JP-A-10-133780 (paragraph [0015], FIGS. 1-2)

  In the technique described in Patent Document 1, since a plurality of movable support members are used, the number of parts is increased and the cost for the increased parts is increased. In addition, when connecting connectors, loads are generally applied in the vertical and horizontal directions. However, according to the structure in which the substrate is sandwiched between the bearings, the load from the horizontal direction is resistant, but the resistance to the load from the vertical direction is not considered. For this reason, there is a possibility that the connector and the board may be damaged by receiving an impact from the vertical direction. Furthermore, with the technique described in Patent Document 1, the connector and the board once moved in the horizontal direction do not naturally return to their normal positions. For this reason, when the connection operation with the connector of the PC is performed next, the workability may be significantly reduced.

  In view of the circumstances as described above, an object of the present invention is to provide an electronic device capable of suppressing an increase in the number of parts and an increase in cost and improving connectivity with an external device.

  In order to achieve the above object, an electronic apparatus according to the present invention includes a main body portion, a metal frame member, a connector portion, and a metallic elastic support member. The main body has a placement surface on which an external device can be placed. The frame member is provided on the main body. The connector portion is provided so as to protrude from the mounting surface and can be connected to the external device. The elastic support member elastically supports the connector portion in the biaxial direction on the frame member.

  According to the present invention, since the elastic support member supports the connector portion in the biaxial direction, the connector portion is movable in the horizontal direction, for example. Further, since the elastic support member elastically supports the connector portion, the moved connector portion can be returned to the normal position. With this structure, the connector portion can obtain desired connectivity with respect to the external device.

  In the present invention, the elastic support member further elastically supports the connector portion on the frame member in an axial direction orthogonal to the biaxial direction.

  According to the present invention, the connector portion is further movable, for example, in the vertical direction. Thereby, when the external device is mounted on the electronic device, the impact from above which the connector portion may receive is alleviated by the elastic force of the elastic support member. For this reason, the possibility of breakage of the connector portion is reduced.

  In the present invention, the electronic device further includes a lid portion that is rotatably provided with respect to the main body portion so as to open and close the mounting surface including the protruding portion of the connector portion.

  In this invention, the said cover part has an accommodating part which can accommodate the protrusion part of the said connector when the said mounting surface is closed.

  According to the present invention, the connector part protruding from the placement surface can be protected by the lid part. As a result, foreign matter such as dust adheres to the connector portion, and the possibility that the connectivity of the connector portion is impaired is reduced. Moreover, the cover part is provided in the main-body part so that rotation is possible. In other words, since the lid is not a separate part such as a cover, there is no possibility that the lid is lost. Furthermore, design property improves by covering a connector part with a cover part.

  In the present invention, the electronic device further includes a hinge mechanism that rotatably supports the lid portion with respect to the main body portion, and a restriction portion that restricts rotation of the hinge mechanism. The hinge mechanism includes a first shaft provided in the lid portion, a second shaft provided in the main body portion, and one end portion rotatably supported by the second shaft, and the other end portion. And a holding member having a shaft holding portion having a shaft hole for rotatably holding the first shaft. A first engaging portion and a second engaging portion are provided on a peripheral surface of the peripheral surface of the second shaft and a peripheral surface of the shaft holding portion of the holding member that faces the peripheral surface of the first shaft. It is done. The first engaging portion restrains the state in which the lid portion is opened to the first fixed position at which the placement surface is exposed with respect to the main body portion. The second engaging portion constrains the state where the lid portion is closed to the second fixed position where the mounting surface is closed with respect to the main body portion. When the main body portion reaches a predetermined third fixed position on the way from the first fixed position to the second fixed position with respect to the lid portion, The rotation about the second axis is restricted.

  In the present invention, the hinge mechanism includes a first recess and a second recess that are spaced apart from each other on the circumferential surface of the first shaft and are provided along the axial direction of the first shaft; And a convex portion that is provided on a peripheral surface of the shaft hole of the shaft holding portion of the holding member and can be fitted into the first concave portion or the second concave portion. The first engagement portion is formed by engagement of the first concave portion and the convex portion. The second engaging portion is formed by engaging the second concave portion and the convex portion.

  According to the present invention, when the first engaging portion and the second engaging portion are provided, the lid portion rotates when the lid portion is located at the first fixed position and the second fixed position. It is possible to prevent fine movement and rattling in a possible direction.

  As described above, according to the electronic device of the present invention, it is possible to suppress an increase in the number of parts and an increase in cost, and to improve connectivity with external devices.
