A device for fixing and holding a document or a recording material in a flat shape such as a recording paper table for fixing and holding a recording material in a flat shape in a flat receiver for receiving a document or an image output device for an automatic typesetting system (Hereinafter, referred to as a document or recording material pressing device).

2. Description of the Related Art A document or recording material pressing device used as a document table of a conventional flat-type transmitter or a recording paper table of a flat-type receiver is the fourth one.
As shown in the figure, a support base 1 on which a document or recording material is placed,
The press cover 3 is provided with a press plate glass 2 for pressing an original or a recording material placed on the support 1. The press cover 3 is rotatable with respect to the support 1 about a support shaft 4. It is provided with a handle 5 for opening and closing it, a lock mechanism 6 for fixing the pressing cover 3 on the support base 1, and the like. 5 (a) and 5 (b) show the handle 5 and the lock mechanism 6 in an enlarged manner.
It is simply fixed to. The lock mechanism 6 includes a lock pin 7 provided on the support base 1 and a lock arm 9 provided on the presser cover 3 so as to be rotatable about a fulcrum shaft 8 and provided with a lock groove 9a that engages with the lock pin 7. , The camshaft 10 for rotating the lock arm 9, and the lock arm 9
The leaf spring 11 that presses the camshaft 10 against the camshaft 10,
It has a lock release knob 12 attached to one end of 10.

In this document or recording material pressing device, for example, in order to set a document, the operator holds the handle 5 with one hand and the unlocking knob 12 at the position shown by the solid line in FIG. 5 (b) with the other hand. Is rotated in the direction of arrow A. By this rotation, the cam shaft 10 rotates to rotate the lock arm 9 in the direction of the arrow B, disengage it from the lock pin 7, and the presser cover 3 can be opened. By pushing up the handle 5 in this state, the presser cover 3 is opened. Then, after the document is mounted on the support base 1, the handle 5 is simply held and the presser cover 3 is simply pushed down so that the lock pin 7 automatically engages with the lock arm 9 and the presser cover 3 is placed on the support base 1. Holds in close contact.

Further, as another conventional example, as shown in FIG. 6, a support base 1 and a holding cover 3 having a holding plate glass 2 rotatably held around a support shaft 4 are provided. There is a presser cover 3 provided with a rotatable handle 14. As shown in FIG. 7, the handle 14 is attached to a rotatable fulcrum shaft 15 on the pressing cover 3, and the fulcrum shaft 15 has
A lock arm 16 having a lock groove 16a is fixed. A lock pin 17 that engages with the lock groove 16a is fixed to the support base 1. In this conventional example, as shown by the chain line in FIG. 7, the lock arm 16 is disengaged from the lock pin 17 by pushing the handle 14 upward, so that the handle cover 3 can be opened by lifting the handle 14 in this state. Further, in order to close the presser cover 3, the presser cover 3 is lowered while the handle 14 is tilted with respect to the presser cover 3 so that the lock arm 16 does not come into contact with the lock pin 17. Finally, by returning the handle 14 to the original position by the operator's hand, the lock pin 17 is engaged with the lock groove 16a of the lock arm 16.

Problems to be Solved by the Invention However, all such conventional devices have problems. That is, in the apparatus shown in FIG. 4 and FIG. 5, both hands are required to open the presser cover 3, so the workability is poor. Usually, since the operator often holds the next original in one hand, it is preferable that the operator can operate it with one hand. However, if the operator tries to operate the apparatus shown in FIGS. 4 and 5 with one hand, It requires a difficult operation of turning the lock release knob 12 in the direction of arrow A, replacing it with the immediate handle 5 and lifting the presser cover 3.

In the device shown in FIGS. 6 and 7, the handle 14 can be opened and closed by operating only the handle 14, so that the handle can be operated with one hand, but since the handle moves with respect to the presser cover, the opening and closing operation of the presser cover by the handle becomes unstable, Further, there is a problem such as wear of parts that occurs when the lock arm engages with the lock pin.

