Abstract: A braking assembly used in a dispenser that dispenses a continuous supply of material such as paper. The braking assembly includes a support structure. A first fixed gear is rotatably connected to the support structure. A movable chassis is also connected to the support structure. A second movable gear is held by the chassis and moves with the chassis. Teeth of the first gear and teeth of the second gear intermesh with each other and allow the paper to pass therethrough. The chassis maintains the teeth of the first and second gears in contact with each other while enabling a distance between gears to be adjustable. The assembly further includes a braking mechanism that varies an amount of force required to rotate the gears.

Abstract: A paper feeding device that feeds a sheet of a paper roll to a printing device includes two spaced-apart side plates having opposed first notches for rotatably bearing-supporting a first paper roll and opposed second notches for rotatably bearing-supporting a second paper roll that may have a different diameter in an unused state from that of the first paper roll. A near end sensor for detecting the remaining amount of the paper rolls is slidably positioned in a linear groove formed in one of the side plates. The linear groove having a longitudinal axis that passes through a midpoint of a straight line connecting a rotation center of a first paper roll bearing-supported in the first notches and a rotation center of a second paper roll bearing-supported in the second notches. When first and second paper rolls of different sizes are used, if both paper rolls are wound on paper tubes of the same size, the position of the near end sensor need not be changed, which is a great convenience for the user.

Abstract: Transmissions and drive systems for a self-propelled machine and related methods are provided. An input shaft having an axis and extending transverse to an output shaft is provided. The input shaft can be rotatable about the axis of the input shaft and configured to drivingly engage the output shaft. A variable pitch pulley can be disposed axially on the input shaft and configured to rotate about the axis of the input shaft. The variable pitch pulley can be configured to change pitch diameter to regulate the speed at which the input shaft is rotated. Further, the input shaft can be at least partially rotatable about an axis of the output shaft to vary the pitch of the variable pitch pulley to regulate the speed at which the input shaft drives the output shaft.

Abstract: A driving force transmission apparatus includes: a motion power transmission part for transmitting a motion power via a driving medium formed by a belt or a chain; and a tensioner for applying a tension to the driving medium. The tensioner includes: a compression spring for biasing the driving medium; a stopper for preventing the compression spring from being compressed to a length less than a predetermined length; and an adjustment part for pushing the compression spring to be the predetermined length in a direction toward the driving medium. According to this configuration, the tension of the driving medium is dominant at installation. When the driving medium becomes fatigue to some extent, the stopper of the tensioner becomes off and the compression spring absorbs the vibration of the driving medium. As a result, the exchange timing of the tensioner can be extended by a simple configuration.

Abstract: A sprocket having a slot formed therethrough can be disposed about the non-rotating support rod of a given roller door. This sprocket is then attached to the door-supporting frame such that the sprocket is positioned externally to the roller door. A connector can serve to effect this attachment. This connector might comprise a plurality of bolts with support sleeves. By this approach, the sprocket can be maintained at a fixed distance from the door supporting frame. This connector might also comprise an adjustable connector that adjustably and fixedly connects the sprocket with respect to the door-supporting frame. By one approach, the sprocket connects directly to the door-supporting frame. By another approach, if desired, the sprocket connects to a frame interface which connects, in turn, to the door-supporting frame. This frame interface can itself also have a slot formed therethrough to again facilitate placing the frame interface into an installed position.
