  The main body portion 10 is formed in a substantially cylindrical shape, and has an opening 10a on one front side in the Z-axis direction (see FIG. 3), and is formed in a form in which the other back side is closed. Inside the main body 10, as described above, an image pickup unit including the image pickup device 11 and a drive circuit that drives the image pickup device, a control circuit that comprehensively controls the entire intermediate cylinder 1 with the image pickup device, and the like, A signal processing circuit for performing signal processing of an image signal acquired by the element 11 and various types of communication signals performed between external devices such as the portable electronic device 3 is provided (details will be described later). ).

  The image pickup device 11 has been conventionally put into practical use, for example, a photoelectric conversion device such as a CCD (Charge Coupled Device) image sensor or a CMOS (Complementary Metal Oxide Semiconductor) image sensor. The general form is applied.

  The opening 10a of the main body 10 is mechanically connected to a replacement lens barrel 7 (not shown in FIG. 3, etc .; see FIGS. 1 and 2) attached to the intermediate cylinder 1 with the image sensor. A mounting ring 12 to be secured is provided.

For example, on the outer surface of the main body 10, the upper surface (see reference numeral [4B] in FIG. 4) has a release operation member 15 interlocked with a release switch when performing an imaging operation, and a power operation member 17 interlocked with a power switch. Is arranged.

  Further, the replacement lens barrel 7 (see FIGS. 1 and 2) attached to the front surface of the intermediate cylinder 1 with the image sensor is removed from the right side surface of the main body 10 (see reference numeral [4E] in FIG. 4). At this time, a lens removal operation button 14 which is an operation member and an attachment adapter 4 (not shown in FIGS. 3 and 4; see FIGS. 1 and 2) attached to the back surface of the intermediate cylinder 1 with the image sensor are removed. An adapter removal operation button 18 is provided.

  The lens removal operation button 14 is an operation member that is interlocked with a lock pin 30 that is provided with a predetermined length region on the front end side that can project and retract from the mount surface 12a of the mount ring 12 to the outside. Here, the lens removal operation button 14, the lock pin 30, and the like are provided with a lens lock release mechanism for releasing the rotation lock state of the replacement lens barrel 7 attached to the front surface of the intermediate cylinder 1 with the image sensor. It is composed. The detailed configuration of this lens lock release mechanism will be described later with reference to FIGS.

  The adapter removal operation button 18 has a stopper pin 31 (see [4E] and [4F] in FIG. 4) in which a predetermined length region on the distal end side is projected and retracted from the surface of the adapter mounting portion 19 to the outside. This is an operation member linked to Here, the adapter removal operation button 18, the stopper pin 31, and the like remove the mounting adapter 4 (not shown in FIG. 3, etc .; see FIGS. 1 and 2) attached to the back surface of the intermediate cylinder 1 with the image sensor. Therefore, an adapter lock releasing mechanism that releases the rotation lock state of the lens barrel 7 is configured. The detailed configuration of this adapter lock release mechanism will be described later with reference to FIGS.

  On the other hand, strap attachment brackets 100 (not shown in FIG. 3; see FIG. 5) are detachably disposed on both side surfaces of the main body 10 (see reference numerals [4D] and [4E]). A suspension fitting mounting portion 16 is formed. Further, a tripod screw hole 20 is formed on the bottom surface of the main body 10 (see reference numeral [4C]).

  Here, the strap mounting bracket 100 will be described with reference to FIG. The strap-mounting hanging metal fitting 100 is a hanging fitting for attaching a strap (hanging string) or the like, and is fitted to the hanging fitting mounting portion 16 of the main body 10 and has a predetermined locking mechanism. And a loop-shaped hanging bracket 101 for passing a strap (hanging string) or the like.

  The lock mechanism of the strap mounting suspension 100 is configured as follows. That is, a biasing member (not shown) is urged at the tip of the hanging bracket body 102 in a direction orthogonal to the axial direction of the hanging bracket body 102 (that is, toward the radial direction of the hanging bracket body 102). An engaging claw 102a to be formed is formed. The front end side of the engaging claw 102a is formed in a tapered shape whose cross section has an inclination toward the front end. On the other hand, a circumferential groove (not shown) is formed inside the hanging bracket mounting portion 16 on the main body 10 side.

  Here, the hole diameter of the hanging fitting mounting portion 16 is formed to be slightly smaller than the outer diameter of the engaging claw portion 102 a of the hanging fitting main body 102. The diameter of the inner circumferential groove is slightly larger than the diameter of the hole of the hanging bracket mounting portion 16.

  Therefore, with this configuration, when the suspension fitting main body 102 is inserted into the suspension fitting mounting portion 16 on the main body portion 10 side, the engagement claw portion 102a slides on the inner wall surface of the suspension fitting mounting portion 16 at the tip tapered portion. However, the diameter is reduced against the urging force. Thereby, even the engaging claw portion 102 a having a diameter larger than the hole diameter of the hanging bracket mounting portion 16 can be inserted into the hanging bracket mounting portion 16. And when the engaging claw part 102a reaches the internal circumferential groove of the hanging fitting mounting part 16, the engaging claw part 102a returns to its original form from the reduced diameter state by its urging force. When the engaging claw 102 a is thus fitted into the inner circumferential groove of the hanging bracket mounting portion 16, the strap mounting hanging bracket 100 is mounted without being removed from the hanging bracket mounting portion 16.

  Further, in order to remove the attached strap attachment hanging bracket 100 from the attachment fitting mounting portion 16, for example, an operation of pressing or pulling the head portion 102b of the suspension fitting main body 102 of the strap attachment suspension fitting 100 toward the body portion 10 side is performed. By doing so, the diameter of the engaging claw 102a can be reduced against the urging force. Accordingly, the engagement state between the engaging claw portion 102a and the inner circumferential groove of the hanging bracket mounting portion 16 is released, so that the strap mounting bracket 100 can be pulled out.

  Note that the configuration of the strap-mounting hanging metal fitting 100 is substantially the same as that used in electronic devices that have been widely used in the past, and a detailed description thereof is omitted. Moreover, it is not restricted to the thing of the form mentioned above, For example, it is good also as a thing of the form using a screw etc.

  Returning to FIG. 4, the front surface of the mounting adapter 4 (see FIGS. 1 and 2) is connected to the back side of the main body 10 (see reference numeral [4 F]) with respect to the back surface of the intermediate cylinder 1 with the image sensor. An adapter mounting portion 19 is formed as a connecting portion for fixing. The adapter mounting portion 19 is formed in a projecting shape that protrudes rearward in a substantially tapered shape so that the front side connection portion of the mounting adapter 4 of this embodiment is engaged. A plurality of parts constituting an attaching / detaching mechanism for making the attaching adapter 4 of the present embodiment attachable / detachable to / from the intermediate cylinder 1 with an image sensor on the outer peripheral surface of the adapter mounting part 19. Are formed (see FIG. 4). In this embodiment, the bayonet claw 19a shows an example in which four places are arranged at intervals of about 90 degrees in the circumferential direction. These plural (four) bayonet claws 19a are bayonet with respect to a bayonet fitting portion 41 (see FIG. 6 and the like described later) formed on the outer peripheral edge portion of the front side connection portion of the mounting adapter 4 of the present embodiment. It is a constituent part to be combined.

  In addition, it is performed between the said intermediate cylinder 1 with an image pick-up element and external devices (for example, the said portable electronic device 3 etc.) on the back surface (refer code | symbol [4F] of FIG. 4) of the said intermediate cylinder 1 with an image pick-up element. Ensure electrical connection between the wireless on / off operation member 22 interlocked with the wireless switch for turning on / off the wireless communication use state and another external device via a wired cable (for example, a USB cable). A connection connector 23 and the like are provided for transmitting various data and supplying power from an external power supply device to a battery or the like. As the connection connector 23, a general standard product such as a mini USB connector or a micro USB connector is applied.

  Further, on the outer peripheral surface of the main body 10 of the intermediate cylinder 1 with an image sensor, for example, as shown in FIGS. Is provided. This index 10x is an index provided for positioning the mounting position when the mounting adapter 4 is mounted on the intermediate cylinder 1 with the image sensor. The index 10x is formed in a form that can be easily visually recognized by the user (user) by using, for example, a seal, engraving, molding, or the like, and coloring it with, for example, white or red. The index 10x may be provided at least at a predetermined position on the outer peripheral surface of the main body 10.

