Abstract

PURPOSE:To reduce memory capacity to be used by performing frame retrieval and printing with one instruction. CONSTITUTION:A control means 16 which executed previously registered instructions successively waits for the instruction for performing the retrieval and printing at the same time. When a STOR instruction is present during the execution of the memory, a target frame is retrieved and it is checked whether or not the retrieval ends normally. When the retrieval ends normally, the communication state of a printer 25 is confirmed and when the communication with the printer 25 is in process, a printer indication is generated to finish the operation. When the communication with the printer 25 is not in process, a display 'W' meaning a stand-by mode is made on a display unit 19 and ENTER key input is expected. During this period, a user can directly command the printer 25 to print out the retrieved frame. When the ENTER key is pressed after the printing, the operation ends and the subroutine is exited from so as to execute a next instruction.

Description

[Detailed description of the invention]

2. Description of the Related Art An automatic retrieval device having a function of retrieving image frames according to stored information input into an internal memory generally includes an automatic retrieval device 100 for retrieving image frames of a film and a retrieval image frame as shown in FIG. The automatic search device 100 is electrically or mechanically connected to the reader printer 125 so that a print output command can be output from the automatic search device 100 to the reader printer 125.

Automatic search device 100, which has an internal memory and is capable of searching and printing out films according to instructions stored in the memory, searches image frames on the film as instructions that can be registered in the memory. It has a search control command to control the output of the retrieved image frame to the printer 125, and a print control command to control the output of the retrieved image frame to the printer 125.

[0004] There is also a method in which a separate memory is used to perform an automatic search simply by inputting a registered search target address, and a setting is made so that printing is automatically performed after the search.

[0005]

[Problem to be solved by the invention] As an example, FIG. 6(a)
There is an instruction sheet for searching and printing as shown in FIG. 6B, and an example in which the instructions are registered internally in a conventional automatic search device 100 is shown in FIG. 6(b). As shown in Figure 6(b), when performing automatic execution using internal memory,
In most cases, it is a combination of (image frame search, then printout).

[0006] Therefore, there are many cases that could normally be expressed with one instruction, which results in wasted memory. Furthermore, there is a limit to the internal memory in which instructions can be registered, and increasing the memory unnecessarily can lead to increased costs.

[0007] When executing the above instructions using a completely separate memory, it is not possible to change the film in the middle, so it is necessary to re-set each time the film is changed, which is extremely time consuming. Freedom is limited.

Furthermore, in the current command system, if communication with the printer is not performed, only frame retrieval is continued without interruption, or operation is interrupted with a printer error displayed. For this reason, it is necessary to use a printer with which the search device can communicate, which is a major problem for general-purpose search devices.

The present invention has been made to solve the above problems, and its purpose is to provide an automatic microfilm retrieval device that can perform frame retrieval and printout with a single command. be.

Another object of the present invention is to enable the interpretation of print commands in a search device that does not communicate with a printer to be changed.

[0011]

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an automatic microfilm retrieval device having a control means for continuously executing pre-registered commands, in which the control means performs a retrieval operation. It is characterized by having an instruction to perform print output at the same time.

[0012] Furthermore, when communication with the printer is not performed, it is preferable that the control means change and interpret the print output command into a key input wait command.

[0013]

[Operation] In the present invention having the above structure, the control means performs frame search and printout with one command.

[0014] Furthermore, if the control means changes the print output command to a key input wait command when communication with the printer is not performed, even in an automatic search device that does not have a communication function with the printer. Advance registration to memory,
Functions such as communication control with external devices are also effectively used.

FIG. 3 shows an example in which the image shown in FIG. 6(b) in the conventional example is registered in the memory according to this embodiment. The STOR command used here searches for the frame specified by input, and after searching, automatically performs a printing operation.

Furthermore, when executing the command registered in the memory using the JOB key, the number of prints to be executed can be specified by all STOR commands in the memory by executing the command in the form (number of prints + JOB).

As a result, the amount of memory used can be reduced to about 70% compared to the conventional example shown in FIG. 6(b), and more instructions can be registered with less memory.

In addition, by using this command in a form that allows it to coexist with the film 1 rewind command, etc., it is possible to input a variety of commands.

Further, when communication is not being performed with the printer 25, the print command and STOR command among the commands registered in the memory are executed according to the flowchart shown in FIG. This flowchart will be explained below.

First, if a STOR instruction exists during memory execution, a search for a target piece (F1) is performed, and it is checked whether this has been completed normally (F2). If it ends normally, check the communication status with the printer 25 (
F3), and if there is communication with the printer 25, a print instruction is issued (F4), and the process ends (F7). If there is no communication with the printer 25, the display will display "W" meaning standby (F5), and the ENTE
Waits for R key input (F6). During this time, the user can directly instruct the printer to print out the searched pieces. When the ENTER key is pressed after printing is completed (F7), the process exits from the subroutine to execute the next command.

If a print command exists in the memory, the process starts from (F3) in the above flowchart. In this way, even when there is no communication with the printer, instructions in memory can be executed more smoothly. (Embodiment 2) This embodiment is applicable not only to the execution of instructions in the memory input from the keyboard, but also to the RS232C
It also applies to commands from external equipment via communication means such as This reduces communication data and improves overall communication speed.

Furthermore, since the amount of communication data is reduced, malfunctions due to communication errors can be prevented.

[0027] Furthermore, when receiving a command regarding print output, by displaying a standby display and waiting for the user's print output, unlike ignoring the print command or displaying an error message, communication with the printer is Since it is possible to communicate with external devices using the same command format as the search device that can perform the above, it has a significant effect in terms of compatibility.

[0028]

[Effects of the Invention] As explained above, by using the present invention, it is possible to instruct a series of search operations without using a large amount of memory compared to conventional methods.

Furthermore, if the control means changes the print output command to a key input wait command when communication with the printer is not performed, even in an automatic search device that does not have a communication function with the printer. Advance registration to memory,
In addition, functions such as communication control with external devices can be effectively used, and compatibility can be maintained in the command system. This makes it possible to realize a general-purpose search device.
