Description

Ribbon cartridge movably

Technical field

The utility model relates to the enlargement of color photos machine, refers to that especially employed ribbon cartridge is movably in the printing frame of the enlargement of color photos machine back of the body, and colour band can be increased the service life.

Background technology

Back of the body printing frame is meant the technical data of printing various expansion sheets at the back side of printing paper, the applicant plays the back of the body printing frame of machine at the coloured silk of patent No. ZL01245607.1, solved the back of the body printing frame problem of domestic enlargement of color photos machine, but the print needle of printhead is when printing, its colour band is short serviceable life, has increased use cost.

Summary of the invention

The purpose of this utility model is to provide movably ribbon cartridge of a kind of enlargement of color photos machine back of the body printing frame, makes colour band improve serviceable life.

For reaching above-mentioned purpose, movably ribbon cartridge of the present utility model, it is complementary design to the back of the body printing frame of the enlargement of color photos machine of patent No. ZL01245607.1, comprise back of the body printing frame and ribbon cartridge, wherein, back of the body printing frame, the one side is equipped with motor, pin joint one colour band rotating shaft on motor output shaft, its top is equipped with the amesiality printhead and the countervane at top, and a screw is arranged below printhead; One colour band location-plate is installed between back of the body printing frame and the ribbon cartridge, and its shape and ribbon cartridge coupling have a recess in the middle of the top, in the recess both sides one pin-and-hole are arranged respectively, and a perforation is respectively arranged at recess below and bottom; One ribbon cartridge, a pin respectively is equipped with in its intermediate recesses both sides, top, and pin penetrates location in the pin-and-hole on the colour band location-plate, and the colour band location-plate is fixed on the back back side of ribbon cartridge, and with gib screw ribbon cartridge and colour band location-plate and back of the body printing frame being spirally connected tightens up.

Superior effect of the present utility model is: the print needle of printhead is that deflection is installed in an outer side in the back of the body printing frame, when the ribbon cartridge of colour band location-plate is housed, when printing, the workplace of its print needle is in the inboard of colour band, ribbon cartridge after removing the colour band location-plate, the workplace of its print needle is in the outside of colour band, the workplace that makes colour band like this is by two workplaces of the reverse side in the front of original inboard and the outside, increase to inboard tow sides and double-edged four workplaces in the outside, improved the serviceable life of colour band widely, reduce user's replacing frequency, made things convenient for the user, reduced cost.
