Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a photosensitive material conveying mechanism, a pair of guide members for separately guiding both ends in the width direction of the photosensitive material conveyed by the conveying mechanism, and a guide by the guide member. Providing guide width adjusting means capable of changing and adjusting the width, and reference position setting means for setting a reference position of the guide member, and moving the guide member from the reference position to reduce the guide width of the photosensitive material. The present invention relates to a transport unit of a photographic processor configured to be settable to a width corresponding to the width.

[0002]

2. Description of the Related Art The above-described guide width adjusting means includes, for example, a pulse motor for moving a pair of guide members in a distance direction,
A control device for controlling the pulse motor is provided, and the guide member is positioned at a reference position (hereinafter, “home position”).
(Hereinafter referred to as "a"), and then the guide members are fed by a predetermined amount so as to approach or separate from each other, thereby setting a desired guide width.

The position of the guide member at the home position is detected by a position sensor or the like. If there is a mounting error in the position sensor or the like, the guide member is set to a desired guide width even if the guide member is fed a predetermined amount from the home position. You can't do that.

Therefore, when the assembling of the transport unit is completed, the guide member is fed by a predetermined amount from the home position to measure the guide width and to check whether or not the guide width has reached a desired value.

If the measured value is different from the desired guide width, for example, a correction is made to increase or decrease the number of transport pulses of the pulse motor, thereby changing the feed amount from the home position to obtain the desired guide width. (If the measured value matches the desired guide width, there is no need for correction).

Conventionally, whether or not the guide member has a desired guide width as described above has been measured by applying a scale or the like to the guide member.

[0007]

However, since the photosensitive material transport path is located at a complicated place in the transport unit, it is difficult to measure the guide material by applying a scale or the like to the guide member. Was hanging. Also,
At the time of measurement, the scale is often read when viewed from an oblique direction, so that a reading error is likely to occur.

It is conceivable to load the photosensitive material into the guide member and check the guide width. However, there is a problem that the photosensitive material is bent, and it is difficult to check whether the guide width is a desired width. Have difficulty.

An object of the present invention is to check whether or not both guide members can be set to a desired guide width.
The point is to make it easy and accurate.

[0010]

The constitution, operation and effect of the invention according to claim 1 are as follows.

[Structure] In the transport unit of the photographic processing machine described at the beginning, an interlocking portion that moves integrally with the guide member and a fixed portion whose position in the guide width direction is fixed are along the guide width direction. The interval in the direction can be measured by a measuring operation from outside the unit.

[Operation] For example, when it is desired to set the guide width of the guide member to 130 mm (other values may be used), it is necessary to set the guide member at a position where the guide width becomes 130 mm. The transport unit is manufactured in such a manner that the distance between the interlocking portion and the fixed portion in the guide width direction is, for example, 40 mm (other values may be used).

When the assembling of the transport unit is completed, the guide member is fed by a predetermined amount from the home position as a reference position, and it is confirmed whether or not the desired guide width is 130 mm. In this case, the distance between the interlocking portion and the fixed portion in the guide width direction is measured from outside the unit.

If the measured value is different from 40 mm, the guide width is not 130 mm, so that the feed amount of the guide member (the predetermined feed amount) is corrected. Thereby, the guide member can be set to a desired guide width. If the measured value is 40 mm, the correction does not need to be performed.

As described above, in the means for measuring the distance between the interlocking portion and the fixed portion from the outside of the transport unit, even if the transport path of the photosensitive material is located at a complicated place in the transport unit, the measurement is performed. Can be easily performed without disturbing each component.

In addition, when measuring on a scale, the scale of the scale can be read from a right angle direction, thereby preventing a reading error from occurring.

[Effect] Accordingly, an inspection is performed to determine whether or not both guide members can be set to a desired guide width.
Now you can do it easily and accurately.

The structure, operation and effect of the invention according to claim 2 are as follows.

In the configuration according to the first aspect of the present invention, the interlocking portion is formed at a predetermined portion of the support frame of the guide member, and the fixing portion is formed at a predetermined portion of the outer plate. A measurement hole into which a scale for measuring the interval between the portions can be inserted is formed in the outer plate.

[Operation] In addition to the same operation as the operation according to the first aspect, the following operation can be obtained.

The interlocking portion is formed at a predetermined portion of the support frame of the guide member, and the fixing portion is formed at a predetermined portion of the outer plate of the transport unit. Therefore, the interlocking portion and the fixing portion do not need to be configured by dedicated components, and can be configured at low cost.

Since a measuring hole into which a scale for measuring the interval between the two predetermined portions can be inserted is formed in the outer plate, a scale such as a straight ruler or a caliper is inserted into the measuring hole. The interval can be measured with a simple operation.

[Effect] Accordingly, the manufacturing cost can be reduced and the inspection as to whether or not both guide members can be set to a desired guide width can be performed more easily and accurately.
