Abstract

PURPOSE:To make exhaustion smooth by intermittently driving an upper and a lower guide plate round the lower supporting shaft using a geneva wheel when a recording sheet is exhausted to a tray, and thereby moving exhaust roller one after another so as to be in correspondence to a plurality of trays. CONSTITUTION:When a recording sheet inserted from a feed hole 18 comes in contact with a sensor 17, a motor drives an exhaust roller 7, and the recording sheet is nipped by a pinch roller 8 to exhaust to a specified tray 15. When exhaustion is finished, another motor 12 rotates a geneva wheel 10 through a geneva cam 1, and the above-mentioned exhaust roller 7 is moved to the position possible to exhaust to the next stage tray to stop when it comes in contact with a micro-switch 14. At this time, a case 1 bears an upper 2 and a lower 3 guide plate through shafts 4A, 5A, while a shaft 7A of exhaust roller 7 is borne by a lower side plate 5 which supports the lower guide plate 2. The Geneva wheel 10 is supported concentrically with said shaft 5A of lower guide plate 3.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a T-combined sound, and more particularly to a T-combined sound which is convenient and suitable for a post-processing device of a small-sized copying machine.

[Conventional technology]

Traditionally, T-combiners, which have been used as post-processing devices for copying machines, printers, etc., have multiple tray bins arranged and fixed in a vertically spaced stacked state. When the recording materials are received from the feeding port of the apparatus, they are sequentially and selectively transported to the trays by the transport device, and then discharged onto the trays by the discharge means.

However, in recent years, with the spread of copying, moxibustion, and printers, there is a high demand for small and medium-sized devices, and there is a strong demand for the development of a compact, easy-to-handle, claw-side collating device suitable for this type of copying machine. It became so.

(Problems to be Solved by the Invention) In view of the above-mentioned problems, it is an object of the present invention to be suitable for post-processing devices such as small and medium-sized copying machines, which are simple and easy to use for general users, and which can be obtained at low cost. Our goal is to provide a M made of T-gold.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a system in which a recording material guided from a feeding port between an upper guide member and a lower guide member is moved between a discharge roller and a pinch roller. In a T-coupling device that can be held between the trays and delivered to one of the trays arranged above and below with a predetermined interval, the upper support shaft and the lower support are arranged above and below the feeding port. a lower guide member rotatably supported by the lower support shaft and having a discharge roller pivotally supported on the tray entrance side; and a lower guide member rotatably supported by the upper support shaft and rotatably supported on the tray entrance side. An upper guide member connected as a link via the connecting shaft and the shaft of the ejecting roller by a connecting portion 4 that pivotally supports the pinch roller, a driving means for the ejecting roller, and a lower support shaft are coaxially fixed, A Geneva wheel that rotates and forces the lower guide member together with the lower guide member via the lower support IM, a Geneva cam that is coupled to the Geneva wheel and capable of intermittently rotating the Geneva wheel, and a drive means for the Geneva wheel. When the recording material is inserted from the feed port, the ejection roller is driven, and when the recording material is ejected to the tray, the Geneva cam intermittently drives the upper guide member and the lower guide member around the lower support shaft via the Geneva wheel. It is characterized by being made to do.

[Effect]

In the T-combining device of the present invention, the upper guide member and the lower guide member are connected to the link of the four-bar rotation mechanism by the connecting member on the tray entrance side, and the fan-shaped Geneva wheel is fixed coaxially with the horizontal rotating glaze of the lower guide member. The horizontal plane above due to the rotation by the Geneva cam! The Geneva wheel is rotated around the JJJ axis, and the Geneva wheel is configured to be rotated intermittently by the Geneva cam. Now, when the recording material is inserted through the feeding port, this is detected and the feeding motor drives the ejection roller, and when the recording material is ejected to the tray, the feeding motor stops. The guide motor is then driven, which rotates the Geneva cam and rotates the Geneva wheel by an amount corresponding to the spacing between the trays, and then the motor is stopped, and the above operation is repeated for each tray.

It goes without saying that it is possible to transmit the light in exactly the same direction, for example, in the horizontal direction.

The operation of the T-gold device configured as described above will be explained with reference to FIGS. 1 to 5. When a recording material is inserted from the feed port 18, it touches the actuating piece 17A of the sensor 17, and this By tilting the , the recording material is detected, and the drive motor 23 drives the discharge roller 7 to pinch the recording material between the pinch roller 8 and transfer it to the uppermost tray 15, for example.

Once the discharge is finished, next time! By 5I2rBJ motor 12,
The Geneva wheel 10 is rotated, for example, in the counterclockwise direction in FIG.
When the ejection roller 7 moves to a position where it can be ejected to the tray 5, its drive is stopped by the microswitch 14, and the recording material to be fed next can be ejected to the tray again in the same manner.

Although not described in detail, when the ejection roller 7 is at the top tray position and when it is at the bottom tray position,
Needless to say, the device is configured so that these can be detected.

In addition, as shown in Fig. 3, the upper part of the outer case 1 is provided with a 'fi 25 that can be opened and closed, and by opening this lid 25, it is possible to remove the recording material in the event of a jam or to inspect it. It can be implemented.

Since it is possible to intermittently rotate around the tray by a rotation angle corresponding to the spacing of the trays, the connection between the two parts and the lower support shaft, the connection part of the connection member with the upper guide member, and the ejection roller shaft. It is now possible to appropriately set the relative position 'it', thereby making it possible to regulate the direction of the common contact surface between the ejection roller and the pinch roller in a substantially constant direction, thereby making it possible to eject the recording material to the tray. Not only can the image be printed in one color smoothly, but the entire device can be configured compactly, making it possible to develop a T-gold device that is especially suitable for attaching to small and medium-sized copying machines. It has become possible.