  Corresponding to the index 10x, on the mounting adapter 4 side, the mounting adapter 4 is imaged at a predetermined part on the outer peripheral surface thereof as shown in FIGS. An index for positioning the mounting position when mounting on the element-equipped intermediate cylinder 1 is provided. As a positioning index on the mounting adapter 4 side, a first index 40x corresponding to the index 10x on the intermediate cylinder 1 side with the image sensor, and the mounting adapter 4 and the image sensor provided in the vicinity of the first index 40x. A second index 40y indicating a mounting state with the attached intermediate cylinder 1 is provided. These two indicators 40x and 40y, like the indicator 10x, can be easily visually recognized by the user (user) by using, for example, a seal, engraving, molding, or the like and coloring them with white or red, for example. It is formed in various forms. Here, the first index 40x and the second index 40y are shown with different shapes, colors, and the like, for example. For example, the first index 40x is formed in the same shape as the index 10x (rectangular shape in the illustrated example) and in the same color, and the second index is a color different in shape (circular shape in the illustrated example) from the index 10x. It is formed with.

  Thus, by providing a predetermined index on both the intermediate cylinder 1 with the image pickup device and the mounting adapter 4, it is possible to easily perform relative positioning when combining the two. That is, when the mounting adapter 4 is attached to the intermediate cylinder 1 with the image pickup device, first, the two are opposed to each other so that the index 10x and the first index 40x match. Then, the bayonet fitting part 41 by the side of the adapter 4 for attachment is arrange | positioned in the vicinity of the bayonet nail | claw 19a by the side of the intermediate cylinder 1 with an image pick-up element. In this state, the mounting adapter 4 and the image pickup element-equipped intermediate cylinder 1 are relatively rotated. Then, the bayonet fitting part 41 fits into the bayonet claw 19a. Then, when the two are completely fitted, the index 10x on the intermediate cylinder 1 side with the image sensor matches the second index 40y on the mounting adapter 4 side as shown in FIGS. . Thereby, the user (user) can visually confirm that the intermediate cylinder 1 with the image pickup device and the mounting adapter 4 are in the proper wearing state.

  As described above, in the present embodiment, the bayonet coupling between the intermediate cylinder 1 with the image sensor and the mounting adapter 4 is realized by fitting the four bayonet claws 19a and the four bayonet fitting portions 41 together. doing. In this case, the fitting site | part of the said bayonet nail | claw 19a and the bayonet fitting part 41 is provided for every 90 degree angles in the circumferential direction.

Specifically, for example, as shown in FIG. 1, in addition to the normal configuration in which the imaging device 11 is mounted on the mounting adapter 4 so that the imaging device 11 is arranged in a horizontally long configuration, the imaging device 11 is illustrated. Although not provided, the intermediate cylinder 1 with the image sensor can be mounted on the mounting adapter 4 so that the image sensor 11 is arranged in a vertically long form. Therefore, in order to correspond to a plurality of mounting forms of the intermediate cylinder 1 with the image sensor and the mounting adapter 4, for example, the index 10 x is set on the outer peripheral surface of the main body 10 in the circumferential direction at an angle of approximately 90 degrees in total. You may make it provide four places.

  In this case, the same number of the first index 40x and the second index 40y may be provided at the corresponding positions so as to correspond to the plurality of indices 10x on the intermediate cylinder 1 with an image sensor.

  A part of the support shaft 47 is disposed so as to be exposed to the outside. In this case, for example, a hanging string (strap) can be passed through the exposed portion of the support shaft 47. With this configuration, the support shaft 47 functions as a support shaft in the hinge portion between the adapter main body 40 and the support lid 46 and at the same time functions as a strap attachment portion.

  The adapter main body 40 is configured so that it can be bayonet-coupled to the connection portion on the front surface side with the adapter mounting portion 19 (see FIG. 2, FIG. 4, etc.) on the back surface of the intermediate tube 1 with the image sensor. . As a configuration for that purpose, a plurality of bayonet fitting portions 41 are formed as connecting portions on the inner peripheral edge portion on the front side of the adapter main body 40. As described above, the plurality of bayonet fitting portions 41 are bayonet coupling portions that engage with a plurality (four places) of bayonet claws 19 a of the adapter mounting portion 19.

Four places are formed.

  Further, in the adapter main body 40, a portion rotated by an angle of approximately 180 degrees in the circumferential direction with respect to a connecting portion (hinge portion) with the support lid 46, that is, the center axis O 1 (the optical axis O of the mounting adapter 4). Point: Refer to the reference numerals [6A] and [6F] in FIG. 6). When the adapter main body 40 is put into a use state in which the adapter main body 40 is opened on the outer peripheral edge on the opposite side, the portable electronic device 3 A first holding arm 43 (not shown in FIG. 6; see FIG. 2) that contacts and holds one portion of the outer edge (specifically, one of the side surfaces (one side surface portion) of the portable electronic device 3). Projecting backwards. The first holding arm 43 is formed with an elastic body 55 (not shown in FIG. 6; not shown in FIG. 6) having a tip formed in a hook shape (hook shape) and an inner surface made of an elastic rubber member or the like as a non-slip member. A holding portion 43a attached with a reference) is disposed. Thereby, the first holding arm 43 holds a part of the outer edge portion of the portable electronic device 3, and the elastic body 55 comes into contact with a part of the outer edge edge portion of the portable electronic device 3, thereby The portable electronic device 3 can be reliably held.

  Furthermore, the adapter main body 40 is provided with a plurality of opening operation buttons 42 which are operation members for displacing the mounting adapter 4 in the closed state to the open state. Here, in the present embodiment, an example in which two opening operation buttons 42 are provided is shown. Specifically, the opening operation button 42 is configured so that the first holding arm 43 is sandwiched when the mounting adapter 4 is viewed from the front (FIG. 6 [6A]) or the back (FIG. 6 [6F]). 1 is arranged in the vicinity of the holding arm 43. The two opening operation buttons 42 are arranged so as to project and retract from the outer peripheral surface of the adapter main body 40 in the radial direction.

  The support lid 46 is provided so as to be rotatable with respect to the adapter main body 40. When the support lid 46 is opened with respect to the adapter main body 40, another part of the outer edge of the portable electronic device 3 (specifically, specifically, It becomes a support part which holds the other side (other side part) which opposes one side of the side of portable electronic equipment 3, and when the above-mentioned portable electronic equipment 3 is removed, it will be in a closed state to adapter main part 40. Thus, the storage state when not in use can be set.

  As shown in FIG. 6 and the like, the support lid 46 is pivotally supported with respect to the adapter main body 40 by a support shaft 47 inserted and arranged in the hinge arm portion 46a. Both ends of the support shaft 47 are fixed to the fixed portion 40a on the adapter body 40 side. In the support lid 46, a portion rotated by an angle of approximately 180 degrees in the circumferential direction with respect to a connection portion (hinge portion) to the adapter main body 40, that is, the center axis O 1 (the optical axis O of the mounting adapter 4) Point: A tip hook portion 48a of the second holding arm 48 is disposed on the outer peripheral edge portion on the opposite side across the reference numerals [9A] and [9F] in FIG. The tip hook portion 48a at the tip portion of the second holding arm 48 is another part (other side surface) of the outer edge portion of the portable electronic device 3 when the mounting adapter 4 is in an open state. This is configured so that it can be securely held by abutting against the portion. Therefore, the tip hook portion 48a is formed in a hook shape, and an elastic body 56 (see FIG. 6) made of an elastic rubber member or the like as a non-slip member is attached to the inner surface. . Thereby, the tip hook portion 48 a of the second holding arm 48 holds the other part (the other side surface portion) of the outer edge portion of the portable electronic device 3, and the elastic body 56 of the portable electronic device 3. The portable electronic device 3 can be reliably held by contacting another part (other side surface part) of the outer edge part.

  Further, when the mounting adapter 4 is closed, the tip hook portion 48a of the second holding arm 48 is a position that covers the outer peripheral portion of the first holding arm 43 on the outer peripheral edge of the adapter body 40. Placed in. At this time, it is configured that the closed state of the mounting adapter 4 is held by engaging the tip hook portion 48 a with the outer surface portion of the first holding arm 43.

  In addition, on the outer peripheral surface of the adapter main body 40 of the mounting adapter 4, as described above, two indexes corresponding to the index 10x on the intermediate cylinder 1 side with the image sensor, that is, the first index 40x and the second index An index 40y is provided. The above is the schematic configuration of the mounting adapter 4. Note that the mounting adapter 4 is not a main part of the present invention, and thus detailed description thereof is omitted.

[Detailed internal structure of intermediate cylinder with image sensor]
Next, details of the internal configuration of the intermediate cylinder 1 with an image sensor according to the present embodiment will be described below. First, detailed configurations of the lens lock release mechanism and the adapter lock release mechanism among the internal mechanisms in the intermediate cylinder 1 with the image sensor will be described below mainly with reference to FIGS. FIGS. 7 to 9 are views showing a part of the exterior of the main body of the intermediate cylinder with an image sensor in order to show the internal structure of the intermediate cylinder with the image sensor as an accessory device of the present embodiment. Among these, FIG. 7 is a right side view of the intermediate cylinder with an image sensor. 8 is a perspective view seen from the back side of FIG. 9 is a perspective view seen from the front side of FIG.

