    Patent number: 6585542
    Abstract: A connector 11 for a memory card includes a housing 12, a plate 14, a guide plate 16, a lock mechanism 18, and a connector pin keeping part 20. When a memory card 24 is inserted in the full-lock position, a connector pin 28 of the memory card 24 contacts a contacting part 40d of a connector pin 40 so as to press the contacting part 40d of the connector pin 40 downward. Thus, a reading and writing of data available a loading operation of the memory card 24. At this time, after a lock member 56 of the lock mechanism 18 moved in the inserting direction while fitting in the concavity 32 of the memory card 24, the memory card 24 is prevented from being pulled out since the lock member 56 of the lock mechanism 18 is restricted from the moving in the lock releasing direction by a restriction part 14o of the plate 14.

  • Ink jet printer head
    Patent number: 6572217
    Abstract: The present invention provides a plate-like protect member at a front surface of an ink jet printer head having an orifice which is capable of jetting ink. The protect member provides a step around the orifice having an outer portion higher than an inner portion. The protect member also provides an ink repellency layer on an outer portion of the step. Thus, the ink jet printer head of the present invention can prevent the jetted ink from the orifice to creep up toward back of the ink jet printer head which is reverse direction to the ink jetting direction.
