Abstract: The IC according to this invention has a semiconductor chip which includes a first and a second pad lines consisting of a plurality of pads connected respectively to the corresponding plurality of terminals on two sides of a package corresponding to two sides of a mutually opposing first and second sides on a semiconductor substrate, a first and a second internal circuits formed respectively closer to the corresponding pad line in the space between the first and the second pad lines, for applying a predetermined processing to a transmitted data, a first and a second data bus connected respectively to these internal circuits for carrying out transmission of data for the corresponding internal circuit in bit parallel fashion, and wirings which connect these data bus to the plurality of pads.Since this arrangement enables one to make the wiring length between each pad and the corresponding data pad uniform and short, the IC device according to this invention can reduce the transmission time of the data.

Abstract: When a microfiche is automatically retrieved by a microfiche retrieval device, and the data of a target frame is input from the keyboard, the microfiche is conveyed to automatically retrieve the frame at the position relevant to the input data, and the largest frame is projected on a reader screen. The positional data for retrieving frames corresponding to the frame addresses other than that of the target frame and the fiche-mode data necessary for retrieving and outputting the imaged frames is stored in memory prior to retrieval of a frame. The stored data is read out so that the correct frame can be retrieved. Even if frames are not positionally aligned with the feeding direction of a particular microfiche or even if the reference frame or the maximum address frame is not exposed on a microfiche, frames can automatically be positioned at a high speed simply by designating a plurality arbitrary frames which are actually exposed with images.
