Further, the right side surface of the housing 1 includes a memory card slot (not shown) in which a memory card as a recording medium can be attached and detached, and a first cover member 6 in which the memory card slot can be opened and closed. Further, as shown in FIG. 1B, the back surface of the housing 1 includes a battery storage unit that can store a battery, an opening / closing lid 4 that seals the battery storage unit, a stand member 5, and an antenna 8. The left side surface of the housing 1 includes an input / output terminal (not shown) and a second cover member 7 that can open and close the input / output terminal. The present embodiment is characterized by the structure of the battery housing part and the opening / closing lid 4.

  FIG. 2 is an exploded perspective view showing the configuration of the battery attaching / detaching structure. As shown in FIG. 2, the housing 1 is provided with a concave battery storage recess 11 in which the battery 20 can be stored. The battery housing recess 11 is surrounded by a resin wall 12 and has an upper surface 11a, a lower surface 11b, a left side surface 11c, a right side surface 11d, and a bottom surface 11e. A support member 13 made of an elastic resin such as silicon is disposed on the outer peripheral portion of the wall portion 12. An electrical contact 15 is disposed on the lower surface 11 b of the battery housing recess 11. A leaf spring 16 is disposed on the upper surface 11 a of the battery housing recess 11. A rib 17 is formed in a portion of the battery housing recess 11 that faces the bottom surface 11 e in the vicinity of the electrical contact 15. Further, a recess 18 is formed outside the battery housing recess 11 on the back surface of the housing 1.

  The support member 13 is disposed so as to surround the wall portion 13. Further, the support member 13 has a groove 13 a formed on the same surface as the back surface of the housing 1. The outer peripheral portion of the wall portion 12 is surrounded by a part of the housing 1. Therefore, the support member 13 is sandwiched between the wall portion 12 and the housing 1. In addition, two holes 14 are formed between the support member 13 and the upper surface of the housing 1 on the rear surface of the housing 1.

  The hole portion 14 has a size with which a claw portion 44 (described later) formed in the opening / closing lid 4 can be engaged.

  The electrical contact 15 is connected to a power circuit arranged in the housing 1. Further, the electrical contact 15 is partly exposed at the lower surface 11 b and the exposed portion of the electrical contact 15 contacts the electrode 21 of the battery 20 when the battery 20 is mounted in the battery housing recess 11.

  The leaf spring 16 can urge the battery 20 mounted in the battery housing recess 11 toward the lower surface 11b. Further, the leaf spring 16 has a slight gap between it and the upper surface 11a. In addition, the leaf spring 16 has a slight gap with respect to the upper surface 20a of the battery 20 or the upper surface 20a and the leaf spring 16 so that the leaf spring 16 is not elastically deformed when the opening / closing lid 4 is not attached. Is touching. Therefore, the battery 20 is not biased toward the lower surface 11b.

  The ribs 17 prevent damage and deformation of the electrical contacts 15 due to erroneous insertion of the battery 20. That is, when the battery 20 is moved in the normal direction of the bottom surface 11 e and inserted into the battery housing recess 11, the end of the battery 20 comes into contact with the upper surface of the electrical contact 15, and the electrical contact 15 is damaged or deformed. There is a possibility that. Since the ribs 17 are provided as in the present embodiment, the battery 20 must be inserted in an oblique direction with respect to the bottom surface 11e, so that the end of the battery 20 comes into contact with the upper surface of the electrical contact 15. It is possible to prevent the electrical contact 15 from being damaged or deformed.

  The recess 18 is formed at a position in contact with the end of the opening / closing lid 4 in a state where the battery housing recess 11 is sealed, and when the user removes the opening / closing lid 4, a finger or a nail is hooked on the end of the opening / closing lid 4. This is to make it easier.

  The battery 20 is a secondary battery having a substantially rectangular parallelepiped shape. In addition, the lower surface 20b of the battery 20 is provided with a terminal 21 that can supply power to the portable television by being electrically connected to the electrical contact 15 disposed in the battery housing recess 11 of the portable television. The shape of the battery 20 is an example. The battery 20 is not limited to a secondary battery but may be a primary battery. In the case of a primary battery, if the electrical contact 15 is a positive contact and the leaf spring 16 is a negative contact, the same as in the present embodiment. To work.

