Description

  The present invention relates to an electronic apparatus including a battery lid unit that covers an opening of a storage unit that stores a battery.

  2. Description of the Related Art Conventionally, small and light electronic devices generally have a structure in which a battery used as a power source is stored inside the device and the battery is covered with a lid. Moreover, as a usage form of the battery in an electronic device, there are many examples in which a plurality of small cylindrical batteries such as AA batteries are used. Various techniques have been proposed for battery storage of digital cameras (hereinafter referred to as cameras), which are electronic devices (see, for example, Patent Document 1).

  22A and 22B are views showing the appearance of the camera according to the first conventional example (Patent Document 1), where FIG. 22A is a perspective view of the camera 101, and FIG. 22B is a battery lid 107 on the bottom side of the camera 101. FIG. 3 is a perspective view showing a state in which a plurality of batteries 103 to 106 are stored in the storage unit 102. FIG.

  22 (a) and 22 (b), the batteries 103 to 106 are designated in the insertion direction into the storage unit 102, respectively. The batteries 103 and 105 are inserted into the housing portion 102 from the positive electrode side, and the batteries 104 and 106 are inserted from the negative electrode side, and the battery cover 107 is closed. 24, the negative terminal 108a of the terminal plate 108 provided on the battery lid 107 is in contact with the negative electrode 103b of the battery 103, and the positive terminal 108b is in contact with the negative electrode 104a of the battery 104. Further, the negative terminal 109 a of the terminal plate 109 is in contact with the negative electrode 105 b of the battery 105, and the positive terminal 109 b is in contact with the positive electrode 106 a of the battery 106.

  Further, the positive terminal 110 a of the terminal plate 110 provided in the housing portion 102 is in contact with the positive electrode 103 a of the battery 103, and the negative terminal 111 a of the terminal plate 111 is in contact with the negative electrode 104 b of the battery 104. Further, the positive terminal 111 b of the terminal plate 111 is in contact with the positive electrode 105 a of the battery 105, and the negative terminal 112 a of the terminal plate 112 is in contact with the negative electrode 106 b of the battery 106. In this case, each of the terminal plates 108 to 112 has a spring performance and is in contact with the electrode of each battery with a predetermined contact pressure. Thereby, the voltage for four series batteries is obtained between the terminal board 110 and the terminal board 112, and a voltage can be taken in as a drive power supply of the camera 101 inside.

  Here, the necessity of the spring performance of each of the terminal plates 108 to 112 will be described. One object is to contact the electrodes of each battery with a predetermined contact pressure to ensure energization as described above. . Another object is that when a strong vibration shock is applied during operation of the camera and each battery in the storage part swings, the contact part of each battery electrode is momentarily separated and insulated. One example is to prevent the supply from being cut off. If the camera is shut off, for example, the moving image being shot may be interrupted, the still image being recorded in the internal memory may disappear, or the electronic circuit itself may be damaged.

  Therefore, the spring performance of each of the terminal plates 108 to 112 is not limited to ensuring conductivity with the electrode of each battery in a normal use state, and each battery follows the battery even if it swings due to vibration shock. The important purpose is to maintain contact with the electrodes and maintain the energized state.

  For example, when the batteries 103 to 106 are moved downward by vibration shock in the state of FIG. 24, the terminal plates 110 to 112 bend until the tips contact the terminal holding portion 113. At the same time, the terminal plates 108 and 109 of the battery lid 107 follow the direction of the batteries 103 to 106 and maintain the contact state. Even if the batteries 103 to 106 return upward due to the reaction of the impact, the contact state can be maintained by the spring force of the terminal plates 110 to 112. As a result, the battery continues to maintain contact even when an impact is applied during the operation of the camera.

  As another problem, since the battery has a cylindrical shape, it may occur that the battery is inserted in a direction opposite to a predetermined insertion direction with respect to the storage portion of the camera. If the battery is inserted incorrectly or deliberately, not only the desired voltage can be obtained, but the reversely inserted battery can be energized in the opposite direction to the correct discharge current, resulting in battery heat generation and leakage. May cause damage or damage to electronic circuits.

  Therefore, in order to prevent reverse insertion of the battery, there is a contact prevention mechanism at the time of reverse insertion using the circular convex shape of the positive electrode of the battery (mechanism for preventing contact between the electrode on the reverse insertion side of the battery and the terminal on the camera side). Often provided. A technique has been proposed in which a contact prevention mechanism for reverse insertion of a battery is provided inside the battery compartment of the camera (see, for example, Patent Document 2).

