Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a position adjustment device that can easily and easily adjust the position of a component to be adjusted such as an image sensor.

FIG. 1 is a simplified explanatory diagram showing a conventional alignment adjustment device installed in an image sensor used to read characters, etc. on a document on the sending side of a facsimile machine. When the engaging end 6 of the adjustment lever 5, which is supported around the fulcrum 4 as a rotation center, fits into the groove 3 provided in the attached fixture 2, and the adjustment lever 5
0 Both ends have fine adjustment screws 8 screwed onto fixing pieces 7a and 7b.
The tips of a and 8b are respectively locked.

In this configuration, when one fine adjustment screw 8a is turned in the tightening direction and the other fine adjustment screw 8b is turned in the longitudinal direction, the adjustment lever 5 rotates about the fulcrum 4 and engages as shown in FIG. The part to be adjusted 1 is moved along with the fixture 2 by the moving distance t of the tip of the end portion 6.
can be moved in the direction of arrow A, and conversely, one fine adjustment screw 8a can be moved in the direction indicated by the long line, and the other fine adjustment screw 8b can be moved in the direction indicated by the long line.
By turning in the tightening direction, the part to be adjusted 1 can be moved in the direction of arrow B, so the part to be adjusted 1 can be moved in a desired direction to perform alignment adjustment.

However, this method has the disadvantage that the positioning adjustment must be made by alternately turning the two fine adjustment screws as described above, making the work cumbersome and inefficient.

FIG. 3 is a simplified explanatory diagram showing another conventional example, in which the part to be adjusted 1
An engagement end 10 of an adjustment lever 9 supported around a fulcrum 4 as a rotation center is slidably fitted into a groove 3 provided in a fixture 2 to which the adjustment lever 9 is attached, and one end of the adjustment lever 9 has a fine adjustment mechanism. screw 1
The screw portion 12 of 1 is screwed together, and the base of the fine adjustment screw 11 is fitted into the fixing piece 13 so as to rotate freely, and the retaining ring 14 is inserted.
Fixed by

Therefore, when the fine adjustment screw 11 is turned in the direction indicated by the long line, the adjustment lever 9 rotates in one direction about the fulcrum 4 as shown in FIG. The part to be adjusted 1 can be moved in the direction of the arrow A together with the tool 2, and the part to be adjusted 1 can be moved in the direction of the arrow B by turning the fine adjustment screw 11 in the tightening direction.

However, this method has disadvantages in that the fine adjustment screw is inclined with respect to the fixed piece during position adjustment, which may cause the retaining ring to come off or the screw thread of the fine adjustment screw to break.

The purpose of the present invention is to provide a positioning adjustment device that can extremely easily adjust the positioning of parts to be adjusted and that does not cause the screw threads of fine adjustment screws to break.
Two fulcrums in which two adjustment levers of different lengths, each having a projecting piece protruding at one end at a nearly right angle and the other end engaged with the part to be adjusted, are positioned at equal distances from the part to be adjusted. The base of the fine adjustment screw is fixed to the protrusion of one adjustment lever so as to rotate freely, and the threaded part of the fine adjustment screw is screwed to the protrusion of the other adjustment lever. When the fine adjustment screw is rotated, the protrusion threaded onto the threaded portion moves, and this movement is converted into rotation of both adjustment levers to move the adjusted component.

FIG. 5 is a simplified explanatory diagram showing an embodiment of the present invention that allows positioning adjustment of one or more image sensors connected. There are two pins 1 on the fixture 2.
5a and 15b are provided with an interval between them.

16a and 16b are adjustment levers of different lengths, and supports A17a and 17 are located at the same distance from the part to be adjusted 1.
The fulcrums 17a and 1
The spacing between pins 7b is the same as that of the pins 15a and 15b.

A projecting piece 18a is provided at one end of both the adjustment levers 16a and 16b.
, 18b are provided substantially perpendicular to the direction in which they face each other, and a recess 19a corresponding to the pins 15a, 15b of the fixture 2 is provided at the other end.

19b is provided and engages with the pins 15a and 1sb.

Reference numeral 20 denotes a fine adjustment screw, the base of which is fitted into the protrusion 18a of one of the adjustment levers 16a so as to rotate freely, and a retaining ring 21.
Fixed by

The threaded portion 22 of the fine adjustment screw 20 is screwed into the projection 18b of the other adjustment lever 16b.

When the fine adjustment screw 20 is rotated, the protruding piece 18b is attached to the threaded portion 2.
2, it is configured to move parallel to the protruding piece 18a.

Next, to describe the operation of the above configuration, the part to be adjusted 1 is indicated by the arrow A.
When moving the fine adjustment screw 20 in the direction indicated by the long line, the protrusion 18 of the adjustment lever 16b will move along with the rotation.
b moves toward the tip of the fine adjustment screw 20, and then the adjustment levers 16a, 1 move in response to the movement of the protrusion 18b.
As shown in FIG. 6, pins 15a and 15' rotate in one direction about their respective fulcrums 17a and 17b, and are engaged with recesses 19a and 19b of adjustment levers 16a and 16b as they rotate. b are each pushed in the direction of arrow A,
Thereby, the part to be adjusted 1 is moved into the recess 1 together with the fixture 2.
9a and 19b can be moved in the direction of arrow A by a moving distance t.

When moving the part to be adjusted 1 in the direction of arrow B, turn the fine adjustment screw 20 in the tightening direction, and the adjustment lever 16
As shown in FIG. 7, the protruding piece 18b of b moves toward the base of the fine adjustment screw 20, and the adjustment lever 16a.

16b rotates in the opposite direction to that described above, and the part to be adjusted 1 can be moved in the direction of arrow B by a moving distance t of the recesses 19a and 19b.

Therefore, the fine adjustment screw 20 is turned to move the part to be adjusted 1 in a desired direction to perform alignment adjustment.

In addition, in the above configuration, the pin 15a is attached to the fixture 2.

15b, and recesses 19a in the adjustment levers 16a, 16b that engage with the pins 15a, 15b.

19b is provided, but the pins 15a, 15b and the recess 19
a, 19b may be provided in the opposite manner to the above, and the pins 15a, 15b and the recess 19a.

Other engaging means may be used as long as they function similarly to 19b.

According to the present invention having the above configuration, the fine adjustment screw is attached to the projecting pieces of the adjustment lever of different lengths, which are rotatably supported on a support located at an equal distance from the part to be adjusted. When the projecting piece of one adjustment lever is moved by the rotation of the adjustment lever, the movement is converted into rotation of both adjustment levers, and the adjusted part engaged with the other end of the adjustment lever is moved. The positioning adjustment of the parts to be adjusted can be performed extremely easily, and the efficiency of the adjustment work can be improved.

In addition, the fine adjustment screw is attached at right angles to the protrusions of both adjustment levers, and the movement of one protrusion by rotation of the fine adjustment screw results in parallel movement to the other protrusion, so the fine adjustment screw It can always maintain a right-angled posture with respect to both protrusions, thus eliminating defects such as the retaining ring coming off and screw threads breaking.It is useful not only for image sensors but also for adjusting parts that require alignment adjustment. It has a wide range of uses as a device.
