Abstract
Inclined plane is provided at the tip of rotor cam. On the other hand, inclined planes are also provided in specific positions of stator cam. Because of this structure, in the specific positions, the inclined planes are in resilient contact with each other. Thus, the load is increased only in the specific positions without an increase in the load of spring. This structure can provide an opening and closing device capable of securely holding only desired positions without affecting the feel of opening and closing operation of the entire device, and electronic equipment using the device.