[Detailed internal structure of the intermediate tube with image sensor (lens lock release mechanism)]
First, a detailed configuration of the lens lock release mechanism applied in the intermediate cylinder 1 with an image sensor will be described. The lens lock release mechanism is a part of the lens attaching / detaching mechanism of the replacement lens barrel 7 attached to the front surface of the intermediate cylinder 1 with the image sensor, and rotates when the attached lens barrel 7 is removed. It is a mechanism part for canceling the locked state. This lens lock release mechanism is constituted by various components such as the lens removal operation button 14 and the lock pin 30.

  The configuration of the lens lock release mechanism will be described in further detail. The lens lock release mechanism includes a lens removal operation button 14, a first suspension shaft 24, a first operation button urging spring 25, a lock pin 30, a interlocking member 27, a lock pin urging spring 26, and a lock. It is comprised by components, such as the cancellation | release detection switch 21a and the board | substrate 21b.

  As described above, the lens removal operation button 14 is used when the lens barrel for replacement (see FIGS. 1 and 2) attached to the front surface of the intermediate cylinder 1 with the image sensor is removed. It is an operation member for releasing the rotation lock state of the cylinder 7.

  Here, on the side of the lens barrel 7, a lock concave hole (not shown) into which the lock pin 30 is fitted when the lens barrel 7 is attached to the intermediate cylinder 1 with the image sensor is formed. Yes. When the lock pin 30 is fitted into the lock recess, the rotation lock state of the lens barrel 7 is completed.

  That is, the lens lock release mechanism including the lens removal operation button 14 is a mechanism for releasing the rotation lock state of the lens barrel 7. The basic configuration of the lens lock release mechanism is substantially the same as the lens lock release mechanism in a conventional general interchangeable lens camera and an interchangeable lens barrel corresponding thereto.

  The lens removal operation button 14 has a button portion 14 a that protrudes from the outer surface of the main body portion 10, and a direction along the optical axis O of the imaging optical system of the lens barrel 7 that is attached to the intermediate cylinder 1 with the imaging element. It is arranged so as to be slidable within a predetermined range (in the Z-axis direction in FIG. 1). For this purpose, the lens removal operation button 14 is slidably supported along the first suspension shaft 24 inside the intermediate cylinder 1 with the image sensor. The first suspension shaft 24 is pivotally supported in parallel with the Z-axis direction along the optical axis O with respect to a fixed portion (not shown) inside the intermediate cylinder 1 with the image sensor.

  A first operation button urging spring 25 is wound around and disposed at a portion near the rear end of the first suspension shaft 24 between the internal fixing portion (not shown). Accordingly, the first operation button urging spring 25 urges the lens removal operation button 14 in the direction of the arrow Z1 shown in FIG. Further, the lens removal operation button 14 is formed with a convex interlocking portion 14b that protrudes in a direction orthogonal to the arrow Z1 direction inside the intermediate cylinder 1 with the image sensor. The convex interlocking portion 14b is disposed so as to contact the front surface of the arm portion 27a of the interlocking member 27 (details will be described later).

  On the other hand, a lock pin 30 is disposed in the vicinity of the lens removal operation button 14 and the first suspension shaft 24 in parallel with the first suspension shaft 24. The lock pin 30 is a member provided to restrict the rotation of the lens barrel 7 attached to the front surface of the intermediate cylinder 1 with the image sensor. The lock pin 30 is formed of a round bar-like member, and in a normal case, a predetermined length region of the tip portion thereof is directed from the surface of the mount surface 12a toward the front outside by the urging force of the lock pin urging spring 26. Projected.

  More specifically, the lock pin 30 is fitted and disposed at the tip of the lock ring 30 in the hole formed in the mount ring 12 of the intermediate cylinder 1 with the image sensor, and has a predetermined length from the hole toward the front outside. It is arranged in a protruding state.

  The rear end of the lock pin 30 is in contact with one section of the lock release detection switch 21a. An interlocking member 27 is fixed in the middle of the lock pin 30. The interlocking member 27 has an arm portion 27 a that protrudes in a circumferential direction orthogonal to the axial direction of the lock pin 30. The arm portion 27a is in contact with the rear end surface of the convex interlocking portion 14b. Further, a lock pin biasing spring 26 is wound around a portion near the rear end of the lock pin 30 and between the arm portion 27a of the interlocking member 27 and one section of the unlock detection switch 21a. Yes.

  With such a configuration, when the lens unlock mechanism is in a normal state, the lock pin biasing spring 26 biases the lock pin 30 toward the arrow Z1 along the optical axis O via the interlocking member 27. ing. Therefore, the tip of the lock pin 30 is thereby arranged with a predetermined length region protruding forward and outward from the mount surface 12a (see FIGS. 7 and 9). In this state, if a pressing force in the direction of the arrow Z2 is applied to the tip of the lock pin 30, the lock pin 30 is easily directed inward against the urging force of the lock pin urging spring 26. It will be in the form of being drawn in and immersive. That is, the lock pin 30 is disposed so as to protrude and retract in a direction along the optical axis O (Z-axis direction).

  The unlock detection switch 21a is a switch member mounted on the substrate 21b. The lock release detection switch 21a is formed by two pieces arranged to face each other. When the lock pin 30 moves in the direction of the arrow Z2, the lock release detection switch 21a detects the release of the rotation lock state of the lens barrel 7 when the lock pin 30 moves in the arrow Z2 direction. Is done.

  Further, as described above, the lens removal operation button 14 is urged in the direction of the arrow Z1 along the optical axis O by the first operation button urging spring 25. Therefore, in this state, the lens removal operation button 14 is in a state of being disposed at a position near the front surface of the intermediate cylinder 1 with the image sensor within a predetermined sliding range.

  When the lens unlocking mechanism is in the normal state, the user (user) slides the button portion 14a of the lens removal operation button 14 in the direction of the arrow Z2 shown in FIGS. To do. Then, the lens removal operation button 14 moves in the direction of the arrow Z2 against the urging force of the first operation button urging spring 25. Simultaneously with this movement, the convex interlocking portion 14b of the lens removal operation button 14 moves the arm portion 27a of the interlocking member 27 in contact with the biasing force of the lock pin biasing spring 26 in the direction of the arrow Z2. Move. In conjunction with this, the lock pin 30 also moves in the Z2 direction. Therefore, the distal end of the lock pin 30 moves in the Z2 direction so as to be drawn inward from the state of protruding from the mount surface 12a of the mount ring 12 to the front and outside to be immersed. At this time, the tip surface of the lock pin 30 moves to a position that is substantially flush with the mount surface 12a. Further, at this time, the rear end of the lock pin 30 presses one section of the unlock detection switch 21a toward the other section. Thereby, the two pieces of the lock release detection switch 21a come into contact with each other. In response to this, a predetermined detection signal indicating that the rotation lock state of the lens barrel 7 has been released is generated.

  When the lock pin 30 is in this state, the rotation lock state of the lens barrel 7 is released. Accordingly, when the user (user) is in this state, that is, while maintaining the sliding operation of the lens removal operation button 14 in the arrow Z2 direction, the lens mirror mounted on the intermediate cylinder 1 with the image sensor. The cylinder 7 is rotated in a predetermined direction. Thereby, the connection between the mount ring 12 of the intermediate cylinder 1 with the image sensor and the lens mount 7a (see FIG. 2) of the lens barrel 7 can be released. 1 can be removed.

  As described above, in the lens unlocking mechanism, the lens removal operation button 14 has the lock pin 30 in which a predetermined length region on the distal end side is provided so as to protrude and retract from the mount surface 12a of the mount ring 12 toward the front outside. It is comprised as an operation member interlock | cooperated with.

  With such a configuration, the intermediate cylinder 1 with an image sensor includes a lens lock release mechanism, and the interchangeable lens barrel 7 can be attached to and detached from the front side, so that a conventional general interchangeable lens camera can be used. Various types of interchangeable lens barrels supplied for use can be alternatively mounted and used.

  In addition, the lens lock release mechanism can release the lens lock state by simply performing a simple slide operation of one operation member (lens removal operation button 14), and the replacement lens barrel mounted in that state can be removed. The lens barrel can be easily removed simply by rotating it in a predetermined direction.

