A simple and convenient analyzing apparatus is provided which easily, conveniently, and efficiently collects a material in the state of fine particles adhered to a target object, extracts the object to be analyzed, and analyzes the extracted object. An apparatus for detecting fine particles in a gas which sucks the gas under measurement from the target object by using a suction pump, extracts the fine particles contained in the gas under measurement, and performs measurement by using a spectrometer is embodied such that an inertial impactor for collecting the fine particles having diameters not less than a specified particle diameter is disposed upstream of the spectrometer, the fine particles are collected in the fine particle collector of the inertial impactor, the collector containing the collected fine particles is heated such that the collected fine particles are vaporized into a gas, and the vaporized fluid to be examined is supplied to the spectrometer to be measured thereby.

Analyzing apparatus and fine particle collecting apparatus

At least one automaton for collectively controlling media inclusive of notes in a shop is located in a first corner, at least one automaton operated by customers is located in a second corner and at least one automaton operated by a clerk who is contacting or negotiating with a customer is located in a third corner. The automatons in individual corners are interconnected together by a sheet conveyor for aligning and conveying the media such as notes one by one. The amount of media stored in each automaton in each corner is always supervised and media are conveyed between automatons, as necessary, to effect supplementation/withdrawal of media. Furthermore, sheets are conveyed between opposed magnetic belts.

Group supervisory system for moving sheets between multiple automatons

A medium transferring apparatus which makes use of a preliminary transference stage prior to a main transference stage at the time of transference of a medium such as a sheet of paper. In the former stage, an initial parameter setting operation is performed so that a desired amount of feeding of the medium and control parameters for achieving this feed amount, including the amount of control rotation, rotational speed and acceleration on starting of a transferring motor are automatically determined on the basis of external factors used as parameters such as the number of operations of the transferring apparatus, the type of the medium and desired environmental factors of use of the apparatus including temperature and humidity. In the initial parameter setting operation, an unknown friction coefficient of the medium is determined. In the main transference stage, data thereby obtained enables the medium to be transferred with constant accuracy no matter what the thickness, difference in level, friction coefficient of the medium, as well as environmental factors.

Medium transferring system

This invention relates to a apparatus for separating and feeding sheets such as sheets of paper comprising an accommodation box for accommodating the sheets of paper stacked by their own weight, a pick-up roller provided so that the upper surface thereof projects into the interior of the box to bear the weight of the stacked sheets of paper, a separation arrangement comprising a frictional roller and the feed roller and provided so as to face an ejection port of the accommodation box from which sheets are sent out to the separation arrangement, and a support arrangement disposed on the side opposite to the ejection port supports the end, opposite to the ejection port, of the sheets of paper, and for allowing the lowermost sheet end to be free of the weight of the sheet thereabove when the lowermost sheet is moved to the ejection port side so that frictional resistance of the lowermost sheet is reduced greatly and the pick-up roller can surely pick up and convey the sheet one by one from the lower side of the sheets. The support arrangement comprises a roller freely rotating or a roller driven by a driving device, the latter have a circular or elliptical cross-sectional shape. The elliptical roller vibrate the end portion of the sheets opposite to the ejection port to make gaps therebetween.
