(First embodiment)
An attachment and an endoscope system according to a first embodiment of the present invention will be described with reference to FIGS. FIG. 1 is an overall view showing an endoscope apparatus in an endoscope system. FIG. 2 is a perspective view of the endoscope system, and is an enlarged view of the attachment.
As shown in FIG.1 and FIG.2, the endoscope system of this embodiment is a system provided with the endoscope apparatus 100 and attachment A1.
The endoscope apparatus 100 includes an insertion pipe P that is inserted into an object to be observed, an imaging mechanism 101 that is positioned at the tip of the insertion pipe P, and a curve provided between the imaging mechanism 101 and the insertion pipe P. Part 102 and an operation part 103 provided at the proximal end of the insertion pipe P.

The imaging mechanism 101 includes an image sensor such as a CCD or a CMOS, for example, and acquires an image of an observation target.
The bending portion 102 has a known cylindrical structure to which the tips of a plurality of wires W are connected and bends when the wires W are pulled. A wire W for bending the bending portion 102 is disposed in the insertion pipe P. The proximal end of the wire W is disposed in the operation unit 103.

  As shown in FIGS. 1 and 2, the operation unit 103 includes an operation unit main body 1 that constitutes a casing of the operation unit 103, a bearing 2 installed in the operation unit main body 1, and a joystick attached to the bearing 2. (Operation member) 3.

  The bearing 2 is a member that supports the joystick 3 so that the joystick 3 can freely rotate about the swing point R as the center of swing. The bearing 2 is provided with a pulling arm 4 connected to the proximal end of the wire W.

  As shown in FIG. 2, the joystick 3 is provided so as to be rotatable about axes a and b that pass through the swing point R and are orthogonal to each other. Furthermore, a knob 5 is fixed to the upper end portion of the joystick 3 (the end portion opposite to the end portion attached to the bearing 2). The joystick 3 is tilted around the swing point R while the operator holds the knob 5.

  The pulling arm 4 is formed in a disc shape as a whole, and has four protrusions 4A provided at 90 ° intervals at positions corresponding to the axes a and b with the axis of the joystick 3 as the center. The Each protrusion 4A is connected to a wire W, and is tilted from the neutral position of the joystick 3 (operations about the axes a and b shown in FIG. 2; the directions of arrows a1-a2 and arrows b1-b2). The traction arm 4 swings along with this. Thereby, any wire W of the protruding portion 4A is pulled, and the traction force of any wire W is released. As a result, the bending portion 102 connected to the wire W can be bent.

  The knob 5 is formed in a substantially hemispherical shape capable of pressing an operator's finger or the like, for example. The knob 5 is formed with a recess 5A that engages with a knob core 15 described later.

  By bending the bending portion 102 via the wire W by the operation portion 103, the orientation of the imaging mechanism 101 located at the distal end of the bending portion 102 can be freely changed. Further, the operating force at the operation unit 103 is transmitted to the bending unit 102 via a wire pulling mechanism (not shown).

FIG. 3 is a perspective view showing the entire attachment A1. FIG. 4 is a cross-sectional view showing a connection state between the attachment and the joystick.
The attachment A1 can be detachably attached to the operation unit 103 of the endoscope apparatus 100 shown in FIG. 1 (see FIG. 6). The attachment A1 includes a frame (elastic member) 10, a lock knob (connecting portion) 12 attached to the frame 10, and a pair of contact members (first and second contact members) 13 provided at both ends of the frame 10. To do.

  As shown in FIGS. 2 and 3, the frame 10 is a long body formed in an arc shape by an elastic member. An intermediate portion of the frame 10 formed in an arc shape has a curvature that matches the movement locus c <b> 1-c <b> 2 of the protruding end 3 </ b> A of the joystick 3. Since the frame 10 is made of an elastically deformable material, a slight difference in curvature can be absorbed by elastic deformation. A slide hole 11 is formed in the frame 10 along the length direction of the frame 10. The slide hole 11 is formed so as to coincide with the movement trajectory of the joystick 3 (indicated by arrows c <b> 1-c <b> 2), and the inner peripheral surface of the slide hole 11 serves as a guide wall portion 14 that guides the lock knob 12.

  Both ends of the slide hole 11 in the length direction of the frame 10 are formed to be slightly wider than the intermediate portion. In the present embodiment, the width dimension of the intermediate portion of the slide hole 11 in the length direction of the frame 10 is such that the guide wall portion 14 is slidably in contact with the lock knob 12.

