A printer paper feed apparatus having a single-form feed function and a continuous-form feed function, in which a pin tractor mechanism for feeding the continuous forms is situated upstream of the platen in terms of paper feed. The apparatus includes a guide plate member for the single forms having a base end pivotally supported in the vicinity of a single-form insertion inlet formed in an upper side of a printer main body, the guide plate member being capable of selectively assuming a horizontally accommodated position and a paper insertion guide position at which it is raised in an inclined attitude, a clutch mechanism provided in a rotating force transmission system between a tractor drive shaft of the pin tractor mechanism and the paper feed motor, and a clutch control mechanism for controlling engagement and disengagement of the clutch means in dependence upon whether the guide plate member is situated at the accommodated position or the single-form insertion guide position. When the guide plate member is situated at the single-form insertion guide position, the clutch mechanism is placed in a state in which the rotating force cannot be transmitted from the paper feed motor to the tractor drive shaft, thereby terminating drive of the pin tractor mechanism.
