Description

  The present invention relates to a cap applicable to an exterior portion of a mechanical apparatus such as a copying machine, a facsimile machine, a printer, and an image forming apparatus such as a multifunction machine having a plurality of mechanisms, and an image forming apparatus using the cap.

  In an exterior part used in a mechanical apparatus such as an electrophotographic image forming apparatus, a screw is used to fasten the exterior part itself to the structure of the apparatus main body. At this time, it is not preferable in terms of appearance quality and design if the portion where the screw fastening is performed is exposed to the outside. Therefore, the screw fastening part is placed one step deeper, and a cap that is flush with the external appearance surface is snap fitted (the convex part provided on the part is fitted into the concave part on the receiver side using the elasticity of the material and hooked. The assembly method is mechanically fixed). Further, when it is necessary to remove the exterior part from the structural frame for service or the like, it is necessary to push and bend the snap-fit hook structure portion of the cap with a small flat-blade screwdriver to release the engagement and remove it.

In addition, a connector that uses a fastener or the above-mentioned cap for connector connection with a peripheral device and taking into consideration the appearance quality design is used, and is already known (for example, Patent Document 1).
In this technology, when removing the cap, a circular cap with a snap fit is rotated, and the convex side of the snap fit is gradually bent to the release side with a rib that stands inside the hole of the exterior part and removed. Is adopted.

However, with caps attached to conventional exterior parts, the snap-fit convex part on the cap side is fitted into the concave part of the exterior part to release the hook, so the snap fit is pushed and bent with a flat-blade screwdriver to release the engagement. doing. During this removal operation, an excessive force is applied to the snap fit, and the outer surface side of the snap fit may be whitened, damaged, or broken.
In order to avoid this, for example, Patent Document 1 adopts a configuration in which the cap is circular and the snap fit is gradually pushed and bent by rotating, but in this case, the cap shape is limited to a circular shape. The problem that it ends up occurs.

  Furthermore, it is desired to adopt a configuration that allows the operation of attaching the cap to the exterior part using a snap-fit hook structure or removing the cap from the exterior part by releasing the hook with good operability.

  The present invention adopts a configuration that disperses the displacement caused by the release of the snap-fit of the snap fit, and the release of removing the cap from the exterior part can be performed with good operability. Accordingly, an object of the present invention is to provide a cap and an image forming apparatus using the cap that prevent the cap from being whitened, damaged, and broken without being excessively applied by a releasing operation, and not subject to cap shape regulation. .

  In order to achieve the above object, a cap according to the present invention includes a pair of pieces that are bent and displaced at a middle bent portion between each other, and a claw portion that is formed on the pair of pieces and removably engages an exterior product. An operation force receiving portion that receives an operation force for removing the claw portion from the main body. Was provided.

  According to the present invention, when the operation force is received by the operation force receiving portion, the pair of pieces can be bent and displaced at the middle bent portion, and each claw portion of the pair of pieces is engaged with the exterior product according to the bending displacement. Displacement in a direction deviating from the combined state is applied. For this reason, the cap can be easily removed from the exterior product, and the cap does not receive an excessive operating force, so that the cap can be prevented from being whitened, broken or broken.

The cap according to the present invention has the following features.
In short, an operating force receiving portion is provided, and when the operating force receiving portion receives the operating force, bending displacement occurs at the middle folding portion connecting the pair of pieces, and each claw portion of the pair of pieces is connected to the exterior product. Displacement in the direction away from the engaged state is applied. Thereby, the cap can be easily removed from the exterior product, and at that time, it is possible to prevent the cap from being whitened, broken or broken.

Here, a cap according to the present invention and an image forming apparatus using the cap will be described in Embodiment 1.
Note that, in each drawing and embodiment, the same member or a member having the same function is basically denoted by the same reference numeral, and redundant description is appropriately omitted.
FIG. 1 is a diagram illustrating a schematic configuration of a multi-function copying machine (hereinafter simply referred to as an image forming apparatus) that is an image forming apparatus according to the first embodiment.

