(Example)

Preferred embodiments of the present invention are described with reference to the accompanying drawings.

1 is a perspective view showing a cartridge type vehicle driving recorder according to an embodiment of the present invention.

In Fig. 1, reference numeral 1 denotes a box-shaped vehicle driving recorder main body, and 11 denotes a cartridge which receives the recording paper 21 and is inserted into the driving recorder main body 1.

The cartridge 11 includes a case 12 having a recording paper container (not shown) for accommodating the recording paper 21 on its upper surface, and a cover 13 for opening and closing the recording paper container. The case 12 has a front end portion which is substantially arc-shaped in the plan view-a side inserted into the driving recorder body 1-and a V-shaped indicating groove 12A which is formed at approximately the center of its left and right sides near the front end portion of the upper surface of the case. Also have

In the upper surface of the case 12, a recess is formed in a shape corresponding to the recording paper 21, and a rotating table (corresponding to the recording paper holder) (not shown) which holds the circular recording paper 21 on the surface thereof is not formed. Rotatably mounted on the surface. A rotating support shaft (not shown) is provided on the bearing portion of the rotary table, and a centering member 14A (corresponding to the first joint portion) having a recess portion 14B on its upper end is mounted.

When the recording sheet 21 is placed on the rotating table of the cartridge 11, the rotation position of the recording sheet indicates the correct time scale position (not shown) on the recording sheet whose V-shaped indicating groove 12A of the cartridge corresponds to the current time. It is set to.

The cartridge 11 is inserted into the driving recorder main body 1 from the cartridge loading / unloading port 7 and then supported by a lifting frame (not shown) through the cartridge holder to be held at a predetermined information recording position. Until it is moved upwards as indicated by arrow A.

Next, an inner assembly which is assembled inside the driving recorder main body 1 will be described.

As shown in phantom in FIG. 1, the inner assembly has an inner plate 50, a guide pin 60 (corresponding to the second joint), recording needles 18A, 18B, and 18C, and a V-shaped protrusion. Equipment components such as positioning pin 70A.

The inner plate 50 is made of a printed circuit board having a wiring pattern (not shown) formed on its upper surface and equipment parts mounted on its bottom surface. The guide pin 60 is a truncated cone shape that is supported on the bottom surface of the inner plate 50 and sized together with the outer diameter so as to be connected to the recess 14B of the centering member 14A and tapered toward the tip. In the state where the inner plate 50 is installed in the driving recorder main body 1, the guide pin 60 can be connected in the recess 14B of the cartridge 11 held in the information recording position by the lifting frame.

The positioning pin 70A having the V-shaped protrusion is installed on the bottom surface of the inner plate 50, and extends longer than the vertical height of the case of the cartridge 11, case 12, so that the inner plate 50 is driven by the driving recorder main body. It can be connected to the V-shaped indicating groove 12A of the cartridge 11 held in the information recording position by the lifting frame in the state where it is mounted in 1).

As described above, when the cartridge 11 is inserted into the cartridge loading / unloading port 7 with the cover 13 up with the inner assembly and the elevating frame installed in the drive recorder body 1, The cartridge 11 is moved to a position inside the main body 1, and then the guide pin 60 is connected to the recess 14B of the centering member 14A, and the positioning pin 70A having the V-shaped protrusion is V-shaped. It is ascended to the information recording position by the elevating frame until it is connected in the instruction groove 12A.

In this way, the virtual line in Fig. 7 is connected to the V-shaped indicating groove 12A used as the alignment line to set the time for the recording paper and the pin having the V-shaped protrusion is used as the positioning pin 70A. As indicated by the positioning groove 12B formed at the end of the cartridge case in the conventional drive recorder is removed, thereby reducing the size of the cartridge.

The connection of the guide pin 60 into the recess 14B centers the cartridge and the inner assembly, ie the radial direction of the recording paper 21 between the recording paper 21 and the recording needles 18A, 18B, 18C. Perform position alignment with. In addition, the connection between the positioning pin 70A having the V-shaped protrusion and the V-shaped indicating groove 12A coincides with the phase of the cartridge 11 and the inner assembly, that is, the recording paper 21 and the recording needles 18A, 18B. , 18C) in the circumferential direction of the recording sheet 21.

2 is a perspective view of a cartridge type vehicle driving recorder according to another embodiment of the present invention. Fig. 3 is a partial cross-sectional perspective view of the first thrust holding mechanism used in such a cartridge type vehicle recorder. 4 is a cross-sectional view of the first thrust holding mechanism. 5 is a partial cross-sectional perspective view of a second thrust holding mechanism used in a cartridge type vehicle driving recorder. 6 is a cross-sectional view of the second thrust holding mechanism. 7 is a diagram illustrating the present invention for reducing the width of a cartridge.

In Fig. 2, reference numeral 80 denotes a first thrust holding mechanism. The first thrust holding mechanism 80 is used in place of the " positioning pins having V-shaped protrusions " in the vehicle recorder of the first embodiment.

As shown in FIGS. 3 and 4, the first thrust retaining mechanism 80 includes a center pin 80-1, a guide bushing 80-2, and a spring 80-3.

The center pin (80-1) is a shank (80) inserted into the tubular guide bushing in such a way that the thrust moving in the direction of the arrow (B), the V-shaped protrusion (80-1a) suitable for connection with the V-shaped indicating groove (12A) -1c), a pair of arms 80-1 having a locking portion 80-1d inserted into the first hole 50a of the inner plate 50 and locked at its free end on the upper surface of the inner plate 50 1g), and an intermediate bottom portion 80-1e for fixing one end of the spring 80-3. The locking portion 80-1d is provided to maintain the thrust movement of the center pin in the direction of arrow B in a predetermined stroke.

The center pin 80-1 has a radial rotation preventing portion 80-1f inserted into the second hole 50b of the inner plate 50 to prevent radial rotation of the center pin.

The guide bushing 80-2 is made of a tubular material protruding from both the upper and lower surfaces of the inner plate 50, and the center pins 80-1 in the hollow portion allow the shank to perform thrust movement. Accept shank 80-1c.

The spring 80-3 has one end opposed to the middle bottom portion 80-1e of the center pin 80-1 and the other end of which is formed on the lower surface of the inner plate at the portion where the guide bushing 80-2 is formed. It is held against, thus enabling the thrust movement of the shank 80-1c in the direction of arrow B.

Furthermore, as shown in FIGS. 5 and 6, the inner plate also has a second thrust retaining mechanism 90 which enables to perform a thrust movement, which is shown in FIG. 2. A center pin, a guide bushing 80-2, and a spring 80-3 having a bottom surface 80-1b in contact with the top surface of the cartridge at a position near the rear end indicated by " + ". Although this embodiment has two second thrust retaining mechanisms 90, one or more than two may be provided. Although the bottom surface 80-1b is shown flat in FIGS. 5 and 6, the contact surface can be formed in other shapes as long as it contacts the upper surface of the cartridge.

According to the present invention, the size of the overall structure of the vehicle recorder can be reduced by reducing the structure space of the cartridge and the drive recorder body accommodating the cartridge. Furthermore, by reducing the clearance in the Z direction between the cartridge and the cartridge holder to reduce the vertical position change of the cartridge, the vehicle driving recorder can record the information at the correct position on the recording paper by the recording needle.

From the foregoing description of the invention, it will be apparent to those skilled in the art that many changes and modifications can be made without departing from the spirit and scope of the invention as characterized herein.
