Description

Hinge

The divisional application that this case is application number is 201080053768.5, denomination of invention is the patent application of hinge

Technical field

The present invention relates to the hinge that the main body that such as can be opened and closed the original copy cover clamp of office equipment to be linked to office equipment is first-class, can be opened and closed the second object of connection thing to be linked to the first object of connection thing.Relating to relative to the first object of connection thing slowly and the technology of reliably closing second object of connection thing specifically.

Background technology

All the time, mostly the office equipment used in the offices such as photocopier, fax, scanning machine is on its main body, be provided with manuscript reading section (contact glass, contact glass), and the original copy cover clamp covering this manuscript reading section is set.

Original copy cover clamp is the original copy cover clamp making the original copy being placed in manuscript reading section be close to manuscript reading section and keep relative to the position of the original copy of manuscript reading section, in general, the end of original copy cover clamp is linked to the end above the main body of office equipment rotationally by hinge.

Such original copy cover clamp needs weight to a certain degree in order to make original copy be close to manuscript reading section.In addition, when master copy automatic conveying device (Auto Document Feeder:ADF) is arranged at original copy cover clamp, the weight of original copy cover clamp to be increased further.

Therefore, the main body of existing link office equipment and the hinge of original copy cover clamp by being supported the weight of original copy cover clamp by spring fitting between the installation component of main body being fixed on office equipment and the supporting member being fixed on original copy cover clamp by the active force of this spring, thus keep the rotational angle (opening and closing angle) relative to the original copy cover clamp of the main body of office equipment with arbitrary angle, to such an extent as to operator can easily carry out making original copy cover clamp rotate (opening and closing) and original copy being placed on the operation of manuscript reading section.Such as, the summary of the invention described in patent documentation 1 as described below.

In addition, even if when mostly above-mentioned hinge is below the threshold value by taking the rotational angle of the original copy cover clamp in the main body relative to office equipment as regulation the decrement rotational angle of spring change the mode that also becomes identical on hinge and the shape of contact site (cam) of spring make an effort, thus make to close original copy cover clamp (original copy cover clamp is contacted with above main body) completely and become possibility.

But, when the weight of original copy cover clamp is larger, have a kind of worry and original copy cover clamp drops when the rotational angle of the original copy cover clamp of the main body relative to office equipment becomes below the value of regulation surgingly and collides with the main body of office equipment.

As the hinge (original copy cover clamp opening and closing device) of the problem solved as previously discussed, it is well known that had an effect by fluid damper (damper) when the rotational angle of the original copy cover clamp of the main body relative to office equipment becomes below the angle of regulation thus make dropping of original copy cover clamp become hinge slowly.Such as, the summary of the invention described in patent documentation 2 as described below.

But it is not the structure being arranged at the fluid damper of the hinge described in patent documentation 2 is comparatively complicated, and number of components is also more, preferred from the viewpoint of manufacturing cost.

As the fluid damper do not used as previously discussed the rotational angle of the original copy cover clamp of the main body relative to office equipment be regulation angle below in make dropping of original copy cover clamp become hinge (original copy cover clamp opening and closing device) slowly, it is well known that the hinge described in following patent documentation 3.

Hinge described in patent documentation 3 possess the main body being fixed on office equipment installation component, be rotationally linked to installation component and be fixed on the supporting member of the original copy cover clamp of office equipment, end winding support in supporting member spring, be fixed on spring another end and be supported in the slide block (slider) contacted on supporting member and with the cam being arranged at installation component slidably; The part relative with supporting member on slide block is alternately formed raised line and groove and the part relative with slide block on supporting member alternately forms raised line and groove, the raised line being formed at slide block is contained in the groove being formed at supporting member, the raised line being formed at supporting member is contained in the groove being formed at slide block, by utilizing the viscous drag of grease by grease-filled and make dropping of original copy cover clamp become slow in the gap of these raised lines and groove.

But, hinge described in patent documentation 3 is because become zero or become very little, so in order to make dropping of original copy cover clamp slowly and effectively use the viscous drag of grease to be difficult relative to the amount of movement (slippage) of the slide block of supporting member in below the angle that the rotational angle of the original copy cover clamp of the main body relative to office equipment is regulation.

Therefore, the second spring 170 exerts a force to the second slide block 160 on the direction of giving prominence to from the second peristome 119a of the second accommodating chamber 119 (being top in present embodiment).

Below, use Fig. 5 and Figure 11 ~ Figure 16, the action of the hinge 100 when closed original copy cover clamp 13 is described.

