Description

Camera device

Technical Field

The present invention relates to a camera device, and more particularly, to a camera device that can extend a lens barrel forward along an optical axis direction.

Background

Conventionally, a camera having a lens barrel extension mechanism that extends a lens barrel forward in an optical axis direction is known (for example, see patent document 1). In order to make a camera having such a lens barrel extension mechanism thin, it is also conceivable to form the lens barrel into a multi-stage nested structure. However, a mechanism for extending the lens barrel in multiple stages in such a nested structure tends to be complicated, and a large storage space is required, which makes it difficult to make the camera thin.

SUMMERY OF THE UTILITY MODEL

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide a compact camera device capable of extending a lens barrel having a nested structure in multiple stages.

The utility model provides a compact camera device of lens barrel that can the multistage stretch out nested structure. The camera device includes: a barrel portion; and a lens barrel movable in an extending direction along the optical axis direction from a retracted state housed inside the barrel portion. The lens barrel includes: a 1 st lens barrel unit which is movable in the extending direction with respect to the barrel portion from a state of being accommodated inside the barrel portion in the radial direction; and a 2 nd barrel unit that is movable in the extension direction with respect to the 1 st barrel unit from a state of being accommodated inside the 1 st barrel unit in the radial direction. The 2 nd barrel unit has an engaging portion provided on the 1 st barrel unit side. The 1 st lens barrel unit described above includes: a base portion; a lens barrel unit biasing portion provided on the base portion and biasing the 2 nd lens barrel unit in the extending direction; and a working lever provided on the base portion so as to be rotatable about a rotation axis. The operating lever includes an operating portion protruding outward in a radial direction of the base portion and a locking portion that engages with the engaging portion of the 2 nd barrel unit by rotating in a locking direction about the rotation axis; the 1 st barrel unit includes a lever biasing portion that biases the operating lever in the locking direction. The barrel portion has a 1 st abutting portion which abuts against the operating portion of the operating lever when the 1 st barrel unit moves in the extending direction with respect to the barrel portion, and rotates the operating lever in a direction opposite to the locking direction.

According to such a configuration, when the lens barrel is in the collapsed state, the locking portion of the operating lever is engaged with the engaging portion of the 2 nd barrel unit by the lever urging portion of the 1 st barrel unit, and therefore the 1 st barrel unit and the 2 nd barrel unit move integrally in the extending direction, but while the lens barrel is extending from the collapsed state, the operating lever rotates in the direction opposite to the locking direction due to the operating portion of the operating lever coming into contact with the 1 st abutting portion of the barrel portion, and the locking portion of the operating lever is disengaged from the engaging portion of the 2 nd barrel unit. Since the 2 nd barrel unit is biased in the extension direction by the barrel unit biasing portion of the 1 st barrel unit, when the locking portion of the operating lever is disengaged from the engaging portion of the 2 nd barrel unit, the 2 nd barrel unit moves in the extension direction with respect to the 1 st barrel unit. Thus, according to the structure of the present invention, the lens barrel of the nested structure can be extended in the extending direction in two stages by a simple and compact structure, and the camera device can be further thinned.

The lens barrel may include a movement restricting portion that restricts movement of the 2 nd barrel unit in the extending direction with respect to the 1 st barrel unit within a certain range. The 1 st barrel unit may further include a rotation restricting portion that restricts rotation of the operating lever in the locking direction. Further, the locking portion of the operating lever may have an inclined surface capable of guiding the engaging portion of the 2 nd barrel unit. Further, the engaging portion of the 2 nd barrel unit may have an inclined surface capable of guiding the locking portion of the operating lever. In addition, the locking portion of the operating lever preferably has an elastically deformable folded shape.

The operating portion of the operating lever may be formed by a groove formed in the barrel portion so as to protrude radially outward from the groove. In this case, the 1 st contact portion may be formed by an edge portion of the groove portion extending in a direction perpendicular to the extending direction.

