JPS60132781A - Rolled recording paper - Google Patents

Abstract

PURPOSE:To provide a rolled recording paper free from disturbance to recording job, for example, shortage of the recording paper in the course of work by forming a residual amount display section at a part of the surface void of recording information is recorded to always learn the residual amount of the recording paper. CONSTITUTION:A coloring section 1a or the like is formed continuously or at a fixed interval on the surface void of recording information of a rolled recording paper 1, for example, at the end of the back thereof. For example, the recording paper 1 is previously colored varying in color, green yellow red, from the initial to final end, a user is allowed to learn the residual amount observing the color of the colored section 1a.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a roll of recording paper, and more particularly to a roll of recording paper with improved remaining amount display.

[Prior Art] Generally, a monochromatic color is applied to the side edge of the roll of recording paper in the width direction to indicate when the remaining amount is below a certain length. A warning is displayed when the remaining capacity is below a certain length.

However, in such a warning display, the colored portion suddenly appears, so that if a long recording sheet is required for -times of recording operations, the recording sheet may run out even during the recording operation.

[Objective] The present invention has been made in order to eliminate the above-mentioned conventional drawbacks, and its purpose is to provide a roll of recording paper configured to constantly display the remaining amount of recording paper. There is.

[Example] Hereinafter, the present invention will be described in detail based on the example shown in the drawings.

[First Embodiment] Fig. 1 explains the first embodiment of the present invention. As shown by reference numeral 1a, multicolored colored portions 1a are continuously formed.

This multicolored colored portion 1a is colored in a manner that changes the color from the starting end to the ending end of the roll of recording paper 1, for example, from green to yellow to red. In this way, the user can
By looking at the color, you can always tell whether the remaining amount is low or not.

Note that if the length of the recording paper is sufficiently long compared to the amount of work to be done at one time, coloring may be started from a length that is necessary and sufficient to be used for the amount of work at one time. In this way, even if the number of colors is small, the remaining amount can be displayed in detail.゛ [Second Embodiment] Fig. 2 explains the second embodiment of the present invention. In this embodiment, the remaining amount display portions are provided with numbers at regular intervals on the side edge of the roll of recording paper l. 1b is formed.

If such a structure is adopted, the remaining amount can be immediately known by simply reading the numbers on the remaining amount display section 1b.

[Third Embodiment] FIG. 3 illustrates a third embodiment of the present invention, in which remaining amount display portions 1C are formed by codes such as barcodes at predetermined intervals on the side edge of the back surface of the recording paper 1. It is.

When such a code display is used, a reading device 2 is provided as shown in Fig. 4, and the read code is converted into a number, etc. that indicates the remaining amount using the 2-seed conversion table in the storage device 3. This is input into the control device 4 and displayed on the display device 5.
All you have to do is configure it so that it is displayed via .

In addition, in the case where the control device 4 is provided in this way, it can be configured to simply display the remaining amount and cause the recording operation to be stopped or changed.

[Effects] As is clear from the above description, according to the present invention, a remaining amount display section is provided on a part of the surface of the roll-shaped recording paper on which recording information is not recorded. Because of this structure, the user can always know the remaining amount of recording paper, and it does not interfere with recording work.
