Abstract

An image formation apparatus comprises an optical flat including: a cabinet; and a scanning optical system containing a light deflection section, the scanning optical system being housed inside the cabinet, so as to emit light scanned by the light deflection section and form an image by the scanned light, wherein the image formation apparatus further comprises a heating section being placed on an outer side of the cabinet to heat the optical flat.

Claims (8)

1. An image formation apparatus which comprises an optical flat including: a cabinet; and a scanning optical system containing a light deflection section, the scanning optical system being housed inside the cabinet, so as to emit light scanned by the light deflection section and form an image by the scanned light; a light emission section that emits scan light from the scanning optical system to an outside of the cabinet; and a shutter by which the light emission section can be opened and closed;

wherein the image formation apparatus further comprises a heating section being placed on an outer side of the cabinet to heat the optical flat;

a temperature sensor that measures the temperature in the cabinet; and

a control section that operates the shutter to be closed when a temperature detection value of the temperature sensor is equal to or less than a first temperature and operates the shutter to be opened when the temperature detection value is equal to or more than a second temperature, the second temperature being equal to or more than the first temperature.

2. An image formation apparatus which comprises an optical flat including: a cabinet; a scanning optical system containing a light deflection section, the scanning optical system being housed inside the cabinet, so as to emit light scanned by the light deflection section and form an image by the scanned light; a light emission section that emits scan light from the scanning optical system; and a shutter;

wherein the image formation apparatus further comprises a heating section being placed on an outer side of the cabinet to heat the optical flat;

a temperature sensor; and

a control section that operates the shutter to be closed when a temperature detection value of the temperature sensor is equal to or less than a first temperature and operates the shutter to be opened when the temperature detection value is equal to or more than a second temperature, the second temperature being equal to or more than the first temperature.
