A feed mechanism for a photocopy or similar machine directs the media, particularly wide-format media, into a receiving tray along a path which is substantially parallel to, but in the opposite direction of, the original media path. This allows for the removal of media from the front of the photocopy machine. With the drive mechanism in a first configuration, the leading edge of the media is fed directly into the receiving tray. Responsive to a position of the leading edge of the media, the drive mechanism changes to a second configuration so that the subsequent portion of the media is allowed to form a loop and to be delivered to a second receiving area.
In a printer, a unit for turning over a sheet comprises: a conveying roll provided downstream of a printer head; a top roll and a bottom roll which are rotatably coupled to the front end and the rear end of a swingable link, respectively; and at least one elastic endless belt reeved around the top roll and bottom roll, the swingable link being swingable about the axis of the top roll with the top roll into contact with the conveying roll through the endless belt, and a control mechanism for operating the link so that it is swung down for a first half of a period of time for which a sheet passes through the conveying roll and the top roll, and swung up for the second half.
A discharge system for printed media sheets and a printer which utilizes such a discharge system, the discharge system including a tray for the media sheets; rotating transport elements forming a discharge nip for discharging the sheets onto the tray; a guide plate having a surface for guiding the sheets to the discharge nip; and a rotating wheel containing bristles for guiding the sheets towards the discharge nip; the wheel facing said surface of the guide plate. At least one driven transport belt forms one of the transport elements defining the discharge nip, and the guide plate passes in approximately a one-half turn around two pulleys around which the transport belt is passed.
A control unit for operating a valve system in a water conditioner system includes a drive motor having an output shaft coupled to the valve system, a valve position slide switch, an electronic regeneration controller, and a settable mechanical clock. The electronic controller can be programmed by the use of electrical jumpers/dip switches/control knobs. As the drive motor drives the output shaft coupled to the valve system, the drive motor also contemporaneously rotates a dual lead screw in the valve position slide switch. The dual lead screw drives an electrical contactor along a series of electrical contacts in a closed loop fashion. Each of the discrete electrical contacts corresponds to a position of the valve. The electronic controller controls the position of the valve in accordance with dwell times programmed into the electronic controller. If a demand regeneration scheme is desirable, a hardness setting rotary potentiometer can be used to provide analog electrical control.
