  The fixing member is a bolt-shaped member in which a screw is formed, and is screwed into a screw hole formed in the lower surface of the apparatus main body. By adjusting the screwing length of the fixing member, the fixing member can be stretched between the lower surface and the floor surface of the apparatus main body to stably support the apparatus main body.

  It is preferable that such a fixing member is screwed in as deeply as possible when the image forming apparatus is transported and retracted from the floor surface because it does not interfere with the floor surface. When installing the image forming apparatus at a predetermined position, the image forming apparatus is installed immovably by extending the fixing member and stretching it with an appropriate force between the lower surface of the apparatus main body and the floor surface.

  Here, when the fixing member is screwed deeply at the time of transportation, a tool is required when the fixing member is drawn out at the time of installation, and there is a problem that the installation takes time. Further, when the screwing length is shortened, there is a possibility that the fixing member is rotated and loosened due to vibration or the like during transportation, resulting in damage.

  Patent Document 3 describes a support mechanism that supports an apparatus main body on a floor surface. The support mechanism includes a fixing member that is screwed from below into a bracket that is fixed to the lower surface of the apparatus main body. When the fixing member is screwed deeply into the bracket, the protrusion formed on the fixing member fits into the locking hole formed on the bracket, so that the rotation of the fixing member is restricted. Yes.

  Hereinafter, a support mechanism 5 and an image forming apparatus 1 according to an embodiment of the present disclosure will be described with reference to the drawings.

  First, the image forming apparatus 1 will be described with reference to FIG. FIG. 1 is a front view schematically showing the image forming apparatus 1.

  The image forming apparatus 1 includes an apparatus main body 4 including an original reading unit 3 and an image forming unit 2, and a support mechanism 5 that supports the apparatus main body 4 on a floor surface F. The document reading unit 3 reads an image from the conveyed document, and the image forming unit 2 forms an image on a sheet based on the image read by the document reading unit 3.

  Next, the support mechanism 5 according to the first embodiment will be described. The support mechanism 5 includes a caster 6 and a fixing member 7, and is provided adjacent to each of the four corners of the lower surface of the bottom plate 4 a of the apparatus body 4. The caster 6 supports the apparatus main body 4 so as to be movable on the floor surface F, and the fixing member 7 prevents the apparatus main body 4 from moving from a predetermined position on the floor surface F. Here, the bottom plate 4a of the apparatus body 4 includes a bracket 8 fixed to the lower surface of the bottom plate 4a.

  Next, the fixing member 7 will be described with reference to FIGS. 2 is a perspective view showing the fixing member 7, FIG. 3 is a cross-sectional view showing the fixing member 7 when the image forming apparatus 1 is installed, and FIG. 4 is a cross-sectional view showing the fixing member 7 when the image forming apparatus 1 is transported. .

  The fixing member 7 can be screwed into the bracket 8 fixed to the lower surface of the bottom plate 4a of the apparatus body 4 from below.

  First, the bracket 8 will be described. As shown in FIG. 2, the bracket 8 includes a rectangular bottom plate 8 a and side plates 8 b that rise from the four sides of the bottom plate 8 a, and are formed of, for example, a sheet metal material. The bracket 8 has a height that is lower than the protruding length of the caster 6 from the lower surface of the bottom plate 4 a of the apparatus body 4. As shown in FIGS. 3 and 4, a cylindrical portion 10 rising from the periphery of the circular opening is formed at the center of the bottom plate 8 a. The cylinder portion 10 has a screw hole 11 in which an internal thread is cut on the inner peripheral surface.

  The upper ends 8c of the pair of opposing side plates 8b are bent at right angles in opposite directions. A screw fixing through hole 13 and a positioning through hole 14 are formed in each upper end portion 8c. A screw hole corresponding to the screw fixing through hole 13 and a positioning projection corresponding to the positioning through hole 14 are formed on the lower surface of the bottom plate 4a of the apparatus body 4 (both not shown). Each positioning projection is fitted into each positioning through hole 14 and screwed into each screw hole through each screw fixing through hole 13 through screws B (see FIGS. 5 and 6), whereby the bracket 8 is attached to the bottom plate 4a of the apparatus main body 4. It is fixed to the lower surface of the.