As shown in FIG. 4, the lock knob 12 is provided on the guide wall portion 14 of the slide hole 11 so as to have a sliding resistance. The lock knob 12 is provided with a knob core 15 that engages with the knob 5.
The knob core 15 is provided with a convex portion (engagement portion) 15A that protrudes so as to engage with the protruding end of the knob 5. The convex portion 15 </ b> A formed on the knob core 15 is inserted into a concave portion (engaging portion) 5 </ b> A formed on the protruding end of the knob 5. The lock knob 12 is moved integrally with the joystick 3 in a state where the convex portion 15A is engaged in the concave portion (engaging portion) 5A of the knob 5.

Next, a pair of contact members (first and second contact members) 13 provided at each end of the frame 10 of the attachment A1 will be described. Since these contact members 13 have the same basic configuration, only one of them will be described.
FIG. 5 is a cross-sectional view showing a contact state between the attachment and the operation unit.
As shown in FIG. 5, the contact member 13 includes a lock main body 21 and a rubber sheet (high friction member) 29 interposed between the lock main body 21 and the frame 10. In the present embodiment, the contact member 13 is formed with a support portion 13 </ b> A on the side of the lock body 21.

  The lock body 21 is a contact surface that contacts one of a pair of surfaces (hereinafter referred to as contacted surfaces M1) that are directed substantially opposite to each other on the outer surface of the operation unit body 1 of the endoscope apparatus 100. Abutting portion) 20. Furthermore, the lock body 21 is provided with a protrusion 22 that extends from the contact surface 20 in a direction that intersects the surface direction of the contacted surface M1. As a result, the lock body 21 has an inverted L shape as a whole in cross-sectional shape.

The protruding portion 22 is provided with a pressing surface (pressing portion) 23 that comes into contact with a contacted surface (indicated by reference numeral M2) at a position different from the pair of contacted surfaces M1 of the outer surface of the operation unit main body 1. .
Then, the contact member 13 comes into contact with the contacted surfaces M1 and M2 on the outer surface of the endoscope apparatus 100 through the contact surface 20 and the pressing surface 23 arranged so as to cross each other. Press.

  13 A of support parts are either the contacted surface M1 with which the contact surface 20 of the lock main body 21 contacts, and the contacted surface M2 with which the pressing surface 23 of the protrusion part 22 contacts among the outer surfaces of the operation part main body 1 of the operation part 103. In addition, it is arranged so as to be in contact with another contacted surface (indicated by reference numeral M4 in FIG. 1) extending in a different direction. Although various locations are assumed for the contacted surface M4, in this example, as shown in FIG. 1, the outer surface of the monitor 104 located on the upper rear side of the operation unit 103 is the contacted surface M4.

  As shown in FIG. 5, the contact member 13 is provided with a lock mechanism 90 for the purpose of holding the position of the frame 10 with respect to the contact member 13. The lock mechanism 90 includes a fixing screw 25, a set screw 26 screwed to the fixing screw 25, and a flat washer 27 interposed between the set screw 26 and the outer surface of the frame 10.

The fixing screw 25 is press-fitted into the mounting hole 21 </ b> A of the lock body 21. An engaging pin 24 is provided at the tip of the fixing screw 25. The rear end of the fixing screw 25 has a female screw shape.
The fixing screw 25 passes through the mounting hole 10 </ b> A of the frame 10 and the mounting hole 21 </ b> A of the lock body 21. Thereby, the lock main body 21 is rotatable with respect to the frame 10 around the axis 24 </ b> A of the fixing screw 25 and the engagement pin 24.
The engaging pin 24 at the tip of the fixing screw 25 is formed in a cylindrical shape along the axis 24A. The engagement pin 24 is engaged with the recess 28 of the operation unit body 1 when the contact member 13 of the attachment A1 is attached to the contacted surfaces M1 and M2 of the operation unit body 1. As a result, the engaging pin 24 positions and fixes the attachment A1.

  The set screw 26 has a male screw shape that is screwed into the female screw portion at the rear end of the fixing screw 25, and is disposed so as to contact the outer surface of the frame 10.

  The flat washer 27 has a role of bringing the lock body 21 into close contact with the inner surface of the frame 10 by urging the set screw 26 in a direction away from the outer surface of the frame 10.

