Claims

[Scope of utility model registration request]

A platen, a carriage having a long hole on the side of the platen and a circular hole on the opposite side of the platen, a print head mounted on the carriage, and the fixed plate inserted in the long hole of the carriage. ' A first guide rail parallel to the ten, a second guide rail parallel to the platen and movable by being inserted into a circular hole of the carriage, and a second guide rail attached to the platen side of the second guide rail. The second guide rail is provided with a spring that biases the second guide rail in a direction opposite to the platen, and a bendable fixing member that is attached to the opposite side of the second guide rail and on which the ribbon cassette is placed. The head increases the gap between the platen and the print head by the spring when the ribbon cassette is not placed on the fixing member, and increases the gap between the ribbon cassette and the print head when the ribbon cassette is placed on the fixing member. A serial printer characterized in that a gap between the platen and the print head is maintained constant by its own weight.
