases where the modules are inserted into the through holes; and a module housing, which disposes the first substrate and the second substrate such that the first connectors and the second connectors face the rear surface plate, and the first substrate is positioned above or below the second substrate, and which holds the first substrate such that the first substrate can freely slide in the inserting/removing direction with respect to the through holes of the modules, said module housing fixing the second substrate.
