 to the first aspect. In addition, the panel is provided with an engaging body presser portion capable of pressing the unit engaging body against the elastic member along with a pivotal movement of the panel.
This allows the second aspect of the present invention to function in an equivalent manner to the aforementioned first aspect of the invention as well as to move the unit engaging body by the pivotal movement of the panel.
More specifically, pivotal movement of the panel in one direction (or opening the panel) causes the engaging body presser portion of the panel to push the unit engaging body, thereby allowing the unit engaging body to be withdrawn from the engaging through-hole. This allows the device unit to be easily disengaged from the apparatus main body.
The device unit housing apparatus according to a third aspect of the invention includes an apparatus main body provided with an engaging through-hole formed therein for accommodating a device unit or an engaged subject, and a unit engaging mechanism provided on the device unit. The unit engaging mechanism provided on the device unit is disposed, with the device unit being accommodated in the apparatus main body, adjacent to an opening of the apparatus main body for accommodating the device unit.
Furthermore, the unit engaging mechanism includes a unit engaging body movable and having a unit engaging main body engageable with the engaging through-hole, an elastic member capable of always pressing the unit engaging body against the engaging through-hole, and a panel spaced by a predetermined distance apart from the unit engaging main body and pivotable with respect to the device unit. Still furthermore, the unit engaging main body is provided with a projection oriented toward the panel. The panel is provided with an engaging body presser portion capable of engaging the projection of the unit engaging body along with a pivotal movement of the panel and pressing the unit engaging body against the elastic member. Here, the engaging body presser portion is
