Abstract

PURPOSE:To enable a recording paper to be speedily replaced without need for checking a manual each time of the replacement, by providing qb means for detecting that the residual amount of a recording paper is small, and a means for storing required information. CONSTITUTION:A thermal head 2 is connected to a CPU 8 for controlling the recorder. The CPU 8 is connected to an interface 10 for receiving data from an input device and transferring a signal to the recorder. On the back side of a recorder 1 is provided a sensor 4, which detects a black band 7 provided on the back side of the paper 1, thereby detecting that the residual amount of the paper is reduced. Information which is required when the residual amount of the paper is reduced and which can not originally known without checking a manual, e.g., the method of replacing the recording paper, an indication of run-out of the paper or where to order the recording paper, is stored in a memory 9. On receiving a signal from the sensor 4, the CPU 18 reads the required information from the memory 9, and sends it to the thermal head 2 to record it on the recording paper 1.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device, and particularly to a recording device that can detect when a small amount of recording paper remains.

It is something.

[Prior Art] Traditionally, calculators, facsimile machines, etc. often use rolls of recording paper, and as recording continues, when it is detected that there is no recording paper, a display or warning that there is no recording paper is displayed. Generally, the operator replaces the recording paper according to the instructions in the manual.

[Problems to be Solved by the Invention] In such conventional recording devices, when the remaining amount of recording paper becomes low, the operator simply displays that there is no recording paper. In many cases, users had to refer to the manual and replace the recording paper each time, which was a hassle.

This is especially true when a plurality of recording apparatuses with different recording paper exchange methods are used simultaneously.

Therefore, the present invention was made to solve these problems, and provides a recording device that can obtain necessary information when the amount of recording paper remaining in the recording device becomes small using a simple method. The purpose is to provide

[Means for Solving the Problems] In order to solve these problems, the present invention provides a means for detecting when the remaining amount of recording paper has become small, and a means for detecting when the remaining amount of recording paper has become small. A configuration is adopted in which the information stored in the storage device is read out and recorded on recording paper when it is detected that the remaining amount is low.

[Function] With such a configuration, when the remaining amount of recording paper becomes small, a signal is output, and the information stored in the storage means that is required when the remaining amount is small is read out. It is recorded on the remaining recording paper. This allows the operator to instantly obtain necessary information such as how to replace the chart paper, whether there is any paper remaining, where to order the chart paper, etc., and avoids the hassle of having to read the manual each time. .

[Example 1] Hereinafter, the present invention will be described in detail according to an example shown in the drawings. In the embodiment shown in FIG. 1, the recording apparatus is constructed, for example, as a thermal recording apparatus, and the recording paper 1 is fed through a platen roller 3, and a thermal head 2 performs printing. The thermal head 2 is connected to a CPU 8 that controls the recording device. An interface IO is also connected to this CPU 8, which receives data from an input device and passes signals to a recording device. Further, a sensor 4 is provided on the back side of the recording paper l, for example, and this sensor detects, for example, a black band 7 provided on the back side of the recording paper l as shown in FIG. Detect what has happened. The memory 9 stores information that is required when there is a small amount left, such as information on how to replace the recording paper, an indication that there is no recording paper, or where to order the recording paper, which would otherwise be difficult to understand without looking at the manual. Then, CPU8 is
When receiving a signal from the sensor 4, it is configured to read out necessary information stored in the memory 9, send it to the thermal head 2, and record it on the recording paper 1.

Next, the operation of the device configured in this way will be explained. Normally, character data and image data are input from the outside via the interface 10, and the CPU 8 is used as a thermal head! The thermal head 2 records one line in the main scanning direction according to the recording command, and the platen roller 3 feeds one line in the sub-scanning direction to record on the recording paper l (as shown in Fig. 5). Step S
L, S2). Subsequently, in step S3, it is determined whether the remaining amount of recording paper is small. If there is enough recording paper, the process returns to steps St and S2 to continue recording. On the other hand, the second
When the remaining amount of recording paper becomes small as shown in the figure, the sensor 4 installed on the back side of the recording paper 1 detects the black band 7 formed on the back side as shown in FIG. detect,
Detects when the remaining amount of recording paper is low. At this time the third
As shown in the figure, after the recording on the page 5 is completed, information that is required when there is a small amount of remaining page 6, such as a recording paper replacement method, etc., is read out from the memory 9, and the remaining page 6 is read out from the memory 9. page 6 (step S4). Subsequently, in step S5, the recording paper is replaced according to the replacement method recorded on the remaining amount page 6, and the original state is restored.

In the above example, the recording device is a thermal printer, but it is not limited to this and can be applied to other printers, such as impact printers. This also applies to devices that use

[Effect of the invention 1 As explained above, according to the present invention, when it is detected that the remaining amount of recording paper is low, the necessary information stored in the storage means is read out and recorded on the recording paper. Therefore, for example, when replacing the recording paper, it is possible to quickly and easily replace the recording paper without consulting the manual each time.

[Brief explanation of the drawing]

Each figure explains one embodiment of the present invention. Figure 1 is a block diagram showing the overall configuration, Figure 2 is an explanatory diagram when the remaining amount of recording paper becomes small, and Figure 3 is an illustration of an example of the present invention. FIG. 4 is an explanatory diagram showing the recording state as seen from arrow A in FIG. 2, FIG. 4 is an explanatory diagram of the recording paper when viewed from direction B in FIG. 2, and FIG. 5 is a flowchart diagram showing the flow of control. .

Claims (1)

[Claims] 1) A means for detecting that the remaining amount of recording paper has become small and a means for storing information required when the remaining amount of recording paper has become small are provided. A recording device characterized in that, when it is detected that the amount has decreased, information stored in a storage means is read out and recorded on recording paper. 2) The recording apparatus according to claim 1, wherein the information required when the remaining amount becomes small is information indicating a method for replacing the recording paper or that there is no remaining recording paper.
