Description

  The present invention relates to a component mounting structure and an image forming apparatus having the component mounting structure.

  Conventionally, an image forming apparatus such as a copying machine, a fax machine, a printing apparatus, and a multi-function machine having a plurality of functions among them has been used. Inside the image forming apparatus, there are provided electric wires (wire harnesses) that supply power to the fixing device and the recording paper conveyance motor and transmit control signals to various locations in the apparatus.

  In Patent Documents 1 and 2, the electric wire provided in the image forming apparatus may be caught in the gear and may break or damage the gear. In view of the fact that noise may be given to the signal that is sent to the electric wire, there is a possibility that such a situation may occur in the portion of the bending (deflection) that occurs between the holding mechanism that holds the electric wire and the holding mechanism. Focusing on the point that must be avoided, the amount of bending that occurs in the electric wire can be adjusted.

In the techniques of Patent Documents 1 and 2, in both cases, the holding mechanism for holding the electric wire is moved from the original electric wire path so that the electric wire path becomes extra long before and after the holding mechanism. The bending of the electric wires at places other than the vicinity of the holding mechanism is eliminated, and the electric wires are gathered to the neighboring places by the amount of the bending, so that the bending of the electric wires is eliminated.
JP-A-4-11498 JP-A-9-289382

  However, the conventional techniques disclosed in Patent Documents 1 and 2 require a moving mechanism that moves the holding mechanism that holds the electric wire, which increases the number of parts and complicates the mechanism configuration.

  Such a problem is not limited to the image forming apparatus, and is a problem common to electric devices having electric wires.

  The present invention has been made in view of this point, and an object of the present invention is to reduce the number of parts and to adjust the bending of an electric wire included in an electric device without complicating the mechanism configuration. .

  The invention according to claim 1 is a component mounting structure including a mounting structure of the electric device and a component of the electric device mounted on the mounting structure, the mounting structure being mounted on the mounting structure. This is a component mounting structure in which an electric wire of the electronic device is clamped by the component.

  With this configuration, in the component mounting structure configured by the mounting structure of the electrical device and the components of the electrical device mounted on the mounting structure, the mounting structure and the component mounted on the mounting structure As a result, the electric wire of the electronic device is clamped.

  Therefore, although the number of parts is small and the configuration is simple, the amount of bending before and after the location where the wiring is pinched is appropriately distributed, and then the wire is fixed by pinching, and the bending of the wire is distributed. By fixing to the state, the bending of the electric wire can be adjusted.

  The component mounting structure according to claim 2, wherein at least one of the mounting structure for sandwiching the electric wire and at least one of the components, the electric wire moves due to friction generated between the electric wire and the electric wire. The component mounting structure according to claim 1, further comprising a friction member that suppresses this.

  If it is this structure, the said electric wire will move by the friction which arises between the said electric wire and a friction member in the contact | abutting location with the said electric wire in the said mounting structure and the said components which clamp the said electric wire. It is suppressed.

  In this way, even if the electric wire is pinched with a relatively weak force, the movement of the electric wire due to friction is surely suppressed, and the force for pinching the electric wire is weakened, and the damage to the electric wire due to the pinching is reduced. Can be reduced.

  The component mounting structure according to claim 3, wherein at least one of the mounting structure that sandwiches the electric wire and the component is in contact with the electric wire, the electric wire moves by abutting against the electric wire. It is a component attachment structure of Claim 1 or 2 provided with the protrusion part to suppress.

  If it is this structure, in the contact | abutting location with the said electric wire in at least any one of the said mounting structure and the said components which clamp the said electric wire, it will be suppressed that the said electric wire moves when a projection part strikes against an electric wire. .

  In this way, it is possible to easily suppress the movement of the electric wire and maintain the state in which the bending is desired to be adjusted.

  The component mounting structure according to claim 4, wherein the electric device has a configuration of interfering with the electric wire in at least one of physical, mechanical, chemical, and electrical modes, and the protrusion is The component mounting structure according to claim 3, wherein the component mounting structure is formed in a shape that is inclined in a direction away from the configuration of the two directions in which the electric wires extend.

