Abstract

PURPOSE:To facilitate the completion of an accommodating operation such as rewinding a film and to improve the operability of the cartridge by making the part holding a cartridge movable together with the cartridge. CONSTITUTION:When the cartridge 1 is pushed into a holder 22, the holder 22 moves and the light of the sensor S is shielded by a light shielding panel T, thereby detecting that the cartridge 1 is mounted. A locking arm a is pulled by a spring 27 simultaneously, so that the cartridge 1 and holder 2 are locked by the leading edge C of the arm. When the film F is rewound after it is pulled and retrieved, a solenoid pulls back the arm C to release the lock between the holder 22 and the cartridge 1. The holder 22 moves by means of the spring 26 up to the position where the edge of the cartridge 1 is exposed from its over. Thus, the completion of rewinding is easily ascertained, and the operability of the cartridge is improved.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a film transport device for automatically extracting and transporting a film, such as a roll of microfilm, contained in a removable cartridge.

(Prior Art) Conventionally, in devices that search for information on films such as microfilm, after the information search for the film conveyed from the reel is completed, the reel is rotated in the opposite direction so that the original state is restored. The film is then wound onto the reel.

There are two types of devices in which the cartridge for storing the film remains locked in the holder, which is the loading section, after winding of the film is completed, and the other type in which the cartridge for storing the film remains locked in the holder, which is the loading section. It is known to detect the end of winding and push the cartridge out of the holder.

FIG. 3 shows a conventional example of a type in which the cartridge is pushed out from the loading section. In the figure, the microfilm lO1 wound on the reel 100 is attached to the cartridge 1.
It is rotatably attached to 02. The conveyor belt lO3 is moved by the pulley 105 in the direction of arrow C1, and the swinging arm 106 is rotated in the direction of arrow A I * B1 to press the conveyor belt 103 against the microfilm lot.
or leave. Further, the conveyance pulley 107 is rotationally driven in the direction of arrow D1, and rotates the separation gear 109 in the direction of arrow E1 via belt lO8. The pinch roller 110 and the transport pulley 107 pinch and transport the microfilm 101.

Here, the cartridge 102 is installed into a holder (not shown) from the left side in the figure, but at that time, the right side of the cartridge 102 pushes the light shielding plate 111 in the same direction as the arrow, thereby blocking the light from the sensor 112. This confirms that the cartridge 102 is installed. The light shielding plate lll is biased in the direction opposite to the direction of the arrow when the cartridge 102 is loaded or loaded by a spring 113 whose one end side is fixed to the main body of the apparatus, so as to press the cartridge 102 in the same direction. In this case, since the cartridge 102 is locked by the rotatable lock arm 114, it is locked at a predetermined position without being pushed back outward.

When the information search etc. are completed and the microfilm 101 is wound onto the reel 100 again, the lock arm 114 moves in the direction of the arrow to disengage from the cartridge 102, and the biasing force of the spring 113 causes the lock arm 114 to move in the direction of the arrow. The cartridge 102 is pushed out.

(Problems to be solved by IJI) However, in the case of such a conventional example, there were the following problems. That is, first of all, if the cartridge is not pushed out even after film winding is finished, it is difficult to confirm that the winding operation has finished, and there is a risk of the cartridge being taken out while the device is in operation. This also has the drawback that the waiting time before moving on to the primary operation becomes longer.

On the other hand, in a device of the type that pushes out the cartridge after winding the film, a light shielding plate 11 as shown in FIG.
1 presses a local part of the cartridge 102, which may cause deformation or damage to the cartridge 102. Also, depending on the position where the cartridge 102 is pressed, it may become distorted, resulting in the cartridge not moving within the holder. was.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art.The purpose of the present invention is to facilitate confirmation of completion of film rewinding operation and to improve operability of a cartridge storing the film. An object of the present invention is to provide an improved film conveying device.

(Means for Solving the Problems) In order to achieve the above object, in the present invention, a roll-shaped film stored in a cartridge is taken out from the cartridge and conveyed, and a target frame is searched for. In the film conveying device for storing the film in the cartridge again after the film is finished, the holding part for holding the cartridge is movable together with the cartridge.

(Function) In the present invention having the above configuration, since the cartridge that stores the film is movable, it is easy to confirm that the film is finished when the film is stored in the cartridge again by rewinding or the like.
