Data transmission and reception etc. are performed under the control of 2.

In this example, the MPU is M6800 manufactured by Motorola,
The company's M6821 is used as the interface IPIA.

Below, the operation when the deck part of the loading device of this embodiment is lowered to the specified position is shown in Figure 4. This will be explained with reference to the control flowchart of +1 style a poem.

In step 301, it is determined whether one of the decks is in the specified position during loading and a signal from the micro switch 109 in Figure i3 is generated.If neither deck is in the specified position, the wooden step 301 is used to If the deck is in the specified position, proceed to step 302, and
Determine which deck is in the specified position. If the deck is A, steps 303 and subsequent steps are executed, and if the deck is B, the B block portion surrounded by the chain line is executed. This B block portion performs the same processing as the A block portion surrounded by the chain line after step 303, and the A deck and B deck are simply exchanged, so a description of the processing of the B block will be omitted.

Therefore, the control when the deck is loaded with the specified amount will be explained from step 303 onward for the case where the deck A is at the specified position.

In step 303, it is checked whether or not the simultaneous loading mode is on both decks A and B. If it is not the simultaneous loading mode, step 30
Step 4 proceeds to step 309, where it is checked whether loading is possible on the other deck y and the superior deck B. If loading is possible, proceed to step 309 and stop loading onto deck A.

Subsequently, in step 310, an instruction is given to load onto the B deck, and from then on, loading onto the B deck is performed.

If it is determined in step 304 that loading onto deck B is not yet possible, the process proceeds to step 3051.

The lamp 115b of the B deck is blinked to notify the operator.

Next, in step 306, it is checked whether or not deck A has loaded the maximum number of sheets, and if the maximum number of sheets has been loaded, step 3 described below
If the paper is not loaded, the process goes to step 307, where the operator takes out the loaded paper from the paper container 12 of the B deck and checks whether or not the paper container 12 has been set on the stacking plate 171-. If so, check whether the size of the paper container 12 set corresponds to the position of the alignment guide 16 specified by the lever 32,
If not, the process returns to step 305 and the operator is alerted.

If the load is +5, the process proceeds to step 308, where the lamp 115 of the B deck is turned off, and the B deck is raised to the loading position. and then step 30
The process advances to step 9 to execute the above-mentioned processing.

Here, we have explained the case where B deck is not a#: possible, but fI! Decks that are not in use shall be able to independently take out stacked sheets and set them in the loading position, regardless of the loading operation.

In step 303, in the case of simultaneous loading mode, the loading cannot be changed to deck B, so the process proceeds to step 311, where loading on deck A is stopped, the 1 indicator lamp 115 is blinked, and the loading device is stopped as necessary. . After that, proceed to step 312 and set the container as in step 306. In step 313, as in step 307, check whether the container size and the alignment guide position correspond.
If not, the process returns to step 311, and in step 314, the A deck is raised to the loading position in the same way as in step 308, and in step 315, loading on the A deck is resumed, and the process ends.

It was explained that loading on the loading deck at the specified position during the control should be stopped immediately, but it does not shift immediately and other decks can be loaded while the maximum loading number is reached, and even if that deck becomes able to load, the current loading If the stacked deck has not reached the maximum number of stacked sheets, control may be performed so that the stacks are not transferred to another deck.

Also, a microswitch that detects the specified position of the deck,
Even if it is used in combination with a counter device that detects the specified number of sheets, the gist of the present invention does not change.

Effects As explained above, according to the present invention, before the loading section of the loading device becomes unloadable, another loading section is enabled for loading, and the loading section that becomes unloadable is automatically loaded. Loading can now be changed to the loading section, and the entire system, including the loading device, does not have to stop.

Furthermore, by alerting the operator when it is necessary to enable loading in the loading section, it has become possible to load a large amount continuously without stopping loading.
