An automatic analyzer is provided which applies a position detection mechanism to at least either a reagent probe or a reagent container transfer mechanism, thereby performing control on or inhibiting a reset operation (initialization) of either the reagent probe or the reagent container transfer mechanism to prevent the transfer thereof. This allows a reagent transport mechanism attached to the automatic analyzer automatically replacing reagent containers to be configured to move at the same height as those of various units including the reagent probe. The automatic analyzer is thus made small in size and allowed to operate without problems.

Automatic analyzer

The present invention provides an automatic analyzer including: an analyzing unit that includes an analyzing mechanism and a dispensing reagent cassette storage for storing a reagent cassette for dispensing; a reagent replenishing unit including a replenishing reagent cassette storage for storing in advance a reagent cassette for replenishing to be supplied as the reagent cassette for dispensing; and means for ejecting from the replenishing reagent cassette storage the reagent cassette for replenishing that cannot be supplied as the reagent cassette for dispensing.

The present invention provides an automatic analyzer for analyzing blood, urine, or other samples in which, for the purpose of reducing the workload of the operator, the process of reagent replacement is automated such that the measurement operation of the analyzer need not be halted during the reagent replacement. A sample rack transfer mechanism and reagent storage/transfer mechanisms are placed on different levels of two-story structure. This configuration allows reagent replacement even when the analyzer is performing an analysis, as well as achieving size reduction of the analyzer. The automation of reagent replacement is achieved by the following: a sensor's detection of the remaining reagent amount in a reagent vessel reaching a particular value; and the analyzer's detection of a measurement request for a sample rack when necessary reagents are not present in any reagent storage mechanism of an analyzer unit.

The present invention realizes proper driving circuits in a driving-circuit integral type liquid crystal display device which has an increased screen size. The liquid crystal display device includes a liquid crystal display panel and a driving circuit which supplies video signals to video signal lines formed on the liquid crystal display panel. The driving circuit is comprised of a first driving circuit which is formed in a step similar to a step for forming pixels provided to the liquid crystal display panel and a second driving circuit which is connected to the liquid crystal display panel after formation of the liquid crystal display panel. The first driving circuit is constituted of a switching circuit which is capable of distributing an output of the second driving circuit to a plurality of video signal lines.

Liquid crystal display device

A display device includes a display panel having a plurality of video lines, and a drain driver receiving n-bit display data, and connected to the plurality of video lines. The drain driver includes a gray-scale voltage generating circuit which generates M (M&#x3c;2) pieces of gray-scale voltages, a decoder circuit which selects two gray-scale voltages from the M pieces of gray-scale voltages based on upper-order bits of the n-bit display data, an operational amplifier which includes k (k&#x2267;3) pieces of non-inverting input terminals and one inverting input terminal connected to an output terminal of the operational amplifier, and a switching circuit which selects the two gray-scale voltages of the decoder circuit, and applies the two gray-scale voltages to the k pieces of non-inverting input terminals of the operational amplifier based on lower-order m (n&#x3e;m&#x2267;2) bits of the n-bit display data.

Display device

An automatic analyzing apparatus has an analysis section including an immunity analysis unit and a biochemical componential analysis unit. A sample rack which has undergone the immunity componential analysis is horizontally fed by a rack feeding mechanism from a position confronting the inlet of a rack stationing section to a position near the outlet of the rack stationing section, so that the sample rack is directly moved to a return line, while skipping over the rack stationing section, so as to be efficiently returned to the analysis section and subjected to a subsequent biochemical analysis. A sample rack that needs reexamination by an identical analysis unit is also returned in the same efficient way.

Automatic analyzing apparatus

The present invention provides a display device which can suppress the increase of a chip size while reducing the number of transistors of a decoder circuit compared to the prior art. Assuming m (m being an integer of 2 or more) as a lower-order bit in accordance with n-bit display data, a drive part includes a gray-scale voltage generating circuit which generates M pieces of gray-scale voltages where the gray scale number with respect to the gray-scale voltages is discontinuous, a decoder circuit which selects two neighboring gray-scale voltages out of M pieces of gray-scale voltages based on data of upper-order (n-m) bits in accordance with n-bit display data, and an output amplifying circuit which generates gray-scale voltages between two gray-scale voltages from two gray-scale voltages selected by the decoder circuit based on the data of lower-order m bits in accordance with n-bit display data and outputs the gray-scale voltages to the video lines.

The present invention provides a liquid crystal display device which can be used in a miniaturized portable device, wherein the liquid crystal display device has a small area for mounting driving circuits and allows the free mounting of the driving circuits. In the liquid crystal display device having a liquid crystal display element and a liquid crystal driving circuit, the liquid crystal driving circuit is mounted on one side of the liquid crystal display panel. Driving circuits for driving scanning signal lines are provided in plural. The scanning signal line driving circuits sandwich a circuit for driving video signal lines and are arranged in line with the video signal line driving circuit. Lines for transmitting signals to the scanning signal lines are connected to the scanning signal lines from left and right sides of the liquid crystal display panel so as to perform a control of the driving circuits in response to external signals.
