The box lid 3 is formed in a rectangular shape that is open to the lower side (see 1 to 6 ). The receiving box 4 is formed in a rectangular shape which is open to the upper side. In a state where the case 2 is configured by connecting the box lid 3 and the receiving box 4 vertically, is the interior of the housing 2 designed as a recording room.

In the recording room of the housing 2 are a separator 5, cells 6 and 6 , Connecting plates 7, 8 and 8 and a circuit substrate 9 are arranged (see 1 ). The separator 5 is fixed in the receiving box 4. The cells 6 and 6 are arranged in a state in which the cells are separated horizontally by the separator 5. The connecting plate 7 is connected to one terminal of each of the cells 6 and 6 and has a lower end portion connected to an electrode terminal formed on the lower surface of the circuit substrate 9, which is not shown in the drawing. The connecting plates 8 and 8 are connected to the other terminals of the cells 6 and 6 connected and have lower end portions which are connected to formed on the lower surface of the circuit substrate 9 electrode terminals, which are not shown in the drawing. The circuit substrate 9 is mounted in the receiving box 4 and is in a state of being covered with the separator 5 except for a portion from the upper side. The housing 2 contains a top surface 11 , a lower surface 12 , Side surfaces 13 and 13 , a front surface 14 and a rear surface 15 as outer surfaces 10. The dimension of the housing 2 is larger in a front-rear direction (longitudinal direction) than the dimension in a left-right direction (width direction), and the dimension in the horizontal direction (width direction) is larger than the dimension in the vertical direction (height direction) (see FIG 1 to 6 ). In the housing 2 are between the upper surface 11 and the side surfaces 13 and 13 inclined surfaces 16 and 16 are formed. The inclined surfaces 16 and 16 extend as they approach the side surfaces 13 and 13 from the upper surface 11 to the lower surface.

The upper surface 11 , the lower surface 12 , the side surfaces 13 and 13 , the front surface 14, the rear surface 15 and the inclined surfaces 16 and 16 are all formed as outer surfaces 17, 17,.

At the two horizontal side portions of the lower end portion of the housing 2 are notches 2a and 2a formed. The score 2a is open to the side surface (the left side or the right side), the lower side, the front side and the rear side, and is defined by a height-different area 18 extending to the front / rear side facing the lower side, and a grooving surface 19 formed extending to the front / rear side facing the lateral side. The outer edge of the height-varying surface 18 goes from the bottom of the side surface 13 out. The upper edge of the grooving surface 19 goes from the inner edge of the height-differentiated surface 18 and their bottom edge goes from the bottom of the page 12 out. The height-varying area 18 and the grooving surface 19 are formed so as to be continuous over the front surface 14 to the rear surface 15.

When fixing the battery 1 in the battery mounting unit 83, moreover, the terminal connection unit 93 of the charger becomes 80 between the wall portions 29b and 29b of the battery 1 introduced. As a gap, dimensional tolerances and the like, to ensure trouble-free insertion of the battery 1 in the battery mounting unit 83 between the battery 1 and the charger 80 There is a possibility that the battery 1 is introduced into the battery mounting unit 83 in a state of being in relation to the charger 80 is tilted or offset to the left or right side (see 32 ).

In a case where the battery 1 in the inclined state or staggered state in the charger 80 is introduced, since the wall portions 29b and 29b are formed as inclined surfaces which are spaced apart in the horizontal direction, upon advancement of the wall portions to a more forward side, the terminal connection unit 93 is guided to the wall portions 29b and 29b to be so the connector 33 approaches.

Accordingly, the connection terminals become 35 . 35 and 35 and the connector 33 the battery 1 reliable with the electrode connections 95 . 95 and 95 the terminal connection unit 93 (see 33 ). At this time, the protruding positioning portions 94a and 94a of the terminal connection unit 93 respectively become the positioning grooves 37 and 37 of the connector 33 introduced, and there is the positioning of the connector 33 with respect to the terminal connection unit 93.

<Summary>

In the battery 1 is, as described above, a concave arrangement part 27 of the housing 2 forming surface as the concave-part-forming surface 29, and the central portion 29c, which is a part of the concave-part-forming surface 29, between the front surface 14 of the outer surface 10 and the connector 33 intended.

Because the front surface 33a of the connector 33 at a further inside than the front surface 14 of the housing 2 lying side in the housing 2 is positioned, a possible damage or possible scratching of the connector 33 should this fall down or the like, reduced, and there may be an excellent connection state of the connection terminal 35 be ensured with the electrode terminals 61 and 95.

Because in a case impact, an impact force is not easy on the connector 33 can be transferred, it is not easy to crack in the solder material, which is used to connect the connection terminal 35 is used with the circuit substrate 9, and the occurrence of a defect in the electrical connection can be reduced. As a possible damage or possible scratching of the connector 33 In addition, the connection port becomes smaller 35 not easily exposed from the receptacle 34, and it can be a high quality of the connector 33 be guaranteed.