  FIG. 25 is an exploded perspective view of the terminal spring 201 and the insulating member 202 on the battery chamber side of the camera according to the second conventional example (Patent Document 2).

  In FIG. 25, an insulating member 202 is attached to a coil spring-like terminal spring 201 to prevent contact during reverse insertion of the battery as follows. When the positive electrode 203a of the battery 203 is correctly attached as shown by the solid line in FIG. 26, the positive electrode 203a contacts the terminal spring 201. On the other hand, as shown by a broken line in FIG. 26, when the negative electrode 203b of the battery 203 is erroneously attached, the negative electrode 203b does not contact the terminal spring 201 because it is blocked by the insulating member 202.

  However, regarding the terminals provided on the battery lid side, it is important to consider that the user can easily touch the terminals. Therefore, in Patent Document 1 shown in FIG. 23, the arm portions of the spring portions 108c and 108d of the terminal plate 108 and the spring portions 109c and 109d of the terminal plate 109 which are provided on the battery lid 107 are prevented from being deformed by external pressure. It is formed by a short and wide leaf spring. Further, insulating members 114 to 117 are provided there.

  With this structure, as shown in FIG. 27, the batteries 103 and 104 can be energized when the batteries 103 and 104 are correctly inserted into the storage unit 102. However, when the batteries 103 and 104 are reversely inserted as shown in FIG. The insulation members 114 and 115 are disconnected from each other and cannot be energized. Further, when a vibration shock is applied to the camera as described above, the contact conductivity is maintained by following the swinging of the batteries 103 to 106 by the spring property provided in the spring portions 108c, 108d, 109c, and 109d (FIG. 23). I am letting.

  As another method of battery terminals provided on the battery lid side, a technique as shown in FIG. 29 in which a fixed insulating member is provided has been proposed.

  FIG. 29 is a perspective view showing an appearance of a camera 301 according to the third conventional example. FIG. 30 is an exploded perspective view of the battery cover 302 of the camera 301.

  In FIG. 29, insulating portions 303a and 303b are projected from an inner cover 303 provided on the battery cover 302 of the camera 301. As a result, when the battery 304 is correctly inserted, the contact portion 306a of the terminal plate 306 contacts the positive electrode 304a of the battery 304, so that energization is possible. When the battery 304 is reversely inserted, since the negative electrode 304b (not shown) of the battery 304 hits the insulating portions 303a and 303b of the inner cover 303, the contact portion 306a of the terminal plate 306 is not in contact with the negative electrode 304b of the battery 304. Impossible.

When a vibration shock is applied to the camera, the spring property provided on the spring portion 306b of the terminal plate 306 follows the swinging of the battery 304 and maintains the conductivity associated with the contact. As shown in FIG. 30, the contact portion 306 a of the terminal plate 306 has a so-called cantilever spring type structure. A claw portion 306 c is provided at the tip, and the contact portion 303 a is hooked on the hole 303 c of the inner cover 303. The amount of protrusion is regulated. With this method, the contact portion 306a can be precharged to have an initial load as compared with Patent Document 1, so that a stronger contact load can be obtained and contact conductivity can be easily maintained.
Japanese Patent Laying-Open No. 2004-253263 (FIGS. 1, 3, 4, 5, and 6) Japanese Patent No. 2624350 (FIGS. 1 and 3)

  In the second conventional example (Patent Document 2), there is no problem with the structure in which the terminal is disposed in the back of the battery housing portion of the camera, but in the structure in which the terminal is disposed on the battery lid side, the terminal is exposed when the battery lid is opened. It becomes. Therefore, there is a problem that a user may touch the terminal directly with his / her hand to cause an unexpected injury, or the terminal may collide with the battery and deform the protruding portion of the terminal tip.

  Further, in the first conventional example (Patent Document 1), it is important to manage the protruding amount of the terminal, such as restraining the protruding height so that the terminal cannot be easily turned up by hand, and the management is complicated.

