Description

  The present invention relates to a camera and a portable small electronic device in which a strap can be attached.

  2. Description of the Related Art Conventionally, a camera, a mobile phone, a PDA (Personal Digital Assistant), a portable music player, and the like are known as portable small electronic devices. Some of such portable small electronic devices have improved portability by providing a strap attaching portion for attaching the strap to the case.

  Such strap attachment parts include a strap attachment hole that allows a strap to be inserted in a protrusion partly protruding from a case of a portable small electronic device (for example, a patent) Reference 1). In Patent Document 1, a camera is exemplified as a portable small electronic device. In this case, since the strap attaching hole is formed in the protruding portion, the strap can be easily inserted into the strap attaching hole, but the strap attaching portion partially protrudes from the contour shape of the case. For this reason, when the camera is gripped for taking a picture, the strap attaching portion hits the palm. When the protrusion hits the palm in this way, the user feels uncomfortable.

  In addition, it is considered that the strap attachment portion is provided with a strap attachment hole formed so that both ends are opened on the same wall surface forming a part of the contour shape of the case so as to communicate with the inside of the wall portion. In this case, since the strap attachment portion does not protrude with respect to the contour shape of the case, for example, even if the camera is gripped for shooting, the strap attachment portion can be prevented from hitting the palm as a protrusion, Since the entrance and exit of the strap attachment hole are located on the same plane, it is difficult to insert the strap through the strap attachment hole.

Therefore, in the strap attachment part, at the corner where two different surfaces of the case cross each other, one end opens on one wall surface and the other end opens on the other wall surface, and both openings communicate with each other on the inner side of the main body case. Some strap attachment holes are formed so as to do so (for example, see Patent Document 2). Patent Document 2 exemplifies a mobile phone with a camera among portable small electronic devices. In this case, since the strap attaching portion does not protrude from the contour shape of the case, the strap attaching portion can be prevented from hitting the palm as a protrusion when the camera-equipped mobile phone is gripped. Since the entrance and the exit of this are located on different wall surfaces at the corners of the case, the strap can be easily inserted into the strap attachment hole.

The non-slip portion 22 is formed by arranging a large number of small protrusions in a rectangular shape within a predetermined region of the upper right half of the rear wall 16 and functions as a non-slip of the addressed finger.

  As shown in FIGS. 3 and 4, the upper wall surface 17, the bottom wall surface 18, the left wall surface 19, and the right wall surface 20 are formed by cooperation of a front case 12, an intermediate case 13, and a rear case 14 connected in order from the front. is doing. The upper wall surface 17 is provided with a release button 25 that constitutes a part of a camera mechanism (not shown). In this embodiment, the release button 25 is arranged on the upper wall surface 17 so as to be biased to the right side.

  In the camera 10, various functions can be selected by appropriately operating various operation buttons 24, and a subject can be photographed while an image is displayed on the liquid crystal monitor 23 by pressing the release button 25.

  In the camera 10 according to the present invention, a strap attachment portion 40 is provided on the right side portion 20, and the structure of the strap attachment portion 40 is different from that of a conventional camera. This will be described below.

  In the camera 10, the intermediate case 13 extends to the right side from the front case 12 and the rear case 14, and a projecting body 41 is formed by a portion extending from the front case 12 and the rear case 14. Yes. In other words, as shown in FIG. 5, the right side portion of the mechanism accommodating space 26 is the right side wall 27 (corresponding to the deflection side wall in claim 9, corresponding to the defined side wall in claim 9), that is, the front side in the front case 12. Since the right side wall portion 12a, the right side partition wall portion 13a in the intermediate case 13 and the rear right side wall portion 14a in the rear case 14 are defined, the right side wall portion 13a (mechanism housing space) described above is formed in the intermediate case 13. 26), a portion extending to the right side (the outer right side in the case 11) corresponds to the protrusion body 41. For this reason, the protrusion 41 extends rightward from the front right wall surface 12b formed by the front right wall portion 12a in the front case 12 and the rear right wall surface 14b formed by the rear right wall portion 14a in the rear case 14. ing.

  When viewed in a cross section perpendicular to the vertical direction (see FIG. 5), the ridge body 41 has a wall surface 42 before attachment and a palm harmony wall surface 43 continuous thereto, and the palm harmony wall surface 43 and the wall surface 42 before attachment. A continuous portion (ridge line) 44 is rounded (chamfered) into a curved surface.

