TECHNICAL FIELD OF THE INVENTION
The present invention relates to a handle device for carrying equipment and an image forming apparatus provided with the same.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, image forming apparatuses such as a printing apparatus, an image communication apparatus, and a copying machine are relatively heavy devices, and therefore, it has been difficult to transport the image forming apparatuses while climbing stairs. On the other hand, since an office for delivering an image forming apparatus is not always equipped with an elevator, there is a need for a carrier to carry stairs with an image forming apparatus by hand. For this reason, there are devices of this type in which a transport lever is attached to the device body.
[0003]
As such a transport lever, there is a lever provided so as to be able to be pulled out in the horizontal direction of the image forming apparatus (for example, see Patent Document 1). As shown in FIG. 2 of the document, the transport lever is housed inside the device when not transported, and is drawn out of the device when transported and used. In order to prevent the transport lever from returning to the inside of the device during transport, the transport lever is provided with a lock mechanism. By the function of the lock mechanism, the transport lever is maintained in a state of protruding outside the device. When the carrying operation is completed, the lock mechanism is released, and the carrying lever is housed inside the device by the elastic force of the coil spring.
[0004]
Further, as a transport lever, there is a lever provided so as to be rotatable in a vertical direction of the image forming apparatus (for example, see Patent Document 1). As shown in FIG. 7 of the document, the transport lever is housed inside the device when not transported, and is pulled out of the device by being rotated in the vertical direction during transport while being transported. When the transporting operation was completed, the transporting lever was released and dropped by its own weight and stored inside the device.
[0005]
When the image forming apparatus is transported upstairs, two transport levers protrude from the left and right sides of the device, so that two or more transporters are located on the left and right sides of the device, respectively. He held the lever, lifted the entire equipment and climbed the stairs. As shown in FIG. 7 of the document, the transport lever has a generally U-shape that is open upward, so that the force for lifting the transport lever is approximately two U-shaped open ends. Via a vertical plane on the main frame side.
[0006]

[0007]
[Problems to be solved by the invention]
However, such a conventional technique has the following problems.
[0008]
That is, in the case of a configuration in which the transport lever is slid in the horizontal direction to be stored inside the device or taken out of the device,
{Circle around (1)} Since the image forming apparatus has a front opening / closing cover and a paper feed cassette stage, it must be provided at a position where it does not hinder the cover. Therefore, there has been a problem that the mounting position of the transport lever is greatly restricted.
{Circle around (2)} When the transport lever is arranged at a position suitable for transport under the above-mentioned restrictions, the transport lever has to be configured to be thin. In this case, since the weight of the image forming apparatus is heavy, there is a problem in that the carrying lever bites into the hand holding the carrying lever, making it very difficult to carry.
(3) Conversely, if a thick transport lever is provided at a position suitable for transport under the above restrictions, a space for storing the thick transport lever is required, and the entire image forming apparatus must be enlarged. The problem arises.
(4) Since the release mechanism of the lock mechanism can be released with the same hand as the hand holding the transport lever during transport of the image forming apparatus, the hand may erroneously apply force to the angle in the release direction during transport. In addition, a situation occurs in which the lock mechanism is released. Therefore, it is required that the release mechanism of the lock mechanism be a mechanism that is close to the transport lever but is not easily released during transport.
[0009]
If the transport lever is rotated vertically and stored inside or outside the device, hold one end of the transport lever during transport and rotate it vertically. To pull out the device, and then hold the transport lever at one end and use it in a horizontal state.If you stop gripping one end of the transport lever during transport, the transport lever is stored inside the device by its own weight. The problem that it is done occurs.
[0010]
Further, in the above-mentioned conventional technique, the force when lifting the transport lever is directly applied to the vertical surface on the main frame side through the two U-shaped open ends, so that the weight is reduced at the contact point. The transport lever and the main frame are deformed to concentrate on the main frame. In particular, the deformation of the main frame causes inconveniences such as destruction of the mutual relation of the members constituting the recording section and the like, which are maintained with a certain positional accuracy, and lowering the image quality. There was a problem that occurs.
[0011]
The present invention has been made in view of the above-described problems, and is a small and easy-to-hold grip device that is optimal for transporting a device and that can reliably prevent a locked state during transport from being released due to a malfunction.