  The rubber sheet 29 is formed in an annular shape that is coaxial with the fixing screw 25 and through which the fixing screw passes. The rubber sheet 29 is pressed against the lock body 21 and the frame 10 when the frame 10 is pressed toward the lock body 21 by the urging force of the flat washer 27. By screwing the set screw 26 into the fixing screw 25, the rubber sheet 29 is tightened, and the magnitude of the frictional force between the lock body 21 and the frame 10 and the rubber sheet 29 changes.

  Although details will be described later, the frame 10 rotates about the axis 24 </ b> A with respect to the lock body 21 in accordance with the operation of the joystick 3 in a state where the lock knob 12 and the joystick 3 are connected. At this time, the magnitude of the force required to rotate the lock body 21 and the frame 10 by appropriately adjusting the magnitude of the frictional force between the lock body 21 and the frame 10 and the rubber sheet 29. Can be set.

Next, the usage method and operation of the attachment A1 according to this embodiment will be described. FIG. 6 is a perspective view showing an operation when the attachment is attached to and detached from the joystick.
As shown in FIGS. 1 and 6, in the endoscope apparatus 100, a depression 28 into which the engagement pin 24 can be inserted is formed in the operation unit 103 so that the attachment A1 can be suitably attached. .

  Assume that the operator desires to hold a specific position and angle (the arrangement direction at this time is indicated by arrows (A) to (B)) while operating the joystick 3 of the endoscope apparatus 100. In this case, as shown by an arrow (c) in FIG. 6, the operator grasps the pair of contact members 13 of the attachment A1 by hand, and makes the contact members 13 separated from each other in a natural state. Then, the operator brings the contact surface 20 and the pressing surface 23 of each contact member 13 into contact with the contacted surfaces M1 and M2 on the outer surface of the operation unit main body 1, respectively. Further, the operator releases the hand in a state where the engaging pin 24 at the tip of the fixing screw 25 is engaged with the recess 28 of the operation unit main body 1. Accordingly, the pair of contact members 13 are fixed to the operation unit main body 1 so as to sandwich the operation unit main body 1 of the operation unit 103 of the endoscope apparatus 100.

  At this time, the support portion 13A comes into contact with the contacted portion M4 (the outer surface of the monitor 104). Furthermore, the axis 24A (predetermined one axis) of the engagement pin 24 coincides with one of the straight lines passing through the swing point R when the joystick 3 is tilted (the axis indicated by x in FIG. 2).

  Further, when attaching the contact member 13 to the operation unit main body 1, as shown in FIGS. 2 and 6, the inclination of the frame 10 is adjusted around the axis 24A. Further, the lock knob 12 on the frame 10 is previously positioned along the slide hole 11 so as to coincide with the position of the protruding end 3 </ b> A of the joystick 3.

  Thereafter, simultaneously with the attachment of the contact member 13 to the operation section main body 1, the lock knob 12 is moved together with the frame 10 in the direction of the arrow (A), and is fitted to the knob 5 provided at the protruding end 3 </ b> A of the joystick 3. At this time, the lock knob 12 and the knob 5 are united by moving the convex portion 15A of the knob core 15 located in the lock knob 12 in the arrow (A) direction and fitting the concave portion 5A of the knob 5 into the concave portion 5A. . Further, since the lock knob 12 and the frame 10 are installed so as to have sliding resistance, the joystick 3 is held in an inclined state against the force that the protruding end 3A of the joystick 3 tries to return to the neutral position. The

  That is, in the attachment A1, the joystick 3 is held in an inclined state by fitting the lock knob 12 on the frame 10 and the knob 5 at the protruding end 3A of the joystick 3. Further, in this state, in the attachment A1, the frame 10 is held on the outer surface of the operation unit main body 1 of the operation unit 103 via the contact members 13 at both ends. As a result, the state of the tilted joystick 3 can be maintained as it is.

  In a state where the attachment A1 is attached to the operation unit 103 of the endoscope apparatus 100, when the operator moves the lock knob 12 with a force exceeding the static frictional force by the rubber sheet 29, the joystick 3 can be tilted. it can. At this time, when the operator releases the hand from the lock knob 12, the joystick 3 is held in the state when the hand is released.