  Then, both of the intermediate cylinder 1 with the image pickup device and the replacement lens barrel 7 are rotated in a state where the predetermined alignment marks provided in advance are matched, and the rotation is restricted at that time. Since the lens is automatically locked when rotated to the position, the replacement lens barrel can be attached and detached very easily and reliably, and good operability can be realized.

[Detailed internal structure of the intermediate cylinder with image sensor (adapter unlocking mechanism)]
Next, a detailed configuration of the adapter lock release mechanism applied in the intermediate cylinder 1 with the image sensor will be described. The adapter lock release mechanism is a part of the adapter attachment / detachment mechanism of the attachment adapter 4 (see FIGS. 1 and 2) attached to and detached from the back surface of the intermediate cylinder 1 with the image sensor, and the attachment adapter 4 in the attached state is attached. It is a mechanism part for releasing the rotation lock state when removing. This adapter lock releasing mechanism is constituted by constituent members such as an adapter removing operation button 18 and a stopper pin 31.

  The adapter lock release mechanism includes an adapter removal operation button 18, a second suspension shaft 28, a second operation button urging spring 29, a stopper pin 31, a stopper pin urging spring 32, and an E ring. It is comprised by structural members, such as 33.

  The adapter removal operation button 18 is, as described above, the attachment adapter by the stopper pin 31 when the attachment adapter 4 (see FIGS. 1 and 2) attached to the back surface of the intermediate cylinder 1 with the image sensor is removed. 4 is an operation member for releasing the rotation lock state of FIG.

  Here, the connection between the back surface of the intermediate tube 1 with the image sensor and the front surface of the mounting adapter 4 will be described in detail later. A bayonet type in which a plurality of bayonet claws 19a provided at substantially equal intervals in the direction and a plurality of bayonet fitting portions 41 provided in an adapter body 40 (described later; see FIG. 6) of the mounting adapter 4 are engaged. The coupling means is applied.

  In this case, each bayonet claw 19a and each bayonet fitting portion 41 are engaged, and when the mounting adapter 4 is attached to the intermediate cylinder 1 with the image sensor, In the embodiment, the stopper pin 31 is configured so that a predetermined length region on the tip side protrudes from the surface of the adapter mounting portion 19 toward the rear outside at at least one of the four). Accordingly, the stopper pin 31 prevents the bayonet fitting portion 41 that has entered the bayonet claw 19a at the portion from rotating, and thus the rotation lock state of the mounting adapter 4 is completed.

  That is, the adapter lock release mechanism including the adapter removal operation button 18 is a mechanism for releasing the rotation lock state of the attachment adapter 4 mounted on the back surface of the intermediate cylinder 1 with the image sensor.

  The adapter removal operation button 18 has a button portion 18a projecting from the outer surface of the main body portion 10, and is disposed so as to be slidable within a predetermined range in the Z-axis direction of the intermediate cylinder 1 with the image sensor. For this purpose, the adapter removal operation button 18 is slidably supported along the second suspension shaft 28 in the intermediate cylinder 1 with the image sensor. The second suspension shaft 28 is pivotally supported in parallel with the Z-axis direction with respect to a fixed portion (not shown) inside the intermediate cylinder 1 with the image sensor.

  A second operation button urging spring 29 is wound around a portion near the front end of the second suspension shaft 28 and an internal fixing portion (not shown). Thereby, the second operation button urging spring 29 urges the adapter removing operation button 18 in the direction of the arrow Z2 by the urging force. The adapter removal operation button 18 is formed with a convex interlocking portion 18b (see FIG. 9) that protrudes in a direction orthogonal to the arrow Z2 direction inside the intermediate cylinder 1 with the image sensor. . The convex interlocking portion 18 b is disposed so as to engage with the stopper pin 31 and come into contact with the back surface of the E ring 33.

  On the other hand, a stopper pin 31 is disposed in the vicinity of the second suspension shaft 28 in parallel with the second suspension shaft 28. The stopper pin 31 is a member provided to restrict the rotation of the mounting adapter 4 attached to the back surface of the intermediate cylinder 1 with the image sensor. The stopper pin 31 is formed of a round bar-like member, and in a normal case, a predetermined length region of the tip portion thereof is directed from the surface of the adapter mounting portion 19 to the rear outside by the biasing force of the stopper pin biasing spring 32. Projected.

  More specifically, the stopper pin 31 is fitted and disposed at the tip of the stopper pin 31 in a hole formed in the adapter mounting portion 19 of the intermediate cylinder 1 with the image sensor, and has a predetermined length from the hole toward the rear outside. It is arranged in a protruding state.

  For this purpose, an E-ring 33 is fixed to a portion near the rear end of the stopper pin 31 so as to be integrated with the stopper pin 31. The E-ring 33 is formed to have a portion protruding in the circumferential direction orthogonal to the axial direction of the stopper pin 31. The second stopper pin urging spring 32 is wound around the stopper pin 31 between the E-ring 33 and an internal fixing portion (not shown) on the front side of the stopper pin 31. The front surface of the convex interlocking portion 18b is in contact with the back side of the E-ring 33.

  With such a configuration, when the adapter lock release mechanism is in a normal state, the second stopper pin urging spring 32 directs the stopper pin 31 in the arrow Z2 direction via the E ring 33 and the convex interlocking portion 18b. Energized. Therefore, by this, the tip of the stopper pin 31 is arranged in a state where a predetermined length region protrudes from the surface of the adapter mounting portion 19 to the outside outside. In this state, when a force is applied to the tip of the stopper pin 31, the stopper pin 31 is easily pulled inward against the biasing force of the second stopper pin biasing spring 32. It becomes an immersive form. That is, the stopper pin 31 is disposed so as to protrude and retract in the Z-axis direction.

  The adapter removal operation button 18 is urged in the arrow Z2 direction by the second operation button urging spring 29 as described above. Therefore, in this state, the adapter removal operation button 18 is in a state of being disposed in a portion closer to the back surface of the intermediate cylinder 1 with the image sensor within a predetermined sliding range.

  Thus, when the adapter unlocking mechanism is in the normal state, the user (user) slides the button portion 18a of the adapter removing operation button 18 in the direction of the arrow Z1 shown in FIGS. And Then, the adapter removal operation button 18 moves in the direction of the arrow Z1 against the urging force of the second operation button urging spring 29. Simultaneously with this movement, the convex interlocking portion 18b of the adapter removal operation button 18 abuts on the E-ring 33, and the E-ring 33 resists the urging force of the second stopper pin urging spring 32 in the direction of the arrow Z1. Move. In conjunction with this, the stopper pin 31 also moves in the Z1 direction. Therefore, the tip of the stopper pin 31 moves in the Z1 direction so as to be drawn in from the state of protruding from the surface of the adapter mounting portion 19 to the rear and outside and immersed therein. At this time, the tip surface of the stopper pin 31 moves to a position that is substantially flush with the surface of the adapter mounting portion 19.

  When the stopper pin 31 is in this state, the rotation lock state of the mounting adapter 4 is released. Accordingly, when the user (user) is in this state, that is, while maintaining the sliding operation of the adapter removal operation button 18 in the arrow Z1 direction, the user (user) is attached to the intermediate cylinder 1 with the image sensor. The adapter 4 is rotated in a predetermined direction. Accordingly, the connection between the adapter mounting portion 19 of the intermediate cylinder 1 with the image sensor and the adapter main body 40 (described later; see FIG. 7) of the mounting adapter 4 can be released. It can be made the state which can be removed from the intermediate cylinder 1 with an element.

  As described above, in the adapter lock release mechanism, the adapter removal operation button 18 is provided on the stopper pin 31 in which a predetermined length region on the distal end side is provided so as to protrude and retract from the surface of the adapter mounting portion 19 to the rear outside. It is configured as an interlocking operation member.

  As described above, in the present embodiment, the lens removal operation button 14 of the lens lock release mechanism and the adapter removal operation button 18 of the adapter lock release mechanism are connected to the right side surface of the main body 10 (FIG. 4). In the reference [4E], they are arranged side by side in the direction along the optical axis O at positions adjacent to each other. The operation directions of the lens removal operation button 14 and the adapter removal operation button 18 are configured to be the same direction, that is, the direction along the optical axis O. In this case, the operation direction at the time of unlocking the lens removal operation button 14 of the lens unlock mechanism is a direction toward the opposite side along the optical axis O with respect to the front surface side where the replacement lens barrel is mounted. is there. Further, the operation direction when the adapter removal operation button 18 of the adapter lock release mechanism is unlocked is the direction toward the opposite side along the optical axis O with respect to the back side on which the mounting adapter 4 is mounted. That is, the operation direction of the lens removal operation button 14 and the operation direction of the adapter removal operation button 18 are configured along the optical axis O and away from each other.

