Claim Text:
1. An electronic device comprising: a shelf where a first slot and a second slot are formed to be abutted with each other in a first direction; a plurality of kinds of electronic circuit boards inserted into any one of the first slot and the second slot, and when a vertical direction against both of the first direction and a direction in which the electronic circuit boards are inserted into the first slot is defined as a second direction, including a first-side protrusion portion installed at a first-side of the second direction and a second-side protrusion portion installed at a second-side that is different from the first-side of the second direction, and an arrangement pattern of the first-side protrusion portion and the second-side protrusion is different from each other; a first abutment member installed against the first slot and rotatable around an axis of the first direction, and when an electronic circuit board of a kind having the first-side protrusion portion at the first position of the first direction is inserted into the first slot with the second slot is in an empty state, configured to abut the first-side protrusion portion of the first position and rotate from a first angle position to a second angle position; a second abutment member installed against the first slot and rotatable around an axis of the first direction, and when an electronic circuit board of a kind having the first-side protrusion portion at a second position different from the first position of the first direction is inserted into the first slot with the second slot is in an empty state, configured to abut the first-side protrusion portion of the second position and rotate from the first angle position to the second angle position; a first interlocking member installed against the second slot and rotating around an axis of the first direction either from a limit position to a retreat position or from the retreat position to the limit position, when in the retreat position and when an arbitrary electronic circuit board among the plurality of circuit boards is inserted into the second slot, configured not to interfere with the second-side protrusion portion of the arbitrary electronic circuit board, and when in the limit position and when an electronic circuit board of a kind having the second-side protrusion portion at a third position of the first direction is inserted into the second slot, configured to interfere with the second-side protrusion portion of the third position and block an insertion of the electronic circuit board of a kind having the second-side protrusion portion of the third position into the second slot; and a second interlocking member installed against the second slot and rotating around the axis of the first direction from the limit position to the retreat position or from the retreat position to the limit position by interlocking with a rotation of the second abutment member from the first angle direction to the second angle direction, when in the retreat position and when an arbitrary electronic circuit board among the plurality kinds of circuit boards is inserted into the second slot, configured not to interfere with the second-side protrusion portion of the arbitrary electronic circuit board, and when in the limit position and when an electronic circuit board of a kind having the second-side protrusion portion at a fourth position different from the third portion of the first direction is inserted into the second slot, configured to interfere with the second-side protrusion portion of the fourth position and block an insertion of the electronic circuit board of a kind having the second-side protrusion portion at the fourth position into the second slot.