The barrel portion preferably includes a 2 nd abutting portion which abuts against the operating portion of the operating lever to rotate the operating lever in the locking direction when the operating portion of the operating lever is not rotated in the locking direction by the biasing force of the lever biasing portion when the operating portion is separated from the 1 st abutting portion of the barrel portion. In this case, the operating portion of the operating lever may protrude radially outward from a groove formed in the barrel portion, and the 2 nd contact portion may be formed by an edge portion of the groove extending obliquely with respect to the extending direction.

According to the present invention, when the lens barrel is in the collapsed state, the locking portion of the operating lever is engaged with the engaging portion of the 2 nd lens barrel unit through the lever urging portion of the 1 st lens barrel unit, and therefore the 1 st lens barrel unit and the 2 nd lens barrel unit move integrally in the extending direction, but in the midway when the lens barrel extends from the collapsed state, the operating lever rotates in the direction opposite to the locking direction due to the abutting of the operating portion of the operating lever and the 1 st abutting portion of the barrel portion, so that the locking portion of the operating lever is disengaged from the engaging portion of the 2 nd lens barrel unit. Since the 2 nd barrel unit is biased in the extension direction by the barrel unit biasing portion of the 1 st barrel unit, when the locking portion of the operating lever is disengaged from the engaging portion of the 2 nd barrel unit, the 2 nd barrel unit moves in the extension direction with respect to the 1 st barrel unit. Thus, according to the structure of the present invention, the lens barrel of the nested structure can be extended in the extending direction in two stages by a simple and compact structure, and the camera device can be further thinned.

Detailed Description

Hereinafter, an embodiment of a camera device according to the present invention will be described in detail with reference to fig. 1 to 11. In fig. 1 to 11, the same or corresponding components are denoted by the same reference numerals, and redundant description thereof is omitted. In fig. 1 to 11, the scale and size of each component may be exaggerated or some components may be omitted.

Fig. 1 is a perspective view showing a camera device 1 according to an embodiment of the present invention. The camera device 1 in the present embodiment is a camera (live camera) using a photographic film which is automatically developed after taking a picture, but the present invention can be applied to a camera other than such a live camera. In the present embodiment, for convenience, the + X direction in fig. 1 is referred to as "front" or "front", and the-X direction is referred to as "rear" or "rear".

As shown in fig. 1, the camera apparatus 1 has a front cover 2, a rear cover 3 mounted behind the front cover 2, and a top cover 4 sandwiched between the front cover 2 and the rear cover 3. A finder window 5 is formed in the front cover 2, and a flash window 6 is disposed adjacent to the finder window 5. Further, a release button 7 is disposed on the-Z direction side of the finder window 5. A discharge slit 4A extending in the Y direction is formed in the top cover 4, and a photographic film developed after photographing is discharged from the discharge slit 4A.

Fig. 2 is an exploded perspective view showing a part of the components housed in the internal space formed by the front cover 2, the rear cover 3, and the top cover 4. As shown in fig. 2, the camera device 1 includes a lens barrel 10 housed inside a cylindrical portion 2A (see fig. 1) of the front cover 2, and a frame 20 to which the lens barrel 10 is attached. The frame 20 includes a base portion 21 having a substantially rectangular parallelepiped shape and a cylindrical barrel portion 22 extending forward from the base portion 21 and holding the lens barrel 10.

The lens barrel 10 in the present embodiment has a structure that can be extended in the + X direction. Fig. 3 is a perspective view showing the lens barrel 10 in a state of being maximally extended in the + X direction. As shown in fig. 3, the lens barrel 10 includes a 1 st cylinder portion 11, a 2 nd cylinder portion 12, and a 3 rd cylinder portion 13. The 1 st tubular portion 11 is movable in the X direction with respect to the tubular portion 22 of the frame 20, and the 2 nd tubular portion 12 is movable in the X direction with respect to the 1 st tubular portion 11. Further, the 3 rd cylinder portion 13 is movable in the X direction with respect to the 2 nd cylinder portion 12. In the present embodiment, the 1 st tube part 11 constitutes the rear barrel unit 31 (the 1 st barrel unit), and the 2 nd tube parts 12 and 13 constitute the front barrel unit 32 (the 2 nd barrel unit).

