DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a tachograph reading device used for reading a tachograph recording sheet for recording a running state of a vehicle.

(Prior Art) A tachograph device is used as a device for recording a running state of a commercial vehicle such as a sightseeing bus or a truck, a driver, an engine rotation speed, and the like. This tachograph device
A disc-shaped tachograph recording sheet is held on a recording disc, and while the disc is rotated at a prescribed speed, traveling speed, traveling distance, traveling /
It is designed to record a diagram relating to the status classification of stoppages.

Applicant's previous application for Japanese Utility Model Application No. 1-54712
No. 144715) discloses a tachograph reading device suitable for application to a reading / analyzing system for fully automatically reading and analyzing a recording sheet, which has conventionally been done manually. According to this tachograph reading device, a recording sheet to be read and a weight body placed on the reading sheet are automatically conveyed onto a holding table, and then a two-dimensional image is captured as the holding table rotates.

(Problems to be Solved by the Invention) In the tachograph reader according to the above-mentioned prior application, a recording sheet to be read and a weight body placed on the reading sheet are automatically conveyed to a holding table, and the read recording sheet is read. The weight and the weight are automatically removed from the holding table.

However, in a small-scale system with a small number of sheets to be read, it may be more economical to carry out and remove the recording sheet and the weight manually rather than automatically for the reading in the previous stage of analysis. What is needed is an efficient reader in a semi-automatic system.

(Means for Solving the Problem) A tachograph reader according to the present invention includes a plate-shaped holding base made of a transparent material for holding a tachograph recording sheet in an inverted state, and a tachograph recording sheet interposed on the holding base. A weight body to be placed and a mechanism for transporting and removing the weight body by manual operation of transporting the weight body to the holding base and removing it from the holding base, and only when the weight body is placed on the holding base. A sub-scanning rotating mechanism for rotating the holding table at a predetermined speed; and an installation section provided on the back side of the holding table. And an image pickup mechanism for reading an image of the surface of the tachograph recording sheet which is rotating with this rotation as two-dimensional image data through this holding table, and is configured to realize efficient conveyance and removal of the weight body. .

According to an embodiment of the present invention, the weight conveying / removing mechanism is shared with a dustproof lid which is opened and closed above the holding table, so that the weight can be transported more efficiently. It is designed to be practical for removal and use.

Hereinafter, the operation of the present invention will be described in detail with reference to embodiments.

(Embodiment) FIG. 1 and FIG. 2 are sectional views showing a configuration of a tachograph reader according to an embodiment of the present invention together with a tachograph recording sheet P to be read, and 11 is a tachograph recording sheet P to be read. A disk-shaped holding table made of a transparent material for holding the sheet in an upside-down state, 12 is a disk-shaped weight body placed on the holding table 11 with the tachograph recording sheet P interposed, and 13 is a weight body 12. Is a mechanism for carrying and removing the weight body by a manual operation for carrying and removing it from the holding table 11, 14 is a rotating shaft of a motor axially attached to the center of the holding table 11, and 15 is an optical reading device.

The weight transfer / removal mechanism 13 is also used as a shaft 13a and an arm portion 13b rotatably engaged around the shaft 13a and a dust-proof cover plate that is opened and closed above the holding table 11. The lid 13b includes a cylindrical post portion 13c protruding downward near the center of the lid plate 13b, and an opening 13d formed in the bottom surface of the post portion 13c. Weight 1
Reference numeral 2 denotes a disc-shaped main body portion 12a, and an engagement portion 12 formed in a central portion of the main body portion 12a and engaged in an opening 13d on the lid plate 13b side.
It consists of b and.

As shown in FIG. 1, when the dustproof cover plate 13b is rotated upward, the weight 12 is engaged with the cover plate 13b and removed from the holding table 12 above the tachograph. A recording sheet is removed, and a new tachograph recording sheet to be read is conveyed and placed on the holding table 12 by manual operation.

After that, as shown in FIG. 2, when the cover plate 13b is returned to the horizontal position, the weight 12 is transported onto the holding table 11 and placed on it. When the weight 12 is placed on the holding table 11, the engagement between the engaging portion 12a formed in the central portion of the main body 12a and the opening 13d on the cover plate 13b side is released.

In this disengaged state, the holder 11 is rotated at a predetermined speed as the rotary shaft 14 of the motor rotates. In the optical reading device 15, a one-dimensional line sensor is arranged along the radial direction of the holding table 11, and the recording sheet P placed on the holding table 12 in an inverted state is the one-dimensional line sensor. Cross the top at a predetermined speed. Along with this, two-dimensional image information is read by a combination of main scanning in the extending direction of the line sensor and sub-sub scanning in the rotating direction of the holding table.

3 and 4 are sectional views showing the construction of a tachograph reader according to another embodiment of the present invention, in which 21 is a disk-shaped holding base made of a transparent material and 22 is a disk-shaped weight. Reference numeral 23 is a body, 23 is a weight conveying / removing mechanism, 24 is a rotation shaft of a motor, and 25 is an optical reading device.

The weight transporting / removing mechanism 23 includes a shaft 23a, a dustproof cover plate 23b that is rotatably engaged around the shaft 23a and opened / closed above the holding table 21, and the vicinity of the center of the cover plate 23b. The nut 23c is fixed to the nut 23c, the bolt 23d is screwed to the nut 23c, and the stopper 23e.
The weight 22 is a metal disc 22 having a center hole.
It is composed of a, a disc 22b made of sponge in which a center hole is also formed, and a cylindrical body 22d with a flange fitted in the center hole. An opening 24b is formed at the tip of the main body 24a of the rotary shaft 24 of the motor.

As shown in FIG. 3, when the dustproof cover plate 23b is rotated upward, the weight body 22 is engaged with the cover plate 23b and removed from the holding table 22 above it, and the read tachograph is read. The recording sheet is removed, and the new tachograph recording sheet to be read is conveyed and placed on the holding table 22 by manual operation.

Then, as shown in FIG. 4, the cover plate 23b is attached to the stopper 23e.
When it is returned to the horizontal position by, the weight body 22 is transported to and placed on the holding table 21. In the mounting state of the weight body 22 on the holding table 21, the engagement between the weight body 22 and the transport / removal mechanism 23 thereof is released as the engagement between the bolt 23d and the flanged cylindrical body 22d is released. .

In this disengaged state, the holding table 21 is rotated at a predetermined speed in accordance with the rotation of the rotary shaft 24 of the motor, and the two-dimensional image information drawn on the tachograph recording sheet is read.

(Effect of the Invention) As described in detail above, according to the present invention, the engaging portion that automatically releases the engagement with the weight only when the weight is placed on the holding table is provided. This is because the structure is provided with a mechanism for conveying and removing the weight body that it has. The effect that the recording sheet can be efficiently conveyed and removed by the manual operation is obtained.

According to one embodiment of the present invention, the weight transfer / removal mechanism doubles as a dust-proof lid that is opened and closed above the holding table, so that the weight can be transferred and removed more efficiently. The effect that it becomes possible is played.
