Claims

[Scope of utility model registration request]

In a printer that includes a platen, a carriage that moves along the platen and is equipped with a print head, and a paper feed shaft that provides a transport force to the recording paper installed between the platen and the carriage, the printer is constantly rotating. providing a operative drive gear and an intermediate gear having teeth meshing with the drive gear and intermittent portions of the teeth;
In addition, there is a stopper that stops the intermediate gear at a position where the intermittent part faces the teeth of the drive gear, and when this stopper comes off, the intermediate gear is rotated so that the teeth of the intermediate gear mesh with the teeth of the drive gear. a biasing member to cause the paper feed shaft to move, and the paper feed shaft is provided with a passive gear receiving power from an intermediate gear;
Furthermore, the carriage is provided with a projection for removing a stopper for the intermediate gear. Printer paper feed mechanism.
