Description

Physical projector

The invention relates to a physical projector.

The conventional physical projector is an electronic product having a camera module and an image output port. In use, the camera module can take a picture and use the image output to transmit the picture to an external display device, such as a large-size TV or projector. Since the physical projector needs to have a built-in camera module, it is expensive and mostly used for teaching.

On the other hand, most of the docks that are connected to smart phones only have the function of placing a mobile phone and connecting a computer. Although the stand of the mobile phone can be equipped with a card reader and a USB interface, the video data of the mobile phone cannot be output to the external display device through the stand.

In addition, when users have a demand for a physical projector and a video conferencing system, it is necessary to purchase two products at the same time and spend a large amount. In addition, during installation, the physical projector and the video conferencing system need to be respectively connected to the display device, which not only causes waste of the wire, but also wastes more space and installation time.

One aspect of the present invention is a physical projector.

According to an embodiment of the invention, a physical projector includes a housing, a handheld device, a main frame, a support frame and a connector. The accommodating portion has a positioning groove and an opening. The handheld device is detachably positioned in the positioning slot. The handheld device has a camera module. The camera module is exposed to the opening. The main unit has an image output port. The support frame is located between the receiving portion and the main frame. The support frame is pivotally connected to the receiving portion. The connector is electrically connected to the handheld device and the main frame to transmit the image data captured by the camera module to the image output port.

In an embodiment of the invention, the physical projector further includes a light source. The light source is pivotally connected to the support frame.

In an embodiment of the invention, the connector has a control module. The main unit contains a touch screen. The touch screen is electrically connected to the control module for controlling the handheld device.

In an embodiment of the invention, the positioning groove and the opening are located on opposite surfaces of the receiving portion.

In an embodiment of the invention, the positioning groove is located on a surface of the accommodating portion, and the opening is located at the other surface of the accommodating portion perpendicular to the surface.

In an embodiment of the invention, the main body base has a plug for connecting to a power source. The connector has a power supply interface. The power supply interface is electrically connected to the plug and the handheld device.

In an embodiment of the invention, the connector has an image transmission interface. The image transmission interface is electrically connected to the image output port and the handheld device.

In an embodiment of the invention, the physical projector further includes a cut Replacement lens module. The switching lens module is rotatably disposed on the accommodating portion. The switched lens module has a plurality of lenses, and one of the lenses is aligned with the opening of the housing.

In an embodiment of the invention, the physical projector further includes a sleeve. The sleeve is disposed on the accommodating portion and aligned with the opening of the accommodating portion for connecting the eyepiece of the microscope.

In an embodiment of the invention, the mainframe has a memory card slot for accommodating the memory card and storing the image data captured by the camera module through the memory card.

In the above embodiment of the present invention, the accommodating portion has a positioning groove and an opening, and the handheld device is detachably positioned in the positioning groove. In use, the handheld device can be placed into the positioning slot such that the camera module of the handheld device is exposed by the opening of the receiving portion. Then, the accommodating portion can be pivoted on the support frame to adjust the shooting direction of the camera module. In this way, the camera module can capture the object to be viewed (such as a file on the desktop) or a person through the opening of the accommodating portion, and the connector transmits the image data captured by the camera module to the image output port. When the image output is connected to an external display device, the display device can display the camera module to capture an image of the object or person to be viewed.

The physical projector can have the ability to capture a subject or a person by adjusting the shooting direction of the camera module, and thus has the functions of a conventional physical projector and a video conferencing system. In addition, the camera module of the physical projector is a component of the handheld device, so the physical projector after omitting the handheld device has a simple structure and can save cost.