Although in the above description an example has been presented in which the front surface 33a of the connector 33 on a side inside the case 2 as the front surface 14 of the housing 2 For example, the bottom surface 33b of the connector may be positioned 33 on a side inside the case 2 as the bottom surface 12 of the housing 2 be positioned (see 34 ).

In this way, even in a case where the bottom surface 33b of the connector 33 on a side inside in the case 2 as the bottom surface 12 of the housing 2 is positioned, possible damage and possible scratching of the connector 33 should this fall down or the like, reduced, and there may be an excellent connection state of the connection terminal 35 with the electrode connections 61 and 95 be guaranteed.

The configuration may also be, for example, such that the front surface 33a of the connector 33 on a side inside the case 2 as the front surface 14 of the housing 2 is positioned and the bottom surface 33b of the connector 33 on a side inside the case 2 as the bottom surface 12 of the housing 2 is positioned (see 35 ). In a case where the front surface 33a on a more inner side in the housing 2 as the front surface 14 is positioned and the lower surface 33b at a more inner side in the housing 2 as the bottom surface 12 is positioned, the entire connector 33 in this way on the inside of the case 2 be positioned. Accordingly, possible damage and possible scratching of the connector 33 should this fall down or the like, further reduced, and there may be an excellent connection state of the connection terminal 35 be ensured with the electrode terminals 61 and 95.

In the battery 1 moreover, the concave arrangement part 27 is in a connecting direction of the connection terminal 35 with the electrode terminals 61 and 95 open, and a central portion 29c which is the concave-part-forming surface 29 is in the connecting direction between the outer surface 10 and the connector 33 intended.

Because the connector 33 on a side inside the case 2 when the outer surface 10 is positioned, the electrode terminals accordingly become 61 and 95 at the time of connection to the inside of the concave placement part 27, and the size of the connection device (the imaging device 50 or the charger 80 ) in the connection direction can be downsized.

A part of the concave-part-forming surface 29 is further formed as an inclined surface, and the opening portion of the concave-arranging part 27 is further spaced apart the part from the connector 33 in the opening direction (connecting direction) of the concave arrangement part 27 increases.

Accordingly, since a part of the concave-part-forming surface 29 serves as a guide surface at the time of inserting the electrode terminals 61 and 95 into the concave arrangement part 27, an excellent connection state between the connection terminal 35 and the electrode terminals 61 and 95 be guaranteed.

Further, the concave-part-forming surface 29 includes a pair of wall portions 29b and 29b positioned to be spaced from each other in a direction orthogonal to the connecting direction, and the wall portions 29b and 29b are formed as inclined surfaces that are in the connecting direction are further spaced from each other.

Since the wall portions 29b and 29b at the time of insertion of the electrode terminals 61 and 95 Accordingly, in the concave arrangement part 27 serving as guide surfaces, a particularly excellent connection state between the connection terminal 35 and the electrode terminals 61 and 95 be guaranteed.

Moreover, although in the above-mentioned description, an example in which a pair of the wall portions 29b and 29b are formed as inclined surfaces with the surfaces spaced from each other in the connecting direction, for example, the one wall portion 29b may be referred to as an inclined surface an opening area of the concave arrangement part 27 which increases along the connecting direction (see FIG 36 ).

In the battery 1 In addition, the central portion 29c of the concave-part-forming surface 29 may be further formed as an inclined surface having an opening portion of the concave-arranging member 27, which is further spaced apart from the middle portion of the connector 33 increases in the connection direction (see 37 ).

By forming the middle portion 29c as the inclined surface, the middle portion 29c serves at the time of inserting the electrode terminals 61 and 95 in the concave arrangement part 27 in this way as a guide surface, and accordingly, a particularly excellent connection state between the connection terminal 35 and the electrode terminals 61 and 95 be guaranteed. In such a case, the wall portions 29b and 29b may be formed as inclined surfaces in addition to the middle portion 29c, a wall portion 29b may be formed as an inclined surface in addition to the middle portion 29c, or only the middle portion 29c may be formed as an inclined surface be educated.

Although the inclination angle of the wall portion 29b or the central portion 29c with respect to the connecting direction is arbitrary, it is preferable here, for example, that the inclination angle is larger than 0 degrees and equal to or smaller than 45 degrees.

By configuring the inclination angle of the wall portion 29b or the middle portion 29c to be greater than 0 degrees and equal to or less than 45 degrees, the inclination angle of the concave-part-forming surface 29 serving as a guide surface is an acute angle, and accordingly, those to the guide surface guided electrode connections 61 and 95 be easily inserted into the concave assembly part 27. Although in the description set forth above, as an example charger 80 of a type in which the battery 1 Further, a charger is inserted from the upper side into the concave attachment part 83a and then pushed to the front side for attachment 80A another type in which the battery 1 by inserting the battery 1 is fastened from the upper side (see 38 ).

The entire charger 80A is arranged, for example, as a battery mounting unit 83A, and a concave attachment portion 83b, which is open to the upper side, is formed in the battery mounting unit 83A. In the battery mounting unit 83A, a terminal connection unit 96 having electrode terminals is disposed. The battery 1 is in one direction in the concave mounting portion 83b of the charger 80A introduced, in which the front surface 14 faces the lower side.

