When is equal to the moment (969.75kgf·mm), the head 10 can maintain equilibrium without sagging. Here, theta may be an angle (acute angle) between the longitudinal direction of the gas springs 51 and 52 of the support arm 50 parallel to the horizontal line and the horizontal line. That is, F(Gas) is the longitudinal force of the gas springs 51 and 52, and can be 4.806kgf·mm/Sin(theta) for the above equilibrium. As theta is greater than 0, the gas springs 51 and 52 may be advantageous in maintaining the above equilibrium.

In addition, the moment to raise the rear part 422 by the gas springs 51 and 52 is the product of F (Gas), Cos (16.5 degrees), and vertical distance (H51), that is, 68.6 × F (Gas) kgf · It can be mm. Here, F (Gas) may be the force of the gas springs 51 and 52, and when 910.3 + 53.6 × F (Gas) < 68.6 × F (Gas), that is, F (Gas) > 60 kg, the rear part (422 ) The moment to lower and the moment to raise can be in equilibrium. At this time, the length L51 of the gas springs 51 and 52 may be smaller than the length L50 of the gas springs 51 and 52 of the support arm 50 parallel to the horizontal line (see FIG. 28).

In this case, the second positioning unit 672 and the first upper unit 651 may be aligned or slightly misaligned with each other. Accordingly, unless an external force above a certain level (i.e., a force pulling the slider 66 downward) is applied, the position of the slider 66 is between the second positioning unit 672 and the first upper unit 651. It can be held in place by magnetic coupling.

When the slider 66 is lowered to the maximum with respect to the rotating parts 65b and 65c (for example, when the upper blocks 661a and 661b are caught on the protrusions 65X1 and 65X2), the second positioning unit 672 1 You can face the lower unit (652). In this case, the second positioning unit 672 and the first lower unit 652 may be aligned or slightly misaligned with each other. Accordingly, unless an external force above a certain level (i.e., force pushing the slider 66 upward) is applied, the position of the slider 66 is determined by the magnetic field between the second positioning unit 672 and the first lower unit 652. It can be fixed by bonding.

For example, the distance H6 between the top dead center and the bottom dead center of the slider 66 may be 35.7 mm.

Accordingly, the user can carry the head 10 with the slider 66 close to the cover 68 or hold the handle 662 with the hand while pulling the slider 66 away from the cover 68.

Referring to FIGS. 50 and 51, the moving ring 62 of the stand 60 and the slider 66 fixed thereto may rotate in the circumferential direction of the supporter 613.

In addition, when the protrusions 641P and 642Q are reinserted into the grooves 622P and 622Q in response to the rotation of the moving ring 62 and the slider 66, the shapes of the stoppers 641 and 642 can be restored. And, unless an external force above a certain level (i.e., force to rotate the moving ring 62 and the slider 66) is applied, the rotation of the moving ring 62 and the slider 66 can be stopped. The user rotating the slider 66 can detect separation of the protrusions and grooves and recombination of the protrusions and grooves.

When the first protrusion 641P is inserted into the first groove 622P and the second protrusion 642Q is inserted into the second groove 622Q (see FIG. 42), the slider 66 is inserted into the lower side of the head 10. may be adjacent (see Figures 46 and 48). When the second protrusion 642Q is inserted into the first groove 622P and the first protrusion 641P is inserted into the second groove 622Q, the slider 66 may be adjacent to the upper side of the head 10 ( 50).
