Abstract

An electronic apparatus comprises a battery pack that comprising a first battery cell and a second battery cell that are arranged in a first direction and store energy for enabling operation of electronic components; and a battery holder that houses the battery pack. The battery holder comprises a projecting part in a first face that configures the battery holder and covers the battery pack while the battery pack is provided with a slit that is fitted with the projecting part in a second face that is opposed to the first face. Furthermore, the first direction intersects a boundary direction extending between the first battery cell and the second battery cell, and the slit is formed to extend along the first direction in the second face.

Claims

1. An electronic apparatus comprising:

a battery pack that comprising a first battery cell and a second battery cell that are arranged in a first direction and store energy for enabling operation of electronic components; and

a battery holder that houses the battery pack,

wherein the battery holder comprises a projecting part in a first face that configures the battery holder and covers the battery pack;

wherein the battery pack is provided with a slit that is fitted with the projecting part in a second face that is opposed to the first face;

wherein the first direction intersects a boundary direction extending between the first battery cell and the second battery cell,

wherein a longitudinal direction of the first and second battery cells is parallel to the boundary direction, and

wherein a longitudinal direction of the slit is parallel to the first direction in the second face.

2. The electronic apparatus of claim 1,

wherein the slit is formed so as to avoid interference with the first battery cell and the second battery cell.

3. The electronic apparatus of claim 1,

wherein the first battery cell and the second battery cell have cylindrical shapes.

4. The electronic apparatus of claim 1, further comprising:

a wall positioned between the first battery cell and the second battery cell and facing the projecting part inside the battery pack.

5. An electronic apparatus comprising:

a battery pack that includes a first battery cell and a second battery cell and that has a slit that extends along an arrangement direction of the first battery cell and the second battery cell; and

a case that comprises a face portion provided with an projecting part and that houses the battery pack at a position where the projecting part fits into the slit,

wherein the arrangement direction intersects a boundary direction extending between the first battery cell and the second battery cell,

wherein a longitudinal direction of the first and second battery cells is parallel to the boundary direction, and

wherein a longitudinal direction of the slit is parallel to the arrangement direction.

6. The electronic apparatus of claim 5,

wherein the slit is formed so as to avoid interference with the first battery cell and the second battery cell.

7. The electronic apparatus of claim 5,

wherein the first battery cell and the second battery cell have cylindrical shapes.

8. The electronic apparatus of claim 5, further comprising:

a wall positioned between the first battery cell and the second battery cell and facing the projecting part inside the battery pack.

9. An electronic apparatus comprising:

a battery pack that includes a first battery cell and a second battery cell and is provided with a first slit that extends along a boundary between the first battery cell and the second battery cell in a first direction crossing an arrangement direction of the first battery cell and the second battery cell and a second slit extending in a second direction perpendicular to the first direction;

a case that comprises a battery holder that houses the battery pack; and

a projecting part that projects from a face of the battery holder to a side of the battery pack and is positioned within the second slit in a state where the battery pack is housed.

10. The electronic apparatus of claim 9, wherein the first slit is formed so as to avoid interference with the first battery cell and the second battery cell.

11. The electronic apparatus of claim 9, wherein the first slit is formed so as to pass through regions that are obtained in a face of the battery pack when positive pole terminals of the first battery cell and the second battery cell are projected in the direction crossing the arrangement direction, the face of the battery pack opposed to the face of the battery holder.

12. The electronic apparatus of claim 9, wherein the first battery cell and the second battery cell have cylindrical shapes.

13. The electronic apparatus of claim 9, further comprising a wall positioned between the first battery cell and the second battery cell and facing the projecting part inside the battery pack.

14. The electronic apparatus of claim 9, wherein the second slit extends in the arrangement direction of the first battery cell and the second battery cell is provided at a position crossing the first slit.

15. The electronic apparatus of claim 14, wherein the second slit is positioned along a boundary with the first battery cell and the second battery cell on one side of the boundary and a third battery cell positioned on another side of the boundary.

16. The electronic apparatus of claim 9 further comprising a second projecting part extending along the boundary between the first battery cell and the third battery cell.
