[Also in Groups XV and XIX] In a graphic communication device, wherein a stylus is moved by two co-ordinate positioning motors 127, 128, Fig. 1, across a paper web 53 supported on a platen 45, the web is fed to and from the platen by a pair of sprocket drive belts 37, 41, mounted on opposite sides of the platen, and is held in engagement with the belts by a guide 64. The belts are driven by an electric motor 98 through gearing 102, 103, a shaft 27 and sprocket-wheels 31, 32, under the control of a switch 106, Figs. 2, 8 and 9. Depression of a button 121 provides movement of an operating lever 109 which depresses a switch actuating lever 108, closing the switch 106. Rotation of the shaft 27 causes rotation of a cam 113 through gearing 116, 115, Figs. 1 and 8, and after 360 degrees rotation of the cam, a cam follower 112 associated with the lever 109 enters the notch in the cam causing the switch 106 to open. Also, the initial closing of the switch 106 occurs when the motor 127 is actuated to one extreme rotational position, so that a lever 125, Figs. 1 and 9, engages the extension 124 of the switch actuating lever 108. Therefore, upon initially closing the switch 106, the paper feed operation proceeds automatically until the cam follower 112 enters the notch in the cam 113. The guide 64 has two arms 65 and 66 connected by a bridging member 67. Each arm is pivotally mounted on a vertical support member 61, 62, Fig. 1. The crosssection of each arm, Fig. 5, comprises a pair of depending leg elements 72, 73, which are aligned with and are positioned to bear downwardly on the outer edges of the sprocket belt 37. The guide 64 is latched into the working position with a latching mechanism which includes a toggle arm 76 fixed to a shaft 75, Fig. 2. The lower end 77 of the toggle arm extends beyond the shaft 75 and a latching lever 78 is pivotally mounted on the end 77. A spring 85, Fig. 6 (not shown), biases the lever 78 in a direction to bring the dog 81 into engagement with a pin 82 on the guide 64. A spring 93 urges the web 53 against a guide shoot 52, 53, Fig. 2, when the guide 64 is in position. In a modification, Fig. 10 (not shown), the sprocket belt 37 is replaced by a friction belt 137, and a roller 139 is mounted on the forward end of the guide 64 in a position to engage the web immediately over the drive-sprocket 35.
