Abstract

PURPOSE:To make a driving motor unnecessary, by providing an elastic member stretched on other link engaged with a link which executes a reciprocating motion in a pair of solenoids, and rotating a rotary base. CONSTITUTION:A rotary base 3 on which an aperture card has been placed rotates on a scan base 1 by making a hollow rotary shaft as a shaft. A detaining long hole 11 of one end of the second link 10 which has a supporting point pin 9 as a supporting point is fitted to a detaining pin 8 of the first link 7, and between the other end of the second link 10 and a supporting pin 12, a spring 13 is stretch-provided. When a solenoid 5 attracts the first link 7, the second link 10 is rocked against a spring 13, and when the spring 13 has crossed over the line for connecting the supporting point pin 9 and the supporting pin 12, the rotary base 3 starts to rotate, and rotates by 90 degrees. When energizing of the solenoid 5 is released and a solenoid 6 is energized, the rotary base is returned to its original position. Stoppers 14, 15 exactly position the rotary base, and its rotation can be executed exactly by a simple mechanism.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to loading an aperture card by 90 degrees to perform longitudinal copying on an aperture card scanning device.

As shown in FIGS. 1 and 2, the aperture card rotating device in a conventional micro copying machine is placed on a scanning table 01 and the scanning table Ol, and a turntable drive motor 03 rotates a wire 04. It consists of a turntable 02 physically connected to a rotating drum 05 which is rotationally driven through a wire 04, and the turntable 02 is rotated by a turntable driving gear 03 through a wire 04. As a result, the manufacturing cost of the device is high, and the reliability of the reliable rotation of the turntable 02 is poor.

The present invention has been made to deal with such drumheads, and its purpose is to rotate the turntable using a solenoid and a trouble mechanism, thereby reducing device manufacturing costs and improving the reliability of the device. An object of the present invention is to provide an aperture card rotation device for a microcopying machine that achieves improvements in the above.

An embodiment of the present invention shown in FIGS. 3 to 6 will be described below.

A hollow rotating shaft 2 is rotatably inserted into a predetermined opening of the scanning table 1, and a hollow rotating shaft 2 is inserted into a predetermined opening of a turntable 3 which is rotatably and slidably placed on the scanning table 1. The upper end of 2 is pivotally connected.

Furthermore, a pair of opposing support pieces 4- are fixed at a predetermined location on the turntable 3 away from the hollow rotating shaft 2, and a pair of solenoids 5.6 are attached to the support pieces 4. is supported at a predetermined height.

Furthermore, a first link 7 (side member) that is movable back and forth within the solenoid 5.6 is disposed across the solenoid 5.6, and is connected to a fulcrum pin 9 (also known as a fulcrum pin 9) protruding from the turntable 3. The fulcrum pin 9 is rotatably supported so that the straight line connecting the fulcrum pin 9 and the axis of the hollow rotating shaft 2 is approximately parallel to the pair of sides of the turntable 3. The locking elongated hole of the second link 10 that has been raised is engaged with a locking pin that is protruded at an intermediate position in the longitudinal direction of the first link 7,
A support hinge 12 (the support pin 12 is connected to the turntable 3
When the is in the normal position before rotating 900 times, the support pin 1
A tension coil spring 1 is tensioned between the fulcrum pin 9 and the fulcrum pin 9.

Furthermore, the normal position of the turntable 3 and 90
° At the same rotation position, a stopper 14.15 for positioning the table 3 is protruded from the scanning table 1, and a stopper pin +6.17 for determining the swing stroke of the second link 10 is placed at a predetermined position on the turntable 3. It is installed protrudingly.

The embodiment shown in FIGS. 3 to 6 is constructed as described above, and the aperture card transported by a transport device (not shown) rotates its microfilm portion in a hollow manner, and the upper end of the shaft 2 is opened. When the solenoid 5 is energized in the state shown in FIG. 1, the first link 7 is Attracted by the solenoid 5, the second link 10 is swung against the coil spring 13, and the spring of the second link 10
1 When the connecting end crosses the straight line connecting the fulcrum pin 9 and the support pin 12, the turntable 3 force i coil spring 1
The turntable 3 starts to rotate due to the tensile force of 3, and after passing through the state shown in FIG. 5, the turntable 3 is positioned and stopped by the stopper 15, as shown in FIG.

At that time, the second link 10 is stopped from swinging at the stopper bin 1f position.

After blowing and completing the specified copying, if the solenoid 6 is energized with the solenoid 5 deenergized, the first link 7 is attracted and the second link 10 resists the coil spring 13. When the spring connecting end of the second link 10 crosses the straight line connecting the fulcrum pin 9 and the support pin 12 in the state shown in FIG. Rotation starts due to the tensile force, and after passing through the state shown in FIG. 15, the turntable 3 is positioned and stopped by the stopper 14 as shown in FIG. 3. At that time, second link 10? Well, trapper pin 16
Rocking is stopped at the position.

As described above, in the embodiments shown in FIGS. 3 to 6, a pair of solenoids 5.6 are provided at predetermined positions of the main turntable 3, and the first and second links are engaged with each other. 7.10, a fill spring 13 is stretched between one end of the second link 10 and a predetermined position of the scanning table 1, and the turntable 3 is rotated by 90° by reciprocating the first link. Since it is made to rotate, it can be rotated reliably using a simple mechanism.

In addition, stoppers 14 and 15 are installed,
If the turntable 3 can be accurately positioned when reciprocating by 90°, the turntable 3 is reliably held at the stopper 14 or 15 position by the coil spring 13. ~Furthermore, the second link 10 is provided with a locking elongated hole 11 so as to be engaged with the locking pin 8 of the first link. (7) Rocking is performed smoothly.

Furthermore, since the coil spring 13 is stretched at a predetermined height on the large table 3 as shown in FIG. 4, it does not become a hindrance when placing the aperture card on the turntable 3.

In the above embodiment, the pair of solenoids 5 and 6 were fixedly arranged directly on the turntable 3, but it is also possible to arrange them directly on the scanning table 1 (i.e., with the solenoid 5 at the stopper 14 position, Even if the solenoid 6 is protruded from the stopper 5 position) and the first link 7 is moved back and forth, substantially the same effect can be obtained. However, in that case, it is necessary to provide a member on the turntable 3 for supporting and guiding the first link 7.

As is clear from the description of each of the above embodiments, the present invention has the following features:
In an apparatus for rotating an aperture card of a microcopying machine, first and second links in engagement with each other are disposed at a predetermined position on the turntable apart from the rotation axis of the turntable, and A solenoid for reciprocating the link is disposed at a predetermined position, an elastic member is stretched between one end of the second link and a predetermined position of the scanning table, and the first link is reciprocated. As a result, the turntable is rotated 900 times back and forth, and reliable rotation can be achieved with a simple mechanism that does not require a monitor or the like, and the manufacturing cost of the device is low.
