Long-object measuring device

Abstract

It is an object of the present invention to provide an elongated object measurement apparatus capable of measuring the length or quantity of elongated objects such as drugs arranged in a row, regardless of their size or type. One end of the elongated object is positioned with a first reference member and the other end thereof is positioned with a second reference member. The apparatus comprises a resistance circuit constituted by a plurality of resistors connected in series, wherein the resistor at one end is connected to a constant voltage source and the resistor at the other end is connected to the ground, a detection circuit comprising a plurality of switches disposed with uniform spacing along the elongated object and having one end thereof connected between the adjacent resistors and the other end thereof connected to a detection terminal, and a switch drive unit provided at the second reference member and turning the switches on. The voltage at the detection terminal of the detection circuit is measured and the length or quantity of the elongated material is computed based on the voltage.

Description

technical field [0001] The present invention relates to a medicine dispensing device that dispenses medicines stored in a cassette one by one, and more specifically, relates to a medicine that can measure the current quantity of medicines stored in a cassette, thereby confirming forgetting to take medicine or taking out medicine Dispensing device. Background technique [0002] Conventionally, when counting the current number of medicines (injections such as ampoules and vials) lined up and stored inside the cassette of the medicine dispensing device, non-contact sensors, optical sensors, etc. In reflective photosensitive sensors, the number of sensors that have detected medicine is taken as the current quantity of medicine (see, for example, Patent Documents 1 and 2). [0003] In addition, there are also attempts to print scales on the "empty stone" (Conston (registered trademark)) that applies force to the outlet of the ampoule inside the cassette in one direction at inter...

Problems solved by technology

[0014] However, in Patent Documents 4 and 6, it is necessary to change the distance between sensors according to various ampoules with different diameters, so there are cost barriers in assembly and mass production.

[0015] And in patent document 2, the belt is all printed scale with regard to the ampoules of every kind of different diameters, thereby needs a large amount of special editions

[0016] In addition, in Patent Documents 1, 3, 5, 7, and 9, even if the decrease in the number of ampoules can be detected, the current number cannot be detected, and inventory management is difficult.

[0017] The image recognition in Patent Document 8 without the above-mentioned problems detects the amount of medicine, which is costly and unrealistic
