In particular, if liquid infiltrates through the joint between the recess 63 of the cover 60 and the cover portion 52, the liquid may adhere to the connection terminal 19 and deteriorate the connection terminal 19.

In particular, if there is a portion where the cover 60 and the cover portion 52 overlap in the depth direction (Y direction) of the recess 18, such a portion forms a liquid infiltration path, and the liquid adheres to the connection terminal 19. It will be easier. However, such an overlapping portion is a portion necessary for restricting the lifting of the cover 60 in the −Y direction when the cover 60 is attached to the battery mounting portion 50.

Specifically, in the present embodiment, such a portion corresponds to the convex portion 61 and the protrusion 62 described with reference to FIG. 9, but in the present embodiment, the convex portion 61 and the protrusion 62 are the edges of the covering portion 52. When the liquid infiltrates from the portion where the portion 52a and the edge portion 63a of the recess 63 face each other, the liquid is located outside the path toward the connection terminal 19 (indicated by reference numeral S in FIGS. 13 and 14). .. Therefore, even if the liquid infiltrates from the portion where the edge portion 63a of the cover 60 and the edge portion 52a of the cover portion 52 face each other, it is possible to prevent the liquid from advancing straight toward the connection terminal 19.

In the present embodiment, as shown in FIGS. 13 and 14, the cover portion 52 extends in the extending direction (+ X direction) of the connection terminal 19 from the tip end portion of the connection terminal 19, so that the cover 60 When a liquid infiltrates from a portion where the edge portion 63a of the cover portion 52 and the edge portion 52a of the cover portion 52 face each other, it is possible to suppress the arrival of the liquid at the connection terminal 19.

Further, in the present embodiment, as shown in FIG. 9, the recess 64 as the notch portion, that is, the recess 64 for forming the opening for inserting the finger is removed from the portion facing the cover portion 52 at the peripheral edge of the cover 60. Since it is formed at the position, even if the liquid enters from the recess 64, it is possible to prevent the liquid from reaching the connection terminal 19.

Subsequently, another embodiment will be described with reference to FIG. The cover 60A shown in FIG. 15 has an overlapping portion 67 that overlaps with the covering portion 52A in the Y direction, and the overlapping portion 67 effectively suppresses the floating of the cover 60A in the −Y direction.
The overlapping portion 67 facilitates the formation of a liquid infiltration path, but the liquid that has entered through the gap between the covering portion 52A and the cover 60A, that is, the portion of the covering portion 52A facing the overlapping portion 67, enters the connection terminal 19. Grooves 69 extending in the Z-axis direction are formed in the direction of the path at appropriate intervals in the X-axis direction. The length of the groove portion 69 in the Z-axis direction can be made the same as, for example, the length of the covering portion 52A in the Z-axis direction. Therefore, when the liquid enters the plurality of groove portions 69, it is possible to prevent the liquid from advancing straight toward the connection terminal 19.

Subsequently, another embodiment will be described with reference to FIG. The cover 60A shown in FIG. 15 has an overlapping portion 67 that overlaps with the covering portion 52B in the Y direction, and the overlapping portion 67 effectively suppresses the floating of the cover 60A in the −Y direction.
The overlapping portion 67 facilitates the formation of a liquid infiltration path, but the liquid that has entered through the gap between the covering portion 52B and the cover 60A, that is, the portion of the covering portion 52B facing the overlapping portion 67, enters the connection terminal 19. A liquid absorbent 70 is provided on the path to the route. The length of the liquid absorbent 70 in the Z-axis direction can be made the same as, for example, the length of the covering portion 52B in the Z-axis direction. Therefore, the liquid absorbent 70 can prevent the liquid from advancing straight toward the connection terminal 19.

Subsequently, another embodiment will be described with reference to FIG. The cover 60B shown in FIG. 17 has an overlapping portion 68 that overlaps with the covering portion 52 in the Y direction, and the overlapping portion 68 effectively suppresses the floating of the cover 60B in the −Y direction. The overlapping portion 68 is formed so as to overlap the covering portion 52 on both sides in the Z-axis direction.
The overlapping portion 68 is provided at a position where the liquid deviates from the path S toward the connection terminal 19, so that the liquid enters from a portion where the edge portion 63a of the cover 60B and the edge portion 52a of the cover portion 52 face each other. Even so, it is possible to prevent the liquid from advancing straight toward the connection terminal 19.

