A piggyback recorder for use in a printer terminal having a first recorder for printing a first set of data on a document, such as a receipt document. The piggyback recorder is detachably mounted piggyback onto the first recorder, thereby providing a second recorder to the terminal for printing a second set of data on the document. The piggyback recorder comprises a piggyback print member which is capable of printing the second set of data, a mounting member for mounting the piggyback print member directly onto a first print member of the first recorder, a piggyback platen, a second mounting member for mounting the piggyback platen directly onto a first platen of the piggyback recorder, and a solenoid for providing relative movement between the piggyback print member and the piggyback platen. After the piggyback recorder is mounted on the first recorder, the controller can energize the solenoid to cause the piggyback platen to impact the piggyback print member, thereby effecting the printing of the second set of data on the document when the document is located in a printing position between the piggyback print member and piggyback platen.

A ribbon is driven past the printing station of a printer only when the print head is moved in the right-to-left direction across the printer. An endless timing belt causes rotation of a gear pulley that is in mesh with an idler gear. The idler gear is supported on a pair of projecting fingers of a plate that is swingable on the center of the gear pulley. The idler gear is responsive to the direction of rotation of the gear pulley through a drag effect of the projecting fingers with the bottom surface of the idler gear.

The motor mounting bracket is of one piece construction and includes an enclosure formed to contain the mounting flange of the motor and to substantially enclose the motor. The bracket has oppositely positioned spring-like lugs with tips for receiving and securing the mounting flange, and the mounting bracket has a pair of pilot studs matching apertures in the mounting flange for securing the motor flange against movement. The mounting bracket enables a motor to be secured without use of separate screws, bolts, nuts and like parts.
