## Abstract

Provided is a photo printer including: a base adapted to accommodate paper therein; a pickup roller protruding from the bottom of the base to feed the paper accommodated in the base forwardly; a platen roller disposed in front of the base to discharge the paper fed by the pickup roller forwardly; a head located above the platen roller to apply given heat to the paper; a swing bracket having a mounting portion formed at the front side thereof in such a manner as to be coupled to the head and coupling portions formed at the rear side thereof in such a manner as to be rotatably coupled to the base to allow the head to swing; and pressurizing means adapted to pressurize the head downwardly to allow the head to come into close contact with the paper advancing into the space between the head and the platen roller.

## Claims

### Claim 1

A photo printer for applying given heat to paper responding to the given heat to express colors so as to print images or texts, the photo printer comprising:
a base adapted to accommodate the paper therein;
a pickup roller protruding from the bottom of the base to feed the paper accommodated in the base forwardly;
a platen roller disposed in front of the pickup roller to discharge the paper fed by the pickup roller forwardly;
a head located above the platen roller to apply the given heat to the paper;
a swing bracket having a mounting portion formed at the front side thereof in such a manner as to be coupled to the head and coupling portions formed at the rear side thereof in such a manner as to be rotatably coupled to the base to allow the head to swing; and
pressurizing means adapted to pressurize the head downwardly to allow the head to come into close contact with the paper advancing into the space between the head and the platen roller.

### Claim 2 (depends on 1)

The photo printer according to claim 1, wherein the pressurizing means comprises:
a pressurizing bracket having a pressurizing portion formed at the front side thereof in such a manner as to be located above the head and coupling portions formed at the rear side thereof in such a manner as to be rotatably coupled to the base; and
elastic members adapted to pull the pressurizing portion downwardly.

### Claim 3 (depends on 2)

The photo printer according to claim 2, wherein the pressurizing portion has a pressurizing protrusion formed protrudingly from the underside thereof.

### Claim 4 (depends on 1)

The photo printer according to claim 1, wherein between the head and the platen roller are formed stoppers adapted to prevent the head from moving downwardly under a given position so that the space between the head and the platen roller is formed.

### Claim 5 (depends on 1)

The photo printer according to claim 1, wherein the head comprises a PCB disposed in parallel with the base and adapted to control heating temperature or time thereof, and the base comprises a guide portion inclined forwardly and upwardly from the front end thereof.

### Claim 6 (depends on 5)

The photo printer according to claim 5, wherein between the PCB and the base is disposed a guide sheet adapted to prevent the paper from coming into contact with the PCB.
