The door plate 2 is frictionally engaged with the inner wall of the side wall that approaches the side walls 11 and 14 of the recess 1 in this open position, and the door plate 2 is held in the open position by this frictional engagement. Unless the force to overcome the friction is applied in the direction of the arrow in FIG. 12B, the door plate 2 does not pivot to the state in FIG. Accordingly, by applying a force to the door plate 2 to overcome the friction from the state shown in FIG. 12B, which is the open position, the bracket 20 is pivoted about the support column 40 to the closed position.

However, conventional electronic devices having a door opening / closing mechanism have the following drawbacks.
(A) The door plate 2 and the side walls 11 and 14 are scratched by frictional engagement between the door plate 2 and the opposing side walls 11 and 14 of the recessed portion 1 with the passage of time.
(B) The material is scraped by friction between the door plate 2 and the opposing side walls 11 and 14 of the recess 1 due to use over time, the engagement becomes loose, and the open state cannot be maintained.
(C) Since the door plate 2 cannot be kept open by friction unless the inner diameter of the bracket receiving members 21 and 21 is made smaller than the outer diameter of the support column 40 provided in the recess 1, the inner diameter when the door plate 2 is attached. It becomes difficult to attach the bracket receiving members 21 and 21 having a small height, and workability is significantly reduced.
(D) By reducing the inner diameters of the bracket receiving members 21 and 21, there is a risk that problems such as breaking of the bracket receiving members 21 and 21 occur when the door plate 2 is attached.
(E) By reducing the inner diameters of the bracket receiving members 21, 21, a load is applied to the bracket 20 during the opening / closing operation of the door plate 2, and the door plate 2 cannot be opened / closed smoothly, resulting in a deterioration in quality.
(F) In order to eliminate the problems “(c)” and “(d)”, the opening of the bracket receiving members 21 and 21 that receive the cylindrical surface 41 of the support column 40 (the non-contact portion with the support column 40) is increased. In this case, there is a possibility that the contact area between the cylindrical surface 41 and the bracket receiving surfaces 22 and 22 is reduced, and sufficient frictional holding cannot be performed.
(G) When selecting the inner diameter dimension of the bracket receiving members 21 and 21 and the outer dimension dimension of the support column 40 so as not to cause the problems “(c)” to “(f)”, check the actual fitting state. In addition to the need for repeated corrections and strict dimensions, the cost of correcting expensive molds and extra correction time are required.