  In this way, the protrusion hits the electric wire in the direction away from the configuration that interferes with the electric wire, and the electric wire can be moved relatively easily in the direction of moving away, but the movement in the approaching direction is reliably suppressed. As a result, it becomes possible to easily and reliably adjust the deflection, and the convenience is improved.

  Note that “interfering” means that the function of one of the configuration and the electric wire is impaired due to the influence of the other. By “going away”, such interference is less likely to occur.

  In the component mounting structure according to claim 5, the protrusions are provided at two different locations in the direction in which the electric wire extends, and the two protrusions are in directions away from the other protrusions, respectively. The component mounting structure according to claim 4, wherein the configuration is between the two locations.

  If it does in this way, there is no bending between the above-mentioned two projection parts, and it can be facilitated so that the bending of the electric wire can be gathered outside the two places, and the bending is thus adjusted. Thus, it is possible to reliably fix the generated trillion pair, thereby easily and reliably avoiding the occurrence of interference between the configuration and the electric wire.

  The configuration may be the component or a part thereof.

  The component mounting structure according to claim 6, wherein the friction member or the protrusion is provided at two different locations in the direction in which the electric wire extends, and the electric wire is bent between the two locations. 4. The component mounting structure according to claim 2, wherein the notch is formed in at least one of the component and the mounting structure.

  If it does in this way, while moving an electric wire will be controlled in two places, the bending of the said electric wire made between the two places will enter into a notch part, collect bending between two places, and two places It is possible to prevent the occurrence of inconvenience due to the bending outside.

  A seventh aspect of the present invention is an image forming apparatus that is the electric device including the component that constitutes the component mounting structure according to any one of the first to sixth aspects and the mounting structure.

  With such an image forming apparatus, it is possible to realize an image forming apparatus capable of adjusting the deflection of an electric wire without reducing the number of components and complicating the configuration.

  ADVANTAGE OF THE INVENTION According to this invention, the electrical equipment which can perform bending adjustment of an electric wire can be implement | achieved, without increasing a number of parts and making a structure complicated.

  Hereinafter, a copying machine 1 according to an embodiment of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing a copying machine 1 according to an embodiment of the present invention.

  The copying machine 1 includes a sheet feeding unit 1a for stacking recording sheets on which image formation is performed, a sheet feeding roller 1b for conveying the recording sheet to a downstream side from the sheet feeding unit 1a on a conveying path formed in the copying machine 1, and the like. 1, an image forming unit 1 c that forms a toner image on a conveyed recording sheet (illustrated by reference symbol P in FIG. 1), and a toner image of the recording sheet P formed by the image forming unit 1 c on the recording sheet P A fixing unit 1d for fixing and a discharge unit 1e for discharging the recording paper P subjected to fixing processing by the fixing unit 1d are provided.

  The copying machine 1 is provided with a cooling fan 100 indicated by a two-dot chain line in FIG. 1, and this cooling fan 100 is a metal frame (not shown) provided on the back of the copying machine 1 (in FIG. 2). A function of preventing the fixing unit 1d from generating too much heat by sucking outside air into the copying machine 1 from the outside of the copying machine 1 is provided.

  FIG. 2 is a diagram illustrating the metal frame 1f to which the cooling fan 100 is attached. 2, the metal frame 1f on the back side of the copying machine 1 is shown as viewed from the viewpoint position on the front side of the copying machine 1 in the same manner as the viewpoint position in FIG.

  In FIG. 2, a configuration indicated by reference numeral 200 is a holder 200 that houses the cooling fan 100 and fixes it to the metal frame 1f. The holder 200 is provided on the metal frame 1f. The holder 200 will be described in detail with reference to FIG.

  FIG. 2 shows an electric wire 300 wired to the copying machine 1. The electric wire 300 is an electric wire that electrically connects components provided in the copying machine 1. The electric wire 300 is passed between the cooling fan 100 and the holder 200 described above, and the passed electric wire 300 is held between the cooling fan 100 and the holder 200. Thus, the electric wire 300 is wired inside the copying machine 1.

  The electric wire 300 may be connected to the cooling fan 100, may be connected to the fixing unit 1d (see FIG. 1), may be connected to other devices, and the like. It may be connected to a plurality of devices. Further, the electric wire 300 may be a power supply line that supplies power, a signal line that communicates signals, or a combination of the power supply line and the signal line. May be.