In such a case, by forming at least one of the wall portions 29b and 29b and the middle portion 29c of the battery 1 as an inclined surface (guide surface), the terminal connection unit 96 corresponding to the dead weight of the battery 1 at the time of insertion of the battery 1 guided into the concave attachment part 83b to the inclined surface. Accordingly, a light and excellent connection state of the battery 1 for the charger 80A be guaranteed.

In the battery 1 is in the case 2 the score 2a according to the of the side surface 13 outgoing altitudinal area 18 and that of the lower surface 12 outgoing grooving surface 19 formed, the first guided groove 22 , the second guided groove 23 and the third guided groove 24 leading to the grooving surface 19 are open, are formed, and the first guided groove 22 , the second guided groove 23 and the third guided groove 24 are at a lower level than the altitude difference 18 lying face 12 positioned.

Accordingly, the first guided groove 22 , the second guided groove 23 , the third guided groove 24 and the height-varying area 18 not positioned continuously, but part of the grooving surface 19 is between the first guided groove 22 , the second guided groove 23 , the third guided groove 24 and the height-varying area 18 positioned. Therefore, there are the grooving surface 19 and the height-varying area 18 closer to the cell 6 as in a case where the first guided groove 22 , the second guided groove 23 , the third guided groove 24 and the height-varying area 18 are positioned throughout; the size of the battery 1 can be downsized.

Because the notches 2a and 2a in each case from the two side surfaces 13 and 13 outgoing digits are formed, there are the notches 2a and 2a in addition, on both sides of the two side surfaces 13 and 13 , and the outer surface 10 of the housing 2 is positioned so that it is in two places near the cells 6 and 6 is; and the size of the battery 1 can be further reduced.

Further, the first guided grooves 22 and 22 , the second guided grooves 23 and 23 and the third guided grooves 24 and 24 towards the connection of the connection terminal 35 with the electrode connections 61 and 95 formed spaced from each other.

Accordingly, portions are between the first guided groove 22 , the second guided groove 23 and the third guided groove 24 in the case 2 as protruding portions with respect to the first guided groove 22 , the second guided groove 23 and the third guided groove 24 formed, and therefore serve the protruding portions as reinforcing ribs, and the strength of the housing 2 will be improved.

<Another configuration example for the battery>

Below is another configuration example for the battery 1 described (see 39 to 44 ).

It can be at least on both horizontal sides of the battery 1 concave engaging parts 39 and 39 be educated (see 39 ). The concave engagement parts 39 and 39 are open to the second guided grooves 23 and 23, for example.

The battery 1 in which such concave engaging parts 39 and 39 are formed is, for example, in a by a charger 80B held state connected. The charger 80B includes a main body 97, holding arms 98 and 98 protruding from the main body 97 to the rear side, and a terminal connection unit 99 including electrode terminals arranged in the main body 97 in the rear-side projecting state.

In the main body 97, an operation knob 97a is disposed, and by operation of the operation knob 97a, the support arms 98 and 98 are operated in a spacing direction from each other.

The holding arms 98 and 98 are as protruding engaging parts 98a and 98a arranged to bend in directions in which the tip end portions approach each other. In the tip end portions of the holding arms 98 and 98, there are formed sliding surfaces 98b and 98b which are inclined in directions approaching each other when approaching the main body 97. The support arms 98 and 98 are not shown in the drawings Springs disposed in the main body 97 are biased in directions approaching each other.

When the battery 1 regarding the charger 80B Moves to the front, becomes the front edge of the battery 1 pushed toward the sliding surfaces 98b and 98b to cause the holding arms 98 and 98 to move in spaced apart directions against the biasing forces of the springs, and the holding arms 98 and 98 are respectively inserted into the first guided grooves 22 and 22 introduced. The holding arms 98 and 98 are respectively relative to the first guided grooves 22 and 22 to the second guided grooves 23 and 23 moves and temporarily at the groove forming surfaces 19 and 19 of the first guided grooves 22 and 22 placed and moved again in directions approaching each other to enter the second guided grooves 23 and 23 to be introduced, and the protruding engaging parts 98a and 98a are each with the concave engaging parts 39 and 39 engaged (see 40 ).

The protruding engaging parts 98a and 98a of the charger 80B are engaged with the concave engaging parts 39 and 39 are engaged and in a state in which they are the battery 1 jam horizontally from both sides, eliminating the battery 1 through the charger 80B is held. When the protruding engaging parts 98a and 98a each with the concave engagement parts 39 and 39 be engaged simultaneously becomes the connector 33 connected to the terminal connection unit 99.

In a case where holding the battery 1 in the charger 80B is released, the releasing operation by moving the holding arms 98 and 98 in the spacing directions from each other by operating the operation knob 97 a for releasing the engagement state of the protruding engaging parts 98a and 98a with the concave engagement parts 39 and 39 and pulling away from each other of the battery 1 and the charger 80B.

