  However, in the conventional connection structure, in order to enable opening and closing of the first object and the second object, a virtual rotation axis (hereinafter referred to as rotation) generated corresponding to one rotation axis or a plurality of sets of rotation axes. There is only one centerline). For this reason, the first object and the second object open and close only in one direction. That is, the opening / closing mode of an apparatus having a conventional connection structure is limited. As a result, the apparatus has a low degree of freedom in arrangement of the first object and the second object when the first object and the second object are opened, and cannot flexibly cope with various usage forms.

  In addition, in order to increase the degree of freedom of arrangement of the first object and the second object, the first object and the second object are made detachable, and the first object and the second object are arranged separately according to the usage form. However, when the first object and the second object are separated, it is necessary to manage the first object and the second object separately, so the first object and the second object are integrated. The user's convenience is lower than that of the user.

  The present invention has been made in view of such circumstances, and includes the first object and the second object by connecting the first object and the second object, and further including two pivotal support portions that can be released from the connection. However, it is an object of the present invention to provide a connection structure that can be folded and opened in two different directions, and an imaging apparatus and a reproduction apparatus including the connection structure.

The connection structure according to the present invention includes a first pivot part that couples a part of the first object and the second object, and the first object and the second object are rotatable around the first pivot part. In the connection structure, the first pivot support part is configured to be able to release the connection between the first object and the second object, and the other parts of the first object and the second object are connected to each other. A second pivot part connecting the first object and the second object, wherein the first object and the second object are rotatable around the second pivot part. Ri Thea and configured to be capable to be uncoupled and the object, the first pivot portion and / or the second pivot portion includes a rotating shaft, the rotating shaft support portion for supporting the rotary shaft, the rotary Opening support in which an opening is formed so that the shaft is fitted and supported, and the rotating shaft can be fitted and removed in the radial direction of the rotating shaft. And a lock part that closes / opens the opening, and the lock part has a plate shape or a bar shape, and the opening support part and the lock part include the first and second lock parts. Provided in one of the one object and the second object, the one is operated in a direction intersecting the opening / closing direction by the lock portion and an elastic portion that holds the lock portion in a state in which the opening is closed An operating portion for applying an external force to the locking portion in a direction to open the opening, and an L-shape, and the operating portion is connected to one end of the L-shape, A connecting portion connected to the other end of the L-shape and the elastic portion, the connecting portion being rotatable, and rotating in one direction when the operating portion is operated. The external force is applied to the lock part by and the opening part is closed. Characterized Citea Rukoto to rotate in the other direction in the case of adding an elastic restoring force of the elastic portion to hold the locking portion to condition the locking portion.

  In the present invention, each of the first pivot part and the second pivot part has at least one rotation center line generated by the structure of each pivot part (for example, a concave part and a convex part loosely fitted thereto). That is, the connection structure of the present invention has one or more rotation center lines in part and other parts of the first object and the second object. In addition, since each pivotal support portion can release the connection between the first object and the second object, the other pivotal support portion is released by releasing the connection between the first object and the second object at one pivotal support portion. Thus, the first object and the second object can be rotated around the rotation center line. Furthermore, when both the first pivot part and the second pivot part connect the first object and the second object, the first object and the second object are restrained at two points. Is possible. As a result, the first object (for example, the numeric keypad side of the mobile phone) and the second object (the display unit side of the mobile phone) are foldable or 180 ° when the connection is released at one pivotal support portion.

In addition, since the first pivot part and the second pivot part are provided in a part and other parts of the first object and the second object, respectively, when opening and closing around the first pivot part and around the second pivot part The opening and closing directions of the first object and the second object are different depending on the case of opening and closing.

  In addition, although a hinge-shaped or pivot-shaped pivot part has a rotation center line, when the pivot part is constituted by one ball joint, such a pivot part has a rotation center point. However, when rotating in one direction about the ball joint, the first object and the second object can be regarded as rotating around the rotation center line. Unless otherwise noted, pivots are treated as having a centerline of rotation.

Furthermore , since the rotary shaft support part loosely fits, or is fixedly fitted to the rotary shaft, or has the integral, and the opening support part loosely fits or fits the rotary shaft, the rotary shaft and the rotary shaft support part Alternatively, one or both of the opening support portions rotate. With such a configuration, a rotation center line is generated in the pivot portion. In this case, when the pivotal support portion includes a plurality of rotation shafts, it is desirable that rotation center lines corresponding to the respective rotation shafts are continuous. In addition, since the rotation shaft of the opening support portion is detachable in the radial direction, when the rotation shaft is inserted into the opening support portion, the connection between the first object and the second object is maintained at the pivot portion, When the rotating shaft is detached from the opening support part, the connection between the first object and the second object is released at the pivotal support part.

Furthermore , when the locking part is separate from the rotating shaft and the opening formed in the opening support part is closed, the locking part prevents the rotating shaft from being detached from the opening support part, When the opening is locked by the lock, the rotation shaft can be detached from the opening support. For this purpose, it is desirable that the opening support portion and the lock portion are provided on one of the first object and the second object. Further, when the opening is closed by protruding the locking portion into the opening, the opening supporting portion is provided in one of the first object and the second object, and when the locking portion is provided in the other, the opening is provided. When the lock portion protrudes, the lock portion inhibits the rotation of the opening support portion, and when the lock portion is retracted from the opening portion, the opening support portion can rotate.

Further , the elastic portion holds the lock portion and closes the opening formed in the opening support portion. Further, for example, when the user operates the operation unit in a direction crossing the opening / closing direction by the lock unit , an external force in a direction to open the opening is generated by rotating the connecting unit to which the elastic unit is connected in one direction. added to Gallo click section, Therefore, to open the opening lock unit is moved. Further, for example, when the user stops the operation of the operation unit, the lock unit moves when the connecting unit rotates in the other direction due to the elasticity of the elastic unit, and is held again in a state of closing the opening.

  Further, in the connection structure according to the present invention, the first object and the second object have a flat rectangular parallelepiped shape, and the first pivot part is provided on one end surface side of each of the first object and the second object. The second pivotal support portion is provided on the other end surface side continuous with the one end surface side.
