DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a development fee display device for photographic film (hereinafter simply referred to as a development fee display device) and a method for displaying the development fee. More specifically, the present invention relates to a development fee display device and a development fee display method capable of easily displaying and issuing a development fee of a photographic film (hereinafter simply referred to as a film) on a price sheet.

[0002]

2. Description of the Related Art Conventionally, the development fee of a film has been calculated from the length and width of a developed film. The development fee is often classified into about two types according to the length of the film due to a difference in the amount of processing solution used and the like. For example, in the case of 135 mm film, if a film of 24 shots or less (film length of 1200 mm or less) is processed, the development fee is A, and a film of 25 sheets or more (film length of 1201 mm or more) is When development processing is performed, the development fee is B. For this reason, an operator who performs development calculates a development fee from the length of the developed film, and issues a price sheet indicating the development fee.

[0003]

However, in the case of a worker who is unfamiliar with issuing a price sheet, there is a possibility that the development fee will be incorrect when issuing a price sheet, and good improvement measures have been awaited. .

SUMMARY OF THE INVENTION In view of the circumstances described above, an object of the present invention is to provide a development fee display device and a development fee display method which do not cause an error in the development fee calculation when a price sheet for film development is issued. And

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of a development fee display apparatus according to the present invention.

FIG. 1 is an explanatory view showing one embodiment of the development fee display device of the present invention, and FIG. 2 is an explanatory view showing another embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a film developing device, which can employ a commonly used structure.
Then, the film F having the magnetic recording section passes through various processing tanks such as a fixing tank and a bleaching tank while passing from the carry-in port 2 to the carry-out port 3, and is developed.

By measuring the length of the surface of the film from the leading end to the trailing end of the film F,
A film detection mechanism 4 for detecting the length of the film F is provided. The film detection mechanism 4 includes a light-emitting sensor 4a and a light-receiving sensor 4b which are arranged on the path of the film F and do not expose the film. However, the present invention is not limited to this, and a limit switch, an ultrasonic sensor, or the like may be used.

The outlet 3 is provided with a magnetic recording mechanism 5 for writing the film length detected by the film detecting mechanism 4 into a magnetic recording portion of the film F. A magnetic recording mechanism 5 capable of writing a film length, a film width, and the like includes a magnetic head and a magnetic recording circuit.

The development fee display device of the present invention is provided with a control mechanism 6 for controlling the transmission of a command for writing as magnetic recording to the magnetic recording mechanism 5 after calculating the detected film length. . As the control mechanism 6, a CPU, a pulse motor, a power supply, a motor driver, or the like can be used.

The film F on which the magnetic recording is written is read by a print developing device (not shown) provided in the film developing device 1 at the time of print development, and the magnetic recording is read out. Control mechanism 6
And an output mechanism 8 for calculating the film development fee and displaying the result on the price sheet 7. As the output mechanism 8, a dot impact printer, an ink jet printer, a laser printer, a thermal printer, or the like is used.

In the present embodiment, the magnetic recording mechanism 5 is provided in the film developing device. However, the present invention is not limited to this. It may be installed in a device that refills the film, or it may be installed in a device that returns the film in a later process to the original cartridge.

Next, another embodiment of the present invention will be described.

In this embodiment, as shown in FIG. 2, an auto-negative mask 9 is used as the film detecting mechanism of the above embodiment. The auto-negative mask 9 comprises a transport roller or a film transport mechanism including a transport arm and a drive motor, and a detector for detecting the length of the film F. An optical sensor, a limit switch, or the like can be used as the detector. The length of the developed film F loaded in the auto-negative mask 9 is detected by a detector while being sent through the auto-negative mask. Then, the detected value is written to the magnetic recording portion of the film F by the magnetic recording mechanism 5. At the time of print development, the control mechanism 6 reads out the information on the length of the film F written in the magnetic recording section, and issues a price sheet 7 on which the film development fee is printed and displayed by the output mechanism 8 based on the information. . The information to be written in the magnetic recording unit may be information necessary for determining a film development fee such as a film width, in addition to information on a film length. The auto negative mask 9 may be provided with a storage mechanism such as a punching machine or a printing device. Thereby, information such as the film length detected by the detector is stored in the storage mechanism, and the output mechanism 8 is used at the time of print development by using the information.
Thus, a price sheet 7 for the film development fee can be issued.

[0025]

As described above, according to the development fee display device and the development fee display method of the present invention, in addition to the length of the film detected by the film detection mechanism, information as a basis for calculating the development fee, Alternatively, the development fee of the film is automatically calculated by the control mechanism based on the symbolized information, and the result can be displayed by the output mechanism at the time of printing. Alternatively, since the length and other information of the film are written on the film by a magnetic recording mechanism, if the print development is performed using the film, the information written on the film is read in advance to charge a development fee. It can be displayed accurately by the output mechanism. Therefore, even an unskilled worker does not make an error in the calculation of the development fee when the price sheet is issued.

An auto-negative mask can be used as a film detecting mechanism. By equipping the auto-negative mask with a storage mechanism, it is possible to directly execute print development based on information stored in the storage mechanism and to display a development fee. In this case, since the magnetic recording mechanism is not used, the equipment cost can be reduced.
