摘要： A paper feed control system in a printer allows a first type of manual paper feed operation in which a course manual paper feed is conducted while an electrical detent operation is conducted by a paper feed drive pulse motor, and a second type of manual paper feed operation, in which a fine adjustment of the paper position is carried out while the electrical detent operation is precluded. A counter system is associated with the rotation of a paper feed drive pulse motor so as to provide the electrical detent operation at preselected positions. When the second type of manual paper feed operation is completed, the counter system is reset so that the subsequent electrical detent operation is carried out with reference to the finely adjusted paper position.

摘要： A portable radio paging device 2 provides a printout of the messages it receives, it has a dot matrix printer 24 and a photocell 22 sensing perforations for detecting the movement of paper 16 past the printer. The user is warned of the receipt of a message by a bleep and draws the paper from the paging device. The message is printed evenly along the length of the paper despite variations in the speed at which it is pulled, as a result of the photocell and control circuitry 10. A second bleep indicates that the whole message has been printed and the user can then tear off the paper strip to examine the message. The photocell 22 may be replaced by an optical disc driven by one of two idler rollers gripping the paper.

摘要： This invention is a platen knob device in a typewriter for releasing a platen of the typewriter from a platen pitch feed mechanism and changing the platen over to a continuous feed. This platen knob device includes a platen variable fixed onto a platen shaft and a platen driver operative in association with the platen pitch feed mechanism and slidably provided on the platen shaft. The platen driver is urged by the platen variable through a spring, whereby the platen driver and the platen variable are engaged with each other, in which condition, if the platen knob is rotated, then the platen is changed over to the pitch feed. If the platen knob is urged in a direction opposite to the direction in which the platen knob is urged by the spring, then the platen driver is urged against an end face of a cylindrical portion of the platen knob to move in the axial direction thereof and separated from the platen variable to change the platen over to the continuous feed.

摘要： A platen variable apparatus is disclosed for rotatably adjusting a platen in step increments and in fine amounts in a typewriter. The apparatus includes an individual hub member rotatably mounted on a platen extension and having teeth thereon intermeshed with teeth of a flexspline fixed on the platen extension. A coarse adjusting member is fixedly coupled on the platen extension for positively rotating the platen in step increments controlled by a detent. A rotatable fine adjusting wheel has an internal wave generator surface that cooperates with the flexspline for moving the flexspline relative to the hub member which adjusts the platen in fine amounts.

摘要： The present invention is an improved media advancement mechanism for use in combination with a printer that includes a frame, a print head mechanically coupled to the frame and a platen mechanically coupled to the frame so that a print media may pass between it and the print head. The printer also includes a pair of sprockets which are adapted to support the print media and which are mechanically coupled to the frame by a sprocket shaft. The improved media advancement mechanism includes a ratchet wheel which is mechanically coupled to the sprocket shaft in order to provide rotational motion thereto in response to an electrical signal from the printer thereby moving the print media incrementally. The improved media advancement mechanism also includes an adjustment plate pivotally coupled to a sidewall of the frame and a restraining device for restraining the adjustment plate from its pivotal motion. The improved media advancement mechanism further includes a solenoid with an armature which receives an electrical signal from the printer and which is mechanically coupled to and disposed on the surface of the adjustment plate, a pawl which is mechanically coupled to the armature of the solenoid and which is disposed so that it can mechanically engage the teeth of the ratchet wheel in order to impart rotational motion thereto and a spring which mechanically couples the pawl to the adjustment plate.

摘要： There is described a record material feed mechanism for use in an electronic cash register for feeding a record member to a printing station wherein data is printed on print lines located on the record member during the operation of the cash register. The feed mechanism will automatically position each succeeding print line of the record member adjacent the printing station on successive printing operations of the cash register. Included in the feed mechanism are a pair of cam actuated gear segments which control the length of movement of the record member between a home position and a position adjacent the printing station in the cash register. During the feeding of the record member to the printing station, the gear segments are positioned in tandem to move the record member a predetermined length while in a feed-out operation, the segments are positioned in an overlap condition to move the record member a distance which is one print line less than the feed-in movement.
