It is provided so as to penetrate in the vertical direction. The engaging member 44 is fixed in the longitudinal direction thereof in accordance with the mounting direction (left-right direction) of the measuring table 10 to be engaged. The lower surface of the display unit 40 becomes a key type by the engaging member 44 hanging downward from the upper surface portion 42a, and covers the side surface of the inverted measuring table 10 from above, and the engaging member 44 is the corner portion between the side surface and the bottom surface. To fix the weighing platform 10. The engaging member 44 that directly engages with the measuring table 10 is made of a resin material or a rubber material so as not to damage the measuring table 10.

The U-shaped clamp 46 is a lateral U-shaped clamp having two horizontally extending arms 46e and a curved portion 46f connecting the back surfaces of the arms 46e. A recess 46b into which the back surface portion 42b of the metal bracket 42 fits is formed by being divided into upper and lower portions on the end portion, that is, the front surface of the arm portion 46e.

The arm portion 46e is formed with holes 46a penetrating in the extension direction (front-back direction) of the arm portion 46e at two locations, a total of four locations. A hollow columnar horizontal portion 22d is fitted into the U-shaped inner curved surface 46c, a screw 47 is inserted into the hole 46a of the U-shaped clamp 46 sandwiching the horizontal portion 22d, and the screw 47 is screwed into the screw hole 42c formed in the back surface portion 42b. It fits. The U-shaped clamp 46 with the horizontal portion 22d sandwiched between the inner curved surface 46c is fixed to the back surface portion 42b of the metal bracket 42, so that the display portion 40 is swingably supported by the horizontal portion 22d. The display unit 40 is held by the fastening force of the screw 47, and even if it is swung upward, it does not move downward due to its own weight and maintains the same angle.

There is a limit to the swing angle of the display unit 40. The horizontal portion 22d is provided with a screw hole 22e, and when the screw 48 is screwed into the horizontal portion 22d, the head 48a of the screw 48 protrudes from the outer surface of the horizontal portion 22d, and the head 48a becomes a protrusion of the horizontal portion 22d.

The inner curved surface 46c of the U-shaped clamp 46 is formed with a vertical groove 46d extending in the vertical direction at a depth up to the middle of the curved portion 46f so as to fit the head 48a as a protrusion. The mounting position of the U-shaped clamp 46 to the horizontal portion 22d is determined by using the head 48a as a mark, and the U-shaped clamp 46 is fixed by putting the head 48a in the vertical groove 46d.

When the display unit 40 swings in the vertical direction, the vertical groove 46d serves as a guide for the head 48a to guide the movement of the display unit 40. The display unit 40 can move only along the vertical groove 46d, and the horizontal movement and the vertical swing angle are restricted.

FIG. 9 is a partial cross-sectional view which is an explanatory view showing the relationship between the vertical groove 46d and the head 48a when swinging in the vertical direction. (A) indicates an upward swing, and (B) indicates a downward swing. As shown in FIG. 9, the display unit 40 swings in the vertical direction with respect to the head 48a, which is a protrusion of the horizontal portion 22d, about the horizontal portion 22d. When the display unit 40 is swung downward, the head 48a abuts against the lower surface 46h of the vertical groove 46d to prevent further downward rocking of the display unit 40 (see FIG. 9A), and the head portion 40 is moved upward. When the head 48a swings in the direction, the head 48a abuts on the upper surface 46g of the vertical groove 46d to prevent the display unit 40 from swinging further upward (see FIG. 9B).

In the present embodiment, the swing angle is limited, the screws are prevented from loosening in various places, and the holding force of the display unit 40 is maintained. It may be rotatably supported without a limiting angle. Further, the display unit 40 may be configured to be freely rotatable in both the horizontal direction and the vertical direction so that the measurement result can be easily confirmed.

As shown in FIG. 10, when the measuring table 10 is housed in the stand 20, the display unit 40 is first swung upward, the measuring table 10 is inverted and placed on the mounting surface 24a, and then the display unit 40 is placed again. Is swung downward to engage with the weighing platform 10. Specifically, the corner portion formed by the side surface and the bottom surface of the measuring table 10 is engaged with the stepped portion 44c of the engaging member 44 provided on the bottom surface of the display unit 40. Since the mounting height of the horizontal portion 22d is higher than the height of the inverted measuring table 10, the display unit 40 engages with the measuring table 10 in a state of being inclined downward from the horizontal. The measuring table 10 fits into the recess 27a, is fixed to the display unit 40 in a state of being supported by the support 22 while slightly tilting backward, and is held by the stand 20 in a stable state.

Since the measuring table 10 is held in an inverted state, the floor occupying area at the time of accommodation is small, and it can be stored in a space-saving space between shelves. Since the display unit 40 is used as the fixing tool, it is not necessary to prepare a dedicated fixing tool, and the fixing method is very simple as it is simply swung, and it can be compactly accommodated with a simple configuration.

Further, since the engaging member 44 provided on the bottom surface of the display unit 40 is caught on the bottom surface of the measuring table 10 and the measuring table 10 is tilted backward, a force is applied in a direction of further pushing the measuring table 10 backward. , There is no concern that the weighing platform 10 will tip over. Since the display unit 40 tilts downward from the horizontal state and engages with the measuring table 10, even if the holding force of the display unit 40 decreases and it cannot support itself, it swings further downward due to its own weight. Therefore, it is safe because the engagement is not disengaged without permission.

Although preferred embodiments of the present invention have been described, the present invention is not limited to the above configuration. FIG. 11 shows a weight scale 1A as a modified example. The scale 1A does not have a stand as a separate body, the above-mentioned stand 20 and the measuring table 10 are integrated, and a wide base 23 is rotatably attached to the measuring table 10 via a hinge to support the weight scale 1A. 22 extends upward and is used as a handrail.
