Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 shows a copying machine as an example of an image forming apparatus according to the present invention. In FIG. 1, only a frame of a structure is shown, and internal structures are omitted.

In the copying machine of this embodiment, the apparatus structure is freely divided into two parts vertically, and the reference numeral 1 denotes an upper structure and the reference numeral 2 denotes a lower structure. An exterior cover (not shown) is attached to the illustrated frame of each of the upper and lower structures 1 and 2. Note that the front side (the surface facing the operator) of this device is the side indicated by arrow A.

A pair of positioning pins 5, 5 are implanted at the bottoms of the two lateral frame frames 3, 3 of the upper structure 1 with a space therebetween. The upper structure 1 is positioned with respect to the lower structure 2 when the two structures 1 and 2 are connected by engaging the fitting holes 6 and 6 formed in the two horizontal frame frames 4 and 4. . Note that the load of the upper structure 1 is received by the horizontal frame 4 that the horizontal frame 3 contacts.

After the upper structure 1 is positioned, the two structures are fixed to each other in the following manner, so that separation of the upper and lower structures 1 and 2 and vibration of the upper structure 1 are prevented.

A pair of handle members 9, 9 are attached to the vertical frame 7 of the upper structure 1 at a distance from each other. Note that a pair of exactly the same grip members are also attached to the opposite vertical frame frame, but the description of this side will be omitted.

As shown in FIGS. 2 and 3, each of the handle members 9 has a concave portion 9A into which a finger can be inserted when the upper structure 1 is carried. The handle member 9 configured in this manner is fixed to the vertical frame 7 of the upper structure 1 with screws 11. On the other hand, screw holes 12, 12 (FIG. 1) are drilled in the vertical frame 8 of the lower structure 2,
With the upper structure 1 positioned as described above, the fixing locking screw 13 inserted into the recess 9A is inserted into the screw hole 1.
2, the upper structure 1 is fixedly held to the lower structure 2 so as not to move.

As described above, the fixing and locking screw 13 locks the handle member 9 as a locked member, thereby
This is an example of a locking member that fixes and holds the upper structure 1 so as not to move with respect to the lower structure 2.

According to this embodiment, since the handle member 9 is also used as the member to be locked, a dedicated locking bracket or the like is not required, and the fixed locking screw 13 as the locking member is used for the grip member 9. Is stored in the concave portion 9A, so that the appearance is not impaired. Further, the two structures 1 and 2 can be immediately separated only by removing the fixing locking screw 13 without removing other components such as the exterior cover. Further, the load of the upper structure 1 is received by the horizontal frame 4 itself of the lower structure 2, so that no load is applied to the fixing and locking screw 13 and this screwing and removing can be easily performed. Can be done.

In the embodiment shown in FIG. 4, a cover member 14 for preventing insertion of a finger is attached to the concave recess 19A of the handle member 19, and the cover member 14 is fixed to the lower structure 2 by a fixing / locking screw 13. It stops at the side.

That is, the positioning pin 5 is inserted into the fitting hole 6
After the upper structure 1 is positioned with respect to the lower structure 2, the cover member 14 is inserted into the recess 19A as shown in FIG.
Then, the front end of the cover member 14 is fitted, and the fixing and locking screw 13 is screwed into the screw hole 12 (FIG. 1) of the vertical frame 8. The cover member 14 is fixedly fastened to the vertical frame 8 by screws 13 so that the cover member 14
The grip member 19 to which the is fitted and pressed is held in a fixed state. As a result, the upper structure 1 itself is fixed to the lower structure 2.

If it is assumed that the cover member 14 is not provided, a finger can be inserted into the concave portion 19A of the handle member 19, so that the screw 13 shown in FIG. If a finger is inserted into the concave portion 9A and the upper structure 1 is carelessly lifted, the load of the upper and lower structures 1 and 2 is applied to the handle member 9, so that the handle member 9 is permanently deformed. And may be damaged. The use of the cover member 14 can prevent the handle member 19 from being deformed or damaged. Further, since the opening of the handle member 19 is closed by the cover member 14, the appearance can be further improved. If the cover member 14 is removed, the upper structure 1 can be carried by hanging the handle member 19. At this time, since only the load of the upper structure 1 is applied to the handle member 19, there is no possibility that the handle member 19 is damaged or permanently deformed.