Although in the above description an example has been made in which the concave engaging parts 39 and 39 each to the second guided grooves 23 and 23 open, the concave engaging parts can 39 and 39 beyond each to the introduction grooves 24 and 24 be open. In a case where the concave engaging parts 39 and 39 to the guided grooves 23 and 23 open, however, are the protruding engaging parts 98a and 98a of the charger 80B in the guided grooves 23 and 23 inserted and guided, and accordingly, the protruding engaging parts 98a and 98a with the concave engagement parts 39 and 39 be reliably engaged.

As described above, by forming the concave engaging parts 39 and 39 with which the protruding engaging parts 98a and 98a , each in opposite directions in the housing 2 open, be engaged, the battery 1 by engaging the projecting engagement members 98a and 98a with the concave engagement parts 39 and 39 can be held from the opposite sides, and accordingly the battery 1 easily kept in a stable condition.

Although in the above description an example has been made in which the concave engaging parts 39 and 39 on the two horizontal sides of the battery 1 are formed, moreover, for example, in addition to the concave engagement parts 39 and 39 the two horizontal sides a concave engaging part 39 be formed, leading to the upper surface 11 and / or the lower surface 12 is open (see 41 ). In this way, by forming the concave engaging part 39 facing the upper surface 11 or the lower surface 12 is open orthogonal to the surfaces of the two horizontal sides facing to opposite sides, the battery 1 by engaging the projecting engagement members 98a . 98a and 98a with the concave engagement parts 39 . 39 and 39 from opposite sides and a side orthogonal to the opposite side, and accordingly the battery can 1 be kept in a more stable condition.

Since the concave engaging part 39 is formed in a region in which the second guided groove 23 is provided, the projecting engaging part 98a beyond that by the second guided groove 23 for engagement with the concave engagement part 39 guided, and accordingly, the engagement of the protruding engaging part 98a with the concave engaging part 39 be carried out easily and reliably.

The concave engaging part 39 can also be formed in a region in which the first guided groove 22 is provided (see 42 ), instead of the area where the second guided groove 23 is provided, or it may be formed in an area where the third guided groove 24 is provided (see 43 ).

In particular, in a case where the concave engaging part 39 is formed in the region in which the first guided groove 22 is provided, is the concave engaging part 39 provided in an area where the first guided groove 22 is positioned in the connecting direction on the front end side.

When fixing the battery 1 in the charger 80B Accordingly, it is not necessary that the projecting engagement part 98a about the Nutbildungsfläche 19 extends, and the engagement of the protruding engaging part 98a with the concave engaging part 39 can be done easily and quickly.

When the protruding engaging part 98a with the concave engaging part 39 Further, the electrode terminals of the terminal connection unit 99 are connected to the connection terminals 35 of the connector 33 connected. Because the engagement of the protruding engaging part 98a with the concave engaging part 39 and the connection of the electrode terminals with the connection terminals 35 are performed simultaneously, it is therefore not necessary, the engagement operation of the protruding engaging part 98a with the concave engaging part 39 and the connection operation of the electrode terminals with the connection terminals 35 individually, and operability can be improved.

In addition, the concave engaging part 39 in a region other than the region where the first guided groove 22 , the second guided groove 23 or the third guided groove 24 are provided, can be formed and can in a Nutbildungsfläche 19 open state are formed. For example, in lower end portions of the rear end portions of the groove forming surfaces 19 and 19 concave engaging parts 39 and 39 are formed, which are open at least to the lower side and rear side (see 44 ). By configuring the concave engaging parts 39 and 39 in that they are respectively in the lower end portions of the rear end portions of the groove forming surfaces 19 and 19 are formed, the battery can 1 through the charger 80 or the like, for example, by arranging two engaging holding portions 92 and 92 in the charger 80 or the like, and locking the protruding locking portions 92a and 92a of the engagement holding portions 92 and 92 in the open edges of the concave engaging portions 39 and 39 being held.

Because the concave engaging parts 39 and 39 at a farther than the rear surface 15 of the battery 1 In this case, the protruding locking portions 92a and 92a are also located at the front side and the length of the charger 80 or the like in the forward / backward direction is shortened, reducing the size of the charger 80 or the like can be downsized.

<Configuration and the like of identification groove>

Next, the configuration and the like of the identification groove 30 will be described (see 45 to 56 ).

The above-described identification groove 30 is configured by a first identification part 31 and second identification parts 32 having mutually different lengths in the front-rear direction, and the first identification part 31 and the second identification parts 32 are horizontally continuous (see FIG 45 and an upper tier of 46 ). The first identification part 31 and the second identification parts 32 are different.

Meanwhile, in a related art battery, a first identification groove A corresponding to the first identification part 31 and a second identification groove B corresponding to the second identification parts 32 are formed with a predetermined gap for their horizontal spacing from each other (see a lower step of FIG 46 ).