  FIG. 3 is a perspective view showing the configuration of the opening / closing lid 4. The opening / closing lid 4 has a wall portion 42 and a protrusion 43 formed on the back surface of a substantially plate-like lid portion 41 having a size capable of covering the battery housing recess 11. The opening / closing lid 4 has two claw portions 44 formed on one side surface.

  The wall portion 42 is formed in a substantially square shape so that it can be fitted into the groove portion 13 a of the support member 13. Moreover, the wall part 42 has a thickness larger than the groove width of the groove part 13a, and it fits it, expanding the groove part 13a.

  The protrusion 43 is inserted between the leaf spring 16 and the upper surface 11a of the battery housing recess 11 in a state where the battery housing recess 11 is covered with the opening / closing lid 4, and presses the leaf spring 16 toward the lower surface 11b. Therefore, the thickness of the protrusion 43 is larger than the gap between the leaf spring 16 and the upper surface 11a of the battery housing recess 11. In addition, the protrusion 43 has an inclined surface 43a and has a thin tip. The inclined surface 43 a is for facilitating insertion of the protrusion 43 between the leaf spring 16 and the upper surface 11 a of the battery housing recess 11 when the opening / closing lid 4 is mounted on the housing 1.

  Next, the mounting operation of the battery 20 and the opening / closing lid 4 will be described.

  FIG. 4 is a plan view of the battery housing recess 11 and the vicinity thereof in a state where the battery 20 and the opening / closing lid 4 are not mounted. FIG. 5 is a cross-sectional view taken along the line ZZ in FIG. When the battery 20 is mounted in the battery housing recess 11 in the state shown in FIGS. 4 and 5, the lower surface 20 b side of the battery 20 is placed between the rib 17 and the bottom surface 11 e of the battery housing recess 11 as shown by an arrow A. Then, as shown by arrow B, the entire battery 20 is inserted into the battery housing recess 11. FIG. 6 (sectional view) shows a state where the battery 20 is inserted into the battery housing recess 11.

  As shown in FIG. 6, in the state where the battery 20 is mounted in the battery housing recess 11, the upper surface 11a, the lower surface 11b, the left surface 11c, and the right surface 11d of the battery housing recess 11 are roughly approximated in the horizontal direction of the battery 20. Positioning has been made. Further, the electrode 21 is in a position where it can contact the electrical contact 15 (position facing the electrical contact 15), but there is a gap between the leaf spring 16 and the battery 20, or the leaf spring 16 is not elastically deformed. Since the leaf spring 16 and the battery 20 are in contact with each other (the leaf spring 16 is in a low spring pressure state) and the urging force of the leaf spring 16 does not act on the battery 20, the electrode 21 and the electrical contact 15 are There is no reliable electrical connection.

  Next, the battery housing recess 11 is sealed with the opening / closing lid 4. In order to mount the opening / closing lid 4, first, the claw portion 44 formed in the opening / closing lid 4 is inserted into the hole portion 14, and then the wall portion 42 is inserted into the groove portion 13 a of the support member 13. FIG. 7 (sectional view) shows a state in which the battery housing recess 11 is sealed with the opening / closing lid 4.

  As shown in FIG. 7, the opening / closing lid 4 is inserted into the groove 13 a while the wall 42 pushes and widens the groove 13 a in a state where the battery housing recess 11 is sealed. Therefore, since the wall part 42 is clamped by the elastic return force of the support member 13, the support member 13 can hold | maintain the opening-and-closing lid 4 by this. Further, since the claw portion 44 is engaged with the hole portion 14, it is possible to prevent the opening / closing lid 4 from being detached.