Next, an angle regulating unit that regulates the angle formed by the connection terminal 19 (see FIG. 6) included in the battery mounting portion and the charging terminal 30 (see FIG. 7) provided in the second battery will be described.
FIG. 18 shows a cross section in a configuration without an angle regulating unit, and first, a technical problem in a configuration without an angle regulating unit will be described below.
As described above, in the second battery 20, a charging terminal 30 connected to the connection terminal 19 provided in the housing 2 is provided at the end in the −X direction. Then, when mounting the second battery 20, the end portion of the second battery 20 in the −X direction is fitted into the recess 18. The portion of the second battery 20 into which the recess 18 enters is indicated by reference numeral 20d, and hereinafter, this portion is referred to as a convex portion 20d (see also FIG. 7). Reference numeral 20c is a side surface of the second battery 20 in the −X direction.

When the convex portion 20d of the second battery 20 is fitted into the concave portion 18, if the posture of the second battery 20 is tilted in the XY plane as shown in FIG. 18, the connection terminal 19 and the charging terminal 30 are parallel to each other. That is, the angle α becomes large. If the second battery 20 is slid in the −X direction in this state, the charging terminal 30 may be disconnected from the connection terminal 19 and may not be properly connected. In addition, there is a risk of damaging the substrate fixing each terminal.
In addition, when the corner portion 20e in the + X direction of the convex portion 20d comes into contact with the edge portion 18a in the + X direction of the concave portion 18, the connection terminal 19 and the charging terminal 30 cannot face each other and cannot be properly connected.

Therefore, the second battery 20A shown in FIGS. 19 and 19 is provided with angle regulating units 71A and 71B that regulate the angle formed by the connection terminal 19 and the charging terminal 30.
As shown in FIGS. 19 and 20, the angle regulating portion 71A is composed of a protruding portion 72 protruding in the −X direction on the side surface 20c. In this embodiment, two protrusions 72 are provided at intervals in the Z-axis direction.
As shown in FIG. 20, the protrusion 72 of the second battery 20A when the connection terminal 19 and the charging terminal 30 are connected by contacting the outer surface of the housing 2 when the second battery 20A is mounted. The inclination is regulated, and the angle formed by the connection terminal 19 and the charging terminal 30 is regulated. As a result, the connection terminal 19 and the charging terminal 30 can be appropriately connected.
In the present embodiment, two protrusions 72 are arranged at intervals in the Z-axis direction, but the present invention is not limited to this, and one or three or more protrusions 72 may be provided or extend along the Z-axis direction. It may be formed in. Further, the larger the protrusion amount of the protrusion 72 in the −X direction, the greater the effect of suppressing the inclination of the second battery 20A, but in consideration of the easiness of damage of the protrusion 72 and the suppression of the increase in size of the battery body. It is preferable to consider the amount of protrusion of the protrusion 72.

Next, as shown in FIGS. 19, 22, and 23, the angle regulating portion 71B is composed of a protruding portion 73 that protrudes in the + X direction and is provided on the opposite side of the convex portion 25 described above in the X-axis direction. To. As shown in FIG. 23, the protrusion 73 abuts on the contact surface 53 extending in the X-axis direction, that is, in the slide direction of the second battery 20A, thereby forming the connection terminal 19 and the charging terminal 30. Suppresses the inclination of the second battery 20A in the XZ plane when the batteries are connected. As a result, the connection terminal 19 and the charging terminal 30 can be appropriately connected.

Further, in the second battery 20A, the corner portion of the convex portion 20d in the + X direction is chamfered to form the chamfered portion 20f. With this chamfered portion 20f, when the convex portion 20d of the second battery 20A is fitted into the concave portion 18 as shown in FIG. 21, the connection terminal is formed with a gap between the connection terminal 19 and the charging terminal 30. The 19 and the charging terminal 30 can face each other, that is, the angle α shown in FIG. 18 is 0 ° or close to it. As a result, the connection terminal 19 and the charging terminal 30 can be appropriately connected.

The above configuration is not limited to a recording device represented by a printer, and can be adopted for other electronic devices, for example, an image reading device represented by a scanner, and other electronic devices provided with an external battery.

Further, the present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the invention described in the claims, and these are also included in the scope of the present invention. Needless to say, there is.
