Description

  The present invention relates to an imaging apparatus having a display unit that can be reversed and stored.

  In recent years, the power consumption of the imaging apparatus main body has been increasing due to the increase in functionality and technological progress. Similarly, in the display device connected to the imaging device, the power consumption increases as the brightness increases.

  Here, in the imaging device, the display device has a structure independent of the imaging device body, and thus cannot be directly connected to a cooling mechanism such as an air cooling fan or a cooling fin of the imaging device body. Therefore, it is difficult to cool a display device with high power consumption and high temperature. Therefore, it is desired to quickly establish an efficient display device cooling method. Here, as shown in Patent Document 1, a method of cooling the liquid crystal panel by arranging a Peltier element and a heat sink on the side of the display surface of the liquid crystal panel has been proposed.