  With such a configuration, the intermediate cylinder 1 with an image sensor includes an adapter lock release mechanism, and the mounting adapter 4 can be attached to and detached from the back side, so that the existing one can be provided via the mounting adapter 4. An image pickup system that can be easily integrated with the portable electronic device 3 and that has substantially the same form as a conventional general image pickup device (camera) using the already-owned portable electronic device 3 Can be built.

[Detailed internal configuration of intermediate cylinder with image sensor (release operation member)]
Next, the detailed configuration of the release operation member of the plurality of operation members among the internal mechanisms in the intermediate cylinder 1 with the image sensor will be described below mainly with reference to FIGS. 10 to 13 are diagrams illustrating the configuration of a release operation member in the intermediate cylinder with an image sensor that is an accessory device of the present embodiment. Among these, FIG. 10 is an enlarged perspective view of a main part, showing a fixing member (upper cover) and a release operation member provided at the upper surface portion inside the main body of the intermediate cylinder with the image sensor. FIG. 11 is a perspective view showing the structure on the inner surface side of only the release operation member shown in FIG. FIG. 12 is an enlarged cross-sectional view of a main part showing an enlarged cross section in the YZ plane including the release operation member. FIG. 13 is an enlarged cross-sectional view of a main part showing an enlarged cross section in the XY plane including the release operation member.

  In the main body 10 of the intermediate cylinder 1 with an image sensor according to the present embodiment, an upper cover 60 that is a fixing member having a form as shown in FIG. The upper cover 60 is provided with various components (such as operation members such as the release operation member 15 and the power supply operation member 17) provided inside the intermediate cylinder 1 with the image sensor, and the intermediate cylinder with the image sensor. 1 is a member provided to suppress deformation or the like when the main body 10 covering the outer surface of 1 receives an impact or the like. For the upper cover 60, for example, a molded part formed by resin molding or the like is applied.

  Since the main body portion 10 is formed in a substantially cylindrical shape as a whole, the upper cover 60 is formed to have an arcuate surface along the inner wall surface of the peripheral surface of the main body portion 10. The main body 10 is disposed so as to cover the arc-shaped surface of the upper cover 60 (see FIG. 3 and the like). In this case, a release operation member 15, a power supply operation member 17, and the like are disposed on the upper surface side of the intermediate cylinder 1 with the image sensor and on the upper surface portion of the arc-shaped surface of the upper cover 60. Therefore, holes 10b and 10c (see FIGS. 12 and 13) are formed in the main body 10 so that the surfaces of the release operation member 15 and the power supply operation member 17 are exposed to the outside. Hereinafter, the structure of the release operation member 15 and the portion where the release operation member 15 is disposed will be described in detail.

  As shown in FIGS. 10 and 11, the release operation member 15 is a thin plate that is substantially elliptical as a whole, has an arc-shaped surface along the peripheral surface of the main body 10, and has elasticity. It is the operation member comprised provided with the shape part. As the release operation member 15, for example, a molded part by resin molding or the like is applied. As shown in FIG. 12, the outer surface of the release operation member 15, that is, the surface exposed to the outside in the state where the release operation member 15 is assembled to the intermediate cylinder 1 with the image sensor is substantially flush with the outer surface of the main body 10. As shown in FIG. 12, the release operating member 15 has a substantially concave shape facing inward.

  The outer surface of the release operation member 15 is a part where the user (user) normally presses the release operation member 15 by touching the abdomen of a finger or the like. Therefore, as described above, the outer shape of the release operation member 15 is set to be substantially the same plane as the outer surface of the main body 10 and has a substantially concave shape with the cross section facing inward. Can recognize the disposition position of the release operation member 15 provided on the outer surface of the intermediate cylinder 1 with the image pickup element without visually recognizing the release operation member 15 only by a tactile sensation by the abdomen of the finger or the like. It has a configuration.

  On the inner surface side of the release operation member 15, as shown mainly in FIG. 11, various protruding shapes such as a pressing convex portion 15 a, a snap fitting portion 15 c, and a position restricting protruding portion 15 d are formed. Among these, the pressing convex portion 15 a is a rod-like protruding shape portion that protrudes from the vicinity of the substantially central portion of the release operation member 15 toward the inner surface. The pressing convex portion 15 a is disposed so as to be movable in the Y-axis direction with respect to the upper cover 60 in a state where the pressing convex portion 15 a is inserted into the hole 60 a (see FIG. 10) on the upper surface of the upper cover 60. In this state, the tip of the pressing convex portion 15 a is disposed in contact with a release switch 71 (see FIGS. 12 and 13) provided inside the main body 10. The release switch 71 is a switch member made of a flexible printed board or the like mounted on a switch board 70 (see FIGS. 12 and 13) placed on the internal fixing portion of the upper cover 60.

  The snap fit portions 15c are a pair of projecting shape portions that project from the vicinity of both end edges in the minor axis direction toward the inner surface of the substantially elliptical shape of the release operation member 15 and have claw-shaped portions at the tips. When each of the snap fit portions 15c is inserted and arranged in a pair of holes 60c (see FIG. 10) on the upper surface of the upper cover 60, the claw-shaped portions are locked in the holes 60c. It is comprised so that it may be latched by the part 60cc (refer FIG. 13). As a result, the release operation member 15 is configured to be restricted from moving outward in the Y-axis direction and not fall off from the upper cover 60. On the other hand, the hole 60c has a space 60cb that allows inward movement in the Y-axis direction with the snap-fit portion 15c inserted and arranged. With this configuration, the release operation member 15 is not removed in a normal state and is maintained attached to the upper cover 60. On the other hand, when a pressing operation by a user (user) is received, It can move in the direction of subduction towards the direction. As a result, the tip of the pressing protrusion 15 a is configured to press the release switch 71.

  Further, the position restricting projection 15d is provided so as to project from the vicinity of both end edges in the major axis direction of the release operation member 15 toward the inner surface, and has a notch engaging portion 15b at a substantially central portion. It is a pair of protruding shape part made. Each of the position restricting projections 15d is placed on a pair of cutouts 60d (see FIG. 10) on the upper surface of the upper cover 60 when the snap fit portion 15c is inserted into the hole 60c and is locked. It will be in the state. When this state is reached, the protrusion 60b formed at the substantially central portion of the notch 60d is engaged with the notch engaging portion 15b of the position restricting protrusion 15d. As a result, the release operation member 15 is restricted from moving in the Z-axis direction. On the other hand, in the same state, when the release operation member 15 receives a pressing operation by the user (user), the release operation member 15 sinks inward in the Y-axis direction as described above, and at the same time has its long axis by its own elastic force. It is configured to bend in the direction. The tip of the pressing convex portion 15 a presses the release switch 71. At this time, the release operation member 15 is bent in the long axis direction so that the dimension of the release operation member 15 in the long axis direction is extended. In order to absorb this extension allowance, the hole 10b of the main body 10 is formed to be slightly larger than the dimension of the release operation member 15 in the major axis direction. Thereby, the hole 10b of the main body 10 allows the release operation member 15 to bend.

  As described above, the release operation member 15 has a substantially concave shape in which the outer edge portion is substantially flush with the outer surface of the main body 10 and the cross section is directed inward in the outer surface shape. The arrangement position of the release operation member 15 can be recognized only by a tactile sensation by the abdomen of the finger without visually recognizing the release operation member 15.

  Therefore, the user (user), for example, is in a situation where the surrounding environment is dark and the hand is not visible, or the usage mode in which the operation system of the device held by the hand is reversed, specifically, for example, imaging by himself / herself Even if you perform an operation in the so-called groping situation, such as when you shoot yourself with the lens facing, or when you shoot toward the subject with the equipment held in your hand raised, It is possible to provide an intermediate cylinder with an image pickup element with excellent operability that can always reliably perform a shutter release operation while reliably grasping the device itself.

[Detailed internal structure of the intermediate cylinder with image sensor (frame structure)]

FIG. 19 is a vertical cross-sectional view of the intermediate cylinder with an image sensor according to the present embodiment as viewed from the right side with the exterior member removed. FIG. 19 shows a cross section taken along line [19]-[19] in FIG.

  As shown in FIG. 14, a basic configuration unit that is provided inside the intermediate cylinder 1 with an image sensor according to the present embodiment and forms a basic configuration unit of the intermediate cylinder 1 with an image sensor includes a front body 64 and a back surface. The frame 65 and the front frame 66 are mainly configured.

