Abstract

An oscilloscope of the following type is disclosed. Even though a main unit of the oscilloscope is horizontally placed, a display can be adjusted at an optimal angle. Also, while the main unit remains in such a position, press buttons can be depressed stably. An operating section is covered in the case of carrying the oscilloscope and knobs of the operating section, and the like, can be kept out of the way, thereby not hampering portability. An oscilloscope casing is divided into a display section and an operating section. A part of the top surface of the main unit is lowered and the operating section is placed on the lowered surface. The display section doubles as a cover for the operating section and is pivotally fixed to the top surface of the main unit via a hinge so as to freely open and close. The display section has a display screen inside and forms the top surface of the main unit and covers the operating section outside when the display section is closed.
