Protrusions (33) are provided on a bottom surface (242) of an electric cell housing (24) in front of a card housing (30) provided to an inner wall (241) of the electric cell housing (24). The dimension (H1) by which the protrusions (33) project out is no greater than the height (H2) from the bottom surface (242) to the lower edge of an insertion/removal opening (31) in the card housing (30). When a card (13) is housed in the card housing (30), the card can be inserted into the insertion/removal opening (31) in the card housing (30) along the protrusions (33) without lifting the front edge of the card (13). The card (13) can therefore be easily housed in the card housing (30). |