The image forming apparatus 1 is connected to a communication device such as a facsimile machine (not shown) via a public line, and is connected to a communication device such as a host computer (not shown) via a network. Forming a forming system.
In FIG. 1, a printer unit 100, which is an image forming apparatus main body, basically forms an image according to a general electrophotographic image forming process. In addition, a facsimile function for printing an image received from a public line by a FAX communication unit (not shown), a copy function for printing an image read from the scanner unit 200, and an image from a host computer (not shown). A printer function for printing.

As shown in FIG. 2, the printer unit 100 forms an image according to a general electrophotographic image forming process. In order to realize these functions, the printer unit 100 includes a printer control unit that integrally controls each functional unit, an optical system control unit of an optical system, a temperature control unit of a fixing heater, a transfer paper size detection unit, a paper feed unit presence / absence detection unit, A transfer paper conveyance control unit is included, and these are connected to be able to communicate with each other.
The scanner unit 200 reads a document and sends it to a FAX communication unit (not shown), while sending image information to the printer engine unit during copying. The FAX communication unit transmits the stored image information to the partner communication terminal through the public line, and on the other hand, sends the received image to the printer unit 100 to output it on the transfer paper.

  The post-processing unit 300 includes transfer paper on which print request data from the host computer is printed, transfer paper on which an image read by the scanner unit 200 is output, transfer paper on which facsimile reception data from a facsimile apparatus (not shown) is printed, and the like. To be discharged. The paper feeding unit 500 and the mass paper feeding unit 600 include a paper feeding cassette (not shown) that accommodates transfer paper. The double-sided unit 400 reversely conveys the transfer paper after single-sided printing in order to perform double-sided printing. The manual paper feed unit 700 is for manually feeding transfer sheets one by one. Here, the double-sided unit 400 and the large-volume sheet feeding unit 600 are integrated to form a large-capacity sheet feeding unit 600a.

As described above, the image forming apparatus 1 configures an image forming system by connecting the post-processing unit 300, which is an optional unit, the large-capacity paper feeding unit 600a, and the like to the outer wall of the printer unit 100, which is a main part.
In such a printer unit 100, the frame body 110 on the side surface of the apparatus main body is covered with a right cover 4 as an exterior part. When an optional unit such as a large-capacity paper feeding unit 600a is attached to the printer unit 100, as shown in FIG. 3 (a), a vertically long rectangular cap fitting hole (hereinafter simply referred to as a right cover 4 (exterior portion)). 7) (referred to as a cap hole).

  For example, as shown in FIG. 4, a cap hole 7 is provided on the exterior surface f1 of the printer unit 100, and a terminal 8 for attaching the jig 6001 to the large-capacity paper feeding unit 600a is provided on the frame 110 on the side surface. The reference pin pn is attached and the screw n1 is fastened. Here, when the large-capacity paper feeding unit 600a, which is an optional product, is not attached, the cap hole 7 here is exposed on the surface of the exterior portion with the opening 5 of the cap hole 7 (see FIG. 3B) facing outward. It becomes a state, and the appearance is deteriorated. Therefore, it is necessary to attach a blind cap 6 to the cap hole 7. Further, when connecting a peripheral device to the printer unit 1 of FIG. 1, it is necessary to remove the cap 6 so that the terminal 8 inside can be accessed.

  Here, as shown in FIGS. 4A and 4B, the vertical rectangular cap hole 7 into which the vertical rectangular cap 6 is fitted is bent inward at the upper and lower edges, and is vertically flanged 12. Is formed. The center of these flanges 12 forms a locking edge 121, which is formed to lock the claw portion (locking portion) 11 that is a part of the snap fit 9 on the cap 6 side. As shown in FIG. 4B, the left and right vertical edge portions of the cap hole 7 are bent and formed in a cap-shaped cap receiving portion 122 having a cross section. For this reason, when the cap 6 is fitted in the cap hole 7 and the claw portion 11 of the snap fit 9 is locked to the locking edge 121, the cap 6 is in the back direction shown in FIGS. 4 (a) and 4 (b). It is necessary not to fall into r. Here, the right and left edge portions of the cap 6 are formed to be supported by the cap receiving portion 122. In order to maintain such a fitting shape, the total length L1 of the cap 6 (the distance between the upper and lower claw portions 11) is formed larger than the total length L2 of the cap hole 7 (the distance between the upper and lower flanges 12).

