JPH0721465Y2 - Remaining indicator of roll recording paper of recording device - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a remaining amount indicator for displaying the remaining amount of roll recording paper for end recording of a recording device, and provides an easy-to-read indicator. Is.

[Conventional technology]

FIG. 5 schematically shows a general configuration of a conventional sheet remaining amount indicator.

In the conventional display, four LEDs are arranged in a line, for example, and the remaining amount of paper is displayed by the blinking state thereof.

For example, configure LED11, LED12 and LED13 with green LED,
LED14 is used as a red LED, and the green LED group is gradually turned off in the first group according to the reduction of the remaining amount of the paper, and when the paper needs to be used for a predetermined amount and the paper needs to be replaced, the red LED is used. It was configured to turn on LED14. That is, the first
The LED groups 11, 12 and 13 of the group were defined to indicate the degree of decrease in the remaining amount of paper, and the red LED 14 to define the replacement time of roll recording paper.

[Problems to be solved by the invention]

As described above, in the conventional device, since the LED groups are simply arranged side by side, the visual impact is weak and the presence or absence of roll recording paper may not be confirmed at a glance.

The present invention aims to improve this point.

[Means for improving problems]

For this reason, in the present invention, a display panel showing the roll recording paper used for the device as a pattern is provided, and the first group of LEDs for displaying the reduction degree of the roll recording paper are provided on the above-mentioned roll recording paper. The LEDs of the second group are sequentially arranged in the drawer portion, and the LEDs of the second group are provided in the roll portion of the above-described patterned roll recording paper.

[Action]

Corresponding to the stylized roll recording paper display panel,
Since the LEDs of the first and second groups are made to blink, the remaining amount of paper can be checked at a glance.

〔Example〕

As schematically shown in the first state of FIG. 3, a remaining amount display panel (broken line in the figure) that is a roll recording sheet used in the device is prepared. The first group LED is arranged on the roll recording paper pull-out portion of this display panel, and the second group LED is arranged on the roll portion.

FIG. 1 is a circuit configuration diagram showing one embodiment of the first group and second group LEDs arranged on these display panels. In the figure, S
1, S2 and S3 are switches that are turned on / off according to the reduction of the roll recording paper used in the apparatus body.

As shown in FIG. 1, when the switches S1, S2, and S3 are all on, that is, when there is sufficient recording paper, the first group
All LED1 lights up, and similarly, the second group LED2 also has the first
All LED groups 21, 22, 23, 24 and 25 belonging to the color are lit. At this time, the LED 26 belonging to the second color of the second group LED is
It is turned off by the NOT circuit 31 (first state in FIG. 3).

When the first switch is turned off, that is, when the remaining amount of paper reaches the second decreasing stage, only the LED 11 at the left end of the first group LED1 in the figure is turned off, and the others are the same as the previous state. The second state in FIG. 3).

Similarly, when the S1 and S2 switches are off, the remaining paper amount is the third
This indicates that the reduction stage has been reached, and the two LEDs 11 and 12 of the first group LED 1 are turned off. Second group LED2 is the same as above
The color LEDs 21, 22, 23, 24, and 25 are lit up, and it also informs that there is sufficient paper remaining (3rd
(The third state in the figure).

When the switches S1, S2, and S3 are all off, that is, when the roll recording paper is about to be replaced, the first
All the LEDs belonging to the first color of the group LED1 and the second group LED2 are turned off, and only the LEDs 26 belonging to the second color of the second group LED2 are turned on to notify that it is time to replace the paper.

FIG. 2 shows an arrangement row of LEDs of the second group shown in FIG. 1. Five LEDs belonging to the first color and LEDs 1 belonging to the second color are shown.
It is composed of individual pieces.

As shown in FIG. 3, the LED groups of the first and second groups notify the decrease state of the paper and the replacement time.

Each corresponds to the off state of the switch groups S1, S2 and S3 shown in FIG.

Since the second group of LEDs, which is composed of a plurality of LEDs, is arranged in one rectangular area (FIG. 2), its size becomes large as shown in FIG. This point also promotes legibility (you can grasp the image of roll paper).

FIG. 4 shows a second embodiment of the present invention.
It is configured such that the LED2 belonging to the first color can be turned on and off by the control circuit.

The device control circuit 4 has a counter (not shown) for counting how much the final recording roll recording paper is pulled out, and both the first and second switches S1 and S2 shown in FIG. 4 are turned off. Next, the recording paper is in the third decreasing state (see FIG.
When the above state is reached, counting of the counter is started.
Then, each time the count value of the counter reaches a predetermined amount, the lighting of the LEDs belonging to the first color of the second group is gradually increased or decreased.

Since the control circuit controls the overall operation of the device, the second
It is possible to know how much the remaining amount of paper is in the reduced state of. By subtracting with the above counter, you can know the state of the approximate remaining amount,
By further increasing or decreasing the number of lights of the LEDs of the first color of the second group LEDs, it is possible to display a more detailed remaining state.

[Effect of device]

As described above, according to the present invention, it is possible to provide an easily visible remaining amount indicator.
