An image forming apparatus includes a tray; a casing having a first outlet, a second outlet above the first outlet, a first path, and a second path; a stack lever; a drive source; and a controller. The second path communicates with the second outlet such that a sheet conveyed along the second path is partially discharged from the second outlet and is reversed along the second path. The first outlet communicates with the first path such that the sheet conveyed along the first path is discharged from the first outlet onto the tray. The stack lever is movable between a first position where the stack lever presses a sheet on the tray and a second position higher than the first position. The controller is configured to control the drive source such that, when the sheet is discharged from the second outlet, the stack lever is at the second position.

The present invention relates to a device (20) for winding a longitudinally cut material web having multiple longitudinal strips (12) on a plurality of winding tubes (16) to form in each case a wound roll. The device comprises an axle (24) and, mounted on the axle, a plurality of ring-shaped winding drives (22) that are individually controllable in their operating position. Each winding drive (22) forms an external-rotor electric motor and comprises a static interior tube (40) and a rotatable external tube (50). The external tube (50) that is rotatable on the rolling bearings (48) bears, on its interior, a device for providing an excitation magnetic field (52) that forms the external rotor of the electric motor.

Apparatus and associated methods relate to a handheld power-dispensing tape dispenser having a center of gravity forward of a user's hand. In an illustrative example, a tape dispenser may, for example, include a housing having a handle configured to be held by a human hand. A first roller body may, for example, be rotatably coupled to the housing to rotate about a first axis. A motor may, for example, be disposed in the first roller body. An actuator may, for example, be configured such that, in response to operation of the actuator by a user, the motor induces rotation of the first roller body about the first axis. A second roller body may, for example, be rotatably coupled to the housing and configured to rotate about a second axis substantially parallel to the first axis. Various implementations may advantageously increase stability and/or reduce operator fatigue during taping operations.

A motor driver drives a motor that controls a position of an object based on a command from a controller. The motor driver includes: a correction command output part that outputs a correction command for correcting a position of the motor based on a position of the object detected by a displacement sensor that detects the position of the object; and a position controller that outputs a drive signal for driving the motor based on the command from the controller and the position of the motor detected by an encoder that detects the position of the motor, or based on the correction command and the position of the motor detected by the encoder.

A web material advancement arrangement is provided with an entry drive system. The web material advancement arrangement can receive a web material from a storage roll and advance the web material through a machine, such as a packaging machine. The entry drive system may be arranged at the entry end of the web material advancement arrangement to push the web material in a downstream direction from the entry end toward the exit end of the web material advancement arrangement The entry drive system may include a motor that simultaneously rotates a pair of drive sprockets which may push clip assemblies that carry outer edges of a web material so that rotation of the drive sprockets pushes the web material in a downstream direction.

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.
