  Hereinafter, an embodiment as an embodiment of a battery housing according to the present invention will be described with reference to the drawings.

[First embodiment]
A digital still camera 1 shown in FIGS. 1 and 2 has a lens portion 3 provided on the front surface of a camera body 2, and an opening 5 for inserting a battery (storage battery A) 4 is formed on the lower surface of the camera body 2. A lid 6 for opening and closing the opening 5 is provided. The lid 6 is provided with a lock button 7. By sliding the lock button 7, the lock is released and the lid 6 can be opened.

  In the camera body 2, a battery housing case 10 (see FIG. 3) and electronic components (not shown) that perform various operations necessary for photographing are provided. This electronic component is operated by the battery 4 housed in the battery housing 10.

  As shown in FIG. 3, the battery housing case 10 includes a case (housing body) 12 that forms the battery chamber 11 and has an opening 5, and a discharge mechanism 20 provided in the case 12. For convenience of explanation, the lock button 7 is conceptually shown.

  A guide hole 13 extending in the direction of inserting and removing the battery 4 (left and right direction in FIG. 3) is formed in one side wall 12A of the case 12, and a micro switch 14 is provided in the vicinity of the guide hole 13. A hook portion 15 is provided in the vicinity of the opening 5 of the one side wall 12A.

  An electrode terminal (not shown) connected to the electrode of the battery 4 is provided in the case 12.

  The discharge mechanism 20 includes an eject lever 21 that can move along the guide hole 13, and a spring 30 that biases the eject lever 21 toward the opening 5.

  As shown in FIGS. 5 and 6, the eject lever 21 has a plate-like slide portion 22 and a contact formed integrally with the lower surface (in FIG. 5) of the tip portion of the slide portion 22 via a guide portion 23. Part 24.

  A hook 25 is formed on the upper surface (in FIG. 3) of the rear portion of the slide portion 22. One end of the spring 30 is locked to the hook 25, and the other end of the spring 30 is locked to the hook portion 15 of the case 12. Yes. The eject lever 21 is biased toward the opening 5 by the biasing force of the spring 30.

  On the other hand, the guide portion 23 of the eject lever 21 is inserted into the guide hole 13 of the case 12 as shown in FIG. 3, and the abutting portion 24 is disposed in the case 12 and abuts against the front end surface 4A of the battery 4. Is pressed in the discharge direction (direction of the opening 5).

  When the contact portion 24 is a battery (storage battery B) 44 (see FIG. 8) different from the battery 4, for example, a storage battery B having a voltage different from that of the storage battery A, a recessed portion provided at the tip of the battery 44 that is the storage battery B 44A is set to be inserted.

  When the lock of the lid 6 is released by operating the lock button 7, as shown in FIG. 7, the eject lever 21 moves to the right by the urging force of the spring 30, and the movement of the eject lever 21 by the rightward movement is performed. The contact part 24 causes the battery 4 to be discharged from the opening 5. That is, the battery 4 can be discharged from the opening 5 regardless of its own weight.

  The micro switch 14 is turned on when the slide portion 22 of the eject lever 21 comes to a predetermined position shown in FIGS. That is, when the battery 4 is stored in the battery chamber 11 of the case 12 as shown in FIG. 3, the micro switch 14 detects the slide portion 22 and is turned on.

  When the battery 4 is housed in the battery chamber 11, the electrode of the battery 4 is connected to an electrode terminal (not shown) in the case 12.

  When another battery 44 is housed in the battery chamber 11 of the case 12 as shown in FIG. 8 instead of the battery 4, the contact portion 24 of the eject lever 21 is inserted into the recess 44 </ b> A of the battery 44. For this reason, the slide part 22 of the eject lever 21 stops at the position of the solid line shown in FIG. 9, and does not move to the position of the chain line (predetermined position). For this reason, the microswitch 14 is turned off.

  Thus, since the microswitch 14 is turned on when the battery 4 is used and the microswitch 14 is turned off when the battery 44 is used, the batteries 4 and 44 can be identified by turning the microswitch 14 on and off. Moreover, since the microswitch 14 is turned on / off by detection of the slide portion 22 of the eject lever 21 that discharges the batteries 4 and 44, it is not necessary to provide a dedicated mechanism for identifying the batteries 4 and 44. .

  As shown in FIG. 8, when the battery 44 is stored in the battery chamber 11 of the case 12, the battery 44 is stored in the same state as the battery 4, so that the electrode of the battery 44 is connected to the electrode terminal in the case 12.

  When the lock button 7 is unlocked, the lid 6 can be opened, so that the contact portion 24 of the eject lever 21 discharges the battery 44 from the opening 5 of the case 12 by the biasing force of the spring 30 as shown in FIG. The battery 44 can be discharged from the opening 5 regardless of its own weight.

  11 and 12 show another example of the eject lever 21. The recess 22A and the protrusion 22B are provided in the slide portion 22 of the eject lever 21, and the recess 22A and the protrusion 22B are detected by the microswitch 14. Thus, the batteries 4 and 44 accommodated therein are identified.

