FIG. 6 is a timing diagram explaining the operation of FIG. 5,
The diagram shows the operation of each component of the dental unit, with time plotted on the horizontal axis from when a patient accesses the dental unit, receives treatment, and leaves the unit.

The operation shown in FIG. 5 will be explained below together with the timing diagram shown in FIG. 6.

In the figure, first, until the patient approaches the seat 100 installed on the base 1 and takes a seat, the light support 7 is raised, the seat 100 is in the lowered position, the back seat 2 is in the upright position, The light support arm 6 and the light 5 housed at its tip are also in the raised position, and the light 5 is off.

Next, when the patient takes a seat on the seat 100 and turns on an auto-set switch (not shown) at time To, the light 5 turns on at a slightly delayed time T, and the back seat 2 is moved to a predetermined position 2' suitable for treatment. At the same time, the seat 100 rises and moves to the position 100' as it extends to 3' in step 3, where the patient's legs are placed (time T2).

When the seat 100 and the back seat 2 reach a time T2 at which they stop at a predetermined preset position, the light support 7 starts lowering and stops at a light lighting altitude position 6' suitable for treatment (time T3). The light will be at the 5' position. In this condition, the patient is treated.

In addition, each component of the treatment table (seat, back seat, light support) mounted on base 1 has been set in advance ti (1
(can be preset to the desired position).

If you want the patient to gargle during treatment, turn on the gargle reset switch (time T), the light 5 will go out, and the lie support 7 will be in the raised position at time Ts', and then the back seat will be turned on. 2 starts standing up, and at time T6, the back seat 2 is in the standing position. This results in
When a patient gargles, etc., the light comes into contact with their head, etc.
Patient movement (do not interfere with IE).

In order for the patient to finish gargling, etc. using the subton 4 and set it in the treatment position again, the back seat 2 starts tilting by turning on the auto-set switch (time T).