As shown in figure 13, in the present embodiment, using the rotational angle θ (the rotational angle θ relative to the original copy cover clamp 13 of main body 12) of the original copy cover clamp 13 when namely touching above main body 12 below original copy cover clamp 13 when closing completely at original copy cover clamp 13 as " 0 ° ", and define the rotational angle θ of original copy cover clamp 13 in the mode that the rotational angle θ when original copy cover clamp 13 rotates in the opening direction increases (rotational angle θ become on the occasion of).Further, in the present embodiment, the rotational angle θ of the original copy cover clamp 13 when original copy cover clamp 13 is opened completely is " 50 ° ".

In the present embodiment, when the rotational angle θ of original copy cover clamp 13 is more than 6 ° (θ >=6 °), original copy cover clamp 13 belongs in " electrodeless (Free-stop) region ", belongs to " drop zone " less than original copy cover clamp 13 6 ° (0 °≤θ < 6 °) at the rotational angle θ of original copy cover clamp 13.

" electrodeless region " in present embodiment for (A1) " result from original copy cover clamp 13 weight and using rotational pin 130 as center and act on the rotatory force (moment) of revolving member 120 " with (B1) " result from the first spring 150 active force and using rotational pin 130 as center and act on the rotatory force (moment) of revolving member 120 " region of balancing each other.

As shown in figure 11, when original copy cover clamp 13 belongs to " electrodeless (Free-stop) region ", the first cam part 121b of revolving member 120 is contacted with the contact protrusion 141a of the first slide block 140.

In addition, when original copy cover clamp 13 belongs to " electrodeless (Free-stop) region ", the second cam part 121c of revolving member 120 leaves (not being contacted with the second slide block 160) from the second slide block 160.

The state belonging to " electrodeless (Free-stop) region " at original copy cover clamp 13 with original copy cover clamp 13 closed direction (direction that the rotational angle θ of original copy cover clamp 13 diminishes) is upper rotate, the rotatory force of (A1) increases.

This depends on when the gravity acting on original copy cover clamp 13 being resolved into the composition of the composition of radial direction (being connect the leading section of original copy cover clamp 13 and the direction of rotational pin 130 during side-looking) and circumferencial direction (being the direction perpendicular to radial direction during side-looking), the rotational angle θ of original copy cover clamp 13 becomes less, then the composition of the circumferencial direction i.e. rotatory force of (A1) becomes larger.

On the other hand, the state belonging to " electrodeless (Free-stop) region " at original copy cover clamp 13 with original copy cover clamp 13 is rotated on closed direction, revolving member 120 is that the mode turned clockwise is rotated relative to box component 110 with right side apparent time, and the contact site of the contact protrusion 141a of the first cam part 121b of revolving member 120 and the first slide block 140 changes, the first slide block 140 is depressed and moves downwards (with reference to Figure 12 and Figure 14).

Moved downwards by the first slide block 140, thus the first spring 150 is compressed (total length of the first spring 150 shortens), the active force of the first spring 150 increases, and the rotatory force of (B1) increases.

Its result, when original copy cover clamp 13 belongs to " electrodeless (Free-stop) region " time, even if the rotational angle θ of original copy cover clamp 13 changes, the rotatory force of (A1) and the rotatory force of (B1) still balance each other.More tight, time to belong to " electrodeless (Free-stop) region " when original copy cover clamp 13, even if the rotational angle θ of original copy cover clamp 13 changes, (A1) mode that rotatory force still balances each other with the rotatory force of (B1), presets the shape of the first cam part 121b and contact protrusion 141a.

Therefore, when original copy cover clamp 13 belongs to " electrodeless (Free-stop) region " time, operator lets go from original copy cover clamp 13, the rotational angle θ of original copy cover clamp 13 is kept.

" drop zone " in present embodiment is the region that the rotatory force of (A1) becomes the rotatory force being greater than (B1).In the present embodiment, drop zone is set to from the closed state (θ=0 °) of original copy cover clamp 13 to only carrying out the scope the state opened with the angle of regulation (for θ=6 ° present embodiment).

When original copy cover clamp 13 belongs to " drop zone " time, operator lets go from original copy cover clamp 13, original copy cover clamp 13 rotates on closed direction due to deadweight (being the difference of the rotatory force of (A1) and the rotatory force of (B1) closely).

As shown in figure 12, when original copy cover clamp 13 belongs to " drop zone " time, the first cam part 121b of revolving member 120 is contacted with the contact protrusion 141a of the first slide block 140.

But, as shown in figure 14, when original copy cover clamp 13 belongs to " drop zone " time, even if the rotational angle θ of original copy cover clamp 13 changes, also can not change relative to the position of the first slide block 140 of box component 110.More closely, with when original copy cover clamp 13 belongs to " drop zone " time, even if the rotational angle θ of original copy cover clamp 13 changes, relative to the mode that the position of the first slide block 140 of box component 110 does not also change, preset the shape of the first cam part 121b and contact protrusion 141a.

