Description

DETAILED DESCRIPTION OF THE INVENTION (A) Field of Industrial Application The present invention relates to an electronic copying machine in which a document table reciprocates on the upper surface of a copying machine main body.

(b) Prior Art In an electronic copying machine in which the document table moves back and forth on the top surface of the copying machine main body, when the copying machine main body is transported, the document table slides on the top surface of the copying machine main body and its edges are There was a risk that the document would protrude and thereby damage the document table, which is made of a glass plate.

Therefore, to prevent the document table from moving during transport,
There is also a copying machine in which a locking member is attached to the main body of the copying machine, and the document table is locked by this locking member (for example, see Japanese Utility Model Application No. 57-65341).

(C) Problems to be Solved by the Invention In the conventional electronic copying machine described above, the original platen is locked so that it does not move to any of the main bodies, so it is difficult to release the original platen while it is locked. If you forget to start the copying operation, the document table, which is urged to move, will be prevented from moving by the locking member, and undesired stress will be applied to the drive system, which may cause damage to the drive system. It was hot.

Also, since two locking members were required,
The number of parts increased, material costs and man-hours increased, leading to an increase in costs.

(d) Means for Solving the Problems The present invention provides an electronic copying machine in which a document platen reciprocates on the top surface of the copying machine main body when in use. A handle attached to one side surface substantially perpendicular to the direction of movement of the table; a document table that first moves in the direction of the side surface upon the start of a copying operation; a handle attached to the other side surface opposite to the side surface; a locking member that is removably attached to the document table and protrudes from the top surface, which prevents movement of the document table in the direction of the other side, but allows movement of the document table in the direction of the other side; means for biasing the locking member in a direction to sink into the upper surface, and when the locking member protrudes from the upper surface, upon initiation of the copying operation;
The electronic copying machine is characterized in that, after the document table moves in the side direction, the locking member is recessed into the upper surface by the urging means.

(e) Effect In the present invention, a lock member is provided to prevent the document table from moving in the opposite direction to the side on which the handle is attached, so that the operator cannot operate the copying machine by grasping the handle. Even when carried around, the original platen will not slide off the top surface of the copying machine body.

(f) Embodiment The drawings all show one embodiment of the present invention, with FIG. 1 being a perspective view, FIGS. 2 and 3 being a front view showing different aspects, and FIG. 4 showing a locking member. FIG.

In these figures, reference numeral 1 denotes a main body of the copying machine, and a document table 2 that reciprocates in the horizontal direction is mounted on the upper surface of the main body of the copying machine. A handle 3 for carrying the copying machine main body 1 by hanging it is fixed to one side wall of the copying machine main body 1 perpendicular to the direction of movement of the document table 2. Further, a lock member 4 is attached to the other side wall opposite to the side wall on which the handle 3 is fixedly attached, so as to be slidable in the vertical direction. The upper end of this locking member 4 is slightly bent in the direction of the side wall on which the handle 3 is fixed, and the upper end of the locking member 4 is bent slightly toward the side wall on which the handle 3 is fixed.
It is constructed so that it can be engaged with recesses 6 and 7 cut into the top plate 5 of.

Further, the locking member 4 is engaged with the other end of a tension spring 8 whose one end is engaged inside the copying machine main body 1, and is constantly pulled in the retracting direction with respect to the top plate 5 of the copying machine main body 1. Forced. Reference numeral 9 denotes a transparent glass plate serving as the base of the document table 2. 10 is a prismatic cushion member, and 11 is a manual paper feed guide.

When transporting the copying machine, the locking member 4 is lifted against the tension spring 8, its bent portion is engaged with the recess 6 of the document table 2, and the handle 3 of the copying machine body 1 is Just hold it and carry it. At this time, the document table 2 is locked by the locking member 4, so that it does not slide down the top surface of the copying machine main body 1 (see FIG. 2). When the copying machine is to be operated, the document table 2 may be moved to the side opposite to the side where the locking member 4 is provided. Then, the bent portion of the lock member 4 separates from the recess 6 of the document table 2, and the lock member 4 is recessed into the upper surface of the copying machine main body 1 by the tension spring 8. Therefore, the document table 2 can reciprocate on the upper surface of the copying machine main body 1 (see FIGS. 3 and 4).

Note that if the initial movement direction of the document table 2 is set to be opposite to the side where the locking member 4 is provided, when the operator operates the copying machine, the locking member 4 will be locked. without canceling
Copy operations can begin immediately. That is,
When a copying operation is started after the copying machine main body 1 is placed on a horizontal table, the original platen 2 first moves in the opposite direction (unlocking direction) to the locking member 4, so as described above, The lock will be automatically released,
Even when the document table 2 returns, the lock member 4 no longer prevents the document table 2 from moving back.

(G) Effects of the Invention In the present invention, when the lock member protrudes from the top surface of the copying machine main body, movement of the document table in the opposite direction to the side where the handle is provided is prevented, so the handle Even if you carry the copying machine by holding it, the document table will not slide off the top surface of the copying machine body.

Furthermore, since one locking member is sufficient, material costs and assembly man-hours can be reduced.

Furthermore, if the locking member protrudes from the top surface of the copying machine main body, after the document table moves in the opposite direction from the side where the locking member is provided upon the start of the copying operation, the locking member is pushed by the biasing means. Since it is recessed into the upper surface, the lock is automatically released at the same time as the copying operation starts, and even if you forget to release the lock, no undesired stress will be applied to the drive system.
