Abstract: A push button panel 16, which has a transparent panel main body 16a for allowing a screen image on a display surface 10a to be visually seen, is disposed for each void part 15b between opaque frames 15a of a lattice panel 15 disposed on the display surface 10a of a monitor 10. Extended parts 16c are disposed at the four corners of an outer circumference of the push button panel 16, such that they are extending outwardly in the diagonal directions, and these extended parts 16c are fitted to recessed parts 15c provided at the four corners of an void part 15b of the lattice panel 15 . A rubber contact 17, in which electrodes functioning as detecting means are embedded in an elastic body functioning as supporting means, is disposed at a lower surface side of each extended part 16c.

Abstract: An interface unit 4 for a game machine 1 includes a monitor 10 having a single display surface 10a, and an input module 11 serving as an input device overlaid on the display surface 10a, wherein a plurality of push button panels 16, each of which has a panel main body with enough transparency to allow a screen image on the display surface 10a to be visually seen, partitions the unit 4 into input display parts 4a, which are arranged on partial regions of the display surface 10a in a push-down operable manner, and a multi purpose display part 4b for displaying a screen image with a different purpose from that of the input display parts 4a.
