It is necessary to. In addition, in the electronic device described in Patent Document 2 or the like, when the projecting main body is inclined from the vertical storage posture to the horizontal posture or a state close to the horizontal posture and attempts to largely protrude forward, the moving support body is moved in the front-rear direction. It is necessary to secure a long moving distance.

  Further, in the protruding posture in which the protruding main body protrudes forward of the housing, the protruding main body is supported by the moving support body. At this time, if the support span in the front-rear direction within the casing of the movable support is short, the projecting main body cannot be stably supported by the movable support, and vibration is generated from the outside like an in-vehicle electronic device. In an electronic device that is easily applied, there arises a problem that the moving support body and the protruding main body are rattled due to vibration, and an irritating rattling sound is likely to occur.

  Therefore, when the projecting body is in the projecting posture, if the support span in the front-rear direction of the movable support is lengthened in the housing to stably support the projecting body, the dimension of the movable support itself in the front-rear direction is increased. I have to do it.

  However, as described above, if the moving distance of the moving support is increased and the front and rear dimensions of the moving support are increased, it is possible to secure a long space for the moving support to move back and forth in the housing. Necessary. Therefore, the depth of the housing must be increased, and conversely, if the depth of the housing is to be reduced, the protruding body should be made smaller and the protruding amount of the protruding body to the front of the housing should be shortened. Is required.

  The present invention solves the above-described conventional problems, and has a projecting body that can stably support a projecting body in a projecting posture even when there is a restriction on a moving space before and after the movable support in the housing.

It is possible to increase the moving distance.

For example, the extension support is rotatably supported by the movable support with a pivot centerline extending vertically as a fulcrum,
When the projecting body is in the stowed position, the extension support is rotated and stored between the rear end of the housing and the moving support body. When the projecting body is in the projecting position, the extension support body is the moving support body. It will be the posture which extends backward from.

  In this case, it is preferable that posture stabilization means is provided for stabilizing the extended support in a posture extending rearward of the movable support when the protruding main body is in the protruding posture.

  The posture stabilizing means is a biasing member that biases the extension support body to a posture extending rearward of the movable support body. Alternatively, the posture stabilization means is a restricting member that engages with the extension support as the moving support moves forward, and stabilizes the extension support in a posture that extends rearward of the movement support.

  Further, at least one of the rear end of the extended support and the rear end of the housing is arranged such that the extended support is accommodated between the rear end and the movable support when the movable support is retracted. What is provided with the inclined surface or curved surface which guides so that it may rotate is preferable.

It can be surely stored between the body and the rear end face of the housing.

  In the present invention, the extension support may be supported by the movable support so as to protrude rearward and contract.

  Also in this case, it is preferable that posture stabilization means is provided for stabilizing the extended support in a posture extending rearward of the movable support when the protruding main body is in the protruding posture.

  For example, the posture stabilization means is a biasing member that causes the extension support to protrude rearward of the moving support. Alternatively, the posture stabilization means is a restricting member that engages with the extension support as the movement support moves forward, and projects the extension support toward the rear of the movement support.

  The present invention is applicable to a projecting main body on which at least one of a display device and an operation member is mounted.

  In the present invention, when the projecting body is in the projecting posture, the front and rear support spans of the movable support body can be substantially lengthened, and the projecting body in the projecting posture can be stably supported. Shaking of the main body can be suppressed. Further, when the projecting main body is housed, the movable support can be retracted to a position approaching the rear end of the housing. Therefore, it is possible to increase the distance of movement of the movable support body without increasing the depth dimension of the housing, and to make the projecting main body largely project forward of the housing.