Its result, when original copy cover clamp 13 belongs to " drop zone " time, the rotatory force of (B1) becomes zero in fact, and the rotatory force of (A1) is greater than the rotatory force of (B1).

As shown in figure 12, when original copy cover clamp 13 belongs to " drop zone " time, the second cam part 121c of revolving member 120 is contacted with the contact-making surface 160a of the second slide block 160.

Therefore, the state belonging to " drop zone " at original copy cover clamp 13 with original copy cover clamp 13 is rotated on closed direction, revolving member 120 is that the mode turned clockwise is rotated relative to box component 110 with right side apparent time, and the contact site of the contact-making surface 160a of the second cam part 121c of revolving member 120 and the second slide block 160 changes, the second slide block 160 is depressed and moves downwards (with reference to Fig. 5, Figure 12 and Figure 15).

When the second slide block 160 moves downwards, result from the applied outer peripheral face in the second slide block 160 and the second accommodating chamber 119 inner peripheral surface contact portion on the drag effect of viscous drag of grease in the second slide block 160.

Therefore, when original copy cover clamp 13 belongs to " drop zone " time, (A1) part of rotatory force by result from grease viscous drag resistance and be cancelled, and original copy cover clamp 13 carries out slow (by relaxing) of rotating on closed direction.

Its result, because original copy cover clamp 13 to be gently contacted with above main body 12 (can not with strong impact), so can slowly and reliably closing original copy cover clamp 13.

Also have, when operator's original copy cover clamp 13 dominated by hand also makes original copy cover clamp 13 rotate in the opening direction, second slide block 160 is because being moved upward lipophobic viscous drag by the active force of the second spring 170, so when original copy cover clamp 13 belongs to " drop zone " time, can keep " the second cam part 121c of revolving member 120 is contacted with the state of the contact-making surface 160a of the second slide block 160 ".

On the other hand, the state belonging to " electrodeless (Free-stop) region " at original copy cover clamp 23 with original copy cover clamp 23 is rotated on closed direction, box component 210 is that the mode turned clockwise is rotated relative to revolving member 220 with right side apparent time, the contact site of the contact-making surface 241a of the first cam part 221a of revolving member 220 and the contact site 241 of the first slide block 240 changes, and the first slide block 240 to move submerging to the direction of the inside of the first accommodating chamber 211.

To be moved to the direction of the inside of the first accommodating chamber 211 submerging by the first slide block 240, thus the first spring 250 is compressed (total length of the first spring 250 shortens) and the increase of the active force of the first spring 250, thus the rotatory force of (B2) increases.

Its result, when original copy cover clamp 23 belongs to " electrodeless (Free-stop) region " time, even if the rotational angle θ of original copy cover clamp 23 changes, the rotatory force of (A2) and the rotatory force of (B2) still balance each other.More tight is, to belong to " electrodeless (Free-stop) region " when original copy cover clamp 23 though time original copy cover clamp 23 rotational angle θ change, the mode that the rotatory force of (A2) and the rotatory force of (B2) still balance each other presets the shape of the first cam part 221a and contact site 241.

Therefore, when original copy cover clamp 23 belongs to " electrodeless (Free-stop) region " time, when operator lets go from original copy cover clamp 23, the rotational angle θ of original copy cover clamp 23 is kept.

" drop zone " in present embodiment is the region that the rotatory force of (A2) is greater than the rotatory force of (B2).

When original copy cover clamp 23 belongs to " drop zone " time, when operator lets go from original copy cover clamp 23, original copy cover clamp 23 rotates on closed direction due to deadweight (closely, being the difference of the rotatory force of (A2) and the rotatory force of (B2)).

When original copy cover clamp 23 belongs to " drop zone " time, the first cam part 221a of revolving member 220 is contacted with the contact-making surface 241a of the contact site 241 of the first slide block 240.

But, when original copy cover clamp 23 belongs to " drop zone " time, even if the rotational angle θ of original copy cover clamp 23 changes, also can not change relative to the position of the first slide block 240 of box component 210.More closely, to belong to " drop zone " when original copy cover clamp 23 though time original copy cover clamp 23 rotational angle θ change, the mode also do not changed relative to the position of the first slide block 240 of box component 210 presets the shape of the first cam part 221a and contact site 241.

Its result, when original copy cover clamp 23 belongs to " drop zone " time, the rotatory force of (B2) becomes zero in fact, and the rotatory force of (A2) is greater than the rotatory force of (B2).

When original copy cover clamp 23 belongs to " drop zone " time, the second cam part 221b of revolving member 220 is contacted with the contact-making surface 261 of the second slide block 260.

