JP 2000-284362 A

However, in the structure described in Patent Document 1, since the handle is stored in the storage portion when the handle is positioned at the storage position, the handle is gripped and rotated from the storage position toward the grip position. There is a problem that is difficult.
In particular, in the structure described in Patent Document 1, the handle is attached to the lower case located on the installation surface side of a desk or the like on which the projector is installed in the exterior housing. That is, when the user rotates the handle from the storage position toward the gripping position, the user needs to pull up the handle by putting a finger between the handle and the desk and hooking the handle. However, since the gap between the handle and the desk is small, it is difficult to put a finger into the gap.

  The objective of this invention is providing the projector which can move a handle to a holding position easily and can improve the usability of a handle.

  A projector according to the present invention is a projector that forms and projects an image according to image information, and includes an exterior casing that constitutes an exterior, and a handle for carrying the projector, and the handle includes the exterior casing. It is attached to the body so as to be movable to a gripping position protruding from the outer surface of the outer casing or a storing position stored in the outer casing, and the handle is located on the outer surface of the outer casing. And a recess for storing at least a part of the handle and a recess for extraction communicating with the recess for storage.

In the present invention, a housing recess and an extraction recess communicating with the housing recess are formed on the outer surface of the exterior housing. This allows the user to place the handle from the storage position by inserting a finger into the extraction recess and hooking the handle while the handle is positioned at the storage position and at least part of the handle is stored in the storage recess. It can be easily moved toward the gripping position. Therefore, the usability of the handle can be improved.
In addition, even when the handle and the installation surface of the desk or the like are close to each other when the handle is positioned at the storage position, as described above, the handle can be easily moved from the storage position toward the gripping position. Since it can be moved, the freedom degree of the attachment position of the handle with respect to the outer surface of an exterior housing | casing can be improved.

In the projector according to the aspect of the invention, the storage recess is formed in one side wall portion of the exterior housing, and the extraction recess is another side wall adjacent to the one side wall portion from the one side wall portion in the exterior housing. It is preferable that it is formed so as to straddle the storage recess.
By the way, since the projector is reduced in size and weight, the portability can be improved, but it is easily stolen. Therefore, in order to prevent the projector from being stolen, it is conceivable to mechanically prevent the projector from being stolen by winding a metal wire or chain around the handle.
However, in a state where a wire or a chain is wound around the handle, the handle cannot be positioned at the storage position because the wire or the chain is caught in the storage recess. That is, in the above-described state, the handle is not stored in the storing recess, so that the appearance is poor.

  In the present invention, the recess for extraction is formed so as to straddle the recess for storage from one side wall portion to the other side wall portion adjacent to the exterior casing. Thus, even when the wire or the chain is wound around the handle, the wire or the chain can be stored in the take-out recess without being caught by the storage recess when the handle is positioned at the storage position. That is, even when a wire or a chain is wound around the handle, the handle can be stored in the storage recess, and a projector having a good appearance can be configured.

In the projector according to the aspect of the invention, it is preferable that the handle is formed with an inclined surface that is inclined so as to be separated from the take-out concave portion toward the bottom portion of each concave portion.
In the present invention, the above-described inclined surface is formed on the handle. As a result, the user can easily hook the finger on the handle (inclined surface) after inserting the finger into the take-out recess when the handle is positioned at the storage position, and the handle is moved from the storage position to the gripping position. Can be moved more easily.

  In the projector according to the aspect of the invention, the projector includes an air filter that captures dust contained in the air introduced into the exterior casing, and a filter cover that protects the air filter, and the filter cover is provided on an outer surface of the exterior casing. It is preferable that a concave portion for the cover is formed, and the concave portion for extraction is formed so as to communicate with the concave portion for cover.

  In the present invention, the extraction recess is formed to communicate with the cover recess described above. Thus, for example, even when the filter cover and the handle are respectively attached to the exterior housing at positions close to each other, the user inserts his / her finger into the extraction recess and removes the filter cover. The filter cover can be easily removed from the exterior housing by hooking on the side end. Therefore, the filter cover can be removed from the outer casing without moving the handle to the gripping position, for example, and the air filter can be easily replaced.
