48 is a first loading sensor, and 49 is a second loading sensor, which are provided on the flat part 70 of the loading block 12 and detect insertion of the microfiche F. Generally, when a microfiche F is inserted into a retrieval device such as a reader printer, it is not necessarily inserted at right angles to the insertion lower (see Figure 1), and is often inserted diagonally, especially if the operator is inexperienced. It may be inserted from. Therefore, in this embodiment, a pair of loading sensors 48, 49 are provided on the left and right sides, and the loading sensors 48, 49 are linked with the drive motor 33, so that the tip of the microfiche F is connected to the supporting tool 22 of the holding part 22.

It is arranged ahead of the upper loading sensor 48 in the film insertion direction. This sensor 7E has a large number of photodiodes arranged in a direction perpendicular to the insertion direction of the fish film F, that is, along the width direction of the barcode 92, and instantly reads the barcode 92 when the fish film F is inserted. read

Next, the principle of operation of the microfiche moving mechanism 3 will be explained with reference to FIG. 2.

First, the controller unit 5 is operated to move the XY carrier main body 17 to the home position (a position where microfiche can be inserted), and the tip of the lifting lever 37 is engaged with the upper glass 23.

Whether or not the XY carrier main body 17 is at the home position is detected by a home position sensor (not shown). Next, the solenoid 40 is turned on and the lifting lever 37 is operated to lift the upper glass 23 upward. When the microfiche F is inserted from the insertion lower (see Figure 1), the first loading sensor 48 detects it, then the second loading sensor 49 detects it, and at the same time, the drive motor 33 rotates in the direction of arrow G. A microfiche F is inserted between the upper glass 23 and the lower glass 24. At the same time, the barcode 92 of the microfiche F passes above the M-pick sensor 71, so the barcode information is read by the reading sensor 51. The read information is automatically set in the control circuit of the fish moving mechanism, which will be explained later.

As the microfiche F passes through the two loading sensors 49, the solenoid 40 is turned off and the lifting lever 37 is lowered, and the upper glass 23 is lowered accordingly. A fish F is held between an upper glass 23 and a lower glass 24. Next, after a certain period of time has elapsed, the second linear pulse smoke 16 is driven to move the X-Y carrier main body 17.
is moved in the direction of arrow Y to separate the XY carrier main body 17 from the loading block 12, and then the drive motor 33 is stopped. Then the controller section 5
Desired information retrieval can be performed by appropriately operating the .

Further, when removing the microfish F from the microfish moving mechanism 3, the controller section 5
to move the X-Y gear rear body 17 to the home position. When the 31 XY carrier main body 17 is set at the home position, the solenoid 40 is turned on and the lifting lever 37 is operated to lift the upper glass 23, and then the drive motor 33 is driven to remove the microfiche. F is removed from the microfiche moving mechanism 3. Micro Finsch F
Confirmation of detachment can be easily detected by the first loading sensor 48 and the second loading sensor 49. Finally, after a predetermined period of time has elapsed, the drive motor 33 stops, and the series of operations ends.

FIG. 7 shows an example of the controller section 5. As shown in FIG. In the figure, 50 is a Y-axis address key for specifying the Y-axis address of the microfiche F, and 51 is an X-axis address key for specifying the X-axis address. Further, 52 is an eject key, which connects the first linear pulse smoke 14 and the second

Further, 60 is an indicator light such as a light emitting diode that indicates that the XY carrier main body 17 is at the home position, and indicates whether or not the microfiche F can be inserted.

Reference numeral 61 is a display section, in which the Y-axis address key 50,
Axis address key 51. Information necessary for retrieval, such as information specified by the index key 58, mode selection key 59, etc., barcode information read by the reading sensor 51, ie, format information, etc., is displayed.

FIG. 10 shows a system configuration for controlling the reader printer. The system is the control system 10 of the reader printer main body 2.
1 and the control system 102 of the microfiche moving mechanism 3
It has two features. The recontrol systems 101 and 102 are interconnected through an interface 103. The interface 103 transmits a predetermined control signal from one control system to the other control system when searching in reader mode, searching in print mode, printing, and the like. For example, in the case of so-called multi-printing in which multiple pages imprinted on microfiche are printed, a signal instructing the multi-print mode from the control system 102 of the microfiche moving mechanism 3 to the control system 101 of the reader printer main body 2 and a print signal and conversely, the latter control system 101
A print busy signal is transmitted from the control system 102 to the control system 102 of the former.

