Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a washing and drying apparatus for a film reader, and more particularly to a film for automatically washing and drying a film reader used when conveying a photographic film in an automatic processor. The present invention relates to a cleaning and drying device for a leader.

[0002]

2. Description of the Related Art In an automatic processor for developing an exposed photographic film, the photographic film is conveyed through a developing solution, a fixing solution and a cleaning solution in order, and then dried. ing. When a photographic film is transported by an automatic developing machine, a film reader made of polyester or the like for leading the photographic film is used.

In this film reader, a plurality of holes for engaging teeth or sprockets of a conveyor belt provided in an automatic developing machine are regularly formed in a central portion, and a plurality of holes are formed at a rear end portion in a conveying direction. The photographic film is formed with a detachable engaging portion.

In order to develop a photographic film with an automatic developing machine, the film reader is guided and transported in the automatic developing machine in a state where the photographic film is engaged with the engaging portion of the film reader.

The film leader discharged from the automatic developing machine is reused for developing other undeveloped photographic films. However, if the film reader is used as discharged, the processing solution is mixed and fogging occurs. For example, the film reader needs to be washed and dried.

Conventionally, it has been common practice to manually wash by hand with tap water or the like and air dry, and it takes a long time to wash and dry.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and it is an object of the present invention to provide a film reader cleaning / drying apparatus capable of cleaning and drying in a short time by automatically processing the film reader. With the goal.

[0008]

In order to achieve the above-mentioned object, the present invention provides a film reader comprising a plurality of film readers used for conveying a photographic film in a developing machine.
A feeding unit for feeding the stacked film readers one by one, a cleaning unit for automatically cleaning the film leader sent from the feeding unit, and automatically drying the film reader cleaned by the cleaning unit. Drying section,
And a transport device that transports the film reader sent from the sending unit so as to pass through the washing unit and the drying unit in this order.

[0009] In the present invention, a plurality of film readers are arranged on the sending section and are sent out one by one from the sending section. The film reader sent out from the sending unit is conveyed by the conveying device so as to pass through the washing unit and the drying unit in this order. Then, the film reader is automatically washed in the washing section and automatically dried in the drying section.

[0010]

Embodiments of the present invention will be described below in detail with reference to the drawings.

As shown in FIGS. 1 and 2, in the present embodiment, a sending unit 10 for sending out film readers L arranged one by one, a washing unit 12 for automatically washing the film reader, a washing unit A drying unit 14 for automatically drying the film leader washed in the unit, and a transport motor 16 as a transport device for transporting the film leader are provided.

The feeding section 10 is provided with a cassette 24 rotatable about a shaft 20 on the base end side and whose front end side is urged counterclockwise in FIG.

A pair of delivery rollers 28 made of rubber or the like and fixed to a shaft 26 are arranged on the tip side of the cassette 24. A gear is attached to the shaft 26 via a one-way clutch. This gear is connected to a delivery motor 30 via a chain, and the delivery roller 28 is rotated by the delivery motor 30 only in the film reader delivery direction. In addition, cassette 2
A microswitch 32 for detecting passage of a film reader is attached to the downstream side in the transport direction of No. 4.

On the downstream side of the cassette 24 in the transport direction, transport roller pairs 34 and 36 for sandwiching and transporting the film reader are arranged. A guide plate 35 is arranged between the pair of transport rollers 34 and 36.

The washing section 12 has a washing tank 38 for storing water.
Is provided. In the washing tank 38, an overflow pipe 40, a drain pipe 42 and a drain valve 43 are provided.
Is attached. In the washing tank 38, a brush roller pair 44 for nipping and cleaning the transported film reader is arranged. The brush rollers of the brush roller pair 44 rotate in mutually opposite directions.

On the exit side of the brush roller pair 44, a guide plate 46 whose lower side is immersed in washing water in the washing tank 38 and whose upper side protrudes from the washing tank 38 and is inclined is disposed. Is provided with a transport roller pair 48 in the vicinity of.

A fan 50 is disposed on the bottom of the drying unit 14, and a heater 52 is disposed above the fan 50. Therefore, with the heater 52 turned on, the fan 50
When driven, hot air is generated. A pair of transport rollers 54 and 56 are arranged in the transport path above the heater 52.
A pair of guide plates 58 for nipping and guiding the edge of the film reader is disposed between the pair of transport rollers 54 and 56. Reference numeral 60 denotes a heat-sensitive portion used when adjusting the temperature of the heater to a constant value, and reference numeral 62 denotes a discharge tray from which the film reader is discharged.

Each of the transport roller pairs and the brush roller pairs is driven by a transport motor 16.

Reference numeral 64 is a main switch, 66 is a ready lamp, and 68 is a start switch.

The operation of this embodiment will be described below. First, when the drain valve 43 is closed and washing water is stored in the washing tank 38 and the main switch is turned on, the ready lamp 66 is turned on after a predetermined time has elapsed. The cassette 24 is rotated against the urging force of the spring 22, and the stacked film leader is set so as to be sandwiched between the bottom surface of the cassette 24 and the delivery roller 28. When the start switch 68 is turned on, the sending motor 30 and the transport motor 16
Is driven, and the film reader is sent out from the sending unit 10 one by one. The fed film leader is immersed in washing water in the washing tank 38 of the washing unit 12 and washed by the brush roller pair 44. Then, the film reader washed in the washing unit 12 is dried by hot air in the drying unit 14.

In the above description, an example in which cleaning is performed using a brush roller has been described. However, the present invention is not limited to this, and cleaning may be performed by spraying washing water.

[0022]

As described above, according to the present invention, since the washing and drying are automatically performed, the effect that the film reader can be washed and dried in a short time can be obtained.
