As shown in FIGS. 3 to 5, the present embodiment is a projector 10 having a reflecting device, comprising: a projector body 20 and a reflecting device 30.

The projector body 20 is a projector including a first surface 21 and a second surface 22, wherein the first surface 21 is a plane on the front side of the projector body 20, and a projection lens 23 is disposed on the first surface 21. For projection screen display, for example, can be projected to a wall or curtain. The second surface 22 of the projector body 20 may be provided with a connector 24, wherein the second surface 22 may be an inner surface formed by an outer edge portion of the upper surface of the projector body 20 extending upward.

The connector 24 can be in the form of an embedded connector for directly engaging the connector 24 for connection in the form of the mobile device 200. The mobile device 200 can transmit projection information to the projector body 20 through the connector 24. The mobile device 200 can be a smart phone. Therefore, when the smart phone is connected to the projector body 20 through the connector 24, the operation content displayed by the smart phone can be projected through the projector body 20.

The reflecting device 30 is disposed on the first surface 21 and disposed adjacent to the projection lens 23 for changing the path of the projected image by the reflecting device 30, wherein the reflecting device 30 comprises: The cover 31 and a mirror 33.

The cover plate 31 can be a plate body, wherein the cover plate 31 is coupled to the first surface 21 by a rotating shaft 32 so that the cover plate 31 can cover the projection lens 23 when closed to protect the projection lens 23 and prevent dust. The cover plate 31 can be rotated by the rotating shaft 32 by being dropped into the projection lens 23 or by the damage caused by the collision, and the angle at which the cover 31 can be opened and closed can be freely adjusted. The material of the cover plate 31 may be a higher density plastic material or a metal material. Since the material of the cover plate 31 is hard, it can be used to protect the projection lens 23 to extend the service life of the projection lens 23.

The mirror 33 is disposed inside the cover 31, and when the cover 31 is closed, the mirror 33 is located at a position opposite to the projection lens 23. When the cover 31 is opened and closed to a specific angle, the projected image projected by the projection lens 23 is reflected by the mirror 33 to the position to be projected. Therefore, when the mobile device 200 is coupled to the projector body 20, the user can adjust the angle of opening and closing of the cover 31 while the screen of the mobile device 200 is being touched, so that the projected image is reflected and reflected on the mobile device 200. The display is projected to the appropriate position.

As shown in FIGS. 5 to 9, in addition, the cover 31 may be disposed on the front side, the left side, the right side, or the upper side of the projection lens 23, and the projection screen may be projected longitudinally or laterally to a position to be projected. For example, when the user wants to project the projection screen to the front side, the rotating shaft 32 can be disposed on the upper side of the projection lens 23 such that the cover 31 is connected to the upper side of the projection lens 23, so that the mirror 33 reflects the projection image to the front side. When the user wants to project the projection screen to the left side, the rotating shaft 32 can be disposed on the right side of the projection lens 23 such that the cover 31 is connected to the right side of the projection lens 23 so that the mirror 33 reflects the projection image to the left side.

If the user wants to project the projection screen to the right side, the rotating shaft 32 can be disposed on the left side of the projection lens 23, so that the cover 31 is connected to the left side of the projection lens 23, so that the mirror 33 reflects the projection image to the right side; When the projection screen is to be projected onto the ceiling, the rotating shaft 32 can be disposed on the lower side of the projection lens 23 such that the cover 31 is connected to the lower side of the projection lens 23, and the mirror 33 reflects the projection image to the ceiling to reach the projector. The body 20 is capable of changing the effectiveness of the path of the projected picture.

The mirror 33 can be a convex mirror. When the projection lens 23 projects the projection image through the convex mirror, the convex mirror has an enlarged effect, so that the projection image is enlarged, so that the viewer can see the projection screen more clearly.