The horizontal width of the identification groove is generally determined based on the flowability of a resin at the time of molding a case, the degree of flame retardance, and the like. Moreover, the width of the identification groove is formed in a size for securing the strength of a protruding identification portion to be inserted in the identification groove. In particular, in a case where the width of the identification groove is small, it is necessary to make the width of the inserted protruding identification portion small. However, in a case where the width of the protruding identification portion is small, the strength of the protruding identification portion is reduced, and there is a great possibility of damage or cracking. Accordingly, in order to ensure the strength of the protruding identification portion having at least a predetermined strength, it is necessary to configure the width with at least predetermined dimensions, and it is necessary to configure the width of the identification groove to be at least a predetermined width. The horizontal width of the concave attachment part 83a of the charger 80 On the other hand, it is a margin (looseness) to ensure easy insertion of the battery 1 is used in the concave attachment part 83a, larger than the horizontal width of the battery 1 , Accordingly, as the width of the identification groove, a dimension corresponding to a span required for reliable insertion of the protruding identification portion is required. Moreover, the width of the identification groove is formed in a dimension regarded as the dimensional tolerance or mounting allowance for each section, and the width of the identification groove is set to have such a margin. Further, in a battery of the related art, a predetermined gap H between the first identification groove A and the second identification groove B, and a width of at least a predetermined dimension is required for ensuring that the strength of the gap H has at least a predetermined strength.

Thus, in a battery of the related art, when the width of the protruding identification portion to be inserted in both the first identification groove A and the second identification groove B is W1, the width of both the first identification groove A and the second identification groove B is "W1 + C", where a margin (looseness + dimensional tolerance) is C. In addition, since the gap H between the first identification groove A and the second identification groove B is required, a horizontal dimension Wp required for the housing for forming the first identification groove A and the second identification groove B is "2W1 + 2C + H". ,

In the battery 1 meanwhile, the first identification part 31 corresponding to the first identification groove A and the second identification parts 32 corresponding to the second identification groove B are formed horizontally in the horizontal direction (see an upper stage of FIG 46 ). Since the gap H is not required, accordingly, a horizontal dimension W, which in the housing 2 for forming the identification groove 30 configured by the first identifying part 31 and the second identifying parts 32, at most a measure of "2W1 + 2C".

Moreover, in the identification groove 30, since the first identification part 31 and the second identification parts 32 are continuous in the horizontal direction, a span C is out of the span 2C is not required for the measure W, and the measure W is a measure of at most "2W1 + 2C".

Further, since the protruding identification portion to be inserted into the second identification parts 32 of shorter length can be partially inserted into the first identification part 31, the width of the second identification parts 32 can be configured to be smaller than the width W1, and if the dimension, α, the dimension W is "2W1-a + C".

The horizontal dimension W, which is required to allow the housing 2 the identification groove 30 is accordingly reduced by "C + H + a" from the horizontal dimension Wp required in the case of a related art battery, and the size of the battery 1 can be reduced by this amount.

For example, although the above description has set forth an example in which the identification groove 30 is configured by the first identification part 31 and the second identification parts 32 each having a rectangular shape, the identification groove 30 may be formed in a shape where the lower inner surfaces 31a and 32a are inclined (see 47 ). In the identification groove 30 having the shape in which the lower inner surfaces 31 a and 43 a are inclined, a left-side or right-side portion is configured as a first identifying part 31, and a portion of the other side is configured as a second identifying part 32.

Since there is no height difference in the identification groove 30 in which the lower inner surfaces 31a and 42a are inclined, the identification groove 30 can be housed 2 be easily trained.

Next are examples of the batteries 1A and 1B with identification grooves different from those of the battery 1 distinguish, described (see 48 and 49 ).

As described above, are in the battery 1 two identification grooves 30 and 30 are formed horizontally spaced apart. For example, the battery 1 is a medium-capacity type whose maximum charge capacity is standard.

The battery 1A For example, it is a high capacity type whose maximum charge capacity is greater than that of the battery 1 is. In the battery 1A An identification groove 30 and an identification groove 30A are formed (see FIG 48 ). The identification groove 30 </ b> A is configured by a first identification part 31 </ b> A that is longer than the first identification part 31 in the front-rear direction and the second identification parts 32.

The battery 1B For example, a low capacity type whose maximum charge capacity is smaller than that of the battery 1 is. In the battery 1B an identification groove 30 is formed (see 49 ). Next, configuration examples of the battery mounting unit of a connector to which the battery is attached will be explained 1 , the battery 1A or the battery 1B attached is described (see 50 to 53 ).

As connecting devices, for example, a low-power camera that can be driven by a low power, a medium-power camera that can be driven by a higher power than that of the low-power camera, a high-performance camera that is characterized by a performance higher than which is the camera with medium power, can be powered, and a charger 80 intended.

In the battery mounting unit of the low-power camera, the terminal connection unit 59 is disposed, but no protruding identification portion inserted in the identification groove 30 or the like is disposed (refer to FIG 50 ).

