Abstract

PURPOSE: To make small the size of the entire carriage, by specifying the construction of the light source unit.
CONSTITUTION: The light source 13 is placed externally at the unit main body side 14 outside of the carriage 12 mounting the photo detection element 8 moved along the guide rod 11, index slit 9, print letter wheel 1, and slit disc plate 3. The light is fed to the carriage 12 with the fiber 15, and the end of the fiber 15 is fixed at the carriage 12 with the fitting fixture 16. Thus, even with the light source 13 greater, it gives no affection on the size of the carriage 12, the entire size of the carriage 12 is made small, and the motor driving the carriage 12 can be of small capacity.