Therefore, the state belonging to " drop zone " at original copy cover clamp 23 with original copy cover clamp 23 is rotated on closed direction, box component 210 is that the mode turned clockwise is rotated relative to revolving member 220 with right side apparent time, and the contact site of the contact-making surface 261 of the second cam part 221b of revolving member 220 and the second slide block 260 changes, the second slide block 260 moves up in the side to the inside of the second accommodating chamber 212 of submerging.

At the second slide block 260 when submerging and moving to the direction of the inside of the second accommodating chamber 212, result from the applied outer peripheral face in the second slide block 260 and the second accommodating chamber 212 inner peripheral surface contact portion on the drag effect of viscous drag of grease in the second slide block 260.

Therefore, when original copy cover clamp 23 belongs to " drop zone " time, (A2) part of rotatory force by result from grease viscous drag resistance and be cancelled, and original copy cover clamp 23 carries out slow (by relaxing) of rotating on closed direction.

Its result, because original copy cover clamp 23 is gently contacted with above main body 22, so can slowly and reliably closing original copy cover clamp 23.

Also have, when operator's original copy cover clamp 23 dominated by hand also makes original copy cover clamp 23 rotate in the opening direction, second slide block 260 moves up in the side outstanding from the second peristome 212a to lipophobic viscous drag because of the active force by the second spring 270, so when original copy cover clamp 23 belongs to " drop zone " time, can keep " the second cam part 221b of revolving member 220 is contacted with the state of the contact-making surface 261 of the second slide block 260 ".

As previously discussed, hinge 200 is a kind of hinges that can be opened and closed original copy cover clamp 23 to be linked to main body 22, possess: box component 210, be formed with first accommodating chamber 211 with the first peristome 211a and second accommodating chamber 212 with the second peristome 212a, and be fixed in the original copy cover clamp 23 of compounding machine 21; Revolving member 220, is fixed in the main body 22 of compounding machine 21, and is linked to box component 210 rotationally; First slide block 240, is housed inside the first accommodating chamber 211, and contacts with the inner peripheral surface of the first accommodating chamber 211 and can move in the direction of giving prominence to from the first peristome 211a and submerging to the direction of the inside of the first accommodating chamber 211; First spring 250, is housed inside the first accommodating chamber 211, and exerts a force to the first slide block 240 on the direction outstanding from the first peristome 211a; Second slide block 260, is housed inside the second accommodating chamber 212, and contacts with the inner peripheral surface of the second accommodating chamber 212 and can move in the direction of giving prominence to from the second peristome 212a and submerging to the direction of the inside of the second accommodating chamber 212; Second spring 270, is housed inside the second accommodating chamber 212, and exerts a force to the second slide block 260 on the direction outstanding from the second peristome 212a; Revolving member 220 be formed the first cam part 221a of being contacted with the first slide block 240 (the contact-making surface 241a of contact site 241) and be formed with the second cam part 221b being contacted with the second slide block 260 (contact-making surface 261), in the gap between the second slide block 260 and the inner peripheral surface of the second accommodating chamber 212, being configured with grease.

Below, use Figure 30, Figure 35 and Figure 36, the action of the hinge 300 when closed original copy cover clamp 33 is described.

In the present embodiment, using the rotational angle θ (the rotational angle θ relative to the original copy cover clamp 33 of main body 32) of the original copy cover clamp 33 when namely touching above main body 32 below original copy cover clamp 33 when closing completely at original copy cover clamp 33 as " 0 ° ", and define the rotational angle θ (with reference to Figure 30) of original copy cover clamp 33 in the mode that the rotational angle θ when original copy cover clamp 33 rotates in the opening direction increases (rotational angle θ become on the occasion of).

In the present embodiment, when the rotational angle θ of original copy cover clamp 33 is more than 18 ° (θ >=18 °), original copy cover clamp 33 belongs in " electrodeless (Free-stop) region ", belongs to " drop zone " less than original copy cover clamp 33 18 ° (0 °≤θ < 18 °) at the rotational angle θ of original copy cover clamp 33.

" electrodeless (Free-stop) region " in present embodiment for (A3) " result from original copy cover clamp 33 weight and using rotational pin 330 as center and act on the rotatory force (moment) of revolving member 320 " with (B3) " result from the first spring 350 active force and using rotational pin 330 as center and act on the rotatory force (moment) of revolving member 320 " region of balancing each other.

When original copy cover clamp 33 belongs to " electrodeless (Free-stop) region ", the first cam part 321b321a of revolving member 320 is contacted with the contact protrusion 341a341a of the mainboard 341 of the first slide block 340.