  FIG. 3 is a view showing the cooling fan 100 and the holder 200. In this figure, the viewpoint position is moved obliquely from the viewpoint position of FIG. 2 to the lower left, and the cooling fan 100 and the like are viewed obliquely, and the vicinity of the cooling fan 100 is enlarged.

  The holder 200 has an upright plate 200A and an upright plate 200B, and holds the cooling fan 100 to the metal frame 1f by pressing the cooling fan 100 with the upright plates 200A and 200B.

  In addition, in the holder 200 of FIG. 2, it is shown that there is a member on the back side (the positive direction side in the x direction) of the standing plate 200A, but this is the bottom plate of the holder 200, and the viewpoint of FIG. This is not visible in position.

  The cooling fan 100 is accommodated in the holder 200 with a side plate 100s (a part of a portion indicated by a two-dot chain line for convenience of illustration) in contact with the standing plate 200A. The claw portions 201a and 201b hold down the side plate 100s from above to fix the cooling fan 100.

  Opposite to the side plate 100s, the holder 200 is also provided with a side plate 100Bs on the front side of FIG. 3, and the side plate 100Bs abuts on the standing plate 200B and is pressed by a claw portion of the standing plate 200B. (Not shown in FIG. 2).

  Thus, the cooling fan 100 is fixed inside the holder 200 by the standing plates 200A and 200B, and thereby the cooling fan 100 is attached to the metal frame 1f.

  In addition, the holder 200 fixes the cooling fan 100 at a fixed position in this way, so that the air in the vicinity of the cooling fan 100 can be generated so that the fan of the cooling fan 100 can smoothly generate an air flow. There is also a function to secure a flowing passage.

  The electric wire 300 shown in FIG. 2 is passed between the side plate 100s of the cooling fan 100 and the upright plate 200A as shown in FIG.

  The standing plate 200A is made of an elastic resin member, and is provided at a close position with almost no gap between the side plate 100A and the side plate 100s. Due to elasticity, the standing plate 200A bends when the upper end is pushed to the right back in FIG. 3 (positive direction in the x direction). If the standing plate 200A is bent in this manner, the gap between the side plate 100s and the side plate 100s increases. The thickness and material of the standing plate 200 </ b> A are selected so that the standing plate 200 </ b> A bends to such an extent that it can be passed through the electric wire 300 into the expanded gap.

  If the erected plate 200A that has been pushed and bent is released and no force is applied, the erected plate 200A returns to the upright state as shown in FIG. 3 and comes into contact with the cooling fan 100 again. , And the standing plate 200A is sandwiched between the cooling fan 100 and the electric wire 300 to fix it.

  The state as shown in FIG. 3 in which the standing plate 200A is upright without applying any force to the upper end of the standing plate 200A is hereinafter referred to as a “normal state” and is erected with force. A state where the plate 200A is bent to widen the gap between the standing plate 200A and the cooling fan 100 is referred to as an “open state”.

  The standing plate 200 </ b> A includes rib portions 202 a and 202 b that fix the sandwiched electric wire 300 when the electric wire 300 is sandwiched between the cooling fan 100.

  FIG. 4 is a diagram showing a detailed configuration of the rib portion 202a. Since the rib portions 202a and 202b have the same configuration, the rib portion 202a will be described here for explanation.

  4A is a view of the standing plate 200A as viewed from above the cooling fan 100 and its holder 200 (on the positive side in the z direction), and the standing plate 200A standing on the holder 200. FIG. The electric wire 300 is passed between the cooling fan 100 and the electric wire 300 is sandwiched between the two.

  FIG. 4B is an enlarged view of the vicinity area Va1 of the rib portion 202a in FIG. 4A, and FIG. 4C is a further vicinity area Va2 of the rib portion 202a in Va1. Is an enlarged version.

  As shown in FIG. 4 (c), the rib portion 202a is a protrusion configured to protrude from the standing plate 200A toward the electric wire 300, and extends in a direction perpendicular to the drawing (z direction). It is provided on the plate 200A (see FIG. 3).

