  The recording apparatus disclosed in Patent Document 1 has a configuration in which the support member is supported on the upper surface of a housing (housing member) that forms the appearance of the apparatus (in Patent Document 1, “restraining portion 119” is “lower”. Formed on the casing 111 ").

  That is, since the scanner unit is supported by the “upper surface of the housing” that is weak in strength, the wall (hereinafter referred to as “upper wall”) that configures the upper surface of the housing is deformed by the weight of the scanner unit, Further, when the user places his / her hand on the scanner unit, the housing may be further deformed.

  When the upper wall of the housing is deformed, the posture of the scanner is not stable. In addition, there is a possibility that the upper wall of the casing interferes with the carriage travel area located below the casing, and the carriage comes into contact with the upper wall of the casing. In order to prevent such a problem, it may be possible to secure a large clearance between the carriage travel region and the upper wall of the housing, but in this case, it is against the demand for downsizing of the apparatus.

  In addition, it is conceivable to separately provide a deformation preventing means (for example, a support column) for preventing the deformation of the upper wall of the housing. However, the cost increases due to an increase in the assembly process, or the upper wall of the housing is connected to the scanner unit. Although it is possible to divide the portion into a portion that supports the carriage and a portion that covers the carriage travel region, in that case, the aesthetic appearance of the apparatus is impaired. Further, if a reinforcing structure such as a rib is provided to increase the rigidity of the casing itself, molding defects such as sink marks are likely to occur, which is not preferable in terms of appearance.

  Accordingly, the present invention has been made in view of such a situation, and an object thereof is to provide a configuration in which an open posture of a rotatable rotating body provided at an upper portion of the apparatus main body is maintained by an arm (support member). In the recording apparatus, it is intended to appropriately prevent deformation of the casing constituting the appearance of the apparatus.

A pivotable body that can be opened and closed by this, and an arm that is rotatably supported at one end side by the pivotable body and the other end side is supported by a support portion of the apparatus body, thereby maintaining an open posture of the pivotable body. The apparatus main body includes a base frame that forms a base of the apparatus main body, and a housing member that covers the base frame and forms an appearance of the apparatus main body, and the support portion is provided on the base frame. And a structure in which the support portion is exposed from an opening formed in the housing member.

  According to this aspect, the support portion that supports the arm that maintains the open posture of the rotating body is provided on the base frame that forms the base of the apparatus main body, not the housing member that forms the external appearance of the apparatus main body. In addition, since the support portion is exposed from the opening formed in the housing member, and the arm is directly supported by the base frame, deformation of the housing member constituting the appearance of the apparatus can be appropriately prevented.

According to a second aspect of the present invention, in the first aspect, the support portion is supported by a wall that is erected along a vertical direction and that constitutes the base frame.
According to this aspect, since the support portion is supported by the wall that stands up along the vertical direction that constitutes the base frame, the rotating body is more reliably supported (via the arm). be able to.

  According to a third aspect of the present invention, in the second aspect, the base frame includes a first wall that constitutes the wall and a second wall that constitutes the wall at a predetermined interval. The support portion is provided at a connection portion that is spanned between the first wall and the second wall.

  According to this aspect, since the support portion is provided in the connection portion that is spanned between the first wall and the second wall that are erected along the vertical direction, By receiving the load received by the first wall and the second wall, the rotating body can be more reliably supported (via the arm).

  According to a fourth aspect of the present invention, in the third aspect, the third wall that is erected along the vertical direction and that forms a plane that intersects the first wall and the second wall, It is connected with 1 wall and the said 2nd wall, It is characterized by the above-mentioned.

  According to this aspect, the third wall that is erected along the vertical direction and that forms a plane that intersects with the first wall and the second wall is the first wall and the second wall. Therefore, the rigidity of the first wall and the second wall is improved by the third wall, whereby the rotating body can be supported more reliably.