  The third conventional example has a locking mechanism for preventing protrusion, so that the terminal cannot be easily turned up by hand, but the tip of the terminal is movable while the insulating member is fixed. Therefore, if the protruding amount of the terminal exceeds the height of the insulating member, the terminal comes into contact with the negative electrode of the reversely inserted battery, so that the management of the protruding amount of the terminal is important and management is complicated. The projecting amount is a combination of the dimensions of each member constituting the battery lid unit, such as the dimensions of the inner cover 303 attached to the battery lid 302, the heights of the insulating portions 303a and 303b, and the shapes of the claw portions 306c of the terminal plate 306. And get involved. Therefore, there is a problem that it is difficult to manage the dimension of the protrusion amount.

  When assembling the battery lid unit, the slide plate 307, the lever member 308, and the springs 309 and 310 are assembled and pressed while the claw portion 306c of the terminal plate 306 is hooked in the hole 303c of the inner cover 303, and finally the screw. 311 must be tightened. Therefore, there is a problem that the assemblability is not good.

  In view of the above, there is a demand for a battery terminal that can be assembled by a simpler method and that can maintain the insulation when managing the protruding amount and when the battery is inserted backward.

  SUMMARY OF THE INVENTION An object of the present invention is to provide an electronic device that facilitates assembly work and facilitates management of the protruding amount and protruding pressure of a terminal that contacts a battery.

  In order to achieve the above-described object, the present invention provides an electronic device having a battery housing portion, a fixing portion for fixing to the electronic device, a displacement portion with respect to the fixing portion, and the battery A terminal plate formed with a contact portion that contacts the positive electrode of the battery housed in the housing portion, and a reverse that is attached to the contact portion of the terminal plate and functions so that the negative electrode of the battery does not contact the contact portion. And an insulating member on which a connection preventing rib is formed, and the displacement amount of the contact portion is regulated by engaging the insulating member and the fixing portion of the terminal plate.

FIG. 10 is a perspective view showing a state in which the claw portion of the stopper member 13 hits the fixed portion of the terminal board 9.

  In FIG. 4, the terminal plate 9 is attached to the inside of the outer cover 8, and is in contact with the negative electrode 4 b of the battery 4 and the positive electrode 5 a of the battery 5 stored in the battery storage unit 3, so that power is supplied from the battery. It is formed of a conductive leaf spring material. The terminal plate 9 includes a fixed portion 9a fixed to the outer cover 8, an extending portion 9b, a folded portion 9c, a contact portion 9d, sharp protrusions 9e and 9f, a long hole portion 9g, an extending portion 9h, a root portion 9i, A contact portion 9j, sharp protrusions 9k and 9l, a throttle portion 9m, and a claw portion 9n are provided.

  A contact portion 9 d is provided as a terminal that contacts the battery 5 on the terminal plate 9. That is, the extended portion 9b extending in a band shape from the bent portion 9p is folded in the direction of the fixed portion 9a at the folded portion 9c provided near the middle (middle portion), and near the tip of the battery 5 A contact portion 9d that contacts the positive electrode 5a is provided. The contact portion 9d swings around the turning portion 9c as the swing center. Therefore, the contact portion 9d can be displaced with respect to the fixed portion 9a.

  The sharp protrusions 9e and 9f (protrusions) of the terminal plate 9 are drilled into a leaf spring material to be the contact portion 9d as shown in FIG. 5, and then squeezed into a conical shape as shown in FIG. Thus, a sharp ridge line edge is formed. The sharp protrusions 9e and 9f of the terminal board 9 actually come into contact with the positive electrode 5a of the battery 5. Here, when the outer cover 8 is slid through the slide plate 14, the sharp protrusions 9 e and 9 f of the terminal plate 9 are configured to slide on the surface of the positive electrode 5 a of the battery 5.

  The fixed portion 9a of the terminal board 9 is formed with a bent portion 9p bent in the displacement direction of the contact portion 9d. And the long hole part 9g is provided in the bending part 9p center. The long hole portion 9g of the terminal plate 9 extends in parallel with the direction in which the contact portion 9d protrudes.

  A contact portion 9 j is provided as a terminal that contacts the battery 4 on the terminal plate 9. That is, the fixed portion 9a is formed with a bent portion 9i bent in the displacement direction of the contact portion 9j. And the extension part 9h is extended in the strip | belt shape from the bending part 9i. The extending portion 9h swings with respect to the bent portion 9i, and a contact portion 9j is provided at the tip of the extending portion 9h. Accordingly, the contact portion 9j is configured to protrude toward the battery 4 and be urged.

