Furthermore, 29 is a micro switch, and the storage frame 1

The amount of rotation is generated as an up/down signal and a clock signal.

34 is a count conversion circuit, which specifically forms an up/down count, counts based on the clock signal, counts ten when the up/down signal is up, and counts one when the up/down signal goes down. Furthermore, the up/down count is the up/down signal;

It is configured to read the 0N10FF state of the optical sensor 30, output a medium remaining amount display signal, etc., which will be described later, to the teller operation unit 36, and further read the 0N10FF state of the near full, near end setting keys, etc. of the medium on the storage. There is.

FIG. 5 is an external view of the teller operation section 36.

Numeral 38 is a near-full setting key for setting the near-full detection amount of the storage, 39 is a near-end setting key 40 for setting the near-end detection amount of the storage, and input key 41 is for inputting each of the above-mentioned detection amounts. A clear key 42 is a liquid crystal panel display for displaying the set value of each detected amount, and 43 to 52 are indicator lamps that display the medium storage capacity of each storage. For example, in this embodiment, the amount of media stored in each storage is set to 100% when each storage is full, and can be displayed in 10% increments.

FIG. 6 is a flowchart showing the storage capacity checking operation of the medium storage capacity detection device of this embodiment, and the procedure for checking the storage capacity will be explained below using this flowchart and referring to FIGS. 1 to 5. .

When checking the storage capacity of the media starts, the Sl
First, the present medium capacity detection device determines whether an initial operation should be performed. This is because if the initialization has not been performed, the count value from the count conversion circuit section 34 (hereinafter referred to as count value) is undefined, and the position of the stage 2 is unknown.

S2 If it is determined that initials are required in S1 above,
Bring down stage 2.

S3 While performing S2, the control circuit section 35 reads whether the microswitch 29 is turned on or not, and continues downing the stage 2 until the microswitch 29 is turned on.

When the microswitch 29 is turned on, the count value is initialized as described above (in this embodiment, it is assumed to be 0).

S4 At this time, it is determined whether the optical sensor 30 is not ON, and if it is ON, the process advances to S12, and if it is OFF, the process advances to S5.

S5 When stage 2 is increased from the point where the count value becomes 0 in S4, the count value is also increased in accordance with the increased amount.

S6: Read the count value while stage 2 is up. Let this read count value be N.

S7 Set the count value when stage 2 reaches the maximum limit with no medium in the storage as M as a fixed value,
The count value N read in S6 above is this count value M
Determine if it is smaller than.

88 Count value N <When the count value M is reached, that is, when at least a certain amount of media is accumulated on the stage 2, the optical sensor 30 determines whether it is ONL or not, and the O
If you have not done N, you can still ascend stage 2, so S
Return to 5. Further, when the optical sensor 30 is turned on, the count-up operation of the count conversion circuit section 34 is stopped as described above.

S9: Since the optical sensor 30 has been turned on, the stage 2 is stopped moving up.

310 Read the count value. As described above, the count value N stops counting from the moment the optical sensor 30 is turned on, and the count value N is held.

In turning on the Sll indicators 43 to 52,
Capacity P = (M - N) with count value N and count value M
/M x 100χ is executed. For example, N=1
60, M=250, capacity P=(250-160
)/250X 100 = 36 (%), so
If the display is rounded up, it will be 40%, indicating indicator 4.
3 to 48 are clarified, and indicators 49 to 52 are lit. Furthermore, regarding the near-full set value Q and near-end set value R, which will be described later, if P≧Q, a message such as "The medium is full" is displayed on the liquid crystal panel display 42, and if P≦R, Similarly, [media is becoming scarce. ” etc. will be displayed.

S12 If the optical sensor 30 is ON in S4,
Since stage 2 cannot be raised, the stage up operation is immediately stopped.

313 Since the micro switch 29 is ON and the optical sensor 30 is ON, it is determined that the storage capacity is full, and the liquid crystal panel display 4 is turned on.
2, "The medium is full. Display a message such as j.

S14 Following S13, all indicator lamps 43 to 52 of the storage are turned on.

315 When the count value N≧count value M at 37, that is, when there is almost no medium or no medium on the stage 2, it is determined whether the optical sensor 30 is not ON, and the O
If N, there is at least one medium on the stage 2, so the count value N=M-1 (this prevents the calculated value from becoming 0 or - when calculating the indicator display.

), proceed to S9, and if it is not ON, there is no medium on stage 2, so the count value N = 0.
As a result, the process proceeds to S16.

S16 Stop the stage 2 up operation.

517 At 515, it is determined that the medium capacity of the storage is empty, and a message such as "There is no medium left" is displayed on the liquid crystal panel display 42.

318 Following S17, all the indicator lamps 43 to 52 of the storage are turned off.

319 If it is determined in step 31 that it is not necessary to execute the initial operation, the count value is guaranteed regardless of the operation of stage 2 or the presence or absence of media in and out of the storage, so first make sure that the optical sensor 30 is turned on. Determine if it is present and turn it on.
L, if not, proceed to S5.

Since it was determined in S20 319 that the optical sensor 30 is ON, it is determined whether the microswitch 29 is not ON, and if ONL, the microswitch 29 is ON and the optical sensor 30 is ON, which are the same conditions. Proceed to 312.

Since the microswitch 29 was turned off in S21 320, the stage 2 is brought down and steps 519 to 521 are repeated.

When the above operation flow ends in 311, S18, or 314, the storage capacity check ends.

FIG. 7 is an operation flowchart for setting the near-full or near-end detection amount, and the setting procedure will be explained with reference to FIG.

For example, in the case of near-full setting, the operator presses the SAI near-full setting key 38 while the device is idle.

SA2 SAI causes the previous near full setting value Q to be displayed on the liquid crystal panel display 42.

SA3 Next, if the clear key 41 is pressed, the near full setting value Q=O is set and the process goes to SA4; if it is not pressed, the process goes to SAT.

SA4 Press the numeric keypad 40 from 0 to 9 to enter a new near full setting value manually.

SA5 The new near full set value is displayed on the liquid crystal panel display 42 every time the numeric keypad 40 is pressed.

SA6 If the near full setting key 38 is pressed, the near full setting is finished here; if it is not pressed, the process returns to SA4.

For example, if the 8 key of the numeric keypad 40 is pressed in SA4 → SA5 → SA6 → the 5 key of the numeric keypad 40 is pressed in SA4 → the near full setting key 38 is pressed in SA5 → SA6, the near full setting value Q = 85 ( %) and finish the near full setting.

When the SAT near full setting key 38 is pressed, the near full setting is completed, and when the SAT near full setting key 38 is not pressed, the process returns to SA3.

Note that the near-end setting flow can be executed using the same operating procedure by replacing near-full with near-end in the flowchart of FIG.

In addition, according to the present embodiment, the operation section for displaying the capacity of the medium and setting near full and near end is the teller operation section, but the operation section does not need to be included in this apparatus, for example, the host It goes without saying that the information may be displayed or set via the operating unit and interface of the computer.