As shown in fig. 3, two engaging projections 14 projecting outward in the radial direction are formed at the rear end portion of the 1 st tube portion 11 of the lens barrel 10. As shown in fig. 2, two guide grooves 24 extending in the direction of the optical axis P (X direction) are formed in the barrel portion 22 of the frame 20 corresponding to the respective engaging projections 14. The engaging projections 14 of the lens barrel 10 are housed inside the guide grooves 24 of the barrel 22 and engage with the guide grooves 24. The width of the guide groove 24 in the Z direction is slightly larger than the width of the engaging projection 14 in the Z direction. Therefore, the engaging projection 14 moves in the direction of the optical axis P (X direction) inside the guide groove 24 while being guided by the guide groove 24.

As shown in fig. 2, the operation button 8 is provided in the vicinity of the barrel portion 22 of the frame 20 in a state of being biased in the + X direction by the coil spring 8A. As shown in fig. 1, the operation button 8 protrudes from the front cover 2 in the + X direction near the cylindrical portion 2A of the front cover 2, and the user pushes the operation button 8 in the-X direction. When the user presses the operation button 8 in the-X direction, the engaging protrusion 14 of the lens barrel 10 is pushed out in the + X direction by the barrel extension mechanism 9 mounted on the barrel portion 22, so that the lens barrel 10 extends in the + X direction (extending direction) as shown in fig. 4. When the lens barrel 10 flies out from the barrel portion 22 in the + X direction, the power supply of the camera apparatus 1 is turned on by a not-shown switch mechanism.

The lens barrel extension mechanism 9 includes: a lever 9A which pushes out the engaging projection 14 in the + X direction in conjunction with the operation button 8; and a torsion coil spring (not shown) whose direction of urging the engaging projection 14 is reversed according to the position of the engaging projection 14. The torsion coil spring is constituted by: when the engaging projection 14 moves in the + X direction beyond a predetermined position, the engaging projection 14 is biased in the + X direction, whereas when the engaging projection 14 moves in the-X direction beyond a predetermined position, the engaging projection 14 is biased in the-X direction. In addition, the barrel extending mechanism 9 is not limited to a specific mechanism, and may be of any configuration as long as the lens barrel 10 can be extended in the + X direction.

In the present embodiment, the front barrel unit 32 moves (extends) in the + X direction with respect to the rear barrel unit 31 as shown in fig. 4 while the lens barrel 10 moves in the + X direction with respect to the barrel portion 22. In the present embodiment, in the state shown in fig. 4, the user can further pull out the 3 rd tubular portion 13 from the 2 nd tubular portion 12 in the + X direction by hand. Fig. 1 shows a state in which the lens barrel 10 is housed in the barrel portion 22 of the frame 20, in which state the lens barrel 10 is shortest in the X direction. This state will be referred to as "contracted state" hereinafter.

Fig. 5 is an exploded perspective view of the lens barrel 10. Fig. 6 is a schematic conceptual diagram showing the mutual relationship of the components of the lens barrel 10 in the collapsed state, and the components are simplified and schematically shown for easy understanding. In fig. 6, the 2 nd barrel section 12 and the 3 rd barrel section 13 are shown as the front barrel unit 32 without distinction from each other.

As shown in fig. 5, the 2 nd tube portion 12 of the front barrel unit 32 includes a cylindrical portion 71 and three protrusions 72 protruding outward in the radial direction from the-X-direction-side end portion of the cylindrical portion 71. Further, the 3 rd barrel portion 13 of the front barrel unit 32 includes: a cylindrical portion 61 housed inside the cylindrical portion 71 of the 2 nd cylindrical portion 12; a flange portion 62 that extends radially outward from the distal end of the cylindrical portion 61; and a base portion 63 having a rectangular opening S1 formed at the center thereof. Two engaging portions 64 extending in the-X direction are formed on the rear barrel unit 31 side of the base portion 63. Each of the engaging portions 64 has a triangular prism-shaped claw portion 65 at a distal end portion.

