<P>PROBLEM TO BE SOLVED: To provide an electronic device that can stably mount a circuit board without using a screw. <P>SOLUTION: The electronic device 1 comprises: a circuit board 4 having an electronic circuit mounted; a case 2 having an opening 5 at the lower side and housing a circuit board 4 therein; and a box-shaped cover 3 having an opening at the upper side and closing the opening 5 at the lower side of the case 2. The case 2, in which grooves 8 that can insert edges of the circuit board 4 are formed in a horizontal direction in a pair of opposing internal surfaces, is intended for housing the circuit board 4 by sliding both edges of the circuit board 4 from a lateral opening 6 formed on a lateral of one side of the groove 8 into the groove 8. The cover 3 has protruding portions 14 protruding from the top edges of the pair of opposing sidewalls 31 arranged in parallel with the grooves 8, where the protruding portions 14 are designed to get into gaps between the edges of the circuit board 4 and the grooves 8 to fix the circuit board 4. <P>COPYRIGHT: (C)2013,JPO&INPIT |
