Description of the Related Art Generally, when a film is developed by a leader transport type automatic film developing apparatus, the leading end of the film pulled out from the cartridge is connected to a leader and the leader is advanced to transfer the film to the film developing section. I am trying to let you.
【0003】ここで、リーダは合成樹脂シートから形成

けられている。Here, the leader is made of a synthetic resin sheet and has flexibility, and feed holes that can be engaged with feed sprockets provided in the film developing section are provided at equal intervals.

取出しに手間がかかり、取出しの際にフィルムが感光す

強固に接続する必要がある。By the way, when the film is removed from the reader during the developing process of the film, the film is stopped in the processing solution and the developing process cannot be performed, and it takes time and effort to take out the film. There is a risk of exposing the film. Therefore, the film needs to be firmly connected to the reader.

に問題がある。The connection between the leader and the film is generally connected by applying a splice tape.
Since it takes time and effort to attach the splice tape and remove it after the development process, and moreover, the film needs to be accurately connected to the leader at a predetermined position, there is a disadvantage that a special work table for splicing is required. Further, since the splice tape cannot be reused, there is a problem in economic efficiency.

ようにしている。In order to solve the above problems, Japanese Patent Application Laid-Open No. 54-158924 proposes a film hook type leader / film connection structure. 4 and 5 show the connection structure, in which two cuts 21 are provided at the rear part of the flexible sheet-shaped reader 20 in the leader transfer direction, and a tongue 22 formed between the cuts 21 is shown.
Is inserted into the opening 24 provided at the tip of the film 23, and the neck portion 25 provided on the tongue 22 is engaged with the side edge of the opening.

ってスムースに搬送させることができる。In the above connecting structure, since no splicing tape is required, it is economical, and since the tongue 22 faces rearward in the transfer direction of the leader 20, the tongue 22 is in the film transfer path of the automatic film developing apparatus. The inconvenience of being caught does not occur, and the leader can be smoothly transported along the film transport path.
【0008】また、スプライステープが不要であるた

とができるという特徴を有する。Further, since the splice tape is not necessary, the film can be accurately connected to the predetermined position of the leader.

る。By the way, in the connecting structure described in the above publication, since the width dimension W 1 of the tongue 22 is larger than the width dimension W 2 of the opening 24, the tongue 22 is bent in the width direction. In this state, the tongue 22 needs to be inserted into and removed from the opening 24, which makes it extremely difficult to connect and disconnect the leader 20 and the film 23.

問題がある。Further, when the film is transported along the film path of the automatic film developing apparatus, the film 23 receives a tensile force at the turn portion of the film path. At this time, since the tongue 22 is directly subjected to the load, the tongue 22 may be deformed and come out of the opening 24, which causes a problem in reliability of connection.
【0011】さらに、フィルム23は舌22の首部分2

傷がつく危険がある。Further, the film 23 is a neck portion 2 of the tongue 22.
Since the film 23 is swingable around 5, the film 23 meanders during transfer and comes into contact with the film path, which may damage the film 23.

振れ止めされる。The first insertion hole 3 and the second insertion hole 4 are sized so that the film 5 can be inserted therein. When the film 5 is inserted into the insertion holes 3 and 4, both side edges of the film 5 are inserted into the insertion holes 3 and 4, respectively. The side edge of the film 5 and the film 5 is prevented from swinging.

1に対してフィルム5を連結することができる。Now, the leading end of the film 5 is inserted into the second insertion hole 4 from the front surface of the reader body 1, and the leading end of the film 5 protruding to the back side of the reader body 1 is inserted into the first insertion hole 3. As a result, the engagement piece 9 is pushed by the tip of the film 5 and the strip 7 is deformed upward. By inserting the film 5 to a position where the engaging hole 8 formed in the film 5 faces the engaging piece 9, engaging the engaging piece 9 with the engaging hole 8, and then pulling back the film 5, The strip 7 is held in a state of overlapping with the surface of the reader body 1, and the tip of the engaging piece 9 is supported by the peripheral edge of the first insertion hole 3 to connect the film 5 to the reader body 1. You can

5を円滑に移送させることができる。The film 5 connected to the reader body 1 is
The leader body 1 leads the sheet to the developing section of the automatic film developing apparatus. At this time, since the strip 7 and the engaging piece 9 face the rear portion in the transfer direction of the reader body 1, there is no inconvenience that the strip 7 and the engaging piece 9 are caught in the film transfer path, and the film transfer path is not affected. The film 5 can be smoothly transferred along the film.

押えバンド11を帯状片7の上面に係合させている。FIG. 3 shows another example of the reader. In this example, a pair of long holes 10 and 10 are formed between the bending position of the strip 7 and the first insertion hole 3, and the strip 7 is inserted into the long holes 10 and 10 to form a pair of long holes. A holding band 11 formed between the holes 10 and 10 is engaged with the upper surface of the strip 7.
【0028】上記のように、帯状片7に押えバンド11

る。As described above, according to the present invention, by inserting the leading end portion of the film from the second insertion hole into the first insertion hole, the engaging piece is engaged with the engaging hole formed in the leading end portion of the film. Can be engaged, and when the film is pulled back after the engagement hole is engaged with the engagement piece, the tip of the engagement piece is moved to the first position.
Since the film is supported by the peripheral edge of the insertion hole and is prevented from coming off, the film can be connected to the leader very easily, and when the film is pushed in, the engagement between the engagement piece and the engagement hole is released. Therefore, disconnection is easy.
【0030】また、係合片の先端部は第1挿入孔の周縁