The rear barrel unit 31 includes: a base portion 40 having a rectangular opening S2 formed at the center thereof; and a cylindrical portion 41 extending from the base portion 40 in the + X direction. The engaging projection 14 extends radially outward from the base portion 40. Three guide grooves 45 extending in the X direction are formed in the inner peripheral surface of the cylindrical portion 41 so as to correspond to the three protrusions 72 of the front barrel unit 32. Each protrusion 72 of the front barrel unit 32 is housed inside the guide groove 45 of the cylindrical portion 41 of the rear barrel unit 31, and engages with the guide groove 45. The circumferential width of the guide groove 45 is slightly larger than the circumferential width of the protrusion 72. Therefore, the projection 72 moves in the X direction inside the guide groove 45 while being guided by the guide groove 45.

Fig. 7 is an exploded perspective view of the rear barrel unit 31 of the lens barrel 10. As shown in fig. 7, the rear barrel unit 31 includes two work levers 42 attached to the base portion 40 and two push-out levers 43 attached to the base portion 40. The two operating levers 42 are disposed at positions symmetrical with respect to the center of the base portion 40, and the push-out lever 43 is also disposed at positions symmetrical with respect to the center of the base portion 40.

Fig. 8 is a perspective view showing the work lever 42. As shown in fig. 8, the operating lever 42 is attached to a shaft portion 46 (see fig. 7) of the base portion 40, and is configured to be rotatable about the shaft portion 46. The work lever 42 has: a base portion 51 having a shaft hole 50 into which the shaft portion 46 of the base portion 40 is inserted; a working portion 52 extending from the base portion 51 in the + Z direction; a lock portion 53 formed on the + X direction side of the base portion 51; and a spring receiving portion 54 extending from the root portion of the lock portion 53 in the + Z direction. The length of the working portion 52 in the Z direction is such that, when the working lever 42 is attached to the base portion 40, the working portion 52 projects radially outward from the base portion 40 as shown in fig. 5.

As shown in fig. 6 and 7, one arm portion 55A of the torsion coil spring 55 engages with the spring receiving portion 54 of the operating lever 42. The coil portion 55B of the torsion coil spring 55 is disposed around the shaft portion 46 of the base portion 40, and the other arm portion 55C engages with the wall portion 40A of the base portion 40. The torsion coil spring 55 is mounted such that the opening angle between the arm portions 55A, 55C is smaller than the free angle of the torsion coil spring 55. Therefore, the operating lever 42 is biased counterclockwise about the rotation axis J shown in fig. 8. Hereinafter, a direction in which the operating lever 42 is urged by the torsion coil spring 55, that is, a direction in which the operating lever rotates counterclockwise about the rotation axis J in fig. 8 is referred to as a "locking direction", and a direction in which the operating lever rotates clockwise about the rotation axis J is referred to as an "unlocking direction". As described above, the torsion coil spring 55 in the present embodiment functions as a lever biasing portion that biases the operating lever 42 in the locking direction.

As shown in fig. 8, the lock portion 53 of the operating lever 42 extends in the + X direction from the base portion 51, and then turns back in the-X direction to extend. By such a folded shape, the lock portion 53 is elastically deformed in the Y direction. The locking portion 53 has a triangular prism-shaped claw portion 56 at the distal end portion. As shown in fig. 6, in the collapsed state, the claw portion 56 of the lock portion 53 of the operating lever 42 engages with the claw portion 65 of the engaging portion 64 of the front barrel unit 32.

As described above, the operating portion 52 of the operating lever 42 protrudes radially outward from the base portion 40, but as shown in fig. 2, the groove portion 25 extending in the X direction is formed in the barrel portion 22 corresponding to the operating portion 52 of the operating lever 42. The operating portion 52 of the operating lever 42 protrudes radially outward from the groove portion 25 via the groove portion 25. When the lens barrel 10 is extended in the + X direction, the working portion 52 of the working lever 42 moves inside the groove of the barrel portion 22.

