The display operation device 4 is mounted on a mounting projection 15 formed on the lower housing 2b via a through hole 18 formed on the upper housing 2a and via a mounting hole 12a formed on the flat surface 12. It is detachably attached to the main body housing 2 by screwing an attachment screw 20 into the screw hole 19. Here, the mounting mechanism is realized by the mounting hole 12a, the mounting screw hole 19, and the mounting screw 20.

The lower receiving recess 14 is formed with a screw hole (not shown) into which screws for fixing various components such as the load cell unit and the control board are screwed. In the lower housing 2b, the opening directions of the lower housing recess 14 and the mounting projection 15 and the mounting screw hole 19
And the other screw holes are formed in the same direction as the extending direction. Thus, the lower housing 2b can be formed by die casting.

The lower housing 2b of the present embodiment
Is formed by die casting using aluminum as a main material.

By molding the lower housing 2b by die casting, the lower housing 2b having high strength and good dimensional accuracy can be easily formed.

As the lower housing having the lower housing recess 14 and the mounting projection 15, for example, FIG.
A lower housing 30 shaped as shown in FIG. However, in order to achieve high strength and high accuracy, FIG.
When the lower housing 30 having a shape as shown in FIG. 10A is formed by die casting, the lower housing 31 is actually formed as shown in FIG. . For this reason, unnecessarily many materials are required for the front part 31a of the lower housing 31, and the weight of the lower housing 31 increases. In the present embodiment,
By using the lower housing 2b having the shape as shown in FIG. 4, the lower housing 2b with high accuracy and high strength can be formed of the minimum necessary material.

In addition, although not particularly shown, the weighing device 1 includes:
A control unit for driving and controlling each unit in the weighing device 1 is provided.
Thereby, the printer, the LCD 8, the touch panel 9,
It becomes possible to drive and control each unit such as a label issuing machine.

In such a configuration, when a product is placed on the plate 3, the weighing device 1 outputs an output value from a load cell unit (not shown) according to the weight of the product placed on the plate 3. The control section calculates the weight data of the product placed on the plate 3 in the control section, and displays the calculated weight data on the LCD 8.

By the way, the installation place of the weighing device 1 and the weighing device 1
The height and the inclination angle of the display / operation device 4 that feel comfortable are different depending on the height and the like of the operator who uses the device.

In the present embodiment, since the display operation device 4 is attached to the main body housing 2 via the hinge 10, the operator grasps both ends of the casing 7 when using the weighing device 1. By applying a force in the opening and closing direction of the hinge 10 in this state, the display operation device 4 can be tilted to an arbitrary position where operability is sufficiently secured.

At this time, the inclination angle of the display operation device 4 with respect to the main body housing 2 is changed by the hinge 10 to the casing 7.
4A, the lower end of the casing 7 is lower than the lower end of the main body housing 2 from the first tilt position (the angle shown in FIG. It can be tilted to any position within the range up to the angle shown in FIG.

Thus, even when the dimension in the height direction of the casing 7 of the display / operation device 4 is longer than the dimension in the height direction of the main body housing 2, it is not necessary to increase the height of the main body housing 2. Further, when the display operation device 4 is tilted, only the display operation device 4 is tilted, so that it is not necessary to increase the installation space of the weighing device 1.

The hinge 10 according to the present embodiment is opened and closed by
Until the operator operates the touch panel 9 with a normal force while the display operation device 4 is attached to the main body housing 2, a force greater than or equal to a force within a range estimated to be applied to the hinge 10 is applied. , Is not allowed. Thus, the inclination angle of the display operation device 4 does not change carelessly during operation. Stable operability of the display operation device 4 attached to the attachment projection 15 can be provided.

Further, when the display operation device 4 is operated, the display operation device 4 is operated by the operator, so that a downward pressing force acts on the lower housing 2b. In the present embodiment, since the lower housing 2b is formed by high-strength aluminum die-casting, the stability of the weighing device 1 is not lost, and the stable operation of the display operation device 4 is provided. Can be.

In addition, by attaching the display / operation device 4 to the attachment projection 15, the plane 12 can be attached at a position higher than the lower end of the main housing 2. Thus, it is possible to prevent the display operation device 4 from protruding extremely below the lower end of the main body housing 2.

When the display operation device 4 is tilted, the lower end position of the display operation device 4 is lowered as the display operation device 4 is closer to the vertical. When the inclination angle of the display operation device 4 with respect to the main body housing exceeds a certain angle, the lower end of the display operation device 4 projects downward from the lower end of the lower housing 2b, that is, the table on which the weighing device 1 is installed. Will be done. This protrusion does not cause any problem if it is a little. However, for example, in a case where the main body housing 2 is installed on a drawer device and used, an inconvenience may occur depending on the installation location of the weighing device 1. I am concerned.

