Abstract: An embroidering machine includes RAM which stores temporally the embroidering data read out from a memory card; a device which detects attaching or detaching of the memory card; a buffer circuit which makes and breaks a power source and buses for the memory card; an indicator or warning device which indicates the circuit making and breaking; a device for double checking the data sent from the memory card to RAM; and a device which indicates to the operator the presence of a required card. In the detector of the memory card, determined detecting edge terminals of the memory card are made shorter, and when the card is detached the circuits of the detecting terminals are disconnected earlier than the remaining circuits. When the circuit of the detecting terminal is disconnected, the port of the circuit is rendered to be high impedance by the buffer circuit and the power source to the memory card is disconnected before the terminal of the power source and the bus of the memory card are disconnected, so that if the memory card is slipped out from the embroidering machine while processing "ACCESS" of the memory card, the memory IC is not destroyed.