As described above, in the present image forming apparatus 100, when the upper pivotable handle 102a is fixed in a horizontal state, the upper pivotable handle 102a is pivoted to the horizontal state, and the protrusion 302 is held by the holding section 204 of the storage section 201. Is pulled out horizontally from the image forming apparatus 100 side to a position where the lock member 203 is held, and further, the lock member 203 is moved downward toward the upper surface of the horizontal upwardly-rotating handle 102a to be fitted into the fitting groove 301. The rotation of the upwardly-rotating handle 102a is restricted. For this reason, simply turning the upper-rotating handle 102a to a horizontal state does not lock the lock, and requires two-step operation before the lock is locked. Can be prevented and safe transportation can be guaranteed.
[0132]
Hereinafter, an operation for releasing the locked state of the upwardly-rotating handle 102a fixed in a horizontal state will be described. FIG. 7 is an enlarged view around the fitting groove 301 of the upwardly-rotating handle 102a. FIG. 7 shows a state in which the fitting piece 210 of the lock member 203 has entered the fitting groove 301 of the upwardly-rotating handle 102a.
[0133]
When the fitting piece 210 enters the fitting groove 301, as shown in FIG. 7, the protruding part 302 of the upwardly-rotating handle 102 a is in a state of being placed on the holding part 204. That is, when the fitting piece 210 enters the fitting groove 301 with the protruding portion 302 resting on the holding portion 204, the upwardly-rotating handle 102a is fixed in a horizontal state. At this time, the upper pivotable handle 102a is in a state in which it cannot be pushed into the inside of the storage section 201 nor can it pivot downward.
[0134]
Further, as shown in the figure, the lock release section 304 provided inside the upwardly-rotating handle 102a has an inclined surface 304a that goes down toward the fitting piece 210 of the lock member 203. By forming the inclined surface 304a at the tip of the lock release portion 304, the release of the lock member 203 can be easily and reliably released.
In the state where the fitting piece 210 of the lock member 203 is inserted into the fitting groove 301 of the upwardly-rotatable handle 102a, if no force is applied to the lock release portion 304, the biasing force of the coil spring is used. The inclined surface 304a is disposed slightly outside the apparatus than the fitting piece 210.
[0135]
FIG. 8 shows a state in which the fitting piece 210 of the lock member 203 is pushed upward by the lock release unit 304.
[0136]
When the lock release unit 304 is pushed inward by the carrier from the state shown in FIG. 7, the inclined surface 304a moves toward the fitting piece 210 of the lock member 203, as shown in FIG. The fitting piece 210 of the lock member 203 abutting on the inclined surface 304a moves so as to climb the inclination of the inclined surface 304a. As a result, the fitting piece 210 of the lock member 203 is disengaged from the fitting groove 301 of the upwardly-rotating handle 102a. At this time, the upper pivotable handle 102a is in a state where it can be pushed into the inside of the storage section 201. In this way, the lock of the upwardly-rotating handle 102a fixed in the horizontal state is released.
[0137]
When storing the unlocked upwardly-rotating handle 102a in the storage unit 201, the carrier performs an operation opposite to the operation until the handle is fixed to a horizontal state. That is, after pushing the upwardly-rotating handle 102a to a position where the protruding portion 302 is disengaged from the holding portion 204, the distal end of the upwardly-rotating handle 102a is rotated downward.
[0138]
As described above, in the present image forming apparatus 100, when the upward-rotatable handle 102a is stored in the storage unit 201, the lock release unit 304 is horizontally moved to the lock member 203 side to push the lock member 203 upward, and the fitting is performed. In addition to releasing the engagement with the groove 301, the protrusion 302 is removed from the holding portion 204 by pushing the upwardly-rotatable handle 102a toward the image forming apparatus 100, and the upwardly-rotatable handle 102a is rotated downward. Be movable. For this reason, two steps of operation are required until the upper pivotable handle 102a is pivoted, so that the lock can be locked as compared with the case where the upper pivotable handle 102a is immediately pivoted by releasing the lock member 203. Even if it is released by mistake, the upwardly-rotating handle 102a does not suddenly rotate, and safety can be reliably ensured.
