The battery contact 12T of the contact member 12P mounted on the mounting board 42 protrudes into the battery housing 41 through the terminal opening 41A.

A support boss 41 </ b> B and a fixing boss 41 </ b> C protrude from the upper surface of the upper surface plate 41 </ b> U of the battery storage unit 41. The support boss 41 </ b> B and the fixing boss 41 </ b> C support the mounting substrate 42 and are coupled to the upper surface cover 23.
The support boss 41B has an axial shape with a predetermined diameter, has a predetermined height from the upper surface of the upper surface plate 41U, and is erected in the vicinity of the center of the back side long side of the upper surface plate 41U.

  The fixing boss 41C is formed in a two-stage shape having a small-diameter fitting shaft portion 41Cb projecting from the tip of the support shaft portion 41Ca and having a step portion 41Cd. The fixing bosses 41C are provided upright in the vicinity of both ends in the left-right direction of the long side of the front surface of the upper surface plate 41U.

The height of the step 41Cd from the upper surface plate 41U in the fixing boss 41C is equal to the height of the support boss 41B. Further, the height from the step portion 41Cd of the fixing boss 41C to the tip surface (the height of the fitting shaft portion 41Cb) is slightly smaller than the thickness of the mounting substrate 42.
A screw insertion hole is formed at the center of the fixing boss 41C so as to penetrate vertically from the inner surface side of the upper surface plate 41U.

The mounting substrate 42 is a rectangular plate having a predetermined thickness and substantially corresponding to the upper surface plate 41 </ b> U in the battery storage unit 41. A release switch 12R is mounted on the upper surface of the mounting substrate 42, and a contact member 12P having a battery contact 12T is mounted on the lower surface.
A mounting hole 42B is formed in the mounting substrate 42 at a position corresponding to the support boss 41B in the battery housing portion 41, and a positioning fitting hole 42C is formed at a position corresponding to the fixing boss 41C. The positioning fitting hole 42C is set to a predetermined fitting tolerance in which the fitting shaft portion 41Cb of the fixing boss 41C is fitted without rattling.

As described above, the release switch 12R is a switch that switches in two steps according to the pressing stroke, and commands focusing and photometry by half-pressing, and shooting by full-pressing.
The contact member 12 </ b> P includes a plurality of battery contacts 12 </ b> T, and is disposed closer to the side of the back side of the mounting substrate 42 on the negative side of the X axis.
The battery contact 12T in the contact member 12P is formed by a metal having conductivity and spring property so as to be elastically deformable in the Y-axis direction (direction orthogonal to the plate surface of the mounting substrate 42) in the drawing. Although not limited to this, five battery contacts 12T are arranged in parallel in the X-axis direction at a predetermined interval in this embodiment.

  As shown in FIG. 6, in the mounting substrate 42, the positioning fitting hole 42 </ b> C is fitted to the fitting shaft portion 41 </ b> Cb of the fixing boss 41 </ b> C in the battery housing portion 41. Then, the set screw 44 is inserted into the mounting hole 42 </ b> B from the upper side and is screwed into the support boss 41 </ b> B of the battery storage unit 41 to be fixed to the battery storage unit 41. Thereby, the battery box assembly 40 is configured.

When mounting to the battery housing 41, the mounting board 42 fits the positioning fitting hole 42C into the fitting shaft 41Cb of the fixing boss 41C, and screws the set screw 44 into the support boss 41B to engage in the Y-axis direction. It is fixed so as not to leave. At this time, the lower surface of the mounting substrate 42 is supported by the upper portion of the step 41Cd of the fixing boss 41C and the support boss 41B, and the mounting substrate is kept parallel to prevent deformation.
At this time, the battery contact 12T in the contact member 12P mounted on the mounting substrate 42 protrudes from the terminal opening 41A of the upper surface plate 41U in the battery storage unit 41 to the inside of the battery storage unit 41 by a predetermined amount.

  The battery box assembly 40 configured as described above is fitted into the opening side of the frame 30. As shown in FIG. 3, the engaging claws 41 </ b> P of the side plate 41 </ b> S of the battery storage unit 41 engage with the guide grooves 33 of the side plate 32 of the frame 30 and are attached to the frame 30. At this time, the engaging claw 41 is guided by the guide groove 33 and can move by the length of the guide groove 33 in the vertical direction (Y direction). That is, the battery storage part 41 (battery box assembly 40) is movable along the guide groove 33 by the length in the vertical direction (Y direction) of the guide groove 33 with respect to the frame 30.

