A mask dispensing assembly includes a housing that is positionable in a public transportation vehicle and the housing has a dispensing slot extending into an interior of the housing to dispense face masks stored in the housing to the passengers. A lifting unit is positioned within the housing to lift a stack of disposable face masks in the housing thereby aligning a topmost one of the stack of disposable face masks with the slot. A dispenser is positioned in the housing to urge the topmost one of the stack of disposable face masks outwardly through the slot. A switch is positioned in the public transportation and the lifting unit is actuated when the switch is depressed to facilitate the driver to dispense a disposable mask for a passenger to wear.

In order to downsize an overall apparatus without setting the swing angle of a swing member to be unnecessarily large, a pickup roller, which is for feeding a document disposed on a feeding tray, is supported by a pickup arm that is swingable about a rotation shaft. Depending on the rotational direction of the rotation axis, the pickup arm swings between a first position, in which the pickup roller is in contact with the document on the feeding tray, and a second position, in which the pickup roller is above and not in contact with the feeding tray. An arm member is rotated by rotation of the rotation axis after the pickup arm swings to the second position.

A sheet conveying apparatus includes a conveyance unit to convey a sheet, a support frame supporting the he conveyance unit and having a mounting member, and an exterior cover made of metal and fixed to the mounting member by a screw. The exterior cover covers the support frame on a back side of the sheet conveying apparatus and includes a hook portion provided above a position corresponding to the mounting member in a vertical direction, and a positioning pin provided below the position corresponding to the mounting member in the vertical direction. The support frame includes an engagement portion, engaged with the hook portion and provided at a position above the mounting member in the vertical direction, and a through-hole, formed at a position below the mounting member in the vertical direction, into which the positioning pin is inserted to position the exterior cover with respect to the support frame.

There is provided a medium transporting device including: a medium placement section on which a medium is placed, a feeding roller feeding a medium from the medium placement section, a motion detection sensor detects a motion of a medium, and a controller that stops feeding of a medium based on a detection value received from the motion detection sensor, in which the motion detection sensor is a two-dimensional sensor including a light emitting section and a light receiving section and detecting a motion of a medium, the medium placement section is provided with a placement detector that acquires information relating to a presence/absence of a medium on the medium placement section, and the controller sets a state of the light emitting section to a non-light emitting state when detection information of the placement detector indicates that a medium is absent on the medium placement section.

Systems and methods of non-contact tensioning of a metal strip during metal processing include passing the metal strip adjacent a magnetic rotor. The magnetic rotor is spaced apart from the metal strip by a first distance. The systems and methods also include tensioning the metal strip through the magnetic rotor by rotating the magnetic rotor. Rotating the magnetic rotor induces a magnetic field into the metal strip such that the metal strip is tensioned in an upstream direction or a downstream direction. In other aspects, rotating the magnetic rotor induces a magnetic field into the metal strip such that a force normal to a surface of the metal strip is applied to the metal strip.