FIG. 5 shows a locking bracket 15 fixed to the side of the lower structure 2 as the locking member, and a retractable slide-type gripping member 29 which engages with the locking bracket 15 and a retractable sliding grip member 29. It was done. The structures 1, 2 and the like are slightly different from those shown in FIG. 1, but the same reference numerals are used for convenience.

A guide member 16 as shown in FIGS. 5 and 6 is fixed to a lower portion of the upper structure 1, and a slide-type handle member 29 is slidably inserted therein. Further, as shown in FIG. 7, a locking bracket 15 is fixed to the vertical frame 8 of the lower structure 2.

When the upper structure 1 is carried, the slide-type handle member 29 is projected outside the structure as shown in FIG. 5, and the projected handle member 29 is grasped by hand. When the upper structure 1 is fixedly connected to the lower structure 2, first, the positioning pin 5 is engaged with the fitting hole 6, the upper structure 1 is placed on the horizontal frame 4, and the handle is traveled. Push the member 29 while sliding it inside.

Then, the handle member 29 is engaged with the locking bracket 15 on the vertical frame 8 of the lower structure 2 as shown in FIG. In this state, the upper structure 1 is fixedly held to the lower structure 2 so as not to move. A stopper pin 17 is attached to the handle member 29, and the stopper pin 17 is hooked on the vertical frame
The handle member 29 protruding to the outside is prevented from coming off.

In this embodiment as well, after the upper structure 1 is fixed, the handle member 29 is stored in the structure, so that the appearance is not impaired and there is no obstruction. Further, in this embodiment, the upper structure 1 can be easily fixed and released without attaching and detaching the fixing / locking screw. That is, there is no need to have a positive will to fasten the upper and lower structures. Furthermore,
Such fixation and release can be performed without attaching or detaching an exterior cover or the like.

FIG. 8 shows a bracket-shaped locking member 20 fixed to the lower structure 2 side as the locking member, and
This is a pivotable handle member 39 that engages with the bracket-shaped locking member 20 during storage.

As shown in FIG. 9, the handle member 39 is pivotally attached to the vertical frame 7 of the upper structure 1 by the pivot 21. The base plate is supported by a support plate 22 fixed to the base plate so as not to be swung up and down. In this state,
The upper structure 1 is carried by holding the protruded handle member 39.

When the upper structure 1 is fixedly connected to the lower structure 2, first, the positioning pins 5 shown in FIG. 8 are engaged with the fitting holes 6, and the upper structure 1 is placed on the horizontal frame 4. In this state, as shown in FIG. 9, the handle member 39 which has traveled is grasped and turned around the pivot 21 in the direction of the arrow, and is stored in the upper structure 1 as shown in FIG. In this state, the hook-like portion 39A on the base end side of the handle member 39 is engaged with the bracket-shaped locking member 20, and by this engagement, the upper structure 1 is fixed so as not to move with respect to the lower structure 2. Will be retained.

Also in this embodiment, since the handle member 39 is stored in the upper structure 1, the appearance of the copying machine is not impaired, and it is not necessary to screw in or remove the fixing / locking screw. Absent. Further, in this embodiment, the handle member 39
Is provided along the side of the upper structure 1, so that the inside of the structure can be widely used in space. Further, the operation resistance when rotating the handle member 39 is only when the hook-shaped portion 39A is engaged with the locking member 20, and otherwise does not require any strong operation force. The fixing of the upper structure 1 to the lower structure 2 and the release thereof can be performed with a relatively small operating force.

The present invention can be widely applied to various image forming apparatuses other than a copying machine.

[0034]

According to the first aspect of the present invention, the upper and lower structures which can be separated from each other can be easily and without deteriorating the appearance without attaching / detaching the outer cover. Can be fixed by bonding. Further, since the handle member is also used as the locked member, a dedicated locking bracket or the like can be omitted. In addition, since the fixing and locking screw is not exposed, the appearance can be further improved. Unless the fixing and locking screw is removed, the upper structure cannot be lifted, so that the handle member is damaged. Or deformation can be prevented. Further, since the recessed portion of the handle member is closed, the appearance can be further improved.
