Tipping prevention unit, feeding apparatus, and image forming apparatus
A tipping prevention unit that prevents tipping of an image forming apparatus includes shafts holding a wheel of the image forming apparatus, a shaft that abuts the image forming apparatus at a position higher than the shafts, and a shaft that contacts a floor surface on which the image forming apparatus is placed at a position further protruding to the outside of the image forming apparatus than the wheel of the image forming apparatus.
1. A tipping prevention unit mounted on an image forming apparatus having a wheel and for preventing tipping of the image forming apparatus, comprising:
a main body portion of the tipping prevention unit;
a first holding shaft protruding from the main body portion, the first holding shaft contacting a wheel of the apparatus;
a second holding shaft protruding from the main body portion, the second holding shaft contacting the wheel of the image forming apparatus,
wherein the second holding shaft is arranged at a position higher than the first holding shaft,
an abutting shaft protruding from the main body portion, the abutting shaft abutting the image forming apparatus at a position higher than the first holding shaft and the second holding shaft;
a contacting shaft protruding from the main body portion, the contacting shaft contacting a floor surface on which the image forming apparatus is placed,
wherein respective central axes of the first holding shaft, abutting shaft, and contacting shaft form endpoints of an imaginary triangular area and the second holding shaft is located entirely within the triangular area;
wherein the first holding shaft, the second shaft, the abutting shaft, and the contacting shaft each have a proximal end connected to the main body and a free distal end,
wherein the first holding shaft and the second holding shaft regulate a rotation of the wheel by each coming into contact with the wheel, and
wherein the first holding shaft, the second shaft, the abutting shaft, and the contacting shaft are parallel with respect to each other.
2. The tipping prevention unit according to claim 1 ,
wherein the contacting shaft contacts with the floor surface where the image forming apparatus is placed on at a portion away from the wheel.
3. The tipping prevention unit according to claim 1 ,
wherein the main body portion, the first holding shaft, the second holding shaft, the abutting shaft, and the contacting shaft are integral.
4. The tipping prevention unit according to claim 1 ,
wherein the tipping prevention unit can be attached to and detached from the image forming apparatus from a direction of an axis of the contacting shaft.
