An image sensor head having a CCD is rotatably attached to a card body having a computer interface. A DC/DC converter for supplying the image sensor head with electric power is provided so as to be situated outside and external device, such as a computer, when the card body is loaded in the external device. This facilitates the radiation of heat. A shielding case is provided to cover and shield the DC/DC converter. When the card body experiences deformation, the shielding case contacts a metal cover which covers a main board within the card body, thereby preventing excessive bending and assuring electrical safety. Thus, in a card-type image sensor of the type which introduces an image to a computer or the like, the power supply for image sensing purposes radiates heat more effectively and is provided with improved shielding.
