Japanese Patent Laid-Open No. 2003-279866

  Traditionally, shops dealing with fabric products such as clothes have diversified their fabric patterns due to the recent diversification of personal preferences. This applies to more products, here fabric patterns, to increase satisfaction with more customers, but it would be unattractive to customers if they do not enhance their product lineup. . Especially for cloth patterns in Japanese clothes, a specific image is not understood only by catalog photos etc., whether the cloth is actually applied to the body and whether it fits your body shape and preference, and the pattern size is also large so Need to confirm. Moreover, since it is not easy in terms of money, it is necessary to obtain more accurate information. Under such conditions, it is not possible to obtain a sufficient understanding for the customer to purchase only with the photos posted in the catalog. For this purpose, an assortment of commodities corresponding to that is required, and therefore a space for securing the commodities is necessary and necessary. Therefore, if the current situation is grasped and neglected, the existence of the store itself is in danger.

  A flexible and foldable screen display device having a screen display portion and peripheral circuits arranged on a flexible substrate is wound on a roll, and this is brought into a housed state. By pulling out the screen display device from the wound state during browsing, an image is displayed on the flat portion, and the display content can be freely selected by an external operation switch, thereby solving the above-described problems.

  With a single paper display, there is an effect that space can be introduced and introduction of more products can be provided by displaying a plurality of products.

  Next, details of the present invention will be described in accordance with the description of the embodiments.

  FIG. 1 shows an embodiment of the present invention, wherein 1 is a paper display for displaying a fabric wound on a roll, 2 is a winding core portion for winding the paper display 1 on the roll, and inside the pattern on the paper display 1 A control circuit for displaying is incorporated.

  In FIG. 1, the paper display 1 is pulled out from the roll state, but the fabric pattern 1 a is displayed on the drawn-out plane portion. A plurality of patterns can be displayed on the fabric pattern, and the display content of the pattern can be changed by pressing a switch 2b provided on the core part 2. By displaying the number of the displayed pattern on the display device 2a, it is possible to confirm to which number on the catalog the current picture applies.

  In other words, every time the switch 2b is pressed, the product number of the display device and the design of the paper display 1 corresponding thereto are switched.

  Further, only the plane portion of the paper display 1 where the plane portion 1a is displayed is displayed. The display consumes power, but naturally the power consumption increases as the display area increases. By displaying only necessary portions, it is possible to minimize power consumption.

  These operations are shown in the block diagram of FIG.

  In FIG. 2, 11 is a switch for inputting a fabric number, 12 is a rotation detection encoder, 13 is a fabric number signal, 13 is a control circuit for outputting a display signal from the rotation detection encoder output, and 14 is a fabric number and fabric. A display circuit for displaying the pattern, 15 is a display device for displaying the fabric number, and 16 is a paper display for displaying the fabric pattern.

  By pulling out the paper display 1 in the process of 10, the flat portion 1a of the paper display 1 appears. By pulling out the paper display 1, the roll-shaped paper display 1 rotates. When the paper display 1 rotates to rotate a predetermined angle from the rotation detection encoder 12, a pulse is output. When the output pulse is input to the control circuit 13, the control circuit 13 counts the input pulse and calculates the rotation speed of the roll. The display area of the paper display 1 corresponding to the rotational speed is input to the paper display 1 as a display signal to the display circuit 14. By doing so, a certain area is displayed on the paper display 1.

  The switch 11 receives the pattern number of the fabric, and inputs the pattern number to the display circuit 14. A signal for outputting a predetermined number is input to the fabric number display device 15 from the pattern number signal, and the fabric number display device 15 displays the number designated by the switch 11.

  The flat portion 1a of the paper display 1 generates a force that urges the paper display 1 to the side opposite to the pulling direction of the paper display 1 so as to keep the flat surface even when the paper display 1 is pulled out.

  The structure will be described.

  3 and 4 are sectional views of the present invention. The core 2 of the roll has a fixed portion 2c that is fixed regardless of the rotation of the roll, a rotating portion 2d that rotates the same as the rotation of the roll, and a force that is biased to the opposite side of the pulling direction when the roll is pulled out. It is comprised from the spring part 3 which outputs. The spring portion 3 is a spring on the mainspring, and each end portion of the spring is connected and held by a fixed portion 2c and a rotating portion 2d.

  FIG. 3 is a sectional view of the housed state, that is, a state where the flat portion 1a of the paper display 1 is not pulled out. The spring portion 3 remains in a state in which a force is acting on the side opposite to the pulling-out direction of the paper display 1 in a slightly tightened state with respect to the released state. In FIG. 4, when the paper display 1 is pulled out in a state where the flat surface portion 1a of the paper display 1 is pulled out, the roll portion rotates, and the rotating portion 2d also rotates accordingly. When the rotating portion 2d rotates, the end portion on the spring 3 rotating portion 2d side also rotates, and the spring portion 3 rotates in the direction in which the mainspring is tightened. On the other hand, the end portion of the spring portion 3 on the fixed portion 2c side does not rotate, and the connection holding position remains unchanged. That is, the spring portion 3 changes to a shape in which the mainspring is tightened. The spring portion 3 has a force acting in the releasing direction, and in FIG. 4, the force is acting in the clockwise rotation direction. That is, force acts on the opposite side with respect to the pulling direction of the paper display 1.

  By doing so, the plane part 1a of the paper display 1 can be kept flat.

  FIG. 5 shows a second embodiment in which a paper display is applied to a tape measure.

  Various units of dimensions are used throughout the world, such as meters and inches, and some of the units to be measured cannot be understood unless they are unique units. In the case of a conventional tape measure, a dedicated unit is displayed, so when measuring the length in another unit, the tape measure of the dedicated unit must be used again. This is an example in which the present invention is used to eliminate such inconvenience.

  Reference numeral 101 denotes a tape measure body, 102 denotes a switch for changing display contents of the tape measure, and 103 denotes a display unit for displaying a unit of the tape measure and a representative dimension.

  Reference numeral 101a denotes a paper display, and a scale of dimensions is displayed in this embodiment. By pressing the switch 102, the display of the necessary unit can be changed, and the unit is displayed on the display device 103. Further, 101b is displayed thick and long in the displayed scale farm, and the dimension of the part is displayed as a numerical value on the display device 103 as a representative dimension. This dimension serves as a guide for measurement.

  FIG. 6 shows a third embodiment. This embodiment is applied to a hanging shaft. 201 is a paper display winding unit, 202 is a paper display unit, and 203 is a weight. The image displayed on the paper display unit 202 can be switched by pressing the switch 201a. The weight 203 is a weight for preventing the paper display unit 202 from being stored in the take-up unit 201 against the force on the opposite side to the pulling direction generated because the paper display unit 202 is pulled out.

  In the embodiment, the picture displayed on the paper display unit 202 is a painting, but it is possible to switch to an arbitrary image by pressing the switch 201a in the season, the situation where it is placed, and the atmosphere in the place.