[0139]
Note that, in the present embodiment, a description is given of a case where the upwardly rotating handle 102a is pulled out after being rotated from the image forming apparatus 100 in the process of fixing the upwardly rotating handle 102a in a horizontal state. However, the present invention is not limited to this, and it is also possible to adopt a configuration in which the upwardly-rotating handle 102a is pushed in after being turned in the process of fixing in a horizontal state. Even in such a case, the same effect as that of the present embodiment can be obtained.
[0140]
However, in the case where the upwardly rotating handle 102a is pulled out after being rotated from the image forming apparatus 100 in the process of fixing the upwardly rotating handle 102a in a horizontal state as in the present embodiment, There is no need to push the upwardly-rotating handle 102a into the image forming apparatus 100, and a space for pushing the upwardly-rotating handle 102a into the image forming apparatus 100 is not required, so that the image forming apparatus 100 can be downsized. .
[0141]
Here, the load on the upwardly-rotating handle 102a fixed in a horizontal state will be described. FIG. 9 is a schematic diagram for explaining a load applied to the upwardly-rotating handle 102a fixed in a horizontal state. FIG. 9 illustrates a cross section of the image forming apparatus 100 viewed from the side of the storage unit 201.
[0142]
FIG. 9 shows a state of the upwardly-rotating handle 102a corresponding to FIG. 3 and FIG. That is, a state is shown in which the fitting piece 210 of the lock member 203 enters the fitting groove 301 of the upwardly-rotating handle 102a, and the protrusion 302 of the upwardly-rotating handle 102a is held by the holding section 204 of the storage section 201. ing.
[0143]
As described above, the storage section 201 has a box-like shape, and its inner wall 901 is located inside the apparatus when the upwardly-rotating handle 102a is fixed in a horizontal state as shown in FIG. It is located near the tip. The inner wall 901 has an opening 902 near the tip of the upwardly-rotating handle 102a. The opening 902 is formed to receive the tip of the rotating upper handle 102a inside the apparatus.
[0144]
A first support portion for supporting the vicinity of the tip inside the apparatus of the upwardly-rotating handle 102a on the surface of the inner wall 901 of the storage portion 201 and below the opening 902, that is, at the lower end of the opening 902. 903 are provided. The first support portion 903 is formed by bending the inner wall 901 of the storage portion 201, and has a shape slightly projecting rightward as shown in FIG.
[0145]
On the other hand, the vicinity of the fitting groove 301 of the upwardly-rotating handle 102a is supported at a position facing the first support portion 903 in the storage portion 201, in other words, on the back surface of the storage portion 201 at the position where the lock member 203 is attached. A second support portion 904 is provided. The second support portion 904 is also formed by bending like the first support portion 903, and has a shape slightly projecting toward the inner wall surface 901 of the storage portion 201.
[0146]
When the upper pivotable handle 102a is fixed in a horizontal state, the first support portion 903 and the second support portion 904 receive the load applied to the upper pivotable handle 102a. The load applied to the first support 903 and the second support 904 is transmitted to the main frame of the image forming apparatus 100 via the storage unit 201.
[0147]
As described above, in the image forming apparatus 100, the storage unit 201 includes the upper surface of the upper rotation type handle 102a in the horizontal state in the vicinity of the fitting groove 301 and the upper rotation type handle disposed in the storage unit 201. The force applied to the upwardly-rotating handle 102a is received by the lower surface in the vicinity of the tip of the 102a. Accordingly, the storage unit 201 receives not only an upward force but also a downward force generated when the image forming apparatus 100 is lifted by gripping the upward-rotating handle 102a. For this reason, the storage unit 201 can receive the force generated when the image forming apparatus 100 is lifted up in two directions, up and down. Therefore, the load applied to the storage unit 201 can be reduced as compared with the case where the force is received only in one direction when the image forming apparatus 100 is lifted.
[0148]
FIG. 10 is an enlarged view showing the configuration around the downward-rotatable handle 102b constituting the handle device according to the present embodiment. FIG. 10 shows a state in which the downward-rotating handle 102b is housed inside the image forming apparatus 100.
