Therefore, the hinge of the existing main body for linking office equipment and original copy cover clamp is fixed on by the way that spring is installed on The installation component of the main body of office equipment and it is fixed between the supporting member of original copy cover clamp and by the active force branch of the spring The weight of original copy cover clamp is supportted, so as to keep the rotation of the original copy cover clamp of the main body relative to office equipment with arbitrary angle Angle (opening and closing angle), rotates (opening and closing) and is placed on original copy so that operator easily can enter to exercise original copy cover clamp The operation of manuscript reading section.For example, the content of the invention described in patent document 1 as described below.

In addition, above-mentioned hinge mostly be by using the rotational angle of the original copy cover clamp in the main body relative to office equipment as When below defined threshold value the decrement of spring changed even if rotational angle also turn into identical mode on hinge with The shape of the contact site (cam) of spring is made an effort, so that closure original copy cover clamp completely (makes original copy cover clamp be contacted with master Above body) it is possibly realized.

But, in the case where the weight of original copy cover clamp is larger, have a kind of worry i.e. original copy cover clamp relative to The rotational angle of the original copy cover clamp of the main body of office equipment dropped surgingly when turning into defined value below and with office The main body of equipment collides.

It is used as the hinge (original copy gland plate open-close device) solved the problem of as previously discussed, it is well known that relative Pass through fluid damping in the case that the rotational angle of the original copy cover clamp of the main body of office equipment turns into below defined angle Device (damper) is had an effect so that dropping for original copy cover clamp becomes slow hinge.For example, patent as described below The content of the invention described in document 2.

But, the construction of the fluid damper for the hinge being arranged at described in patent document 2 is complex, number of components It is more, it is not preferred from the viewpoint of manufacturing cost.

As without using fluid damper as described above in the original copy cover clamp of the main body relative to office equipment Rotational angle dropping for original copy cover clamp is become slow hinge (original copy cover clamp is opened Close device), it is well known that the hinge described in following patent document 3.

Hinge described in patent document 3 possesses the installation component for the main body for being fixed on office equipment, rotationally linked In installation component and it is fixed on the bullet that the supporting member of original copy cover clamp of office equipment, an end are fixed on supporting member Spring, another end for being fixed on spring and it is slidably supported on supporting member and with being arranged at the convex of installation component Take turns the sliding block (slider) being in contact；Raised line and groove are alternately formed on the part relative with supporting member on sliding block And raised line and groove are alternately formed on the part relative with sliding block on supporting member, the raised line that will be formed in sliding block holds The groove for being formed at supporting member is contained in, the raised line that will be formed in supporting member is contained in the groove for being formed at sliding block, by inciting somebody to action It is grease-filled in the gap of these raised lines and groove so as to making the change of dropping of original copy cover clamp using the viscous drag of grease Obtain slowly.

But, the hinge described in patent document 3 is because turn of the original copy cover clamp in the main body relative to office equipment Amount of movement (slippage) when dynamic angle is below defined angle relative to the sliding block of supporting member turn into zero or into To be very small, so in order that the viscous drag slow and that grease is efficiently used that drops of original copy cover clamp is difficult.

Hereinafter, using Fig. 5 and Figure 11~Figure 16, the action to the hinge 100 when original copy cover clamp 13 is closed Illustrate.

As shown in figure 13, in the present embodiment, will be when original copy cover clamp 13 be closed completely i.e. in original copy gland The rotational angle θ of original copy cover clamp 13 when above main body 12 is touched below plate 13 (relative to the original of main body 12 The rotational angle θ of original text cover clamp 13) " 0 ° " is used as, and the situation to be rotated in the opening direction in original copy cover clamp 13 The mode of lower rotational angle θ increase (rotational angle θ turn on the occasion of) defines the rotational angle θ of original copy cover clamp 13.Further, at this In embodiment, the rotational angle θ of the original copy cover clamp 13 when original copy cover clamp 13 is full opening of is " 50 ° ".

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

" electrodeless region " in present embodiment for (A1) " due to original copy cover clamp 13 weight and by rotational pin 130 As center and act on the rotatory force (torque) of revolving member 120 " with (B1) " due to the first spring 150 active force and Using rotational pin 130 as center and act on the rotatory force (torque) of revolving member 120 " region balanced each other.

