After the stepping motor 51 is driven, for example, in the forward direction by a predetermined number of drive steps for positioning the elevating frame 54 (step S3), the process proceeds to step S5.

If the up / down frame detection signal is input (Y in step S1), step S3 is skipped and the process jumps to step S5.

In step S5, it is detected whether or not the tray unit accommodation signal from the switch 27 has been input.
If the tray section accommodation signal has not been input (N in step S5), step S5 is repeated until the signal is input (Y in step S5). It is detected whether or not an input has been made (step S7).

If the lock signal is not input (N in step S7), step S7 is repeated until the lock signal is input, and if the lock signal is input (Y in step S7), the encoder pulse from the encoder 64 is output.

It is detected whether or not the idling resumption signal is input from the idling resumption detection means 82, that is, whether or not the engine has been restarted (step S46). When the idling restart signal is not input (step S
In step N46), step S46 is repeated until an input is made, and if an input is made (Y in step S46),
An encoder pulse from the encoder 64 is captured (step S47).

If the encoder pulse is not "00000", that is, if the traveling speed is not zero (N in step S48), the process proceeds to step S27, and if the encoder pulse is "00000", that is, the traveling speed is zero. If there is (Y in step 48), the process proceeds to step S49.

Next, the stepping motor 63 is driven to rotate in the reverse direction with the same number of driving steps as in step S44 (step S44).
49) The process proceeds to step S27 described above, where the travel distance and the travel speed are calculated based on the travel pulse, and
