The wheel (32) has a raceway (45) along the periphery thereof for guiding a saw wire (3) of the wire saw (1). The pivot bearing (42) is coaxially inserted in the wheel (32). An outer sleeve (51) protrudes from a lateral surface (49) of the wheel (32). An inner sleeve (50) protrudes from a lateral surface opposite the one lateral surface (49). A radius (53) of the inner sleeve (50) is smaller than a radius (52) of the outer sleeve (51). The sealing element (55) is placed on the outer sleeve (51) or inserted into the inner sleeve (50).

A sheet conveyor includes: a chute which has openings spaced apart from each other in a first direction and guides a sheet; a drive shaft; drive rollers mounted on the drive shaft and each partly protruding from the chute through a corresponding one of the openings; driven rollers each urged and contactable with a corresponding one of the drive rollers; an intermediate bearing disposed at a first position located between adjacent two of the drive rollers; and a holder provided on the chute to hold the intermediate bearing located at the first position. The intermediate bearing is in contact with an outer circumferential surface of the drive shaft when located at a second position different from the first position. The intermediate bearing is slid from the second position to the first position in the first direction and held by the holder at the first position.

A sheet feeding device includes a pickup roller, a feed roller, a feed holder and a mounting part. The pickup roller rotates around a first rotating shaft and then to feed a sheet. The feed holder supports the first rotating shaft. To the mounting part, the feed holder is mounted and dismounted. The mounting part has a pair of guide grooves. The feed holder has a pair of guide shafts protruding in a direction parallel to the first rotating shaft. The pair of guide shafts are guided along the pair of guide grooves. The pair of guide shafts are formed on an axis line different from an axis line of the first rotating shaft.

In a print apparatus including a first holder unit that holds a rolled medium, the first holder unit includes a base, a main shaft that is supported on the base and moves along an axial direction to thereby fix the rolled medium, a split-nut portion that is provided on the base and is splittable into two, a bolt that moves the main shaft along the axial direction, a handle that rotates the bolt, and an opening/closing mechanism that opens and closes the split-nut portion. The split-nut portion is screwed onto the bolt and moves the bolt rotated with the handle along the axial direction while the split-nut portion is closed, and releases the bolt while the split-nut portion is open.

A sheet conveying device includes a casing, first discharge rollers arranged in an axial direction, a roller shaft supporting the first discharge rollers and configured to rotate together with the first discharge rollers, second discharge rollers provided in correspondence with the first discharge rollers, a bearing member attached to the casing such that the bearing member is entirely located between adjacent two of the first discharge rollers, the bearing member supporting roller shaft. The bearing member includes a downstream guide located downstream of the roller shaft in a conveying direction in which the sheet is conveyed. The downstream guide of the bearing member protrudes toward the plurality of second discharge rollers beyond a tangential line at a contact point between one of the first discharge rollers and a corresponding one of the second discharge rollers, when viewed in the axial direction.

A non-driving pulley included in the conveyor device has an adjustment collar between a bearing and a shaft of the non-driving pulley. The adjustment collar has an adjustment outer surface inclined relative to a reference axis X.sub.B of the shaft. The adjustment collar rotated relative to the shaft changes the state of inclination of the adjustment outer surface supporting the bearing, thereby changing the orientation of the non-driving pulley having the wrapped belt.

An object of the present invention is to easily regulate mistracking of a belt revolving between multiple pulleys in a conveyor device. Another object of the present invention is to save the space of a mechanism for regulating mistracking in the conveyor device. A non-driving pulley included in the conveyor device has an adjustment collar between a bearing and a shaft of the non-driving pulley. The adjustment collar has an adjustment outer surface inclined relative to a reference axis X.sub.B of the shaft. The adjustment collar rotated relative to the shaft changes the state of inclination of the adjustment outer surface supporting the bearing, thereby changing the orientation of the non-driving pulley having the wrapped belt.

A sheet feeding device includes a feed roller, a feed holder, a supporting frame and a driving shaft. The feed roller is configured to rotate around a rotating shaft. The feed holder is configured to support the feed roller. The supporting frame has a storage recessed part in which the feed holder is attachable and detachable along a direction crossing an axial direction of the rotating shaft. The driving shaft is supported to the supporting frame on one side of the storage recessed part in the axial direction. The storage recessed part has a guide part and a positioning part. The guide part is configured to guide the feed holder. The rotating shaft is coupled to the driving shaft by sliding the feed holder positioned at the aligning position by the positioning part in the axial direction.

An automated product dispenser for dispensing a product from a supply of product is provided. The automated product dispenser includes a chassis assembly, a drive assembly, and an isolation member. The chassis assembly includes a chassis frame, and the drive assembly includes a motor, a drivetrain, and a drivetrain housing. The isolation member mounts the drive assembly to the chassis assembly such that the drive assembly is substantially spaced apart from the chassis frame. A related method of inhibiting vibration transmission in an automated product dispenser also is provided.

A pipeline-type positive warp yarn feeding device includes a yarn bobbin frame and a yarn feeding frame. The yarn feeding frame is provided with a positive yarn feeding assembly including a positive yarn feeding power component and positive yarn feeding wheels on the yarn feeding frame, the positive yarn feeding wheels correspond to yarn bobbins on the yarn bobbin frame, an outer circumference surface of a wheel shaft of each positive yarn feeding wheel defines spiral yarn feeding grooves, a groove mouth width of each yarn feeding groove is matched with a width of a strand of yarn, the yarn on the yarn bobbins is wound on the positive yarn feeding wheels, each yarn feeding groove accommodates a single strand of the yarn, and the positive yarn feeding power component is configured to drive the positive yarn feeding wheels to rotate and feed the yarn through a transmission gear assembly.