  The front body 64 is a member that mainly configures the basic structure on the front side inside the main body 10. The front body 64 is formed such that its outer peripheral edge shape is matched with the substantially cylindrical shape of the main body portion 10 so that it can be interpolated with respect to the main body portion 10. As a whole, it is formed in a substantially annular shape so as to have an opening that matches the opening 10a. For this purpose, the front body 64 is fixedly disposed at a position closest to the front surface inside the main body 10. Various types of internal components of the intermediate cylinder 1 with the image sensor are attached to the front body 64 at predetermined positions. For example, the mount ring 12 is fixed to the front surface of the front body 64 with screws or the like. The front body 64 is formed as a die-cast part manufactured using, for example, a metal material.

  The back frame 65 is a member mainly constituting the basic structure on the back side inside the main body 10. The rear frame 65 has an outer peripheral shape formed in a substantially disc shape so as to match the substantially cylindrical shape of the main body 10 so that the back frame 65 can be interpolated with respect to the main body 10. For this purpose, the back frame 65 is fixedly disposed at a position closest to the back surface inside the main body 10. Thereby, the back frame 65 is a member that closes the back side of the main body 10. Various types of internal components are attached to both sides of the rear frame 65 (details will be described later). The back frame 65 is formed with a plurality of holes having a predetermined shape at predetermined positions in order to expose a part of the components disposed inside to the outside. The details of the plurality of holes in the back frame 65 will be described later. For example, some of the electronic components mounted on the main board 72 (see FIGS. 15 to 17 and the like) of the intermediate cylinder 1 with the image sensor are exposed. For this purpose, there is an opening hole 65a formed through a part thereof. The back frame 65 is formed by using a plate-like member made of metal (for example, stainless steel (SUS) or the like) or hard resin.

  The front frame 66 is configured by bending a plate-shaped member made of, for example, metal (for example, stainless steel (SUS) or the like), and is a constituent member that forms a main part of the basic constituent unit in the intermediate cylinder 1 with the image sensor. The front frame 66 is formed in a position near the front surface in parallel with the XY plane, and has a front flat plate portion 66a provided with an opening that matches the opening 10a of the main body portion 10 at the approximate center thereof, and the four-side outer peripheral edge portion of the flat plate portion. A plurality of flat plate portions (upper surface flat plate portion 66b, bottom flat plate portion 66c, right side surface) that extend from the rear to the rear side (back side) and are formed in parallel with the four planes of the upper surface, the bottom surface, the right side surface, and the left side surface. A flat plate portion 66d and a left side flat plate portion 66e). Here, the right side surface means the side surface on the right hand side toward the front surface (see FIG. 4 [4A]) of the intermediate cylinder 1 with an image sensor. Similarly, the left side surface refers to a side surface on the left hand side facing the front surface (see FIG. 4 [4A]) of the intermediate cylinder 1 with an image sensor.

  Accordingly, with this configuration, the front frame 66 is formed in a substantially rectangular parallelepiped shape as a whole. The front frame 66 itself has a substantially rectangular parallelepiped shape with an opening on the back side. However, as described later, when the front frame 66 is assembled as a part of the basic structural unit, the front side The opening on the back side of the frame 66 is closed by the back frame 65. The front frame 66 formed in this way is an important component in the intermediate cylinder 1 with the image sensor, as will be described in detail later, in an internal space surrounded by the flat plate portions (66b, 66c, 66d, 66e). For example, an image pickup unit including a power supply battery 81 and an image pickup device 11, a main board 72, and the like are disposed (see FIGS. 18 and 19).

  The front frame 66 is fixed to the front body 64 on the front side and to the back frame 65 on the back side, for example, using screws 66x, for example. . In other words, the front frame 66 is fixedly disposed inside the main body 10 so as to be sandwiched between the front body 64 and the back frame 65. The front body 64 is fixedly disposed at a portion near the front surface of the main body 10 and the back frame 65 is disposed at a portion near the back surface. With this configuration, when the basic configuration unit in the intermediate cylinder 1 with the imaging element is assembled by the front body 64, the back frame 65, and the front frame 66 (the configuration shown in FIG. 14), the front frame 66 The opening on the back side is closed by the back frame 65. And the basic composition unit comprised in this way will be inserted in the said main-body part 10, and the outer surface side will be covered and it will be in the form protected. At this time, a portion formed in a substantially rectangular parallelepiped shape in the front frame 66 is configured to be disposed in a substantially central portion of the main body portion 10.

  As described above, the main body 10 is formed in a substantially cylindrical shape. On the other hand, the front frame 66 is formed in a substantially rectangular parallelepiped shape as a whole. A substantially rectangular parallelepiped front frame 66 is disposed at a substantially central portion inside the substantially cylindrical main body 10. In this case, the respective flat portions of the front frame 66, that is, the outer surface side of each of the upper surface flat plate portion 66b, the bottom surface flat plate portion 66c, the right side flat plate portion 66d, and the left side flat plate portion 66e, A space having a predetermined shape whose cross section has an arc shape is formed between them. When such a space is formed inside the main body 10, the outer surface of the main body 10 is easily deformed by buckling stress when an impact is applied to the outer surface of the main body 10. There is a risk of it.

  Therefore, as described above (see FIG. 10 and the like), the upper cover 60, which is a fixing member, is provided on the upper surface portion (the upper surface flat plate portion 66b of the front frame 66) of the main body portion 10, thereby buckling the main body portion 10. The stress is reinforced. In exactly the same manner, as shown in FIG. 15 and the like, the lower cover 61 is provided on the bottom surface portion (the bottom plate portion 66c of the front frame 66), and the right side portion (the right side surface of the front frame 66) in the main body portion 10. A right side cover 62 (see FIG. 15) is provided on the flat plate portion 66d), and a left side cover (not shown) is provided on the left side portion (left side flat plate portion 66e of the front frame 66). The bottom plate portion 66c is provided so as to cover the outer surface of the lower cover 61. The bottom plate portion 66c is provided with a tripod mounting component unit (not shown) for installing the tripod screw hole 20. With this configuration, the bottom flat plate portion 66c of the front frame 66 functions to reinforce the exterior of the bottom surface side, and also functions as a reinforcing member for the tripod attachment portion.

  Similar to the upper cover 60, the lower cover 61, the right side cover 62, and the left side cover are also formed to have an arcuate surface along the inner wall surface of the main body 10, and various internal components are fixedly arranged. ing. And the main-body part 10 is arrange | positioned so that the circular arc-shaped surface of each cover (60, 61, 62 etc.) may be covered. Thus, each cover (60, 61, 62, etc.) prevents deformation and breakage of the main body 10 and protects internal components. For example, a molded part formed by resin molding or the like is applied to each cover (60, 61, 62, etc.). These covers (60, 61, 62, etc.) are fixed to the front body 64 and the back frame 65 by screws 60x (see FIG. 15), for example.

[Detailed internal structure of the intermediate cylinder with image sensor (back of the rear frame)]
As described above, and as shown in FIGS. 14, 15, 17, etc., the back frame 65 is provided with an opening hole 65a. A part of the main board 72 disposed in the internal space of the front frame 66 is disposed in the opening hole 65a. As a result, some of the electronic components mounted on the main board 72, such as the memory card slot 34 and the opening of the connection connector 23, are exposed from the opening hole 65a toward the back side outside of the back frame 65.

Electronic components such as a wireless on / off switch 76 for switching are mounted and arranged.

  Here, the rear substrate 73 on which the sensor element 75 and the like are mounted is separated from the main substrate 72. Since the main board 72 is a main board on which important electronic components (such as a control circuit) in the intermediate cylinder 1 with the image sensor are mounted, it is desirable that the main board 72 be disposed in the internal space of the front frame 66. Therefore, the main board 72 is disposed in the inner space of the front frame 66 so as to be parallel to the left side surface, that is, the inner surface of the left side plate portion 66e of the front frame 66 (details will be described later; FIG. 18, FIG. 19).

  On the other hand, it is desirable that the sensor element 75 such as a gyro sensor is disposed on a surface parallel to the light receiving surface of the image sensor 11. Here, as will be described later, the imaging element 11 is disposed such that its light receiving surface is parallel to the XY plane. Therefore, the rear substrate 73 on which the sensor element 75 and the like are mounted is also arranged in parallel with the back frame 65 that is parallel to the XY plane.

  On the other hand, a switch lever 77 constituting a part of the wireless switch mechanism that acts on the wireless on / off switch 76 is arranged so as to be slidable within a predetermined range in the X-axis direction on the outer surface on the rear side of the rear frame 65.

As shown in FIG. 17, the switch lever 77 is integrally formed with the wireless on / off operation member 22 serving as an operation unit operated by a user (user) and an arm portion 77 a acting on the wireless on / off switch 76. It is the plate-shaped member formed.