[0149]
As shown in FIG. 10, when the downward-rotating handle 102 b is stored inside the image forming apparatus 100, the lower-rotating handle 102 b is stored with its lower end locked by a locking member 1001 disposed below the grip 102 b. ing. At this time, the downwardly rotating handle 102b is housed in a state perpendicular to the image forming apparatus 100.
[0150]
The locking member 1001 includes a locking piece 1002 that enters the inside of the lower end of the downward-rotating handle 102b to regulate the rotation, and a support plate 1003 that supports a certain area near the lower end of the downward-rotating handle 102b. Consists of
[0151]
The downward-rotating handle 102b pivots around a pivot 1004, which is disposed at a position slightly higher than the upper end of the support plate 1003 of the locking member 1001. The rotating shaft 1004 has a flat shape having a major axis and a minor axis. As shown in the figure, the rotating shaft 1004 is fixed to the housing of the image forming apparatus 100 such that the major axis is horizontal to the image forming apparatus 100.
[0152]
An elongated hole portion 1005 is formed at a position corresponding to the rotating shaft 1004 in a lower region on a side surface of the vertically rotating handle 102b in a vertical state. The rotating shaft 1004 is inserted into the elongated hole 1005. The downward-rotating handle 102b rotates around the rotating shaft 1004 as a fulcrum inside the elongated hole 1005.
[0153]
As shown in the figure, the elongated hole 1005 has circular holes 1006a and 1006b at the upper end and the lower end having a diameter longer than the major axis of the rotating shaft 1004, and between these circular holes 1006a and 1006b. Has a connection hole 1007 for connecting the. The width of the connection hole 1007 is set to be substantially the same as the minor axis of the rotating shaft 1004. Therefore, when the rotating shaft 1004 moves through the connection hole 1007, it is necessary to move the connecting hole 1007 in accordance with the minor diameter of the rotating shaft 1004.
[0154]
A fixing portion 1008 is provided near the rotation shaft 1004 and inside the image forming apparatus 100 to fix the downwardly rotating handle 102b in a horizontal state. The fixing portion 1008 is configured to rotate the downwardly rotating handle 102b to hold the leading end of the downwardly rotating handle 102b in a horizontal state, and to hold the downwardly rotating handle 102b in a horizontal state. And a lock member 1010 as locking means for fitting.
[0155]
The holding portion 1009 has a box-like shape that is opened downward, and restricts rattling of the downwardly-rotating handle 102b in the side direction when the distal end of the downwardly-rotating handle 102b is held in a horizontal state. I do. At a predetermined position inside the image forming apparatus 100 in the holding unit 1009, a stopper 1011 for restricting entry of the distal end of the downward-rotatable handle 102b is provided. The presence of the stopper 1011 limits the downward rotation of the handle 102b from entering the image forming apparatus 100 more than necessary. The stopper 1011 is formed by pushing the surface of the holding portion 1009 inward.
[0156]
Thus, the holding portion 1009 for restricting the rattle of the downwardly-rotating handle 102b in the side direction is provided. Accordingly, when the image forming apparatus 100 is transported in a state where the downwardly rotating handle 102b is locked in a horizontal state, it is possible to prevent the downwardly rotating handle 102b from rattling in the left-right direction. It is possible to prevent the image forming apparatus 100 from swaying left and right and to ensure safe transportation.
[0157]
The lock member 1010 has a configuration in which a fitting piece is provided at a lower end portion, similarly to the lock member 203 of the upward-rotating handle 102a. The fitting piece protrudes downward through an opening formed at a predetermined position of the holding portion 1009, and fits into a fitting groove formed on the upper surface of the horizontally pivotable handle 102b. . The fitting state of the fitting piece and the fitting groove will be described later.
[0158]
The lock member 1010 is swingably attached to a support portion 1012 provided above the holding portion 1009. A coil spring 1013 as urging means is attached to the support 1012 at a position facing the upper end of the lock member 1010. The lock member 1010 is in a state of being urged downward by the urging force of the coil spring 1013 attached to the support 1012.
[0159]
FIG. 11 shows a state in which the downwardly rotating handle 102b according to the present embodiment is rotated and fixed in a horizontal state.