Further, when the endoscope apparatus 100 is used, the endoscope apparatus 100 may be dropped, an external force may be applied to the endoscope apparatus 100, or an external force may be applied to the attachment A1.
In this case, these external forces and the like are transmitted to the attachment A1 attached to the operation unit 103, and the frame 10 of the attachment A1 is elastically deformed.
A part of the frame portion 10 is formed in an arc shape, and the contact member 13 is formed in an inverted L shape by the contact surfaces 20 and the protrusions 22. Therefore, when an external force that opens both ends of the frame portion 10 is applied to the frame 10, each protrusion 22 applies a force from the frame portion 10 so that each protrusion 22 is pressed against the outer surface of the operation unit main body 1. receive. Thereby, the frictional force between the contact member 13 and the operation unit main body 1 is increased, and the attachment A1 is less likely to be detached from the operation unit 103.

  As described above, the attachment A1 of the present embodiment is in contact with the contacted surface M1 that is directed to the lock body 21 of the pair of contact members 13 to which the frame 10 is coupled and substantially opposite to the outer surface of the operation unit 103. A contact surface 20 is provided. Furthermore, the lock body 21 includes a protrusion 22 extending in a direction intersecting the contacted surface M1, and a pressing surface 23 provided on the protrusion 22 and directed to a contacted surface M2 different from the contacted surface M1. , Is provided.

Accordingly, in the pair of contact members 13, the contact surfaces 20 are pressed toward the contacted surfaces M <b> 1 that are directed substantially opposite to each other on the outer surface of the operation unit 103 by the elastic force of the frame 10. At the same time, the pressing surface 23 provided on the protruding portion 22 of the contact member 13 is pressed toward the contacted surface M2 different from the contacted surface M1 of the operation unit 103 by the elastic force of the frame 10. As a result, the contact member 13 comes into close contact with the operation unit 103, and the frame 10 is fixed and held on the operation unit 103 via the contact member 13.
That is, in the attachment A 1, the contact surface 20 of the contact member 13 and the pressing surface 23 of the protruding portion 22 are pressed toward the contacted surfaces M 1 and M 2 of the operation unit 103. Hard to come off.

  In addition, the attachment A1 can be attached to and detached from the operation unit 103 by attachment and removal via the contact member 13. Therefore, it is not necessary to incorporate the lock mechanism 90 in the operation unit 103 as in the conventional case, and as a result, the endoscope system can be reduced in size and weight.

Next, a modification of this embodiment will be described.
(Modification 1-1)
In the above embodiment, the protrusions 22 having the pressing surfaces 23 are provided on the lock main bodies 21 of the pair of contact members 13, but the protrusions 22 may be provided on either one of the contact members 13. Good. Similarly, the contact surface 20 may be provided on any one of the contact members 13.

(Modification 1-2)
Next, another modification of the present embodiment will be described with reference to FIGS. 7 (A) and 7 (B). FIG. 7 is a view showing a modification of the attachment, in which (A) is a normal state, and (B) is a partial cross-sectional view when an external force is applied.
In the said embodiment, although the protrusion part 22 is provided in the upper part of the lock main body 21, the position of the protrusion part 22 is not restricted to this. For example, as shown in FIG. 7A, instead of the protrusion 22, the protrusion 22 ′ is located on the lower side of the lock body 21 (on the side opposite to the position of the protrusion 22 described above and far from the frame 10). ) May be provided. In this case, the protruding portion 22 ′ contacts a lower contacted surface (indicated by a symbol M <b> 3) at a position different from the pair of contacted surfaces M <b> 1 on the outer surface of the operation unit main body 1. With such a configuration, the contacted surface M3 can be pressed by the pressing surface 23 'of the protrusion 22'.

  Then, as shown in FIG. 7A, in the contact member 13 of the attachment A1, the contacted surface M1 of the operation unit body 1 of the operation unit 103 is held by the lock body 21 via the frame 10 in a normal fixed state. Sandwich. Thereby, the contact member 13 generates a contact pressure (indicated by reference sign d1). At this time, the contact member 13 of the attachment A1 is fixed to the operation unit main body 1 by the frictional force between the lock main body 21 generated by the contact pressure d1 and the side surface of the operation unit main body 1.

  Here, as shown in FIG. 7B, it is assumed that an external force is applied downward to the frame 10 of the attachment A1 for some reason. At this time, the external force is transmitted through the frame 10 and may cause a slight displacement in the vicinity of the lock main body 21 as indicated by reference numeral (d). In this case, the lock main body 21 fixed to the frame 10 is tilted according to the deformation of the frame 10, and the contact pressure d1 becomes small and becomes limited. On the other hand, in the protruding portion 22 ′ at the lower part of the lock body 21, the frictional force on the contacted surface M <b> 3 increases due to the contact pressure (indicated by reference sign d <b> 2) on the contacted surface M <b> 3 increased by deformation of the frame 10.