  Further, the protrusion 43 is inserted between the leaf spring 16 and the upper surface 11a. Since the gap between the leaf spring 16 and the upper surface 11a is smaller than the thickness of the protrusion 43, when the protrusion 43 is inserted, the leaf spring 16 is pushed toward the upper surface 20a of the battery 20 (the direction indicated by arrow C). It is elastically deformed and the spring pressure of the leaf spring 16 is increased. The elastically deformed leaf spring 16 urges the battery 20 toward the lower surface 11b as indicated by an arrow C. As a result, the electrode 21 is pressed against the electrical contact 15 and the two are reliably electrically connected. Further, the battery 20 is firmly positioned.

  Next, the detachment operation of the battery 20 and the opening / closing lid 4 will be described.

  As shown in FIG. 7, in a state where the opening / closing lid 4 is held by the support member 13, a recess 18 is formed in a portion of the rear surface of the housing 1 that contacts the opening / closing lid 4, and a finger is placed on the side surface of the opening / closing lid 4. It is configured so that it can be applied. With the finger placed on the side surface of the opening / closing lid 4 through the recess 18, the opening / closing lid 4 is lifted in the direction shown by the arrow D, so that the opening / closing lid 4 pivots the engaging portion between the claw portion 44 and the hole portion 14. And the wall 42 is detached from the groove 13a. Next, the opening / closing lid 4 is detached from the housing 1 by removing the claw portion 44 from the hole portion 14.

  As shown in FIG. 6, the projection 43 is detached from the gap between the leaf spring 16 and the upper surface 11a by detaching the opening / closing lid 4 from the housing 1, so that the bias of the leaf spring 16 against the battery 20 is released. The Thereby, the spring pressure of the leaf | plate spring 16 falls and the positioning of the battery 20 becomes loose. In this state, when the user inserts a finger or a nail into the gap between the upper surface 20a of the battery 20 and the upper surface 11a of the battery housing recess 11 and lifts the battery 20 in the removing direction indicated by the arrow E, the battery 20 As shown by the arrow F, the portion held by the rib 17 is rotated about the axis. By rotating the upper surface 20a to a position where the upper surface 20a is detached from the battery housing recess 11, the engagement between the end portion on the lower surface 20b side of the battery 20 and the rib 17 can be released. Thereby, the battery 20 can be detached from the battery housing recess 11.

  According to the present embodiment, as shown in FIG. 6, when only the battery 20 is mounted in the battery housing recess 11, the battery 20 is positioned in the battery housing recess 11 without being fixed in position. The battery 20 can be easily detached from the battery housing recess 11 without requiring a large force. That is, the user only needs to remove the opening / closing lid 4 from the housing 1 in order to make the battery 20 easily detachable.

  Further, as shown in FIG. 7, when the opening / closing lid 4 is mounted at a position where the battery housing recess 11 is sealed with the battery 20 inserted into the battery housing recess 11, the protrusion 43 presses the leaf spring 16. Since the leaf spring 16 is configured to press the battery 20 toward the electrical contact 15, the position of the battery 20 can be fixed and the electrode 21 can be pressed against the electrical contact 15. It can be securely connected. Further, since the spring pressure of the leaf spring 16 can be increased, the battery 20 can be firmly positioned in the battery housing recess 11. That is, the user only needs to attach the opening / closing lid 4 to a position that covers the battery housing recess 11 in order to achieve reliable electrical connection of the battery 20 to the portable device and firm positioning of the battery 20. .

  Moreover, in this Embodiment, the complicated operation (operation which arrange | positions a string to the lower part of a battery) as disclosed by patent document 1 is unnecessary, and the attachment or detachment operativity of the battery 20 can be improved.

  Note that although a portable television receiver is described as an example of a portable device in this embodiment, the portable device is driven by a battery that can be attached to and detached from at least the device, such as a cellular phone terminal, a portable game machine, and a portable medical device. The present embodiment is effective for any device.

  The leaf spring 16 in the present embodiment is an example of an urging member in the present invention. Moreover, the protrusion part 43 in this Embodiment is an example of the press part in this invention.

  The present invention is useful for a portable device to which a battery can be attached and detached.
