Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a seven segment display and a light emitting diode in which information such as setting, operation and processing of various devices and systems is obtained by using a dynamic drive method. The present invention relates to an information collecting device that illuminates and displays information that is displayed on a display device and that is visually checked from a data signal and a timing signal that are displayed on a display device provided in various devices and systems.

(Prior Art) At present, settings, operations, and processes of various devices and systems are displayed on a display so that they can be visually checked as information. There are many systems.

The display includes a digital display and a light emitting diode (hereinafter referred to as "LE") as shown in FIGS.
D ") and those using digital displays and LEDs.

FIG. 4 shows a display 10-1 to be displayed on the digital display 14-1. As shown in FIG. 5, seven lighting segments a, b, c, d, e, f which can be turned on independently are shown. , g is used. This seven segment display 14-3 lights and displays the lighting segments a, b, c, d, e, f, and g.
For example, to represent the number “3”, the lighting segments a,
Turn on b, c, d, g. The digital display 14-1 includes a plurality of such seven-segment displays 14-3. This digital display 14-1 is
It is used for numerical display of various devices and systems.
For example, it is used for displaying a measured value of a measuring device, displaying the number of sheets of a printer or the like, and displaying operating time of various devices and systems.

FIG. 6 shows an indicator 1 displayed by LEDs 15-1 to 15-11.
0-2, setting of various devices and systems for each item,
The operation and processing are indicated by LEDs 15-1 to 15-11.
For example, if 15-8 is lit, it indicates that A3 paper has been used, and if 15-9 is lit, it indicates that A4 paper has been used.

Fig. 7 shows the digital display 14-2 and the LEDs 15-12
10 to 15-17, and a digital display 14-2 for numerical display of various devices and systems.
, The settings, operations, and processing of various devices and systems are indicated by LEDs 15-12 to 15-17.

As described above, there are many displays that indicate the settings, operations, and processes of various devices and systems. The dynamic drive method is often used for lighting the digital display and the LED of these displays. In this dynamic drive method, if a plurality of digits are to be displayed like a digital display, a circuit for displaying the seven segment display is required for the number of digits, which is disadvantageous in terms of the number of parts, mounting space, and the like. It is used to reduce the number of parts. A timing signal is provided to a circuit for lighting one seven-segment display, and a plurality of digits are lit by this one circuit. When a data signal is input to the seven segment display, an instruction as to whether or not to light up is given by a timing signal. By repeating this process for the number of digits on the digital display, it appears as if it is lit continuously. Also, in the case of an LED display, a dynamic drive method may be used similarly to a digital display.

As described above, the operation of various devices and systems,
There are many types of devices and systems with indicators that display settings and processes. The information displayed on this display is
Management and collection are performed by an external personal computer or the like. Therefore, some devices and systems have an external output terminal so that they can be connected to an external device such as a personal computer in advance.
However, the information output from the external output terminal is an output of only information determined at the stage of designing and manufacturing various devices and systems, and not all information displayed on the display is output. In addition, there are many devices and systems that do not have an external output terminal. Therefore, information displayed on a display is read by human eyes and input to a personal computer. However, erroneous input and omission of input are caused, and reliability of the information is reduced. Because of this,
We tried to collect information from CPU (Central Processing Unit) of various devices and systems. However, in recent various devices and systems, there is a strong tendency to reduce the size of the device itself, and a circuit design that accommodates as many functions as possible in a limited space is being performed. Therefore, there is a problem that the arrangement of components is complicated and there is no room for adding a new circuit, and a problem that the circuit cannot be modified because the circuit is dense. Further, the CPU processes a large amount of information at high speed, and the processing timing is very complicated. In this state, in order to output new information, it is necessary to change the processing timing. However, if the processing timing is changed, there is a possibility that the operation of the entire apparatus may be hindered.

Furthermore, since the display is displayed by the dynamic drive method, there is a problem that it cannot be used as information only by extracting a display signal indicating the display.

(Problems to be solved by the problems) As described above, the settings, operations, and processes of various devices and systems are displayed on a display so that they can be visually confirmed as information, and the information displayed on the display is transmitted to an external device. Management and collection are performed by a personal computer or the like. Therefore, some devices and systems have an external output terminal so that they can be connected to an external device such as a personal computer in advance. However, the information output from the external output terminal is an output of only information determined at the stage of designing and manufacturing various devices and systems, and not all information displayed on the display is output. In addition, there are many devices and systems that do not have an external output terminal. Therefore, information displayed on a display is read by human eyes and input to a personal computer. However, erroneous input and omission of input are caused, and reliability of the information is reduced. For this reason, we tried to collect information from CPUs of various devices and systems. But,
2.