  The wall surface 42 before attachment extends from the rear end position 12c of the front right wall surface 12b of the front case 12 to the right side in the left-right direction and extends to the right side when viewed in a cross section perpendicular to the vertical direction. The palm harmony wall surface 43 extends in a direction inclined with respect to the front-rear direction so as to go to the left side from the continuous portion 44 toward the rear side so as to continue to the wall surface 42 before attachment on the rear side of the wall surface 42 before attachment. The rear case 14 reaches the front end position 14c of the rear right wall surface 14b. Therefore, the pre-attachment wall surface 42 is a surface facing forward in the ridge body 41, the palm harmony wall surface 43 is a surface facing rearward in the ridge body 41, and the pre-attachment wall surface 42 and the palm harmony wall surface 43 are in the front-rear direction. It will be located on the same line seen in.

  Further, the pre-attachment wall surface 42 and the palm harmony wall surface 43 (the ridge body 41) are configured to extend in the vertical direction with a substantially constant width dimension. A continuous portion 44 between the palm harmony wall surface 43 and the pre-attachment wall surface 42 becomes a contour of the right end portion of the case 11 (hereinafter referred to as a right contour ridge line 44), and the right contour ridge line 44 is formed on the front right side formed by the front case 12. The wall surface 12b and the rear case 14 extend in the vertical direction substantially parallel to the rear right wall surface 14b. For this reason, when the camera 10 is viewed from the front, as shown in FIG. 1, the protrusion 41 (the strap attachment portion 40 as will be described later) extends in the vertical direction with a constant width dimension at the left end, When the camera 10 is viewed from the rear from the front, as shown in FIG. 2, the protrusion 41 (a strap attachment portion 40 as will be described later) extends in the vertical direction with a constant width dimension at the right end.

  Here, the palm harmony wall surface 43 extending with a substantially constant width dimension has a predetermined width dimension (a length dimension as viewed in a direction perpendicular to the spanning direction described later). The predetermined width dimension of the palm harmony wall surface 43 is a general size in a scene (see FIG. 9) in which the right end of the camera 10 (case 11) is held with a palm so as to be held in the palm, as will be described later. It refers to the width dimension (length dimension) that makes the user feel that the palm of the dimension is in contact with the surface rather than making it feel at the point or line. Therefore, the width dimension of the palm harmony wall surface 43 is set in consideration of a general palm size dimension, a size dimension of the entire case 11, a dimension dimension of the right side wall surface 20 with respect to the case 11, and the like. .

  Further, the palm harmony wall surface 43 has a vertical direction while smoothly continuing a portion (13b) formed by the intermediate case 13 in the upper wall surface 17 and a portion (13b) formed by the intermediate case 13 in the bottom wall surface 18. It is formed so as to bridge over. In other words, the protrusions 41 are angled in a plane perpendicular to the vertical direction with respect to the extending direction (left-right direction) of the intermediate upper wall surface 13b of the intermediate case 13 forming a part of the upper wall surface 17 of the case 11. The positional relationship between the middle upper wall surface 13b and the palm harmony wall surface 43 is set so as to form a ridge line (hereinafter referred to as the palm harmony wall upper end portion 43a) along the intersecting line, and the bottom of the case 11 With respect to the extending direction (left-right direction) of the intermediate bottom wall surface 13c of the intermediate case 13 forming a part of the wall surface 18, the line is parallel to the palm harmony wall lower end 43b at a height position equal to the intermediate bottom wall surface 13c. The positional relationship between the intermediate bottom wall surface 13c and the palm harmony wall surface 43 is set so as to form a ridge line (hereinafter referred to as a palm harmony wall lower end portion 43b). For this reason, the intermediate case 13 is a belt-like surface that is smoothly continuous and has a rectangular shape by an intermediate left side surface 13d, an intermediate upper wall surface 13b, a palm harmony wall surface 43, and an intermediate bottom wall surface 13c that form part of the left side surface of the case 11. A ring will be drawn.

  Furthermore, as shown in FIG. 5, the palm harmony wall surface 43 is set such that the angle θ with the rear wall surface 16 in the case 11 formed by the rear case 14 becomes an obtuse angle. When the case 11 is gripped with the right hand so that the strap attaching portion 40 is covered with a palm and the front wall surface 15 and the rear wall surface 16 of the case 11 are sandwiched between the angle θ, In a state in which the thumb is placed on the stop portion 22 and the case 11 is pressed from the front wall surface 15 side to the thumb side (see FIG. 9), it cooperates with the rear wall surface 16 so as to harmonize with the palm near the base of the thumb. An angle with the rear wall surface 16 at a position close to the rear wall surface 16 is set to an obtuse angle. Here, in order to harmonize, a palm having a general size is not felt to be in contact with a point or a line, and the pressing force is dispersed on a smooth surface, and a wide area of the palm is distributed. A state where the surface abuts on the surface.

