  When the moving vehicle under measurement 24 reaches the vehicle presence / absence detection device 30, as shown in FIG. 11, the vehicle presence / absence detection device 30 detects the measurement vehicle 24 (ON) and performs the detection. The vehicle length calculation unit 31 is notified as presence information. When the vehicle length calculation unit 31 obtains this information, the distance measuring device 28 causes the distance measuring device 28 to measure the distance between the headlight tester 1 and the measured vehicle 24 and passes the distance through the vehicle. Store as starting distance.

  Then, as shown in FIG. 12, when the vehicle under measurement 24 moving forward toward the headlight tester passes beyond the vehicle presence / absence detection device, the vehicle presence / absence detection device 30 moves the vehicle under measurement 24. When no longer detected (OFF), the vehicle length calculation unit 31 is notified of the no-information no longer detected. When the vehicle length calculation unit 31 obtains this non-information, the distance measurement device causes the distance measurement device to measure the distance between the headlight tester 1 and the vehicle under measurement 24 and finishes passing the distance through the vehicle. Remember as time distance.

  The vehicle length calculation unit 31 stores a value obtained by subtracting the vehicle passage end time distance from the vehicle passage start time distance as a vehicle length. If necessary, the display control unit 9d causes the monitor 7 to Display it.

(2.2. Measurement of vehicle height)

The headlight tester 1 is moved in the left-right direction manually or automatically until it coincides with the vertical line 27. For example, the measurer moves the position of the headlight tester 1 relative to the rail 3 to the operation unit 16. It is set as the starting point (for example, 0 position) of the left-right direction moving amount measuring device (note that it may be automatically performed by image processing or the like).

  Next, as shown in FIG. 8B, until the other end side portion (for example, the right side) of the measured vehicle 24 displayed on the monitor 7 coincides with the vertical line displayed on the monitor 7. The headlight tester 1 is moved in the left-right direction manually or automatically. For example, the measurer uses the operation unit 16 to set the position of the headlight tester 1 relative to the rail 3 as the end point of the left-right direction movement amount measuring apparatus. (It may be automatically performed by image processing or the like), whereby the lateral movement amount measuring device 25 stores the movement amount from the start point to the end point as a vehicle width, and if necessary, the The display control unit 9d displays on the monitor 7.

  When the vehicle to be measured and the headlight tester are greatly inclined to measure the vehicle width, that is, as shown in FIG. 9 (a), the center line of the vehicle to be measured and the head When the angle formed with the front surface of the light tester (headlight light receiving unit) is not a right angle, the headlight tester 1 is tilted manually or automatically by the tilt mechanism unit so as to be a right angle.

  Specifically, for example, the vertical line 27 displayed at the center of the monitor 7 includes two different points (for example, the center in the left-right direction of the room mirror mounting portion and the center in the left-right direction of the emblem) in the front-rear direction of the vehicle. The headlight tester 1 is tilted and moved in the left-right direction so that the position coincides with

  Then, after the angle formed by the center line of the vehicle and the front surface 35 of the headlight tester 1 becomes a right angle and correctly faces, the headlight tester 1 is moved along the rail by the method described above, and the movement Measure the amount.

  The vehicle width calculation unit 26 calculates the vehicle width from the tilt amount obtained by the tilt amount measuring device and the movement amount from the desired calculation formula, stores the vehicle width, and is necessary. In response, the display control unit 9d displays on the monitor 7.

(2.4. Installation of target plate)

  Next, the operation unit 16 such as a selection screen displayed on the monitor 7 of the vehicle dimension measuring device is operated to select target plate installation.

  Then, the distance measuring device 28 measures the distance between the measured vehicle 24 and the target plate fixed later, and displays it on the monitor 7.

  Then, the measurer brings the measured vehicle 24 into and out of contact with the headlight tester so that the distance between the measured vehicle 24 and the target plate becomes a desired distance.

  Next, in the case of measurement by various sensors, since it is necessary to correctly face the vehicle under measurement and the headlight tester, the center line 34 of the vehicle under measurement 24 and the headlight of the headlight tester 1 are measured. As shown in FIG. 9A, the headlight tester 1 is tilted manually or automatically by the tilt mechanism so that the angle formed with the front surface 35 of the tester is a right angle. Move left and right.

  Specifically, as described in the vehicle width measurement, for example, two different points in the front-rear direction of the vehicle are positioned so as to coincide with the vertical line displayed at the center of the monitor 7. The headlight tester 1 is tilted.

  If necessary, the distance measuring device 28 measures the distance between the measured vehicle 24 and the target plate 32. If the distance is not a desired distance, the measured vehicle 24 is separated from and attached to the target. Let

  And after making it correctly face, the said target board 32 is correctly positioned and attached to the center of the light-receiving surface of the headlight light-receiving part 6. FIG.