As described above, in the conventional apparatus, since the operator opens and closes the presser cover in a human sense, there is a problem in that the operator uses extra force and the psychological anxiety increases.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a document or recording material pressing device including a pressing cover that can be easily opened and closed with one hand.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention uses a fixed handle of a presser cover, and arranges a rotatable lock release roller at the center of the handle. The lock arm is connected to the lock arm that engages with the lock pin, and the lock arm is rotated by the rotation of the lock release roller.

With the above-described configuration, the present invention allows the operator to hold the lock release roller at the center of the handle with one hand and rotate the lock release roller to rotate the lock arm to perform the lock release. By lifting the lock release roller, the presser cover can be opened. At this time, since the handle is a fixed type, the pressing cover can be stably opened and closed.

Example Hereinafter, an example shown in the drawings will be described. 1 and 2 are schematic perspective views showing a document or recording material pressing apparatus according to an embodiment in which the present invention is applied to a document table for a newspaper fax machine, and FIG. 1 shows a state in which a pressing cover is closed. Figure 2 shows the condition that the presser cover is opened. In FIG. 1 and FIG.
21 is a support table on which the document 20 to be transmitted is placed, and 22 is this support table
21 is a presser cover rotatably provided, 23 is a presser plate glass provided on the presser cover 22, and 24 is a presser cover 22.
Reference numeral 25 denotes a damper for urging the lever in the opening direction, and a handle fixed to the tip of the presser cover 22. Near the center of this handle 25,
The lock release roller 26 is rotatably held.

FIG. 3 is a schematic view showing the front end portion of the presser cover 22 in a sectional view, 27 is a lock pin fixed to a support base (not shown), and 28 is a fulcrum rotatably held by the presser cover 22. Shafts, 29 are fixed to the fulcrum shaft 28, a lock arm having a lock groove 29a that engages with the lock pin 27, 30 is a leaf spring that urges the lock arm 29 in the direction of pressing the lock pin 27, and 31 is A connecting mechanism that is connected to the lock release roller 26 and the lock arm 29 and converts the rotation of the lock release roller 26 into the rotation of the lock arm 29.

Next, regarding the document or recording material pressing device having the above configuration,
The operation will be described below.

When the presser cover 22 is closed on the support base 21, the lock arm 29 is locked by the leaf spring 30 as shown in FIG.
It is pressed against 27 and locked. When opening the presser cover 22 to remove or set documents,
The operator holds the lock release roller 26 of the handle 25 with one hand and rotates it in the direction of arrow D in FIG. As a result,
Since the lock arm 29 pivots in the direction of arrow E and disengages from the lock pin 27, the operator can open the presser cover 22 by holding and lifting the lock release roller 26. At this time, since the handle 25 is a fixed type, the operation of lifting the handle 25 by holding the lock release roller 26 is stable. Next, mount the document 20 on the support 21 and press the cover.
When closing the cover 22, the handle 25 is simply held and the presser cover 22 is simply pushed down. At this time, since the unlocking roller 26 is released, the lock arm 29 has already returned to the position shown by the solid line in FIG. 3 by the leaf spring 30, and the lower end portion of the lock arm 29 is moved downward as the presser cover 22 descends. The lock pin 27 comes into contact with the lock pin 27 and is rotated in the direction of arrow E, so that the lock pin 27 automatically engages with the lock groove 29a. Thus, when the lock pin 27 lowers the presser cover 22 to the lock groove 29a, the lock pin and the lock arm can be smoothly meshed with each other.

EFFECTS OF THE INVENTION As is apparent from the above description, according to the present invention, the handle of the presser cover is fixed, and the rotatable lock release roller is arranged at the center of the handle.
By connecting to the lock arm that engages with the lock pin and configuring the lock arm to rotate with the rotation of the lock release lock, the operator holds the lock release roller at the center of the handle with one hand and By rotating the lock arm, the lock arm can be rotated to release the lock, and by lifting the lock release roller as it is, the presser cover can be opened, and by holding the handle, you can push down the presser cover. Thus, the pressing cover can be smoothly closed, and the opening / closing operation of the pressing cover can be easily performed with one hand.