Further, as shown in FIG. 2, the fixing screw 45 inserted into the screw insertion hole of the fixing boss 41 </ b> C from the inside of the battery storage portion 41 is screwed into the second protrusion 23 </ b> B of the upper surface cover 23 to be in the upper surface cover. Fastened to 23. Thereby, the battery box assembly 40 is coupled to the upper surface cover 23 via the mounting substrate 42.
As described above, since the height of the fitting shaft portion 41Cb in the fixing boss 41C is set slightly smaller than the thickness of the mounting substrate 42, the mounting substrate 42 is connected to the stepped portion 41Cd of the fixing boss 41C and the upper surface. It is sandwiched between the cover 23 (second protrusion 23B) and the upper surface thereof is pressed against the second protrusion 23B of the upper surface cover 23.

  Note that the fitting shaft portion 41 </ b> Cb of the fixing boss 41 </ b> C may protrude from the mounting substrate 42, and the protruding portion may be fitted into the recess formed in the second protrusion 23 </ b> B of the upper surface cover 23. Also in this configuration, the battery box assembly 40 can be positioned in the horizontal direction (X-axis and Z-axis directions) with respect to the upper surface cover 23.

  As described above, the battery box assembly 40 is supported by the frame 30 and fixed to the upper surface cover 23. As a result, the back plate 31 of the frame 30 is positioned on the back side where the battery storage unit 41 is opened, and the battery storage unit 41 and the frame 30 form a storage space 12S that opens only on the bottom surface side. The battery 14 can be inserted into and removed from the housing space 12S in the Y-axis direction from the lower opening.

The upper surface plate 41U in the battery housing portion 41 forms the top surface of the housing space 12S, and the battery contact 12T in the contact member 12P is inside the battery housing portion 41 (that is, inside the housing space 12S) from the terminal opening 41A. Project a predetermined amount.
The battery contact 12T abuts on the battery 14 accommodated in the battery accommodating part 41, and power supply from the battery 14 to the main body part 11 becomes possible.

Although the detailed description is omitted, the lower opening of the accommodation space 12S is covered with a swingable lid that is attached to the exterior member (the front cover 21 or the back cover 22). By opening the lid and moving the battery retainer 43 to the retracted position, the battery 14 can be inserted into and removed from the accommodation space 12S.
The battery 14 accommodated in the accommodation space 12S is regulated in position in the Y-axis direction by the battery retainer 43, and press-contacted to the battery contact 12T so as to be conductive. Since the battery 14 is pressed against the battery contact 12T, the mounting substrate 42 is pressed upward (Y-axis plus side) via the battery contact 12T. However, the deformation of the mounting substrate 42 by this pressing force is restricted by the third protrusion 23C of the upper surface cover 23 located on the upper surface thereof. Thereby, the fall of the press-contact force of the battery contact 12T by the mounting substrate 42 escaping, the contact failure resulting from it, etc. can be prevented.

As described above, the battery chamber 12 is configured such that the battery box assembly 40 is supported by the frame 30 and is fixed to the upper surface cover 23.
As described above, the mounting substrate 42 is sandwiched between the step portion 41Cd of the fixing boss 41C and the upper surface cover 23 (second projection portion 23B), and the upper surface thereof is in contact with the second projection portion 23B of the upper surface cover 23. It is pressed and fixed.

  Thereby, the position of the upper surface of the mounting substrate 42 in the Y-axis direction with respect to the upper surface cover 23 can be defined with high accuracy. As a result, the relative position in the Y-axis direction between the release switch 12R mounted on the top surface of the mounting substrate 42 and the release button 13 mounted on the top cover 23 can be set with high accuracy, and the release switch 12R is operated for switching. The pressing stroke of the release button 13 can be made constant with high accuracy.

  Further, the lower surface of the mounting substrate 42 is pressed against the step portion 41Cd of the fixing boss 41C, and the position in the Y-axis direction with respect to the battery housing portion 41 is determined. Thereby, the protrusion amount to the inside of the battery accommodating part 41 of the battery contact 12T in the contact member 12P mounted on the lower surface of the mounting substrate 42 can be specified with high accuracy. For this reason, the tolerance | permissible_range of the elastic deformation amount for press-contacting to the battery 14 can be made small, and the contact member 12P (battery contact 12T) can be comprised small. As a result, the camera 1 as a whole can be reduced in size.