In a battery mounting unit of the medium power camera, the terminal connection unit 59 is disposed, and a protruding identification portion 90B is disposed on the lateral side of the terminal connection unit 59 (see FIG 51 ). The protruding identification portion 90B has such a length that the entire protruding identification portion 90B can be inserted into the first identification part 31 or the first identification part 31A. In a battery mounting unit of the high-power camera, the terminal connection unit 59 is disposed, and a protruding identification portion 90C is disposed on the lateral side of the terminal connection unit 59 (see FIG 52 ). The protruding identification portion 90C has a greater length than that of the protruding identification portion 90B and has a length such that the entire protruding identification portion 90C is not inserted into the first identification part 31, but the entire protruding identification portion can be inserted into the first identification part 31A. In the battery mounting unit 83 of the charger 80 As described above, the terminal connection unit 93 is disposed, and the protruding identification section 90 is disposed on the lateral side of the terminal connection unit 93 (see FIG 53 ). The protruding identification portion 90 is configured by the long portion 90a and a short portion 90b.

Next, an example of the distinguishability of the above-described identification grooves 30 and 30A will be described (see 54 ).

The following is an example of the distinctness of the battery 1 , the battery 1A and the battery 1B for the low power camera, the medium power camera, the high power camera, and the charger 80 described. In 54 "J" indicates that the battery can be mounted in a camera or a charger, and "N" indicates that the battery can not be mounted in a camera or in a charger.

The battery 1A The high capacity type includes an identification groove 30 positioned on the left side and an identification groove 30A positioned on the right side. The battery 1 The medium-capacity type includes the identification grooves 30 and 30 which are positioned spaced apart on the left and right sides. The battery 1B The low-capacity type includes an identification groove 30 positioned on the left side.

The low power camera does not include a protruding identification portion in the battery mounting unit, and accordingly, there are no portions to be inserted in the identification grooves 30 and 30A.

Accordingly, in the battery mounting unit of the low power camera, any of the batteries can be used 1 , the battery 1A and the battery 1B it will be identified that any of the battery 1 , the battery 1A and the battery 1B a battery that is suitable for the low power camera. The medium-power camera includes the protruding identification portion 90C positioned in the battery mounting unit on the right side, and the protruding identification portion 90C can be inserted into any of the first identification part 31 of the identification groove 30 and the first identification part 31A of the identification groove 30A. The protruding identification portion 90C becomes the first identification part 31 of the identification groove 30 located on the right side of the battery 1 is positioned and inserted into the first identification part 31A of the identification groove 30A located on the right side of the battery 1A is positioned, introduced. Because no identification groove on the right side of the battery 1B is formed, on the other hand, it comes to a disability between the protruding identification portion 90C and the battery 1B ,

Accordingly, in the battery mounting unit of the medium power camera, each of the battery 1A and the battery is accordingly 1 is fastened, the battery 1B is not fastened. Thus it is identified that any of the battery 1A and the battery 1 a battery that is suitable for the medium power camera, and it identifies the battery 1B a battery that is not suitable for the medium power camera.

The high-power camera includes the protruding identification portion 90B positioned on the right side of the battery mounting unit, and the protruding identification portion 90B can be inserted into the first identification part 31A of the identification groove 30A. The protruding identification portion 90B is inserted into the first identification part 31A of the identification groove 30A located on the right side of the battery 1A is positioned, introduced. Since the protruding identification portion 90B in the first Identification part 31 of the identification groove 30, which is on the right side of the battery 1 is positioned, but can only be inserted to the middle, the electrode connection 95 with the connection terminal 35 of the connector 33 the battery 1 not connected. As on the right side of the battery 1B Moreover, if no identification groove is formed, there is an obstruction between the protruding identification portion 90B and the battery 1B , Accordingly, in the battery mounting unit of the high power camera, the battery 1A is fastened, are the battery 1 and the battery 1B can not be fastened. Thus it is identified that the battery 1A a battery that is suitable for the high power camera, and it identifies the battery 1 and the battery 1B Batteries are not usable for the high power camera.

The charger 80 includes a protruding identification portion 90 positioned on the left side of the battery mounting unit 83, and the protruding identification portion 90 can be inserted into the identification groove 30. The protruding identification portion 90 is inserted into the identification groove 30, that on the left side of each of the battery 1 , the battery 1A and the battery 1B is positioned.

In the battery mounting unit 83 of the charger 80 is therefore any of the battery 1 , the battery 1A and the battery 1B attachable, and it is identified that any of the battery 1 , the battery 1A in the battery 1B a battery is responsible for the charger 80 is usable.

In addition, although in the above-mentioned description an example relating to the identification of a battery using a difference in the charging capacity has been set forth, the identification using the identification groove 30 and the like is not limited to the identification using a difference in charging capacity. but it may be applied, for example, to an identification using any other difference, such as a difference between a chargeable type and a non-chargeable type or a difference in charging speed or the like. In the above description, although an example has been set forth for the identification groove 30 configured by two sections having the first identification part 31 and the second identification parts 32 having different lengths from each other, the identification groove 30 may be separated from each other by three or more identification parts be configured in different lengths.

As described above, is in the battery 1 (the batteries 1A and 1B ) the identification groove 30 used in the housing for identifying a connection device 2 formed, and in the Identifikationsnut 30 a plurality of identification parts are formed with mutually different lengths continuously.

Thus, since the plurality of identification parts having portions different from each other are not provided, the size of the identification groove 30 in a direction in which the identification parts are continuous is the size obtained by adding the sizes of the plurality of identification parts, and the size of the battery 1 can be downsized while ensuring a high degree of distinctness.

