Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mobile object photographing device for photographing objects, characters, etc. moving at high speed, and particularly for determining the finishing order of horse races, bicycle races, boat races, auto races, etc. It is suitable for use in

"Prior Art" Conventionally, as this type of mobile photographing device, the one shown in FIG. 4 is known. FIG. 4 shows a schematic configuration of a mobile object photographing device, and also shows an example in which this mobile object photographing device is applied to determining the finishing order of a horse race. In this figure, the symbol l
is a mobile photographing device (hereinafter abbreviated as photographing device). This photographing device 1 uses an image 3 of an object 2 (in this figure, a race horse, hereinafter referred to as a moving object) moving at high speed.
A photographing mechanism 5 records the image on the film (silver halide film) 4, and the corresponding time data is printed in the printing area 6 on the surface of the film 4 along with the moving object image 3 recorded on the film 4 ( a printing mechanism 7 for imprinting); a printing control section 8 for forming time data to be printed in a printing area 6 on the film surface 4 and controlling the printing procedure of the printing mechanism 7 based on the formed time data; It is roughly composed of:

The dirt floor photographing mechanism 5 is generally composed of a photographing lens 9, a slit plate 10 having a slit lOa provided on the slit surface of the film 4, and a film transport mechanism 11. Further, the printing mechanism 7 has elongated segment-shaped light emitting elements (
The device is generally composed of a segment type display 12 consisting of a combination of a plurality of elements) and an auxiliary optical system 13 that images the display surface of the segment type display 12 onto a film 4. The segment type display 12 is, for example,
4× so that 4-digit numbers can be displayed at once
It consists of a segment type LED display consisting of 7 segments. The auxiliary optical system 13 also includes an imaging lens 14.
and a mirror (or prism) 15.

As a result, when four-digit numerical values are flashed (instantaneous light emission) at one time on the segment type display 12, images of these numerical values are formed on the film 4 and printed. Then, the photographing mechanism 5 and the printing mechanism 7
is housed in the housing I6. Further, the printing control section 8 is controlled by a microcomputer. The print control section 8 and the printing machine PIt7 are connected via an electric cable. As shown in FIG. 4, the photographing device (1) having such a configuration is arranged so that an object image on the goal line (reference line) 17 is formed on the film 4 through the photographing lens 9 and the slit 10a.
Moving object 2 passing film 4 over goal line 17
By moving and rewinding at a speed corresponding to the direction of movement of the moving object 2 and in the opposite direction to the moving direction of the moving object 2, only the image 3 of the moving object that has passed over the goal line 17 is continuously imprinted on the film 4 over time. It will be done. In this case, goal line 1
The image of a stationary object (e.g. background) on 7 is always in slit 1
Since it passes through 0a and reaches the film 4, it is imprinted in a band shape along the moving direction of the film 4, and is not imprinted as an actual shape. Also, at this time, the print control section 8
Based on the printing command from , the printing mechanism 7 flashes each light-emitting element of the segment type display 12 to intermittently display time data on the printing area 6 of the film 4 along with the moving object image 3. I try to take pictures of it. This time data is, for example, the elapsed time from when the moving object 2 starts to when it reaches the goal. Here, the judge visually compares the moving object images 3 imprinted on the developed film 4 to judge the order of arrival of the plurality of moving objects 2 that have passed over the goal line 17. At this time, the judge refers to the time data printed along with the moving object image 3 in order to make the above judgment accurately and quickly.

"Problems to be Solved by the Invention" By the way, in the conventional photographing device 1, the printing mechanism 7 is configured using a segment type display I2 consisting of NX7 segments in order to display an N-digit numerical value. So,
It was unsuitable for human effort in creating more complex character patterns such as kana and kanji.

Furthermore, since a plurality of segment type displays 12 are used, the flash display area becomes large. Therefore, in order to print time data on the film 4 without distortion or blurring, the auxiliary optical system 13 must be configured with an imaging lens 14 whose aberrations have been corrected from the paraxial to the periphery. Therefore, the auxiliary optical system i3 becomes larger and more complicated. This reflected on the entire photographic device, resulting in an expensive and large photographic device l. The present invention has been made in view of the above-mentioned circumstances, and an object of the present invention is to provide a photographing device that can input character patterns such as kana characters and kanji characters in addition to numbers, and can also print clearly. The purpose is Furthermore, it is an object of the present invention to provide an inexpensive and compact photographing apparatus as a whole by making it possible to employ an inexpensive and compact auxiliary optical system.