According to the first embodiment, since the batteries 4 and 44 can be discriminated by the position of the eject lever 21, it is necessary to provide a dedicated switching structure for battery discrimination separately from the eject lever 21 for discharging the battery. Absent. For this reason, the space occupation rate of the battery housing 10 can be reduced, and the number of parts can be reduced, so that the cost can be reduced.
[Second Embodiment]
FIG. 13 shows a battery housing case 100 of the second embodiment. In the second embodiment, the top plate wall portion 12T of the case 12 is provided with a projection portion (incorrect insertion preventing means) 101 for preventing erroneous insertion.

  The battery housing case 100 is configured such that different batteries (storage battery A) 54 and (storage battery B) 64 (see FIG. 14) can be identified, and the battery 54 has a recess 54A. The battery 64 has a recess 64A that is narrower in the left-right direction (in FIGS. 13 and 14) than the recess 54A.

  Although the entire contact portion 124 of the eject lever 121 enters the recess 54A of the battery 54, the contact portion 124 is set to be approximately half of the recess 64A of the battery 64 as shown in FIG.

  When the battery 64 is stored in the case 12 as shown in FIG. 14, the microswitch 114 is turned on by detecting the slide portion 22 of the eject lever 121, and the battery 54 is stored in the case 12 as shown in FIG. And the slide portion 22 is not detected and remains off.

  That is, in the second embodiment, the types of the batteries 54 and 64 can be determined by turning on / off the microswitch 114 as in the first embodiment.

  Incidentally, the total length of the width of the protrusion 101 in the left-right direction (in FIG. 13), the width of the contact portion 124 in the left-right direction, and the length of the battery 54 (battery 64) is the same as that of the battery chamber 11 of the case 12. It is set longer than the length L0 in the left-right direction (see FIG. 19).

  As shown in FIG. 15, when the battery 54 is inserted into the case 12 in the reverse direction (the front end portion and the rear end portion are reversed), the rear end 54 a of the battery 54 comes into contact with the contact portion 124 of the eject lever 121, Further, since the abutting portion 124 abuts on the protruding portion 101 in the case 12, the total length is set longer than the length L 0 of the battery chamber 11, so that the tip end portion 54 B of the battery 54 is It will protrude from the opening 5 of the case 12, and the battery 54 cannot be stored in the case 12. As a result, it can be seen that the battery 54 is erroneously inserted.

  As shown in FIG. 16, when the battery 64 is inserted into the case 12 in the same manner as described above, it can be seen that the tip 64B of the battery 64 protrudes from the opening 5 of the case 12 and the battery 64 is erroneously inserted. become.

  When the batteries 54 and 64 are inserted into the case 12 upside down, that is, the batteries 54 and 64 are inserted into the case 12 so that the recesses 54A and 64A are located at the positions indicated by chain lines in FIGS. Even in this case, the rear part of the battery protrudes from the opening 5 of the case 12, so that the erroneous insertion of the batteries 54 and 64 can be recognized.

  According to the second embodiment, since the protrusion 101 for preventing erroneous insertion is provided, the battery 54 cannot be physically inserted into the battery chamber 11 or the lid 6 can be locked in the erroneous battery insertion direction. 64 can be prevented from being erroneously inserted.

This second embodiment can also obtain the same effects as the first embodiment.
[Third embodiment]
17 and 18 show a battery housing case 200 of the third embodiment. The contact portion 224 of the eject lever 221 of the battery housing case 200 has a rectangular parallelepiped base portion 224A and a protrusion 224B that is integrally formed on the right side surface of the base portion 224A and protrudes to the right.

  On the other hand, for example, the battery (storage battery A) 74 is formed with a recess 74A into which the base 224A of the contact portion 224 of the eject lever 221 is inserted and a recess 74B into which the projection 224B of the contact portion 224 is inserted. ing.

  On the other hand, the battery (storage battery B) 84 different from the battery 74 includes a recess 84A into which the base 224A of the contact portion 224 of the eject lever 221 is inserted, and a recess 84B into which the projection 224B of the contact portion 224 is inserted. Is formed. The recess 84A of the battery 84 has a left and right (in FIG. 18) width W1 smaller than the width W2 of the recess 74A of the battery 74.

  When the battery 74 is housed in the case 12 as shown in FIG. 17, the base 224A and the protrusion 224B of the abutting portion 224 of the eject lever 221 are inserted into the concave portions 74A and 74B of the battery 74. Since the movement of 221 in the left direction (in FIG. 17) is small, the micro switch 214 is turned off without detecting the slide portion 22 of the eject lever 221.

  When the battery 84 is housed in the case 12 as shown in FIG. 18, the base 224A and the protrusion 224B of the contact portion 224 of the eject lever 221 are inserted into the recesses 84A and 84B of the battery 84. Since the width W1 is narrow, the contact portion 224 protrudes from the recess 84A. Therefore, since the eject lever 221 moves to the left more than in the case of FIG. 17, the micro switch 214 detects the slide portion 22 of the eject lever 221 and turns it on.

  As described above, the types of the batteries 74 and 84 can be determined by turning the microswitch 214 on and off.