In addition, since the first identification part 31 and the second identification parts 32 are formed as identification parts, the size of the identification groove 30 in a direction in which the identification parts are continuous is a size obtained by adding the sizes of the first identification part 31 and the second identification parts 32 , and the size of the battery 1 can be downsized while ensuring a high degree of distinctness.

Further, in the identification groove 30, since a plurality of identification parts are formed continuously in the width direction, the size of the widthwise identification groove 30 is a size obtained by adding the sizes of the plural identification parts. Thus, the size of the battery 1 in the width direction, be smaller than that in a case where the plurality of identification grooves are formed spaced apart in the width direction while the differentiability is improved. Moreover, the widths of the plural identification parts are sequentially smaller from the smallest to the largest length. In the first identification part 31 and the second identification parts 32, for example, the width of the second identification parts 32 having a smaller length is configured smaller than the width of the first identification part 31 having a greater length.

Accordingly, the width of the identification groove 30 in the width direction is smaller than a width obtained by adding the widths in a case where identification parts having the same width are formed. Therefore, the size of the battery 1 in the width direction, while the distinctness is improved.

In addition, since the two identification grooves 30 and 30 are spaced apart from each other in the width direction, by using the two identification grooves 30 and 30 a connection device can be identified, and accordingly, the number of connection device types that can be identified can be increased.

In such a case, the shapes or sizes of the two identification grooves 30 and 30 may be further formed so as to be different from each other.

Moreover, in the identification groove 30, the first identification part 31 and the second identification parts 32 may be formed in mutually different shapes (see FIG 55 ). For example, in the identification groove 30, the second identification parts 32 may be formed in a space having an approximately triangular prism shape. By forming the identification groove 30 in such a shape, a portion of the region of the second identification parts 32 in the lower inner surface 30a of the identification groove 30 is formed as an inclined surface 32c. The inclined surface 32c is approaching the side surface positioned on an opposite side of the first identifying part 31 and passing through in the horizontal direction 13 in the direction of the lower end face 12 inclined.

The identification groove 30 is a portion close to the first guided groove 22 is formed, and by forming the identification groove 30 in such a shape, the thickness (width) of a portion between the first guided groove 22 of the housing 2 and the identification groove 30 are enlarged, and the peripheral portion of the first guided groove 22 can be strengthened.

Further, although in the above description, the identification groove 30 has been exemplified in which the first identification part 31 and the second identification parts 32 having different lengths are widthwise continuous, an identification groove 30X may be formed instead of the identification groove 30 (see FIG 56 ). The identification groove 30X has a configuration in which the first identification part 31X and the second identification parts 32X having different sizes in the vertical direction (depth direction) are continuous, and for example, the length of the first identification part 31X is larger than that of the second identification parts 32X, and the first identification part 31 is formed from the lower side of the second identification parts 32.

In addition, like the identification groove 30, the identification groove 30X may be configured by three or more identification parts having different lengths from each other.

In this way, by forming a plurality of identification parts that are continuous in the depth direction, the size of the identification groove 30X in the depth direction is a size obtained by adding the sizes of the plurality of identification parts. Thus, the size of the battery 1 in the depth direction (vertical direction) may be smaller than that in a case where the plurality of identification grooves are formed spaced apart in the depth direction while the differentiability is improved. The depths of the plural identification parts of the identification groove 30X can be made smaller from the shortest one to the largest length one after the other.

By thus configuring the identification groove 30X, the size of the identification groove 30X in the depth direction becomes smaller than a depth obtained by adding the depths in a case where identification parts having the same depth are formed. Therefore, the size of the battery 1 in the depth direction while improving distinctness.

<Modified example>

The following are modified examples for each section of the battery 1 described (see 57 to 59 ).

A first modified example is a modified example of the concave-part-forming surface (see FIG 57 and 58 ). A concave-part-forming surface 29A includes wall portions 29d and 29d according to the first modified example. The wall portions 29d and 29d are formed by first inclined surfaces 40 and 40 extending from the base portion 29a, middle surfaces 41 and 41 extending from the first inclined surfaces 40 and 40, and second inclined surfaces 42 and 42 extending from the middle surfaces 41 and 41 go out, formed.

The first inclined surfaces 40 and 40 extend from the front end of the base portion 29a and are inclined in the horizontal direction to the front side so as to extend in spaced-apart directions. The middle surfaces 41 and 41 are formed as surfaces extending from the front ends of the first inclined surfaces 40 and 40 and face toward the front side. The second inclined surfaces 42 and 42 extend from the outer ends of the middle surfaces 41 and 41 in the horizontal direction and are inclined in the horizontal direction to the front side so as to extend in spaced-apart directions. The inclination angle of the first inclined surface 40 with respect to the middle surface 41 is larger than the inclination angle of the second inclined surface 42 with respect to the middle surface 41. The inclination angle of the first inclined surface 40 with respect to the average surface However, 41 may be configured to be smaller than the inclination angle of the second inclined surface 42 with respect to the middle surface 41, or may be equal to the inclination angle of the second inclined surface 42 with respect to the middle surface 41. In addition, the width of the first inclined surface 40 in the direction of inclination is greater than the width of the second inclined surface 42 in the direction of inclination. However, the width of the first inclined surface 40 in the tilting direction may be configured to be smaller than the width of the second inclined surface 42 in the inclining direction, or may be equal to the width of the second inclined surface 42 in the inclining direction.

