There were problems such as making the design difficult.

  Therefore, a handle that is always stored and pulled out during transportation, such as a shrine-type handle or a pipe-type handle, was more preferable from the viewpoint of ease of holding. However, such a handle has problems such as forgetting to return to the retracted state after use, and injuries by hooking a part of the body to the handle, or by hooking and tearing clothes.

  For this reason, some conventional handles of this type are provided with a return spring or the like so that when the hand is released from the handle, the handle returns to its original position. However, since such a handle requires a separate return spring or the like, there is a problem that the number of parts is increased and the cost is increased.

  For this reason, in some conventional handles, the shaft is supported by the structure of the device, and the lever handle for transporting the device around the shaft is placed in a vertically retracted state and resists gravity from that state. There are some that can be swung freely between the horizontal use state where the tip is pulled out. During transportation, the front end is pulled out against gravity, and when the hand is released from the handle after transportation, the handle is returned to its original vertical retracted state by gravity. In such a lever handle holding device, since it is not pushed deeply into the device main body when stored, it can be provided relatively easily by placing it along the surface of the exterior cover even in a place where there is no room in the device main body. It was.

  A transport lever handle 118 is attached to the first reinforcing bracket 67 via a shaft 78. The lever handle 118 includes a steel plate main body member 81 and a resin cover member 82. The main body member 81 is formed in a U-shaped cross section using, for example, a high-tensile steel plate and the like, and an open portion is used upward, and a shaft hole 83 is opened at the proximal end. The cover member 82 is similarly formed in a U-shaped cross section, and is integrated with the assembly screw 84 by covering the main body member 81 with the open portion facing downward. The lever handle 118 formed by assembling the main body member 81 and the cover member 82 has a lever shape as a whole, and when the lever handle 118 is held, the position of the main body member 81 of the lever handle 118 in a wave shape is formed. Formed.

  The shaft 78 has a head 85 with an enlarged diameter at the proximal end, and a circumferential groove 86 is provided on the outer periphery of the distal end. Then, after inserting the tip into one shaft hole 71 of the first reinforcing bracket 67, it passes through both shaft holes 83 of the lever handle 118, and then passes through the other shaft hole 71 of the first reinforcing bracket 67. 6 through the shaft escape hole 64 of the bent piece 63, put into the shaft hole 76 of the second reinforcing bracket 75, and hit the head 85 against the outer surface of the outer opposing plate 70, and the state shown in FIG. To do.

  Thereafter, a shaft presser 88 made of a high-strength steel plate or the like is attached to the second reinforcing bracket 75 from above and fixed with an assembly screw 89. A part of the shaft presser 88 is put into the circumferential groove 86 and the shaft 78 shaft is fixed. Regulate direction movement.

  Accordingly, the first reinforcing bracket 67 is attached to the front side plate 61 constituting the structure 60 by the lever handle holding device 62, and the shaft 78 is supported by the first reinforcing bracket 67 and the front side plate 61. The lever handle 118 for transportation around the 78 is swingable between a vertically retracted state in which the tip is hung downward and a horizontal use state in which the tip is pulled out against the gravity from the state. Hold.

  In a normal state, the lever handle 118 hangs downward at the tip and is housed in the copying machine main body 10 as shown in FIG. At this time, since the lever handle 118 has the cover member 82 on the outside, the cover member 82 has the same appearance as the exterior cover of the copying machine main body 10 or the same material, so that the appearance can be improved in terms of shape and material. Integrate and cover the functional main body member 81 so as not to feel uncomfortable. Further, it is preferable that the tip of the lever handle 118 is slightly protruded from the exterior cover so that the presence of the lever handle 118 can be easily recognized when viewed from the front, and the finger can be easily put on the tip.

  When moving the copying machine main body 10, put the finger on the tip of the lever handle 118, pull it forward, lift it with the tip, swing around the shaft 78, and swing the lever handle 118 before long. 7 and 8, the base end is brought into contact with the abutting portion 90 of the first reinforcing bracket 67, and the lever handle 118 is leveled as shown in FIGS. Then, the copying machine main body 10 is moved by placing the hand on the lever handle 118 and another digging type handle 116. Thereby, the lever handle 118 can be firmly held without receiving a load from the strong first reinforcing bracket 67 and causing the structure 60 to be distorted. Further, the second reinforcing bracket 75 can restrict the movement of the shaft 78 in the direction orthogonal to the axial direction.

