Then, the structure about the stop member 47 of web media holding device 51 is described in detail.
Shown in Fig. 4 be observe the web media holding device 51 of the present embodiment from oblique upper stop member 47 grade seen by sectional block diagram.In addition, shown in Fig. 5 is observe sectional block diagram seen by stop member 47 grade below tiltedly.Further in addition, shown in Fig. 6 is the sectional view representing stop member 47 grade.
As shown in Fig. 4 ~ Fig. 6, the base portion 4 being arranged at the below of the first maintaining part 3 of web media holding device 51 is set to slide relative to the first duct member 7a, the second duct member 7b.Such as, the first duct member 7a of in stop member 47, two first duct member 7a, the second duct member 7b of annular is installed by the ring of stop member 47 in base portion 4.Here, stop member 47 is formed as, and can carry out face contact with the periphery of the first duct member 7a.
And, be configured to, rotated by the grip 36 of the bolt 50 (with reference to Fig. 6) making above-mentioned band handgrip, make stop member 47 to the size variation of the thrust pressure F (with reference to Fig. 6) of the first contacted duct member 7a effect thus.When the size of thrust pressure F is larger than pre-sizing, friction force increases, and the first maintaining part 3 becomes the state fixing relative to the first duct member 7a (and second duct member 7b) thus.On the other hand, when the size of thrust pressure F is less than described pre-sizing, friction force reduces, and the first maintaining part 3 becomes the state can slided relative to the first duct member 7a, the second duct member 7b thus.
Below, be described about detailed structure.
The first hole portion of hole portion the 44 ~ three 46 (with reference to Fig. 5) is formed in base portion 4.And, make a part for the stop member 47 of annular be embedded in the first hole portion 46 of hole portion the 44 ~ three respectively, make stop member 47 be installed on base portion 4 thus.On the other hand, the first abutting part 48 and the second abutting part 49 is formed with at stop member 47.
Wherein, the first abutting part 48 is embedded in the first hole portion 44, and abuts with around the first hole portion 44 or its (with reference to Fig. 6).In addition, the second abutting part 49, the circumference of the first duct member 7a in the ring of stop member 47 is formed at the position different from the first abutting part 48.And the second abutting part 49 is set to, abut with the smooth top of the bolt 50 of above-mentioned band handgrip.Be provided with the bolt 50 of above-mentioned band handgrip in base portion 4, female threaded portion 10 has been imbedded in the installation position in base portion 4.Therefore, by operating the bolt 50 with rotating band handgrip to grip 36, make thus to be with the top of the bolt 50 of handgrip to move.And, the position of the second abutting part 49 can be made to move.
In addition, base portion 4 is provided with the first positioning element the 41 ~ three positioning element 43.Wherein, the periphery of the first duct member 7a that the first positioning element 41 contacts with stop member 47 with the second positioning element 42 contacts.And the first positioning element 41 is configured to, as in the Z-direction of above-below direction, the position of the first maintaining part 3 relative to the first duct member 7a can be determined accurately.
In addition, the second positioning element 42 is configured to, and can determine the position of the first maintaining part 3 relative to the first duct member 7a in the Y-axis direction accurately.On the other hand, the 3rd positioning element 43 is configured to, and the periphery of the second duct member 7b contacted with discord stop member 47 contacts.And the 3rd positioning element 43 is configured to, the posture of the first maintaining part 3 relative to the first duct member 7a centered by X-axis, the second duct member 7b can be determined accurately.
By making grip 36 rotate to the direction tighted a bolt, make to be with the bolt 50 of handgrip to rotate.Thus, the top of the bolt 50 of band handgrip is moved to the direction of the second abutting part 49 close to stop member 47, pushes the second abutting part 49 and second abutting part 49 is moved to the direction of arrow of Y-axis.Here, the first abutting part 48 contacts near the first hole portion 44 of an A (with reference to Fig. 6) and base portion 4 or its.Therefore, the rotation counterclockwise centered by the first duct member 7a of stop member 47 in Fig. 6 is limited.
In addition, at the some B of the second abutting part 49, make by making grip 36 rotate to the direction tighted a bolt to be with the top of bolt 50 of handgrip to push the direction of the second abutting part 49, as long as have to the anti-clockwise torque component centered by the first duct member 7a of the periphery along the first duct member 7a in Fig. 6.Because the thrust pressure F in the interval between described later some A, some B can be made thus to increase.
Therefore, the interval between the some A in circumference in stop member 47, the first duct member 7a and the some B of the second abutting part 49, effect is strong, makes between invocation point A-B by towing laterally.Its result, stop member 47 can contact with the outer peripheral face of the first duct member 7a in the interval between an A-B, with to the first duct member 7a effect thrust pressure F.And, make the friction force produced between the inner side of the ring of stop member 47 and the outer peripheral face of the first duct member 7a be more than pre-sizing by thrust pressure F, the first maintaining part 3 becomes the state secured relative to the first duct member 7a (and second duct member 7b) thus.
Its result, in this condition, the periphery plane-plane contact of stop member 47 and the first duct member 7a, so can not damage the outer peripheral face of the first duct member 7a.In addition, both can not be crushed also can not perforate for the first duct member 7a of hollow.
In addition, stop member 47, preferably, is formed by having flexible material.The thrust pressure F approximate equality at described the position contacted can be made.Because: the possibility more reliably can eliminating damage first duct member 7a thus.
In addition, now, the direction be oriented compared with the direction of arrow of Y-axis slightly upward of thrust pressure F.Its reason is: the top of bolt 50 of band handgrip is moved, and the second abutting part 49 is subject to the power of the direction of arrow of Y-axis and the direction of arrow to Y-axis moves thus.Because: now, some A fixes, in contrast, some B moves, so the mode effect of being mentioned by the first duct member 7a with the shape of the inner side by ring is strong.
And by thrust pressure F, the first duct member 7a is pressed in the first positioning element 41 and the second positioning element 42.That is, thrust pressure F towards being configured to, in the circumference of the first duct member 7a, namely the contact site, face that C and the second positioning element 42 and the first duct member 7a are put in the contact site, face towards the first positioning element 41 and the first duct member 7a is namely put between D, pushes the first duct member 7a.Now, some A and some B, the some C relation with some D, the position only will putting the position in the interval of A-B and the interval of some C-D has with the center of the first duct member 7a point-symmetric relation that is benchmark or is similar to point-symmetric relation.
Here, the 3rd positioning element 43 contacts with the periphery of the second duct member 7b all the time because of the deadweight of the first maintaining part 3.Therefore, under the state that the first maintaining part 3 has been fixed, can determine that the first maintaining part 3 is relative to the position of the first duct member 7a, the second duct member 7b and posture accurately.
On the other hand, by making grip 36 rotate to the direction of unclamping bolt, make thus to be with the bolt 50 of handgrip to rotate.Thus, the direction that the top of the bolt 50 of band handgrip is left to stop member 47 from the first abutting part 49 is moved, and the second abutting part 49 is moved to the direction of arrow opposite sense with Y-axis.Therefore, stop member 47 reduces the thrust pressure F of the first duct member 7a effect.Its result, the friction force produced between the inner side of the ring of stop member 47 and the outer peripheral face of the first duct member 7a becomes and is less than pre-sizing, and the first maintaining part 3 becomes the state can slided relative to the first duct member 7a, the second duct member 7b thus.