Fig. 9 is a perspective view showing the push-out lever 43. As shown in fig. 9, the push-out lever 43 includes: a base 81 having a shaft hole 80 into which a shaft 47 (see fig. 7) attached to the base 40 is inserted; an arm portion 82 extending from the base portion 81 in the substantially + Z direction; a pushing portion 83 provided at the tip of the arm portion 82; and a spring receiving portion 84 formed on the arm portion 82.

As shown in fig. 6 and 7, one arm portion 85A of the torsion coil spring 85 engages with the spring receiving portion 84 of the push-out lever 43. The coil portion 85B of the torsion coil spring 85 is disposed around the base portion 81 of the push-out lever 43, and the other arm portion 85C engages with the surface of the base portion 40. The torsion coil spring 85 is mounted such that the opening angle between the arm portions 85A, 85C is smaller than the free angle of the torsion coil spring 85. Therefore, the push-out lever 43 is biased counterclockwise about the rotation axis K shown in fig. 9.

As shown in fig. 6, the pushing portion 83 of the push-out lever 43 biased by the torsion coil spring 85 abuts against the rear end surface 32A of the front barrel unit 32 (for example, the rear end surface 12A of the 2 nd barrel portion 12 shown in fig. 5), and the push-out lever 43 pushes the front barrel unit 32 in the + X direction (extending direction). That is, the push-out lever 43 and the torsion coil spring 85 constitute a barrel unit biasing portion that biases the front barrel unit 32 in the + X direction.

In the collapsed state shown in fig. 6, as described above, the claw portion 65 of the engaging portion 64 of the front barrel unit 32 and the claw portion 56 of the locking portion 53 of the rear barrel unit 31 are engaged with each other, and therefore the front barrel unit 32 does not move in the + X direction with respect to the rear barrel unit 31.

Fig. 10A to 10F are schematic conceptual views for explaining the extending operation and the retracting operation of the lens barrel 10, and correspond to the schematic conceptual view of fig. 6. As described above, when the user presses the operation button 8 in the-X direction, the engagement projection 14 of the lens barrel 10 is pushed out in the + X direction by the barrel extension mechanism 9 attached to the barrel portion 22, and the lens barrel 10 moves in the + X direction. At this time, as described above, since the claw portion 65 of the engaging portion 64 of the front barrel unit 32 and the claw portion 56 of the locking portion 53 of the operating lever 42 of the rear barrel unit 31 are engaged with each other, the front barrel unit 32 and the rear barrel unit 31 move integrally in the + X direction.

When the front barrel unit 32 and the rear barrel unit 31 move integrally in the + X direction, the operating portion 52 of the operating lever 42 of the rear barrel unit 31 moves in the + X direction within the groove portion 25 of the barrel portion 22, but soon comes into contact with the edge portion 25A of the groove portion 25 of the barrel portion 22 extending in the direction perpendicular to the X direction as shown in fig. 10A. In this state, when the front barrel unit 32 and the rear barrel unit 31 are further moved in the + X direction, the operating portion 52 of the operating lever 42 is pressed in the-X direction by the edge portion 25A of the groove portion 25 of the barrel portion 22. Accordingly, the operating lever 42 is rotated in the unlocking direction (clockwise in fig. 10A) about the shaft portion 46 of the base portion 40 against the urging force of the torsion coil spring 55 as indicated by the arrow in fig. 10A.

When the operating lever 42 is rotated in the unlocking direction in this way, the claw portion 56 of the locking portion 53 of the operating lever 42 is disengaged from the claw portion 65 of the engaging portion 64 of the front barrel unit 32. At this time, since the push-out lever 43 of the rear barrel unit 31 pushes the rear end surface 32A of the front barrel unit 32 in the + X direction by the torsion coil spring 85, when the locking portion 53 of the operating lever 42 is disengaged from the engaging portion 64 of the front barrel unit 32, the front barrel unit 32 is pushed out in the + X direction by the push-out lever 43 as shown in fig. 10B. Thereby, the front barrel unit 32 is extended in the + X direction with respect to the rear barrel unit 31.