In addition, when original copy cover clamp 33 belongs to " electrodeless (Free-stop) region ", the second cam part 321c of revolving member 320 leaves (not being contacted with the second slide block 360) from the second slide block 360.

The state belonging to " electrodeless (Free-stop) region " at original copy cover clamp 33 with original copy cover clamp 33 is rotated on closed direction, the rotatory force of (A3) increases.

On the other hand, the state belonging to " electrodeless (Free-stop) region " at original copy cover clamp 33 with original copy cover clamp 33 is rotated on closed direction, revolving member 320 is that the mode turned clockwise is rotated relative to box component 310 with right side apparent time, the contact site of the contact protrusion 341a341a of the first cam part 321b321b of revolving member 320 and the mainboard 341 of the first slide block 340 changes, and the first slide block 340 moves up in the side to the inside of main accommodating chamber 316 of submerging.

To be moved to the direction of the inside of main accommodating chamber 316 submerging by the first slide block 340, thus the first spring 350 is compressed (total length of the first spring 350 diminishes), thus the active force of the first spring 350 increases, and the rotatory force of (B3) increases.

Its result, when original copy cover clamp 33 belongs to " electrodeless (Free-stop) region " time, even if the rotational angle θ of original copy cover clamp 33 changes, the rotatory force of (A3) and the rotatory force of (B3) still balance each other.More tight is, to belong to " electrodeless (Free-stop) region " when original copy cover clamp 33 though time original copy cover clamp 33 rotational angle θ change, the mode that the rotatory force of (A3) and the rotatory force of (B3) still balance each other presets the shape of the first cam part 321b321b and contact protrusion 341a341a.

Therefore, when original copy cover clamp 33 belongs to " electrodeless (Free-stop) region " time, when operator lets go from original copy cover clamp 33, the rotational angle θ of original copy cover clamp 33 is kept.

" drop zone " in present embodiment is the region that the rotatory force of (A3) is greater than the rotatory force of (B3).

When original copy cover clamp 33 belongs to " drop zone " time, when operator lets go from original copy cover clamp 33, original copy cover clamp 33 rotates on closed direction due to deadweight (being the difference of the rotatory force of (A3) and the rotatory force of (B3) closely).

When original copy cover clamp 33 belongs to " drop zone " time, the first cam part 321b321b of revolving member 320 is contacted with the contact protrusion 341a341a of the mainboard 341 of the first slide block 340.

But, when original copy cover clamp 33 belongs to " drop zone " time, even if the rotational angle θ of original copy cover clamp 33 changes, also can not change relative to the position of the first slide block 340 of box component 310.More closely, to belong to " drop zone " when original copy cover clamp 33 though time original copy cover clamp 33 rotational angle θ change, the mode also do not changed relative to the position of the first slide block 340 of box component 310 presets the shape of the first cam part 321b321b and contact protrusion 341a341a.

Its result, when original copy cover clamp 33 belongs to " drop zone " time, the rotatory force of (B3) becomes zero in fact, and the rotatory force of (A3) is greater than the rotatory force of (B3).

When original copy cover clamp 33 belongs to " drop zone " time, the second cam part 321c of revolving member 320 is contacted with the contact-making surface 361 of the second slide block 360.

Therefore, the state belonging to " drop zone " at original copy cover clamp 33 with original copy cover clamp 33 is rotated on closed direction, revolving member 320 is that the mode turned clockwise is rotated relative to box component 310 with right side apparent time, and the contact site of the contact-making surface 361 of the second cam part 321c of revolving member 320 and the second slide block 360 changes, the second slide block 360 to move submerging to the direction (in present embodiment for below) of the inside of secondary accommodating chamber 347.

At the second slide block 360 when submerging and moving to the direction of the inside of secondary accommodating chamber 347, result from the applied outer peripheral face in the second slide block 360 and secondary accommodating chamber 347 inner peripheral surface contact portion on the drag effect of viscous drag of grease in the second slide block 360.

Therefore, when original copy cover clamp 33 belongs to " drop zone " time, (A3) part of rotatory force by result from grease viscous drag resistance and be cancelled, and original copy cover clamp 33 carries out slow (by relaxing) of rotating on closed direction.

Its result, because original copy cover clamp 33 is gently contacted with above main body 32, so can slowly and reliably closing original copy cover clamp 33.

Also have, when operator's original copy cover clamp 33 dominated by hand also makes original copy cover clamp 33 rotate in the opening direction, second slide block 360 is because being come by the active force of the second spring 370 to move in the direction (in present embodiment be top) outstanding from secondary peristome 347a lipophobic viscous drag, so when original copy cover clamp 33 belongs to " drop zone " time, can keep " the second cam part 321c of revolving member 320 is contacted with the state of the contact-making surface 361 of the second slide block 360 ".