  At this time, the load applied in the swinging direction of the lever handle 118 can be received by the strong first reinforcing bracket 67 via the shaft 78 and dispersed and acted on the bent piece 63. Further, the load applied in the direction orthogonal to the swinging direction of the lever handle 118 is received by the head 85 of the shaft 78 in addition to the first reinforcing bracket 67 and the second reinforcing bracket 75, and the outer opposing plate portion 70. Can hold open. Further, the axial force applied to the shaft 78 can be pressed by the head 85 and the shaft presser 88, and the tilt of the shaft 78 can be pressed by the first reinforcing bracket 67 and the second reinforcing bracket 75.

  In addition, although the bending piece part 63 was provided in the one side edge of the front side board 61 of the structure 60, of course, the bending piece part 63 may be provided in a both-sides edge, and you may make it attach the lever handle 118 to both sides of a front. However, not only the front plate 61 but also the lever handle 118 may be attached by providing a bent piece portion on one side edge or both side edges of the rear side plate or on one side edge or both side edges of the left and right side plates. . Further, not only the side edge of the side plate, but also a lever handle holding device may be provided by attaching a lever handle to the cut and raised portion of the plate surface in the same manner as described above.

  Although not shown in the drawings, when the exterior cover of the image forming apparatus main body is opened, for example, a stopper member may work to prohibit the lever handle from swinging from the vertical storage state to the horizontal use state. . In this way, when the exterior cover is opened, the center of gravity of the main body of the image forming apparatus moves, and when the weight balance becomes worse when holding the handle, the lever handle is swung from the retracted state to the used state. The image forming apparatus main body can be transported in the most preferable state.

  Now, in the color copying machine as described above, when the lever handle 118 is placed in a horizontal use state, the copying machine main body 10 is moved and then the lever handle 118 is released, the lever handle 118 is released. Automatically returns to the retracted state due to gravity. However, for example, during the assembly process, it may be desired to move several times immediately after the movement. In such a case, it is desirable to hold the lever handle 118 as it is.

  For such a case, when the lever handle 118 is in a horizontal use state as shown in FIGS. 7 and 8, for example, as shown in FIG. 11, between the pair of opposed plate portions 70 of the first reinforcing bracket 67. A holding member 100 to be inserted may be provided. The holding member 100 is provided with a fitting portion 101 that fits between a pair of opposing plate portions 70, a support portion 102 that supports the lever handle 118, and an abutment portion 103 that abuts against the structure 60.

  When the lever handle 118 is to be held in use during the assembly process or the like, as shown in FIG. 12, the holding member 100 is inserted under the lever handle 118 in use and the fitting portion 101 of the holding member 100 is inserted. Is fitted between the pair of opposing plate portions 70 of the first reinforcing bracket 67 so that the abutting portion 103 is abutted against the structure 60, and the lever handle 118 is supported by the support portion 102 to prevent the lever handle 118 from returning. Of course, at this time, the holding member 100 is attached so as not to obstruct the holding of the lever handle 118. Then, when it is possible to complete the operation and return the lever handle 118 to the retracted state, the holding member 100 is pulled out, the fitting portion 101 is removed from between the pair of opposing plate portions 70, and the lever handle 118 is removed. Return to the retracted state due to gravity. By doing in this way, workability | operativity of an assembly worker etc. in the middle of an assembly process etc. can be improved.

  Further, even after the structure 60 is covered with the exterior cover, there is a case where the lever handle 118 is desired to be kept in use, for example, when a service person performs an operation during machine installation or maintenance. Also in such a case, as shown in FIG. 13, the lever handle 118 is similarly used and the holding member 100 is inserted under the lever handle 118 to prevent the lever handle 118 from returning.

  Similarly, the holding member 100 is provided with a fitting portion, a support portion, a bump portion, and the like, and the fitting portion is fitted between the pair of opposed plate portions 70 of the first reinforcing bracket 67 so that the bump portion is the structure 60. The lever handle 118 may be supported by the support portion to prevent the lever handle 118 from returning. When the work of the service person is completed, the holding member 100 is pulled out and the lever handle 118 is returned to the retracted state by gravity. By doing so, it is possible to improve the workability of a service person at the time of machine installation or maintenance.

  At this time, the holding member 100 protrudes and is provided with a cover pressing portion 104, and when the holding member 100 is attached, the cover pressing portion 104 presses, for example, the front cover 105 that is opened when installing the internal device or unit, Unless the holding member 100 is removed, it is preferable that the front cover 105 cannot be opened. In this way, when the service person opens the front cover 105 and performs the final installation work, the holding member 100 is removed, and it is possible to eliminate the forgetting to return the lever handle 118 to the retracted state.