That is, in this configuration, the release switch 12R and the contact member 12P are mounted on the front and back of one mounting substrate 42, and both of them can be functionally arranged with high accuracy.
Further, the positional accuracy in the Y-axis direction of the battery storage portion 41 in the battery box assembly 40 with respect to the upper surface cover 23 is high, and accordingly, other exterior covers 20 (the front cover 21 and the rear cover 22 provided by being connected to the upper surface cover 23). Etc.) and relative position accuracy can be increased.

Next, an assembly process of the battery chamber 12 as described above will be described.
As for the assembly of the battery chamber 12, first, as shown in FIG. 6, the mounting substrate 42 is mounted on the battery storage 41 to constitute the battery box assembly 40 shown in FIG. That is, the positioning fitting hole 42 </ b> C of the mounting substrate 42 is fitted to the fitting shaft portion 41 </ b> Cb of the fixing boss 41 </ b> C in the battery housing portion 41, and the set screw 44 inserted from above the mounting hole 42 </ b> B is inserted into the battery housing portion 41. The mounting board 42 is fixed to the battery housing 41 by screwing into the support boss 41B.

Next, as shown in FIG. 7, the battery box assembly 40 is attached to the frame 30 attached to the main body 11.
That is, the battery housing part 41 is fitted to the opening side (front side) of the frame 30 with the opening side facing the back side, and the engaging claws 41P of the side plate 41S of the battery housing part 41 are connected to the side plate 32 of the frame 30. Engage with the guide groove 33.
As described above, the engagement claw 41P of the battery storage unit 41 engages with the guide groove 33 of the frame 30 so as to be movable in the Y-axis direction by a predetermined amount without rattling in the Z-axis direction. Thereby, the battery storage unit 41 (battery box assembly 40) is mounted on the frame 30 so as to be movable by a predetermined amount in the Y-axis direction with the position in the Z-axis direction determined.
In this state, a connector connection operation for connecting the mounting substrate 42 and the main body 11 is performed.

  Then, the fixing screw 45 inserted into the screw insertion hole of the fixing boss 41 </ b> C from the inside of the battery housing part 41 in the battery box assembly 40 is screwed into the second protrusion 23 </ b> B of the upper surface cover 23 to sandwich the mounting substrate 42. Then, the fixing boss 41C (battery storage portion 41) is fastened to the upper surface cover 23. At the time of fastening, the battery box assembly 40 can move by a predetermined amount with respect to the frame 30 in the Y-axis direction. It can be positioned and mounted well. As a result, the battery chamber 12 is assembled as shown in FIGS.

The mounting substrate 42 is sandwiched and fixed between the second protrusion 23 </ b> B of the upper surface cover 23 and the upper surface plate 41 </ b> U of the battery storage portion 41.
Thereby, the position of the upper surface of the mounting substrate 42 in the Y-axis direction with respect to the upper surface cover 23 is defined with high accuracy. As a result, the relative position in the Y-axis direction between the release switch 12R mounted on the top surface of the mounting substrate 42 and the release button 13 mounted on the top cover 23 can be set with high accuracy, and the release switch 12R is operated for switching. The pressing stroke of the release button 13 can be made constant with high accuracy.

  Further, the position of the lower surface of the mounting substrate 42 in the Y-axis direction with respect to the battery housing portion 41 is defined by the step portion 41Cd of the fixing boss 41C. Thereby, the protrusion amount to the inside of the battery accommodating part 41 of the battery contact 12T in the contact member 12P mounted on the lower surface of the mounting substrate 42 can be specified with high accuracy. For this reason, the tolerance | permissible_range of the elastic deformation amount for press-contacting to the battery 14 of the battery contact 12T can be made small, and the contact member 12P can be formed small. As a result, the camera 1 as a whole can be reduced in size.

(2) The frame 30 constituting the battery chamber 12 is formed of a material having high thermal conductivity such as an aluminum alloy. The frame 30 is coupled to the main body 11 so as to be able to conduct heat with respect to the main body 11. A back cover 22 is connected to the frame 30 through a heat transfer connecting portion 22A so as to be able to conduct heat. Thereby, the back cover 22 can be functioned as a heat radiating member, and it can thermally radiate efficiently.

(3) The battery housing part 41 in the battery box assembly 40 is engaged with the engagement claw 41P so as to be movable in the Y-axis direction by a predetermined amount in the guide groove 33 of the frame 30. Thereby, the battery box assembly 40 can be positioned and attached to the upper surface cover 23 with high accuracy.
