Abstract

Temperature is detected by a temperature sensor disposed near a recording head. When the detection result is a temperature that is higher than room temperature, an appropriate movement amount of the recording head is calculated from a relation between response speed of the temperature sensor and a LED light amount, and a moving speed of the recording head is controlled. When the result of the detection by the temperature sensor is a temperature that is lower than room temperature, an appropriate exposure amount is calculated from the relation between the response speed of the temperature sensor and the LED light amount, and the amount of light emitted by LEDs is controlled.

Claims (21)

1. A printer device comprising:

a recording head including a light source for irradiating a photosensitive material with light and a shutter disposed between the light source and the photosensitive material for controlling irradiation of the light with respect to the photosensitive material on the basis of image data representing an image;

a moving section for relatively moving the recording head and the photosensitive material;

a detection section for detecting a temperature of the shutter; and

a control section for controlling at least one of an amount of light irradiated by the light source and a movement amount by the moving section on the basis of the detection result of the detection section;

wherein the control section controls the amount of light irradiated by the light source when the detection result of the detection section is smaller than a predetermined range and controls the movement amount by the moving section when the detection result of the detection section is greater than the predetermined range.

2. The printer device of claim 1 , wherein the control section controls at least one of the light amount and the movement amount on the basis of a relation between the amount of light irradiated by the light source and a response speed of the shutter that is dependent upon temperature.

3. The printer device of claim 1 , wherein the detection section directly detects the temperature of the shutter.

4. The printer device of claim 1 , wherein the detection section indirectly detects the temperature of the shutter.

5. The printer device of claim 4 , wherein the detection section detects a temperature in the vicinity of the shutter.

6. The printer device of claim 4 , wherein the detection section detects a temperature of the recording head.

7. The printer device of claim 4 , wherein the detection section detects a temperature inside the printer device.

8. The printer device of claim 1 , wherein the shutter includes a liquid-crystal shutter.

9. A printer device comprising:

a recording head including a light source for irradiating a photosensitive material with light and a shutter disposed between the light source and the photosensitive material for controlling irradiation of the light with respect to the photosensitive material on the basis of image data representing an image;

a moving section for relatively moving the recording head and the photosensitive material;

a detection section for detecting a temperature in a vicinity of the recording head; and

a control section for controlling at least one of an amount of light irradiated by the light source and a movement amount by the moving section on the basis of the detection result of the detection section;

wherein the control section controls the amount of light irradiated by the light source when the detection result of the detection section is smaller than a predetermined range and controls the movement amount by the moving section when the detection result of the detection section is greater than the predetermined range.

10. The printer device of claim 9 , wherein the control section controls at least one of the light amount and the movement amount on the basis of a relation between the amount of light irradiated by the light source and a response speed of the shutter that is dependent upon temperature.

11. The printer device of claim 9 , wherein the shutter includes a liquid-crystal shutter.