  In the camera 10 of the present embodiment, the palm harmony wall surface 43 is curved so as to follow a curved surface centered on the virtual center R when viewed in a cross section perpendicular to the vertical direction. In addition, the rear right wall surface 14 b of the rear case 14 adjacent to the palm harmony wall surface 43 is curved so as to follow a curved surface having a radius smaller than that of the palm harmony wall surface 43 with the virtual center R as the center. And the location which adjoins the back right side wall surface 14b of the back case 14 among the palm harmony wall surfaces 43 of the strap attaching part 40 is made into a curved surface by the corner being dropped (beveled). Further, in the rear case 14, a corner from the rear right wall surface 14 b to the rear wall surface 16 is dropped (chamfered) to be a curved surface.

  Further, in the camera 10 of the present embodiment, the front right side wall surface 12b of the front case 12 is inclined with respect to the front-rear direction from the rear end position 12c adjacent to the front wall surface 42 so as to move to the left side toward the front side. It is supposed to be configured. For this reason, the right contour ridgeline 44 of the ridge 41 (the ridgeline between the pre-attachment wall surface 42 and the palm harmony wall surface 43) is located at the right end of the case 11 when viewed in the left-right direction, and the palm harmony wall surface 43 and A virtual side surface I (a curved surface with the virtual center R as the center) formed by extending it is positioned at the outermost contour on the right side of the case 11. In the camera 10 of the present embodiment, a strap insertion hole 45, a terminal storage space 50, and a terminal shielding lid 51 capable of shielding the terminal storage space 50 are provided on the projecting body 41, and the strap attachment portion 40 is provided. It is configured.

  As shown in FIG. 6, the strap insertion hole 45 communicates with a rear end opening 46 whose one end opens the palm harmony wall surface 43 and a front end opening 47 whose other end opens the front wall surface 42. It is formed through the ridge body 41. In the present embodiment, the palm harmony wall surface 43 is provided with a first rear end opening portion 46a and a second rear end opening portion 46b positioned below independently of the first rear end opening portion 46a. Yes. The first rear end opening portion 46a is a substantially central position of the palm harmony wall surface 43 as viewed in the width direction (a direction along a plane perpendicular to the vertical direction), and the palm harmony wall surface along the vertical direction from the palm harmony wall upper end portion 43a. This is a long hole extending to the vicinity of the intermediate position at 43. The second rear end opening portion 46b is formed so as to be in series with the first rear end opening portion 46a in the vertical direction, and has a length dimension shorter than that of the first rear end opening portion 46a.

  Further, in the present embodiment, the front wall surface 42 has a first front end opening portion 47a corresponding to the first rear end opening portion 46a and a second rear end opening portion 46b corresponding to the second rear end opening portion 46b. A front end opening portion 47b is provided. The first front end opening portion 47 a and the second front end opening portion 47 b are configured to be adjacent to the rear end position 12 c of the front right wall surface 12 b of the front case 12. For this reason, the width dimension seen in the left-right direction of the strap attachment portion 40, that is, the amount (length dimension) by which the intermediate case 13 extends to the right side of the front case 12 and the rear case 14 to form the protrusions 41. Can be minimized.

  Thus, in the camera 10, as the strap insertion hole 45, the first strap insertion hole 45a which is a through hole extending from the first rear end opening portion 46a to the first front end opening portion 47a, and the first strap insertion hole 45a.

By the first strap insertion hole 45a and the second strap insertion hole 45b, columnar portions 48, 48 are formed in the vicinity of the palm harmony wall upper end portion 43a of the protrusion 41, and the straps are formed in the columnar portions 48, 48. It will be wound as appropriate. For this reason, the partition wall part 49 which divides the 1st strap insertion hole 45a and the 2nd strap insertion hole 45b functions also as a rib for ensuring the intensity | strength of the columnar parts 48 and 48. FIG. Therefore, when the strength of the columnar portions 48, 48 can be sufficiently secured, the rear end partition wall that simply partitions the first rear end opening portion 46a and the second rear end opening portion 46b instead of the partition wall portion 49. And a front end partition wall section that partitions the first front end opening portion 47a and the second front end opening portion 47b, and the four opening portions 46a, 46b, 47a, 47b communicate with each other. . A terminal storage space 50 (see FIG. 7B) and a terminal shielding lid 51 are provided below the second strap insertion hole 45b.