  19 and 20, the value obtained by adding the length L1 of the contact portion 224 of the eject lever 221 and the length L2 of the batteries 74 and 84 is larger than the length L0 of the battery chamber 11 of the case 12. Is set.

  For this reason, when the battery 74 is inserted into the case 12 in the reverse direction as shown in FIG. 19, the rear part of the battery 74 comes into contact with the protrusion 224 </ b> B of the contact part 224 of the eject lever 221. Although it is made to contact | abut to the top-plate wall part 12T of case 12, the value which added the length L1 of the contact part 224 and the length L2 of the battery 74 is set larger than the length L0 of the battery chamber 11 of the case 12. As a result, the tip of the battery 74 protrudes from the opening 5 of the case 12. As a result, erroneous insertion of the battery 74 can be understood.

  Similarly, when the battery 84 is inserted into the case 12 in the reverse direction as shown in FIG. 20, the tip end portion of the battery 84 protrudes from the opening 5 of the case 12, and the erroneous insertion of the battery 84 can be recognized.

  Even when the batteries 74 and 84 are inserted in the case 12 with the front and back sides reversed, the rear part of the battery protrudes from the opening 5 of the case 12 as in the second embodiment, so that the erroneous insertion of the batteries 74 and 84 can be recognized. Become.

  That is, the contact portion 224 functions as an erroneous insertion prevention unit that prevents erroneous insertion of the batteries 74 and 84.

This third embodiment can also obtain the same effect as the first and second embodiments.
[Fourth embodiment]
21 to 23 show a battery housing case 300 of the fourth embodiment. The battery housing case 300 is formed by forming a protrusion 12H for preventing erroneous insertion across the top wall 12T and the side wall 12S of the case 12.

  The battery housing case 300 has an abutting portion 324 of an eject lever 321 that enters the recessed portion 304A of the battery (storage battery A) 304. When the battery 304 is correctly stored in the case 12, the recessed portion 304A of the battery 304 has As shown in FIG. 21, the abutting portion 324 of the eject lever 321 and a part of the protruding portion 12H of the case 12 enter.

  As shown in FIG. 24, when the battery 304 is inserted in the reverse direction, the rear end of the battery 304 abuts against the protrusion 12 </ b> H so that the front end of the battery 304 protrudes from the opening 5 of the case 12. This protrusion prevents erroneous insertion of the battery 304.

  The battery housing case 300 can distinguish between the battery 304 and a battery (storage battery B) 344 (see FIG. 25) different from the battery 304. The width W3 of the recess 344A of the battery 344 is the battery 304. It is set narrower than the width W4 of the recess 304A. When the battery 304 is housed in the case 12 as shown in FIG. 21, the contact portion 324 of the eject lever 321 is inserted into the concave portion 304A of the battery 304, so that the eject lever 321 moves to the left (in FIG. 21). Therefore, the micro switch 314 is turned off without detecting the slide portion 22 of the eject lever 321.

  When the battery 344 is housed in the case 12 as shown in FIG. 25, the contact portion 324 of the eject lever 321 is inserted into the recess 344A of the battery 344, but the width W3 of the recess 344A is equal to the width of the recess 304A of the battery 304. Since the width is set narrower than the width W4, the contact portion 324 protrudes from the recess 344A. For this reason, since the eject lever 321 moves to the left more than in the case of FIG. 21, the micro switch 314 detects the slide portion 22 of the eject lever 321 and turns on.

  As described above, the batteries 304 and 344 can be identified by turning the microswitch 314 on and off.

  When the battery 344 is inserted in the reverse direction, the rear end of the battery 344 contacts the protrusion 12H and the tip of the battery 344 is the opening of the case 12, as in the reverse insertion of the battery 304 (see FIG. 24). Thus, the battery 344 can be prevented from being erroneously inserted.

  Even when the batteries 304 and 344 are inserted into the case 12 with the front and back sides reversed, the rear ends of the batteries 304 and 344 protrude from the opening 5 of the case 12 because the tip of the battery 344 contacts the protrusion 12H. Incorrect insertion can be prevented.

  That is, the contact portion 324 functions as an erroneous insertion prevention means for preventing erroneous insertion of the batteries 304 and 344.

In the fourth embodiment, the same effect as in the first and second embodiments can be obtained.
[Other examples]
26 and 27 show a case where a protrusion 12H2 for preventing erroneous insertion is provided on the top plate wall 12T when the case 12 is not provided with a side wall 12S in order to avoid interference with other devices.

  In this case, as shown in FIG. 28, a notch 324A may be provided in the contact portion 324 of the eject lever 321 to avoid interference with the protrusion 12H3.

  In any of the above embodiments, two types of batteries, ie, a dry battery and a storage battery, are identified. However, the present invention is not limited to this. For example, the width of the recess provided in the battery can be differentiated according to the voltage so that the voltage of the battery can be identified. The position of the lever slide portion may be different for each type of battery, and three or more types of battery may be identified by detecting the position of the slide portion of the eject lever with a plurality of micro switches.

  The present invention is not limited to the above-described embodiments, and design changes and additions are permitted without departing from the scope of the claimed invention.
