Abstract
A media thickness compensating device for a printer which senses the thickness of each record medium, e.g., a printing sheet, mounted on a platen to maintain a proper printing gap between the record medium and a print head. In this device, sensing means including a pressure-sensitive conductive rubber member is disposed so as to be movable toward and away from the platen. The movement of the print head is compensated in accordance with the displacement of the sensing means moved from a reference position to a position where the sensing means comes into contact with the record medium to cause the resistance of the pressure-sensitive conductive rubber member to reach a predetermined reference value. Thus, the printing gap can be kept proper at all times.
