Various embodiments provide a dual purpose press-bar and heat sink for an integrated circuit card (ICC) reader. The dual purpose press-bar and heat sink provides two functions. First, the dual purpose press-bar and heat sink conducts and dissipates internal heat generated by a high data transfer ICC inserted in to the ICC reader. Second, the dual purpose press-bar and heat sink ensures that contact pads of the high data transfer ICC create reliable electrical connections with ICC contacts of the ICC reader. As such, the dual purpose press-bar and heat sink simultaneously dissipates heat from a high data transfer ICC and ensures that a high data transfer ICC maintains proper electrical connections with ICC contacts of an ICC reader.

A card insertion unit is provided, which prevents the mixture of lights in different colors even with light sources to emit lights in different colors at the periphery of a card insertion slot.

According to one embodiment, a reader/writer includes an insertion portion and a support member. An information storage medium held by a person with fingers is inserted into the insertion portion. The support member supports the insertion portion on an installation surface by causing an insertion direction of the information storage medium with respect to the insertion portion to be lowered to the front to intersect with a horizontal plane. In the support member, an intersection angle between the insertion direction and the horizontal plane is set to a predetermined acute angle at which the fingers of the person do not interfere with the installation surface when the information storage medium is inserted into the insertion portion.

An electric apparatus includes a substrate having a ground pattern on a top surface of the substrate; a conductive housing on the ground pattern and having an insertion space; a conductive connector disposed between the ground pattern and the conductive housing and connected to the ground pattern and the conductive housing, wherein the conductive housing is fixed to the substrate via the conductive connector; and a conductive cover coupled to the conductive housing, wherein the conductive cover is configured to move from a first position, at which the conductive cover externally opens the insertion space, to a second position, at which the conductive cover closes the insertion space.
