Patent number: 6089450Abstract: A printer and method for negotiating transactions at the point of sale in retail establishments. The POS printer includes a check feeding mechanism that feeds a check into receipt printer with a face-up orientation. The mechanism includes a magnet to magnetize magnetic characters on a check and a read head to read and analyze the signal waveform from each character. The check is pressed up against the read head and the MICR is read only after the printing carriage of the receipt printer has moved to a position outside the print zone, within the printer housing. In this position, a tab, riding on the printing carriage, releases a spring-biased pivot plug. The pivot plug becomes free to pivot, thus releasing a spring-biased plunger, the face of which, in turn, forces the check and its indicia against the read head.Type: GrantFiled: October 6, 1997Date of Patent: July 18, 2000Assignee: Axiohm Transaction Solutions, Inc.Inventor: Jeffrey Koeple

Patent number: 5393152Abstract: A print head is supported on an upper frame of a printing device and a platen and a feeding device are supported on a lower frame. Further, a circuit substrate, a print head moving motor, and a feeding device driving motor are also supported on the upper frame. The upper and the lower frame are connected by a connection member around a rotating axis which is substantially orthogonal to the feeding direction of the print medium. The rotating axis is near a side of the platen in order to easily open and shut the upper frame. When a lock arm is released, the upper frame is pushed up by only a small angle through operation of a pre-open lever and is held in a pre-open position. When upper frame is further opened in an opening direction, the upper frame is held in a fully open position by the operation of an open lock lever. When in the fully open state, the exchange of print paper and/or the removal of the jammed paper can be done easily and safely.Type: GrantFiled: August 19, 1993Date of Patent: February 28, 1995Assignee: Brother Kogyo Kabushiki KaishaInventors: Yoshiteru Hattori, Kazuya Asano, Susumu Misu

Patent number: 5008684Abstract: In a thermal printer, a driving apparatus moves a thermal head both longitudinally of and perpendicularly toward and away from a platen. A racing or idle rotating of gears is utilized in a driving mechanism for reciprocatingly moving a carriage carrying the head. Further, sector gears are used in a loading mechanism for moving the head toward and away from the platen. By combining these two unique structures, the rotational force of a drive motor is converted into the driving force to move the head toward and away from the platen when the carriage is switched between its forward movement and its backward movement. The result is that the carriage driving mechanism and the head load mechanism are operated by the common drive motor.Type: GrantFiled: April 9, 1990Date of Patent: April 16, 1991Assignee: Citizen Watch Co., Ltd.Inventor: Hiroshi Kurafuji

Patent number: 4883375Abstract: A guide shaft guides a print head, which moves along a print line of a platen to perform a printing operation. A rotating member and an eccentric cam member, having a toothed sector portion on its periphery, are mounted on the guide shaft. The guide shaft is guided on a frame by a bearing slot, so as to be movable toward and away from the platen. The eccentric cam member rotates as it is always spring-urged to engage a fixed engaging pin. As a result, the guide shaft moves in a direction transverse to its axis, thus changing a gap between the print head and the platen. As the eccentric cam member rotates in one direction, the print head moves away from the platen, in a retreat stroke. In a rear half of the retreat stroke, the toothed sector portion of the rotating member engages a toothed arm, which is connected to a paper bail member for holding a printing medium down on the platen.Type: GrantFiled: April 12, 1989Date of Patent: November 28, 1989Assignee: Brother Kogyo Kabushiki KaishaInventors: Yoshiyuki Karube, Yuji Kawahara

Patent number: 4642656Abstract: A thermal printer automatically varies torque of a slip clutch provided between a motor and an ink film takeup roller with movements of a thermal head such that the torque transmitted to the takeup roller is smaller when the thermal head is in a transfer position than when the thermal head is in a non-transfer position. This assures that the takeup roller is driven properly by increasing the torque transmitted to the takeup roller when the thermal head is in the non-transfer position and an ink film is taken up in a large amount. When the thermal head is in the transfer position and the ink film is taken up in a small amount, the torque transmitted to the takeup roller is reduced to avoid a great tension acting on the ink film.Type: GrantFiled: December 27, 1985Date of Patent: February 10, 1987Assignee: Minolta Camera Kabushiki KaishaInventors: Kouji Shibuya, Chiharu Imazeki
