[Embodiments of the invention]

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 2 is a schematic configuration diagram of the embodiment device 1t, and FIG. 3 is a diagram schematically showing its essential tels'Fi'7 configuration.

In the figure, reference numeral 11 denotes a line sensor, which has a structure in which, for example, an optical sensor array is arranged in one direction, and this is the line direction. This line sensor 11 is attached to the probe body 12 with its imaging input surface facing downward, and is connected to a device body and a control device 13 (not shown). In the figure, reference numeral 14 denotes a grip section attached to the glove body 12, and when the glove body 12 is moved by gripping this grip section 14, the line sensor 11 can take an image by itself. It has become.

In the glove body 12, a rolling element guide 15 consisting of a roller is provided in the rotating inner plug so that the line direction of the 2-in sensor 11 and the rotation axis are parallel to each other. As shown in FIG. 3, this rolling element guide (roller) 15 is provided with its peripheral surface slightly protruding from the line sensor 11, and is rolled with its surface in contact with the image surface 16. . Since the rotation direction of the rolling element guide 150 is regular, the probe body 12 equipped with the line sensor 11 can be guided only in a direction perpendicular to the line direction of the line sensor 11 with respect to the image plane 16. It is designed to be used as αII.

On the other hand, 1) the rotation axis of the rolling element guide 15 described in 11 has a distance of 1 V;
ic Ill > Rotary encoder 1 as two devices
7 are arranged in succession. This rotary encoder 17 has a 77rlS in which the rolling element guide 15 rotates by a predetermined angle.
In other words, each time the line sensor 11 is moved by a predetermined ratio i'#la with respect to the image plane 16, a signal is generated and is given to the control device 13. 13 inputs the above signal and controls the input timing of both prizes by the line sensor 11. Therefore, each time the line sensor 11 is moved a predetermined distance with respect to the image plane 16, the line sensor 11 inputs the above-mentioned No. 9 pulse signal. 1□ sequentially across one line
No. 1] tli'J is controlled to input data. Further, the control device 13 detects the moving speed of the line sensor 11 from the input interval of the notrus signal. Then, the moving speed is compared with the image reading operation speed of the line sensor 11, and information indicating whether the moving speed is appropriate or not is displayed via a display zs'f consisting of blue, yellow, and red, for example. ing.

According to the device configured in this way, if the glove body 12 is moved at a speed that is sufficiently compatible with the reading speed of the line sensor 11 in accordance with the information shown on the display 18, the movement of the glove body 12 can be completed. Predetermined moving distance P regardless of speed
i11. At each time, the line sensor 11 reads the image line by line. Therefore, the input image has the line width of the line sensor 11 and is obtained at every 12〆 intervals, and its resolution can be made sufficiently high. Moreover, as described above, since it is not affected by the moving speed of the two-in sensor 1, an image can always be accurately obtained line by line at every predetermined moving distance, so it is easy to handle and highly practical. Further, the device configuration is simple and can be realized at low cost. In addition, according to this device, it is easy to input only the desired image part, and the direction of movement of the mover of the glove body 12 is easily and effectively regulated when making it yourself. Effects such as high operational reliability can also be achieved.

In history, the reliability of the image input can be increased by using the above-mentioned movement speed notifications together.
It improves 1774 times. Moreover, since the image input is controlled in this way, the tube can be extremely effective without causing any distortion in the input image.

FIG. 4 shows another embodiment of the present invention, in which a 70-lobed main body 12 incorporating a line sensor 11 is inserted into a frame 21, and a groove 22 provided in this frame 21 is guided. As such, it can only be moved in one direction. The position of the probe body 12 is detected by a position fj detector 23 provided at the lt1 portion of the frame 21.

Furthermore, FIG. 5 shows guides 4 to 2 provided parallel to the base 24.
5th and 25b, the glove body 12 is movable in only one direction.

A so-called pantograph-like link mechanism 26 is also provided, resulting in a four-back configuration that maintains the parallel movement of the glove body 12 in one direction. Incidentally, it is also possible to adopt a configuration including only either the link mechanism 26' or the guide rods 25a and 25b.

However, in this case, for example, a rotary encoder may be installed on the base 24, a string may be hung between the rotary encoder and the glove body 12, and the position of the glove body 120 may be detected from the winding length of the string. Bye.

Even if the apparatus is configured as shown in FIG. 4 or FIG. 5, the same effects as in the previous embodiment can be achieved.

Note that the present invention is not limited to the above embodiments. For example, it is also possible to use wheels as rolling element guides. Also, it is of course possible to use other distance measuring devices in place of the rotary encoder. Furthermore, line sensor 1
1 is not limited to a single line type, but may be a multiple line type. The shrub invention can be modified and implemented without departing from its gist.
