  Next, a coupling structure used in the above-described image forming apparatus will be described. FIG. 3 is a perspective view showing an example of a coupling structure according to an embodiment of the present invention. The coupling structure 30 includes a stopper 31 (second member) as a rotating body, and a mounted member 32 (first member) to which the stopper 31 is attached. The stopper 31 and the attached member 32 are formed of different materials (resin molding material). In particular, the attached member 32 is made of a flexible resin molding material.

  When the stopper 31 is attached to the attached member 32, a protrusion 33 projecting in a substantially cylindrical shape in an external view for insertion (insertion) into the opening 311 (hole) of the stopper 31 is provided on the attached member 32. The main body 34 is formed integrally with a predetermined box (see FIG. 1) to which the paper feed roller 464 is attached. A part 301 is provided. The snap-fit portion 301 faces the slit 331 formed in the projecting direction of the projecting portion 33, and the stopper 31 escapes when the projecting portion 33 is fitted into the opening 311 of the stopper 31. Two columnar bodies 302 having a retaining portion 3011 for preventing them on the outer peripheral surface side and having flexibility (can be bent with elasticity), and integrally formed at the tip of each columnar body 302 In order to bend each of the columnar bodies 302 toward the slit 331 side, there are provided two gripping portions 303 for gripping (holding) with a finger or a tool such as pliers or pliers.

  The two gripping portions 303 are each formed with a notch portion 304 that is notched on one side with respect to the protruding direction. However, the notch 304 includes a case where one side with respect to the protruding direction is notched from the base end (base; the tip position of each columnar body 302) of the gripping portion 303 to the tip. Hereinafter, a portion of each gripper 303 that is not the notch 304 is referred to as a non-notch 305.

  Here, FIG. 5 shows a schematic view when the protrusion 33 is viewed from the front direction, that is, from the direction indicated by the arrow B in FIG. As shown in FIG. 5, the notch 304 in the gripping part 303 is opposed to the notch 304 of one gripping part 303 and the non-notch part 305 of the other gripping part 303 with the slit 331 interposed therebetween. (Each notch 304 (non-notch 305) is formed at a point-symmetrical position across the slit 331 in the gripper 303). When a force is applied to the gripping portion 303 from both sides, that is, from the direction indicated by the arrow C, the columnar body 302 in which the gripping portions 303 are integrally formed bends toward the slit 331 (the gripping portion 303). 2), the notch 304 in one gripping part 303 is inserted into the position of the non-notch 305 in the other gripping part 303, and the two grips are held. The parts 303 are in a state of intersecting with each other, and thus interference between the gripping parts 303 is avoided.

  FIG. 6 is a schematic view showing a state in which the gripping portions 303 intersect each other when the snap fit portion 301 is viewed from the arrow direction indicated by the symbol D in FIG. However, the illustration of the retaining portion 3011 in the columnar portion 302 is omitted, and the reference numeral 601 in the drawing indicates the snap fit portion 301 in a state before bending, and the reference numeral 602 indicates a snap in a bent state. The fitting part 301 is shown.

  As shown in the figure, the amount of displacement of the snap fit portion 301 when the notched portion 304 and the non-notched portion 305 of each gripping portion 303 are bent in a state where they intersect with each other, that is, The stroke 603 shown in FIG. 6 becomes larger than the stroke 902 in the bent state shown in FIG. When the stopper 31 attached to the attached member 32 is removed, that is, when the stopper 31 is removed from the projection 33, the stroke 603 when the snap fit portion 301 is bent increases. It is possible to easily remove the retaining portion 301 that is hooked to the peripheral portion of the portion 311 from the peripheral portion.

Each columnar body 302 has a side surface portion (a portion indicated by reference numeral 306 shown in FIGS. 3 and 5) on the opposite side to the slit 331 in the columnar body 302 when the protrusion 33 is viewed in the arrow direction indicated by the reference numeral B. A flat portion is formed so as to be a so-called “string” in which the circular shape of the case is cut out. Thereby, the columnar body 302 becomes substantially plate-shaped (prism-shaped), and the snap fit portion 301 is easily bent. Further, reference numeral 307 in FIG. 3 indicates a seat (seat 307) formed integrally with the projection 33 and the main body 34 with respect to the stopper 31 fitted into the projection 33. Further, the portion of the protrusion 33 in the range indicated by reference numeral 309 is the bottom 3 of the slit 331.
A portion between 08 and the seat portion 307 is a support portion (support portion 309) for supporting the stopper 31 together with the snap fit portion 301.

The stopper 31 includes a cylindrical body 312 having the opening 311 (the opening 311 corresponds to the inside of the cylindrical body of the cylindrical body 312) and an arm portion 313 that is substantially L-shaped (reverse L-shaped) in external view. Is formed. As shown in FIG. 4, the stopper 31 is attached to the attachment member 32 in a state where the snap fit portion 301 (projection portion 33) is inserted into the opening 311.
When inserting, the stopper 31 (the cylindrical body 312) is pushed to the position of the columnar body 302 by passing the retaining portion 3011 through the opening 311 while bending the snap fit portion 301.

