Abstract
One or more toner bottles are provided for supplying toners to development apparatuses. The toner bottles each include bottle portions and displacement sensors. The bottle portions accommodate the toners and are rotated by a drive force of a drive source. The displacement sensors are positioned on sides of the bottle portions and detect deflection amounts of the sides of the bottle portions to determine how much toner is remaining in each toner bottle.
Claims17
A toner bottle for supplying toner to a development apparatus, the toner bottle comprising:
- a bottle portion configured to accommodate the toner and to rotate by a drive force applied by a drive source;
- a displacement sensor disposed in a center region of a side of the bottle portion and configured to detect a deflection amount of the side of the bottle portion;
- and
- a control unit configured to calculate an amount of the toner accommodated in the bottle portion based on the deflection amount detected by the displacement sensor, with the calculated amount of toner based on a maximum value and a minimum value of electric signals detected by the displacement sensor.
A toner bottle that indicates an amount of toner accommodated therein, the toner bottle comprising:
- a toner container configured to accommodate the toner for creating an image;
- a displacement sensor disposed in a center of a side of the toner container and configured to detect a deflection amount of the toner container, the deflection amount being based on an amount of toner in the toner container;
- a control unit configured to calculate the amount of the toner in the toner container based on the deflection amount detected by the displacement sensor, with the calculated amount of toner based on a maximum value and a minimum value of electric signals detected by the displacement sensor;
- and
- a notification unit configured to display a notification of the calculated amount of the toner calculated by the control unit.
A toner bottle that indicates an amount of toner accommodated therein, the toner bottle comprising:
- a bottle portion configured to accommodate the toner for creating an image;
- a twist sensor disposed in a center region of the bottle portion and having a fixed end coupled to bottle portion with a free end extending in a space defined by the bottle portion;
- a control unit configured to calculate an amount of the toner in the bottle portion based on a detection result generated by the displacement sensor;
- and
- a rotor disposed in the cylindrical bottle portion and configured to rotate to output the toner from the cylindrical bottle portion,
- wherein the twister sensor is configured to detect an amount of toner when the rotor rotates and output the detection result to the control unit, and
- wherein the twister sensor comprises a substrate with a first portion extending in a lengthwise direction of the bottle portion and including the fixed end and a second portion disposed opposite the fixed end an extending orthogonally to the first portion for detecting the amount of the toner when the rotor rotates.
