We consider a class of games which is suggested from the timing 
problems for putting some kind of farm products on the market. N players take
possession of the rights to put some kind of farm products on the market with 
even ratio. Each of the $n$ players can put the farm products at any time in $[0, 1]$. 
The price of them increases over $[0,m ]\subset [0, 1]$ and decreases over $( m,1]$ 
with pass time $t$  as long as none of the $n$ players takes his action, however if one 
of the $n$ players put his farm products on the market the price falls discontinuously
and then fluctuates analogously as before. All players have to put their farm 
products on the market within the unit interval $[0, 1]$. In such a situation, each 
player wishes to put at the optimal time which gives him the highest price, 
considering opponents' action time with each other. This model yields us a certain 
class of $n$ person non-zero sum infinite games.