  As shown in FIG. 7, the terminal storage space 50 is formed by forming a protrusion 41 so as to open the palm harmony wall surface 43 in a substantially rectangular shape, and a camera mechanism (not shown) and other than the camera mechanism are formed. It contains connection terminals that allow connection with other devices. In this embodiment, as shown in FIG. 7B, in the terminal storage space 50, an AV output terminal 53 that can be connected to an AV cable terminal 52 and a USB (Universal Serial Bus) cable terminal 54 are connected. A USB terminal 55 is provided. A terminal shielding lid 51 is provided to open and close the opening 56 of the terminal storage space 50.

  In the closed state C (see FIG. 7A), the terminal shielding lid 51 can constitute a part of the palm harmony wall surface 43 and a part of the pre-attachment wall surface 42. In the present embodiment, the terminal shielding lid 51 is configured as a hinge mechanism that rotatably supports the shaft member 57 extending along the front end side in the opening 56 of the terminal storage space 50, and is in the open state O (FIG. 7). (B)) and the closed state C (see FIG. 7 (a)). Specifically, as shown in FIG. 8, the terminal shielding lid 51 includes a terminal shielding lid portion 58 that forms a part of the palm harmony wall surface 43 and can shield the opening 56 of the terminal storage space 50, and is continuous therewith. The bearing member 59 for supporting the shaft member 57 and the terminal shielding cover 58 as viewed from the bearing 59 have a fixed projecting part 60 projecting on the opposite side and rotating integrally with the bearing part 59. .

  The shaft member 57 is provided in the vicinity of the opening of the opening / closing mechanism accommodating space 62 provided adjacently on the front side of the terminal storage space 50. In the opening / closing mechanism accommodating space 62, a plate member 61 that is elastically deformable at an inner position (left side) than the shaft member 57 is provided.

  The plate member 61 is provided so that the tip of the fixed projection 60 provided on the support portion 59 rotated around the shaft member 57 crosses a circular orbit drawn along with the opening and closing of the terminal shielding cover 58 on a straight line. In addition, when the terminal shielding cover 58 is in the intermediate state M (see FIG. 8B), the position is set such that the largest deformation is caused by the contact of the fixed protrusion 60. Thus, the terminal shielding lid 51 is rotated toward the intermediate state M (see FIG. 8B) in the open state O (see FIG. 8C) and the closed state C (see FIG. 8A). Since the fixed projection 60 needs to bend and deform the plate member 61 to move, the open state O (see FIG. 8C) and the closed state C (see FIG. 8A) are caused by the elastic force of the plate member 61. )) Will be maintained.

  For example, as shown in FIG. 9, the camera 10 according to the present embodiment is sandwiched between the front wall surface 15 and the rear wall surface 16 so as to cover the strap attachment portion 40 with the palm of the right hand RH, and holds the case 11 with the right hand RH. Suppose that the left hand LH supports the left side of the case 11 and performs a shooting operation. At this time, ideally, in the configuration of the camera 10, in the right hand RH, the thumb is addressed to the non-slip portion 22, the index finger is addressed to the release button 25, and the middle finger or the like is the front wall surface 15 of the case 11 (FIG. 5). The release button 25 is pressed by the index finger in a state where the case 11 is held so as to press the case 11 from the front wall surface 15 side to the thumb side.

  When the camera 10 is gripped as shown in FIG. 9, in the camera 10, the right contour ridge line 44 (ridge line between the wall surface 42 before mounting and the palm harmony wall surface 43) of the ridge body 41 is positioned at the right end of the case 11 when viewed in the left-right direction. Since the palm harmony wall surface 43 and the virtual side surface I formed by extending it are positioned at the outermost contour in the right side portion of the case 11, the palm near the base of the thumb of the right hand RH is mainly predetermined. It will be abutted against the palm harmony wall surface 43 having a width dimension of no, and it will not abut as a protrusion that makes the strap attachment portion 40 feel uncomfortable with the palm rolled to cover the strap mounting portion 40 with the palm. .

  9, in the camera 10, the rear right wall surface 14 b of the rear case 14 has a larger curvature (small radius) than the palm harmony wall surface 43 with the same virtual center R as the palm harmony wall surface 43 as the center. ) And inward of the palm harmony wall surface 43, when the palm near the base of the thumb of the right hand RH is brought into surface contact with the palm harmony wall surface 43 having a predetermined width dimension, In the case 14, the portion from the rear right wall surface 14 b to the rear wall surface 16 does not come into contact with the palm of the right hand RH to be gripped as a protrusion that makes the user feel uncomfortable.

