2. Description of the Related Art Conventionally, a battery pack has been used for various portable electronic devices, and various efforts have been made to reduce the size or the thickness. Therefore, in a personal computer (hereinafter referred to as a PC), particularly, a reduction in thickness has been promoted, so that it is necessary to reduce the thickness of the battery pack itself and to save space in a storage portion in the main body.

Therefore, as disclosed in Japanese Patent Laid-Open No. 6-4178, a method has been proposed in which the battery pack is stored from the side of the PC body.

[0004]

The prior art disclosed in the above publication has a structure in which the battery pack is attached and detached from the side surface of the electronic device body, and the thinning of the PC body is a prerequisite, and the battery pack itself is considerably It must be thin.

Therefore, the present invention proposes a battery pack device for electronic equipment having a novel structure, which is not particularly restricted by the thinning of the PC body and the battery pack.

[0006]

According to the present invention, a recess for accommodating a battery pack is provided on one surface of a PC body, and a pair of electrodes for a battery and a detection terminal for a sensor are provided on the inner wall of the recess.
A spring for pressing the battery pack is fixed to the inner wall on the side different from the electrodes and the detection terminals, and a slide holding piece is attached to the inner wall on the side different from the side on which the spring is fixed and a holding notch is provided. The battery pack is provided with a projecting piece and a locking hole that are fitted to the tips of the holding notch and the slide holding piece, respectively.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings.
2 is an exploded perspective view of a main part of the device, FIG. 2 is a cross-sectional view of a main part of the device when a battery pack is about to be mounted on a PC body, and FIG. FIG. 4 is a bottom view showing a state in which the PC main body of the apparatus is viewed from the bottom, and FIG. 5 is a plan view of a battery pack of the apparatus.

In the drawing, 1 is a PC main body composed of an upper surface 2 and a lower portion 3, 4 is a battery terminal 5 and a sensor which are respectively connected to a battery electrode and a sensor (for detecting the voltage across the battery: not shown). A battery pack having a terminal 6 for battery, 7 is a battery connecting terminal 8 and a detecting terminal 9 which are respectively coupled to a battery terminal of the battery and a terminal for the sensor, and the battery pack is provided on the inner wall on the front side of the opening. A recess for storing a battery pack, to which a spring 10 for urging the battery is fixed, 11 is slidably attached to the lower part of the PC body and has a claw piece 12, 13 is a notch for holding. Reference numeral 14 is a coil spring for urging the slide holding piece, 15 and 16 are engaging holes and projecting pieces that fit into the slide holding piece and the holding notch, respectively, and 17 is a spring fall prevention pusher. For example the plate, 18 shows the key top.

The method of storing the battery pack in the PC body in the battery pack device of the present invention will be described below. First, referring to FIG. 1, the recess 7 for storing the battery pack provided in the lower portion 3 of the PC body 1 will be described. The battery pack 4 is housed by pushing it in the direction of the arrow shown in FIG. 2 against the elasticity of the spring 10.

At this time, the projecting piece 16 provided on the battery pack 4 is provided in the holding notch 13 provided on the inner wall adjacent to the inner wall.
When the battery terminal 4 side of the battery pack 4 is pressed after the insertion, the claw piece 12 provided at the tip of the slide holding piece 11 moves in the direction of arrow A in FIG. 1 against the elasticity of the coil spring 14, and FIG. As shown, the battery pack 4 is housed in the recess 7, and the slide holding piece 11 is indicated by the arrow B.
The claw piece 12 engages with the engagement hole 15 of the battery pack 4 by moving in the direction by the elasticity of the coil spring.

On the other hand, when the battery pack is removed from the PC body, the slide holding piece 11 is attached to the coil spring 1.
4 is moved in the direction of the arrow A in FIG. 1 against the elasticity of 4 to release the engagement between the claw piece 12 and the engagement hole 15 of the battery pack 4, the elasticity of the spring 10 mounted in the recess 7 is changed. The battery pack 4 is pushed out to the state shown in FIG.

Therefore, in FIG. 2, the battery pack 4 is
The battery pack 4 can be removed from the lower portion 3 of the PC body 1 by grasping the right side of the battery pack.

[0013]

According to the present invention, a recess is provided in the electronic device and the inner wall of each of the recesses is used as a battery connection terminal, a sensor connection detection terminal, and a battery pack biasing spring.
Since the slide holding piece and the holding notch are provided on each inner wall and the battery pack side is provided with the battery terminal, the sensor terminal, the engaging hole, and the projecting piece, the electronic device body and the battery pack can be made thinner. In addition, since the battery pack can be easily attached and detached, it is possible to smoothly replace the battery pack with a spare one.