At this time, as shown in fig. 10B, the protrusion 72 of the front barrel unit 32 abuts against the + X-direction edge 45A of the guide groove 45 of the rear barrel unit 31, thereby restricting the + X-direction movement of the front barrel unit 32 with respect to the rear barrel unit 31. In this way, the guide groove 45 of the cylindrical portion 41 of the rear barrel unit 31 and the protrusion 72 of the front barrel unit 32 function as a movement restricting portion that restricts movement of the front barrel unit 32 relative to the rear barrel unit 31 within a certain range. It is needless to say that the similar movement restricting portion may be configured by forming a protrusion on rear barrel unit 31 and a guide groove on front barrel unit 32.

As described above, the edge 25A of the groove 25 of the barrel 22 in the present embodiment functions as the 1 st contact portion that comes into contact with the operating portion 52 of the operating lever 42 and rotates the operating lever 42 in the unlocking direction when the rear barrel unit 31 moves in the + X direction with respect to the barrel 22. Such an abutting portion is not limited to the edge portion 25A of the groove portion 25, and the 1 st abutting portion may be formed of a wall formed on the inner side of the tub portion 22, for example.

On the other hand, as shown in fig. 10B, in order to convert the front barrel unit 32 and the rear barrel unit 31 from the extended state in the + X direction to the retracted state, the user presses the front barrel unit 32 (for example, the flange portion 62 of the 3 rd barrel portion 13) in the-X direction, for example. At this time, the user needs to push the front barrel unit 32 in the-X direction against the urging force of the torsion coil spring 85 that urges the push-out lever 43. When the front barrel unit 32 is pushed in the-X direction, as shown in fig. 10C, first, the front barrel unit 32 moves in the-X direction with respect to the rear barrel unit 31.

When the user further pushes the front barrel unit 32 in the-X direction from the state shown in fig. 10C, the flange portion 62 of the 3 rd cylindrical portion 13 of the front barrel unit 32 abuts on the front end of the cylindrical portion 41 of the rear barrel unit 31. The rear barrel unit 31 also moves in the-X direction together with the front barrel unit 32. Accordingly, as shown in fig. 10D, the operating portion 52 of the operating lever 42 is separated from the edge portion 25A of the groove portion 25 of the tub portion 22. Thus, the operating lever 42 is rotated in the locking direction by the biasing force of the torsion coil spring 55, and the claw portion 56 of the locking portion 53 is engaged with the claw portion 65 of the engaging portion 64 of the front barrel unit 32. At this time, as shown in fig. 10D, the operating portion 52 of the operating lever 42 abuts against the rear end surface 40B of the base portion 40, thereby restricting the rotation of the operating lever 42 in the locking direction. As described above, in the present embodiment, the rear end surface 40B of the base portion 40 of the rear barrel unit 31 functions as a rotation restricting portion that restricts the rotation of the operating lever 42 in the lock direction.

When the user presses the front barrel unit 32 and the rear barrel unit 31 in the-X direction by a predetermined distance or more, the direction in which the barrel extension mechanism 9 applies force to the engaging projection 14 of the rear barrel unit 31 is reversed as described above, and the engaging projection 14 of the rear barrel unit 31 is biased in the-X direction by the barrel extension mechanism 9. Therefore, even if the user takes the hand away from the front barrel unit 32, the rear barrel unit 31 continues to move in the-X direction. At this time, since the claw portion 56 of the locking portion 53 of the operating lever 42 of the rear barrel unit 31 is engaged with the claw portion 65 of the engaging portion 64 of the front barrel unit 32, the front barrel unit 32 also moves in the-X direction together with the rear barrel unit 31, and the lens barrel 10 is in the collapsed state as shown in fig. 1.

The above-described retracting operation is explained on the assumption that the front barrel unit 32 is first moved in the-X direction, but when the rear barrel unit 31 is first moved in the-X direction, as shown in fig. 10E, the operating portion 52 of the operating lever 42 is separated from the edge portion 25A of the groove portion 25 of the barrel portion 22, and therefore the operating lever 42 is rotated in the locking direction by the biasing force of the torsion coil spring 55 before the claw portion 65 of the engaging portion 64 of the front barrel unit 32 is moved to a position where it can engage with the claw portion 56 of the locking portion 53 of the operating lever 42. Even in such a case, according to the present embodiment, the lens barrel 10 can be in the collapsed state.

