  The speed I / F 32 is electrically connected to a vehicle speed sensor (not shown), and outputs a speed signal corresponding to the speed of the vehicle to the CPU 21. The engine I / F 33 is electrically connected to an engine sensor (not shown) of the vehicle, and outputs an engine signal corresponding to the engine speed to the CPU 21. The power source V is electrically connected to the vehicle battery and supplies power necessary for the operation of the vehicle operation information collection device 1.

  Next, an example of a processing outline according to the present invention executed by the CPU 21 of the vehicle operation information collection device 1 will be described below with reference to the flowchart of FIG.

  In step S1 shown in FIG. 7, it is determined whether or not the IGN switch of the vehicle is turned on. When it is determined that the IGN switch is not turned on (N in S1), this determination process is repeated to wait for the IGN switch to be turned on. On the other hand, when it is determined that the IGN switch is turned on (Y in S1), the process proceeds to step S2.

  In step S2, a speed data collection process for collecting a speed signal from the speed I / F 32 as speed data is started, and then the process proceeds to step S3. By this speed data collection process, operation data such as speed data and engine rotation data collected during operation after delivery is collected.

  In step S3, it is determined whether or not the card C is inserted in the card I / F 30. If it is determined that it is not inserted (N in S3), the determination process is repeated to wait for insertion of the card C. On the other hand, if it is determined that it is inserted (Y in S3), the process proceeds to step S4.

  In step S4, it is determined whether or not the cover 14 is in the closed state based on the closed state detection switch 33a. When it is determined that it is not in the closed state (N in S4), this determination process is repeated to wait for the transition to the closed state. On the other hand, when it determines with it being a closed state (it is Y at S4), it progresses to step S5.

  In step S5, a card determination process is executed, and then the process proceeds to step S6. This card determination process is to cause the CPU 21 to function as the write determination means in the claims shown in FIG. 1, and determines whether writing / reading with respect to the card C inserted from the insertion slot 11 is possible. The determination result (normal / abnormal) is stored in the SRAM 23.

  In step S6, it is determined whether or not the card C is normal. When it is determined that the card C is normal (Y in S6), the warning means 15 is turned off in step S7, and in step S8, operation data corresponding to the change in operation state during operation is stored in the SRAM 23 as operation information. When the process during collection which is collected and stored is executed and the end switch 12a of the operation unit 12 is operated, the process during delivery is terminated and the process proceeds to step S9.

  In step S9, by executing the warehousing process, the card I / F 30 is requested to write the operation information stored in the SRAM 23 to the card C, and the operation information is written to the card C by the card I / F 30. The process ends in response to the end of the writing.

  If it is determined in step S6 that the card C is not normal (N in S6), that is, if the card C is abnormal, in step S10, the card abnormality alarm process is executed, so that the buzzer 16 is activated. The sound is sounded for a predetermined time, and the warning means 15 is turned on in step S11, and the process proceeds to step S12.

  In step S12 (corresponding to the transition means), the cover open process is executed, so that the solenoid 31 is turned on and the solenoid 31 is retracted, thereby being locked at a position (ON state) where it is not locked with the locking portion 14a. When the protrusion 32 is moved and the engagement between the engagement portion 14a and the engagement protrusion 32 is released, the cover 14 is moved in the urging direction by the urging force of the urging member 5 to change from the closed state to the open state. After that, the process returns to step S3, and a series of processing is repeated.

  As is clear from the above description, in this embodiment, the CPU 21 functions as the write determination means and the transition means in the claims shown in FIG.

  Next, an example of the operation (action) according to the present invention in the vehicle operation information collecting apparatus 1 having the above-described configuration will be described below.

  In starting the operation, when the operator inserts the card C from the insertion port 11 of the vehicle operation information collection device 1, the cover 14 is changed from the open state to the closed state. And the vehicle operation information collection device 1 is activated in response to turning on the IGN switch of the vehicle, starts operation data collection, and the card C is inserted into the insertion slot 11 when the cover 14 is in the closed state. It is determined whether or not the writing / reading of information to / from the card C is normal. If it is determined that the card C is normal, normal processing during shipping is performed, and the collected operation information is transferred to the card C according to the end of the operation. Write. Then, the worker changes the cover 14 to the open state, takes out the card C, and takes it back to the company or the like.