  Furthermore, when gripping as shown in FIG. 9, in the camera 10, the palm harmony wall surface 43 is smooth so as to draw a ring with a belt-like surface smoothly connecting the intermediate upper wall surface 13 b and the intermediate bottom wall surface 13 c of the intermediate case 13. Since it is continuously stretched up and down, in the right hand RH, it is intermediate between the index finger that presses the release button 25 and the palm near the base of the thumb that is in contact with the palm harmony wall 43. There is no contact between the upper wall surface 13b and the palm harmony wall surface 43 as a protrusion that makes the user feel uncomfortable.

  In the camera 10 of the present embodiment, the strap insertion hole 45 of the strap attachment portion 40 has a rear end opening 46 serving as one end that opens the palm harmony wall surface 43 facing rearward in the ridge 41 and a front end serving as the other end. Since the opening 47 is configured to open the pre-mounting wall surface 42 facing forward in the protrusion 41, for example, as shown in FIG. 10, the strap insertion hole 45 (first strap insertion hole 45a, second strap insertion) A strap (see symbols S and Sb) can be easily inserted through the hole 45b).

  In the camera 10, the user can appropriately select the first strap insertion hole 45a and the second strap insertion hole 45b and attach the strap S, so that it is possible to meet various requests of the user.

  In the camera 10, the strap insertion hole 45 is located on the right side (the case 11) of the right partition wall portion 13 a of the intermediate case 13 that defines a part of the right side portion of the mechanism housing space 26 for housing a camera mechanism (not shown). Since it is configured to penetrate the protrusion 41 in the outward direction as viewed from the side, the mechanism accommodating space 26 is separated from the mechanism accommodating space 26 without invading the region as the mechanism accommodating space 26, and the volume of the mechanism accommodating space 26 is increased. The strap can be easily attached without reduction. For this reason, it is suitable for a camera that has been required to be downsized while improving various functions in recent years, and thus to a portable small electronic device.

  In the camera 10, since the first strap insertion hole 45a is a long hole, even if it is a belt-like strap Sb as shown in FIG. 10, it can be easily attached.

  In the camera 10, since the first strap insertion hole 45a is a long hole, for example, as shown in FIG. 11, the strap S is attached to the first strap insertion hole 45a. By attaching to the vicinity of the lower end of the insertion hole 45a (see the strap S indicated by the alternate long and short dash line), the camera 10 is prevented from being tilted in a state of being hung from the neck or the wrist. By shifting the strap S to the uppermost end position of the strap insertion hole 45a (see the strap S indicated by the solid line), the strap S interferes with the right hand RH (see FIG. 9) operated while gripping the right end portion of the case 11. Can be prevented.

  When the camera 10 is connected to a camera mechanism (not shown) and a device other than the camera mechanism, the terminal shielding lid 51 that can open and close the opening 56 of the terminal storage space 50 is in the open state O (FIG. 7B). ) And FIG. 8 (c)), the connection of external devices to the connection terminals (in this embodiment, AV output terminal 53, USB terminal 55) (in this embodiment, AV cable terminal 52, The USB cable terminal 54) is easy.

  In the camera 10, the terminal shielding space 51 can shield the terminal storage space 50 so as to constitute a part of the palm harmony wall surface 43 in a state where a camera mechanism (not shown) and a device other than the camera mechanism are not connected. Since it is configured (see FIG. 7A), the decorativeness of the appearance is not impaired due to the provision of the terminal storage space 50.

  In the camera 10, the terminal shielding lid 51 that can open and close the opening 56 of the terminal storage space 50 is in a closed state C (FIG. 7) in a state where a camera mechanism (not shown) and a device other than the camera mechanism are not connected. Since it is fixed in (a) and FIG. 8 (a)), it is possible to prevent the terminal shielding lid 51 from opening unintentionally.

  In the camera 10, in the terminal shielding lid 51 that opens and closes the terminal storage space 50, the open state O (see FIGS. 7B and 8C) and the closed state C (FIGS. 7A and 8A). )), The mechanism that enables fixing is provided in the protrusion 41 extending outward from the mechanism housing space 26 defined by the case 11, and the case is provided to provide the mechanism. 11 does not need to be enlarged, or the mechanism is not provided in the mechanism housing space 26.