Next, a specific example of the cap 6 will be described with reference to FIGS.
Here, the cap 6a in the first embodiment integrally forms the main body 13 and the support member 14 of the cap. The main body 13 is engaged with a pair of pieces 16a and 16b connected so as to be bent and displaced with each other at the bent portion 15, and is engaged with the right cover 4 which is an exterior portion and is detachably engaged with the pair of pieces 16a and 16b. And a claw part 11 as a part.
Here, each of the pair of pieces 16a and 16b is provided with a bent portion 15 that bends and displaces each other at an intermediate portion in the longitudinal direction of the main body (vertical direction in FIG. 5A). The folded portion 15 is provided so as to divide the pair of pieces 16a and 16b by straight lines, and the back side (the left side in FIG. 5B) facing the support member 14 in the thickness direction is formed in the groove 151. The front side (the right side in FIG. 5B) forms a thin resin hinge 152. Thereby, a pair of piece part 16a, 16b is connected by the bending part 15 so that bending displacement is possible.
As shown in FIGS. 5 (a) and 5 (b), the support member 14 is in the form of a long plate, and upper and lower opposing ends are coupled to the pair of pieces 16a and 16b so as to bridge the folded portion 15 respectively. The two ends are integrally coupled.
5B is set so that the surface side bends at an angle (= θ0) smaller than 180 ° in a free state.

FIG. 6A shows a bending displacement state when such a cap 6a is attached to the cap hole 7. FIG. Here, in a state where the upper and lower end portions eu and ed are pressed up and down, the bent portion 15 is bent at an angle θ1 larger than 180 °.
Then, since the total length L3 of the cap 6a is smaller than the total length L2 of the cap hole 7 (distance between the upper and lower flanges 12), the cap 6a is moved in the direction of the arrow pi in this state, as shown in FIG. Thus, the cap hole 7 is fitted and held. Here, when the pulling of the bent portion 15 in the outward bending direction pf is stopped, the support member 14 acts to apply a return reaction force accompanying the elasticity to the pair of pieces 16a and 16b. For this reason, the middle bent portion 15 is displaced in the return direction pg, and the claw portions 11 of the upper and lower snap fits 9 are respectively displaced in the locking direction pj which is the opposite direction.
FIG. 7 shows a state in which the folded portion 15 is assembled in the cap hole 7 after the claw portion 11 is moved in the return direction pg and the claw portion 11 is moved in the locking direction pj.

  Here, even when the cap 6a is assembled in the cap hole 7, the folded portion 15 maintains a larger angle than the initial state of FIG. For this reason, the support member 14 exerts a force to return to the original state, and the folded portion 15 continues to be applied in the return direction pg, and the upper and lower claw portions 11 of the snap fit 9 continue to be applied in the opposite locking direction pj. That is, the left and right edge portions of the cap 6a are kept pressed toward the cap receiving portion 122 (in the return direction pg direction). At the same time, the upper and lower claws 11 are elastically locked toward the locking edge 121 at the center of the flange 12 (in the locking direction pj). Thereby, shakiness of the cap 6a can be suppressed.

Next, a functional unit that is attached to the main body of the cap 6a and removes the cap from the cap hole 7 will be described.
As shown in FIGS. 6A and 6B, the cap 6a has upper and lower end portions eu and ed as operation force receiving portions for applying an operation force to the main body 13 to remove the claw portion 11 as a locking portion.
When the operation of removing the cap 6 a from the cap hole 7 is performed, the upper and lower end portions eu and ed as the operation force receiving portion on the main body 13 side are in a state of facing the upper and lower flanges 12. The upper and lower end portions eu and ed are formed in advance so as to secure a gap t1 into which a rod-shaped tool such as a minus screwdriver 22 can be inserted with respect to the flange 12.
Therefore, when the cap 6a is removed from the cap hole 7 using the minus driver 22, for example, a pressing force is applied to the upper end eu on the main body 13 side by the minus driver 22. At this time, the bent portion 15 is easily bent by the pressing force applied to the main body 13, and the main body 13 of the cap 6a does not receive an excessive pressing force. In this way, the bent portion 15 is reliably bent, and in accordance with this bending displacement, the respective claw portions 11 of the pair of pieces 16a, 16b are displaced in a direction away from the engaged state with the flange 12 (a member on the exterior product side). To do. This displacement and the elastic displacement when the claw portion 11 is removed from the locking end edge 121 of the flange 12 are added, so that the claw portion 11 can be easily removed from the flange 12 and the body 13 is prevented from being whitened, broken or broken. be able to.

