BACKGROUND OF THE INVENTION
The present invention relates to a battery case and an electric device including the battery case.
[0002]
[Prior art]
FIG. 8 is a plan view of a conventional general battery case (8), and FIG. 9 is a cross-sectional view of FIG. 8 taken along the plane including the line AA. The battery case (8) is provided with two storage chambers (88) and (88) arranged side by side, and a dry battery (9) is stored in each storage chamber (88). In the storage chamber (88), terminal pieces (81) and (82) are provided so as to face both electrodes (90) and (91) of the dry battery (9). The peripheral surface of the dry battery (9) is the dry battery (9). Is received by the peripheral wall (84) of the storage chamber (88) extending in the longitudinal direction. One terminal piece (81) is formed by bending a leaf spring, and presses and contacts the dry battery (9) toward the other terminal piece (82). In this state, power is supplied from the dry battery (9) to the terminal pieces (81) (82).
[0003]
[Problems to be solved by the invention]
Some devices using the battery case (8) are required to be thin, and the battery case (8) also needs to be thin. The applicant has conceived that as a means for reducing the thickness, the bottom of the storage chamber (88) is opened and the lower end of the dry battery (9) is lowered.
However, when the dry battery (9) is used for a long time or when old and new dry batteries (9) are used in combination, the internal electrolyte may leak from the dry battery (9). In this case, the electrolyte solution from the dry battery (9) may fall from the opening and damage other devices located below the battery case (8).
An object of the present invention is to achieve both reduction in thickness of a battery case and prevention of dropping of an electrolyte leaked from a dry battery.
[0004]
[Means for solving the problems]
An opening (85) into which the lower end of the dry battery (9) is fitted is formed in the peripheral wall (84) that receives the peripheral surface of the dry battery (9), and the dry battery (9) is provided below the opening (85). A protective sheet (95) for absorbing the leaked liquid is provided.
[0005]
[Action and effect]
The dry battery (9) is stored in the battery case (8) and the lower end fits into the opening (85). That is, since the lower end of the dry battery (9) falls into the opening (85), the height from the lower end of the battery case (8) to the upper end of the dry battery (9) can be reduced. Thereby, a battery case (8) can be reduced in thickness. In addition, a protective sheet (95) is provided below the opening (85), and even if the electrolyte leaked from the dry battery (9) flows through the opening (85), the protective sheet (95) Since it is absorbed, even if another device is positioned below the battery case (8), there is no possibility of damaging the device.

[0008]
FIG. 2 is a rear view of the cabinet (1). Terminals (10) and (11) are provided below the display unit (2) on the rear surface of the cabinet (1). The terminals (10) and (11) are specifically IEEE1394 specification terminals and USB terminals. When the IEEE1394 cable and USB cable are attached to the terminals (10) and (11) and the power button (83) is operated. It is detected that the cable is connected to the terminals (10) and (11). A power cord terminal (12) to which an AC power cord is connected is provided on the side of the terminals (10) and (11).
[0009]
FIG. 3 is a front sectional view of the cabinet (1). On the inner bottom surface of the cabinet (1), a circuit board (15) is provided below the disk recording or reproducing device (7) and the card storage unit (3), and the terminals (10) (11) The power supply IC and the disk drive IC are arranged on the circuit board (15). The disc recording or reproducing device (7) is formed to have a thickness substantially equal to the thickness of the battery case (8) and the card storage portion (3) overlapped.
4 is a cross-sectional view of the disk recording or reproducing device (7) as viewed from the direction B of FIG. The disk recording or reproducing device (7) includes a mechanical deck (5) for recording data signals on the disk (60) and reproducing data signals from the disk (60).

During reproduction, the recording head (53) is turned off and a beam is emitted from the pickup (51) to reproduce the data signal. If the lid (70) is inadvertently opened during recording or playback of the data signal, it will not be recorded or played back smoothly.Therefore, even if the eject button (72) is slid during the recording or playback of the data signal, the lid The device (70) does not open. Details of this device have been previously described in Japanese Patent Application No. 2000-166959 (unpublished invention) by the applicant, and will not be described.
[0010]
FIG. 5 is a plan view of the battery case (8) with the lid (80) removed, FIG. 6 is a cross-sectional view of the battery case (8) cut along the plane including the CC line, and FIG. FIG. 6 is a cross-sectional view of the battery case (8) cut away at the plane including the DD line. The battery case (8) is partitioned into four storage chambers (88), (88), (88), and (88), and an AA dry battery (9) is provided in each storage chamber (88). The four dry batteries (9), (9), (9) and (9) are arranged in parallel to each other, but the dry batteries (9) housed in the battery case (8) are not limited to four. At both ends of the storage chamber (88), terminal pieces (81) and (82) are provided corresponding to both poles (90) and (91) of the dry battery (9), and the shapes of the terminal pieces (81) and (82) are provided. Is the same as shown in FIG.
Of the four storage chambers (88), (88), (88), and (88), the front two storage chambers (88) and (88) are opposed to the card storage portion (3). In order to reduce the thickness of the cabinet (1), it is necessary to reduce the total thickness of the card storage part (3) and the battery case (8). In order to make the battery case (8) thinner, the following measures are taken.
[0011]
An opening (85) into which the lower end of the dry battery (9) is fitted is opened on the lower surfaces of the two storage chambers (88) and (88) in front of FIG. 5, and the dry battery (9) is provided as shown in FIG. The side portion is supported by the peripheral wall (84) of the storage chamber (88) with the lower end portion falling into the opening (85). The height H1 from the lower surface of the storage chamber (88) to the upper end of the dry cell (9) can be made lower than the conventional configuration H (see FIG. 9), and the battery case (8) can be made thinner.
Since the two storage chambers (88) and (88) on the back side in FIG. 5 do not face the card storage section (3), it is not necessary to reduce the thickness. Therefore, as shown in FIG. 7, without providing the opening (85), the opposing peripheral walls (84) and (84) are connected by the connecting plate (86) to increase the strength.
[0012]
When the dry battery (9) is used for a long time or when old and new dry batteries (9) are used in combination, dry batteries with different performance, such as manganese batteries and alkaline batteries, are used. The electrolyte may leak. In this case, the electrolytic solution from the dry battery (9) may fall from the opening (85) and damage the card storage portion (3) located below the battery case (8).
Therefore, as shown in FIG. 6, a protective sheet (95) that absorbs the electrolytic solution is attached to the lower side of the opening (85) of the storage chambers (88) and (88) located in front, so that the electrolytic solution is The battery case (8) is prevented from falling. The protective sheet (95) is formed of a nonwoven fabric such as felt, for example, but it goes without saying that it may be made of other materials. The protective sheet (95) is thin and hardly affects the thickness of the battery case (8).
In the two storage chambers (88) and (88) on the back side, through holes (87) are opened below the terminal pieces (81) and (82), and the electrolyte leaked from the dry battery (9) is stored in the storage chamber ( 88) Prevents it from accumulating inside. In order to effectively prevent the electrolyte from accumulating in the storage chamber (88), the connecting plate (86) is inclined along the longitudinal direction of the dry battery (9) and discharged from one through hole (87). Also good.