  The sharp protrusions 9k and 9l of the terminal board 9 are formed with ridge line edges in the same manner as the sharp protrusions 9e and 9f. The sharp protrusions 9k and 9l of the terminal plate 9 actually come into contact with the negative electrode 4b of the battery 4. The drawn portion 9m of the terminal board 9 is obtained by drawing the edge so as not to be injured even if the user touches the edge of the contact portion 9j with his / her hand. The claw part 9n of the terminal board 9 is for suppressing the protrusion amount of the contact part 9j to an amount smaller than that in the no-load state, and precharging (preloading) the contact part 9j. The claw 9n of the terminal board 9 will be described later.

  The stopper member 13 is formed of an insulating material, and a pair of claw portions 13a that engage with the elongated holes 9g of the terminal plate 9 and a pair that is set a predetermined amount wider than the width of the protrusion of the positive electrode 5a of the battery 5. Rib portions 13b and 13c. The pair of rib portions 13 b and 13 c (reverse connection preventing ribs) of the stopper member 13 is configured to sandwich the protrusion of the positive electrode 5 a of the battery 5 stored in the battery storage portion 3.

  In addition, the pair of rib portions 13b and 13c of the stopper member 13 allows the positive electrode 5a of the battery 5 to be in a state where the battery 5 is correctly stored in the battery storage portion 3 and the contact portion 9d of the terminal plate 9 is in contact with the positive electrode 5a of the battery 5. The height is set so as not to prevent contact with the contact portion 9d of the terminal board 9. On the other hand, when the battery 5 is inserted into the battery housing part 3 in the reverse direction, the height is set so as to prevent the negative electrode 5 b of the battery 5 from coming into contact with the contact part 9 d of the terminal plate 9. That is, it functions so that the negative electrode of the battery does not come into contact with the contact portion 9d.

  The stopper member 13 is attached to the contact portion 9d as shown in FIG. 7 by being inserted into the contact portion 9d of the terminal plate 9 from the illustrated arrow direction (tip direction) when the terminal plate 9 is not fixed to the outer cover 8. . Thereby, as shown in FIG. 8, a step L is obtained between the tips of the sharp protrusions 9 e and 9 f provided on the contact portion 9 d of the terminal plate 9 and the rib portion 13 b of the stopper member 13.

  While the terminal plate 9 and the stopper member 13 are in the state of FIG. 8, as shown in FIG. 9, while the extension portion 9b of the terminal plate 9 is bent downward (the direction opposite to the direction in which the contact portion 9d protrudes), The claw portion 13 a of the stopper member 13 is engaged with the long hole portion 9 g of the terminal board 9. After the claw portion 13 a of the stopper member 13 is engaged with the elongated hole portion 9 g of the terminal plate 9, the terminal plate 9 is fixed to the outer cover 8. In this case, the protruding amount of the contact portion 9 d of the terminal plate 9 is suppressed within a range in which the claw portion 13 a of the stopper member 13 can move in the long hole portion 9 g of the terminal plate 9. Therefore, the displacement amount of the contact portion 9d is regulated by the engagement between the claw portion 13a and the long hole portion 9g.

  As shown in FIG. 10, since the claw portion 13a of the stopper member 13 hits the fixing portion 9a of the terminal plate 9, the protruding amount of the contact portion 9d bent by the folded portion 9c of the terminal plate 9 is smaller than that in the no-load state. To be in a precharged state. Since the protruding amount and the precharge force of the contact portion 9d of the terminal plate 9 are determined only by the terminal plate 9 and the stopper member 13, it is easy to manage the protruding amount and the protruding pressure of the contact portion 9d. Also, assembly is easy.

  Next, the configuration of the lid unit 2 and the assembly procedure of the lid unit 2 in the camera of the present embodiment will be described with reference to FIGS.

  FIG. 11 is an exploded perspective view of the lid unit 2. FIG. 12 is a plan view showing an operating state of the lock lever of the lid unit 2. FIG. 13 is a plan view showing the operating state of the lock lever of the lid unit 2. FIG. 14 is a plan view showing the operating state of the lock lever of the lid unit 2. FIG. 15 is a cross-sectional view showing a state in which the claw portion of the terminal plate hits the inner cover of the lid unit 2.