[0160]
The tip of the lower pivotable handle 102b in the horizontal state on the outer side of the image forming apparatus 100 is covered with a resin cover 1101 similarly to the upper pivotable handle 102a. The lower end of the resin cover 1101 has a shape that protrudes slightly below the lower end of the downward-rotating handle 102b. With the resin cover 1101 having such a shape, the hand of the carrier holding the downwardly rotating handle 102b is prevented from coming off from the distal end portion.
[0161]
Similarly to the upwardly-rotating handle 102a, the downwardly-rotating handle 102b is formed by, for example, bending, and the inside thereof is hollow. The lock release unit 1102 that moves in the horizontal direction is provided inside the hollow state.
[0162]
On the upper surface of the lock release portion 1102, a protruding portion 1103 slightly protruding near the surface on the resin cover 1101 side is provided. The protrusion 1103 is used when the carrier hooks a finger when the lock release unit 1102 is moved horizontally.
[0163]
Here, the structure of the lock release unit 1102 will be described with reference to FIG.
FIG. 18 is a cross-sectional view for explaining the structure of the unlocking portion 1102 of the downward-rotating handle 102b according to the present embodiment. Note that FIG. 18A shows a state in which the unlocking unit 1102 is not horizontally moved, and FIG. 18B shows a state in which the unlocking unit 1102 is horizontally moved.
[0164]
As shown in the drawing, inside the unlocking portion 1102, a coil as urging means for urging the inner wall 1801 of the tip portion on the resin cover 1101 side of the downwardly rotating handle 102b to the right side in the drawing. A spring 1802 is attached. When no force is applied by the urging force of the coil spring 1802, the lock release unit 1102 is in a state of being urged to the tip end on the resin cover 1101 side as shown in FIG. At this time, the left end of the lock release unit 1102 on the apparatus main body side is in a state of being slightly separated from a fitting piece of a lock member 1010 described later. On the other hand, the lock member 1010 is in a state of being inserted into a fitting groove formed on the upper surface of the below-described lower pivotable handle 102b by the urging force of the coil spring 1013.
[0165]
When the carrier pushes the protruding portion 1103 with a finger and horizontally moves the unlocking portion 1102, as shown in FIG. 18B, the inner wall 1801 of the distal end portion on the resin cover 1101 side applies the urging force of the coil spring 1802. Move to the left in the figure against. At this time, the left end of the lock release unit 1102 on the device body side contacts the fitting piece of the lock member 1010 and pushes the fitting piece upward from the fitting groove. When the carrier releases his / her finger from the protruding portion 1103, the unlocking portion 1102 returns to the state shown in FIG. 18A by the urging force of the coil spring 1802.
[0166]
As shown in FIG. 11, in a state where the handle 102b is fixed in a horizontal state, the tip of the downward-rotating handle 102b is held by the holding portion 1009 of the fixing portion 1008. At this time, the rotating shaft 1004 is housed in the circular hole 1006a via the connecting hole 1007 of the elongated hole 1005. The fitting piece of the lock member 1010 is fitted in a fitting groove formed on the upper surface of the downward-rotating handle 102b held by the holding portion 1009.
[0167]
Hereinafter, a description will be given of the movement of the downwardly rotating handle 102b having such a configuration from the vertical state to the horizontal state until it is fixed to the horizontal state.
[0168]
First, the downwardly rotating handle 102b shifts from the state shown in FIG. 10 to the state shown in FIG. Specifically, the carrier is turned so that the resin cover 1101 is pulled down toward the user so that the state shown in FIG. 12 is obtained. At this time, the downwardly rotating handle 102b rotates while the rotating shaft 1004 is housed in the circular hole 1006b of the elongated hole 1005. Since the circular hole 1006b has a diameter larger than the major axis of the rotating shaft 1004, the rotating shaft 1004 abuts on the circular hole 1006b to hinder the rotating operation of the downwardly rotating handle 102b. There is no.
[0169]
When the handle 102b is turned to the horizontal state, as shown in FIG. 13, a part of the tip of the downwardly-rotating handle 102b enters the inside of the holding portion 1009 from below. Also in this state, the rotating shaft 1004 is in a state of being housed in the circular hole 1006b of the elongated hole 1005.
