Claim:
A liquid supply implement comprising: a tank accommodating a liquid, said tank being divided into a plurality of tank portions; a tip end supply element which is located at a tip end side for supplying the liquid to an outside; a temporary storage chamber which temporarily stores the liquid overflowing the tank to prevent leakage of the liquid to the outside from the tip end supply element; and a selection mechanism provided between said tank and the tip end supply element, said selection mechanism selectively allowing the tank portions to communicate with the tip end supply element so as not to allow all the tank portions to communicate with the tip end supply element at the same time; and a joint core which connects the tip end supply element to the selection mechanism, wherein the temporary storage chamber is arranged around the joint core and can store the liquid overflowing from one of the tank portions which communicates with the tip end supply element by means of the selection mechanism.
