Conventionally, various methods are known for measuring dimensions such as length and width of sheets, or squareness, but none of them can measure dimensions and squareness at the same time, and if the sheet is curled, errors may occur. However, there was a drawback that errors also occurred depending on the light transmittance of the sheet. As an example of a simple means for measuring dimensions and squareness, as shown in Fig. 1, reference planes 2 and 2' are provided on two sides of the table and bull 1 of the squareness measuring jig, and Line 3, which also indicates the upper limit of the allowable value,
3'..., line 4, 4'... which also indicates the lower limit
There is a method of drawing ..., pressing the sheet against the reference surface, and checking whether the other two sides are within the line indicating the tolerance value.

However, even with this method, the absolute values of dimensions and squareness are inaccurate due to visual judgment, errors due to individual differences and curling still remain, and there are other drawbacks such as not being suitable for operation in a dark room. I couldn't avoid it. The invention of the present application improves the above-mentioned drawbacks and makes it possible to simultaneously measure the dimensions and squareness of particularly photosensitive sheets using a simple device and operation. A guide guide surface that serves as a reference surface is erected at right angles on the measuring surface of the measuring table, and two sides are set perpendicular to each other, and a detector with two sensors inside is fixed at the right-angled corners. One detector is provided, and one detector of the same structure that can move along the guide guide surface is provided in each of the vertical and horizontal directions, for a total of three detectors.

It is assumed that the sheet 20 is pressed against the reference plane 0X10Y. Al, Cl, A2, B, indicate sensors whose centers are placed on the reference plane;
The sensor is located next to and centered on side 22. A

Holes 34 are made at required locations on the measurement surface, and notches 35 are provided on the guide surface at corresponding positions so that light passes from the light projecting section to the light receiving section. (See Figure 3a).
Note that there is no guide surface where sensors Bl and C2 are located.
Only a hole is made in the measurement surface T. In this embodiment, an infrared light emitting diode is used as the light projecting section 31 so that the sheet is not sensitive to visible light even if it is sensitive to visible light, and a solar cell sensitive to infrared light is used as the light receiving element.

As shown in Figure 3b, the sheet P is the spatial dynamic range of the sensor (hereinafter referred to as "sensing area").
If the area covered by the sheet P exceeds the center line as shown by JPl in the figure, the output will be positive, and outside the center line as shown by P2, the output will be negative. Set it so that the output is . That is, the maximum negative output is set when the sheet does not cover the sensing area at all, and the maximum positive output is set when the sheet covers the entire sensing area. Naturally, the sensor output and the sheet P from the center of the sensing area
There must be a proportional relationship with the distance to the end face position. For measurement, a measurement sheet P is placed within the reference planes 0X and 0Y and pressed against the reference plane.

When the sheet P covers the sensing area, the negative value of the output gradually becomes smaller, and when the sheet reaches the center of the sensing area, the output becomes zero. In Figure 2, Al, Cl,,
llll! , B2 are all zero, which means that the perfectly perpendicular sheet has been correctly positioned. However, even if it does not reach that point, the absolute values of the outputs to Al, Cl, A2 and are below the predetermined values. If so, positioning is assumed to have been completed and measurement is performed. Squareness is Al, Cl, A2 and B
It can be measured in 2.

As shown in FIG. 4, if one side of the sheet P is not parallel to the reference plane 32, A1 and C1 have different areas covered by the sheet P, so A1 and C1 have different outputs, and the difference is Therefore, the difference d in distance from the reference plane 32 between the position of one side of the sheet P at the sensor A1 and the position at the sensor C1 is measured. Now, let us assume that the inclination angle of the sheet P is 0 and the distance between the sensors Al and Cl is 1.

Although this mechanism is not shown in FIG.
They are provided at appropriate positions on both ends of the paper presser 43 on the paper holder 1. The paper presser is usually raised upwards as shown in the figure. When the sheet to be measured is placed on the measurement surface 51 and pressed against the reference guide surface 32 as described above, the sheet goes under the detector, blocks the infrared rays from the light projecting section 31, and reduces the output of the solar cell above. If the negative value becomes smaller and becomes smaller than the predetermined value, it is assumed that positioning has been performed.
The solenoid 46 operates to push up the rod 47 against the spring 45, and the paper presser 43 rotates via the swing table 44, thereby pressing the sheet P.
The measurement will be performed during this time. 8th
The figure shows the configuration of the movable detector 41 or 42.

In addition, a notch for light projection is provided in the corresponding position on the paper pusher 43.A diffuser plate 37 is provided above the light projection element so that the illuminance is uniform. There is a mounting plate 68 for the light-receiving element, and solar cells 36, 3', which are light-receiving elements corresponding to the light-emitting elements 31, 3', are attached to the mounting plate 68. Condenser lenses 38, 3' are also provided on the mounting plate.

Although it is possible to change the brightness of the light emitting diode depending on the transmittance of the sheet, it is more practical to change the amplifier gain. In order to perform this compensation automatically instead of manually switching a switch according to the paper quality of the sheet, another sensor is installed in the fixed detector 40 at a position that is always covered by the sheet, in addition to the sensors Al and A2. If this is done, the difference in sensor output is always due to the difference in sheet transmittance, so the amplifier gain can be changed based on the value of the difference.

(c) an optical sensor for detecting the edge of the sheet to be measured consisting of a light emitting/receiving section disposed on the measuring table; (c) calculating a deviation from the standard dimension and perpendicularity of the sheet to be measured based on the output from the optical sensor; A sheet dimension and squareness measuring device consisting of each element of an arithmetic circuit. 2. Optical sensors disposed on the extension part of the first guide and the extension part of the second guide are movable along the guide surfaces of the first guide and the second guide, respectively. A sheet size and squareness measuring device according to claim 1. 3. The sheet according to claim 1, characterized in that a pressing member is provided on the guide surface side of the first guide and the second guide to press the end surface of the sheet to be measured against the flat surface of the measuring table. Dimension and squareness measuring device. 4. The sheet dimensions according to claim 1, further comprising a display circuit that digitally displays the output from the arithmetic circuit or the absolute size of the sheet obtained by adding a predetermined reference value to the output. and squareness measuring devices.
