A sheet supporting apparatus includes a sheet supporting portion, a regulation member, a flag portion, a detection portion, and a holding portion con. At the holding position, the holding portion supports the flag portion at the upper position in a case where the sheet supporting portion is positioned at the first position, and, at the allowing position, the holding portion allows movement of the flag portion to the lower position in a case where the sheet supporting portion is positioned at the second position. A lower end of the flag portion is positioned above the regulation surface in a case where the flag portion is positioned at the upper position, and is positioned below the regulation surface in a case where the flag portion is positioned at the lower position.

The present disclosure is in one aspect to a dispenser for rolled sheet materials. The dispenser includes a feed roller that is rotatably mounted to a housing of the dispenser housing, and that is configured to feed a predetermined amount of sheet material from the supply of sheet material through a discharge provided along the housing of the dispenser. The dispenser also has a feed roller drive assembly with a drive motor, and a belt transmission assembly. The belt transmission assembly has a drive belt coupled to the drive motor and to the feed roller such that rotation of the feed roller is driven by operation of the drive motor.

A lifting system for inner yarn rails is provided. The system includes an in-air conveying rail, and a carrier unit, wherein the in-air conveying rail is configured to convey the carrier unit, and the carrier unit is configured to carry a winding package; an inner yarn-carrier-lifting section is arranged on the in-air conveying rail, the inner yarn-carrier-lifting section is positioned on both sides of a twisting machine; when the inner yarn-carrier-lifting section rises, it communicates with the in-air conveying rail; when the inner yarn-carrier-lifting section descends, it approaches the position of a spindle bucket of the twisting machine.

A transport module for flat items comprising at least one transport element borne in a transport element carrier having a drive shaft is designed for installation in a station of an item processing system and, after installation, is borne rotatably around an axis of the drive shaft. It is one of multiple transport modules of an identical design. The transport element has, on one side, a lower friction coefficient than on the other side of an equator and is driven by the drive shaft via transmission means of the transport module. The transport element carrier carries the transmission means of the transport module and has a spring assembly allowing it to be shifted in the direction of gravity and contrary to it.

An image forming apparatus that controls to cut off exciting currents supplied to a plurality of motors to drive conveyance roller pairs after a leading end of a paper sheet is brought in contact with a registration roller pair, and, when cutting off the exciting currents, cut off the exciting current for at least one of the motors at a different timing from the other motors.

The present invention is to provide a power tape dispenser which capable to automatically dispense and cut packaging tape at a desired speed. The operations of the tape dispenser such as taping and cutting process are controlled by the engagement of surface triggering device, the main triggering device and the electrical components.

A motor control device includes: an electric-current detection unit configured to detect an electric current that flows through a motor at a time when the motor is not to be driven; a voltage-polarity determining unit configured to determine polarity of a voltage corresponding to the detected electric current; and an operating-state management unit configured to perform control of stopping the motor depending on the polarity of the voltage.

In one example in accordance with the present disclosure a media transport device is described. The device includes a number of drive rollers coupled to a frame. A number of media rollers are also coupled to the frame. The media rollers are in contact with, and rotated by, the number of drive rollers. Media rollers in a first set have a first diameter and media rollers in a second set have a second diameter that is different from the first diameter. The device also includes a number of pinch rollers coupled to the frame. The pinch rollers are in contact with the number of media rollers to form a number of nips through which media passes along a feed path.

To control a winding drive current of a motor based on a command phase representing a target phase of a rotor of the motor, a motor control apparatus includes a filter circuit, a phase determiner, and a controller. A current value of the drive current flowing through the winding is obtained at a predetermined period. The filter circuit reduces a harmonic component in a fundamental frequency of the drive current included in a signal indicated by the obtained current value. The phase determiner determines a rotation phase of the rotor based on a filter processed signal. The controller controls the winding drive current to reduce a deviation between the command phase and the determined rotation phase. The filter circuit reduces a harmonic component from a signal indicated by current values of which a number is not greater than a number of the current values obtained at the predetermined period.

An image forming apparatus includes: an image-forming mechanism; a reconveying roller; an electric motor; and a transmission mechanism. The transmission mechanism is configured to operate in one of a reverse-rotation transmission mode for reversing a direction of a rotational force received from the electric motor to transmit the reversed rotational force to the reconveying roller and a normal-rotation transmission mode for transmitting the rotational force to the reconveying roller without reversing the direction of the rotational force. The transmission mechanism includes an interrupting unit for interrupting transmission of a rotational force from the reconveying roller to the electric motor at least when a sheet is being conveyed in the image-forming mechanism. The transmission mechanism is configured to interrupt transmission of the rotational force received from the electric motor to the reconveying roller when a sheet is being conveyed in the image-forming mechanism.
