  By the way, for example, there are 13-type notebook personal computers in which the battery pack is configured to be detachable without the use of a tool by the user, and those having a built-in battery pack that cannot be removed without using a tool.

  The battery pack that is assumed to be configured to be detachable from the notebook computer needs to be disposed in a region (rear part) extending from the center to the back surface of the lower housing in order to make the detachable mechanism simple. Further, in order to make the device appear thin, a thick battery is often arranged on the back side of the device.

  On the other hand, the built-in battery pack that is detachable does not need to be placed at the rear of the lower housing, but rather is an area from the center to the front, which is the part of the user's palm that operates the keyboard ( In the front part, it is better to arrange a battery pack that generates less heat than a high heat-generating part such as a CPU because it does not want to place a high heat-generating part (CPU: Central Processing Unit, cooling fan, etc.).

  However, when the battery pack is arranged at the front part of the lower housing, the distance between the motherboard and a component that should be arranged downward on the front surface of the lower housing becomes longer, and the wiring becomes longer. When the wiring becomes long, it may be difficult to store in the lower housing. Especially when the wiring is sandwiched between the battery pack and the lower housing, the lower housing may have a thin structure of tens of mm or less. difficult.

  The battery pack 31 will be described in the case of 6 cells. In the case of the battery pack 31, rectangular (eg, tile or sheet) secondary batteries 32c, 32b, 32d, and 32e are arranged in two rows and two columns in the center, and on both sides of the lower secondary battery column. The secondary batteries 32a and 32f are arranged one cell at a time and are stored in a convex planar shape. This is to reduce the thickness of the lower housing 11.

Here, the case of the battery pack 31 is formed in a gull wing shape as shown in FIG. That is, the secondary batteries 32a and 32f on both sides are arranged in the case so as to be higher than the central secondary batteries 32b to 32e (having a step h). The level difference h is set according to the height of the accommodating portion (a concave portion when viewed from the bottom, and a convex portion when viewed from the inside) of the rubber legs 15 disposed at the four corners of the bottom surface of the lower housing 11.
Since the step between the secondary battery 32a side and the secondary battery 32c side of the battery pack 31 is formed in the lower housing 11, a space is formed, and the motherboard and speakers 25L, 25R Wiring between can be performed.

On the front surface of the battery pack 31, protrusions 54aL, 54bL, 54aR, and 54bR are formed that protrude from the upper and lower surfaces of the case of the battery pack 31 and form grooves 53L and 53R for storing wiring. .
The protrusions 54aL and 54aR on the upper surface side are formed shorter than the width of the secondary batteries 32a to 32f in order to provide a gap for wiring.
The protrusions 54bL and 54bR on the lower surface side are longer than the protrusions 54aL and 54aR, and claws 52L and 52R are integrally formed at the ends of the protrusions 54bL and 54bR in parallel with the front surface of the case of the battery pack 31. The claws 52L and 52R are members for holding or hooking a part of the wiring.
Notches 55L and 55R are formed in the vicinity of the protrusions 54bL and 54bR on the lower surface side of the case of the battery pack 31. These notches 55L and 55R are notches for allowing wiring to pass therethrough.

The battery pack 31 has a lower surface corresponding to the secondary batteries 32 b to 32 e of the case in surface contact with the bottom surface 11 b of the lower housing 11, and a lower surface corresponding to the secondary batteries 32 a and 32 f of the case accommodates the rubber legs 15. The upper surface corresponding to the secondary batteries 32 a and 32 f of the case is in partial surface contact with the top plate 11 a of the lower housing 11.
