PROBLEM TO BE SOLVED: To share the board block of the same function appropriately in space and cost by, related to a holding part where the positional relationship between an electronic element and base stage is variable, forming the electronic element on a recessed track which engages with a protruding end part of the electronic element, with an auxiliary track connected in the direction perpendicular to a sliding direction. SOLUTION: A holding part is provided to a base stage 8 where, with an electronic element 1 detachable, the positional relationship between the electronic element 1 and the base stage 8 is variable. An end part 6 of the electronic element 1 is engaged at the holding part, while a track 4 for sliding of the electronic element 1 is provided. Related to the holding part, the electronic element 1 is formed at the recessed track 4 which comprises guides 2 so provided as to face each other and engages with the protruding end part 6 of the electronic element 1, with an auxiliary track 5 connected in the direction perpendicular to the sliding direction. With the auxiliary track 5 engaged with the end part 6, the electronic element 1 is held in gravity direction.