  Although described with the front cover, the cover pressing portion 104 provided on the holding member 100 may be pressed against another cover for performing installation work to prevent the opening.

  The holding member 100 is made of a resin or a softer cushion material, and covers a part of the lever handle 118 or wraps the whole, so that an operator or serviceman can temporarily use the lever. Even if the handle 118 is touched, the risk of injury can be reduced and safety can be further increased.

  By the way, in the case of equipment such as an image forming apparatus that moves by holding the digging type handle provided on the exterior cover when carrying the equipment body, the exterior cover must be attached before attaching the exterior cover during the manufacturing process or during maintenance. When removed, there is no handle and the equipment is inconvenient to carry. There is a risk that the device may be damaged or the device may be dropped due to carelessly trying to move the projection.

FIG. 14 shows a lever handle holding device 62 suitable for use in such a case.
As shown in FIG. 15, the illustrated lever handle holding device 62 is provided with a reinforcing bracket 67, a lever handle 118 including a main body member 81 and a cover member 82, a spring 92, a shaft 78, a shaft presser 93, and the like. Then, with the left outer cover of the copying machine main body 10 not attached as shown in FIG. 15, a lever handle 118 is attached if desired, and the lever handle 118 is raised as shown in the figure to make it in a horizontal use state. The copying machine main body 10 can be transported with a handle 118.

  The reinforcing bracket 67 is formed by bending a plate material into a U-shaped cross section, having shaft holes 71 facing each other on the opposing plate portion 70, and two hooks on the upper side and one hook on the lower side, as in the previous example. A nail 94 is provided. The body member 81 of the lever handle 118 has a shaft hole 83 at the base end, covers the cover member 82, and is integrated with an assembly screw 84.

  The shaft 78 passes from the one side of the reinforcing bracket 67 through the shaft hole 71 of the one opposing plate portion 70, then passes through the shaft hole 83 of the main body member 81, passes through the shaft hole 71 of the other opposing plate portion 70, and has a tip end. It protrudes to the other side of the reinforcing bracket 67. Then, the spring 92 biases the tip in a direction protruding from the other side of the reinforcing bracket 67, and presses the flange portion 95 of the shaft 78 against the plate surface of the one opposing plate portion 70. Then, the shaft retainer 93 is screwed to the reinforcing bracket 67 to hold the shaft 78, thereby preventing the shaft 78 from coming off.

  Then, the reinforcing bracket 67 that supports the lever handle 118 in a swingable manner is attached to the bent piece 63 of the structure 60 as shown in FIGS. The bent piece 63 is provided with a reverse-drum-shaped shaft hole 96 in which large and small holes are connected, and two hook holes 97 provided on the shaft hole 96 and one hook hole 97 provided below the shaft hole 96.

  When the hooking claw 94 is inserted into the hooking hole 97, the tip of the shaft 78 presses against the hole edge of the smaller hole of the shaft hole 96. Therefore, when one opposing plate portion 70 of the reinforcing bracket 67 is overlapped with the bent piece portion 63 while the shaft 78 is pushed back against the spring 92, the state shown in FIGS. Next, when the reinforcing bracket 67 is slid upward from that state and the hooking claw 94 is hooked on the hooking hole 97 as shown in FIGS. 20 and 21, the tip of the shaft 78 moves to the larger hole of the shaft hole 96. Then, the shaft 78 returns by the urging force of the spring 92 and the tip fits into the larger hole, and the reinforcing bracket 67 that supports the lever handle 118 so as to be swingable is completely attached to the structure 60.

  When the copying machine main body 10 is moved, a finger is placed on the tip of the lever handle 118 and pulled forward, lifted by holding the tip, and swung around the shaft 78 to cause the lever handle 118 to swing. Eventually, the base end is brought into contact with the abutting portion of the first reinforcing bracket 67, and the lever handle 118 is leveled as shown in FIGS. Then, the copying machine main body 10 is moved by placing the hand on the lever handle 118 and the other digging type handle 116. Thereby, the lever handle 118 can be firmly held without receiving a load from the strong first reinforcing bracket 67 and causing the structure 60 to be distorted. Further, the second reinforcing bracket 75 can restrict the movement of the shaft 78 in the direction orthogonal to the axial direction.

  After transportation, the shaft 78 is pushed from the inside to move against the spring 92 in the axial direction, disengagement from the shaft hole 96, and then the reinforcing bracket 67 is moved downward to hook the hook hole 97 against the hook hole 97. The latch 94 is removed, and the lever handle 118 is removed so that the lever handle 118 remains attached so as not to get in the way.