  When the standing plate 200A returns to an upright state (normal state) by the elastic force and the electric wire 300 is sandwiched between the cooling fan 100, the rib portion 202a presses the electric wire 300 (FIG. 4B). reference). Thereby, even if it is going to move the electric wire 300 to the up-down direction (y direction) of a figure, this rib part 202a is hooked on the electric wire 300, and the electric wire 300 cannot move.

  And the other rib part 202b is pressed also in this way to the electric wire 300 similarly to the rib part 202a (refer Fig.4 (a)).

  Thus, when the standing plate 200A is changed from the open state to the normal state, the rib portions 202a and 202b press the electric wire 300 and fix the electric wire 300.

  In such a copying machine 1, it is possible to adjust the bending of the electric wire 300 as follows. For example, when the copying machine 1 is manufactured in a factory, the bending adjustment is performed when the cooling fan 100 is attached to the holder 200 of the copying machine 1 or when the copying machine 1 is shipped to the user. Sometimes done.

  First, the adjuster pushes and bends the standing plate 200A to be in an open state, and passes the electric wire 300 through a gap between the standing plate 200A and the cooling fan 100 that are widely opened.

  Then, the adjuster moves the electric wire 300 in the linear direction of the electric wire 300, that is, the direction in which the electric wire 300 extends, that is, the vertical direction (y direction) in FIG. By moving the electric wire in this manner, the amount of bending of the electric wire 300 before and after the upright plate 200A in the direction is adjusted. That is, the length of the electric wire 300 on the upper side of FIG. 4 from the upright plate 200A and the length of the lower side of the electric wire 300 are allotted, and the amount of bending generated in the electric wire 300 above the upright plate 200A and the upright plate 200A. And the amount of deflection that occurs below.

  Here, in this distribution, when there is a conveyance roller or the like that may entrain the electric wire 300 at a position above the upright plate 200A, and when it is desired to avoid the electric wire 300 from passing therearound, the upper distribution is performed. In addition, when the transport rollers and the like are in the lower part and it is desired to avoid the electric wire 300 passing through the lower part, the lower distribution is reduced.

  In addition to the transport roller, for example, the cooling fan 100 has a movable portion, and the electric wire 300 may be caught in the movable portion. Therefore, it is desirable to avoid the electric wire 300 from passing through such a place. Further, in the member such as the cooling fan 100, the burrs cannot be completely removed and remain to some extent, and the electric wires 300 strike the remaining burrs, so that the electric wires 300 are rubbed to cover the electric wires 300. There is a risk of damage, and it is desirable to prevent the electric wire 300 from passing near such a place. Furthermore, even when the electric wire 300 touches the fixing unit 1d (FIG. 1), the coating of the electric wire 300 may be damaged by the heat of the fixing unit 1d. The above distribution is performed so that the bending of the wires can be avoided where it is not desirable for these wires 300 to pass.

  And if an adjuster can distribute appropriately, it will be adjusted appropriately by rib part 202a, 202b by releasing the erected board 200A which had been pushed and bent, and returning it to the original upright state (normal state). The electric wire 300 is fixed in the state.

  In this way, it is possible to realize the copying machine 1 that can adjust the deflection of the electric wire 300 while avoiding an increase in the number of parts.

  A modification of the present embodiment will be described below.

  (A) FIG. 5 is a view showing a rib portion 203a according to a modification.

  Unlike the rib part 202a described above, the rib part 203a is made of a material different from the material of the main body of the standing plate 200A1. And the material which comprises this rib part 203a is chosen so that the friction between the electric wires 300 becomes larger than the material which constitutes the standing plate 200A1 main body.

  For example, the rib part 203a can be comprised with a hard urethane-like sponge material. The rib portion 203a is preferably an elastic member.

  In this way, when the standing plate 200A1 is returned to the normal state, that is, the upright state, even if the force that the rib portion 203a urges the cooling fan 100 is relatively weak, the rib portion 203a reliably connects the electric wire 300. Can be fixed. As a result, the force by which the rib portion 203a urges the cooling fan 100 can be made relatively weak, and the rib portion 203a can be prevented from damaging the electric wire 300.

  (B) FIG. 6 is a diagram illustrating a fixing portion 204a according to a second modification. The fixing portion 204a corresponds to the rib portion 202a (or the rib portion 203a in FIG. 5) in the above description, and fixes the cooling fan 100. 6 does not protrude from the main body of the standing plate 200A2.

