Attach a head element consisting of an analysis sample box holding rod, a coil spring, an analysis sample box holding plate, and a locking rod.
The head element is rotated by rotating the first support shaft, and the head element can be moved up and down by moving the second support shaft up and down. A preferred embodiment of the device will now be described in detail.

In the drawings, the reference numeral 1 indicates a base body, on which a first support shaft 2 is rotatably provided, and a first motor 3 mounted on the base body 1 with two first support shafts.
It is configured so that it can be rotated by being connected to the shaft 4 of.

A rotary plate 5 is attached to the end of the first support shaft 2, and the peripheral edge of the rotary plate 5 is located within the detection recess 7 of the first electrical detection element 6 mounted on the base 1. In this embodiment, the rotating plate 5 is a light blocking plate, and the first ′ql
Since the gas detection elements 6 are each composed of an optical switch element, the required openings (
(not shown) and the first electric detection element 6, the rotational position of the rotary plate 5 is detected and the rotational position of the first support shaft 20 is controlled.

Further, a second support shaft 8 is provided on the base body 1 at a position parallel to the first support shaft 2 so as to be movable up and down in the direction of arrow A, and a second support shaft 8 is provided on the base body 1 so as to be movable up and down in the direction of arrow A. Drive tooth i1
0 is engaged with the rack portion 11 of the second support shaft 8. At the lower end of the second support shaft 8, a support plate 12 whose entire shape is approximately doglegged in the direction orthogonal to the longitudinal direction of the second support shaft 8 is identified by the port 16. A first rotary plate 14 is rotatably attached to one end by a head element 15 mounted on a support plate, and the lower end 2a of the first support shaft 2 is rotatable at the center of the support plate 12. The second rotary plate 16 is rotatably supported at the lower end 2α. Said first,
A connecting rod 18 is operably connected to each end of the first rotating plates 14 and 16 via a pin 17, and the rotating plates 1'4 and 16 are simultaneously rotated by the connecting rod 18. possible to be connected.

The head element 15 includes an analysis sample box holding rod 15α, a locking rod 15b provided at the lower end of the rod 15b in a direction perpendicular to the axial direction of the rod 15α, and an analysis sample box holder provided above the rod 15b so as to be vertically movable. Plate 15c and this presser plate 1
Coil spring 15 to always push 5c downward
By rotating the first support shaft 2, the head element 15 is constructed of a connecting rod 18 and each rotating plate 14.d. It is rotated via the IS.

A pair of guide holes 19.2 at approximately the center of the main body 1 KH1
A pair of guide rods 21 and 22 for moving the device in one direction is loosely fitted into each guide hole 19.70, and a pair of guide rods 21 and 22 are loosely fitted into each guide hole 19. By sliding 19 and 20, the base body 1 is moved. Further, one end of the base body 1 vcld is attached with the second @ gas detection element 23, and the recess 25a of this electric detection element 23 is attached.
Vc is interposed with a shielding member 24 supported by a member not shown in this embodiment.

In the above configuration, when operating the head device for chemical analysis according to the present invention, firstly, when the second motor 9 is rotated, the second support shaft 8 is moved in the vertical direction via the drive gear 10 and the rack part 11. The base body 1 further moves in the lateral direction according to the guide rods 21 and 22.

As a result, the locking rod 15b provided on the head element 15 is positioned above the locking hole 25α provided in the analysis sample box 25, which is fixed in the rotational direction.

Thereafter, the second motor 9 is driven to drive the second support shaft 8 until the head element 15 is inserted into the locking hole 25 (Z) of the analysis sample box, and the second motor 413 is further rotated to rotate the second support shaft 8. At the same time as the first support shaft 2 rotates, the head element 15 provided on the support plate 12 via the connecting rod 18 rotates in the direction of the arrow.
By raising the support shaft 8, the 25 analytical sample boxes are lifted while being held by the locking rod 15b and the analytical sample box holding plate 15c. Therefore, for example, by sliding the device of the present invention on the guide rod 22 in this lifted state, the analysis sample box 25 can be moved to another location.

Since the head device for a chemical analyzer according to the present invention has the above-described configuration and function, the head element can be configured to be rotatable and movable up and down, and the chemical analysis container can be moved to any location. It is. In particular, the action of the analysis sample box holding plate and the coil spring provided in the head element are extremely effective in increasing the reliability of the operation of the apparatus of the present invention.
