A force sensor particularly suited for use in an electronic stylus that senses the contact force on its nib for recording pen strokes and handwriting recognition. The sensor has a housing for a load bearing member for receiving an input force to be sensed and associated circuitry for converting the input force into an output signal indicative of the input force. The bearing member is movably mounted within the elongate body (up to 100 microns). The input force acting on the load bearing member is caused by contact on the nib. The load bearing member is biased against the direction of the input force. The force sensor also has a light source and photo-detector for sensing levels of illumination from the light source. Associated circuitry converts a range of illumination levels sensed by the photo-detector into a range of output signals, so that the illumination level sensed by the photo-detector varies with movement of the load bearing member within the elongate body such that the output signal from the circuitry is indicative of the input force. Using an optical sensor avoids the need to use a delicate piezo-resistive sensor that requires careful tolerancing during production.

To provide a liquid storage container which can prevent a failure that air bubbles are sucked into a liquid guide path even when the amount of liquid remaining in the liquid storage chamber is reduced and which can considerably reduce the amount of liquid discarded without being used.

[Solving Means] A liquid storage container 1 includes liquid storage chambers 370 and 430 from which liquid is guided to a liquid-supplying unit 50 through a liquid guide path and a liquid remaining-amount sensor 31 for detecting the presence/absence of the liquid on the basis of variation in residual vibration that occurs when air bubbles enter the liquid guide path. The liquid storage chambers 370 and 430 have concavities 374 and 434 in the bottom walls thereof. Liquid outlets 371 and 432 that communicate with the liquid guide path are formed at the bottom of the concavities 374 and 434, respectively. Therefore, air layers in the liquid storage chambers 370 and 430 are prevented from coming into contact with the liquid outlets 371 and 432, respectively, before the remaining liquid does.
