Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has an operation switch for inputting data and setting a predetermined mode in its own device, and is controlled by a camera. The present invention relates to a camera accessory device having a control mode for automatically performing a predetermined operation continuously and a normal mode other than the control mode by the camera. 2. Description of the Related Art Some camera accessory devices have a control mode in which continuous operation is automatically performed under the control of a camera, and a normal mode in which data is input with an operation switch. During the control mode, it is necessary not to operate the operation switch and the like in order to prevent an operation error. As one of the typical camera accessory devices, there is a data back device having a batch printing function. The collective imprint function stores photographing information for each photographed frame at the time of photographing in order to provide photographing data to the user, and when filming is completed for all frames, sends the film and copies the photographed frames. The photographing information is imprinted by positioning the photographing information. In this data back device, the period of the control mode is from the time when the collectively copied frame is positioned at the printing portion and all the shooting information is printed. If the operation button is operated during this control mode, there is a possibility that erroneous data will be imprinted due to a change in the display. [0003] In the printing method using an LCD, printing takes a long time for the following reasons. Since the LCD whose response speed is slow is displayed by changing the display, for example, one line at a time, the total time for changing the display of the LCD for all pieces of photographing information increases. Since the image is projected from the back side of the film base, the time required for irradiating the LCD with the lamp to reach the appropriate exposure amount becomes longer. In order to print a plurality of lines (for example, 25 lines) in one frame, for example, in the case of printing one line at a time, a minute drive must be performed a total of 24 times in one frame. Take it. For the above reasons, since it takes a long time to collectively print, it cannot be said that the photographer never mistakenly thinks that rewinding has been completed and opens the back cover on the way. In addition, when a photographer who is accustomed to shooting in a normal temperature environment performs collective copying in a low temperature environment, for example, the LCD has a large temperature dependency, so that a longer collective copying time is required. For example, what took about 20 seconds to collectively print at a normal temperature may be extended to 1 minute or more. For this reason, if the user is used to the feeling of being used, there is a possibility that the back cover is opened by mistake, as described above. An object of the present invention is that, even if a photographer accidentally presses an operation button or the like during the control mode, a predetermined operation in the control mode does not malfunction, and
Provided is a camera accessory device that prevents a photographer from accidentally opening the back cover by displaying a warning indicating that "immediately copying is being performed" during batch printing in the data back device. It is in. In order to achieve the above object, a camera accessory device according to the present invention has an operation switch for inputting data and setting a predetermined mode in its own device. In a camera accessory device having a control mode and a normal mode other than the control mode by the camera in which a predetermined operation is continuously and automatically performed by a control from the camera side,
The camera accessory device is a data back device having a function of inputting shooting information and the like by operating switches, and having a function of collectively shooting shooting information of each shooting frame onto a predetermined frame. A mode in which a photographing information stored for each photographing frame is transferred to the predetermined frame by a predetermined line in a collective copying sequence. During the collective copying, an input from the operation switch is performed. Pass and continue the batch printing work,
The warning display means is configured to indicate that copying is being performed. The warning display means is realized by providing an LED on the back cover.

be able to. [0007] According to the above configuration, in the control mode, even if the operation button is pressed by mistake, an erroneous input does not occur and the operation is performed normally. In addition, in the data bag device, a warning is displayed during batch printing, so that it is possible to prevent the back cover from being opened by mistake. Embodiments of the present invention will be described below in more detail with reference to the drawings. FIG. 1 is a view showing an embodiment of a camera accessory device according to the present invention. In this example, the accessory device 3 is mounted on the side of the camera 1, and an accessory control unit 6 of the accessory device 3 and a control unit 7 in the camera are electrically connected by a communication terminal 4. In the normal mode, when the button operation unit 5 is operated, data can be input and a mode can be set. When a control command is sent from the control unit 7 on the camera side, a control mode is set and a predetermined operation is automatically performed. For example, if the accessory device is a communication unit, data transmission / reception with a wireless device (not shown) is performed. In this state, for example, when the button of the button operation unit 5 is pressed, the accessory control unit 6 does not accept data input, mode switching, and the like by the button operation unit 5. Therefore, no wrong data is input during the control mode, and a predetermined operation during the control mode does not malfunction. FIG. 2 is a view when the camera accessory device according to the present invention is implemented as a data back device.

When the batch copying is selected, when the shooting of all the frames is completed, the film is fed to position the batch copying frame in the imprinting section 17. Note that when the batch copying is selected, the above-described LED 8 is turned on, and when the copying operation is started, the LED 8 flashes to notify the photographer that the copying is being performed. Next, the control unit 15 sends photographic information of one row, that is, one photographic frame to the main control unit 16 and instructs the main control unit 16 to perform a photographic operation. The main control unit 16 displays the photographing information sent from the control unit 15 on the display unit 9 and drives the imprinting unit 17 to collectively photograph the photographing information and imprint it on the frame. When the printing is completed, the fact is reported to the control unit 15. Based on this report, the control unit 15 sends the shooting information of the next frame, and the main control unit 16 copies the sent shooting information to the next line. When the photographing information of all photographed frames is printed by repeating the above operation, the collective printing is completed. FIG. 4 is a flowchart for explaining the operation of the data back device in FIG. After performing communication with the camera, the main control unit 16 determines whether or not an automatic operation (control mode) for collective imprinting is being performed (steps (hereinafter, referred to as “S”) S401, S402). If you are not in automatic operation,
The button operation unit is scanned (S403), and a button for mode change is pressed (S404), a button for date and time change is pressed (S405), a button for setting change is pressed (S406), and button operation is performed. If there is no button input, the display is changed (S407). If an imprint signal is received from the camera, imprint control is performed (S408), and the original S4

3 through S406, the display information is changed by displaying the photographing information sent from the control unit 15 on the display unit 9 (S407), and the photographing data displayed on the display unit 9 is transferred by the transfer unit 17. . Then, the process returns to step S401, and the same imprinting is performed on the photographing information transmitted next. During imprinting, even if a button operation is performed, no input is accepted because the button operation unit is not scanned. As described above, according to the present invention, when in the control mode by the camera, there is provided a pass means for passing an operation sequence in accordance with an input from the operation switch. Even if it is operated, it is configured not to be accepted and to continue a predetermined operation in the control mode. Therefore, even if the photographer erroneously presses an operation button or the like during the control mode, erroneous data is not input and normal operation can be continued. When the accessory device is a data back device, erroneous information is not imprinted even if an operation button is operated during the imprinting. In addition, since the warning is displayed by the warning display unit during the batch copying, the photographer is not notified that the rewinding has already been completed, and it is possible to prevent the back cover from being opened during the batch copying.