The contact portion of the outer peripheral face of the second slide block 460 and the inner peripheral surface of the second accommodating chamber 421 is coated with grease.In other words, the gap (comprising the gap between direction protrusion 462462 and guide groove 421b421b) between the second slide block 460 and the inner peripheral surface of the second accommodating chamber 421 configures grease.

The grease being configured in the gap between the second slide block 460 and the inner peripheral surface of the second accommodating chamber 421 is the one of the execution mode of viscoid involved in the present invention.

Second spring 470 is the one of the execution mode of the second force application component involved in the present invention.

Second spring 470 of present embodiment is metal wind spring, and is Compress Spring (to be carried out the spring used by the state compressed).

As shown in figure 48, the second spring 470 is housed inside in the second accommodating chamber 421 of the second slider component 420.

Be housed inside an ends contact of the second spring 470 in the second accommodating chamber 421 in the bottom surface of the second accommodating chamber 421, the spring that another end of the second spring 470 is housed inside the second slide block 460 bears hole 463 and is contacted with and is formed on the step surface that spring bears the inside in hole 463.

Therefore, the second spring 470 exerts a force to the second slide block 460 on the direction of giving prominence to from the second peristome 421a of the second accommodating chamber 421.

Below, use Figure 42, Figure 47 and Figure 48, the action of the hinge 400 when closed original copy cover clamp 43 is described.

In the present embodiment, using the rotational angle θ (the rotational angle θ relative to the original copy cover clamp 43 of main body 42) of the original copy cover clamp 43 when namely touching above main body 42 below original copy cover clamp 43 when closing completely at original copy cover clamp 43 as " 0 ° ", and define the rotational angle θ (with reference to Figure 42) of original copy cover clamp 43 in the mode that the rotational angle θ when original copy cover clamp 43 rotates in the opening direction increases (rotational angle θ become on the occasion of).

In the present embodiment, when the rotational angle θ of original copy cover clamp 43 is more than 18 ° (θ >=18 °), original copy cover clamp 43 belongs in " electrodeless (Free-stop) region ", belongs to " drop zone " less than original copy cover clamp 43 18 ° (0 °≤θ < 18 °) at the rotational angle θ of original copy cover clamp 43.

" electrodeless (Free-stop) region " in present embodiment for (A4) " result from original copy cover clamp 43 weight and using rotational pin 430 as center and act on the rotatory force (moment) of the second box component 420 " with (B4) " result from the first spring 450 active force and using rotational pin 430 as center and act on the rotatory force (moment) of the second box component 420 " region of balancing each other.

When original copy cover clamp 43 belongs to " electrodeless (Free-stop) region ", the first cam part 422 of the second box component 420 is contacted with the contact-making surface 441a of the contact site 441 of the first slide block 440 (with reference to Figure 47).

In addition, when original copy cover clamp 43 belongs to " electrodeless (Free-stop) region ", the second cam part 412 of the first box component 410 is left from the second slide block 460, is not contacted with the second slide block 460 (with reference to Figure 48).

The state belonging to " electrodeless (Free-stop) region " at original copy cover clamp 43 with original copy cover clamp 43 is rotated on closed direction, the rotatory force of (A4) increases.

On the other hand, the state belonging to " electrodeless (Free-stop) region " at original copy cover clamp 43 with original copy cover clamp 33 is rotated on closed direction, second box component 420 is that the mode turned clockwise is rotated relative to the first box component 410 with right side apparent time, the contact site of the contact-making surface 441a of the first cam part 422 of the second box component 420 and the contact site 441 of the first slide block 440 changes, and the first slide block 440 is upper mobile in the direction (below) to the inside of the first accommodating chamber 411 of submerging.

To be moved to the direction of the inside of the first accommodating chamber 411 submerging by the first slide block 440, thus the first spring 450 is compressed (total length of the first spring 450 diminishes), thus the active force of the first spring 450 increases, and the rotatory force of (B4) increases.

Its result, when original copy cover clamp 43 belongs to " electrodeless (Free-stop) region " time, even if the rotational angle θ of original copy cover clamp 43 changes, the rotatory force of (A4) and the rotatory force of (B4) still balance each other.More tight is, to belong to " electrodeless (Free-stop) region " when original copy cover clamp 43 though time original copy cover clamp 43 rotational angle θ change, the mode that the rotatory force of (A4) and the rotatory force of (B4) still balance each other presets the shape of the first cam part 422 and contact site 441.

Therefore, when original copy cover clamp 43 belongs to " electrodeless (Free-stop) region " time, when operator lets go from original copy cover clamp 43, the rotational angle θ of original copy cover clamp 43 is kept.

