Abstract

PURPOSE:To prevent unwanted data from being written in each recorder by setting simultaneous use information to each recorder by a setting-means in the case of simultaneously using the respective recorders. CONSTITUTION:When camera units 4 and 5 are mounted on a main body, it is checked whether a reader is transmitted or not. Just before or after this reader transmission is executed, the simultaneous recording information (date data) are written in memory parts 4a and 5a provided at the camera units 4 and 5. After this write is executed, single photographing or simultaneous photographing while mounting the other unit can not be executed unless a CPU 3 judges the simultaneous recording information is same. In this case, a judging means 3b automatically judges whether the simultaneous use is enabled or not while referring to each simultaneous use information stored in respective recorders 4a and 5a in the case of simultaneously using the respective recorders 4a and 5a.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information recording device in which at least two recording devices can be used in parallel.

[0002]

2. Description of the Related Art Conventionally, a double-head flatbed type camera, a double-head rotary type camera,
A computer device or the like provided with a double drive type recording device has been put into practical use.

Among them, in the double-head flatbed type camera, each camera is loaded with a film and used until the film is empty, and another camera cannot be used during shooting.

The double head rotary type camera and the double head flat bed type camera are almost the same.

Further, in the computer system, 1
In order to retain the same contents after using one floppy disk (FD), a method of copying a backup to a new floppy disk by two recording devices is generally adopted.

[0006]

However, in the above double-head flat-bed type camera and double-head rotary type camera, each of the double-head flat-bed type cameras and the double-head rotary type cameras to be used is used in the case of a photographing mode in which many other camera heads are used during use. It is necessary for the user to write down the camera number etc. in advance.
In some cases, the camera is used as a pair (simultaneous shooting) after being taken in combination with another camera, and the contents are mixed and it is impossible to determine which camera is a pair shooting group.

Also in the case of a personal computer, after the copying process and the use of another floppy disk,
There is a problem in that it is necessary to compare and collate the contents of the floppy disks individually to search for floppy disks having the same contents, which increases the search load on the user.

The present invention has been made to solve the above-mentioned problems, and when the recording devices which can be used in parallel are used at the same time, the registered simultaneous use information is compared and collated to determine whether or not the simultaneous use is possible. An object of the present invention is to obtain an information recording device that can automatically determine

[0009]

An information recording apparatus according to the present invention comprises setting means for setting simultaneous use information in the recording apparatus when the recording apparatuses are used simultaneously, and simultaneous use information set in each recording apparatus. A determination means for automatically checking whether or not simultaneous use is possible by collating is provided.

Further, the setting means is configured to simultaneously set the date / time information or the simultaneous use information composed of a part of the date / time information in each recording device.

Further, the setting means is configured such that each recording device can be set by attaching the single-usability information to the simultaneous use information.

[0012]

In the present invention, since the setting means sets the simultaneous use information to each recording device when the recording devices are simultaneously used,
When the recording devices are used at the same time, the determination means collates the simultaneous use information set in the recording devices to automatically determine the simultaneous use availability, and prevents unnecessary data writing to the recording devices.

Since the setting means sets the simultaneous use information composed of the date / time information or a part of this date / time information to each recording apparatus at the same time, the simultaneous storage information of each recording apparatus used at the same time is the other simultaneous use information. You can limit the situation that matches with.

Further, the setting means sets each recording device with the single-usability information attached to the simultaneous-use information,
It is possible to selectively allow individual use of each recording device that can be used simultaneously.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram for explaining the structure of an information recording apparatus showing an embodiment of the present invention, which corresponds to, for example, an apparatus for recording photographing information of a pair of cameras mounted on a camera unit. To do.

Reference numeral 1 is a clock, which is constantly driven by a backup power supply 2 and is updated with time data (year, month, day,
(Hour, minute, second) is sent to the CPU 3. The CPU 3 controls each unit by a program (including each procedure of a flowchart described later) written in a storage unit (not shown).
Numerals 4 and 5 are camera units, each of which is loaded with a microfilm, and is driven by a drive system 8 which is driven by the control of the CPU 3 so that the microfilm can be simultaneously photographed. A display unit 6 displays information from the key unit 7, control information, error messages, and the like. 4a, 5a
Is a memory section in which the number of frames already taken regarding the microfilm in the cameras mounted in the camera units 4 and 5 is written, and the area in which simultaneous use information according to the usage form, for example, date and time data is written is confirmed. Has been done.

In the information recording apparatus having such a configuration, the setting means 3a includes the recording apparatuses (memory sections 4a and 5a).
Etc.), the simultaneous use information is set in each recording device at the same time. Therefore, the determining means 3b automatically determines whether or not the simultaneous use is possible by collating the simultaneous use information stored in each recording device when the recording devices are simultaneously used. Therefore, unnecessary data writing to each recording device is prevented.

Since the setting means 3a sets the simultaneous use information consisting of the date / time information or a part of this date / time information to each recording apparatus at the same time, the simultaneous storage information of each recording apparatus to be used at the same time is used for other simultaneous use. You can limit the situations that match the information.