Therefore, the decorativeness of the appearance is not impaired due to the provision of the strap attaching portion 40, but rather the decorativeness is enhanced.

  In the camera 10, the front right side wall surface 12 b of the front case 12 is configured to be inclined with respect to the front-rear direction so as to go to the left side toward the front side from the rear end position 12 c adjacent to the pre-mounting wall surface 42. Therefore, when viewed from the front from the front (see FIG. 1), a more tightened impression can be given even with the same size.

  In the camera 10, the first front end opening portion 47 a and the second front end opening portion 47 b are configured to be adjacent to the rear end position 12 c of the front right wall surface 12 b of the front case 12. In other words, the width dimension seen in the left-right direction of the case 11 can be minimized.

  In the camera 10, the intermediate case 13 is extended to the right side of the front case 12 and the rear case 14, and the middle upper wall surface 13 b and the middle bottom wall surface 13 c are looped with a belt-like surface smoothly passing through the palm harmony wall surface 43. The right contour ridgeline 44 (the ridgeline between the pre-attachment wall surface 42 and the palm harmony wall surface 43) of the protrusion 41 is positioned at the right end of the case 11 when viewed in the left-right direction. The outer edge of the case 11 is formed outside the mechanism housing space 26 in order to prevent the volume of the mechanism housing space 26 from being reduced while forming the right edge contour of the case 11 integrally with the right contour ridge line 44 as viewed from the entire case 11. It is possible to provide a strap insertion hole 45 at one position. For this reason, as described above, it is possible to easily attach the strap without making the hand gripped for the photographing operation (right hand RH in the above example) uncomfortable, and to improve the overall decorativeness and the small size. It is possible to make it.

  Therefore, in the camera 10 according to the present invention, the strap can be easily inserted into the strap insertion hole 45 without reducing the volume of the mechanism accommodating space 26 of the case 11 and when the case 11 is gripped, it is uncomfortable. You can prevent memorizing.

  In the above-described embodiment, the strap attachment portion 40 has the first strap insertion hole 45a and the second strap insertion hole 45b whose one end opens on the palm harmony wall surface 43 and the other end opens on the wall surface 42 before attachment. When the case 11 is gripped, the strap S can be easily inserted into the strap insertion hole 45 without reducing the volume of the mechanism accommodating space 26 of the case 11. However, the present invention is not limited to the above-described embodiment, as long as it can prevent the user from feeling uncomfortable. For example, the camera 10 ′ can be configured as shown in FIGS. In the camera 10 ′, the protrusion 41 ′ is configured to extend from the wall surface 42 ′ before attachment through the palm harmony wall surface 43 ′ to the wall surface 62 after attachment, as viewed in a cross section perpendicular to the vertical direction. The projecting body 41 ′ has an insertion hole 45 a ′ and a second strap insertion hole 45 b ′ (strap insertion hole 45 ′) such that one end opens the wall surface 62 after attachment and the other end opens the wall surface 42 ′ before attachment. It penetrates. In the camera 10 ′, a third strap that is elongated in the vertical direction instead of providing the terminal storage space 50 (see FIG. 7) below the first strap insertion hole 45 a ′ and the second strap insertion hole 45 b ′. An insertion hole 45c is provided. Here, the palm harmony wall surface 43 ′ in the camera 10 ′ is different from the extending direction seen in the cross section along the plane orthogonal to the vertical direction, and that one end of the strap insertion hole 45 ′ is not provided. The configuration is the same as the palm harmony wall surface 43 of the camera 10. Even in this camera 10 ′, as with the camera 10, the strap 11 can be easily inserted into the strap insertion hole 45 without reducing the volume of the mechanism accommodating space 26 of the case 11, and the case 11 is gripped. It is possible to prevent the user from feeling uncomfortable. Further, in the third strap insertion hole 45c, a belt-like strap Sb (see FIG. 10) can be inserted in the same manner as the first strap insertion hole 45a ′, and the position of the attached strap S is appropriately determined depending on the application. It can be shifted (see FIG. 11). As described above, the strap insertion hole 45 may be single or plural. When a plurality of strap insertion holes 45 are provided, the extension amount of the strap attachment portion 40 from the case 11 to the outside of the deflection side wall (in the above-described embodiment, from the right partition wall portion 13a of the intermediate case 13 to the right) is reduced. From the viewpoint, it is desirable to provide in series along the extending direction of the palm harmony wall surface 43 as in the above-described embodiment.
