PROBLEM TO BE SOLVED: To prevent a printed board, inserted into/removed from an apparatus, from coming off even if a force is applied to the printed board in the inserting/ removing direction. SOLUTION: A printed board 3 can be inserted/removed from the slot part 2a of a housing. The state where the printed board 3 is contained in the slot part 2a is held fixedly by an engaging means 13. The engaging means 13 comprises an engaging protrusion 22 formed on the printed board 3 side, and an engaging plate 21 provided on the slot part 2a side along the insertion/ drawing direction of the printed board 3. When the printed board 3 is contained, an inclining piece 22c pushes up the engaging plate 21 which thereby engages with an engaging hole 22c. Under that state, the vertical side 22a engages with an engaging hole 22c and the printed board 3 is prevented from coming off even if the printed board 3 is given a force for drawing it out forward. The engaging plate 21 is bent by an operation for bending an operating piece 21b upward, the engaging hole 22c is released from the engaging protrusion 22 and the printed board 3 can be taken out forward.