  In FIG. 11, the lid unit 2 includes an outer cover 8, a slide plate 14, an inner cover 15, a lock lever 16, and a lever spring 17. The lid unit 2 is configured such that a slide plate 14 formed of a stainless steel plate is slidably movable (slidable) inside an outer cover 8 formed of a mold material, and the inner cover 15 is covered on the slide plate 14. It has a structure that restricts the sliding movement between the closed position and the open position.

  The outer cover 8 includes a sliding surface 8c, a hole 8d, and guide grooves 8e and 8f. The slide plate 14 includes a stopper portion 14a, a plate hole 14b, and a bearing portion 14c. The inner cover 15 includes a dowel portion 15a and a hole portion 15b. The lock lever 16 includes an operation portion 16a, a hook portion 16b, a switch tact portion 16c, and a spring attachment portion 16d.

  The slide plate 14 is mounted (coupled) on the inner side of the outer cover 8, can slide with respect to the outer cover 8, and rotates via the bearing portion 14 c with respect to the camera body 1 (base) to which the lid unit 2 is attached. Is configured to be possible. In this case, the sliding direction of the slide plate 14 and the extending direction of the rib portions 13b and 13c of the stopper member 13 are set to coincide with each other.

  The lock lever 16 is disposed on a sliding surface 8c provided on the inner side of the outer cover 8, and is configured to operate an operation portion 16a protruding outward from the hole 8d of the outer cover 8. The hook portion 16b and the switch tact portion 16c operate together in accordance with the operation of the operation portion 16a of the lock lever 16. The lever spring 17 is attached to the spring attachment portion 16d of the lock lever 16 and constantly urges the lock lever 16. The lock lever 16 and the lever spring 17 are attached to the outer cover 8, and the slide plate 14 is inserted into the guide grooves 8 e and 8 f of the outer cover 8.

  In the state shown in FIG. 12, the stopper portion 14 a of the slide plate 14 abuts against the hook portion 16 b of the lock lever 16 and restricts the movement of the lock lever 16, so that the lock lever 16 does not move even when pressed by the lever spring 17. . As shown in FIG. 13 from the state shown in FIG. 12, when the slide plate 14 is inserted all the way (to the lock lever 16 side), the stopper portion 14 a of the slide plate 14 is detached from the hook portion 16 b of the lock lever 16.

  Accordingly, the lock lever 16 is moved by the urging of the lever spring 17 to change from the state shown in FIG. 13 to the state shown in FIG. 14, and the hook portion 16b of the lock lever 16 is engaged with the stopper portion 14a of the slide plate 14. As a result, the slide plate 14 does not move. When the inner cover 15 (FIG. 11) is put on the slide plate 14 in the state shown in FIG. 14, the dowel portion 15 a of the inner cover 15 engages with the plate hole 14 b of the slide plate 14. As a result, the slide plate 14 can move with respect to the outer cover 8 within the engagement range of the dowel portion 15a of the inner cover 15 and the plate hole 14b of the slide plate 14.

  Further, the terminal plate 9 is attached with the inner cover 15 covered on the slide plate 14, and the claw portion 9 n provided at the tip of the contact portion 9 j of the terminal plate 9 is engaged with the hole portion 15 b provided in the inner cover 15. And fix with screws 18 (FIG. 11). Accordingly, as shown in FIG. 15, since the claw portion 9n of the terminal plate 9 hits the inner cover 15, the protruding amount of the contact portion 9j bent at the base portion 9i of the terminal plate 9 is smaller than that in the no-load state. To be in a precharged state.

  The lid unit 2 is completed by the above assembly process. After “sub-assembly” (assembly of terminal plate 9 and stopper member 13) is performed in advance with respect to terminal plate 9 and stopper member 13, “unit assembly” (after assembling terminal plate 9 and stopper member 13 and assembling other components) Assembly of the entire lid unit 2). This facilitates assembly work.

  Further, in the state where the terminal plate 9 and the stopper member 13 are assembled and fixed to the lid unit 2, the entire extending portion 9 b of the terminal plate 9 cannot be warped. Accordingly, it is possible to avoid the possibility that the engagement between the claw portion 13a of the stopper member 13 and the elongated hole portion 9g of the terminal plate 9 is released and the stopper is detached.

