体にセッティングされことがある。2. Description of the Related Art Conventionally, an inverted microscope has been used as a microscope for examining a large sample such as a petri dish. In such an inverted microscope, since a micromanipulator may be operated on cells or the like during a microscope, peripheral devices such as these manipulators may be set in the microscope body.

ど、標本の交換をしずらいものにしていた。However, the arrangement of peripheral devices around the main body of the microscope reduces the space around the specimen,
When exchanging a sample, the observer's hand or the like may touch the surrounding devices, thereby changing the observation environment, making it difficult to exchange the sample.

As disclosed in Japanese Patent Publication No. 48-48, there has been considered an inverted microscope in which a retractable transmission illumination column is adopted so that a space around a sample can be made as large as possible.

At the time of microscopy, fine operations such as cell operations and delicate settings such as manipulators may be performed, and it is important to minimize the transmission of external vibrations to these operations.

る。[0007] In order to restrict the careless movement of such a transmitted light support, there has been proposed a structure in which a fixed amount of force can be set on the transmitted light support. FIG. 5 shows an overall view of a general inverted microscope having a transmitted illumination support column in which the amount of tilting force is set. The transmitted illumination support column 2 is provided on the microscope main body 1 so as to be able to be turned upside down. A light source (lamp house) 3 and a condenser (condenser) 4 are provided on the transmitted illumination support 2. In this case, the transmitted illumination support 2
As shown in FIG. 6, the base end is a pedestal 5 of the microscope main body 1.
Is rotatably supported via a shaft 6, and can be held in a state where it is tilted at a predetermined angle by bringing the stopper screw 7 into contact with the stepped portion 51 of the pedestal 5.
Can be held by screwing it on the pedestal 5.

している。In this case, in order to exert the amount of tilting force on the transmitted illumination support 2, the rotating portion with respect to the shaft 6 has sliding resistance, and when the fixing by the fixing screw 8 is released, the sliding resistance of the rotating portion is released. This prevents the transmitted illumination column 2 from suddenly falling down.

的とする。However, in such a configuration, since the amount of the force of fall of the transmitted light support 2 is constant, the light source (lamp house) 3 provided on the transmitted light support 2 and the light condensing light are provided. There is a problem in that the amount of fallable force is not optimal with respect to the variation in the setting weight of the container (condenser) 4 and the like. That is, the light source (lamp house) 3 and the condenser (condenser) 4
And the like are selectively provided, and the weight applied to the transmitted light support column 2 may vary. For example, when the weight applied to the transmitted light support column 2 is heavy, the amount of force falls, and the transmitted light support column 2 is tilted. The movement at the time becomes faster, and a shock due to the movement at this time may be given as a large vibration to a sample or the like. When the weight applied to the transmitted light support 2 is small, the amount of fallable force becomes heavy and the transmitted light support There is a problem that the operability is deteriorated such that a large force is required to defeat the 2. The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide an inverted microscope capable of improving the operability of a transmitted illumination support having a set amount of tilting force.