By forming the concave-part-forming surface 29A having the above-described wall portions 29d and 29d, the front-rearward depth of one of the rear-side of the wall portions 29d and 29d in the casing becomes 2 arranged portion increases, reducing the strength of the housing 2 can be improved.

A second modified example is a modified example of the connector (see 59 ). A connector 33A According to the second modified example, a receptacle 34 formed using a non-conductive material includes connection terminals 35 . 35 and 35 , which are formed using a conductive material. Although in the receptacle 34 Anschlußanordnungsnuten 36, 36 and 36 are formed, in which the connection terminals 35 . 35 and 35 are arranged, but there are no positioning grooves 37 and 37 are formed.

In each of the terminal arrangement grooves 36, 36 and 36 are connection terminals 35 . 35 and 35 arranged, which serve as a positive electrode terminal, negative electrode terminal or information terminals. In addition, in the connector 33A two terminal arrangement grooves 36 and 36 or four terminal arrangement grooves 36, 36, ... may be formed. In a case where two terminal arrangement grooves 36 and 36 in the connector 33A are formed, a positive electrode terminal and a negative electrode terminal are disposed in the two terminal arrangement grooves 36 and 36, respectively. In a case where four terminal arranging grooves 36, 36, ... in the connector 33A are formed, a positive electrode terminal, a negative electrode terminal, an information terminal and a communication terminal, respectively, are formed in the four terminal arrangement grooves 36, 36,.

In a case where the connector 33A are used, the positioning grooves 37 and 37 on both the left and on the right side of the connector 33A in the housing 2 educated.

By using the above-described connector 33A The widths of arranged on both sides of the concave arrangement part 27 sections in the housing 2 in the horizontal direction are increased, whereby the strength of the housing 2 can be improved.

<Configuration of another battery>

It becomes the configuration of a battery 1C coming from the battery 1 is different, described (see 60 and 61 ).

In addition, the battery described below differs 1C from the battery described above 1 only in that there is no connector, and the configurations of the other sections and a positional relationship between the sections and the sizes of the sections are similar to those of battery 1 , Thus, in the following, only sections that are different from those of battery will be described in detail 1 and it will be the same reference numbers, the similar sections of battery 1 are assigned to the other sections, and a description thereof will not be set forth.

In the front end portion of a lower part 21, a concave part 27C is formed (see FIG 60 ). The concave part 27C is formed in the horizontal direction approximately at the center and is open to the front side and the lower side.

The concave part 27C is formed by a concave-part-forming surface 29C educated. The concave part forming surface 29C is formed by a base portion 29e, wall portions 29b and 29b and a central portion 29c.

The base portion 29e is formed in a state facing the front side. The wall portions 29b and 29b extend from both ends, the left and right ends, of the base portion 29e and are inclined to the front side as horizontally spaced surfaces. The middle portion 29c is formed facing the lower side between the lower edges of the wall portions 29b and 29b.

In a from the rear side of the concave part 27C in the housing 2C outgoing section, terminal arrangement grooves 36C, 36C and 36C are formed spaced apart from each other on the left and right sides. An opening of the front side of the terminal arrangement groove 36C open to the lower side and the front side is formed in the base portion 29e. The connection connections 35 . 35 and 35 be through the case 2C held in a state in which at least parts thereof are arranged in the terminal arrangement grooves 36C, 36C and 36C. In the battery 1C If no connector is disposed, but the connection terminals 35, 35 and 35 are configured as terminal portions.

In the case 2C For example, front side and lower side positioning grooves 37C and 37C are horizontally formed on the outside of the terminal arrangement grooves 36C, 36C and 36C. In the case 2C That is, portions between the terminal arrangement grooves 36C, 36C and 36C are arranged as terminal separating ribs 2b and 2b, and portions between the terminal arrangement grooves 36C and 36C and the positioning grooves 37C and 37C in the housing 2C are arranged as Zwischenutrutrippen 2c and 2c. The horizontal width of the terminal separating rib 2b is configured to be larger than the horizontal width of the intermediate nip 2c to make contact between the connecting terminals 35 . 35 and 35 to prevent. Although in the above description an example has been presented in which the positioning grooves 37C and 37C are formed as points outgoing from the concave part 27C, the positioning grooves 37C and 37C may be concave on both sides, the left and the right side Part 27C in the housing 2C be educated (see 61 ).

In addition, in the battery 1C similar to the battery 1 two terminal arrangement grooves 36C and 36C or four terminal arrangement grooves 36C, 36C, ... may be formed.

Because, as described above, in the battery 1C no connector is disposed and the terminal arrangement groove 36C and the positioning groove 37C in the housing 2C are formed, the manufacturing cost can be reduced according to the simplification of the structure, and the number of components can be reduced.
