Liquid supply reservoir
First Claim
1. In a liquid-supply reservoir of a liquid-using machine having a closable opening at the top of the reservoir in which are detachably secured both a pipe extending to near the base of the reservoir and a liquid-level sensing device forming a unit with the pipe, which pipe has an open end outside the reservoir through which a flexible conduit having one end connected to the liquid-using machine can be passed such that the other end is close to the base of the reservoir, the improvement wherein a part of the pipe has a recess formed on one side of an outside wall of the pipe, the liquid-level sensing device comprises a sensor secured to the outside wall of the pipe near a termination of the recess such that the sensor within the recess fits completely therein and every part of the pipe and sensor unit fits in the closeable opening with a slight amount of play.

Abstract
An improved liquid-supply reservoir in a liquid-using machine such as a copier is described. The improved reservoir is provided with a pipe and a liquid-level sensing device as one unit, which unit is detachably secured in an opening at the top of the reservoir. A flexible conduit, which has one end associated with the liquid-using machine, can be passed through the reservoir opening such that the other end is close to the base of the reservoir whereby liquid is conducted from the reservoir to the machine or the reverse. Freely slideable floats for sensing a minimum and/or a maximum liquid-level in the reservoir are secured in a recess on the outside of the pipe.
