Abstract

PURPOSE:To store much more information by making the information correspond to each photographic frame by writing the information corresponding to the frame by a magnetic head on the surface of a photographing frame. CONSTITUTION:This camera is provided with a storage means 8 for storing the information at every inputted photographing frame, the magnetic head 10 for writing the information on the magnetic storage part provided on a film, and a writing control means 1 for reading out the information by the storage means 8 and writing the information corresponding to each frame by the magnetic head 10. Hence, character information on each frame stored in an EEPROM 8 can be written on each frame of the film, which possesses a magnetic storage part 62 which can be magnetically written by the magnetic head 10. Thus, the further many pieces of information can be stored corresponding to each frame.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to a camera using a film with a magnetic storage section on which photographic information such as shutter speed and aperture value and text information such as a title are written.

(Background of the Invention) Conventionally, storage means such as EEFROM have been used to store photographic information such as shutter speed and aperture value, and text information such as titles, corresponding to each frame of a film, but this is stored inside the camera. or exist as an external device,
It was possible to connect to the camera. However, in these conventional examples, since a storage means is provided separately from the film, it is difficult to correspond to the film after development.

In addition, as a solution to the above-mentioned problem, character information etc. can be temporarily written into a storage means such as an EEPROM in the camera before shooting, and when the first frame is wound after shooting, the information is read out from the storage means and the relevant It has been proposed to optically imprint it onto the body, but the amount of information that can be readably imprinted on one frame is small, and there is a problem that the desired amount of information cannot be stored. there were.

(Object of the Invention) An object of the present invention is to solve the above-mentioned problems and provide a camera using a film with a magnetic storage unit that can store more information by associating the information with photographic frames. It is to be.

(Features of the Invention) In order to achieve the above object, the present invention provides a storage means for storing information for each photographed frame that is input, a magnetic head for writing information into a magnetic storage section provided on the film, write control means for reading information from the storage means and writing information corresponding to each frame using the magnetic head, whereby information corresponding to the frame is written by the magnetic head onto the surface of the photographed frame; A feature is that writing is performed.

(Embodiments of the Invention) Hereinafter, the present invention will be described in detail based on illustrated embodiments.

FIG. 1 shows an embodiment of the present invention, and in the figure, 1
2 is a photometering circuit, 3 is a distance measuring circuit, 4 is a shutter control circuit, and 5 is an aperture control circuit, all of which are known circuits. Further, 6 is a photometry start switch (SWI), and 7 is an exposure start switch (SW2), which are switches that are turned on at the first stroke and second stroke of one switch member. Reference numeral 8 denotes an EEFROM which is a storage means disposed within the microprocessor 1, 9 a magnetic recording circuit, 10 a magnetic head for storing photographic information on a film having a magnetic storage section, which will be described later, and 11 a photographing device. Key human power section for entering character information such as location and title, 12
1 is a display section, and 13 is a RAM which is an external storage means.

Next, the operation will be explained using the flowchart shown in FIG.

When the film is loaded into the camera, an automatic loading (AL) operation is performed in step 101.Then, in step 102, the specified number of frames of the film are read. In the next step 103, character information input from the key input section 11 is stored in the EEFROM in the microprocessor 1.
Store in 8. Then, in step 104, it is checked whether the photometry switch 6 (SWl) is on. As a result, if it is turned on, the process proceeds to step 105, where the photometry circuit 2 and distance measurement circuit 3 are operated, and photometry and distance measurement operations are performed based on information obtained by these circuits. On the other hand, if it is not turned on, the process returns to step 104.

In step 106, it is checked whether the exposure start switch 7 (SW2) is on. As a result, if it is turned on, the process proceeds to step 107, where the shutter control circuit 4 and the aperture control circuit 5 are operated, and an exposure operation is started. On the other hand, if it is not on, the process returns to step 104. In the next step 108, film winding is started, and at the same time character information is read out from the EEPROM 8 along with photographing information such as shutter speed and aperture value, and the magnetic recording circuit 9 is activated. Then, the information is recorded in a magnetic storage section on the film, which will be described later, by the magnetic head 10, and the process returns to step 104.

FIG. 3 shows a film used in the camera of the present invention. In the figure, 60 is a perforation used during film feeding, and 61 is an exposed surface of the film. Also 6
Reference numeral 2 denotes a magnetic storage section, and the magnetic head 10 is placed on the surface of the magnetic storage section 62, and the above-mentioned photographic information and character information are magnetically written by this magnetic head 10.

FIG. 4 is a block diagram showing the main parts of the circuit shown in FIG.
The storage means 52 stores character information in the EEFROM 8,
A magnetic recording circuit 9 in which an input means 51 writes photographic information and text information to be inputted by a writing means 53 to the key manual section 11.
The release instruction means 55 corresponds to the exposure start switch 7 in the magnetic head 10 and the magnetic head 10, respectively.

According to this embodiment, the character information of each frame stored in the EEPROM 8 is written to each frame by a magnetic head on the film having the magnetic storage section 62 which is magnetically writable, so that more information can be stored. , it becomes possible to store the information in correspondence with each piece.

(Effects of the Invention) As explained above, according to the present invention, there is provided a storage means for storing input information for each photographed frame, a magnetic head for writing information into a magnetic storage section provided on a film, write control means for reading information from the storage means and writing information corresponding to each frame using the magnetic head, whereby information corresponding to the frame is written by the magnetic head onto the surface of the photographed frame; Since I started writing,
It becomes possible to store more information by associating the information with photographic frames.