As a molding material for such a cap 3a, for example, a polypropylene (PP) resin can be used, so that a component strong against bending can be obtained, and the bent portion 15 has excellent flexibility. The durability of the cap 6a is improved.
On the other hand, as a molding material of the support member 14, two bodies are molded by using only this as a high-rigidity dissimilar material (for example, an ABS material containing glass). As a result, the rigidity of the support member 14 is further increased, and the shape rigidity can be increased even if the bent portion 15 is present. That is, since the shape rigidity is high even if the body 13 has the bent portion 15, each claw portion 11 of the pair of pieces 16 a and 16 b is elastically urged to the locking end edge 121 of the flange 12 ( Increase and gain momentum), and can be kept stable.
When the cap 6a is removed from the cap hole 7, the access for connecting the optional unit to the terminal 8 in the cap hole 7 is performed thereafter. That is, the terminal 8 in the cap hole 7 is attached with a reference pin pn of a jig 6001 (see FIG. 4A) such as an optional unit such as a large-capacity paper feeding unit 600a or a screw n1. Will be performed.

Next, FIG. 8 shows a modification of the first embodiment in which only the bent portion 15 of the cap 6a of the first embodiment is different. Here, since the configuration other than the folded portion 15a ′ is the same as that of the cap 6a, a duplicate description is omitted.
The cap 6a ′ of FIG. 8 has a back side (left side in FIG. 8) opposite to the support member 14 in the thickness direction in a side view of the folded portion 15a ′ that linearly divides the pair of pieces 16a and 16b. A thin resin hinge 152 ′ is formed, and the front side is formed in the groove 151. That is, the only difference from the cap 6a of the first embodiment is that the groove 151 ′ is arranged on the machine surface side (right side in FIG. 8).
There is a concern that the resin hinge 152 ′ of the folded portion 15 a ′ may be whitened by repeated bending. Here, by taking the configuration of the cap 6a ′, the whitened portion can be placed in a position deeper than the surface, so that there is an advantage that whitening is not noticeable in appearance.

Next, the cap 6b as the second embodiment will be described with reference to FIGS. 9 (a) and 9 (b).
Here, the cap 6b is different from the first embodiment only in the operation force receiving portion for applying an operation force to remove the cap 6b from the cap hole 7 provided in the right cover 4 (exterior portion), and other configurations such as the assembly configuration are the same. Therefore, duplicate explanation is omitted.
As shown in FIGS. 9A and 9B, the cap 6 b has an operation hole 21 in the main body 13 as an operation force receiving portion that applies an operation force to remove the claw portion 11 that is a locking portion to the main body 13. .

The operation hole 21 may be provided between the pair of pieces 16a and 16b, or below or above the middle bent portion 15. Here, the operation hole 21 forms a rectangular opening and is formed over the upper and lower portions of the folded portion 15. The operation hole 21 is formed so that a rod-shaped tool such as a flathead screwdriver 22 can be inserted.
When removing the cap 6b as the second embodiment from the operation hole 21, first, the flat screwdriver 22 is inserted into the operation hole 21 with the upper and lower ends eu and ed held from the outside of the machine (right side in FIG. 9B). . Next, the main body 13 is pulled to the outside of the machine by a flat-blade screwdriver 22 and the middle folded portion 15 is pulled in the bending direction pf, thereby displacing the middle folded portion 15 to a bending angle θ2 larger than 180 °.
Then, the total length L3 of the cap 6b becomes smaller than the total length L2 of the cap hole 7 as in the case shown in FIGS. 6A and 6B used in the first embodiment. The cap 6b in this state can be easily removed from the cap hole 7, and a jig 6001 such as an optional unit such as a large-capacity paper feed unit 600a is attached to the terminal 8 in the opening 5, for example.