  Next, the fixing member 7 will be described. As shown in FIG. 3, the fixing member 7 includes a shaft portion 20 and a leg seat 21 provided at the lower end of the shaft portion 20 and having a diameter larger than that of the shaft portion 20. The shaft portion 20 is a bolt-shaped member, and includes a screw portion 23 formed with a male screw that meshes with the screw hole 11 of the bracket 8, and a head portion 24 provided at the lower end of the screw portion 23. The length of the screw part 23 is longer than the height of the bracket 8. A groove portion 26 in which no male screw is formed is formed at the lower end portion of the screw portion 23. That is, the outer diameter D1 of the groove portion 26 is smaller than the outer diameter of the screw portion 23 (male screw) and smaller than the inner diameter D2 of the screw hole 11 (female screw). Furthermore, the length H1 of the groove part 26 in the length direction of the shaft part 20 is longer than the length H2 of the screw hole 11 (cylinder part 10). As an example, the difference between the length H1 of the groove portion 26 and the length H2 of the screw hole 11 is 1.5 mm (when an M8 screw (screw pitch 1.25 mm) is used as the shaft portion 20). At the center of the lower surface of the head portion 24, an engagement groove 24a that can be engaged with a driver is formed.

  The leg seat 21 is a disk-shaped member having a larger diameter than the head portion 24 and can contact the floor surface F. A through hole 31 is formed in the center of the leg seat 21. In the vicinity of the center of the through hole 31 in the height direction, a cutout hole 33 that extends from the through hole 31 in the radial direction is formed. The cutout hole 33 accommodates the head portion 24 of the fixing member 7. The leg seat 21 is formed of an elastic material such as rubber.

  The fixing member 7 is assembled to the bracket 8 by screwing the screw portion 23 of the shaft portion 20 into the screw hole 11 of the cylindrical portion 10 from below.

  The operation of the support mechanism 5 according to the first embodiment during transportation and installation of the image forming apparatus 1 will be described with reference to FIGS. 5 and 6. 5 is a front view showing the support mechanism 5 when the image forming apparatus 1 is transported. FIG. 6 is a front view showing the support mechanism 5 when the image forming apparatus 1 is installed.

  As shown in FIG. 5, when the image forming apparatus 1 is transported or transported, the fixing length of the fixing member 7 from the bottom surface of the bottom plate 4 a of the apparatus body 4 is fixed so as to be shorter than the protruding length of the caster 6. The member 7 is retracted. That is, the screw portion 23 of the fixing member 7 is screwed into the screw hole 11 of the bracket 8. At this time, if there is a space below the image forming apparatus 1, a tool such as a screwdriver is engaged with the engagement groove 24 a of the shaft 60 of the fixing member 7 and screwed using this tool.

  When the screw portion 23 is screwed into the screw hole 11, the protruding length of the fixing member 7 gradually decreases, and the leg seat 21 rises above the lower surface of the caster 6. When the screw portion 23 is screwed until the groove portion 26 is finally passed through the screw hole 11, the outer diameter D1 of the groove portion 26 is smaller than the inner diameter D2 of the screw hole 11, so that the groove portion 26 and the screw hole 11 cannot be screwed together. The fixing member 7 is idled with respect to the bracket 8. When the screwing force is released in this state, as shown in FIG. 4, the fixing member 7 locks the male screw of the screw portion 23 to the upper end surface of the cylindrical portion 10 by its own weight. At this time, since the length H1 of the groove 26 is longer than the length H2 of the screw hole 11, a slight gap g is formed between the lower surface of the bottom plate 8a of the bracket 8 and the upper surface of the leg seat 21. When the screw portion 23 is screwed into the screw hole 11, the tip of the screw portion 23 protrudes through the through hole 1 a formed in the bottom plate 4 a of the apparatus body 4.