  Here, the wireless on / off operation member 22 of the switch lever 77 is configured to be exposed to the outside when the adapter mounting portion 19 is mounted on the back side of the intermediate cylinder 1 with the image sensor. . In this state, the wireless on / off operation member 22 is movable within a predetermined range in the direction along the X axis. For this purpose, the main body member 19c and the lid member 19b of the adapter mounting portion 19 are provided with openings formed with long axes in the direction along the X axis at the corresponding portions. This opening defines a movement range of the switch lever 77 in the X-axis direction.

  With such a configuration, when the user (user) picks up the wireless on / off operation member 22 which is a part of the wireless switch mechanism from the outside and slides it in the X-axis direction, The switch lever 77 also moves in the same direction. As a result, the arm 77 a acts on the wireless on / off switch 76. In response, the wireless on / off switch 76 issues a wireless function on / off switching signal. This instruction signal is transmitted from the rear board 73 to the control circuit on the main board 72 via the connection flexible printed board 74.

The protective glass 95 is provided behind the opening 67 a and on the front side of the light receiving surface of the image sensor 11, and is disposed in parallel with the light receiving surface of the image sensor 11. The protective glass 95 also serves to seal a predetermined space on the front side of the image sensor 11. As a result, the protective glass 95 prevents dust or the like entering the inside from the opening 67 a from adhering to the light receiving surface of the image sensor 11. The protective glass 95 is configured to vibrate upon receiving an excitation drive by an excitation drive mechanism (not shown) configured with, for example, a piezoelectric element.

  The holding member 94 is a fixing member that supports the outer edge portion of the protective glass 95 and holds the protective glass 95 parallel to the light receiving surface of the imaging device 11 while allowing vibrations by the vibration driving mechanism. Note that the holding member 94 functions as a member that simultaneously fixes and holds the imaging unit as described later.

  With this configuration, the dust removing unit seals the predetermined space on the front surface side of the image sensor 11 with the protective glass 95 and then vibrates the protective glass 95 via a vibration member such as a piezoelectric element.

  Further, a power battery 81 is disposed behind the heat radiating plate 96. The power supply battery 81 is a secondary battery of a general form such as a rechargeable battery such as a lithium ion secondary battery. The power battery 81 is disposed in a battery housing chamber formed in a portion near the back surface in the internal space of the front frame 66. A battery support member 85 that matches the outer shape of the power battery 81 to be applied is provided in the battery storage chamber.

[Detailed internal configuration of intermediate cylinder with image sensor (configuration and arrangement of wireless communication means)]
Next, among the internal components of the intermediate cylinder 1 with an image sensor according to the present embodiment, a plurality of units provided for performing wireless communication with other external devices to transmit and receive control signals and image data. The configuration and arrangement of the wireless communication unit will be described below mainly with reference to FIGS.

  FIG. 20 is a diagram illustrating an internal configuration by breaking a part of the main body of the intermediate cylinder with an image sensor according to the present embodiment, and the right side surface is shown with the adapter mounting portion removed from the intermediate cylinder with the image sensor. It is the perspective view seen from the position near the back. FIG. 21 is a diagram showing the internal configuration of the intermediate cylinder with an image sensor according to the present embodiment, in which the main body and the adapter mounting part are removed, and is a perspective view of the left side as viewed from the back side.

  20 and 21, illustration of the front frame 66 is omitted to show various internal components disposed in the internal space of the front frame 66. In other words, the main board 72 is actually configured such that the outer surface side thereof is covered with the left side flat plate portion 66e of the front frame 66 (not shown), but in FIG. Since the illustration is omitted, the main board 72 is shown.

  FIG. 22 is a top view of the intermediate cylinder with an image sensor in the state of FIG. FIG. 23 is a right side view of the intermediate cylinder with an image sensor in the state of FIG.

  The intermediate cylinder 1 with an image sensor according to the present embodiment transmits and receives control signals, setting data, and other image data acquired by the imaging unit in the intermediate cylinder 1 with an image sensor to and from other external devices. A plurality of inter-device interconnection communication means (hereinafter simply abbreviated as communication means).

  Here, the intermediate cylinder 1 with an image sensor according to the present embodiment includes two wireless communication means and one wired communication means. Specifically, the intermediate cylinder 1 with an image sensor according to the present embodiment complies with, for example, a Wi-Fi (Wireless Fidelity) standard which is one of the standards of a wireless LAN (Run; Local Area Network). A first wireless communication unit (87, 87a; described later) as a wireless communication unit and a second wireless communication unit (88 as a wireless communication unit compliant with the Bluetooth standard, which is one of the short-range wireless communication standards) , 88a (to be described later).

  Note that, as described above, the intermediate cylinder 1 with an image sensor according to the present embodiment includes the general-purpose interface standard connection connector 23 that conforms to, for example, the USB (Universal Serial Bus) standard. The intermediate cylinder 1 with the image pickup device is configured so that wired communication, power feeding, and the like can be performed with another external device via a connection cable connected to the connection connector 23. About the wired communication part including this connection connector 23, the detailed description is abbreviate | omitted as the technique generally put into practice conventionally is applied.

  One first wireless communication unit of the two wireless communication means includes a first communication antenna 87a and a first communication circuit that handles various electric signals input / output via the first communication antenna 87a. It is mainly configured by a first communication board 87 on which (not shown) is mounted. As shown in FIGS. 20 to 23, the first communication substrate 87 is disposed on the right side surface of the intermediate cylinder 1 with the image sensor. Specifically, the first communication substrate 87 is disposed along the outer surface of the right side flat plate portion 66 d that is one plane of the front frame 66.

  On the first communication board 87, the first communication antenna 87a is mounted and arranged as described above. In this case, the first communication antenna 87a is disposed on the right side surface of the intermediate cylinder with an image sensor 1 near the top surface and near the back surface.

  Although not specifically shown, the first communication board 87 is electrically connected to the main board 72 through an internal wiring such as a flexible printed board or a lead wire. Accordingly, various electrical signals received by the first communication antenna 87a of the first communication board 87 are thereby transmitted to the control circuit (CPU 72a) mounted on the main board 72. The image data acquired by the imaging device 11 is transmitted to the first communication board 87 via the main board 72 and transmitted from the first communication antenna 87a to the external device. ing.

  The other second wireless communication unit of the two wireless communication means is a second communication antenna 88a and a second that handles various electrical signals that are input and output wirelessly via the second communication antenna 88a. It is mainly configured by a second communication board 88 on which a communication circuit (not shown) is mounted. As shown in FIGS. 20 to 23, the second communication substrate 88 is disposed on the upper surface of the intermediate cylinder 1 with the image sensor. Specifically, the second communication board 88 is disposed along the outer surface of the upper surface flat plate portion 66b which is a plane substantially orthogonal to the right side flat plate portion 66d of the front frame 66.

  On the second communication substrate 88, the second communication antenna 88a is mounted and disposed as described above. In this case, the second communication antenna 88a is disposed at a substantially central portion in the front-rear direction (Z-axis direction) on the upper surface of the intermediate cylinder 1 with the image sensor and closer to the right side surface.

  Although not specifically shown, the second communication board 88 is also similar to the first communication board 87, for example, the main board via an internal wiring such as a flexible printed board or a lead wire. 72 is electrically connected. Accordingly, various electrical signals received by the second communication antenna 88a of the second communication board 88 are thereby transmitted to the control circuit (CPU 72a) mounted on the main board 72. A control signal or the like from the CPU 72a of the main board 72 is transmitted to the second communication board 88 and transmitted from the second communication antenna 88a to an external device.

  Here, for example, metal parts or the like are not arranged on the outer surface side or the vicinity of the first communication antenna 87a and the second communication antenna 88a so as not to hinder wireless communication by each wireless communication unit. It has a configuration.

  That is, the outer surface side of the first communication antenna 87a is covered with the right side cover 62, and the outer surface side of the second communication antenna 88a is covered with the upper cover 60. The right side cover 62 and the upper cover 60 are not shown in FIGS. 20 to 24, but see FIG. And the outer surface side of these right side cover 62 and the upper side cover 60 is arrange | positioned so that the main-body part 10 may further cover. Here, the right side cover 62 and the upper cover 60 are configured by molded parts by resin molding or the like. Further, the main body 10 is also configured using a member made of the same material as the cover member.

  By the way, in the intermediate cylinder 1 with an image sensor according to the present embodiment, as described above, the wireless communication unit compliant with the Wi-Fi (Wireless Fidelity) standard is applied as the first wireless communication unit. In addition, as the second wireless communication unit, wireless communication means compliant with the Bluetooth standard is applied.

  In general, the Wi-Fi standard wireless communication means applied to the first wireless communication unit is suitable for high-speed transfer of large-capacity files. Therefore, in this embodiment, the 1st wireless communication part shall be mainly used when transmitting the image data acquired by the imaging unit of the intermediate cylinder 1 with an image sensor to another external apparatus.