Next, the cap 6c as the third embodiment will be described with reference to FIGS. 10 (a) and 10 (b).
Here, the cap 6c is different from the first and second embodiments only in the operation force receiving portion for applying an operation force to remove the cap 6c from the cap hole 7 provided in the right cover 4 (exterior portion). Since they are the same, duplicate explanation is omitted.
As shown in FIGS. 10A and 10B, the cap 6 c that closes the cap hole 7 provided in the right cover 4 (exterior portion) has an operating force for removing the claw portion 11 that is a locking portion on the main body 13. A knob-shaped portion 23 is formed as an operation force receiving portion for applying the pressure.
Here, the knob-shaped portion 23 of the main body 13 is provided on the lower side of the bent portion 15, but may be on the upper side in some cases. The operating force received by the knob-shaped portion 23 can be easily transmitted to the nearby bent portion 15 and the bent portion 15 can be easily bent and displaced. Thus, since the bent part 15 bends reliably, the nail | claw part 11 can be easily removed from the latching edge 121 of the flange 12, and the cap 6c can be removed from the cap hole 7. FIG. At this time, since an excessive operating force does not act, whitening / breakage / breakage of the cap 6c can be prevented.

Further, the knob-shaped portion 23 is pinched by hand to apply an operating force, and the cap 6c can be removed, so that the cap can be easily removed without using a tool such as a flathead screwdriver 22 (without preparation). it can.
Next, the cap 6d as the fourth embodiment will be described with reference to FIGS.
Here, the cap 6d is different from the first to third embodiments in that the support member provided on the right cover 4 (exterior portion) and the operation force receiving portion are integrated, and are integrally connected to the front side of the pair of pieces. However, since the other configurations such as the assembly configuration are the same, a duplicate description is omitted.
Here, polypropylene (PP) resin is adopted as the molding material of the main body 13, and a high-rigidity dissimilar material (for example, an ABS material containing glass) is adopted as the molding material of the support member to perform two-body molding. I will do it. The common operation force receiving portion 25 is formed by bending a thin long plate piece and integrally connecting both side ends thereof to the pair of piece portions 16a and 16b so as to bridge the bent portion 15. Further, a notch hole 26 is formed in the middle bent portion 15 of the pair of piece portions 16 a and 16 b and the upper and lower vicinity portions thereof and opposed to the common operation force receiving portion 25.

Such a shared operation force receiving portion 25 is highly rigid, and the pair of pieces 16a and 16b, which are functions of the support member, bend in a free state with a surface side smaller than 180 ° as shown in FIG. Can be held. Further, the common operation force receiving portion 25 is formed so that the left and right side edges along the longitudinal direction form a knob-shaped portion in addition to the support member. For this reason, the shared operation force receiving portion 25 can perform both the function of the support member and the function of the knob-shaped portion, thereby simplifying the configuration by sharing. In addition, there is no member protruding to the back side from the point of being integrally coupled to the front side of the pair of pieces.
Thus, since the common operating force receiving portion 25 is integrally coupled to the front side of the main body 13, the pair of pieces 16a, 16b can be bent and deformed by the middle folding portion 15 by receiving this operating force, Thereby, a nail | claw part can be removed from exterior goods and a cap can be removed. Thus, the left and right side edges of the shared operating force receiving portion 25 that is also a support member form a knob-shaped portion, and by pinching the both side edges from the direction of arrow c (see FIG. 11A) by hand, The cap (3e) can be easily removed.

Furthermore, by changing the formation position of the support member as shown in Embodiment 1 from the back surface of the cap 6d to the front surface, a space is created on the cap back surface portion, and the space portion can be used effectively.
Further, the common operating force receiving portion 25 having the function of a support member is provided with a notch 26 on the opposite side of the main body 13 side. Thereby, the structure of the metal mold | die used at the time of cap production can be made into the up-down direction opening (structure of only a cavity and a core), and prevention of complication of a metal mold | die structure and reduction of metal mold production cost can be aimed at. In the cap 6a according to the first embodiment or the like, the support member 14 provided on the back side of the main body 13 overlaps in the mold opening direction, and the mold configuration requires a slide core configuration in addition to the vertical opening. The complexity of the mold and the cost of mold production were increasing. From this point, the cap 6d of Embodiment 4 can contribute to cost reduction.