  Thus, after the leg seat 21 is retracted above the lower surface of the caster 6 and the fixing member 7 is screwed into the bracket 8 until the groove portion 26 reaches the screw hole 11, the image forming apparatus 1 is transported, or The apparatus body 4 is moved on the floor surface F to a predetermined position by the caster 6.

  When the apparatus main body 4 is installed at a predetermined position, the shaft portion 20 is rotated in the direction opposite to the screwing direction while holding the leg seat 21 and pulling it downward. Then, the screw part 23 comes to mesh with the screw hole 11 in the end, and the fixing member 7 is drawn out from the bracket 8. At this time, since the screw portion 23 is not tightened into the screw hole 11, the fixing member 7 can be fed out without using a tool. And as FIG. 6 shows, the lower surface of the leg seat 21 contacts the floor surface F. As shown in FIG. Accordingly, the fixing member 7 is stretched between the bracket 8 and the floor surface F, and the image forming apparatus 1 is prevented from moving from a predetermined position.

  As described above, in the support mechanism 5 according to the first implementation mechanism, when the image forming apparatus 1 is transported, the fixing member 7 is not screwed to the bracket 8 by the screw portion 23 but can be idled by the groove portion 26. It is kept simple. Therefore, even if vibration or the like is applied during transportation, the fixing member 7 only idles with respect to the bracket 8 and does not rotate with respect to the screw hole 11, so that the fixing member 7 can be reliably retracted. Further, when the apparatus main body 4 is moved on the floor surface F by the casters 6, the leg seats 21 are retracted above the floor surface F, so that they do not interfere with the floor surface F. Can be moved smoothly. On the other hand, when the image forming apparatus 1 is installed, the movement of the image forming apparatus 1 can be prevented by extending the fixing member 7 and bringing it into contact with the floor surface F, as in a general configuration. In this way, the fixing member 7 can be screwed in and retracted by a simple method, and the distance from the bottom plate 4a of the apparatus body 4 to the leg seat 21 can be adjusted. The convenience of installation work is improved.

  Furthermore, since it is a simple structure which does not form a male screw in a part of screw part 23 of the fixing member 7, it can form in low cost.

  In addition, when the leg seat 21 is formed of rubber, the leg seat 21 and the bracket 8 may be fused if the fixing member 7 is screwed and left without being retracted. However, in the fixing member 7 of the present invention, the length H1 of the groove portion 26 is longer than the length H2 of the screw hole 11, and a gap g is opened between the lower surface of the bottom plate 6a of the bracket 8 and the upper surface of the leg seat 21. Therefore, such fusion can be prevented. Furthermore, if the groove part 26 can be visually recognized from the gap g, a clue that the shaft part 20 may be rotated in order to extend the fixing member 7 can be given.

  Moreover, in this embodiment, since the groove part 26 was formed in the lower end part of the screw part 23, the axial part 20 can be hold | maintained at the bracket 8 in the state which retracted the leg seat 21 to the uppermost part. Therefore, when the image forming apparatus 1 is moved by the caster 6, interference between the leg seat 21 and the floor surface F can be avoided. However, the groove part 26 may be formed in the middle part of the screw part 23.

  Further, in the present embodiment, an example in which the screw hole 11 into which the shaft portion 20 of the fixing member 7 is screwed is formed in the bracket 8 fixed to the lower surface of the bottom plate 4a of the apparatus main body 4 is described. You may form a screw hole directly in the baseplate 4a. However, if the screw hole 11 is formed in the bracket 8, the length of the shaft portion 20 of the fixing member 7 can be shortened by the height of the bracket 8.

  Next, the support mechanism 5 according to the second embodiment will be described with reference to FIGS. 7 and 8. FIG. 7 is a perspective view showing the leg seat 21 of the fixing member 7, and FIG. 8 is a bottom view showing the bracket 8. In the following description, parts / parts having the same configuration as the support mechanism 5 according to the first embodiment are denoted by the same reference numerals as those of the first embodiment, and the description thereof is omitted.

