ABSTRACT:
A recording device enables the tension state of an endless belt type photographic body to be adjusted so as to maintain a proper tension, including adjusting for, changes of belt length caused by the change of temperature and humidity or the change with time of employment surroundings, and also adjusting for the change of belt tension entailed by load variation on operation of the device or eccentricity of the driving roller. The recording device is provided with a driving roller, driven rollers, and the endless belt type photographic body which is wound around the driving roller, and the driven rollers, the driving roller driving the driven rollers. The recording device is also provided with a sensor for detecting the tension of the endless belt type photographic body, and a movement mechanism for moving at least one of the driving roller and the driven rollers based on a detection signal of the sensor.
