Claims

[Scope of utility model registration request]

A carriage feeding device in which a locking element of a carriage carrying a small amount of magnetic material for writing and reading is engaged with a screw shaft, and the carriage is linearly fed at a predetermined pitch by rotation of the screw shaft. One spiral groove is formed on the outer circumference of the shaft, which is composed of a plurality of lead resting grooves having an advance angle of approximately 0°, and a blade closing groove that successively connects these lead resting grooves shifted in the axial direction, A carriage feeding device, characterized in that the spiral groove is engaged with a pyramidal tip provided on the retainer, and the width of the lead groove portion is formed to be larger than the width of the lead resting groove portion.