" drop zone " in present embodiment is the region that the rotatory force of (A4) is greater than the rotatory force of (B4).

When original copy cover clamp 43 belongs to " drop zone " time, when operator lets go from original copy cover clamp 43, original copy cover clamp 43 rotates on closed direction due to deadweight (being the difference of the rotatory force of (A4) and the rotatory force of (B4) closely).

When original copy cover clamp 43 belongs to " drop zone " time, the first cam part 422 of the second box component 420 is contacted with the contact-making surface 441a of the contact site 441 of the first slide block 440.

But, when original copy cover clamp 43 belongs to " drop zone " time, even if the rotational angle θ of original copy cover clamp 43 changes, also can not change relative to the position of the first slide block 440 of the first box component 410.More closely, to belong to " drop zone " when original copy cover clamp 43 though time original copy cover clamp 43 rotational angle θ change, the mode also do not changed relative to the position of the first slide block 440 of the first box component 410 presets the shape of the first cam part 422 and contact site 441.

Its result, when original copy cover clamp 43 belongs to " drop zone " time, the rotatory force of (B4) becomes zero in fact, and the rotatory force of (A4) is greater than the rotatory force of (B4).

When original copy cover clamp 43 belongs to " drop zone " time, the second cam part 412 of the first box component 410 is contacted with the contact-making surface 461 of the second slide block 460.

Therefore, the state belonging to " drop zone " at original copy cover clamp 43 with original copy cover clamp 43 is rotated on closed direction, second box component 420 is that the mode turned clockwise is rotated relative to the first box component 410 with right side apparent time, and the contact site of the contact-making surface 461 of the second cam part 412 of the first box component 410 and the second slide block 460 changes, the second slide block 460 to move submerging to the direction of the inside of the second accommodating chamber 421.

At the second slide block 460 when submerging and moving to the direction of the inside of the second accommodating chamber 421, result from the drag effect of the applied outer peripheral face in the second slide block 460 (four sides) and the viscous drag of the grease in the contact portion of the inner peripheral surface of the second accommodating chamber 421 in the second slide block 460.

Therefore, when original copy cover clamp 43 belongs to " drop zone " time, (A4) part of rotatory force by result from grease viscous drag resistance and be cancelled, and original copy cover clamp 43 carries out slow (by relaxing) of rotating on closed direction.

Its result, because original copy cover clamp 43 is gently contacted with above main body 42, so can slowly and reliably closing original copy cover clamp 43.

Also have, when operator's original copy cover clamp 43 dominated by hand also makes original copy cover clamp 43 rotate in the opening direction, second slide block 460 moves up in the side outstanding from the second peristome 421a to lipophobic viscous drag because of the active force by the second spring 470, so when original copy cover clamp 43 belongs to " drop zone " time, can keep " the second cam part 412 of the first box component 410 is contacted with the state of the contact-making surface 461 of the second slide block 460 ".

Therefore, the second spring 599 exerts a force to the second slide block 590 on the direction of giving prominence to from the second peristome 561a of the second accommodating chamber 561.

Below, use Figure 52, Figure 58 and Figure 65, the action of the hinge 500 when closed original copy cover clamp 53 is described.

In the present embodiment, using the rotational angle θ (the rotational angle θ relative to the original copy cover clamp 53 of main body 52) of the original copy cover clamp 53 when namely touching above main body 52 below original copy cover clamp 53 when closing completely at original copy cover clamp 53 as " 0 ° ", and define the rotational angle θ (with reference to Figure 52) of original copy cover clamp 53 in the mode that the rotational angle θ when original copy cover clamp 53 rotates in the opening direction increases (rotational angle θ become on the occasion of).

In the present embodiment, when the rotational angle θ of original copy cover clamp 53 is more than 18 ° (θ >=18 °), original copy cover clamp 53 belongs in " electrodeless (Free-stop) region ", belongs to " drop zone " less than original copy cover clamp 53 18 ° (0 °≤θ < 18 °) at the rotational angle θ of original copy cover clamp 53.

" electrodeless (Free-stop) region " in present embodiment for (A5) " result from original copy cover clamp 53 weight and using rotational pin 530 as center and act on the rotatory force (moment) of main box component 510 " with (B5) " result from the first spring 549 active force and using rotational pin 530 as center and act on the rotatory force (moment) of main box component 510 " region of balancing each other.

When original copy cover clamp 53 belongs to " electrodeless (Free-stop) region ", the first cam part 521a of main revolving member 520 is contacted with the contact-making surface 541a of the contact site 541 of the first slide block 540 (with reference to Figure 58).

In addition, when original copy cover clamp 53 belongs to " electrodeless (Free-stop) region ", the second cam part 571a of secondary revolving member 570 leaves from the second slide block 590, is not contacted with the second slide block 590 (with reference to Figure 65).

