Claim of US Patent No. 10,893,625

1. An electronic machine comprising:a casing body having an electronic circuit board insertion port on one surface;
a plurality of electronic circuit boards each including: a circuit board, on which electronic components are mounted; and a front panel connected to the circuit board and having a first conductive side portion located in a longitudinal direction side portion and a second conductive side portion located opposite to the first conductive side portion, the plurality of electronic circuit boards being inserted in parallel through the electronic circuit board insertion port of the casing body with gaps between the front panels adjacent to each other; and
a conduction device having a first bridge body, and in electronic circuit boards adjacent to each other in the plurality of electronic circuit boards, the first bridge body electrically conducting the first conductive side portion of the front panel in one electronic circuit board of the electronic circuit boards adjacent to each other and the second conductive side portion of the front panel in another electronic circuit board that faces the first conductive side portion via a gap,
wherein each of the plurality of electronic circuit boards has a plurality of engagement portions on the first conductive side portion and the second conductive side portion along the longitudinal direction, the conduction means has a plurality of first bridge bodies, and each of the first bridge bodies is a conductive plate having: one end screwed to a selected engagement portion of a plurality of engagement portions provided on the first conductive side portion of the front panel in one electronic circuit board of electronic circuit boards adjacent to each other and another end screwed to a selected engagement portion of a plurality of engagement portions provided on the second conductive side portion of the front panel in another electronic circuit board.
