Description

  The present invention relates to a document crimping plate opening / closing device suitable for office machines having a document crimping plate such as a copying machine, a printing machine, a facsimile machine, and a scanner, and to an office device equipped with the document crimping plate opening / closing device. .

  This kind of document crimping plate opening / closing device has at least a bottom plate and both side plates raised from both side portions of the bottom plate, an attachment member for attaching the bottom plate to an apparatus body of an office device, an upper plate, and the upper plate. A supporting member for supporting a manuscript pressure-bonding plate having both side plates suspended from both side portions and rotatably attached to both side plates of the mounting member via hinge pins; and a mounting member and a supporting member For example, a compression spring made of a compression spring.

  The elastic means is originally opened without feeling the weight when the original cover is opened, and does not fall spontaneously even if the hand is released from the original cover within a predetermined opening angle range (about 20 ° to 60 °). It has a function to support. However, a change in elasticity over time is inevitable, and the function that it should have is hindered.

  As shown in Patent Documents 1 and 2 below, most of the elastic force adjusting means is used to adjust the adjustment member applied to one end of the elastic means using a tool such as a screwdriver from the axial direction of the elastic means. The elasticity was adjusted by moving in the axial direction and adjusting the effective length of the elastic means.

  However, the elasticity adjusting means having such a configuration has a problem in that it is difficult to perform the adjusting operation because the document pressing plate opening / closing device must be removed from the apparatus main body or the document pressing plate for adjustment. .

  In view of this, what is described in Patent Document 3 below is publicly known as an adjustment that can be performed on the front side of office equipment.

  In this patent document 3, an adjustment member provided on a spring receiving member and receiving elastic means is composed of two first disks and a second disk each having a cam convex part and a cam concave part. The second disk is configured to be rotatable, and an operation protrusion is protruded from the second disk to the outside of the spring receiving member. The operator presses the operation protrusion on the front side of the document crimping plate opening / closing device with a finger. By rotating the two disks stepwise, the first disk is moved in the vertical direction to adjust the elasticity of the elastic means.

  However, according to the elastic force adjusting method of the elastic means described in Patent Document 3, the operator is at the front side of the office equipment and presses the operating projection with the finger to rotate left and right, so that the adjusting operation is easy. However, there is a new problem that fine adjustment is difficult due to adjustment with a finger. That is, since the spring load of the elastic means is applied to the second disk, it is not easy to rotate and adjust the second disk with a finger, and the adjustment width is limited to the number of cam stages. There is a problem that fine adjustment is difficult.

  The change in elasticity of the elastic means over time is closely related to the deterioration of the elastic means, the environment in which the office equipment is placed, the frequency of opening and closing the original cover, and the change in the friction torque of the friction means over time. There is a problem that it is related and cannot be sufficiently handled by stepwise adjustment.

The adjusting member 26 is attached to the first swinging spring receiving member 17 in a direction intersecting the elastic means 19. An insertion hole 29 for inserting the tip of a tool 28 that is engaged with the head portion 26a of the adjustment member 26 and rotated is provided.

  In the following, functions and effects of the document crimping plate opening / closing device A and the office equipment 1 according to the first embodiment will be described.

  In the closed state with respect to the document pressing plate 3 and the apparatus main body 2, as shown in FIG. 4, the elastic means 19 of the urging means 16 is the second adjustment plate 24 in the first swinging spring receiving member 17. And the second swinging spring receiving member 18 are compressed to the maximum, but the original pressing plate 3 is generated around the first hinge pin 9 via the support member 8 rather than the elasticity at that time. Since the rotational torque is superior, the original cover 3 is pressed onto the contact glass 2 a of the apparatus body 2. Therefore, in the case of a thin document, the document is pressed onto the contact glass 2a.

  Next, when holding the front side of the original cover 3 by hand and opening it upward, the weight of the original cover 3 is first felt, but gradually the elasticity of the elastic means 19 of the biasing means 16 begins to prevail, The person can open the document crimping plate 3 without feeling the weight, and as shown in FIG. 5, the rotational torque of the elastic means 19 can be obtained even when the hand is released from the document crimping plate 3 at an opening angle of about 30 °. Due to the synergistic effect of the friction torques of the friction means 12 and 12, the friction means 12 is held in the open state without falling naturally.

  Therefore, it is possible to exchange the document with both hands. This self-standing opening angle is usually between approximately 20 ° and 60 °.

  When the original is a thick original such as a book, the original crimping plate 3 is opened at a necessary angle, the thick original 30 is placed on the contact glass 2a, and the original crimping plate 3 is closed. 6 hits the corner of the thick original 30, so that when the pressure is further applied and pushed down, the original pressing plate 3 and the lift member 13 together with the elastic force of the elastic means 19 support the second hinge pin 10 as shown in FIG. By inverting the cover, the upper surface of the thick original 30 is covered substantially horizontally, so that external light can be prevented from entering the apparatus main body 2 through the contact glass 2a, and clear copying can be performed. To do.

  When the lift member 13 is reversed, as described above, the lift member 13 is reversed with the second hinge pin 10 as a fulcrum, and at this time, the actuating member 14 that pivots around the second hinge pin 10 serves as the second swinging spring receiving member 18. Since the elastic means 19 is compressed by pressing, when the copy is finished and the hand is released from the original pressure plate 3, the elastic means 19 moves the lift member 13 through the second swinging spring receiving member 18 and the operating member 14. By rotating, the original cover 3 automatically or easily returns to its original position without applying excessive force.

  When the elasticity of the elastic means 19 is adjusted by using the elasticity adjusting means 21, particularly as shown in FIGS. 7 and 8, when the document crimping plate 3 is fully opened, the first of the document crimping plate opening / closing device A is opened. Since the front side of the swinging spring receiving member 17 faces the front surface and the insertion hole 29 for operating the adjusting member 26 faces the front side, it is on the front side of the office equipment 1 without moving the apparatus main body 2, for example in FIG. As shown, the tool 28 made of a wrench is inserted through the insertion hole 29 and engaged with the head 26a of the adjustment member 26, so that the adjustment member 26 can be rotated in either the left or right direction. By rotating the second adjustment plate 24 to the left and right via the piece 25, the second adjustment plate 24 moves up and down due to the mutual contact of the cam portion with the first adjustment plate 23. This second tone Those capable of controlling the elastic force of the elastic means 19 that press on the plate 24.