  The fixed portion 204a is embedded in the main body of the standing plate 200A2, and is configured by a member having a large friction, which is different from the main body of the standing plate 200A2. The standing plate 200A2 has a flat surface in contact with the electric wire 300, and the fixed portion 204a forms part of the flat surface.

  Although this fixing | fixed part 204a does not have a shape which protrudes on standing installation board 200A2, and does not press the electric wire 300 strongly, it is comprised by the material with a big friction produced between the electric wires 300. The electric wire 300 can be fixed similarly to the rib portions 202a and 203a described so far.

  If the fixing portion 204a is configured in this manner, the fixing portion 204a does not protrude from the standing plate 200A2 to the electric wire 300, so that the occurrence of damage to the electric wire 300 can be reduced.

  In FIG. 6, the fixing portion 204a is shown to have a certain thickness in the left-right direction (x direction) in the drawing, but it does not necessarily have to have such a thickness. For example, the fixing portion 204a may be a simple film formed by applying a liquid to the standing plate 200A2. At this time, as shown in FIG. 6, it is not always necessary to provide a groove for providing the fixing portion 204a in the standing plate 200A2. In addition, the fixing portion 204a is not necessarily made of a material different from that of the main body of the standing plate 200A2, and for example, a surface that increases specific friction on a part of the plane where the standing plate 200A2 contacts the electric wire 300 The fixing portion 204a may be configured as a region of the surface of the standing plate 200A2 that has been subjected to processing (for example, filed) and subjected to surface processing.

  (C) FIG. 7 is a diagram illustrating the claw portions 200Ba and 200Bb according to the third modification.

  In the description of the embodiment, FIG. 2 shows that the holder 200 is provided with another upright plate 200B facing the upright plate 200A. As shown in FIG. 7, the standing plate 200B is provided with claw portions 200Ba and 200Bb. The standing plate 200B having the claw portions 200Ba and 200Bb will be described below as a modification.

  The standing plate 200B has a configuration in which the intermediate portion in the y direction is removed from the standing plate 200A described in detail with reference to FIGS. 1 to 4 except for the ends where the claw portions 201a and 201b of the standing plate 200A are provided. The space 200Bx shown in the standing plate 200B corresponds to the removed portion, and the claw portions 200Ba and 200Bb in the standing plate 200B correspond to the end portions left after the removal.

  The claw portions 200Ba and 200Bb can be pushed and bent to the left side (the negative direction in the x direction) in the drawing to widen the gap between the cooling fan 100, and the gap is thus widened. In the open state, the electric wires 300B can be passed between the claw portions 200Ba and 200Bb and the cooling fan 100, respectively.

  The claw portions 200Ba and 200Bb of the standing plate 200B are provided with rib portions (or fixing portions) in any of the modes described so far (not shown), and therefore, the original upright state ( When the claw portions 200Ba and 200Bb are returned to the normal state), the electric wire 300B is sandwiched between the claw portions 200Ba and 200Bb and the cooling fan 100, and the claw portions 200Ba and 200Bb are clawed by the rib portions in the same manner as described above. The electric wire 300B can be fixed at the portions 200Ba and 200Bb.

  Next, how to adjust the bending of the electric wire 300B by such a standing plate 200B will be described. However, the adjustment mode described here is an example, and another example will be described later.

  By fixing the electric wire 300B with the claw portion 200Ba, the distribution of the bending amount of the electric wire 300B above and below the claw portion 200Ba in FIG. 7 can be adjusted, and the electric wire 300B is fixed with the other claw portion 200Bb. Accordingly, the distribution of the amount of bending of the electric wire 300B at the upper and lower portions of the claw portion 200Bb can be adjusted, so that both the claw portion 200Ba and the claw portion 200Bb allow the upper portion of the claw portion 200Ba and the claw portions 200Ba, 200Bb. According to this standing plate 200B, it is possible to distribute the amount of bending caused by the electric wire 300B at three locations, the location of the space 200Bx between and the location below the claw portion 200Bb.

