In this state, the user operates the operation knobs 60, 61, 63, and 64 to set the time at that time while confirming the display on the display section 67 through the confirmation window 66. When the shaft 5 is pushed down by grasping the handles 6, 7 of the operation unit 4, the pushing force is reduced by the stopper 31, the spring 32, and the collar 28.
It is transmitted to the elevating frames 25, 26 via and, and lowers the elevating frames 25, 26 against the force of the spring 27. Then, as shown in FIGS. 9 to 11, the horizontal portions at the lower ends of the rubber belts 46 to 49 project below the lower end openings 23 and 24 of the base frame 21, respectively, hit the pigment pads 101, and the printing surface thereof. Pigment such as chalk powder adheres to the surface. Rubber belt
If 46-49 hits pigment bad 101, lift frame
25 and 26 cannot descend any further. Therefore, when the shaft 5 is pushed down thereafter, the spring 32 fitted on the shaft 5 is compressed to absorb the pushing down stroke.

When the shaft 5 is pushed down in this way, the spring 80 interposed between the lower end of the shaft 5 and the bottom plate 74 of the concave portion 71 of the base frame 21 due to the pushing force.
However, part of the pressing force is transmitted to the marking line printing member 72 via the spring 81 and the connecting bar 75. As a result, the marked line printed body 72 protrudes below the concave portion 71 as shown in FIG. 10, and hits the pigment pad 102 so that the pigment adheres to the printing surface. By hitting the print pad 101, the marked line printed body 72 cannot be further lowered, but when the shaft 5 is pressed down thereafter, the spring 81 is compressed to absorb the pressing down stroke.

When the shaft 5 is depressed, the bracket 85 is similarly lowered, and its pin 89 engages with the oblong oblong hole 91 of the support 86. Then, the support
As the pin 88 fits into the horizontal elongated hole 90, the pin 86 is eventually pushed forward, and projects forward through the opening 87 of the base frame 21. As a result, the side printing body 93 hits the pigment pad 103, and the pigment adheres to the printing surface.

As described above, the lateral printing body 93 is
, The response at that time returns to the handles 6 and 7, thereby releasing the pressing force on the shaft 5. Then, the shaft 5 is pushed up to the original upper position by the action of the springs 27, 80, and the printing bodies 45, 72,
93 is stored in the base frame 21 and its concave portion 71 as before with the pigment adhered thereto as described above.

Therefore, as shown in FIG. 1 and FIGS. 12 to 14, the cover 97 is opened, the handles 6 and 7 are held, and the apparatus 1 is moved to the position on the road surface 105 where printing is to be performed. The base frame 21 of the main body 3 is placed at that position. At this time, the time stamp 45 is housed inside the basic frame 21 as described above, and the marked line stamp 72 is
When the apparatus 1 is moved to that position, the printed bodies 45 and 72 come into contact with the road surface, causing the pigments that have adhered to the surface to fall off, or on the road surface other than the position where printing should be performed. 105 can be prevented from being stained by the detachment of the pigment. Further, when the apparatus 1 is moved, it is possible to prevent the printing bodies 45 and 72 from being damaged by the projections on the road surface 105.

As shown in FIGS. 15 to 17, when the enforcement of the parking violation is performed, the base of the apparatus 1 is placed at that position so as to be printed on the road surface 105 near the tire 10 of the parked automobile. The frame 21 is placed, and in this state, the shafts 5 are pushed down by operating the handles 6, 7 again. Then, as shown in the figure, the marking line printing body 72 and the time printing body
The 45 rubber belts 46 to 49 are pressed against the road surface 105, and FIG.
As shown in the figure, the marking line 12 and the time arithmetic numeral 13 are printed. In addition, the support 86 protrudes forward from the opening 87 of the base frame 21, and the lateral print body 93 made of rubber contacts the side surface of the tire 10. At this time, since the side print body 93 has a plurality of cuts 95 formed on the back surface thereof, the side print body 93 is easily curved along the curve of the outer surface of the tire 10, and the curved portion enters the gap 94. . As a result, as shown in FIG.
The marking line 11 is also reliably printed on the side surface of.

When the printing is completed, the force of pushing down the shaft by the handles 5, 6 is released. Then, each printed body
45, 72 and 93 are the same as the base frame 21 and the recess 71 thereof.
Is housed inside. Therefore, from the printing position, the device 1
By closing the cover 97 away from the printer, the printing operation is completed. Therefore, according to the present apparatus 1, printing on the road surface 105 can be performed only by operating the handles 6, 7 of the operation unit 4, and the work in the posture leaning down on the road is not required.

As described above, since the lifting frames 25 and 26 can be independently raised and lowered in the base frame 21, it is possible to cope with the case where the road surface 105 is not flat.
That is, as shown in FIG. 18, when there is a step or the like between the position corresponding to the lifting frame 25 on the road surface 105 and the position corresponding to the lifting frame 26, when the shaft 5 is pushed down, the lifting frame at the higher position is first 25 rubber belts
Printing is performed by contacting the road surface 105 with 46 and 47. And
When the shaft 5 is further depressed from this state, the elevating frame 25 remains pressed by the one end 29 of the collar 28, but the elevating frame 26 is further depressed by the other end 30 of the collar 28, and The rubber belts 48 and 49 come into contact with the lower position. This allows the rubber belt 46
All of ~ 49 come into contact with the road surface 105, and the required time is printed. Similarly, the marking line is printed by the marking line printing member 72.

At this time, as described above, the lifting frame 25,
26 and upper and lower bars 35 and 41 form a parallel link. The lower portions of the lifting frames 25 and 26 are accommodated in the box-shaped base frame 21, and the stoppers 4 of the first bar 35
Since the positions of the upper parts of the lifting frames 25, 26 are regulated by the 0, 40, the positions of the lifting frames 25, 26
Even if such a step is present, 26 is maintained in a state of maintaining the vertical posture. Therefore, all arithmetic numerals for indicating the time are clearly printed on the road surface 105.
