Abstract:
A sheet conveying device includes a sheet cassette including a first housing, a pressing plate, a raising plate, a first resilient member, and a second resilient member. The sheet conveying device further includes a second housing, a sheet-cassette accommodating portion, a first electrode, a second electrode, a sheet conveyor, a driver, a first signal output device, and a second signal output device. When controlling the driver to move the raising plate to move the pressing plate upward, the controller detects a state change in the first signal output device from not outputting a conduction signal to outputting the conduction signal; upon this detection, starts counting the number of pulse signals; and determines an amount of upward movement of the pressing plate based on the counted number.

Claim (Index 12):
An image forming apparatus comprising:\n a sheet conveying device including:\n a sheet cassette including:\n (i) a first housing configured to accommodate sheets; \n (ii) a pressing plate formed of a conductive material, provided at the first housing, and movable upward and downward while supporting the sheets; \n (iii) a raising plate formed of a conductive material, provided at the first housing, and movable from a spaced position at which the raising plate is spaced from the pressing plate to and beyond an initial contact position at which the raising plate contacts the pressing plate and starts moving the pressing plate upward; \n (iv) a first resilient member formed of a conductive material and provided at the first housing, the first resilient member including a first end portion in contact with the movable pressing plate, and a second end portion; and \n (v) a second resilient member formed of a conductive material and provided at the first housing, the second resilient member including a first end portion in contact with the movable raising plate, and a second portion; \n \n a second housing; \n a sheet-cassette accommodating portion provided at the second housing and accommodating the sheet cassette; \n a first electrode provided at the sheet-cassette accommodating portion and in contact with the second end portion of the first resilient member; \n a second electrode provided at the sheet-cassette accommodating portion and in contact with the second end portion of the second resilient member; \n a sheet conveyor provided at the second housing and configured to convey a sheet from the pressing plate; \n a driver provided at the second housing and configured to move the raising plate, the driver including:\n (a) a motor configured to supply a driving force; and \n (b) a transmission mechanism configured to transmit to the raising plate the driving force supplied from the motor; \n \n a first signal output device configured to output a conduction signal when the first electrode and the second electrode are electrically connected to each other; \n a second signal output device configured to output pulse signals indicating an amount of rotation of the motor; and \n a controller configured to, when controlling the driver to move the raising plate to move the pressing plate upward:\n detect a state change in the first signal output device from not outputting the conduction signal to outputting the conduction signal, the state change corresponding to a positional change of the raising plate from the spaced position to the initial contact position; \n upon detection of the state change in the first signal output device, start counting the number of pulse signals received from the second signal output device; and \n determine an amount of upward movement of the pressing plate based on the counted number of pulse signals; and \n \n an image former provided in the second housing and configured to form an image on the sheet conveyed from the sheet conveying device by the sheet conveyor.
