The operation unit 223 can be operated by a worker. Specifically, the worker can move the operation unit 223 along the operation direction S2. The operation direction S2 is the X-axis positive direction. By moving the operation portion 223 along the operation direction S2, the tip end 222a of the projecting member 222 can be swung with the fulcrum member 212b as the swing fulcrum. The operation portion 223 is provided at an end portion of the protruding member 222 opposite to the tip end 222a. The operation unit 223 is located outside the apparatus main body 20 described with reference to FIG.

As shown in FIG. 2B, the second joint portion 211 is in contact with the first joint portion 121.

As shown in FIGS. 2A and 2B, the guide member 212a and the fulcrum member 212b are linearly arranged in the Y-axis direction. The guide member 212a and the fulcrum member 212b are cylindrical members. As described with reference to FIG. 6A, the side surface of the fulcrum member 212b comes into contact with the projecting member 222 when the projecting member 222 swings.

As shown in FIG. 2C, the second joint portion 211 has a second slope 211a that contacts the first slope 121a. The second slope 211a is an example of a second contact surface. When the second slope 211a and the first slope 121a are in contact with each other, the second slope 211a and the first slope 121a are substantially in contact with each other. Hereinafter, the state where the first slope 121a and the second slope 211a are in contact with each other will be referred to as a “first contact state”.

Next, an operation of fixing the image forming apparatus 100 according to the present embodiment to the installation surface G will be described with reference to FIGS. 1 to 6. Also, an operation of releasing the fixation of the image forming apparatus 100 to the installation surface G will be described.

The operation of fixing the image forming apparatus 100 to the installation surface G is started by the worker moving the supply device 10 to the installation surface G. Specifically, the worker moves the supply device 10 to the installation surface G while rotating a caster 15 by manually pushing a part of the housing 11 of the supply device 10.

After moving the supply device 10 to the installation surface G, the operator places the device main body 20 on the supply device 10. Specifically, the worker pulls out the handle 22 from the first storage portion 21 of the device body 20 and lifts the device body 20 using the handle 22. The operator moves the lifted device body 20 onto the supply device 10.

Specifically, the operator moves the apparatus main body 20 so that the positioning hole 214a is located on the positioning member 141 and the positioning hole 214b is located on the positioning member 142 described in FIG. After that, the worker moves the device body 20 toward the negative side of the Z axis and places the device body 20 on the supply device 10.

With reference to FIG. 3, a state in which the device body 20 is placed on the supply device 10 will be described. FIG. 3 is a cross-sectional view showing the configuration of the image forming apparatus 100 according to this embodiment.

As shown in FIG. 3, when the device body 20 is placed on the supply device 10, the first joint part 121 is housed in the first housing part 21. As a result, the entire first slope 121a and the second slope 211a described with reference to FIG. 2 come into contact with each other.

Immediately after the device body 20 is placed on the supply device 10, the handle 22 is not housed in the device body 20. Therefore, the tip of the handle 22 is not in contact with the first joint portion 121, and the moving mechanism T is in the state shown in FIG.

The operator places the device body 20 on the supply device 10, and then stores the handle 22 in the first storage portion 21. A state in which the handle 22 is stored in the first storage portion 21 will be described with reference to FIGS. 4A and 4B. FIG. 4A is a sectional view of the image forming apparatus 100 according to this embodiment. FIG. 4B is a sectional view taken along the line IVB-IVB in FIG.

As shown in FIG. 4A, when the handle 22 is stored in the first storage portion 21, the tip of the handle 22 contacts the first joint portion 121. More specifically, as shown in FIG. 4B, when the handle 22 is stored in the first storage portion 21, the handle 22 passes through the positioning member 141 and the passage hole 141a of the positioning member 142, and the first joint. Abut on the part 121.

As shown in FIG. 4B, a slit is formed on the upper wall of the second joint portion 211. The slit extends along the storage direction S1. The guide member 212a is fitted in the slit. As a result, the handle 22 is guided in the storage direction S1 by the guide member 212a. When the handle 22 is stored in the first storage portion 21, the fulcrum member 212b also fits in the slit. In addition, in this embodiment, the protruding member 222 is formed by bending a sheet metal.

Next, with reference to FIG. 5A to FIG. 5C, the operation of the moving mechanism T when the tip of the handle 22 contacts the first joint portion 121 will be described.

5A to 5C are diagrams showing the configuration of the moving mechanism T according to the present embodiment. Specifically, FIG. 5A is a diagram of the moving mechanism T as viewed toward the negative side of the Z axis. However, like FIG. 2A, FIG. 5A shows only the guide member 212a and the fulcrum member 212b for the first storage portion 21. Further, in FIG. 5A, the upper wall of the second joint portion 211 is omitted. FIG. 5B is a view of the moving mechanism T as viewed toward the X-axis positive side. However, similarly to FIG. 2B, FIG. 5B shows only the second joint portion 211, the guide member 212a, and the fulcrum member 212b for the first storage portion 21. FIG. 5C is a view of the first joint part 121 and the second joint part 211 as viewed toward the Y-axis positive side.

