  In addition, there is a product data processing apparatus in which the screen of the display unit can be used on the operator side or the customer side.

  That is, when used on the operator side, the display unit is closed and the screen is viewed as being superimposed on the apparatus main body. When used on the customer side, the operator opens the display unit and stands up with respect to the apparatus main body so that the screen is directed to the customer side.

  By the way, the pivotal support portion of the display unit described above is constituted by, for example, a hinge mechanism, and even if the hand is released during the opening operation of the display unit by increasing its rotation torque, the display unit is released without being lowered by its own weight. A so-called free stop that holds the position is realized (for example, see Patent Document 1).

  However, in the past, since the free torque was realized by increasing the rotational torque of the hinge mechanism, the product data processing device of the small POS system is light in weight, so the display unit is lifted and opened. In this case, the apparatus main body may be lifted. For this reason, the display unit must be opened by holding the device main body by hand so that the device main body does not rise, and the operability is poor.

  The present invention has been made paying attention to the above circumstances, and its object is to realize a free stop of the display unit without increasing the rotational torque of the pivotal support unit, and a product data processing apparatus having excellent operability. Is to provide.

  In order to solve the above-described problems, the present invention provides a device main body, a display unit that is provided on the upper surface of the device main body through a pivotal support so as to be openable and closable, displays information, and is provided in the pivotal support. And urging means for urging the display unit in the opening direction.

  ADVANTAGE OF THE INVENTION According to this invention, the free stop of a display unit is implement | achieved without enlarging the rotational torque of a pivot part, and the goods data processing apparatus which is excellent in operativity can be provided.

The perspective view which shows the state which opened the display unit of the goods data processing apparatus of FIG. The perspective view which shows the pivot part which pivots the display unit of FIG. 2 so that opening and closing is possible.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a perspective view showing a product data processing apparatus according to an embodiment of the present invention.
The merchandise data processing apparatus 1 includes an apparatus main body A and a display unit B whose upper edge is pivotally supported on the upper surface of the apparatus main body A so as to be freely opened and closed. The apparatus main body A is provided with an open / close button 6, and when the open / close button 6 is pressed, the engagement between the lower edge side of the display unit B and the apparatus main body A is released. With this release, the display unit B can be opened in the direction of the arrow as shown in FIG.

  The apparatus main body A includes a front face portion provided with a power button 2, a USB (registered trademark) port 3, a front cover A1 that is openable and closable so as to cover an upper edge portion of the front face portion, and one side face portion. A side cover A2 that can be freely opened and closed is provided to cover the part.

  The front cover A1 is provided with a receipt issuing port 5 and the opening / closing button 6 described above. A receipt printed by a printer (not shown) built in the apparatus main body A is discharged from the receipt issuing port 5.

  The display unit B is provided with a touch panel display 7 and a card reader 8. The touch panel display 7 functions as a GUI (Graphical User Interface) capable of both displaying processing contents and inputting operations. The card reader 8 reads data recorded on these cards by inserting and sliding various magnetic cards such as credit cards and point cards and IC cards.

  When the display unit B is opened, the receipt paper 9, the platen cover 10, the platen roller 11, and the upper cover A3 are exposed on the upper surface of the apparatus main body A. The receipt paper 9 is a color-type thermal paper that is wound in a roll shape and whose printing surface is discolored by heating. When the platen cover 10 is closed, the receipt paper 9 is pressed by the platen roller 11, and the receipt paper 9 is heated by a thermal head (not shown) arranged opposite to the platen roller 11 across the receipt paper 9. Processing information and the like are printed.

  By the way, the display unit B described above is attached to the apparatus main body A through a pivotal support portion 15 so as to be opened and closed as shown in FIG.

  Concave portions 16 are formed on both side portions on the upper green inner surface side of the display unit B (only one concave portion is shown), and a synthetic resin hinge 17 is provided in the concave portion 16. The hinge 17 is fixed to the inner bottom surface of the recess 16 by a fixing screw 18, and a metal shaft 21 is inserted into the bearing hole 20 of the hinge 17. One end of the metal shaft 21 is fixed to the inner wall surface of the recess 16, and the other end is fixedly supported by a support leg 22. The support leg 22 is fixed to the upper surface portion of the apparatus main body A by a fixing screw 23.

  On the other hand, a torsion spring 24 as a biasing member is attached to one end of the metal shaft 21. The torsion spring 24 includes a coil portion 24a and both arm portions 24b and 24c extending from both sides of the coil portion 24a, and the metal shaft 21 is inserted into the coil portion 24a.

  The torsion spring 24 has an urging force in a direction in which both the arm portions 24b and 24c are expanded, one arm portion 24b is brought into pressure contact with the upper surface portion of the apparatus main body A, and the other arm portion 24c is brought into contact with the concave portion 16 of the display unit B. It is in pressure contact with the inner bottom surface.

  The torsion spring 24 is biased in the direction to open the display unit B by the spring force. When the operator opens the display unit B, the torsion spring 24 functions as an auxiliary force for assisting the opening. When the hand is released from the unit B, a so-called free stop is realized that stops at that position so that the unit B does not fall by itself.

  Next, a method for using the product data processing apparatus 1 configured as described above will be described.

  First, when used on the operator side, the display unit B is closed as shown in FIG. 1, and in this state, the display 7 is touched to perform an input operation, and the displayed processing contents are observed.

  When the display unit B is used on the customer side, the operator presses the open / close button 6 to release the lock of the display unit B and lifts the lower green side of the display unit B. At this time, the spring force of the torsion spring 24 is supplementarily applied as the push-up force of the display unit B, and the display unit B is smoothly pushed up and released. When the display unit B is opened at a predetermined angle and the display 7 is directed to the customer side, the operator releases the display unit B. At this time, the display unit B is held by the spring force of the torsion spring 24 and realizes a free stop without dropping due to its own weight. The customer obtains information by viewing the displayed content of the display 7.

  After the customer finishes viewing the information on the display 7 of the display unit B, the operator pushes the display unit B down against the spring force of the torsion spring 24 and closes it.

  As described above, according to this embodiment, the spring force of the torsion spring 24 urges the display unit B in the opening direction, so that a free stop is realized without increasing the rotational torque of the hinge 17. be able to.

  Therefore, even if the display unit B is lifted, there is an advantage that the apparatus main body A does not float and the operability can be improved.

  Further, when the display unit B is closed, the display unit B is pushed down against the spring force of the torsion spring 24, so that the display unit B is not suddenly closed.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.
