た。<Prior Art> Conventionally, this type of device uses the forward rotation output of a drive motor to move a carriage equipped with a printing member through the printing stroke, and the reverse rotation output to move the carriage in its return stroke and paper feeding operation. It came. However, since the paper is fed in almost the same stroke as the return movement of the carriage, even when the number of digits to be printed is small, the carriage is moved to the maximum printing stroke, and then the paper is fed during the return movement of the carriage. Further, when carrying out continuous paper feeding, a complicated mechanism was required to interrupt power transmission from the drive motor to the carriage.

係なく紙送りができるという効果がある。<Example> FIGS. 1 and 2 show an example of the present invention.
1 is a drive motor attached to the frame, 2 is a motor gear attached to the drive motor, 3 is a drive shaft attached to the frame, 4 is a drive gear that transmits the output of drive motor 1 to drive shaft 3, and 5 is a drive A worm, which is a driving member, is pivotally attached to the shaft 3 for free rotation in the lateral direction, 6 is a rack provided parallel to the printing paper 20 and engages with the worm 5, and 7 is driven to move integrally with the worm 5 in the lateral direction. A carriage is attached to the shaft 3, 8 is a printing member included in the carriage 7, 9 is a platen attached to a frame and feeds paper, and 10 is set to transmit the rotational force of the drive motor 1 to the platen 9 only when the rotation is reversed. 11 is an intermediate gear, and 12 is an elastic member such as a spring provided to press the worm 5 in the direction of arrow A. Next, the operation will be explained. The carriage 7 is in the home position, and the worm 5 and rack 6 are disengaged. Drive motor 1
is energized, and the rotational force of the drive motor 1 is transmitted to the drive shaft 3 via the motor gear 2 and the drive gear 4. A worm 5, which rotates integrally with the drive shaft 3, rotates and engages with the rack 6 under the pressure of an elastic member 12, thereby integrally moving a carriage 7 equipped with a printing member 8 in the direction of arrow A to perform printing. Immediately, the drive motor 1 is reversely energized by the print end signal, and the carriage 7 is
performs a return operation in the direction of arrow B from the print end position to the start position. In addition, drive motor 1 when reversely energized
The rotational force is transmitted to the platen 9 via the motor gear 2, intermediate gear 11, and clutch means 10, and the platen 9 feeds the paper. When the carriage 7 is moved back, the worm 5 and the rack 6 are disengaged and the movement of the carriage 7 is completed when the carriage 7 is returned by a distance corresponding to the number of printed digits and then rotated for a certain amount of time.
Even after the carriage 7 has finished moving, while the platen 9 is still feeding the paper, the drive gear 4, worm 5,
The drive shaft 3 rotates idly. Although the worm 5 and the rack 6 are disengaged, they are constantly pressed in the direction of arrow A by the elastic member 12, so when the drive motor 1 is reversely energized for the next printing process and the drive shaft 3 rotates in the opposite direction, The worm and the latch mesh easily. This structure has the effect that paper can be fed regardless of the number of printed digits.