  As shown in FIG. 7, on the upper surface of the leg seat 21, two convex portions 41 are formed as engaging portions at positions that are point-symmetric about the shaft portion 20. Each convex portion 41 has a base portion 51 protruding from the upper surface of the leg seat 21 and a head portion 53 formed at the upper end of the base portion 51. The diameter of the head 53 is larger than the diameter of the base 51. The base 51 has a root portion 51 a that gradually decreases in diameter from the upper surface of the leg seat 21. The length of the base 51 above the base 51a is substantially the same as the thickness of the bottom plate 8a of the bracket 8.

  As shown in FIG. 8, the bottom plate 8a of the bracket 8 is formed with a hole 43 as an engaged portion to which the two convex portions 41 can be engaged. Each hole 43 includes a large-diameter portion 57 having a larger diameter than the head 53 of the convex portion 41 and a small-diameter portion 59 having a diameter smaller than the diameter of the head 53 and larger than the diameter of the base 51. Yes. The large diameter portion 57 and the small diameter portion 59 are continuously formed along the circumferential direction with the screw hole 11 as the center. A narrow portion 61 narrower than the diameter of the small diameter portion 59 is formed between the large diameter portion 57 and the small diameter portion 59.

  Next, the engagement between the convex portion 41 and the hole portion 43 will be described with reference to FIGS. 9 is a cross-sectional view showing a state where the convex portion 41 is not engaged with the hole portion 43, FIG. 10 is a cross-sectional view showing a state where the convex portion 41 and the hole portion 43 are engaged, and FIG. It is sectional drawing which shows the state extracted from the part 43. FIG.

  As shown in FIG. 9, in a state where the screw portion 23 of the shaft portion 20 of the fixing member 7 is screwed into the screw hole 11 of the bracket 8, the convex portion 41 is not engaged with the hole portion 43.

  When the screw portion 23 is screwed in until the groove portion 26 passes through the screw hole 11, the fixing member 7 idles with respect to the bracket 8 and can freely move in the vertical direction. Therefore, the fixing member 7 is rotated about the shaft portion 20 so that the two convex portions 41 are positioned in the large diameter portions 57 of the two hole portions 43 of the bracket 8, and the fixing member 7 is moved upward to increase the size of each large portion. Each head 53 is inserted into the diameter portion 57. The head 53 passes through the large-diameter portion 57 and protrudes above the bottom plate 8 a of the bracket 8, and the base 51 is fitted into the large-diameter portion 57.

  Thereafter, when the fixing member 7 is rotated around the shaft portion 20, the base portion 51 passes through the narrow portion 61 and enters the small diameter portion 59 while being elastically deformed as shown in FIG. 10. When the base 51 enters the small diameter portion 59, the diameter of the head 53 is larger than the diameter of the small diameter portion 59. That is, the fixing member 7 is prevented from coming off from the bracket 8. Furthermore, since the length of the base 51 above the base 51a is substantially equal to the thickness of the bottom plate 8a of the bracket 8, the bottom plate 8a is sandwiched between the head 53 and the base 51a, and the bracket of the fixing member 7 is inserted. The vertical movement with respect to 8 is restricted. At the same time, when the base 51 enters the small diameter part 59, the free movement of the base 51 from the small diameter part 59 to the large diameter part 57 is restricted by the narrow part 61, and the rotation of the fixing member 7 is also restricted. Further, a gap having a height of the base portion 51 a of the base portion 51 is opened between the lower surface of the bottom plate 8 a of the bracket 8 and the upper surface of the leg seat 21.

  Further, in a state where the convex portion 41 is engaged with the hole portion 43 (see FIG. 10), the length A of the groove portion 26 above the screw hole 11 and the convex portion 41 above the lower surface of the bottom plate 8 a of the bracket 8. Is equal to the length B.

  In this state, the image forming apparatus 1 can be transported, or the apparatus body 4 can be moved on the floor surface F to a predetermined position by the casters 6.