``Means for Solving the Problems'' The present invention includes a photographing mechanism that records an image of a moving object passing a predetermined reference line on a film running at a speed corresponding to the moving object through a slit, and a point-like light emitting device. multiple elements,
a printing mechanism that prints data on the film in conjunction with the image of the moving object by blinking the plurality of light emitting elements; The above-mentioned problem is solved by providing a print control unit that creates the data to be printed and controls the printing procedure of the printing mechanism based on the created data. The photographing device of the present invention is significantly different from the conventional photographing device described above in that the printing mechanism is constituted by a dot-line display made of a plurality of dot-like light-emitting elements arranged in a line. By the way. In such a photographing device, the printing mechanism is configured using a dot line type display, and the corresponding light emitting elements on the line are simultaneously driven to print.
It is possible to input data consisting of complex character patterns. Furthermore, since it is a dot line type display, the display area is small. Therefore, since the display area is limited to the vicinity of the optical axis, clear printing can be obtained. Further, as the imaging lens of the auxiliary optical system, it is sufficient that the aberrations are corrected only in the vicinity of the optical axis, and as a result, an inexpensive and compact photographing device can be obtained as a whole.

"Example" Embodiments of the present invention will be described in detail below with reference to the drawings.

1 to 3 show an embodiment of the photographing device of the present invention, and FIG. 1 is a diagram showing a schematic configuration of the photographing device of this example,
FIG. 2 is a block diagram showing the configuration of a printing mechanism and a printing control section in this example, and FIG. 3 is an explanatory diagram showing print data according to this example.

In the following figures, the same reference numerals are attached to the same components as those of the above-mentioned conventional example to simplify the explanation. In this photographing device 18, as shown in FIG.
9 is installed at a location where the operator can easily perform data input operations.

As shown in FIG. 2, this print control section I9 is comprised of a data input means 20, a character generator 21, a data processing means 22, and a data output means 25. The data input means 20 is used by an operator to enter print data, control commands, etc., and may be, for example, a keyboard consisting of a numeric keypad and an encoder, a magnetic storage device, or the like.

The print data that the operator inputs from the data input means includes, for example, racetrack name, competition date, race name,
Examples include time display. Control commands input by the operator include designations of flash time, flash period (print dot spacing), and character spacing. The data input means 20 is further provided with a start switch, a reset switch, and a test switch (these are not shown). The start switch is automatically turned on when the moving object (race horse) 2 starts. Further, the character generator 21 has a ROM configuration, and patterns of kanji, kana characters, alphabets, numbers, symbols, etc. are written therein. Further, the data processing means 22 is constituted by a microcomputer having a CPU (central processing unit), ROM and RAM, and the data input means 2
Based on the print data and control commands input from 0, the data processing means 22 reads the corresponding characters from the character generator 21, creates predetermined data, and controls input/output. . The data processing means 22 is connected to the data input means 20, the character generator 21, and the data output means 25 through pass lines.

Further, the data output means 25 transfers the data created in the data processing means 22 to the drive circuit 24 of the printing mechanism 23.
It has a buffer memory to temporarily store the created data. Printing mechanism 2 in this example
In No. 3, a dot-line type LED (light emitting diode) display 26 is used, which is made up of seven dot-shaped light emitting elements arranged in a line. This dot line type LED 26 uses an auxiliary optical system 13 to illuminate the film 4 when the 7 dot light emitting elements flash at once.
The linear pattern 1 is printed (imaged) on the printing area 6 of the printing area 6 in a direction perpendicular to the running direction thereof. The printing mechanism 23 also includes a dot line type LED display 26.
A drive circuit 24 is provided for flashing. This drive circuit 21 consists of 7al switching elements, each switching element is connected to each light emitting element of the dot line type LED display 26 in a one-to-one manner, and
Each switching element of this drive circuit 24 is connected to each of the seven output terminals of the data output means 25! They are connected one to one. Thus, the maximum number of light-emitting elements used for one flash of the dot-line LED display 26 is 7 in one vertical row.
This is a dot display element. and 1 in 5 flashes
It is designed to print characters.

