Description

The present application is based on, and claims priority from JP Application Serial Number 2022-025692, filed Feb. 22, 2022, the disclosure of which is hereby incorporated by reference herein in its entirety. BACKGROUND 1. Technical Field The present disclosure relates to a display apparatus supporting stand and a projection system. 2. Related Art There has been known a projector that optically projects projection light onto a projection surface. There has been proposed an attachment member to which such a projector is attached to enable a posture of the projector to be manually adjusted (JP2018-72803A (Patent Literature 1)). However, in the attachment member disclosed in Patent Literature 1 described above, the periphery of the projector is surrounded in a box shape by a base member made of a plate material. Therefore, heat exhaust of the projector cannot be efficiently performed. SUMMARY According to an aspect of the present disclosure, there is provided a display apparatus supporting stand including: a fixing part configured to fix a display apparatus including a vent hole used for ventilation; and a plate material configured to support the fixing part in at least one of a first posture and a second posture. The plate material includes a first region opposed to the vent hole of the display apparatus when the display apparatus is fixed to the fixing part and the fixing part is in the first posture. The plate material includes a second region opposed to the vent hole of the display apparatus when the display apparatus is fixed to the fixing part and the fixing part is in the second posture. The plate material includes a first opening in the first region. The plate material includes a second opening in the second region. According to an aspect of the present disclosure, there is provided a projection system including: the display apparatus supporting stand described above; and the display apparatus. The display apparatus is a projector that projects projection light.

DESCRIPTION OF EXEMPLARY EMBODIMENTS An embodiment of the present disclosure is explained below with reference to the drawing. Note that, in the drawings referred to below, in order to clearly show components, some components are shown in different scales of dimensions. FIG. 1 is a perspective view of a projection system 1 including a display apparatus supporting stand, to which a projector 10 is attached, according to the embodiment viewed from an oblique front. FIG. 2 is a perspective view of the projection system 1 viewed from an oblique front at another angle. FIG. 3 is a front view of the projection system 1 viewed from the front. FIG. 4 is a side view of the projection system 1 in which a side surface plate including engaging holes is viewed from a side. The projection system 1 in this embodiment includes the projector 10 (a display apparatus) that projects projection light and a supporting stand 20 (the display apparatus supporting stand) on which the projector 10 can be set. The projector 10 set in the supporting stand 20 can be carried by moving the supporting stand 20 with, for example, human power. That is, the supporting stand 20 is used when, only by moving the supporting stand 20 to a desired position, projection light is projected onto, for example, a screen or a wall surface such as a ceiling surface or a side surface in a room by the projector 10 on the supporting stand 20 without replacing the projector 10 from the supporting stand 20 to another place. In the projector 10, a direction in which a projection lens 11 is disposed is referred to as front or a front side. A surface located on the front side in a housing of the projector 10 is referred to as a front surface. The projector 10 includes a front surface 10A, a rear surface 10B, a pair of side surfaces 10C, 10C, an upper surface 10D, and a lower surface 10E. In the projector 10, the rear surface 10B is a surface opposite to the front surface 10A. A direction in which the rear