At this time, the pair of contact members 30 sandwich the both outer surfaces of the operation unit main body 1.
As shown in FIG. 10, when the attachment A <b> 2 is attached, the fixing pin 38 resists the urging force of the compression spring 39 and is housed in the fixing screw 36. And the front-end | tip part 38B of the fixing pin 38 slides along the to-be-contacted surface M1.
Thereafter, as shown in FIG. 9, the position of the attachment A <b> 2 is adjusted by the operator so that the distal end portion 38 </ b> B of the fixing pin 38 matches the recess 28 on the outer surface of the operation portion main body 1. When the distal end portion 38B of the fixing pin 38 reaches the position of the recess 28, the distal end portion 38B of the fixing pin 38 is engaged with the recess 28 by the urging force of the compression spring 39. Thus, the contact member 30 is fixed to the contacted surfaces M1 and M2 of the operation unit main body 1.

  Also in the present embodiment, as in the first embodiment, the attachment A2 is configured such that the axis 38A (predetermined one axis) of the distal end portion 38B of the fixing pin 38 in the contact member 13 swings when the joystick 3 is tilted. The position coincides with one of the straight lines passing through the moving point R (see FIG. 2) (the axis indicated by the symbol x in FIG. 2).

Next, the locking structure 92 near the lock knob of the frame 10 will be described.
As shown in FIG. 8, in this embodiment, a slide hole 50 having a different shape is formed instead of the slide hole 11 described in the first embodiment.
The slide hole 50 has a shape in which a plurality of circular holes are continuous along the length direction of the frame 10. A guide wall portion 51 for guiding the lock knob 12 is provided on the inner surface of the slide hole 50 as in the first embodiment. In the present embodiment, the guide wall 51 is composed of a plurality of circular holes. The guide wall portion 51 formed of these circular holes is formed in a size that can be attached to and detached from a step portion formed on the outer periphery of the knob core 52 described later. Note that the slide hole 50 of the frame 10 is arranged so as to coincide with the movement trajectory (indicated by arrows c <b> 1-c <b> 2) of the joystick 3, similarly to the slide hole 11 of the first embodiment.

Further, as shown in FIG. 11, the lock knob 12 is provided with a knob core 52 having a different configuration from the knob core 15 described in the first embodiment. The knob core 52 has a mounting hole 53 that is coaxial with the joystick 3. A push-up spring 54 made of a compression spring is disposed in the attachment hole 53.
The push-up spring 54 is disposed so as to be in contact with the upper surface of the knob 5 installed at the upper end of the joystick 3. The push-up spring 54 is made of an elastic body having a weak spring coefficient enough to push up the lock knob 12 on the frame 10 side in a state where it is in contact with the knob 5.
Further, the knob core 52 is provided with a convex portion (engagement portion) 52A protruding downward, as in the first embodiment. The knob core 52 is engaged with a recess (engagement portion) 5A of the knob 5 fixed to the protruding end 3A of the joystick 3, thereby holding the joystick 3 at a predetermined tilt position.

A step portion 55 is formed on the outer peripheral surface of the knob core 52.

When the frame 10 approaches the joystick 3 side and the knob core 52 is pushed up via the push-up spring 54 as shown in FIG. 11, the stepped portion 55 is one of the circular holes of the slide hole 50 of the frame 10. The dimensions are set to be engaged with each other.

When the knob core 52 is lifted by the urging force of the push-up spring 54, a gap (indicated by reference numeral 56 in FIG. 11) is formed between the convex portion 52A of the knob core 52 and the concave portion 5A of the knob 5. It is formed.
The gap 56 is formed to adjust the engagement position of the step portion 55 of the knob core 52 with respect to the guide wall portion 51 of the slide hole 50. The gap 56 allows the operator to push down the knob core 52 together with the lock knob 12 against the urging force of the push-up spring 54. When the knob core 52 is pushed down, the step portion 55 and the slide hole 50 are disengaged as shown in FIG.
In this state, as shown in FIG. 13, the knob core 52 is moved along the slide hole 50 together with the lock knob 12 in the direction of the arrow c <b> 1-c <b> 2. At this time, when the knob core 52 is sequentially moved through the circular hole of the guide wall 51 (for example, moved to the adjacent circular hole), the tilt angle of the joystick 3 is adjusted via the knob core 52 and the knob 5. Can do.

