Abstract

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.

Claims

1. Electronic equipment, comprising:

a. housing that has an opening to which a battery unit is insertable;

an operation portion that allows operations of attaching/detaching the battery unit;

a battery holding portion that holds the battery unit;

a battery attachment portion that is provided with the operation portion and the battery holding portion,

wherein the battery holding portion is disposed between the operation portion and the opening in the battery attachment portion.

2. The electronic equipment according to claim 1, further comprising battery locking means capable of locking the battery unit arranged in the battery attachment portion,

wherein the battery locking means includes:

the operation portion arranged displaceably on one principal face of the housing and capable of locking the battery unit; and

a switch provided with a switch lever biased in one direction, the switch lever biasing the operation portion in one direction.

3. The electronic equipment according to claim 2, further comprising:

a light-emitting element that emits light when the switch is shifted to an ON state; and

remaining capacity detection means that detects a remaining capacity of the battery unit,

wherein, when detecting the shift of the switch to the ON state, the remaining capacity detection means causes the light-emitting element to emit light in accordance with the remaining capacity of the battery unit.

4. The electronic equipment according to claim 3, to/from which a plurality of battery units are attachable/detachable.

5. The electronic equipment according to claim 2,

wherein the battery attachment portion includes a first battery attachment portion and a second battery attachment portion,

the battery locking means is arranged between the first battery attachment portion and the second battery attachment portion, and includes a first holding portion capable of locking a battery unit attached to the first battery attachment portion and a second holding portion capable of locking a battery unit attached to the second battery attachment portion.

6. The electronic equipment according to claim 5,

wherein the battery locking means includes a coupling portion that couples the first holding portion and the second holding portion,

the coupling portion is formed with a plurality of holes, and

a part of the housing engages with at least one hole among the plurality of holes.

7. The electronic equipment according to claim 1,

wherein the battery attachment portion is formed with concave portions in a pair of inner faces thereof opposed to each other, and

the battery unit is formed with protrusions capable of engaging with the concave portions.

8. The electronic equipment according to claim 1,

wherein the battery attachment portion is formed with protrusions on a pair of inner faces thereof opposed to each other, and

the battery unit is formed with concave portions capable of engaging with the protrusions.
