PURPOSE:To make it possible to use another program only by depressing operation by providing the home work station device with an auxiliary storage device storing part for ejecting the other auxiliary storage device by the loading force of one auxiliary storage device and turning on a reset switch. CONSTITUTION:If an IC card 2b is inserted when a user intends to use the program of the IC card 2b, a cam 9 is rotated, an IC card 2a is simultaneously ejected, a reset switch is depressed and the program of the IC card 2b is read out to execute the program. Since a connecting plate 37a is arranged on a position shifted from a connecting plate spring 31a, a data bus writing is not connected to the ejected IC card 2a similarly to the ejection of the IC card 2b, but a power supply wiring is connected to the IC card 2a, so that an application program can be switched without destructing a semiconductor memory 21a in the IC card 2a.