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

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

The state in " electrodeless (Free-stop) region " is belonged in the side of closure with original copy cover clamp 13 in original copy cover clamp 13 In the case of being rotated on to (direction that the rotational angle θ of original copy cover clamp 13 diminishes), the rotatory force increase of (A1).

It (is connection original copy pressure during side view that this, which depends on resolving into radial direction in the gravity that will act on original copy cover clamp 13, The leading section of cover plate 13 and the direction of rotational pin 130) composition and circumferencial direction (for perpendicular to the side of radial direction during side view To) composition in the case of, the rotational angle θ of original copy cover clamp 13 becomes smaller, then the composition of circumferencial direction be (A1) turn Power becomes bigger.

On the other hand, the state in " electrodeless (Free-stop) region " is belonged to original copy cover clamp 13 in original copy cover clamp 13 In the case of being rotated up in the side of closure, revolving member 120 is relative to box component 110 using right side apparent time to turn clockwise Mode rotate, and revolving member 120 the first cam part 121b and the first sliding block 140 contact protrusion 141a contact site Change, the first sliding block 140 is depressed and moved downwards (reference picture 12 and Figure 14).

Moved downwards by the first sliding block 140, so that the first spring 150 is compressed, (total length of the first spring 150 becomes It is short), the active force increase of the first spring 150, the rotatory force increase of (B1).

As a result, when original copy cover clamp 13 belongs to " electrodeless (Free-stop) region ", turn of original copy cover clamp 13 Even if dynamic angle, θ changes, the rotatory force of (A1) and the rotatory force of (B1) still balance each other.It is more tight, to work as original copy When cover clamp 13 belongs to " electrodeless (Free-stop) region ", even if the rotational angle θ of original copy cover clamp 13 changes, (A1) mode that rotatory force and the rotatory force of (B1) still balance each other, presets the first cam part 121b and contact protrusion 141a shape.

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

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

When original copy cover clamp 13 belongs to " drop zone ", operator from the case that original copy cover clamp 13 is let go, Original copy cover clamp 13 is due to deadweight (being the difference of the rotatory force and the rotatory force of (B1) of (A1) for closely) in closure Side is rotated up.

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

But, as shown in figure 14, when original copy cover clamp 13 belongs to " drop zone ", even if original copy cover clamp 13 Rotational angle θ changes, and the position relative to the first sliding block 140 of box component 110 will not also change.It is more tight For ground, with when original copy cover clamp 13 belongs to " drop zone ", even if the rotational angle θ of original copy cover clamp 13 becomes Change, relative to the mode that does not also change of position of the first sliding block 140 of box component 110, preset the first cam part 121b and contact protrusion 141a shape.

As a result, when original copy cover clamp 13 belongs to " drop zone ", the rotatory force of (B1) essentially becomes zero, (A1) rotatory force is more than the rotatory force of (B1).

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

Therefore, the state for belonging to " drop zone " in original copy cover clamp 13 with original copy cover clamp 13 turns on the direction of closure In the case of dynamic, revolving member 120 is rotated relative to box component 110 by right side apparent time in the way of turning clockwise, and is turned The the second cam part 121c and the contact surface 160a of the second sliding block 160 of dynamic component 120 contact site change, the second sliding block 160 are depressed and move downwards (reference picture 5, Figure 12 and Figure 15).

When the second sliding block 160 is moved downwards, due to be applied to the outer peripheral face of the second sliding block 160 with The drag effect of the viscous drag of grease in the contact portion of the inner peripheral surface of second accommodating chamber 119 is in the second sliding block 160.

Therefore, when original copy cover clamp 13 belongs to " drop zone ", the part of the rotatory force of (A1) by due to The resistance of the viscous drag of grease and be cancelled, and the slowing of being rotated on the direction of closure of original copy cover clamp 13 (being alleviated).

Hereinafter, using Figure 52, Figure 58 and Figure 65, the action to the hinge 500 when original copy cover clamp 53 is closed Illustrate.

In the present embodiment, it will be connect when original copy cover clamp 53 is closed completely below original copy cover clamp 53 The rotational angle θ of original copy cover clamp 53 when above main body 52 is contacted (relative to the original copy cover clamp 53 of main body 52 Rotational angle θ) be used as " 0 ° ", and to be rotated in the opening direction in original copy cover clamp 53 in the case of rotational angle θ The mode of increase (rotational angle θ turn on the occasion of) defines the rotational angle θ (reference picture 52) of original copy cover clamp 53.