  As shown in FIG. 3, the lid unit 2 is attached together with the lid opening spring 19 and the shaft 20 to bearing portions 21 and 22 disposed at the end of the battery housing portion 3 of the camera body 1, and finally to the camera body 1. The front cover 23 and the rear cover 24 are combined. As a result, as shown in FIG. 1, the assembly of the camera as the electronic apparatus (imaging device in the present embodiment) composed of the camera body 1 and the lid unit 2 is completed.

  Next, the operation of the camera of the present embodiment having the above configuration will be described.

  First, an operation for inserting a battery into the camera will be described. In the state of FIG. 1, when the user slides the operation unit 16a of the lock lever 16 downward and then slides the lid unit 2 to the left, the claw portions 1a and 1b of the camera body 1 as shown in FIG. And the claw portions 8a and 8b of the lid unit 2 are disengaged. Accordingly, the slide plate 14 coupled to the inner side of the outer cover 8 constituting the lid unit 2 is rotated via the bearing portion 14c by the biasing of the lid opening spring 19, so that the lid unit is removed from the camera body 1. 2 opens.

  Here, as described above, the protruding amount of the contact portion 9 d of the terminal plate 9 is suppressed to a small amount because the claw portion 13 a of the stopper member 13 hits the fixing portion 9 a of the terminal plate 9. Therefore, even when the user touches the contact portion 9d of the terminal board 9 with the lid unit 2 opened from the camera body 1, there is no possibility that the contact portion 9d is deformed. Further, since the stopper member 13 covers the periphery of the contact portion 9d of the terminal board 9, there is no possibility that the user touches the edge of the sheet metal (contact portion 9d) to be injured.

  Next, after the user correctly inserts the batteries 4 and 5 into the battery housing 3 of the camera body 1 from the opening, the user rotates the lid unit 2 and then slides the lid unit 2 to the right to close it. Along with this sliding operation, the contact portion 9d of the terminal plate 9 slides on the surface of the positive electrode 5a of the battery 5 to thereby remove the dust and foreign matter at the contact portion and to maintain a good conductivity. Can be obtained.

  In addition, since the sharp protrusions 9e and 9f provided on the contact portion 9d of the terminal board 9 are configured to slide more strongly on the surface of the positive electrode 5a of the battery 5, a refreshing effect can be obtained more reliably. Further, since the sharp protrusions 9k and 9l provided on the contact portion 9j of the terminal board 9 slide on the surface of the negative electrode 4b of the battery 4, a refresh effect can be obtained similarly.

  When the user slides and closes the lid unit 2 to the right as described above, the lock lever 16 slides upward due to the urging of the lever spring 17, so that the lid unit 2 is locked so that it cannot slide to the left. . At the same time, the switch tact portion 16c of the lock lever 16 pushes the lid detection switch 7 to operate it, so that it is detected that the lid unit 2 is properly closed. As a result, the camera can be used as usual.

  FIGS. 16 and 17 show the battery storage state with respect to the camera when it can be used. As shown in FIG. 16, the battery 5 has the positive electrode 5 a in contact with the contact portion 9 d of the terminal plate 9 of the lid unit 2, and the negative electrode 5 b in contact with the negative electrode terminal 11 of the battery storage unit 3. As shown in FIG. 17, the battery 4 has the positive electrode 4 a in contact with the positive electrode terminal 10 of the battery housing portion 3 and the negative electrode 4 b in contact with the contact portion 9 j of the terminal plate 9 of the lid unit 2.

  Thereby, since a predetermined voltage is obtained between the positive electrode terminal 10 and the negative electrode terminal 11 of the battery housing part 3, it is possible to supply power to an electronic circuit or the like inside the camera body. The contact pressure between the positive electrode terminal 10 and the negative electrode terminal 11 is higher in the positive electrode terminal 10 on the battery housing part 3 side than the contact part 9j of the terminal plate 9 of the lid unit 2 and in the battery housing part, as in the conventional example. The negative electrode terminal 11 on the 3 side is set stronger than the contact portion 9 d of the terminal plate 9. Therefore, the batteries 5 and 4 are pressed against the right side (terminal plate 9 side) as shown in FIGS. 16 and 17, respectively.

  Next, a case where a strong vibration impact is applied to the camera due to dropping or the like while the batteries 5 and 4 are pressed against the terminal board 9 will be described.