  When the apparatus main body 4 is installed at a predetermined position, the fixing member 7 is rotated in the direction opposite to the above. At this time, the base 51 passes through the narrow portion 61 while being elastically deformed. After the fixing member 7 is rotated until the base 51 reaches the large diameter portion 57 and then the fixing member 7 is moved downward, the head 53 of each convex portion 41 is extracted downward from the large diameter portion 57 and screwed. The male screw of the portion 23 is locked to the upper end surface of the cylindrical portion 10. Further, in the engaged state of FIG. 10, the length A of the groove 26 above the screw hole 11 is equal to the length B of the convex portion 41 above the lower surface of the bottom plate 8 a of the bracket 8. As shown in FIG. 4, the height of the upper surface of the convex portion 41 is equal to the height of the lower surface of the bottom plate 8a of the bracket 8.

  Thereafter, when the fixing member 7 is further rotated, the upper surface of the convex portion 41 is rubbed against the lower surface of the bottom plate 8 a of the bracket 8. Eventually, the screw portion 23 engages with the screw hole 11, and the fixing member 7 is fed out from the bracket 8. By extending the fixing member 7 from the bracket 8 until the lower surface of the leg seat 21 contacts the floor surface F, the fixing member 7 is stretched between the bracket 8 and the floor surface F, and the image forming apparatus 1 is in a predetermined position. Movement from is prevented.

  As described above, in the support mechanism 5 according to the second embodiment, the convex portion 41 engages with the hole portion 43 in a state where the fixing member 7 is retracted above the caster 6. The vertical movement and rotation with respect to the bracket 8 are restricted. Therefore, rattling of the fixing member 7 during transportation can be suppressed.

  Further, since a gap is opened between the lower surface of the bottom plate 8a of the bracket 8 and the upper surface of the leg seat 21, the leg seat 21 and the bracket 8 can be prevented from sticking together.

  Furthermore, when the fixing member 7 is extended from the bracket 8, the fixing member 7 may be rotated while sliding the upper surface of the convex portion 41 against the lower surface of the bottom plate 8 a of the bracket 8. Thereby, since the screw part 23 rotates in a perpendicular | vertical attitude | position with respect to the baseplate 8a, the screw part 23 can be meshed | engaged with the screw hole 11 smoothly. Therefore, rattling and vibration of the fixing member 7 during feeding can be eliminated, and the fixing member 7 can be stably fed out from the bracket 8.

  Further, the fixing member 7 is rotated after the head portion 53 of the convex portion 41 is inserted into the large diameter portion 57 of the hole portion 43, so that the head portion 53 is prevented from coming off by the small diameter portion 59. Furthermore, since the free movement of the base 51 from the small diameter part 59 to the large diameter part 57 is restricted by the narrow part 61, the rotation of the fixing member 7 is also restricted. In this manner, the movement and rotation of the fixing member 7 in the vertical direction with respect to the bracket 8 can be restricted with a simple operation.

  Alternatively, the hole 43 is formed to have a diameter smaller than the diameter of the head 53 of the convex portion 41 and larger than the diameter of the base 51, and the convex portion 41 is press-fitted into the hole 43, thereby fixing the fixing member 7. Can also be secured to the bracket 8. Also in this case, the movement and rotation of the fixing member 7 with respect to the bracket 8 in the vertical direction can be restricted by a simple operation of simply pressing the convex portion 41 into the hole portion 43.

  The number of convex portions 41 and hole portions 43 is not limited to two, and may be three or more.

  The fixing member 7 of the present invention can be applied not only to the image forming apparatus 1 but also to a post-processing apparatus attached to the image forming apparatus 1, industrial equipment, home appliances, furniture, and the like.

  The above description of the embodiments of the present invention has described preferred embodiments of the support mechanism and the image forming apparatus according to the present invention, and thus may have various technically preferable limitations. The technical scope of the present invention is not limited to these embodiments unless specifically described to limit the present invention. That is, the above-described components in the embodiment of the present invention can be appropriately replaced with existing components and the like, and various variations including combinations with other existing components are possible.
