Claims

[Scope of utility model registration request]

to a shift plate which is reciprocated by a suitable drive;
The bowl is provided with a bowl that engages with the ratchet of the platen shaft when a rotational force is applied by a spring, and the latch part engages with the ratchet when a rotational return force is applied to a separately provided support plate by a spring. The ratchet is prevented from reversing by the spring 1. a detent lever that interferes with the latch and rotates the latch so that its pawl is removed from the ratchet; and an interference part that is rotatably attached and rotated in the release direction. This printer paper feeding device is provided with a release lever that interferes with a detent lever and reverses the rotational return force of the detent lever.