  FIG. 18 shows a state in which the battery 5 is pressed to the left side in the battery housing portion 3 due to vibration shock, and corresponds to, for example, the case where the camera body 1 is dropped on the floor with the lid unit 2 facing up. In a state where a vibration shock is applied to the camera, the battery 5 moves to a position where it touches the battery abutment surface 3a of the battery housing portion 3, the negative electrode terminal 11 bends by that amount, and the contact portion 9d of the terminal plate 9 of the lid unit 2 Following the direction of the battery 5, the contact state with the positive electrode 5a is maintained. At this time, since the contact portion 9d of the terminal board 9 is precharged and can follow the movement of the battery 5 with a strong precharge force even if the battery 5 moves, the problem of poor contact is less likely to occur.

  FIG. 19 shows a state in which the battery 4 is pressed to the left side (positive electrode terminal 10 side) in the battery housing portion 3 by vibration shock. Also in this case, the battery 4 moves to a position where it hits the battery abutment surface 3b of the battery housing 3, and the positive electrode terminal 10 bends accordingly. At the same time, the contact portion 9j of the terminal plate 9 of the lid unit 2 follows the direction of the battery 4 and maintains the contact state with the negative electrode 4b. At this time, since the contact portion 9j of the terminal board 9 is precharged and can follow up with a strong precharge force even if the battery 4 moves, the problem of poor contact is less likely to occur.

  Next, a case where the battery is inserted into the battery storage unit 3 in the reverse direction (reverse insertion) will be described.

  FIG. 20 shows a state in which the battery 5 is inserted into the battery housing part 3 in the reverse direction. A stopper member 13 formed of an insulating material is attached to the contact portion 9 d of the terminal board 9. Therefore, even if the negative electrode 5b of the battery 5 hits the rib portions 13b and 13c of the stopper member 13, there is a gap between the sharp projections 9e and 9f provided on the contact portion 9d of the terminal plate 9, and the negative electrode 5b of the battery 5 Is prevented from coming into contact with the contact portion 9d. Thereby, the erroneous insertion prevention mechanism of the battery 5 can be configured with high accuracy and simplicity using the stopper member 13.

  FIG. 21 shows a state in which the battery 4 is inserted into the battery housing 3 in the reverse direction. Also in this case, since the insulating member 12 is attached to the positive electrode terminal 10, even if the negative electrode 4 b of the battery 4 hits the insulating member 12, there is a gap between the positive electrode terminal 10 and the negative electrode 4 b of the battery 4 is connected to the positive electrode terminal 10. Prevent contact. Thereby, the erroneous insertion prevention mechanism of the battery 4 can be configured with high accuracy and simplicity using the insulating member 12.

  As described above, according to the present embodiment, when the lid unit 2 of the camera is assembled, a “sub-set” is performed in advance with respect to the terminal plate 9 and the stopper member 13 and then the “unit set” of the entire lid unit. I do. As a result, the assembly work can be facilitated.

  Moreover, the protrusion prevention mechanism which prevents protrusion of a terminal (contact part 9d of the terminal board 9) only by the terminal board 9 and an insulating member (stopper member 13) can be comprised simply. Thereby, it becomes possible to easily manage the protruding amount and protruding pressure of the terminal contacting the battery electrode.

  Moreover, it is set as the structure which cannot warp the whole extension part 9b of the terminal board 9 in the state fixed to the cover unit 2 after the assembly of the terminal board 9 and the stopper member 13. FIG. As a result, it is possible to avoid the possibility of the stopper coming off due to the disengagement between the claw portion 13a of the stopper member 13 and the elongated hole portion 9g of the terminal plate 9.

  Further, when the battery is reversely inserted into the battery housing 3, the stopper member 13 prevents the negative electrode of the battery from coming into contact with the terminal plate 9. As a result, the erroneous battery insertion preventing mechanism can be configured with high accuracy and simplicity using the stopper member 13.

  Further, when the lid unit 2 is closed after the battery is inserted into the storage portion, the contact portion 9d of the terminal plate 9 slides on the surface of the positive electrode of the battery by a sliding operation. As a result, it is possible to obtain a refreshing effect that can remove dust and foreign matters at the contact portion and maintain good conductivity.

  In addition, when the lid unit 2 is closed, the sharp protrusions 9e and 9f of the contact portion 9d of the terminal plate 9 and the sharp protrusions 9k and 9l of the contact portion 9j slide more strongly on the surface of the positive electrode of the battery. It is said. As a result, the refresh effect can be obtained more reliably.
