  2. Description of the Related Art Conventionally, as an electronic weighing apparatus that measures the weight of an item, there is an electronic weighing device that calculates an amount of an item weighed based on a measured value when an item is weighed. Such an electronic balance device is used, for example, in a side dish department of a supermarket. The electronic scale device includes a PLU file (Price Look Up File) for an item for which the amount can be calculated, and calculates the amount of the item weighed by integrating the unit price and the measured value in the PLU file.

  Such an electronic scale device can display information on a display unit provided on the front surface (operator side) of the main body housing and a display unit provided on the back surface (customer side). Therefore, the electronic scale device is used by being placed on a showcase, for example, in a store that operates to sell sugar beet etc. via a showcase.

  By the way, such an electronic balance device is assumed to be used in a showcase or the like as low as the waist position of the operator. In this case, since the display unit on the operator side can be tilted, the operator can check the display contents. On the other hand, since the display section on the customer side is provided substantially perpendicular to the installation surface, there is a problem that it is difficult for the customer to confirm the display contents.

  The problem to be solved by the present invention is to provide an electronic balance device capable of improving operability.

  The electronic balance apparatus according to the embodiment includes a weighing unit that measures the weight of an item and outputs measurement value data, and calculates the amount of the item weighed based on the measurement value data.

  In the present embodiment, for example, in a side dish shop or a butcher shop where an operator who is a store clerk and a customer face each other through a showcase and sells a side dish or meat displayed in the showcase, An example of application to a facing electronic balance apparatus to be placed and used will be shown.

  Here, FIG. 1 is an external perspective view showing the electronic scale device 1 according to the embodiment from the operator side. As shown in FIG. 1, this electronic weighing apparatus 1 has a weighing pan 3 that is a placing surface on which a product whose weight is to be measured is placed on the entire top surface of a flat housing 2. The display 5 (display device with a touch panel) which is a display device provided with the touch panel 4 is provided on the left side of the front.

  The display 5 includes a thin LCD (Liquid Crystal Display) or an organic EL (Electro-Luminescence) as the display unit 5a. The display 5 is also provided with a keyboard section 6. A load cell unit 16 (see FIG. 7) that functions as a weighing unit that outputs the weight of an article as an electrical signal is provided inside the housing 2 and below the weighing pan 3.

  On the other hand, as shown in FIG. 1, the electronic balance device 1 is provided with a display 9 (display device with a touch panel) which is a display device provided with a touch panel 8 on the customer side as well as on the operator side. The display 9 also includes a thin LCD or organic EL as the display unit 9a. Therefore, the display 5 provided with the touch panel 4 and the display 9 provided with the touch panel 8 are provided on both sides of the apparatus with the load cell unit 16 functioning as the weighing unit interposed therebetween.

  Further, the display 5 and the display 9 are provided so as to be tiltable (tiltable) in the vertical direction with respect to the housing 2 with the upper end portion as an axis.

  For example, the display 5 can be tilted downward from the state shown in FIG. 1 so that its lower edge extends below the lower surface of the housing 2. This is in consideration of a usage mode in which the installation portion 7 of the housing 2 is placed on, for example, the upper surface of a showcase (not shown) and the electronic scale device 1 is installed, and the display 5 is positioned below the upper surface of the showcase. This is the structure.

  Further, as shown in FIG. 2, the display 5 can be positioned at a position substantially parallel to the weighing pan 3 by being tilted upward from the state shown in FIG. 1. Similarly, as shown in FIG. 2, the display 9 can be positioned at a position substantially parallel to the weighing pan 3 by being tilted upward from the state shown in FIG. 1. Thereby, even when the electronic balance device 1 is placed in a showcase or the like as low as the waist position of the operator, the operator and the customer can check the display contents of the display 5 and the display 9.

  As described above, when the display 5 and the display 9 are positioned substantially parallel to the weighing pan 3, that is, in a substantially horizontal plane, the display 5 and the display 9 are positioned about 5 mm below the weighing pan 3. The reason for configuring in this way is to avoid a situation where accurate weighing cannot be performed when an object of a size protruding from the weighing pan 3 is weighed on the display 5 and the display 9. .

  Further, as shown in FIG. 3, the display 9 can be positioned at a position substantially perpendicular to the weighing pan 3 by being tilted upward from the state shown in FIG. 1. By positioning the display 9 at a position substantially perpendicular to the weighing pan 3 in this way, the electronic weighing apparatus 1 can be used as a self-weighing at a store.

The support shafts 413a and 413b are concentric with each other and have an axial direction parallel to the display unit 9a and the surface direction. Hereinafter, the support shaft 413a and the support shaft 413b may be collectively referred to as the support shaft 413. The support shafts 413a and 413b protrude toward the fixed plate 411 from the side plates 412a and 412b, respectively. Caps 415a and 415b covering the protruding portions of the support shafts 413a and 413b are attached to the side plates 412a and 412b. A shaft support portion 414a is fixed to the upper surface of the right portion of the housing 2 when viewed from the display portion 9a side. Similarly, a shaft support portion 414b is fixed to the upper surface of the left portion when viewed from the display portion 9a side. The shaft support portions 414a and 414b hold the support shafts 413a and 413b, respectively, so as to be rotatable. Therefore, the display 9 moves to a vertical position where the display unit 9a is vertical as shown in FIG. 4 and an inclined position (FIG. 6) where the display unit 9a is moved in the direction of the arrow C or the direction of the arrow D. It is supported freely. The housing 2 is provided with a stopper (not shown). The stopper regulates the position movement of the display 9 by contacting the housing 9b of the display 9, and positions the display 9 in the inclined position. That is, the fixed plate 411, the side plates 412a and 412b, the support shafts 413a and 413b, the shaft support portions 414a and 414b, and the stopper constitute the support mechanism 401.