The state belonging to " electrodeless (Free-stop) region " at original copy cover clamp 53 with original copy cover clamp 53 is rotated on closed direction, the rotatory force of (A5) increases.

On the other hand, the state belonging to " electrodeless (Free-stop) region " at original copy cover clamp 53 with original copy cover clamp 53 is rotated on closed direction, main box component 510 is that the mode turned clockwise is rotated relative to main revolving member 520 (auxiliary box body component 560 is relative to secondary revolving member 570) with right side apparent time, the contact site of the contact-making surface 541a of the first cam part 521a of main revolving member 520 and the contact site 541 of the first slide block 540 changes, thus the first slide block 540 moves up in the side to the inside of the first accommodating chamber 511 of submerging.

To be moved to the direction of the inside of the first accommodating chamber 511 submerging by the first slide block 540, thus the first spring 549 is compressed (total length of the first spring 549 shortens), and the active force of the first spring 549 increases, thus the rotatory force of (B5) increases.

Its result, when original copy cover clamp 53 belongs to " electrodeless (Free-stop) region " time, even if the rotational angle θ of original copy cover clamp 53 changes, the rotatory force of (A5) and the rotatory force of (B5) still balance each other.More tight is, to belong to " electrodeless (Free-stop) region " when original copy cover clamp 53 though time original copy cover clamp 53 rotational angle θ change, the mode that the rotatory force of (A5) and the rotatory force of (B5) still balance each other presets the shape of the first cam part 521a and contact site 541.

Therefore, when original copy cover clamp 53 belongs to " electrodeless (Free-stop) region " time, when operator lets go from original copy cover clamp 53, the rotational angle θ of original copy cover clamp 53 is kept.

" drop zone " in present embodiment is the region that the rotatory force of (A5) is greater than the rotatory force of (B5).

When original copy cover clamp 53 belongs to " drop zone " time, when operator lets go from original copy cover clamp 53, original copy cover clamp 53 rotates on closed direction due to deadweight (closely, being the difference of the rotatory force of (A5) and the rotatory force of (B5)).

When original copy cover clamp 53 belongs to " drop zone " time, the first cam part 521a of main revolving member 520 is contacted with the contact-making surface 541a of the contact site 541 of the first slide block 540.

But, when original copy cover clamp 53 belongs to " drop zone " time, even if the rotational angle θ of original copy cover clamp 53 changes, also can not change relative to the position of the first slide block 540 of main box component 510.More closely, to belong to " drop zone " when original copy cover clamp 53 though time original copy cover clamp 53 rotational angle θ change, the mode also do not changed relative to the position of the first slide block 540 of main box component 510 presets the shape of the first cam part 521a and contact site 541.

Its result, when original copy cover clamp 53 belongs to " drop zone " time, the rotatory force of (B5) becomes zero in fact, and the rotatory force of (A5) is greater than the rotatory force of (B5).

When original copy cover clamp 53 belongs to " drop zone " time, the second cam part 571a of secondary revolving member 570 is contacted with the contact-making surface 591 of the second slide block 590.

Therefore, the state belonging to " drop zone " at original copy cover clamp 53 with original copy cover clamp 53 is rotated on closed direction, auxiliary box body component 560 is that the mode turned clockwise is rotated relative to secondary revolving member 570 with right side apparent time, and the contact site of the contact-making surface 591 of the second cam part 571a of secondary revolving member 570 and the second slide block 590 changes, thus the second slide block 590 moves up in the side to the inside of the second accommodating chamber 561 of submerging.

At the second slide block 590 when submerging and moving to the direction of the inside of the second accommodating chamber 561, result from the drag effect of the applied outer peripheral face in the second slide block 590 (four sides) and the viscous drag of the grease of the contact portion of the inner peripheral surface of the second accommodating chamber 561 in the second slide block 590.

Therefore, when original copy cover clamp 53 belongs to " drop zone " time, (A5) part of rotatory force by result from grease viscous drag resistance and be cancelled, thus original copy cover clamp 53 carries out slow (by relaxing) of rotating on closed direction.

Its result, because original copy cover clamp 53 is gently contacted with above main body 52, so can slowly and reliably closing original copy cover clamp 53.

Also have, when operator's original copy cover clamp 53 dominated by hand also makes original copy cover clamp 53 rotate in the opening direction, second slide block 590 moves up, so can keep when original copy cover clamp 53 belongs to " drop zone " time " the second cam part 571a of secondary revolving member 570 is contacted with the state of the contact-making surface 591 of the second slide block 590 " in the side outstanding from the second peristome 561a to lipophobic viscous drag because of the active force by the second spring 599.
