Abstract

PURPOSE:To make it possible to set an optimum color density for paper for recording of any kind and quality by a construction wherein a recording element is driven to record a prescribed color pattern when the paper for recording is disposed afresh, and an instruction on adjustment for correcting this color density is transmitted to the recoding element. CONSTITUTION:When rolled paper 1 for recording is disposed afresh, a disposition detecting element 4 drives a recording control element 6, which drives a recording element 2 when a preparation completion signal is received from the recording element 2. Since a drive signal contains an image information on a prescribed color pattern, the recording element 2 records this image on the paper 1 for recording and delivers recorded paper 10 to a color density detecting element 5, which measures a color density and outputs a measured value. In the recording control element 6, a trial drive element 7 receives a fresh disposition signal and the preparation completion signal and output the drive signal, while anoptimum density setting element 8 computes an adjustment value for adjusting the measured density value of the color density detecting element 5 to a prescribed optimum density and communicates it to a density adjustment instructing element 9, which communicates the same to the recording element 2 as a density instruction signal. In confirmity with the density instruction signal, the recording element 2 sets the density for recording thereafter.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a facsimile machine that records image information on a roll of recording paper and outputs the recorded paper.

[Background of the invention]

In recent years, with the spread of facsimile machines, the demand for recording paper, which is a consumable item, has increased. For this reason, recording paper of a wide range of paper qualities is purchased from the nearest stationery store and used, and it is no longer possible to use only the type of recording paper specified by the manufacturer.

[Conventional technology]

Traditionally, this type of facsimile machine has
Alternatively, it has a density adjustment section that can manually adjust the density by checking the color density of the original. However, adjustment of the facsimile device to the optimum density is performed for a designated type and paper quality of recording paper. Therefore, if the paper quality is different from the specified one, the recording will be too dark or too light, so the optimum density is manually adjusted.

[Problem to be solved by the invention]

As mentioned above, conventional facsimile machines adjust the recorded color density to be optimal for the specified recording paper, so when using recording paper other than the specified one, the intermediate optimum density setting will cause the first sheet to Although it is necessary to make trial recordings and manually set the density, it is possible to discover density defects only after setting the recording paper in a predetermined position and receiving it for the first time.However, in the case of roll-shaped recording paper, it is difficult to detect density defects after recording a large amount of received recordings. The problem was that it could be discovered.

The purpose of the present invention is to solve the above-mentioned problems by inspecting the color density of the recorded paper that was first printed and output when the recording paper is placed, and automatically adjusting the recording section to achieve the optimum density. The purpose of the present invention is to provide a facsimile machine that has the following features.

[Means to solve the problem]

A facsimile device according to the present invention records image information on a roll of recording paper and outputs the same, and includes a placement detection unit that detects and notifies new placement of recording paper, and a recording paper that is ejected from the recording unit. a color density detection unit that detects the color density of the recording unit; and a color density detection unit that drives the recording unit to form a predetermined color pattern when the recording paper is placed at a predetermined position in the recording unit upon receiving a notification of new placement from the placement detection unit. At the same time as recording on the recording paper, receiving the color density detected by the color density detection section, instructing the recording section to adjust it to a predetermined optimum density, notifying the recording section of permission to record, and sending a predetermined optimum density adjustment instruction to the above-mentioned arrangement. and a recording control unit that fixes the information until the next new installation notification from the installation detection unit.

[Effect]

The facsimile apparatus according to the above-mentioned means can automatically perform trial recording each time the roll of recording paper is replaced, detect the color density, and set the optimum density.

〔Example〕

Next, a facsimile apparatus according to the present invention will be explained with reference to the drawings.

FIG. 1 is a functional block diagram showing one embodiment of the present invention. In FIG. 1, the facsimile machine transfers recording paper 1 to recording section 2.
The recording paper 1° on which the image information stored in the image information memory section 3 is recorded as a screen is discharged. In the present invention, the facsimile apparatus has a detection section 41, a color density detection section 5, and a recording control section 6, and the recording control section 6 includes a trial driving section 7. It includes an optimum density setting section 8 and a density adjustment instruction section 9.

The placement detection section 4 detects the remaining amount of the roll-shaped recording paper 1, and also treats the change from no recording paper 1 to present as a new placement of the recording paper 1, and sends a new placement signal to the trial drive section. Notify 7. This new placement signal is sent when the presence of paper is detected even if some of the recording paper 1 is used. Color density detection section 5
detects the printing color density of 1° of recorded paper as an absolute value and notifies it to the optimum density setting section 8.

The trial drive unit 7 receives a new placement signal from the placement detection unit 4 and sends a drive signal to the recording unit 2 when it receives a preparation completion signal from the recording unit 2 indicating that the recording paper 1 has been placed and recording preparation has been completed. At the same time, the optimum density setting section 8 is made to erase the conventional setting value and prepare to receive the color density from the color density detection section 5.

When the optimal density setting section 8 receives a notification of color density from the color density detection section 5 in a predetermined procedure according to an instruction from the trial driving section 7, the optimum density setting section 8 automatically sets a predetermined optimum density and sends it to the density adjustment instruction section 9. At the same time, the settings are held until the next instruction from the trial drive section 7 is given. The density adjustment instructing section 9 sets the density setting from the optimum density setting section 8 as an intermediate tone, and transmits the color density adjustment value of light and shade by manual adjustment if necessary to the recording section 2 as a density instruction signal.

The recording section 2 does not accept driving from the image information memory section 3 until it receives the density designation signal after transmitting the preparation completion signal.

Therefore, when the roll-shaped recording paper 1 is re-arranged, in the facsimile apparatus according to this example, the arrangement detection section 4 drives the recording control section 6, waits for a ready signal from the recording section 2, and then starts the recording section 2. Drive. The drive signal not only drives the print recording of the recording section 2, but also includes image information of a predetermined color pattern, so the recording section 2 records this image on the recording paper 1 and sends the recorded paper 1o to the color density detection section. 5, the color density detection unit 5 measures the color density and outputs the measured value.

In the recording control section 6, the trial drive section 7 receives the new installation signal and the ready signal and outputs a drive signal, and the optimum density setting section 8 sets the density measurement value output by the color density detection section 5 to a predetermined optimum density. The adjustment value to be adjusted is calculated and notified to the density adjustment instruction section 9, and the density adjustment instruction section 9 notifies the recording section 2 as a density instruction signal. The recording section 2 sets the density for subsequent recording according to the density instruction signal.

In the above embodiment, the recording control section has been illustrated and described as being divided into functional blocks, but the explanation of block allocation does not limit the present invention as long as they perform the same function.

〔Effect of the invention〕

As explained above, the facsimile apparatus of the present invention has the functions of detecting that recording paper is newly placed and detecting the color density of recorded paper, and when the recording control section newly places recording paper, Since it has a configuration that drives the recording section to record a predetermined color pattern and sends an adjustment instruction to the recording section to correct the color density, the optimal color density can be set for any type and material of recording paper. Effects can be obtained.