In such a configuration, first, the operating tool makes full use of the data input means 20 to enter, for example, the name of the racecourse, the date of the competition,
Print data such as race name, time display, flash time, flash cycle (print dot interval), character interval, etc.
Input control commands such as time display interval. Human input signals such as print data and control commands are processed by the data processing means 22.
The data processing means 22 sequentially reads corresponding character patterns from the character generator 21 based on this human input signal, and temporarily stores the read character patterns in the buffer memory of the data output means 25. The data output means 22 outputs the character pattern signal temporarily stored in the buffer memory as a flash ON10 F F signal to the printing mechanism according to a control command from the data processing means based on the flash time, flash interval, etc. set and inputted by the operator. 23 drive circuits 24 in sequence. In this way, seven flash 0N10FF signals corresponding to the seven dot light emitting elements in one column are sent to the drive circuit 24 in parallel at once. At this time, the drive circuit 24 turns on only the switching elements that have received the flash ON signal, and thus the corresponding light emitting elements emit a flash. Next, when it is desired to display a time, the start switch of the data input means 20 is turned on as soon as the moving object (race horse) 2 starts, and when the preset time display interval is 0°5 seconds. will be displayed every 0.5 seconds. FIG. 3 shows data D printed on the film 4 in this manner. The determination amount can be easily recognized by visually observing the moving object image 3 and the data D printed on the developed film 4, such as the racetrack name, race name, arrival order, arrival time, etc.

In this way, in the above configuration, the dot line shape,
Since the printing mechanism 23 is configured using the ED display 26,
Kanji and kana characters can be printed. Further, the character spacing and the printing dot spacing can be adjusted freely and easily in accordance with the film speed. Furthermore, since the dot-line LED display 26 is composed of dot-shaped light emitting elements, the display area is small. Therefore, since the display area is limited to the vicinity of the optical axis, clear printing can be obtained. In addition, as an imaging lens used in an auxiliary optical system, it is sufficient if aberrations are corrected only near the optical axis, and such lenses are inexpensive and small, so
In the end, it is possible to obtain an inexpensive and compact photographing device as a whole.

In addition, in the above-mentioned example, the case was described in which the silver halide film 4 was used as the recording medium, but the present invention is not limited to this, and other photosensitive media (such as magneto-optical recording materials) may be used.

Furthermore, in the above example, the case where the printing mechanism 23 is constituted by the dot line type LED display 26 consisting of 7-dot light emitting elements has been described, but the light emitting elements are not limited to 7 dots, and for example, 24 dots can be used. , 32
A dotted one may also be used. In this way, it is possible to obtain much clearer printing, and it is also possible to print several lines at the same time. For example, text data such as racetrack name and race name can be printed on the first line, and the time display can be printed on the second line.
The time mark can be printed on the third line.

Furthermore, in the above example, a case is described in which a dedicated printing area 6 is set on the upper or lower side of the film 4, but this is not limited to this case, and superimposed display on the moving object image 3 You may do so.

Further, in the above example, a case was described in which an LED was used as the display, but the same effect as described above can be obtained even if a plasma display, a fluorescent display, or a semiconductor laser array is used.

"Effects of the Invention" As explained above, the photographing device of the present invention has a photographing mechanism that records an image of a moving object passing a predetermined reference line through a slit on a film traveling at a speed corresponding to the moving object. , comprising a dot-line display consisting of a plurality of dot-like light-emitting elements arranged in a line, and by blinking the plurality of light-emitting elements, data is printed on the film along with the image of the moving body. and a printing side glJ that creates the data to be printed on the film and controls the printing procedure of the printing mechanism based on the created data.
Since it is equipped with a portion, the number of character patterns that can be printed is significantly increased, and clear and high-density printing becomes possible. Furthermore, since it is a dot line type display, the display area is small. Therefore, the performance of the auxiliary optical system is sufficient if aberrations are corrected only in the vicinity of the optical axis, and as a result, the entire apparatus can be made inexpensive and compact.
