An embodiment of the present invention will be described below with reference to the drawings. First, the present invention is described with reference to FIGS.
An embodiment applied to the library system described above will be described. FIG. 1 is a block diagram showing the overall configuration of an embodiment of the present invention. FIG. 1 shows only the parts necessary for the embodiment of the present invention, and other parts are not shown.

In this embodiment, the moving means for moving the removable recording medium between the first transfer position in the first direction and the second transfer position in the second direction is the same as that shown in FIG. , And the junction port section 18 described with reference to FIG.

That is, the first moving means of the device of the present invention is either the upper junction port or the lower junction port of the junction port section 18, and the second moving means is the upper junction port or the lower junction port. Either is the other.

The first device group corresponds to the console row L1 described in FIG. 5, and the second device group corresponds to the console row L2.
It corresponds to L3. Further, the first recording medium transport section corresponds to the cassette transporter 16a described in FIG. 5, and the second recording medium transport section corresponds to the cassette transporters 16b and 16C.

In the present embodiment, in the junction console 1J, the movement in which the movement start time of the other junction port is shifted with respect to one of the upper junction port or the lower junction port of the junction port section 18. Control means 170 is provided.

The movement control means 170 is a delay section to which a movement control command to the junction port section 18 is input. The movement control command input during non-activation is output as it is, and is input during activation. A delay unit 171 that outputs a movement control command after a predetermined delay setting time has elapsed; and a delay time setting unit that sets and starts the delay setting time in the delay unit 171 according to the movement control command output from the delay unit 171. 172.

The delay unit 171 and the delay time setting unit 172 are provided, for example, on the junction control board 80a of FIG.

The delay section 171 is composed of, for example, a wait timer (WAIT timer), and always counts down by interrupt processing.

Next, the operation until the junction carrier of the junction port section 18 starts moving will be described with reference to the flowchart of FIG. 2 and the time chart of FIG. First, when a command to move, for example, an upper junction port is issued from the upper control board 60a (step S1), it is checked in step S2 whether the wait timer constituting the delay unit 171 has been activated.

If the wait timer is running, it counts down and waits until it becomes zero. Then, when the value of the wait timer is zero or becomes zero, the delay time setting unit 172 sets a predetermined delay setting time T in the wait timer (the delay unit 171) in step S3, and then returns to FIG. At time _t1a in (b), the transfer operation of (the transfer body 111a of) the upper junction port is started (step S4).

Here, at a time when the delay set time T does not elapse from the time t _1a , a new host control board 60 is newly added.
Assuming that a move command for the lower junction port is issued from a, the move command is waited in step S2 until the wait timer becomes zero (until the delay set time T elapses), and then, as shown in FIG. The transfer operation is started at time t _1b in FIG.

It goes without saying that a transfer command input after the elapse of the delay set time T starts the transport operation without delay at the time of receiving the command.

As described above, even when movement commands of the upper and lower junction ports are issued almost simultaneously, the operation start time can be shifted by the delay set time T of the wait timer, and the upper and lower junction ports operate simultaneously. Getting started can be avoided.

Therefore, the peak current of the motor at the start of the operation does not overlap, and the end time of the operation is not the same as t _2a and t _{2b in} FIG. 3 (b). Does not increase, the capacity of the power supply can be reduced, and the cost can be suppressed.

The delay setting time T of the wait timer
Is set, for example, in a transition period until the motor current falls from the peak current to the rated current. With this setting, it is possible to reliably prevent the two peak currents from overlapping.

Next, an embodiment in which the control method of the present invention is applied to the library system shown in FIGS. 4 to 13 will be described. In the present embodiment, the function of the movement control means 170 described in FIG. 1 is executed, and the movement control of one of the upper junction port and the lower junction port is performed with respect to the other junction port. This is to perform movement control for shifting the start time.

The movement control is performed, for example, as shown in the flowchart of FIG. 2, by starting a movement control command for one of the upper and lower junction ports for a predetermined time (eg, The delay setting time T) described in FIG. 3 is control for prohibiting execution of a movement control command for the other junction port.

The predetermined set time is, for example, from when power is supplied to the DC motors 110a and 110b for driving the respective junction carriers of the upper or lower junction port until the motor current reaches the rated current. Set a period.

According to the present embodiment, for example, during the predetermined set time after the execution of the movement control command for the upper junction port is started, the execution is prohibited even if the movement control command for the lower junction port is issued. Is done.

Therefore, the execution of the movement control command for the upper junction port and the movement control command for the lower junction port are not started at the same time, and are not ended at the same time. As a result, the D driving each junction carrier of the upper or lower junction port is
The peak currents of the C motors 110a and 110b do not overlap, the instantaneous current consumption does not increase, and the power supply capacity (ie, cost) can be reduced.

Further, according to the present invention, the control method described above, that is, a recording medium moving means having first and second moving means for moving a detachable recording medium between a plurality of different transfer positions. A control method for shifting a movement control start time of the other moving means with respect to one of the first moving means and the second moving means, the computer comprising: Is recorded on a computer-readable medium.

The computer recorded in the junction console 1J of the cassette library 1 configured as shown in FIG. 1, for example, reads and executes the program recorded on the medium configured as described above, thereby, for example, issuing a movement control command to the upper junction port. During a predetermined set time after the execution is started, the execution is prohibited even if a movement control command for the lower junction port is issued.

Therefore, the movement control command for the upper junction port and the movement control command for the lower junction port are not simultaneously started or ended simultaneously. As a result, the D driving each junction carrier of the upper or lower junction port is
The peak currents of the C motors 110a and 110b do not overlap, the instantaneous current consumption does not increase, and the power supply capacity (ie, cost) can be reduced.

In the above embodiment, the present invention is shown in FIGS.
Although the present invention is applied to the library system shown in FIG. 3, the present invention is not limited to this, and the present invention is configured to have first and second moving means for moving a removable recording medium between a plurality of different transfer positions. The same operation and effect as described above can be obtained even when applied to another device and its control method.
