Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual scanning recording apparatus for recording information such as characters and symbols on a recording material such as a book, a document or a drawing by manual scanning.

[Prior Art] In recent years, various recording apparatuses such as an inkjet printer for recording information such as characters on a sheet such as a recording sheet have been developed. However, conventionally, in this type of apparatus, since automatic scanning is generally used to feed a recording sheet or recording head by a machine, it is not possible to record characters or the like on a bound book or document or a large-sized design drawing. It was

So, remove the paper feed mechanism and the print cover,
Recording element, recording synchronization signal generator, recording data control circuit,
Recently, a large number of handy type manual scanning type recording devices in which a recording element drive circuit and the like are incorporated have been proposed and developed.

[Problems to be Solved by the Invention] However, since the conventional manual scanning type recording apparatus as described above does not have means for detecting the recording position, the user can roughly estimate the position by pointing. There was no choice but to put on the recording device and execute recording. So, for example, when trying to print data in a table,
In the conventional manual scanning recording device, along the vertical ruled line of the table,
It was very difficult to print out the data neatly. It is also possible to convert the position of a ruled line or the like into a distance from the recording start point to create recording data so that the ruled line and the recorded information do not overlap, but in the manual scanning type recording device, Since the start position of the print scan is left to the manual operation of the user and an error may occur and the print position may shift, it is difficult to accurately control the print position. Further, since the scanning is also manually performed by the user, it is possible that the printing position may be displaced in the scanning over a relatively long distance, and it is difficult to perform printing so as not to overlap the ruled lines. .

The present invention eliminates the above-mentioned drawbacks, and when recording at a specified position on a table or the like, data can be neatly arranged and recorded along a reference line such as a vertical ruled line of the table without overlapping. An object is to provide a scanning recording device.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a signal generating means for generating a synchronization signal for each predetermined scanning distance corresponding to the scanning distance of manual scanning, and the synchronization signal. In a manual scanning type recording apparatus including a recording unit that drives a recording head to perform recording according to the above, a position detecting unit that detects a reference line or a reference point on a recording material, and a reference line by the position detecting unit. Alternatively, a recording position control unit that counts a predetermined number of the synchronization signals after the reference point is detected and starts recording by the recording head is provided.

Further, the present invention, as one form thereof, can be characterized in that the position detecting means comprises a reflection type photodetector.

[Operation] In the present invention, means for detecting a reference line or a reference point on the recording material is provided, and control is performed so that recording is started after scanning a predetermined amount after detecting a ruled line or the like serving as a reference. Recording can be started from a position where recorded information does not overlap ruled lines.

Therefore, in the present invention, in a manual scanning type recording apparatus in which an error occurs in the scanning start position depending on the user, when recording is performed at a specified position of a table or the like, the ruled line of the table or the like does not overlap and the ruled line does not overlap. It is possible to record the data neatly arranged along the line.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

 FIG. 1 shows the basic configuration of the embodiment of the present invention.

In the figure, a is a signal generating means, and when recording information such as characters on a recording material by manual scanning,
A number of synchronization signals corresponding to the scanning distance of the manual scanning are generated.

Reference numeral c denotes a recording position control means, which controls the recording means d to start the information recording operation after counting the predetermined number of pulses of the synchronizing signal of the signal generating means a from the generation of the position detection signal of the position detection means b.

Here, when nothing is printed on the paper surface of the paper P and it remains in a white state, the light is reflected on the paper surface and enters the phototransistor PTr, thereby turning on the phototransistor PTr, and the signal STROBE2 It becomes “L” (low level). On the other hand, when there are lines or characters printed on the paper P, the light is not reflected, the phototransistor PTr is turned off, and the signal STROBE2 becomes "H" (high level).

FIG. 9 shows a control procedure of the microcomputer MPU of FIG. 6 which performs processing based on the above timing chart. Next, the flowchart of FIG. 9 and FIGS. 7 and 8
The operation of the embodiment of the present invention will be described in detail with reference to the timing chart of the drawing.

First, the contents of the internal counter N are cleared (steps S1 and S2), and it is determined whether the operation signal STROBE3 is "H".
As shown in FIG. 7, when the operation switch SW is OFF, the operation signal STROBE3 remains "H". Therefore, at this time, the microcomputer MPU detects "H" of the signal STROBE3 (step S3) and waits for the input of the synchronization signal STROBE1 (step S4). When "H" of the synchronization signal STROBE1 is input, serial data transfer of the synchronization signal CLK and the recording data signal DATA is started (step S9). The print data signal DATA (D _{0 to} D ₇ ) serially transferred is converted into parallel data by the shift register in the manual scanning printing apparatus control integrated circuit GA, and the parallel data is 8

The above process is repeated until the data DATA stored in the print data buffer in U is finished (step S10), and after the reading of the data DATA is finished, the above-mentioned operation of the manual scanning type record is finished (step S11). ).

On the other hand, when the operation switch SW is turned on, the operation signal STROBE3 changes to "L" as shown in FIG. As a result, a negative determination is made in step S3 described above, and a state in which the recording position detection signal STROBE2 is awaited (step S3) is entered.
Five). When "H" of the recording position detection signal STROBE2 is input, the recording synchronization signal STROBE1 is in a state of waiting for a predetermined signal input α times (steps S6, S7, S8). This waiting is to prevent the recording from overlapping the ruled line when the recording operation is performed immediately after detecting the ruled line of the table or the like.
After waiting for the recording synchronization signal STROBE1 to be input α times, data transfer is started (step S9). Thereafter, similarly to the above-described processing in the case of FIG. 7, the processing operation of steps S10 and S11 is proceeded to, and the operation of the manual scanning recording of the embodiment of the present invention is finished.

By controlling to start the recording, the recording can be started from the position where the recorded information does not overlap the ruled line or the like.

Therefore, according to the present invention, in the manual scanning type recording apparatus in which the scanning start position causes an error depending on the user,
When recording is performed at a specified position on a table or the like, the data can be neatly arranged and recorded along the ruled line without overlapping the ruled line on the table or the like.
