Abstract: A heating head which functions as an erase head for quick operation can be turned off while not in use yet it can turn on when it is used (on-demand operation) and operates stably without over-heating even for the long operation, re-writable media record erasing equipment and erasing method. At least one strip of Heating Resistive Element is formed on one side (surface) of Head Substrate lengthwise. The Temperature Measurement Resistive Element is formed on the same side of the Head Substrate surface. The other side is facing the Heat Sink to hold the Head Substrate and the Thermal Resistive Layer is sandwiched. When the re-writable media record is erased, the media is moved across the erase head after the temperature of the temperature measurement resistive element reaches the predetermined level.

Abstract: A printer including a light emitting body for emitting light along a main scanning direction. A photosensitive surface of a photosensitive body is sensitized by the light emitted from the light emitting body. The photosensitive surface is moved relative to the light emitting body at a predetermined distance along a sub scanning direction perpendicular to the main scanning direction. While the photosensitive surface is moved at the predetermined distance along the sub scanning direction, the light emitting body emits the lights at a predetermined period. The predetermined period is determined to be a time required for moving the photosensitive surface at a dimension of the light emitting body along the sub scanning direction.

Abstract: A control circuit for outputting a signal for controlling an amount of light emitted from a plurality of light emitting elements. The control circuit includes a controller or CPU, and a D/A converter outputting a signal for setting a voltage in multiple gradation in accordance with a lighting state of the light emitting element. An amplifying circuit amplifies an output of the D/A converter and outputs an amplified output as a control signal. A reference voltage generating circuit generates a reference voltage and a comparator compares the control signal with the reference voltage. The controller varies an output of the D/A converter based on the result of comparison by the comparator, to adjust the output of the D/A converter so that the control signal is equivalent to the reference voltage. Accordingly each voltage is reset in the multiple gradation to allow the light emitting element to appropriately emit light based on the adjusted output.
