There is provided a foldable electronic apparatus in which first and second casings are pivotally mounted by a bearing portion so as to be freely rotatable and these casings are automatically opened until a predetermined opening angle and then further manually opened. In the electronic apparatus of the present invention, the first and second casings (), () are freely rotatably connected to each other (pivotally mounted) through a bearing portion (). An opening/closing device () for automatically opening the first and second casings (), () until a predetermined opening angle by operating a push button () is secured to the bearing portion. The opening/closing device () includes a mechanism for opening the casings until a larger opening angle exceeding the predetermined opening angle, and the first and second casings (), () can be manually opened till a larger opening angle.

Electronic device

The present invention relates to a toner bottle having a body with a convexly-shaped spiral rib continuously formed on the inside surface thereof and a tip with an opening for toner to flow therefrom. A section for joining the body and the tip includes a first circular face having a slope convex portion that slopes toward the inside, and a second circular face having a toner pump-up portion, the diameter of which is approximately same as that of the body. There is a shutter rotatably disposed on the tip to normally close the opening. The shutter has an opening that fits over the tip opening when the toner bottle is rotated inside the shutter. The shutter may be made of elastic material, and has arcs of different thicknesses. A thicker one of the arcs is used to keep the tip opening closed except when being used in a toner supplying apparatus. The toner bottle allows the toner to flow in a continuous manner, and prevents users from dirtying their hands when replacing toner bottles.
