Abstract

PURPOSE: To stabilize the efficiency of a recording device, etc. which use a laser beam for its light source, by providing a heating member for holding a light emission member which converts an electric signal to an optical signal, at a set temperature or above, so as to obtain a stable optical output by a simple constitution.
CONSTITUTION: On a recording device having a light emission member for converting an electric signal to an optical signal, and a photosensitive member for irradiating the light, a heating member for holding the light emission member at a set temperature of above is provided. For instance, a semiconductor laser chip 11 for emitting a laser beam 12 modulated by a picture signal is held by a mount 14 fixed on a base 21 through a heater 17. Also, a thermistor 16 is installed to the mount 14, and a temperature controlling circuit 28 for supplying a driving current to the heater 17 is accordance with a temperature detected by said thermistor is provided so as to hold the mount 14 at a set temperature or above. In this way, a variation of wavelength of a laser beam is reduced, and an optical output is stabilizied.
