Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention uses a motor to control a document table used for placing a document in inputting work for a word processor, a computer, etc. The present invention relates to a document table which is powered by a motor or the like.

[Conventional technology]

Conventionally, when driving the cursor on the document table, the cursor ftl! can be moved by simply operating a switch or the like.・Some devices are known that have a one-line advance mechanism that not only lowers the cursor but also moves the cursor by one line with a single switch operation.

This one-line feed mechanism uses a timer to operate the motor for a preset time, or uses a pulse motor or a motor with a pulse generator to operate the motor for a preset number of pulses. It is composed of

[Problem that the invention seeks to solve]

To use this one line feed mechanism, it is necessary to set the feed amount for one line. In the mechanism using the above timer, this setting must be done by trial and error, and when setting by the number of pulses mentioned above, if the line spacing is known, it can be easily set using that value. However, if the line spacing is unknown, trial and error is still required. When setting the parameters by trial and error, if the setting values are not accurate, errors will accumulate as you repeatedly advance one line, and the cursor instructions will become unclear, so the settings must be made precisely. , it takes a lot of effort and time.

The present invention has been devised for the purpose of enabling the above setting to be performed accurately and easily even when the line spacing is unknown.

[Means for solving problems]

The document table of the present invention uses one section, not one line, of the document to set the feed amount of one line, calculates the interval between the top line and the bottom line of this section, and calculates the total number of lines in this section. The feed amount per line is calculated by inputting and dividing this interval by the number of lines.

That is, the present invention includes a base plate on which a document is placed, a cursor that indicates one line of the document on the base plate, and a motor that operates on a rise/lower switch to raise or lower the cursor.
A movement amount detector detects the amount of movement of the cursor, move the cursor to the top line of a passage in the manuscript, operate setting switch 1, move the cursor to the bottom line of the passage in the manuscript, and operate the other setting switches. By doing so, an interval detector that obtains the interval between the sections using the movement amount detector, an output of a line number setting switch that sets the total number of lines of the section of the manuscript, and an output of the interval detector, This document table has a calculation device that calculates the Φ interval per line, and a one-line feed device that moves a cursor by one line in response to the output of the calculation device by operating a one-line feed switch.

〔Example〕

Embodiments illustrating the present invention will be specifically described below.

In this document table 10, a document 12 is placed on the table top 1,
It is held by a magnet 13. A cursor 14 extends on the base plate 11 and indicates one line of the original 12. A cursor holder 15 that supports this cursor 14 is threadedly engaged with a screw shaft 16 extending vertically on the back surface of the base plate 11, and this screw shaft 16 is connected to a pulse motor 18 via a limit clutch 17. Therefore, the rotation of the pulse motor 18 causes the cursor 14 to rise and fall. A fine adjustment dial 19 is provided at the lower end of the screw shaft 16, and a limit clutch 17 is provided.
The cursor 14 can be moved by sliding it to rotate the screw shaft 16. A control section 21 containing a microcomputer 20 is provided at the bottom of the base plate 11, and on its surface there are push buttons/switches such as a rise switch 22, a fall switch 23, a setting switch 24, 25, a line advance switch 26, and a rotation switch. A line number setting switch 27 consisting of a switch is provided.

The control [11m 21 microcomputer 20 has
The program realizes the device and mechanism shown in FIG. That is, a pulse generator 28 is provided, and when the up switch 22 and the down switch 23 are operated, pulses are generated, the pulse motor 18 is rotated forward and backward, and the cursor 14 is moved up and down. The output of the pulse generator 28 is simultaneously sent to a movement amount detector 29 consisting of an up/down counter, where the pulses are counted and the movement t'lr of the cursor 14 can be detected. This movement amount detector 29 is reset by operating the setting switch 24, and the interval detector 30, which is a switch device, is activated by operating another setting switch 25, and the output of the movement amount detector 29 at this time is calculated. The data is transferred to the device 31. That is, when the cursor 14fe is placed on the top line of a section of the manuscript 12 and the setting switch 24 is operated, and then the cursor 14 is placed on the bottom line and the setting switch 25 is operated, the size of the interval of this section is sent to the calculation device 31. It will be done. The calculation device 31 divides the size of the interval sent from the interval detector 30 by the total number of lines of this section sent from the line number setting switch, calculates the interval per line, and divides the result into one line.

Send to 2. By operating the one-line feed switch 26 of the one-line feed device 32i, a command is sent to the pulse generator 28 to generate a pulse that moves the cursor 14 by an interval of one line.

Since this manuscript table 10 has the above configuration, select a passage of the manuscript 12, set its total number of lines with the line number setting switch 27, move the cursor 14 to the top line and bottom line, and press the setting switch 24.25. By operating , the feed amount per line is set, and thereafter, each time the line feed switch 26 is operated, the cursor 14 is moved by one line.

Note that the setting operation can be done not only by setting the top line of a section first and then the bottom line, but also by setting the bottom line first, or by setting either the top line or the bottom line first. It goes without saying that it is also possible to allow the settings to be made.

In the above embodiment, each device and mechanism of the control section was configured by a microcomputer program, but it is of course possible to configure it by a logic circuit, and various program configurations can be used. Therefore, it is sufficient that each device such as a movement amount detector exists as a function in the program.

Furthermore, the drive mechanism for the cursor is optional, and in addition to the Mohals motor as the drive source, a motor with a pulse generator or a combination of a cursor position detector and a motor may be used.
It may also be operated by closed loop control. At this time, as the movement amount detector, in addition to an up/down counter, a device that detects the absolute position of the cursor and calculates a difference in position due to movement can be used.

〔Effect of the invention〕

As is clear from the above, when setting the feed amount for one line with the document table of the present invention, instead of setting the line spacing directly, the - section is selected, the spacing for this entire section is set, and the calculation is performed. Since the 91-line interval is calculated, the feed amount per line will be accurate even if there is some error in the cursor position at the time of setting. Therefore, setting operations can be easily performed, and even when the cursor is used, the cursor instruction will be accurate even if one line is repeatedly moved.