That is, as shown in fig. 10E, the triangular prism-shaped claw portion 56 of the locking portion 53 of the operating lever 42 has an inclined surface 56A capable of guiding the claw portion 65 of the engaging portion 64 of the front barrel unit 32. The triangular prism-shaped claw portion 65 of the engaging portion 64 of the front barrel unit 32 has an inclined surface 65A capable of guiding the claw portion 56 of the locking portion 53 of the operating lever 42. Therefore, when the front barrel unit 32 is pushed in the-X direction in the state shown in fig. 10E, the inclined surface 56A of the claw portion 56 of the lock portion 53 and the inclined surface 65A of the claw portion 65 of the engagement portion 64 slide on each other, and the lock portion 53 and the engagement portion 64 elastically deform and engage with each other beyond the claw portions 56 and 65. In particular, in the present embodiment, since the lock portion 53 of the operating lever 42 has the folded shape as described above, it is easily elastically deformed, and the claw portion 56 of the lock portion 53 can be easily engaged with the claw portion 65 of the engaging portion 64. In this way, when the claw portion 56 of the lock portion 53 is engaged with the claw portion 65 of the engagement portion 64, the state shown in fig. 10D is obtained, and therefore, the lens barrel 10 can be brought into the collapsed state by the above-described operation.

In the above-described retracting operation, when the torsion coil spring 55 does not bias the operating lever 42 in the locking direction for some reason, it is considered that the claw portion 56 of the locking portion 53 of the operating lever 42 cannot be engaged with the claw portion 65 of the engaging portion 64, and the lens barrel 10 cannot be brought into the retracted state. In the present embodiment, in order to cope with such a problem, as shown in fig. 2, a rim portion 25B extending obliquely to the X direction is formed in the groove portion 25 of the tub portion 22.

That is, when the user further pushes the front barrel unit 32 in the-X direction from the state shown in fig. 10C, the operating lever 42 moves in the-X direction while being kept not rotated in the locking direction in a case where the biasing force of the torsion coil spring 55 does not act on the operating lever 42, and at this time, as shown in fig. 10F, the edge portion 25B of the groove portion 25 of the barrel portion 22 abuts against the operating portion 52 of the operating lever 42. Then, as the operating lever 42 moves in the-X direction, the operating portion 52 of the operating lever 42 is guided by the edge portion 25B of the groove portion 25, and the operating lever 42 rotates in the locking direction. Thereby, the claw portion 56 of the lock portion 53 can be engaged with the claw portion 65 of the engagement portion 64. In this way, the edge 25B of the groove 25 of the barrel 22 in the present embodiment functions as the 2 nd contact portion that contacts the operating portion 52 of the operating lever 42 and rotates the operating lever 42 in the lock direction. Such an abutting portion is not limited to the edge portion 25B of the groove portion 25, and the 2 nd abutting portion may be formed by a wall formed on the inner side of the tub portion 22, for example.

In the above example, the lock portion 53 of the operating lever 42 has a U-shaped folded shape, but such a folded shape is not necessarily required. Therefore, for example, instead of the above-described operating rod 42, an operating rod 142 having a locking portion 153 extending from the base portion 51 without being folded back may be used as shown in fig. 11. However, in order to facilitate elastic deformation of the lock portion when the contraction operation is performed from the state shown in fig. 10E, it is preferable to use a lock portion 53 having a U-shaped folded shape.

The terms "front", "rear", "upper", "lower" and the terms indicating other positional relationships used in the present specification are used in association with the illustrated embodiments, and vary depending on the relative positional relationship of the devices.

The preferred embodiments of the present invention have been described above, but the present invention is not limited to the above embodiments, and can be implemented in various different forms within the scope of the technical idea thereof.
