Abstract

PURPOSE: To reduce the electric power consumption of a type selecting mechanism for a small printer by providing a cam unit at a type wheel pawl to thereby enhance the space efficiency of the type wheel and reduce the size thereof.
CONSTITUTION: A selective pawl 10 is so provided as not to lock with the lug 9 of a type wheel 4. A cam unit 53 is provided at the type wheel pawl 5. Thus, the pawl 10 can be disposed on the same plane as the lug 9 to thereby largely reduce the thickness of the type wheel 4. The cam unit 53 of the type wheel pawl 5 has a function to rise smoothly the detent spring 8 on the lug 8 to roughen the spring shape so as to enhance the space efficiency of the radial type wheel 4. In addition, the attracting distance between the disk 12, iron core 13 and a yoke 15 is short to thereby reduce the magnetic loss so as to obtain large attracting force with low electric power consumption. The stroke rotates the disk 12 by the drive force of the motor or the like.