Next, a method of using the attachment A2 according to this embodiment will be described.
Assume that the operator wishes to maintain a specific position and angle while operating the joystick 3 of the endoscope apparatus 100. At this time, the attachment A2 is attached to the operation unit 103.
When attaching the attachment A2, first, the knob 40 of the attachment A2 is pulled, and the fixing pins 38 are moved in directions in which the fixing pins 38 are separated from each other.
Then, the ring-shaped member 31 of the attachment structure 80 is brought into contact with the surface of the operation unit main body 1 located around the joystick 3. At this time, the contact surface 32 and the pressing surface 35 of each contact member 30 are brought into contact with the contacted surfaces M1 and M2 of the outer surface of the operation unit main body 1, respectively. At the same time, as shown in FIG. 9, the distal end portion 38 </ b> B of the fixing pin 38 is engaged with the recess 28 of the operation unit body 1 while sliding the outer surface of the operation unit body 1, and then the hand is released from the knob 40.
Accordingly, the pair of contact members 30 are fixed to the operation unit main body 1 so as to sandwich the operation unit main body 1 of the operation unit 103 of the endoscope apparatus 100.

  Further, when the contact member 30 is attached to the operation unit main body 1, the inclination of the frame 10 around the axis 38A (see FIG. 9) is adjusted. At that time, the lock knob 12 on the frame 10 is previously positioned along the slide hole 50 so that the position of the lock knob 12 coincides with the position of the protruding end 3 </ b> A of the joystick 3. Thereafter, simultaneously with the attachment of the contact member 30 to the operation unit main body 1, the knob core 52 at the lower part of the lock knob 12 is fitted into the knob 5 provided at the protruding end 3 </ b> A of the joystick 3. Thereby, the attachment A2 fixes the joystick 3 in a specific tilted state.

  At this time, the knob core 52 and the knob 5 in the lock knob 12 are combined by fitting the convex portion 52A of the knob core 52 into the concave portion 5A of the knob 5. Further, since the knob core 52 and the frame 10 are connected via the step portion 55 of the knob core 52, the joystick 3 is tilted against the force of the protruding end 3A of the joystick 3 returning to the neutral position. Retained.

With the attachment A2 attached to the operation unit 103, the operator can move the lock knob 12 to tilt the joystick 3. In this case, first, the operator pushes down the knob core 52 together with the lock knob 12 against the urging force of the push-up spring 54. Then, the engagement between the stepped portion 55 and the slide hole 50 is released by pushing down the knob core 52. In this state, as shown in FIG. 13, the operator moves the knob core 52 together with the lock knob 12 in the direction of the arrow c <b> 1-c <b> 2 along the slide hole 50 to sequentially move the circular holes of the guide wall portion 51. Thereby, the knob core 52 can adjust the tilt angle of the joystick 3 via the knob 5.
Thereafter, when the operator removes his / her finger from the lock knob 12, the lock knob 12 is released. Accordingly, as shown in FIG. 11, the knob core 52 is raised by the urging force of the push-up spring 54, the stepped portion 55 engages with the slide hole 50, and the joystick 3 is fixed again.

  That is, in the attachment A2, the joystick 3 is held in an inclined state by fitting between the knob core 52 provided below the lock knob 12 on the frame 10 and the knob 5 of the protruding end 3A of the joystick 3. In this state, in the attachment A2, the frame 10 is held on the outer surface of the operation unit body 1 of the operation unit 103 via the contact members 30 at both ends. As a result, the state of the tilted joystick 3 can be maintained as it is.

  Even the attachment A2 of the present embodiment has the same effects as the attachment A1 described in the first embodiment.

  Moreover, in this embodiment, since a pair of contact member 30 is continued by the ring-shaped member 31, each contact member 30 is the frame 10 and the ring-shaped member 31 which connect each contact member 30 in a different path | route. Are held by both. As a result, the attachment A2 is less twisted when an external force is applied to the attachment A2, and the possibility that the attachment A2 is detached from the operation unit 103 can be further reduced.

  Furthermore, in this embodiment, the guide wall part 51 formed in the frame 10 has a shape in which circular holes are continuous, and the lock knob 12 engages with each circular hole. In this embodiment, when the lock knob 12 is moved along the guide wall portion 51, the sliding resistance between the lock knob 12 and the guide wall portion 51 is compared with the guide wall portion 14 of the first embodiment. Small. For this reason, the tilted state of the joystick 3 can be reliably held, and the joystick 3 can be tilted with a light force.