  In general, the Bluetooth standard wireless communication means applied to the second wireless communication unit is suitable for use in transmitting and receiving control signals and the like. Therefore, in the present embodiment, the second wireless communication unit receives a control signal from another external device (for example, the portable electronic device 3 or the like) or receives various setting information from the intermediate cylinder 1 with the image sensor. Is mainly used when transmitting to other external devices.

  On the other hand, the Wi-Fi of the first wireless communication unit and the Bluetooth of the second wireless communication unit share a frequency band of wireless communication (for example, 2.4 GHz band wireless communication). Therefore, when using both at the same time, there is a possibility that mutual wireless communication interferes. When such communication interference occurs, problems such as a decrease in data transfer speed may occur.

  Accordingly, the respective arrangements of the two wireless communication means, the first communication antenna 87a of the first wireless communication unit and the second communication antenna 88a of the second wireless communication unit, inside the intermediate cylinder 1 with the image sensor. It is necessary to devise. For example, a fixed spatial distance is provided between the first communication antenna 87a and the second communication antenna 88a, or the arrangement is such that the antennas do not overlap as much as possible. Furthermore, even when the portable electronic device 3 is mounted on the back side of the intermediate cylinder 1 with the image sensor, it is necessary to devise an arrangement that does not affect the two wireless communications.

  As a contrivance for this, in the present embodiment, as a result of various trials and examinations on the arrangement of the first communication antenna 87a and the second communication antenna 88a inside the intermediate cylinder 1 with the image sensor, Such an arrangement is applied as a desirable form.

  That is, the first communication antenna 87a is disposed on the right side surface of the intermediate cylinder 1 with the image sensor on the portion near the top surface and near the back surface. On the other hand, the second communication antenna 88a is disposed at a position near the right side surface of the intermediate cylinder 1 with the image sensor, which is a substantially central portion in the front-rear direction (Z-axis direction).

  By arranging the two wireless communication means in such a form, for example, even when both are used simultaneously, the two different forms of wireless communication are always maintained well without interfering with each other. Has realized.

  In general, the Bluetooth of the second wireless communication unit is suitable for a usage situation in which the second wireless communication unit is always connected without being aware of the wireless connection state. Therefore, in the intermediate cylinder 1 with an image sensor of the present embodiment, the wireless on / off operation member 22 and the wireless on / off switch 76 turn on and off the first wireless communication unit, and the second wireless communication unit captures an image. It is configured to be turned on and off in conjunction with the main power on / off state of the element-equipped intermediate cylinder 1.

  Further, the present invention is not limited to such a form. As another form, for example, the power state of the second wireless communication unit is always on regardless of the main power state of the intermediate cylinder 1 with the image sensor, and is always other. It may be in a standby state for receiving a control signal from the external device. In this configuration, when the second communication unit receives a control signal from another external device, the control circuit (CPU 72a) on the main board 72 of the intermediate cylinder 1 with the image sensor receives the control signal. Control to activate the intermediate cylinder 1 with an image sensor is possible. Therefore, for example, remote operation including on / off control of the power state of the intermediate cylinder 1 with an image sensor can be performed from a position away from the intermediate cylinder 1 with an image sensor by another external device.

  In the above-described embodiment, Wi-Fi and Bluetooth are specifically exemplified as application examples of two different forms of wireless communication means. However, the present invention is not limited to these. For example, It is also conceivable to apply NFC (Near Field Communication) or the like as another form of wireless communication means.

  The above is the main configuration of the intermediate cylinder 1 with an image sensor that is an accessory device of the present embodiment. The intermediate cylinder 1 with an imaging element configured as described above is an apparatus that can function as an imaging apparatus (camera) by itself when the replacement lens barrel 7 is mounted on the front surface.

  In the description of the present embodiment, further detailed illustration and description of the intermediate cylinder 1 with the image sensor is omitted, but as an internal configuration other than the above-described configuration, for example, the device status such as a power status is represented. A simple display unit to be obtained, a microphone for sound acquisition, and the like are provided. Here, as an example of the voice acquisition microphone, for example, a pair of microphones 79 is disposed in a portion near the front surface of the upper cover 60, more specifically, in a region between the mount ring 12 and the release switch 71. . Correspondingly, an opening (not shown) for voice input / output is provided at a corresponding portion of the main body 10. Although not shown in the drawings, the voice input / output opening is provided at a predetermined interval in the circumferential direction in a portion near the front surface of the main body 10, that is, in a region between the mount ring 12 and the release operation member 15. Two (a pair) are provided.

  Here, it is desirable that the pair of openings is located on the upper surface side of the main body 10 and closer to the mount ring 12 than the release operation member 15. Of course, the arrangement of the pair of microphones 79 also corresponds to this. On the upper surface side of the main body 10, in addition to the release operation member 15, for example, there is a power supply operation member 17 at a site near the back surface. Various operation members are also disposed on the side surface and the bottom surface of the main body 10. Therefore, there is a high possibility that the user's (user) fingers or the like are placed in the vicinity of these operation members including the release operation member 15 during use of the device. If the opening is closed with fingers or the like, voice input to the microphone 79 is hindered. In order to avoid such a situation, the pair of openings (the pair of microphones 79) are arranged as far as possible from various operation members (switches) including the release operation member 15 (release switch 71). Is desirable.

  As described above, the section of the release operation member 15 is formed to have a substantially concave shape toward the inside. As described above, the device of this shape is a device that allows the user (user) to grasp the position of the release operation member 15 with certainty. By setting it as such a shape, the user (user) can grasp | ascertain the position of an operation member reliably, and can perform desired operation correctly. This also avoids the problem of accidentally closing the voice input / output opening or the like with a finger. Therefore, the contrivance of the shape of the release operation member 15 in the present embodiment also contributes to avoiding the problem that the user (user) blocks the voice input / output opening. This also contributes to obtaining an effect that can always be secured.

  Further, since the lens barrel 7 is detachable in the intermediate cylinder 1 with the image sensor, the light receiving surface of the image sensor 11 is exposed to the outside when the lens barrel 7 is removed. Therefore, although not shown in the drawings, the opening is used when the lens barrel 7 is removed from the intermediate cylinder 1 with the image sensor, or when the intermediate cylinder 1 with the image sensor is carried or stored alone. A protective cap for covering 10a and protecting the inside is prepared.

  As described above, according to the one embodiment, the first communication antenna 87a of the first wireless communication unit and the second communication antenna 88a of the second wireless communication unit obstruct wireless input / output of electrical signals. The outer surface is covered with a right side cover 62, an upper cover 60, and a main body 10 that are not formed of a material such as resin mold parts. Therefore, transmission / reception of control signals, image data, and the like by wireless communication can always be performed in a good and stable state.

  Further, the first communication antenna 87a is disposed on the right side surface of the intermediate cylinder 1 with an image sensor at a site near the upper surface and near the back surface, while the second communication antenna 88a is an intermediate with an image sensor. On the upper surface of the cylinder 1, it is disposed at a substantially central portion in the front-rear direction (Z-axis direction) and closer to the right side surface. By adopting such an arrangement, even if both are used at the same time without arranging them at separate positions, the wireless communication does not interfere with each other, and good and stable wireless communication can always be maintained. .

  In addition, the second wireless communication unit is configured to be turned on / off in conjunction with the main power on / off state of the intermediate cylinder 1 with the image sensor, and when the main power of the intermediate cylinder 1 with the image sensor is in the on state, 2 The connection state by the wireless communication unit is always on. According to this, the control of the intermediate cylinder 1 with the image sensor can be performed by another external device that is always in a connected state.

  On the other hand, when the power state of the second wireless communication unit is always on regardless of the main power state of the intermediate cylinder 1 with the image sensor, for example, the intermediate cylinder with the image sensor is controlled by control from another external device. Remote operation including on / off control of the power supply state of the intermediate cylinder 1 with the image sensor can be performed from a position away from 1.

  On the other hand, the pair of microphones 79 for voice acquisition is arranged on the outer surface on the upper surface side of the front frame 66 so as to be disposed in a region near the front surface and between the mount ring 12 and the release switch 71. . By such a device arrangement, it is possible to avoid a situation in which the user (user) blocks the sound input / output opening of the microphone 79 during use of the device, and thus always ensures good sound collection. Will be able to. In addition, since the pair of microphones 79 is disposed in the cylindrical main body 10 using the empty space between the front frame 66 and the main body 10, the enlargement of the intermediate cylinder 1 with the image sensor is suppressed. However, it is possible to obtain an effect that the member arrangement can be performed efficiently.
