Abstract

(57) [Abstract] [Purpose] To provide a graphic measuring instrument capable of accurately imparting a measured trace on a line to be measured simultaneously with measurement. A casing includes a measuring roller 2 that is rolled while sliding on a measured line L of a figure, and a conversion unit 3 that converts the rolling rotational speed of the measuring roller 2 into its moving length or an amount related thereto. 1, the colorant cartridge 4 is detachably attached to the casing 1, and a communicating thin tube 7 for supplying the colorant to the peripheral surface of the measuring roller 2 is extended to the colorant cartridge 4. It is characterized by that.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention measures the length of a specific member displayed as a figure on a drawing and, if necessary, calculates or integrates quantities related to the measured length, such as actual length, material cost, construction cost, etc. FIG.

[0002]

[Prior art]

 The figure measuring device includes a measuring roller that is rolled while sliding on a measured line of the figure, and a conversion unit that converts the rolling speed of the measuring roller into its moving length or an amount related thereto. A device provided in a casing is well known, and a mechanical type and an electronic type are known as the conversion unit.

However, in the above-described figure measuring device, there is a problem that the measurement management is hindered because there is no measurement mark left on the measured line of the figure after the measurement.

It is conceivable to add a coloring agent applicator to the measuring roller in order to leave a trace of measurement along the measured line, but in this case, the measuring roller is placed on the measured line for measurement. It is difficult to make the applicator slide on the line to be measured with an appropriate pressure in order to give a measured mark while rolling accurately, and the applicator is used to measure the applicator. There arises a problem that the measurement position on the line is not accurately reflected.

[0005]

[Problems to be solved by the device]

 An object of the present invention is to provide a graphic measuring instrument capable of accurately applying a measured mark to a measured line simultaneously with measurement.

[0006]

[Means for Solving the Problems]

 The figure measuring device according to the present invention comprises a measuring roller that is rolled while sliding on a measured line of a figure, and a conversion unit that converts the rolling speed of the measuring roller into its moving length or an amount related thereto. In the figure measuring instrument in which and are provided in the casing, the coloring material cartridge is detachably attached to the casing, and the supply member for supplying the coloring material to the peripheral surface of the measuring roller is extended to the coloring material cartridge. Is characterized by.

[0007]

[Action]

 In the above configuration, the colorant of the required color is supplied from the colorant cartridge to the peripheral surface of the measuring roller via the supply member, and the measuring roller itself is colored on the measured line at the same time as the rolling of the measuring roller on the measured line of the figure. The material is transferred and applied.

The colorant cartridge is exchanged with another color cartridge according to the change of the measurement conditions of the measurer or the like, if necessary. A plurality of colorant cartridges may alternatively be provided in the casing so that they can be used.

【Example】

 FIG. 1 is a sectional view of the main part of the lid of the figure measuring device according to the embodiment of the present invention, in which the measuring roller 2 is rotatably supported at the end of the casing 1 and the measuring roller 2 is rolled inside. A conversion unit 3 is provided for detecting the dynamic rotational speed and converting it into the moving length of the measuring roller 2 or an amount related thereto, and a display unit (not shown) for displaying the output of the conversion unit 3 is provided on the side surface. The coloring material cartridge 4 is detachably mounted inside the cartridge chamber 5 and the coloring material cartridge 4 is colored on the peripheral surface of the measuring roller 2 through the hygroscopic pad 6. A communicating thin tube 7 is extended as a supply member for supplying a charge.

In the figure measuring device having the above-mentioned configuration, the measuring roller 2 is rolled while sliding on the measured line L of the figure, and at the same time, the colorant cartridge 4 communicates with the communication thin tube 7 and the hygroscopic property on the peripheral surface of the measuring roller 2. A coloring material of a required color is supplied through the pad 6 and is transferred and applied onto the line L to be measured by the rolling measuring roller 2 itself.

[0011]

[Effect of device]

 The figure measuring device according to the present invention is configured as described above, and at the same time when the measuring roller itself rolls the colorant onto the measured line on the measured line of the figure, the colorant is transferred and applied. Traces can be accurately applied on the measured line.