  Further, when the vehicle operation information collecting device 1 determines that the card C is abnormal, the vehicle operation information collecting device 1 warns the abnormality of the card C by ringing the buzzer 16 for a predetermined time, and closes the cover 14 after turning on the warning means 15. Transition from state to open state. Thereby, the worker can recognize that the card C is abnormal because the buzzer sound (alarm sound) is sounded and the cover 14 is open by the lighting of the warning means 15. it can. The buzzer sound stops after a predetermined time has elapsed, but since the lighting of the warning means 15 and the closed state of the cover 14 are maintained, the operator cannot hear the buzzer sound due to noise inside and outside the vehicle. However, since the possibility of recognizing the lighting of the warning means 15 and the closed state of the cover 14 is improved, it becomes easy to notice the abnormality of the card C. Therefore, since the operator confirms / exchanges the card C determined to be abnormal, the abnormal card C is not used as it is.

  According to the vehicle operation information collection device (on-vehicle device) 1 described above, the cover 14 is closed when it is determined that information cannot be written to the card (information storage medium) C inserted from the insertion slot 11. Since the vehicle operation information collection device 1 is mounted on the vehicle so that the cover 14 of the vehicle operation information collection device 1 is visible to the user, the card C is inserted into the slot. Since the abnormality of the card C can be visually recognized based on the change in the state of the cover 14 after being inserted into the card 11, the replacement of the card C with the writing abnormality can be prompted as it is. Therefore, since the user can promptly recognize the abnormality of the card C without adding a dedicated warning function for warning the writing abnormality, the loss of information stored in the card C can be suppressed. . Further, since it is not affected by noise inside and outside the vehicle, it is possible to make the user recognize the abnormality of the card C with higher probability.

  Moreover, according to the vehicle operation information collection device 1, the cover 14 is covered when the cover 14 is in the closed state, and is exposed when the cover 14 is in the open state so as to visually warn the user of the open state. As a result, the warning means 15 makes it easier for the user to notice the open state of the cover 14, making it easier to recognize an abnormality in the card C and suppressing loss of information stored in the card C.

  In the above-described embodiment, the case where the cover 14 is slid in the width direction of the main body 2 has been described. However, for example, a configuration in which an arbitrary end portion of the cover 14 is opened and closed with the rotation center as a rotation center can be used. .

  In the above-described embodiment, the case where the warning means 15 in the claims is realized by the LED has been described. However, the present invention is not limited to this, and the open state of the cover 14 can be easily recognized by the driver. If it is a structure, it can be set as various different embodiments. For example, in the embodiment a shown in FIG. 8A, a paint having a warning color, a bright color, or the like different from the material color (for example, black) of the front case 3 of the main body 2 of the vehicle operation information collecting apparatus 1 is used. The case where it apply | coats to the surface of the recessed part 3a of case 3 and is set as the warning means 15a is shown. Further, in the embodiment b shown in FIG. 8B, a warning member 15b is formed by sticking a white, yellow or other seal member on the surface of the front case 3 exposed when the cover 14 is opened. Shows the case.

  Even if the warning means 15a, b are configured in this way, when the cover 14 changes from the closed state to the open state after the card C is mounted, the warning means 15a, b and the front case 3 are different in color, so that Since it is easy for a person to notice the open state of the cover 14, the abnormality of the card C can be visually recognized by the open state of the cover 14 as described above. it can.

  Furthermore, in the above-described embodiment, the case where the in-vehicle device of the present invention is the vehicle operation information collecting device 1 has been described. However, the present invention is not limited to this, for example, an on-board device of ETC, a car navigation device, etc. The in-vehicle device of the present invention can also be applied.

  As described above, the above-described embodiments are merely representative forms of the present invention, and the present invention is not limited to the embodiments. That is, various modifications can be made without departing from the scope of the present invention.
