Claims

[Scope of utility model registration request]

a support base that is guided by a guide rod to reciprocate; a crimping position that is guided by the guide rod and can reciprocate together with the support base; and a crimping position that is crimped to a platen device for printing; A print head having an abutment portion formed on the lower side, which is pivotable between a crimping release position, and a print head having each end of a print ribbon that cooperates with the print head to perform printing is wrapped and fixed.
Printing is carried out by having a pair of built-in reels, which are supported on the support base, and a pair of reel drive shafts provided on the support base are fitted to each of the reels, and one of the reel drive shafts is rotationally driven. A serial printer having a cassette for winding and feeding a ribbon, wherein a first gear device rotatably provided on the support base is pivotally attached to a shaft of the second gear device. The pinion device is engaged with a pair of pinion devices that are rotatably supported by a rocking plate, and when the rocking plate swings in one direction or the other, it engages with a pair of pinion devices that One of the gears selectively engages with and drives one of the gear devices integrally formed with the pair of reel drive shafts, and drives the reel supported by the gear device to feed the printing ribbon. The first gear device is further configured to be engageable with a rack of a rack device that is guided and supported on a guide table of the printer, so that the first gear device can be engaged with a rack of a rack device that is guided and supported on a guide table of the printer, so that the first gear device can be engaged with a rack of a rack device that is guided and supported on a guide table of the printer, so that the first gear device can be engaged with a rack of a rack device that is guided and supported on a guide table of the printer. The rocking plate is rocked according to the direction of movement, and the pinion device on the side in the rocking direction engages with the gear device of the corresponding reel drive shaft to drive the reel drive shaft, thereby moving the support base. The rack device is configured to feed the printing ribbon in a direction opposite to the direction in which the printing ribbon is held stationary relative to the printing paper, and the rack device further includes a rack device arranged opposite to the abutting portion of the print head. and a long groove pin guide that guides the former obliquely in the direction of the reciprocating movement of the support base and in the direction of sunlight, between the rack device and the guide base. a device is provided, wherein - when said rack device is driven in the direction of movement of the support platform by actuation of a solenoid device coupled to said rack device, said slotted pin guide device causes the shifting and shifting device to simultaneously operate at 7; It is also moved in a direction perpendicular to the direction of movement of the support base, thereby pushing the abutting portion of the print head by the abutment edge and pivoting the print head to the decrimping position and causing the first gear device to pivot. Print head pressure release in a serial printer, characterized in that the rack device is disengaged from the rack to release the drive of the reel drive shaft and synchronously stop feeding of the print ribbon. and a printing ribbon unwinding device. −□
