    摘要： In order to enable tapping to be performed precisely and with an appropriate machining time irrespective of the diameter of a tapping tool, a configuration of the present invention includes: a program analysis unit (12) that analyzes a loaded machining program and extracts thread-related information in tapping; a gradient determination unit (14) that determines acceleration regarding movement velocity of the main spindle or the feed shaft on the basis of the thread-related information obtained by the program analysis unit (12); and an interpolation and acceleration/deceleration processing unit (13) that generates a movement command for the main spindle and the feed shaft using the acceleration determined by the gradient determination unit (14). In addition, the gradient determination unit (14) varies the acceleration during acceleration/deceleration of the main spindle or the feed shaft in accordance with the diameter of a tapping tool.

    摘要： A card connector (1) includes a housing (10) having a card insertion opening at its front end into which a card (3) is inserted in a card insertion/removal direction and a metallic cover (30) for covering top and side faces of the housing (10). The housing has a pair of side walls (12a, 12b) extending in the card insertion/removal direction. The cover (30) has a protective member (70, 71) at the card insertion opening for protecting at least a portion of a front end of at least one of the side walls (12a, 12b).
