I doubt this game came out any earlier, it seems to be based off of Attack / Attack II by Sega.  It is certainly possible Attack was based off this machine, but unless I find a mention from earlier in 1972, I doubt it.  Instead of hitting the targets like in Attack, the buttons to hit each have a monster to hit.  The game has a time limit, but you can win a reply if you hit all 10 monsters.

One fascinating thing about this machine is that it was made with 日本娯楽機 (Nihon Gorakuki) who are one of the oldest amusement machine companies in Japan, dating back to the end of the end of the Meiji period.