As shown in FIG. 5A, the tip of the handle 22 contacts the first joint portion 121. Specifically, the tip end 222a of the protruding member 222 contacts the first cutout surface 121d of the first joint portion 121.

As shown in FIG. 5B, when the tip end 222a of the projecting member 222 moves in the storage direction S1 while contacting the first cutout surface 121d, the first joint portion 121 rotates in the first rotation direction R1. When the first joint portion 121 rotates in the first rotation direction R1, the first contact state of the first joint portion 121 is released. That is, the state in which the first slope 121a is in contact with the second slope 211a is released. When the first contact state is released, the release surface 121b comes into contact with the second slope 211a. That is, the first joint portion 121 is in the second contact state.

As shown in FIG. 5C, when the first joint part 121 is in the second contact state, the release surface 121b contacts only the lower end of the second sloped surface 211a. In other words, a gap is created between the release surface 121b and the second slope 211a. That is, a gap is created between the first joint part 121 and the second joint part 211. Therefore, when the first joint portion 121 changes from the first contact state to the second contact state, the first joint portion 121 and the second joint portion 211 are separated from each other. As a result, the first joint part 121 moves in the first direction D1.

When the first joint part 121 moves in the first direction D1, the shaft part 122 and the contact part 123 described with reference to FIG. 1 also move in the first direction D1. Therefore, the contact portion 123 contacts the installation surface G. As a result, the image forming apparatus 100 is fixed to the installation surface G.

Next, with reference to FIGS. 6A to 6C, the operation when releasing the fixation of the image forming apparatus 100 will be described. FIG. 6 is a diagram showing the configuration of the moving mechanism T according to the present embodiment. Specifically, FIG. 6A is a view of the moving mechanism T as viewed toward the negative side of the Z axis. However, FIG. 6A shows only the guide member 212a and the fulcrum member 212b for the first storage portion 21, as in FIG. 2A. Moreover, in FIG. 6A, the upper wall of the second joint portion 211 is omitted. FIG. 6B is a diagram of the moving mechanism T viewed toward the X-axis positive side. However, similarly to FIG. 2B, FIG. 6B shows only the second joint portion 211, the guide member 212a, and the fulcrum member 212b for the first storage portion 21. FIG. 6C is a view of the first joint part 121 and the second joint part 211 as viewed toward the Y-axis positive side.

The operation of releasing the fixation of the image forming apparatus 100 to the installation surface G is started by the operator operating the operation unit 223.

As shown in FIG. 6A, the operator moves the operation unit 223 along the operation direction S2. When the operation portion 223 moves, the guide member 212a is stored in the third storage portion 222b of the projecting member 222. When the operation portion 223 moves, the side surface of the protruding member 222 contacts the side surface of the fulcrum member 212b, and the protruding member 222 swings with the fulcrum member 212b as a swing fulcrum. As a result, when the operating portion 223 moves, the contact destination of the tip end 222a of the protruding member 222 is changed from the first cutout surface 121d to the second cutout surface 121e.

As shown in FIGS. 6A and 6B, when the tip end 222a of the protruding member 222 contacts the second cutout surface 121e, the first joint portion 121 rotates in the second rotation direction R2. .. When the first joint part 121 rotates in the second rotation direction R2, the second contact state of the first joint part 121 is released. When the second contact state is released, the first joint part 121 enters the first contact state. That is, the first slope 121a and the second slope 211a are in contact with each other.

As shown in FIG. 6C, when the first joint portion 121 is in the first contact state, the entire first slope 121a and the second slope 211a are in contact with each other. Therefore, the 1st joint part 121 and the 2nd joint part 211 approach. As described with reference to FIG. 1, the biasing member 13 biases the fixing member 12 in the second direction D2. Therefore, the first joint part 121 moves in the second direction D2 when the first joint part 121 changes from the second contact state to the first contact state.

When the first joint portion 121 moves in the second direction D2, the shaft portion 122 and the contact portion 123 described with reference to FIG. 1 also move in the second direction D2. Therefore, the contact portion 123 moves away from the installation surface G. As a result, the fixation of the image forming apparatus 100 to the installation surface G is released.

As described above with reference to FIGS. 1 to 6, in the image forming apparatus 100 of the present embodiment, when the handle 22 is stored in the first storage portion 21, the tip of the handle 22 becomes the fixing member 12. The fixing member 12 contacts the first joint portion 121 and moves in the first direction D1 while rotating. As a result, the contact portion 123 at the lower end of the fixing member 12 contacts the installation surface G, and the image forming apparatus 100 can be fixed to the installation surface G.
