A device for printing flat packages fed individually to a printing unit of a franking machine, pass the printing unit on one side and are guided on a side edge in the conveying direction, including a conveying apparatus which grips the packages at a front end and, by a guide plate forms a conveying plane of a conveying gap with an opposite conveying unit of the conveying apparatus. In the conveying direction, the conveying unit has two endless drawing devices next to each other which circulate a common axle on deflecting rollers, and the upper run of which, and the lower run of which are guided on running rollers mounted freely rotatably in pairs so as to lie opposite one another at pivotable ends of double lever arms assigned to the upper and the lower run, and supported on the inner side of the runs by spring force.

A belt feeding device includes an endless belt, stretching rollers including a tension roller, a bearing member supporting the tension roller, a beating support member supporting the bearing member, an urging member urging the tension roller, a supporting member supporting the bearing supporting member, and a locking member. The locking member is movable between a first position where an engagement between the locking member and one of the bearing support member and the bearing member is released and the bearing member is permitted to move so as to apply the tension to the belt, and a second position where the locking member locks the bearing member by engaging with the bearing support member and the bearing member and the bearing member is restricted to move. The bearing member, the bearing support member, the urging member, and the locking member constitute a unit to be integrally dismountable from the supporting in the second position.

A device includes a head to perform an operation on a conveyed object; a head moving device to move the head in a width direction orthogonal to a conveyance direction of the conveyed object; a position detector to detect a position of the conveyed object in the width direction; a speed detector to detect a moving speed of the conveyed object in the width direction; a position predictor to obtain a predicted width position of the conveyed object after a predetermined period, based on a detected position of the conveyed object and a detected moving speed of the conveyed object; a speed calculator to calculate a travel speed of the head; and a head travel controller to control the head moving device to move the head at the calculated travel speed. With the calculated travel speed, the head arrives at the predicted width position after the predetermined period.

A belt drive includes a belt and at least one pair of spaced apart rails extending in a first direction and defining a gap. The belt is aligned with the gap and to be driven in an endless loop with the belt including a first movable portion external to the gap on a first side of the rails and a second movable portion biased to be recessed within the gap on an opposite second side of the rails. A rewritable display medium is releasably engageable in a sandwiched position between a slidable contact surface of the rails and a first segment of the second movable portion external to the gap to move the display medium in the first direction for contact-less imaging via a unit spaced from the rails.

An inadvertent swing of a steering roller is restricted with a versatile configuration. A belt conveying device includes a belt member configured to be stretched around a steering roller and a roller member, and a movement mechanism configured to move the roller member. The roller member is movable to a first position and a second position where the roller member is moved further inward on an inner peripheral side of the belt member than the first position by the movement mechanism. In the movement mechanism, a restriction portion capable of restricting a swinging range of the steering roller more in a case where the roller member is at the second position than in a case where the roller member is at the first position is provided.

A conveyance device includes a conveyor to convey a conveyed object, a head unit to perform an operation on the conveyed object, a sensor to obtain surface data of the conveyed object, provided for each head unit, and at least one processor. The processor is configured to calculate a first detection result including at least one of a position, a speed of movement, and an amount of movement of the conveyed object based on the surface data, set a detection area based on the first detection result, calculate a second detection result using the detection area according to the first detection result. The processor is further configured to control operation of the at least one head unit based on the second detection result.

A glass sheet processing apparatus includes a glass sheet processing station including a laser cutting assembly that includes an optical arrangement positioned in a beam path of the laser providing a laser beam focal line that is formed on a beam output side of the optical arrangement. A glass holding conveyor belt carries a glass sheet by the laser cutting assembly so that the laser beam focal line is positioned on the glass sheet with the glass sheet on the glass holding conveyor belt. The glass holding conveyor belt is configured to carry multiple glass sheets to the laser cutting assembly for cutting the multiple glass sheets on the glass holding conveyor belt in a repeated fashion.

A transporting device includes a first belt, a second belt that transports a medium in cooperation with the first belt, a first shifting member that shifts the first belt in a width direction of the first belt, a second shifting member that shifts the second belt in a width direction of the second belt, a rotatable member that is rotatable around its own axis, and a forming member provided across the first belt and the second belt from the rotatable member and that forms a nip between the first and second belts in cooperation with the rotatable member. The rotatable member and the forming member cooperate to form the nip at a pressure ratio lower than about 1. The pressure ratio is obtained by dividing a pressure applied to each of two axial ends of the rotatable member by a pressure applied to an axial center of the rotatable member.

A paper transfer device includes a paper transfer unit that transfers a paper laid on a transfer surface beneath an inkjet head, a downstream-side transfer portion that is disposed on a downstream side of the transfer unit along a transfer direction of the paper and transfers the paper along a downstream-side transfer path extending downward from the transfer surface, a paper leading portion that leads the paper from the transfer unit to the downstream-side transfer portion, and a controller that controls the paper leading portion to press the paper after a leading end of the paper is led to the downstream-side transfer portion by the paper leading portion.

A sheet feeder comprises a feed deck for supporting a stack of sheets (65) to be fed. The feed deck may be formed by a bed of freely spinning rollers. A feed block (62) comprises a friction pad (66) that projects from the bottom of the feed block (62) towards a drive belt (42) to define a gate therebetween. The drive belt (42) frictionally engages the underside of a bottom sheet of the stack (65) and urges the sheet towards the gate. The feed block (62) comprises a front face (72) immediately upstream from the gate, which is inclined at a sharp angle to the feed direction. The friction pad (66) comprises a lower face that is substantially parallel to the feed direction and does not intersect the plane of the feed block front face (72).
