The electronic equipment disclosed in the present application realizes a battery attachment/detachment mechanism with the reduced number of components, by biasing a slide lever 11 to a protrusion position by a biasing force of a switch lever 13a of a switch 13. More specifically, in the electronic equipment disclosed in the present application, it is unnecessary to provide biasing means for biasing the slide lever 11 to the protrusion position in addition to the switch 13, the number of components is reduced as compared with the configuration provided with biasing means in addition to the switch. By reducing the number of components, the cost is reduced and the assembly time in assembling notebook computers is reduced, thereby improving workability in the assembly.
