A circuit substrate includes protruding terminals and has a structure that ensures an excellent connection with an electronic component, such as an IC. It comprises a nozzle structure which is provided with coaxially arranged nozzle elements and is arranged to form one or more layers which cover a flexible elongated element on the surface of the flexible elongated element, which passes through the innermost nozzle element, and a guide member corresponding the diameter of the elongated element for controlling the flexible elongated element. The first loop has an opening commensurate with a width of the flexible strap, so that the second end portion can freely pass through. In response to receiving a shift signal, control functionality that is coupled to the plurality of storage locations and to the shift FIFO may cause the instruction that is next in the program order to be moved from a given location of the plurality of storage locations to the entry of the shift FIFO. A controller replaces each dummy image data item in the image file with a display image data item to generate a new image file and causes a display unit of a terminal apparatus to display the image file. While repeating alternately between each of the display panels in a display period within a one frame period, an operation sequentially selects a number of the scanning lines of each of these display panels corresponding to the ratio of the numbers of the scanning lines in each of these display panels at predetermined scan timing.