  The stopper 31 is loosely fitted to the protrusion 33, and the recording paper inserted from the direction indicated by the arrow T is brought into contact with the side surface portion 3131 of the arm portion 313 to temporarily feed the recording paper. It functions as a so-called paper stopper that stops. When the recording paper is fed, the stopper 31 rotates in the direction indicated by the arrow E, and the conveyance path in the direction indicated by the arrow T is opened. In this case, the abutting portion 3132 projecting from the upper portion of the stopper 31 abuts on, for example, the rotation stop plate 341 projecting from the main body portion 34 to stop the rotation of the stopper 31. However, a support body (not shown) is provided on the main body portion 34 at the position of the corner portion 342 of the arm portion 313 so that the arm portion 313 does not rotate in the direction opposite to the arrow direction indicated by the symbol E. It has become.

  As shown in FIG. 3, the retaining portion 3011 has a so-called chamfered shape so that it has a mountain shape (or an umbrella shape) toward the gripping portion 303, and the stopper 31 has a chamfered shape. By pushing the cylindrical body 312 (peripheral edge of the opening 311) while abutting, the snap fit portion 301 can be bent without gripping the grip portion 303 from both sides.

  Note that the above-described coupling structure is not limited to a portion provided with the stopper 31 of the manual sheet feeding unit, but a rotating member such as a gear or a pulley or a rotating member in the copying machine 1, for example, a certain member. The present invention is also applied to a connecting structure of a part that is attached to the other member.

  As described above, according to the coupling structure 30 of the present invention, the projecting portion 33 of the attached member 32 faces with the slit 331 formed in the projecting direction of the projecting portion 33 sandwiched between the projecting portion 33 and the stopper 31. Two columnar bodies 302 having flexibility provided with retaining portions 3011 for retaining when fitted in the openings 311 on the outer peripheral surface side, and integrally formed at the tips of the respective columnar bodies 302, The columnar body 302 includes a gripping portion 303 for holding the columnar body 302 to bend toward the slit 331, and a notch 304 is formed in each gripping portion 303, and the notch 304 includes each columnar body 302. Is a notch that allows interference between the gripping portions 303 and allows the gripping portions 303 to cross each other when bent toward the slit 331 side.

As described above, when the columnar bodies 302 are bent by providing the gripping portions 303, the retaining portions 301 are provided.
1 can be easily grasped (pick), and the columnar body 302 (snap fit portion 301) can be bent with a smaller force by a finger or the like without using a special tool. In addition, the grip portions 303 do not interfere with each other, that is, the notch portion 304 in one grip portion 303 is inserted into the position of the non-notch portion 305 in the other grip portion 303 so that the grip portions 303 intersect each other. Since each columnar body 302 can be bent until it becomes a state where the protrusions 33 of the attached member 32 are fitted into the openings 311 of the stoppers 31, the retaining portions 3011 are connected to the edges of the openings 311. It is easy to remove the stopper 31 (attached member 32) from the attached member 32 (stopper 31) by removing it from the (peripheral portion), and thus an apparatus (for example, a copy) having a coupling structure consisting of the stopper 31 and the attached member 32. The resolvability of the image forming apparatus such as a printer can be improved.

  In particular, the material of the stopper 31 is, for example, POM (Polyoxymethylene) resin, and the material of the mounted member 32 is, for example, ABS (Acrylonitrile Butadiene Styrene) resin, and thus includes the copying machine 1 (image forming apparatus). When each member of the attachment side and the attachment side (here, the stopper 31 and the attached member 32) of the coupling structure provided (assembled) in various devices such as electrical / mechanical devices are made of different materials ( In this case, there is a high demand for separating both at the time of recycling). However, by using the joint structure of the present invention, the decomposability of the various devices is improved, and damage due to breakage of each member occurs at the time of disassembly. It is possible to prevent different parts from being mixed, and to separate and recycle each material (separate recycling). There are can increase the value of recycling materials (value added).

  In addition, each gripping portion 303 has a notch portion 304 in one gripping portion 303 and a non-notch portion 305 in the other gripping portion 303 at positions where the notch portions 305 face each other with the slit 331 interposed therebetween. A notch 304 is formed by notching one side with respect to the protrusion direction. Thereby, when the columnar body 302 is bent, the structure for intersecting the gripping portion 303 can be simplified.

  In addition, this invention can take the following aspects.

(A) In the present embodiment, each gripping portion 303 has 1 for each gripping portion 303 as shown in FIG.
One notch 304 (non-notch 305) is formed. For example, as shown in FIG. 7, the notch 701 (not centered in the center) is formed at both ends in the slit direction indicated by reference numeral 705 in one gripping part 710. A notch 703) may be formed, and a notch 702 (a notch 704 at both ends) may be formed at the center of the other gripping portion 720 in the slit direction. Further, the arrangement is not limited to this, and one or the other gripping portion is formed with three or more notches (or non-notches), and the notches and the notches are opposed to each other across the slit. (For example, staggered arrangement) may be used. In any case, when the snap fit portion 301 is bent, interference between the gripping portions 303 is avoided, and a notch portion is formed so that the gripping portions 303 cross each other. That's fine.

  (B) In the present embodiment, as shown in FIG. 5, the notch 304 (non-notch 305) in each gripping part 303 is formed in the same size (the length of each side is the same). For example, it may be formed in a shape that is not bilaterally symmetric (not point-symmetric) across the slit 331. In this case, the length of each gripping portion 303 in the protruding direction may be different.

  (C) As shown in FIG. 5, the protrusion 33 (the columnar body 302) does not have to have a substantially circular shape (perfect circle shape) when viewed from the front, for example, an elliptical shape, a square shape, or a rectangular shape. Such a square shape may be used. However, the shape of the opening of the member attached to the protrusion 33 is a shape that matches the elliptical shape or the square shape.