Further, the setting means 3a can set each recording device by adding the single-usability information to the simultaneous-use information, and selectively allow individual use of the simultaneously-usable recording devices. Become.

First, when the camera units 4 and 5 are mounted on the main body, it is checked whether or not the reader is sent. Here, the leader represents a fog portion at the leading end of the microfilm when the microfilm is loaded, and the leader is ready to be photographed when the unexposed portion is wound on a film winding portion (not shown) and set in the photographing portion. The memory unit 4 provided in the camera units 4 and 5 with the simultaneous recording information (date and time data) immediately before or after the leader feeding is executed.
a and 5a. After this writing is performed, thereafter, unless the CPU 3 determines that the simultaneous recording information (date and time data) is the same, it is not possible to shoot alone or at the same time with another unit attached.

Simultaneous recording information (date and time data) of both parties
If is blank, the above determination is not performed. As a result, when the simultaneous recording information is written in the memory units 4a and 5a shown in FIG. 1, the contents of the microfilm in the cameras mounted on the camera units 4 and 5 become the same, and the microfilm is extracted from the main body on the way. However, it is possible to avoid the situation where another image is imprinted. In addition, date and time data (year, month,
All of the days, hours, minutes, and seconds) may be managed and used, or may be configured by a part of the date and time data (for example, hours and seconds). Also, the accumulated data may be used. This is such that simultaneous use information is accumulated by "1" each time it is used so that the same code is not obtained. Further, each of the means 3a and 3b may be configured as independent hardware.

This eliminates the need for the timepiece 1 and further reduces the memory capacity. However, it may be the same synchronous recording information as that recorded in other models, so caution is required in data management. Furthermore, a random function may be used and may be appropriately selected according to the probability of matching and the necessity.

FIG. 2 is a flow chart showing an example of the simultaneous information management processing procedure in the information recording apparatus of the present invention.
In addition, (1) to (10) indicate each step.

First, it is determined whether or not two cameras and recording media are set (1). When two cameras and recording media are set, simultaneous recording information is read.
(2) Determine whether or not the simultaneous recording information has already been registered (3) .If YES, determine whether the registered simultaneous recording information matches (4) .If YES, select the simultaneous recording sequence. If it is NO, the message of operation prohibition is displayed on the display unit 6 (5), and if reset is input from the key unit 7 (6), if YES, the process returns to step (1).

On the other hand, in the step (3), in the case of NO, it is judged whether or not the simultaneous recording information is written (7), and if YES, the synchronous recording information is written in the memory sections 4a, 5a etc. (8).
, NO, the normal recording sequence is started (10).
The contents of the memory units 4a and 5a are cleared when the film is taken out from the camera units 4 and 5.

In the above embodiment, the camera unit 4,
Although the case where the memory units 4a and 5a are provided in 5 to manage the synchronous recording information has been described, when the camera is attached to the camera units 4 and 5, the identification mechanism (the projection unit row is provided to input the code) is used. A configuration in which the camera number can be input may be used to substitute the memory units 4a and 5a for the internal memory of the CPU 3. In this case, the simultaneous recording information is written in the address designated by the camera number. The simultaneous recording information may be the camera number instead of the date and time data.

FIG. 3 is a block diagram for explaining the structure of an information recording apparatus showing another embodiment of the present invention, which corresponds to the case of a floppy disk apparatus of a computer apparatus.

The clock is constantly driven by the backup power supply 12 and is updated with time data (year, month, day, hour,
(Minutes, seconds) are sent to the CPU 13. The CPU 13 controls each unit by a program (including each procedure of a flowchart described later) written in a storage unit (not shown).
14 and 15 are floppy disks, and drive 13a,
14a, desired information and simultaneous recording information are read and written. When the floppy disks 14 and 15 are formatted, the CPU 13 secures an area for writing simultaneous recording information and initializes it. Then, at the time of the simultaneous recording request, the CPU 13 simultaneously activates the drives 13a and 14a to write the simultaneous recording information (date and time data). In addition, 16 is a display part and 17 is a key unit.

[0029]

As described above, according to the present invention, the setting means for setting the simultaneous use information in the recording apparatus at the time of simultaneous use of the recording apparatuses and the simultaneous use information set in each recording apparatus are collated and simultaneously. Since the determination means for automatically determining the availability is provided, it is possible to automatically identify the recording apparatus set that can be used simultaneously, and when the recording apparatus that can be used alone is set by an inadvertent operation, The simultaneous recording cannot be detected without fail and the simultaneous activation can be surely restricted.

Further, since the setting means is configured to simultaneously set the date / time information or the simultaneous use information consisting of a part of this date / time information to each recording device, the probability of being the same data is extremely low and the simultaneous storage is possible. The reliability of information can be increased.

Further, since the setting means is configured such that each recording device can be set by attaching the single-usability information to the simultaneous use information, the individual use of each recording device can be permitted.

Therefore, even if the use environment is set such that the recording devices satisfying the condition of simultaneous use and the recording devices for single use coexist, the simultaneously usable recording devices can be automatically recognized and specified. The conventional work load can be reduced. Further, there is an effect that it is possible to surely restrict data writing such that other information is mixed in each recording device during simultaneous recording.
