The present disclosure provides a drive transmission apparatus capable of reducing vibration of rotating member. The apparatus includes a shaft, a pin, and a rotating member. The rotating member is engaged with the shaft by the pin and rotates with the shaft. A protruded portion is provided on one of an outer circumferential surface of the shaft and an inner circumferential surface of the rotating member. The rotating member is attached to the shaft with the protruded portion in pressure contact with another one of the outer circumferential surface of the shaft and the inner circumferential surface of the rotating member, so that swinging of the rotating member around the pin is restricted.

A recording apparatus includes: a housing; a recording device that is provided inside the housing; a medium receiving tray moves between a first position and a second position, the first position being housed inside the housing, the second position being a position of protruding from the housing; a guide for guiding the medium receiving tray; and a guided portion of the medium receiving tray being guided by the guide, wherein the guide includes a first guide area and a second guide area, wherein the first guide area is guiding the guided portion from the first position to a third position that is located between the first position and the second position before the second position, wherein the second guide area is guiding the guided portion from the third position to the second position, and wherein the second guide area includes a narrowing area narrower than the first guide area.

A paper feed apparatus includes a paper feeding roller and a separating pad for separating paper one by one and feeding the paper. This separating pad is supported by a separating pad holder to be abutted onto the paper feeding roller with a predetermined pressure. Furthermore, the separating pad holder is provided with a weight member in a loosely-fitted state.

An image-forming apparatus forms an image on a roll sheet. A printer receives the roll sheet, forms the image thereon and ejects the image-formed roll sheet to a reel. A sheet position sensor, which is positioned near the printer, measures a position of the roll sheet along a width direction thereof. A control portion receives positional measurement data about the position of the roll sheet along the width direction thereof from the sheet position sensor and controls at least one of start time of image-forming operation in the printer and an image-writing position of the printer by settling at least one of the start time of image-forming operation and the image-writing position based on the positional measurement data.

A sheet storage device, including a storage tray configured to store a sheet therein; a board, on which the sheet to be stored in the storage tray is placed, the board being configured to be swingably supported by the storage tray at a first position closer to a first end thereof than a second end being opposite from the first end to swing about a swing axis; and a projection configured to protrude from a bottom of the storage tray toward the board, the projection including a contact part being configured to contact the board member at a second position closer to the second end than to the first end of the board, is provided. A length of the contact part along an axial direction of the swing axis is smaller than a length of the board at the second position closer to the second end.

A sheet processing device includes a sheet processing unit that is moved to perform sheet processing on a sheet; a sheet-processing moving unit that moves the sheet processing unit; a drive-mode determining unit that determines a drive mode of the sheet-processing moving unit; and a drive control unit that drives the sheet-processing moving unit in accordance with the drive mode. The drive-mode determining unit determines the drive mode such that the sheet processing unit is moved at combination acceleration that is a combination of first acceleration and second acceleration with a shift of time that is determined based on the cycle of the natural vibration that occurs during acceleration of the sheet processing unit.

The invention relates to a vibration-damping apparatus (18) for a winding device (4) of a textile machine (1), which textile machine produces cross-wound packages (5), the vibration-damping apparatus being provided for reducing the vibrations that occur at the pivotably mounted package cradle (8) during the winding operation of the textile machine (1). According to the invention, in order to obtain a vibration-damping apparatus which is unproblematic both with regard to safety and with regard to contamination and which also always ensures a vibrationally relatively stable state of the package cradle, the vibration damper is in the form of a friction damper (20) having friction forces of different intensity depending on the working direction, the friction forces acting as the cross-wound package (5) lifts off during the winding operation being greater than the friction forces acting during the return of the cross-wound package (5).