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

" electrodeless (Free-stop) region " in present embodiment for (A5) " due to original copy cover clamp 53 weight and Using rotational pin 530 as center and act on the rotatory force (torque) of main box component 510 " with (B5) " due to the first spring 549 active force and rotational pin 530 as center and acted on into the rotatory force (torque) of main box component 510 " balance each other Region.

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

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

The state in " electrodeless (Free-stop) region " is belonged in the side of closure with original copy cover clamp 53 in original copy cover clamp 53 In the case of being rotated up, the rotatory force increase of (A5).

On the other hand, the state in " electrodeless (Free-stop) region " is belonged to original copy cover clamp 53 in original copy cover clamp 53 In the case of being rotated up in the side of closure, (auxiliary box body component 560 is relative relative to main revolving member 520 for main box component 510 In secondary revolving member 570) rotated by right side apparent time in the way of turning clockwise, the first cam of main revolving member 520 Portion 521a and the contact surface 541a of the contact site 541 of the first sliding block 540 contact site change, thus the first sliding block 540 Moved up in the side for submerging the inside to the first accommodating chamber 511.

Moved by the first sliding block 540 on the direction for submerging the inside to the first accommodating chamber 511, so that the first bullet Spring 549 is compressed (total length of the first spring 549 shortens), and the active force increase of the first spring 549, so that the rotation of (B5) Power increases.

As a result, when original copy cover clamp 53 belongs to " electrodeless (Free-stop) region ", turn of original copy cover clamp 53 Even if dynamic angle, θ changes, the rotatory force of (A5) and the rotatory force of (B5) still balance each other.It is more tight, with when original Original text cover clamp 53 belong to " electrodeless (Free-stop) region " even if when original copy cover clamp 53 rotational angle θ change, (A5) mode that rotatory force and the rotatory force of (B5) still balance each other presets the first cam part 521a and contact site 541 Shape.

Therefore, when original copy cover clamp 53 belongs to " electrodeless (Free-stop) region ", in operator from original copy gland In the case that plate 53 is let go, the rotational angle θ of original copy cover clamp 53 is kept.

As a result, when original copy cover clamp 53 belongs to " drop zone ", the rotatory force of (B5) essentially becomes zero, (A5) rotatory force is more than the rotatory force of (B5).

When original copy cover clamp 53 belongs to " drop zone ", the second cam part 571a contacts of secondary revolving member 570 In the contact surface 591 of the second sliding block 590.

Therefore, the state for belonging to " drop zone " in original copy cover clamp 53 with original copy cover clamp 53 turns on the direction of closure In the case of dynamic, auxiliary box body component 560 is rotated relative to secondary revolving member 570 by right side apparent time in the way of turning clockwise, And the second cam part 571a and the contact surface 591 of the second sliding block 590 of secondary revolving member 570 contact site change, because And the second sliding block 590 is moved up in the side for submerging the inside to the second accommodating chamber 561.

When the second sliding block 590 is moved on the direction for submerging the inside to the second accommodating chamber 561, due to It is applied to the grease of the contact portion of the outer peripheral face (four sides) of the second sliding block 590 and the inner peripheral surface of the second accommodating chamber 561 Viscous drag drag effect in the second sliding block 590.

Therefore, when original copy cover clamp 53 belongs to " drop zone ", the part of the rotatory force of (A5) by due to The resistance of the viscous drag of grease and be cancelled, thus the slowing of being rotated on the direction of closure of original copy cover clamp 53 (being alleviated).

As a result, because original copy cover clamp 53 is gently contacted with above main body 52, can be slowly and reliable Ground closure original copy cover clamp 53.

Further, operator's original copy cover clamp 53 dominated by hand and make in the opening direction original copy cover clamp 53 rotate In the case of, the second sliding block 590 to lipophobic viscous drag by the active force of second spring 599 from second because be open The side that portion 561a is protruded is moved up, so can keep " pair rotation when original copy cover clamp 53 belongs to " drop zone " Second cam part 571a of component 570 is contacted with the state of the contact surface 591 of the second sliding block 590 ".