  In the copying machine 1, the movable part (fan or the like) of the cooling fan 100 and the space 200Bx are reliably separated by the side plate 100Bs, etc., so that the electric wire 300B bends around the space 200Bx. Even if the deflection protrudes from the space 200Bx to the left side (the negative direction side in the x direction) and hangs downward (the negative direction side in the z direction), the deflection accumulates in the lower left portion of the space 200Bx. It seems to be safe. For this reason, the electric wire 300B is adjusted so that bending occurs only in the space 200Bx between the claw portions 200Ba and 200Bb and the space 200Bx. In other words, the loosened portion of the electric wire 300B does not loosen outside the claw portions 200Ba, 200Bb (on the side away from the space 200Bx), that is, above the claw portion 200Ba or below the claw portion 200Bb. When the bending adjustment is performed with the portions 200Ba and 200Bb opened, all are collected between the claw portions 200Ba and 200Bb.

  In this way, the bending state can be adjusted accurately.

  In such a standing plate 200B, the rib portion does not significantly suppress the movement of the electric wire 300B from the upper side of the claw portion 200Ba or the lower side of the claw portion 200Bb into the space 200Bx, and in the reverse direction. It is preferable that the movement of the electric wire 300 </ b> B is strongly suppressed when it is returned. Next, the rib part which exhibits such an action will be described.

  (D) For example, as a rib portion in which triangular prisms are arranged to form a saw-like shape, a rib portion having such an action can be formed, and a fourth example of a simplified structure using one triangular prism As shown in FIG.

  FIG. 8 is a view showing a rib portion 205a according to a fourth modification.

  This rib portion 205a is provided on the claw portion 200Ba of FIG. 7, and this rib portion 205a is shown by a broken line obliquely toward the lower side (the negative direction in the y direction) of the space 200Bx. It protrudes in the direction of the arrow shown, and the electric wire 300B is pressed in this arrow direction while the electric wire 300B is recessed in this arrow direction and enters the electric wire 300B.

  As a result, the electric wire 300B can be easily moved in the forward direction indicated by the arrow L, but the claw portion 200Ba is moved to the left side of the figure (the negative direction in the x direction) in the direction opposite to the arrow L direction. The electric wire 300B cannot be moved unless it is pushed and moved (unless it is opened).

  In this way, it is possible to easily adjust, and to realize a rib portion that securely fixes the adjusted state.

  In this way, the rib portion 205a is formed so that the arrow L direction is the forward direction, but the other rib portion provided in the claw portion 200Bb is formed so that the reverse direction to the L direction is the forward direction. The

  (E) In the description of FIG. 8, the electric wire 300B is not loosened outside the claw portions 200Ba and 200Bb (on the side away from the space 200Bx), that is, above the claw portion 200Ba and below the claw portion 200Bb. In addition, it has been explained that the loose portions are all collected between the claw portions 200Ba and 200Bb when the claw portions 200Ba and 200Bb are opened to adjust the deflection, but conversely, the claw portions 200Ba, Adjustment may be performed so that no looseness remains between 200 Bb. A configuration shown in FIG. 9 can be given as a preferable configuration when such adjustment is performed.

  FIG. 9 is an explanatory view showing rib portions 206a and 206b suitable for adjustment so that no looseness remains between the claw portions 200Ba and 200Bb.

  The rib portions 206a and 206b have the same configuration as described above, but the positive direction in the y direction away from the space 200Bx is the forward direction of the claw portion 200Ba, and the other claw portion 200Ba also has the space 200Bx. The difference is that the negative direction of the y direction, which is the direction away from the direction, is the forward direction.

  With such a configuration, when the electric wire 300B is bent between the rib portions 206a and 206b, the electric wire 300B may be caught in the fan of the cooling fan 100. When it is preferable that the bending is less likely to occur, the bending between the rib portions 206a and 206b can be easily eliminated, and the state in which the bending is eliminated can be reliably maintained.

  (F) The rib part and the fixing part described above do not necessarily have to be provided on the holder 200 side as described above, and may be provided on the cooling fan 100 side. It is good also as what is provided in both with the fan 100. FIG.

1 is a diagram showing a copying machine 1 according to an embodiment of the present invention. It is a figure which shows metal frame 1f with which the cooling fan 100 was attached.
