摘要:
An apparatus for inverting and returning sheets from a printer (1) for large-sized paper comprises an inlet area (11) where the sheet is received from the printer (1), and an outlet area (12) where said sheet is returned to the printer (1). The apparatus comprises a frame (16) mountable on the support of the printer (1), and a guiding slit (18) in the inlet area, said guiding slit being defined by an upper wall (13) and a lower wall (17), where the lower wall (17) extends from the inlet (11) to a clamping slit (22) between a first pair of roller means (23, 24) for receiving and temporarily retaining the front edge of a sheet when seen in the advancing direction, said sheet being received through the inlet area. The lower guiding wall (17) is tiltable and adapted to be moved about a substantially horizontal axis from a sheet-supporting position to a downward sheet-releasing position. The frame (16) carries furthermore a second pair of roller means (33, 24) adapted to received the sheet from the first pair of roller means (23, 24) and to guide the sheet through the outlet area (12) and back to the printer (1).

An air shot or priming mechanism for an injection pen. The injection pen comprises a cartridge-holder and a housing. The cartridge-holder interacts with a nut-member capable of driving the piston rod forward when relatively rotated. The cartridge-holder is rotational coupled to the housing such that rotation of the cartridge-holder relatively to the housing causes the nut-member and the piston rod to rotate relatively, thus the relative angular rotation between the cartridge-holder and the housing determines the size of the air shot so performed.

The invention concerns an injection device for apportioning set doses of a drug from a reservoir to a subject. The injection device comprises a dose setting member (20, 70) which is screwed out from the housing (30) to set a dose and pushed axially back to the housing (30) in order to expel the set dose. A scale drum (80) is axially and inrotatable coupled to the dose setting member (20, 70) such that the scale drum (80) is rotated up a thread (34) when the dose setting member (20, 70) is rotated to set a dose. When the dose setting member (20, 70) is pushed axially back to its initial position to inject the set dose, the scale drum (80) is released from its inrotatable connection in order to allow the scale drum (80) to rotate down the thread (34) and back to its zero position.

An apparatus for receiving, inverting and returning sheets from and to a printer for large-sized paper, said printer being adapted to be automatically fed a web of paper from a supply of paper through an inlet (6), defined by a portion of a paper-supporting plate (7), where said printer further is adapted to print and cut sheets of said web of paper and to guide the printed sheet out thereof through a separate outlet (13), where the apparatus is adapted to receive the just printed and cut sheets from said outlet and to return said sheets to the printer in the inverted state. The apparatus comprises a rotatable first guide means (14), which in one position guides the sheet into the apparatus and in a second position guides said sheet past the apparatus. The apparatus comprises furthermore a first driving roller means (36) and a second guide means (21) pivotally arranged relative to said roller means, where the second guide means (21) in a first position guides the sheet advanced to the apparatus round the first roller means (36) during the initial movement of the sheet into the apparatus, and where said second guide means (21) in a second position presses said sheet into a driving engagement with the first driving roller means (36) in such a manner that said first driving roller means (36) takes over the driving of the sheet both during the remaining movement of said sheet inside the apparatus as well as during the movement of said sheet out of said apparatus again and into the printer through the inlet (7) of said printer while the direction of rotation is inverted. The apparatus comprises also a second driving roller means (46) adapted to engage the portion of the web of paper (60) being left on the paper-supporting plate (7) after the sheet has been cut off and to pull said portion temporarily backwards in such a manner towards the paper supply (61) while the sheet is being inverted that said sheet can be guided into the printer without colliding with the web of paper.
