DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a photographic processing apparatus and a method for reading and writing a magnetic recording section.

[0002]

2. Description of the Related Art A magnetic head is not necessary for a photographic processing apparatus for processing a film, since a magnetic information track is not included in a film currently on the market. However, when processing a magnetic film containing tracks of magnetic information, a magnetic head is required for the photographic processing apparatus, and the film and the magnetic head must be in close contact. Therefore, a photographic processing apparatus for processing a magnetic film is provided with a fixed retainer for bringing the film into close contact with the magnetic head.

[0003]

However, when the film is pressed strongly by the above-mentioned pressing, the adhesion between the film and the magnetic head is improved, but the resistance at the time of inserting the film increases, and the pressing and the magnetic head at the time of inserting the film become hard. There was a great concern that the film could get stuck in between.

[0004] The present invention has been developed in view of the above problems, and its object is to reduce the resistance at the time of film insertion and to appropriately increase the adhesion strength of the magnetic head to the film. So that you can press
It is another object of the present invention to provide a photographic processing apparatus and a magnetic recording unit reading / writing method capable of smoothly reading magnetic recording information on a film with a magnetic recording unit or writing recording information on the film.

[0005]

The present invention has the following configuration in order to effectively achieve the above object. That is, the magnetic recording section reading and writing method of the present invention according to claim 1 is a method of reading magnetic recording information of a film with a magnetic recording section to be conveyed by a magnetic head or writing recording information to the film.
The film is constantly pressed by the pressing means from the back side of the film conveyed below the magnetic head, and the movable member movable by the operation of the solenoid is connected to the magnetic head via the operating member, and when the solenoid is operated. The distance between the movable member that moves up and down simultaneously through the operating member and the magnetic head is kept constant, and when it is detected that the film is conveyed to the magnetic head side by the conveying roller, the solenoid is operated to move the magnetic head to the film. Press against
Further, when the film is transported from the magnetic head to the transport roller downstream of the film transport path, the magnetic head is further pressed against the film to read the magnetic recording information of the film,
Alternatively, the recording information is written on a film.

[0006]

According to the structure of the first aspect,
With the magnetic recording unit film by the roller to the magnetic f head side
When a magnetic head detects that
Pressing the film and transporting the film from the magnetic head
When the film is transported to the rollers on the downstream side of the path,
The head further presses the film with magnetic recording
By reading the magnetic recording information of this film accurately,
Recorded information can be accurately written on the film.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described below with reference to FIGS. In the figure, 1 is a first transport roller,
2 is a negative brush, 3 is a magnetic head, 4 is a solenoid, 5
Denotes a perforation detection sensor, and 6 denotes a second transport roller, which is arranged from the first transport roller 1 to the second transport roller 6 in the order shown in the figure.

A is a film with a magnetic recording portion (hereinafter, referred to as a film). The film A is provided between a first transport roller 1 and a negative brush 2, a magnetic head 3, a solenoid 4, a perforation detection, as shown in FIG. It is arranged so as to pass between the sensor 5 and the second transport roller 6. When the film A is pressed against the two pairs of transport rollers 1 and 6, the magnetic head 3 slightly pushes the film A from a tangent line of each pair of the opposite transport rollers 1 and 6.

Further, a pressure welding tool 7 is provided so as to face each of the magnetic heads 3. This pressure welding tool 7
The contact plate 8 is constantly pressed toward the magnetic head 3 by the bias of the spring 7a. Each magnetic head 3 is connected at its rear part 3a by a plane quadrangular operating member 9. The actuating member 9 is connected to the movable member 4a of the solenoid 4 as shown in the figure, and when the solenoid 4 is energized, the movable member 4a
The state shown in FIG. 1 is drawn toward the solenoid 4 as shown in FIG. As a result, the operating member 9 also moves in the direction of the arrow in FIG. 2, and each magnetic head 3 connected to the operating member 9 with the rear part 3a is pushed from the rear part, and the spring 7a of the pressing member 7 is pressed. The film A is pressed against the solenoid 4 by an appropriate pressing force against the rebound. With respect to the film A sandwiched between the magnetic head 3 and the contact plate 8, the film A can be sandwiched with an appropriate strength by the resilient action of the spring 7a of the pressing member 7.

Then, after the leading end of the film A is pressed against the first transport roller 1 and passes through the negative brush 2, the magnetic head 3, and the perforation detection sensor 5, the second transport roller 6
Is passed, the number of pulses is counted and predicted by the perforation detection sensor 5, and the solenoid 4 (or motor) is operated to move the magnetic head 3. When the magnetic head 3 moves, a certain tension is generated in the film A, and the magnetically recorded information on the film A can be read or written accurately.

[0011]

As described above, the magnetic recording according to the present invention is performed as described above.
According to the recording and reading method,
Read recorded information accurately, or correct magnetic information on the film.
Can be written reliably. Therefore, compared to the conventional
The reading and writing performance of the recording unit is greatly improved.
