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; a second housing; a sheet-cassette accommodating portion; a first electrode; a second electrode; a sheet conveyor; a driver; a first output device that outputs a first signal and a second signal; a second output device that outputs a rotation pulse signal; and a controller that receives the first signal, the second signal, and the rotation pulse signal. The controller counts pulses of the rotation pulse signal received from the second output device, determines the number of pulses of the rotation pulse signal, and determines an amount of upward movement of the pressing plate based on the number of pulses of the rotation pulse signal.

Claim (Index 7):
A sheet conveying device, comprising:\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 between a first position and a second position while supporting the sheets, the first position being a lowest position of the pressing plate, the second position being located above the first position; \n (iii) a raising plate formed of a conductive material, provided at the first housing, and configured to move the pressing plate between the first position and the second position while being in constant contact with the pressing plate; \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 and a second end portion, the first end portion being configured to contact the pressing plate when the pressing plate is located above the first position, the second end portion being partially located outside the first housing; and \n (v) a second resilient member provided at the first housing, the second resilient member including a first end portion and a second end portion, the first end portion being in contact with the raising plate during movement of the raising plate, the second end portion being partially exposed to an outside of the first housing; \n a second housing; a sheet-cassette accommodating portion provided at the second housing and configured to accommodate the sheet cassette; a first electrode provided at the sheet-cassette accommodating portion and configured to be in contact with the second end portion of the first resilient member when the sheet cassette is accommodated in the sheet-cassette accommodating portion; a second electrode provided at the sheet-cassette accommodating portion and configured to be in contact with the second end portion of the second resilient member when the sheet cassette is accommodated in the sheet-cassette accommodating portion; a sheet conveyor provided at the second housing and configured to convey the sheets from the pressing plate; a driver provided at the second housing and configured to move the raising plate, the driver including (i) a motor configured to supply a driving force and (ii) a transmission mechanism configured to transmit the driving force supplied from the motor to the raising plate when the sheet cassette is accommodated in the sheet-cassette accommodating portion; a first output device including a detector configured to detect that an uppermost sheet of the sheets supported on the pressing plate reaches a particular position by upward movement of the pressing plate, the detector including (i) a light emitter configured to emit light when receiving electric power, (ii) a light receiver configured to receive the light emitted from the light emitter, and (iii) an actuator being located between the light emitter and the light receiver to intercept the light emitted from the light emitter when the actuator is being moved in contact with the sheet supported on the pressing plate, the actuator being not located between the light emitter and the light receiver to allow the light receiver to receive the light emitted from the light emitter when the actuator is not in contact with the sheet, the first output device being configured to:\n output a first signal when the light emitter is receiving electric power and the actuator is not located between the light emitter and the light receiver; \n output a second signal when the light emitter is receiving electric power and the actuator is located between the light emitter and the light receiver; and \n output the second signal when the light emitter is not receiving electric power; \n a controller configured to receive the first signal and the second signal, the controller being configured to output a supply command to supply electric power to the light emitter of the first output device; and a power supply circuit configured to:\n receive the supply command from the controller when the first electrode and the second electrode are not electrically connected to each other by separation between the pressing plate and the first end portion of the first resilient member; \n supply electric power to the light emitter of the first output device when the power supply circuit receives the supply command from the controller; \n supply no electric power to the light emitter when the power supply circuit does not receive the supply command from the controller; and \n supply electric power to the light emitter when the first electrode and the second electrode are electrically connected to each other by contact between the pressing plate and the first end portion of the first resilient member, \n wherein the controller is configured to:\n receive the first signal from the first output device in response to transmitting the supply command to the power supply circuit; \n stop transmitting the supply command to the power supply circuit in response to receiving the first signal from the first output device; \n receive the second signal from the first output device in response to stopping transmitting the supply command to the power supply circuit; and \n provide a notification about a failure when the controller does not receive the first signal when a particular length of time is elapsed from a stop of transmission of the supply command.