[0170]
In FIG. 13, the downwardly-rotating handle 102b is in a state where only a small part of the tip is held by the holding portion 1009. In this state, the fitting groove formed on the upper surface of the downward-rotating handle 102b is not disposed below the lock member 1010, and the fitting piece of the locking member 1010 is located on the upper surface of the downward-rotating handle 102b. It has been pushed up by.
[0171]
Next, the downward-rotating handle 102b is pushed in the horizontal direction from the state shown in FIG. At this time, the rotating shaft 1004 moves through the connecting hole 1007 of the elongated hole 1005. As described above, since the rotating shaft 1004 is fixed in a state where the major axis is horizontal to the image forming apparatus 100, the rotating shaft 1004 contacts the connecting hole 1007 to rotate downward. The horizontal movement of the movable handle 102b is not hindered.
[0172]
When the downwardly-rotating handle 102b is pushed in, the fitting piece of the lock member 1010 is kept on the upper surface of the upwardly-rotating handle 102a until the fitting groove formed on the upper surface is disposed below the locking member 1010. Is maintained in a state of being pushed up. Then, when the fitting groove of the downwardly rotating handle 102b is pushed in until it is disposed below the lock member 1010, the fitting piece of the locking member 1010 enters the fitting groove of the downwardly rotating handle 102b, and FIG. The state shown in FIG.
[0173]
As described above, in the present image forming apparatus 100, when the downwardly rotating handle 102b is fixed in a horizontal state, the downwardly rotating handle 102b is rotated to the horizontal state, and then pushed toward the image forming apparatus 100, Further, the lock member 1010 is moved downward toward the upper surface of the downwardly rotating handle 102b in a horizontal state, and is fitted in the fitting groove to regulate the rotation of the downwardly rotating handle 102b. Therefore, simply turning the downward-rotating handle 102b to a horizontal state does not lock the lock, and requires two steps of operation before the lock is locked. Can be prevented and safe transportation can be guaranteed.
[0174]
Hereinafter, an operation when the locked state of the downwardly rotating handle 102b fixed in a horizontal state is released will be described. FIG. 14 is an enlarged view of the vicinity of a fitting groove formed on the upper surface of the downward-rotating handle 102b. Note that, in FIG. 14, for convenience of description, the display of the holding portion 1009 is omitted, and hereinafter, the fitting groove of the downwardly-rotating handle 102b and the fitting piece of the lock member 1010 are denoted by reference numerals. FIG. 14 shows a state in which the fitting piece 1401 of the lock member 1010 has entered the fitting groove 1402 formed on the upper surface of the downward-rotating handle 102b.
[0175]
When the fitting piece 1401 of the lock member 1010 enters the fitting groove 1402 formed on the upper surface of the downward rotating handle 102b, the downward rotating handle 102b fits the fitting piece 1401 and the fitting groove 1402. In some cases, it is in a state where it cannot be pulled out from the holding portion 1009 or rotated upward.
[0176]
In addition, the lock release portion 1102 provided inside the downward-rotating handle 102b has an inclined surface 1102a that goes down toward the fitting piece 1401 of the lock member 1010. When no force is applied to the unlocking portion 1102 in a state where the fitting piece 1401 of the lock member 1010 enters the fitting groove 1402 of the downwardly rotating handle 102b, the lock member 1010 is attached to the unlocking portion 1102. Due to the urging force of the coil spring, the inclined surface 1102a is arranged slightly outside the device from the fitting piece 1401 of the lock member 1010.
[0177]
FIG. 15 shows a state where the fitting piece 1401 of the lock member 1010 is pushed upward by the lock release unit 1102.
[0178]
When the lock release unit 1102 is pushed inward by the carrier from the state shown in FIG. 14, the inclined surface 1102a moves to the fitting piece 1401 side of the lock member 1010 as shown in FIG. The fitting piece 1401 of the lock member 1010 abutting on the slope 1102a moves so as to climb the slope of the slope 1102a. As a result, the fitting piece 1401 of the lock member 1010 comes out of the fitting groove 1402 of the downward-rotating handle 102b. At this time, the downwardly-rotating handle 102b is in a state where it can be pulled out from the holding portion 1009. The lock of the downwardly rotating handle 102b fixed in a horizontal state in this manner is released.
