ABSTRACT:
A projection display apparatus comprising a floppy disk drive device and floppy disk insertion opening in an appropriate arrangement is provided. A power supply unit, over which is disposed a floppy disk drive unit, is provided at the back of the projection display apparatus. The floppy disk drive unit is positioned offset to the left side of the projection display apparatus. A floppy disk (FD) insertion opening is positioned in a side wall at the left side of the exterior case of the projection display apparatus. An FD drive circuit board is positioned horizontally to the right of the floppy disk drive unit and slightly overlapping a drive control circuit board such that the electrical connections between the drive control circuit board and the FD drive circuit board can be made in this overlapping area. The side wall in which the floppy disk insertion opening is provided includes the operating panel in which the input/output terminals and operating switches are also disposed. This arrangement enables the floppy disk drive unit to be provided inside the projection display apparatus without using specific separate mounting members or reinforcing members therefor, and enables electrical connections between the power supply unit and control circuit board to be established via the FD drive circuit board without using separate wiring or harnesses. Operability is also improved because the floppy disk insertion opening is provided at the operating panel side.
