Abstract

PURPOSE:To optionally rewrite data which should be recorded in an image recording means by a user in advance by providing a RAM to which the data is transferred and which is capable of electrically replacing and holding the data, and a data recording means. CONSTITUTION:The content of the RAM 62 is the data which is set in the RAM 62 in advance and corrected by an imprinting data setting and correction circuit 71, or the data transferred from an EEPROM 61. Whenever a display changeover switch 66 is turned on, the data stored in the RAM 62 by the imprinting data setting and correction circuit 71 is successively displayed on a display circuit 72. When the desired data is selected, which dot may be corrected out of them is selected by a selection switch 67. Whenever a correction switch 68 is turned on in the state where a certain dot is selected, turning on/off for setting the dot is alternately switched. In the case that the data which is written in the RAM 62 is required to remain even in the case that the power source is turned off, the data in the RAM 62 is transferred to the EEPROM 61 by a memory control circuit 70 by turning on a switch 65.

Switch for transferring to M62, 65 is RAM62
The 1m setting data is stored in EEPROM611. A switch 66 for transferring R is displayed on the display circuit 72.
A display changeover switch 67 is used to sequentially change the data in the RAM 62, a modification part selection switch 67 is used to select a modification part of the content of the RAM 62 data displayed on the display circuit 72, and a modification part selection switch 68 is selected by the modification part selection switch 67. This is a correction switch for correcting the location. The display circuit 72 is a display circuit composed of a dot matrix LCD or the like for displaying the data contents of the RAM 62.

FIG. 2 is a diagram showing a card 20 containing the EEPROM 6] loaded into the back cover (data imprinting device) of the camera 21. By replacing the card 20, It is also possible to replace the EEPROM 61. Therefore, although not shown, the EEPRO
M61 (card 20) has a connection terminal that is connected to other circuits in the data imprinting device, and needless to say, other circuits in the data imprinting device have terminals to which the connection terminal is connected. Equipped.

Next, the operation will be explained according to flowchart I. of FIG.

When the switch 7 is turned on, the microcomputer 2 first operates a distance measurement and photometry circuit (not shown) to start photometry and distance measurement. Next, when the switch 48 is turned on, the information obtained by the distance measuring operation is output to the lens barrel control circuit 3, and the lens barrel control circuit 3 operates the lens barrel (not shown) based on this information. When the operation is completed, the information obtained by the photometry operation described above is output to the exposure control circuit l. As a result, a shutter (not shown) is controlled and exposure of the film is started.

When the exposure of the film surface is completed, a winding signal is output to the motor control circuit 4 to wind the film, and winding of the exposed film for one frame is started.

In synchronization with the film winding operation, the LED 5 is driven by the LED driver 63 according to the contents of the RAM 62, and the data in the RAM 62 is imprinted onto the film.

Here, the contents of the RAM 62 are data set or modified in advance in the RAM 62 by the imprint data setting/correction circuit 70 or data transferred from the EEFROM 61.

The data set and corrected by the imprint data setting/correction circuit 71 is as follows.

Each time the display changeover switch 66 is turned on, the imprint data stored in the RAM 62 is sequentially displayed on the display circuit 72 by the imprint data setting/correction circuit 71. Once the target data is selected, the user selects which dot in the data is to be modified using the modification location selection switch 67. this is,
Each time the correction point selection switch 67 is turned on, the dots blink in sequence to indicate that the correction point is to be selected. Next, the modification point selection switch 67 is configured so that each time the modification switch 68 is turned on while a certain dot is selected, the settings for that dot are alternately switched on and off.

In this way, data including character information such as place names and seasons is written into the RAM 62.

The data transferred from the EEPROM 61 to the RAM 62 is as follows.

As mentioned above, the data written in the RAM 62 can be used for imprinting as is, but if you want to keep the data even if the power is turned off, turn on the switch 65 to turn on the memory control circuit 70. Transfer the data in RAM 62 to EEPROM 61.

When the data transferred from the RAM 62 is to be copied to the EEPROM 61, by turning on the switch 64, the memory control circuit 70 transfers the data from the EEPROM 61 to the RAM 62, and the data is copied as described above. Become.

In addition, data can be sent directly to E E without going through RA Li 62.
Write to P ROM 61, or write to EEPRO
M6] may be imprinted, but E E P
There is a problem that writing and reading data to ROLi takes more time than writing and reading data to RAM.In particular, if you read data from EEPROM during imprinting, you will not be able to keep up with it, and the EEPROM The problem with durability is that, as mentioned above, data is stored in RAM and stored in EEPRO only when necessary.
This problem can be solved by using M.

According to the above embodiment, by adding the EEPROM 61 to the imprinting module circuit, characters, information, and marks that could not be imprinted in the past can be easily imprinted, and they can also be rewritten. It is now possible to design text to suit your tastes, allowing you to make the camera even more personalized to you.

On the other hand, although the above embodiment shows an example in which the EEPROM 61 is replaceable, it is of course possible to obtain the same effect as described above even if the EEPROM 61 is of a non-replaceable type.

Further, although EEPROM is used in the above embodiment, it goes without saying that the present invention can be similarly applied even if this is replaced with a similar memory means such as an IC memory card.

Further, in the above embodiment, data is imprinted on a film, but it goes without saying that the present invention is equally applicable to recording data on other types of image recording means.

〔Effect of the invention〕

As explained above, according to the present invention, the data to be recorded in the image recording means can be arbitrarily rewritten by the user in advance, and there is no need for the trouble of writing data each time before photographing. It is possible to provide a camera data device that does not require time to read data, and its effectiveness is extremely high.