  In addition, in the state where the display 9 is positioned at the horizontal position, the same applies to the left side when viewed from the display unit 9a side, and the description thereof is omitted.

  When the display 9 is moved from the horizontal position to the inclined position in the arrow C direction, the arm 522a of the right torsion spring 511a as viewed from the display unit 9a side is pressed by the arm pressing part 513a and closed in the arrow C direction, The spring 511a accumulates a repulsive force. The display unit 9a is pressed in the direction from the horizontal position toward the inclined position by the repulsive force accumulated. Here, the pressing mechanism 501 is realized. At this time, the contact between the arm pressing portion (not shown) and the arm (not shown) of the torsion spring 511b is released. That is, no pressing force is applied to the arm (not shown) of the torsion spring 511b and its position is not changed, and no repulsive force is accumulated in the torsion spring 511b.

  Further, when the display 9 is moved from the horizontal position to the vertical position in the direction of arrow D, the contact between the arm pressing portion 513a and the arm 522a is released. That is, no pressing force is applied to the arm 522a of the torsion spring 511a, the position thereof is unchanged, and no repulsive force is accumulated in the torsion spring 511a. On the other hand, at this time, the arm (not shown) of the left torsion spring 511b as viewed from the display portion 9a side is pressed by an arm pressing portion (not shown) and closed in the direction of arrow D, and the torsion spring 511b has a repulsive force. Accumulate. The display 9 is pressed in the direction from the vertical position toward the horizontal position by the repulsive force accumulated. Here, the pressing mechanism 501 is realized.

  Thereby, the display 9 can be held at an arbitrary position between the vertical position and the inclined position. Such position holding is realized by a position holding mechanism 601 (see FIG. 5). The support mechanism 401, the pressing mechanism 501, and the position holding mechanism 601 constitute a tilt mechanism 701.

  As shown in FIG. 5, the shaft support portion 414 a included in the support mechanism 401 is mainly configured by a hollow cylindrical portion 441 a that opens toward the fixed plate 411. The hollow portion of the cylindrical portion 441a includes a first hollow portion 442a on the opening side, and a second hollow portion 444a separated from the first hollow portion 442a by a valve 443a formed on the inner peripheral surface of the cylindrical portion 441a. , Is composed of. A disc portion 445a having a slightly smaller diameter than the inner periphery (second hollow portion 444a) of the cylindrical portion 441a is provided integrally with the support shaft 413a at the tip of the support shaft 413a extending from the side plate 412a. The disc part 445a is accommodated in the second hollow part 444a. The disk part 445a is restricted from moving to the first hollow part 442a by contacting the valve 443a. The disk portion 445a is pressed against the valve 443a by a first leaf spring 611a and a second leaf spring 612a described later. In this way, the support shaft 413a is supported by the shaft support portion 414a. The support mechanism 401 located on the left side when the electronic scale device 1 is viewed from the front side has the same configuration.

  The torsion spring 511a included in the pressing mechanism 501 is wound around the cylindrical portion 441a of the shaft support portion 414a. The arm 522a has a direction along the winding direction of the torsion spring 511a. The tip of the arm 521a is bent in an L shape from the winding direction of the torsion spring 511a. An arm hole 541a penetrating in the axial direction of the support shaft 413a is formed in the arm holding portion 512a which is a part of the shaft support portion 414a. The arm 521a bent in an L shape is inserted into the arm hole 541a. In this way, the arm 521a is held by the arm holding portion 512a. The pressing mechanism 501 located on the left side when the electronic scale device 1 is viewed from the front side has the same configuration.

  The position holding mechanism 601 includes, in the second hollow portion 444a, a first leaf spring 611a that is curved in an arc as a first contact member, and a second leaf spring 612a that is curved in an arc as a second contact member. And have. Both the first leaf spring 611a and the second leaf spring 612a have elasticity. The first leaf spring 611a and the second leaf spring 612a are arranged to face each other and abut against each other at the curved portion. Both end portions of the first leaf spring 611a are in contact with a disk portion 445a that is also a part of the display portion 9a. Both end portions of the second leaf spring 612a are in contact with the cylindrical portion 441a. The second leaf spring 612a presses the first leaf spring 611a in the axial direction of the support shaft 413a. By this pressing, contact friction is generated between the first leaf spring 611a and the second leaf spring 612a. Due to the generated contact friction, the display unit 9a is held at an arbitrary position between the vertical position and the inclined position. Here, a position holding mechanism 601 is realized. The position holding mechanism 601 positioned on the left side when the electronic scale device 1 is viewed from the front side has the same configuration.

  As shown in FIG. 6, the display 9 moves around the support shaft 413 (support shafts 413a and 413b) and is held at an arbitrary position.

  Next, the electrical connection of each part built in the electronic balance apparatus 1 will be described with reference to FIG. As shown in FIG. 7, the electronic balance apparatus 1 is provided with a CPU (Central Processing Unit) 10 that executes various arithmetic processes and controls each part in a centralized manner.