[0179]
When storing the unlocked downwardly rotating handle 102b in the image forming apparatus 100, the carrier performs an operation opposite to the operation until the handle is fixed in a horizontal state. That is, after the downwardly rotating handle 102b is pulled out to the outside of the apparatus, the distal end portion of the downwardly rotating handle 102b is rotated upward.
[0180]
As described above, in the present image forming apparatus 100, when the downward-rotatable handle 102b is housed inside the apparatus, the unlocking portion 1102 is horizontally moved to the lock member 1010 side to push the lock member 1010 upward, and the fitting groove is formed. In addition to releasing the fitting with the 1402, the downwardly rotating handle 102b can be rotated upward after the downwardly rotating handle 102b is pulled out of the apparatus. For this reason, two steps of operation are required until the downwardly rotating handle 102b is rotated, so that the lock is unlikely to be locked immediately when the downwardly rotating grip 102b is immediately rotated by releasing the lock member 1010. Even if it is accidentally released, the downwardly rotating handle 102b does not suddenly rotate, and safety can be reliably ensured.
[0181]
Note that, in the present embodiment, a case is described in which, when the downwardly rotating handle 102b is rotated and then pushed into the inside of the image forming apparatus 100, it is pushed by the carrier. However, the present invention is not limited to this, and it is conceivable to attach a coil spring as an urging means for urging the downward-rotatable handle 102b to the inside of the apparatus and automate the operation of pushing the handle into the inside of the apparatus. For example, as shown in FIG. 19, it is conceivable to attach the other end of the coil spring 1902 having one end attached to the locking portion 1901 provided inside the downwardly-rotating handle 102b to the rotating shaft 1004.
[0182]
In this case, after rotating to the horizontal state, the downwardly-rotating handle 102b is pulled inward by the urging force of the coil spring 1902. As a result, the downward-rotating handle 102b automatically horizontally moves toward the inside of the apparatus. In the case of such a change, in addition to the effect of the present embodiment, since the downwardly rotating handle 102b can be automatically locked after being rotated in the horizontal state, it is possible to forget to apply the lock beforehand. This has the effect of reliably preventing and ensuring safe transportation. In addition, since the urging means attached to the downward-rotating handle 102b is constituted by a coil spring, the urging means can be easily and easily realized without increasing the size, thereby realizing a reduction in size and cost of the apparatus. it can.
[0183]
Here, the positional relationship between the locking member 1001 and the locking piece 1002 and the positional relationship between the locking member 1001 and the rotating shaft 1004 when the downwardly rotating handle 102b shifts from the vertical state to the horizontal state will be described. FIG. 16 is a view for explaining the positional relationship between the locking member 1001 and the locking piece 1002 and the positional relationship between the locking member 1001 and the rotating shaft 1004 when the downwardly rotating handle 102b shifts from the vertical state to the horizontal state. It is a schematic diagram.
[0184]
FIG. 16A is a schematic diagram corresponding to the state of the downward-rotating handle 102b shown in FIG. As shown in the figure, the lower end of the downward-rotating handle 102b is locked by a locking piece 1002 of a locking member 1001.
[0185]
The locking piece 1002 has a shape that protrudes upward slightly to the left from the right wall surface in FIG. 16A at the lower end of the downwardly rotating handle 102b. Specifically, the locking piece 1002 has two slopes that rise slightly toward the left vertex from the right wall surface in FIG. 16A at the lower end of the downward-rotating handle 102b. Take shape. The right-hand wall surface in FIG. 16A at the lower end of the downward-rotating handle 102b goes over the top of the locking piece 1002 into the right-hand side shown in FIG. 102b is in a locked state.
[0186]
In this state where the downwardly rotating handle 102b is housed inside the apparatus, the lower end of the downwardly rotating handle 102b is locked by the locking piece 1002. To be exposed to the outside of the apparatus. When the downwardly rotating handle 102b is locked in the vertical state, the rotating shaft 1004 is housed in the circular hole 1006b of the elongated hole 1005.
[0187]