Since the display / operation device 4 of the present embodiment is detachable from the main body housing 2, in such a case, the display / operation device 4 is detached from the main body housing 2 by the following procedure. Only the display operation device 4 can be moved.

At the time of attachment / detachment, first, the display operation device 4 is tilted to the position shown in FIG. Display operation device 4
Is tilted to the position shown in FIG. 4B, the mounting screw 20 can be visually checked from above as shown in FIG.

In this state, the display operation device 4 can be detached from the main body housing 2 by removing the mounting screw 20. At positions other than those shown in FIG.
Since the mounting screw 20 cannot be visually recognized from above, the mounting screw 20 is prevented from being unnecessarily exposed, and the mounting screw 20 is prevented from being corroded due to, for example, gravy dripping from the plate 3. Thus, the mounting screw 20 can be protected.

The display / operation device 4 detached from the main housing 2 can be used by being installed next to the main housing 2 as shown in FIG. 6, for example. here,
FIG. 7 is an exploded perspective view showing a state where the display operation device 4 is detached from the main body housing 2. The display operation device 4 detached from the main body housing 2 can be attached to the support member 21 by screwing the flat surface 12 of the hinge 10 into an attachment screw hole 21 a formed in the support member 21 with the attachment screw 20. It is possible. The lower end of the support member 21 is fixed to the installation plate 22.

In use, the main body housing 2 is placed on the installation plate 22, and the display operation device 4 is attached to the support member 21 for use. Accordingly, even when the display operation device 4 is operated, the support member 21 can be indirectly fixed by fixing the installation plate 22 by the weight of the main body housing 2, and the display operation device 4 can be moved from the main body housing 2. Even when used after being detached, operability and stability are not impaired.

Further, by forming the mounting screw holes 19 in the support member 21 as well, the display operation device 4 can be connected to the mounting screw holes 21a by screwing the mounting screws 20 into the mounting screw holes 21a as in the case of mounting to the main body housing 2. It can be attached to the support member 21.

Thus, the display / operation device 4 can be attached to the support member with a practically simple configuration, and the work of attaching the display / operation device 4 can be simplified.

In addition, since the display operation device 4 is always mounted with the same mounting screw 20,
Can be prevented from being lost.

In the present embodiment, the display operation device 4 detached from the main body housing 2 is mounted on the support member 21 connected to the installation plate 22. However, the present invention is not limited to this. A bar-shaped support member 23 as shown in FIG. 8 can be attached to the flat surface 12 of the hinge 10 attached to the back side of the display operation device 4 detached from the main body housing 2.

The support member 21 has screw holes 19 and 21a.
By forming the same screw hole (not shown) as
The display operation device 4 and the support member 23 can be mounted by screwing the mounting screws 20 together. The support member 23 has a mounting portion where the display operation device 4 is mounted.

When the support member 23 is attached, the casing 7 and the support member 23 are
The opening and closing angle of the hinge 10 can be easily adjusted to an arbitrary position by the leverage principle.

By providing such a support member 23, the operator can use the display operation device 4 by moving it to an arbitrary position where good visibility is ensured.

In this case, stable operation can be provided by operating the display operating device 4 by providing a non-slip (not shown) or the like at the lower end of the support member 23.

In addition, by providing such a support member 23, the swivel adjustment of the display / operation device 4 can be adjusted freely. This allows the operator to tilt the display operation device 4 to an arbitrary position where operability is ensured, and to use the display operation device 4 by swiveling it according to the convenience of the installation location or the like. .

As described above, in order to enable the display operation device 4 to be detached from the main body housing 2 and used depending on circumstances such as the installation location in the market, power is supplied to the display operation device 4. The length of the cable L needs to be set with some allowance.

On the other hand, when the display operation device 4 is attached to the main housing 2 and used by setting the cable L to be long, there is a concern that the long cable L may interfere.

As a countermeasure, it is conceivable to set the length of the cable L for each customer according to the usage in the market. In this case, it is necessary to manufacture a weighing device according to the specifications for each customer. In addition, there is a concern that productivity may decrease.

In this embodiment, since the space F is formed below the mounting projection 15, an unnecessary cable L can be wound and stored in this space F. Accordingly, it is possible to prevent the cable L from being in the way when the display operation device 4 is attached to the main body housing 2.

In addition, in this embodiment, since the lower housing 2b is formed by die-casting aluminum, it is easy to form a space below the mounting projection 15.

In this embodiment, the main housing 2 is formed by vertically fitting the upper housing 2a and the lower housing 2b (see FIG. 3). However, the present invention is not limited to this. Alternatively, the main housing 2 may be formed by fixing the upper housing 2a and the lower housing 2b with a hook or the like.