The print busy signal is a signal that prohibits movement of the microfiche moving mechanism so that it does not unexpectedly move in response to other signal input during printing.

Both of the two control types 101 and 102 have microcomputers 104 and 105, ROMs 106 and 107, and RAM 1.
08, 109, and the reader printer main body side control system 101 has input keys such as various timing sensors 110, print switches, sheet number input key 1N-P/P-P switching key, etc. on the input board of the microcomputer 104. 111 is connected to the output port, and a drive equipment group 112 such as a main motor, a developing motor, and a solenoid, a controlled equipment 113 such as a charger, a static elimination charger, and a developing bias, and a display device 114 such as a sheet count display and various LEDs are connected to the output port. .

On the other hand, the control system 102 of three examples of microfiche moving mechanisms
Loading sensors 48, 49, and X are connected to the input ports of the microcomputer 105.

A sensor group 115 such as a Y-axis home position sensor and a barcode reading sensor 71 is connected to an input key group 116 such as a numeric keypad, Y-axis key, memory key, mode key, print key, and start key, and an axis, Y
Drive equipment group 117 such as shaft step motor and loading motor, fine adjustment/feed LED, and home position LED
It is connected to a display group 118 such as. Unlike other sensor groups, the barcode reading sensor 71 is connected to the microcomputer 1 via an N/P switching circuit 72 and a processing circuit 73.
It is connected to the input port of 05. N/P switching circuit 7
2, since the black and white of the barcode is inverted depending on whether the applied microfiche F is a negative film or a positive film, the sensor signal level is inverted depending on the type of the applied microfiche F. The processing circuit 73 is a circuit that shapes the waveform of the barcode reading signal and binarizes it into a white bar signal and a black bar signal, and its specific configuration is disclosed in, for example, Japanese Patent Application No. 1983-7633 proposed by the present applicant. It uses a built-in circuit.

FIG. 11 is a flowchart illustrating the operation of the control system 102 when searching for the microfiche F containing the barcode 92. Assume that no film is loaded in the X-Y carrier section. At this time, nothing is displayed on the display of the operation panel. Next, when loading on the film is started in step 1, the process proceeds to step 2, where the barcode written on the film is read by the reading sensor 71. The read information is stored in RAM1 of the control system 102 in step 3.
09 and displayed on the operation panel display in step 4. For example, if a microfiche with a 270F film format, rows (B to P) and columns (1 to 18) are specified, and two indexes is loaded, that information is sent to the control system 102. It is automatically set and displayed on the display section 61 as shown in FIG. Therefore, the operator does not have to input the above information manually, which is very convenient.

In this way, once the loading of the film is completed (step 5), the reader printer determines where the index position is based on the barcode information read earlier, automatically performs a search, and projects it on the screen (step 6).
). After that, perform the same operation as a normal search (step 7), and after completing the search, confirm that the eject key has been pressed in step 8, and then clear the read barcode information (step 9). As a result, the display on the display section 61 becomes blank (step 10). When performing a search, in the case of a so-called multi-film search, which is performed over a plurality of consecutive pages, the loaded film can be confirmed by displaying the serial number of the loaded film on the display section 61. be able to.

In the above embodiment, the information necessary for the search is recorded in the fish in the form of a bar code, but it goes without saying that the information may be recorded in a code other than a bar code. In that case, you can simply replace the reading sensor with a compatible one.

As described above, according to the microfiche retrieval device of the present invention, information necessary for retrieval is encoded and recorded on the microfiche side, read at the time of loading, etc., and automatically transmitted to the control system. Since the settings are set to , the necessary information can be entered without bothering the operator, which is especially convenient for general users who do not have much knowledge about microfiche.

Furthermore, the possibility of errors in information settings can be eliminated, and a highly reliable search can be realized.
