PROBLEM TO BE SOLVED: To provide a plate material positioning structure of a horizontal multistage press apparatus capable of efficiently performing heating and pressurizing treatment by correcting the feed-in insufficient state of a plate material to be treated and capable of preventing the occurrence of an inferior product such as thickness unevenness or the like of the treated plate material. SOLUTION: A hot press part 100 is equipped with the stoppers 170 and proximity switches 10a-10n arranged on the front side (head side) of (n) feed-in routes Ka-Kn in the (n) feed-in routes Ka-Kn provided corresponding to (n) plate materials W1 to be treated and (n) operation arms 180a-180n arranged on the rear side (terminal side) of the respective (n) feed-in routes Ka-Kn. The stoppers 170 are arranged at the feed-in stop position of the respective plate materials W1 so as to straddle all of the feed-in routes Ka-Kn and the respective proximity switches 10a-10n detect that the respective plate materials W1 are fed in up to the stop position while the respective operation arms 180a-180n are re-feed in the respective plate materials W1 in a feed-in insufficient state along the corresponding feed-in routes Ka-Kn.
