Even if it covers with the board 4, an external appearance shape does not become large and the appearance from an external appearance can be improved.

Here, a specific structure for making the AC power cord and connector pull-out direction variable will be described below.

First, the point to consider when changing the direction in which the AC power cord is pulled out is to consider the safety aspect by suppressing the possibility of disconnection and the like due to the load on the AC power cord. For this purpose, it is necessary to change the pull-out direction of the connector of the AC power cord instead of simply bending the AC power cord and changing the pull-out direction. Therefore, the direction of the insertion surface of the AC inlet for inserting the connector is made variable. That is, the present embodiment relates to an AC inlet mounting structure in which an AC power cord connector can be inserted, and the direction thereof is variable. When changing the direction of the AC inlet, it is necessary to consider the safety aspect so that no load is generated on the internal wiring cable connected to the AC inlet, as described above.

It is the 3rd page view seen from II) and (III). That is, they are a front view (I) viewed from the (I) direction of (A), a top view (II) viewed from the (II) direction, and a side view (III) viewed from the (III) direction. FIG. 6 is a cross-sectional view of the front view (I) and the top view (II) shown in FIG. 6B is a cross-sectional view taken along the line AA of the top view (II) of FIG. 6A, and FIG. 6D is a front view of the front view (I) of FIG. 6C.

As shown in (II) and (III) of FIG. 5B, the cable 10 connected to the AC inlet passes through the hollow portion of the AC inlet support member 6, and the shaft portion 7 of the AC inlet support member 6. Is wired inside the projector device. Specifically, as shown in FIG. 6D, the cable 10 connected to the AC inlet is fixed to the AC inlet support member 6 by the fastener 11, passes through the hollow portion of the AC inlet support member 6, and passes through the shaft. It is configured to pass through the hollow portion of the portion 7. Therefore, even if the AC inlet support member 6 rotates, the cable 10 is not subjected to a load.

FIG. 7 shows an explanatory diagram when the AC inlet according to the present embodiment is oriented in the horizontal direction. FIG. 7A is a perspective view of the projector device in which the AC inlet is disposed as seen from obliquely above the back, and FIG. 7B is a three-view diagram seen from the three directions shown in FIG. FIG. 8 shows an explanatory diagram when the AC inlet in the present embodiment is oriented in the vertical direction. Similarly to FIG. 7, FIG. 8 (A) is a perspective view of the projector device in which the AC inlet is disposed as seen from obliquely above the back, and FIG. 8 (B) is seen from the three directions shown in FIG. 8 (A). FIG. Here, as shown in FIG. 8, the AC inlet 5 has a ceiling-mounted direction, that is, a direction toward the lower side of the figure, that is, the lower side of the projector device, when the AC inlet supporting member 6 is rotated by the shaft portion 7. The direction can be changed to the ceiling side. The shaft support member 8 is also provided with a notch on the lower side of the projector device so that the connector of the AC power cord can be inserted into the AC inlet.

As described above, in this embodiment, the AC inlet supporting member that holds the AC inlet is rotatably supported, and the cable connected to the AC inlet is not subjected to a load during rotation. There is no worry about disconnection of connected cables, and safety against electric leakage can be secured.

The structure of the AC inlet mounting portion described above is not limited to this, and an AC inlet support member that holds the AC inlet and a rotation that the AC inlet support member is rotatably supported by the projector device. What is necessary is just to become the double structure provided with the member. That is, in the above-described embodiment, the rotating member is the shaft portion 7 that constitutes the AC inlet support member 6, the shaft support member 8 that rotatably supports the shaft portion 7, and the shaft portion 7 that rotates to the shaft support member 8. It corresponds to the shaft engaging member 9 that engages with each other.

Also, although the AC inlet is in a variable direction, there are basically two projector devices: table installation and ceiling mounting, so it is only necessary to switch between at least two directions. That is, the horizontal direction and the vertical lower direction of the projector device. In terms of safety, it is desirable to fix the direction so that the AC inlet does not rotate in a state where the AC power cord connector is inserted into the AC inlet and power is supplied. Therefore, for example, two protrusions may be provided on the shaft portion, the position thereof may be approximately 90 °, and the protrusion may abut against the shaft support member to be locked and fixed in two directions. Alternatively, the position of the protrusion may be detected by a switch sensor, and the current may not be supplied unless the position is at a predetermined angle. Further, a double shaft configuration may be used so as to be stably fixed at two locations.

As described above, the present embodiment is a projector apparatus corresponding to a ceiling installation in which the installation state is a table installation state and the table installation state is turned upside down and suspended from the ceiling.

The AC inlet mounting portion includes an AC inlet supporting member that supports the AC inlet, and a rotation in which the AC inlet supporting member is rotatably supported by the projector apparatus. It is set as the structure which consists of a moving member.

Therefore, according to the present embodiment, the direction of the connector insertion surface of the AC inlet can be changed according to the installation status of the projector apparatus. Therefore, for example, in the case of ceiling mounting, by changing the direction of the connector insertion surface of the AC inlet to the vertical direction, the drawing direction of the connector and the AC power cord can be set to the ceiling side. Therefore, even if the cover is covered with a blindfold, the external shape does not increase and the appearance from the external appearance can be improved.

In this embodiment, the cable for video signal input and communication signal input is made into a single line or wireless to make the external wiring look clean, and the power cord does not protrude from the surface where the AC inlet of the projector device is arranged, An example of a projector device that can improve the appearance from the appearance without increasing the appearance shape will be described.

FIG. 10 is an enlarged view of the AA portion in the rear view of FIG. FIG. 11 shows an enlarged view of a BB portion in the bottom view of FIG. FIG. 12 is an enlarged perspective view of the CC portion in the bottom view of FIG.

As shown in FIGS. 10, 11, and 12, the projector device in the present embodiment is arranged at a position where the AC inlet 5 is deeper than the rearmost surface 20 of the projector device.

FIG. 13 shows a usage state of the back surface of the projector apparatus in the present embodiment. As shown in FIG. 13, the connector 3 of the AC power cord 2 inserted into the AC inlet 5 extends in the lateral direction and does not protrude from the rearmost surface 20 of the projector device. Therefore, even if it covers with the blindfold board 4, an external appearance shape does not become large and the appearance from external appearance can be improved.
Similarly, the signal line 30 is also made, for example, as a single line so that the signal line 30 extends from a position deeper than the rearmost surface 20 of the projector apparatus. The appearance shape does not increase, and the appearance can be improved. Note that the signal line may be wireless.
