JP 2003-125052

  The device described in Patent Document 1 attaches a slide case in which a slide cover and a lock plate are overlapped and fixed to a lower surface of a second housing, and also includes a slider that is slidably accommodated in the slide case. By attaching to the upper surface of the housing, the second housing can be slid with respect to the first housing. With such a configuration, all the relative operations of the first housing and the second housing, that is, the slide operation must be performed manually, which is difficult in terms of operability.

  For this reason, it has been proposed to provide a compression spring between the slider and the slide case as a biasing means for biasing the slider in the opening direction. As a result, when the second casing is slid with respect to the first casing to change from the closed state to the open state, the opening operation can be automatically performed. However, the first casing is supported by the compression spring. When the body and the second casing are slid relative to each other, the slide stroke in which the compression spring is movable becomes longer in the longitudinal direction of the first casing and the second casing, and a large space is required.

  In addition, when the first housing and the second housing are slid relative to each other, the upper surface of the first housing and the lower surface of the second housing are substantially flush with each other when the first housing and the second housing are slid linearly in a side view. May be located. In this case, for example, a microphone is provided near the rear end of the upper surface of the first housing, and a speaker is provided near the front end of the lower surface of the second housing. The microphone part of the first casing cannot be brought close to the mouth, and the speaker part of the second casing cannot be brought close to the ear. In addition, it is difficult to operate the keyboard portion of the first housing while viewing the image displayed on the display unit on the upper surface of the second housing, which is inconvenient.

  For this reason, it is proposed to slide in a side view curved shape, but since the compression spring is difficult to bias the first housing and the second housing in a curved shape, It is necessary to provide another mechanism that can move in a direction orthogonal to the sliding direction of the straight operation unit, and the structure becomes complicated.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a portable device that can be reduced in space and can be slid in a curved shape with a simple structure.

  In order to achieve the above object, a portable device according to the present invention includes a first housing and a second housing, and the first housing and the second housing can be relatively slid in a state of being overlapped with each other.
