Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention 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.

[0002]

2. Description of the Related Art In an electronic copying machine in which a document table reciprocates on the upper surface of a copying machine body, the document table slides on the upper surface of the copying machine body when the copying machine body is conveyed, and its edge projects. As a result, there is a risk that the document table formed of the glass plate may be damaged.

In order to prevent the original table from moving during transportation, there is a locking member attached to the main body of the copying machine, and the original table is locked by this locking member (for example, Japanese Utility Model Laid-Open No. 57-65341). reference).

[0004]

In the above-mentioned conventional electronic copying machine, since the document table is locked so as not to move in any direction, it is forgotten to release it while the document table is locked. Then, when the copying operation is started, there is a possibility that the original table, which is urged to move, is prevented from moving by the lock member, undesired stress is applied to the drive system, and the drive system is damaged. .

SUMMARY OF THE INVENTION According to the present invention, in an electronic copying machine in which a document table reciprocates on the upper surface of the copying machine body in use, the document table of the copying machine body is moved to convey the copying machine body. A handle attached to one side surface substantially orthogonal to the direction, a recess formed in the document table, and the other side surface opposite to the side surface so as to be retractable with respect to the upper surface, and So that its upper end can engage the recess,
The lock member bent in the one side surface direction, the leg member provided on the other side surface and protruding in the reciprocating direction of the document table from the lock member, and the lock member retracted into the upper surface. And a means for urging in a direction, and when the lock member projects from the upper surface and is engaged with the recess, it prevents movement of the document table in the other side surface direction. The lock member is allowed to move in one side surface direction, and the lock member is disengaged from the recess by the movement of the document table in the one side surface direction so as to be depressed in the upper surface. It is a characteristic electronic copying machine.

[0007]

In the present invention, since the lock member is provided to prevent the document table from moving in the direction opposite to the side on which the grip is mounted, the operator holds the grip and carries the copying machine. However, the platen does not slide down on the top of the copier body.

1 is a perspective view, FIG. 2 and FIG. 3 are front views showing different modes, and FIG. 4 is an enlarged cross-sectional view showing a lock member. It is a figure.

In these figures, (1) is a main body of a copying machine, and an original table (2) which reciprocates in the horizontal direction is mounted on the upper surface thereof. A handle (3) for suspending and carrying the copying machine body (1) is fixedly provided on one side wall of the copying machine body (1) orthogonal to the moving direction of the document table (2). There is. A lock member (4) is mounted on the side wall opposite to the side wall on which the handle (3) is fixedly mounted so as to be vertically slidable. This locking member (4)
At the upper end of the recess, a slight bending is formed in the direction of the side wall on which the handle (3) is fixed, and a recess is formed in the original plate (2) and the top plate (5) of the copying machine body (1). Office (6)
It is configured so that it can be engaged with (7).

The lock member (4) has a tension spring (8) whose one end is engaged with the inside of the copying machine body (1).
Is engaged with the other end of the copying machine main body (1) and is always urged in the retracted direction with respect to the upper plate (5) of the copying machine body (1). Reference numeral (9) is a transparent glass plate which is a base of the original table (2). (10)
Is a prismatic cushion member, and (11) is a manual paper feed guide.

When carrying the copying machine, the lock member (4) is lifted against the tension spring (8), and the bent portion and the recess (6) of the document table (2) are engaged. Then, the handle (3) of the copying machine body (1) may be gripped and carried. At this time, the document table (2) is locked by the lock member (4) and does not slide down on the upper surface of the copying machine body (1) (see FIG. 2).

When operating the copying machine, the document table (2) may be moved to the side opposite to the side provided with the lock member (4). Then, the bent portion of the lock member (4) is released from the recess (6) of the document table (2), and the lock member (4) is immersed in the upper surface of the copying machine main body (1) by the tension spring (8). To do. Therefore, the document table (2) can reciprocate on the upper surface of the copying machine body (1) (see FIGS. 3 and 4).

The original moving direction of the platen (2) is
If the setting is made so that the direction opposite to the side in which the lock member (4) is provided, when the operator operates the copying machine, the copying operation is immediately performed without unlocking the lock member (4). Can start. That is, when the copying operation is started after the copying machine body (1) is placed on a horizontal table, the document table (2) first moves in the direction opposite to the lock member (4) (unlocking direction). , As above,
Even if the lock is automatically released and the platen (2) returns, the lock member (4) no longer prevents the platen (2) from returning.

[0014]

According to the present invention, since the leg member protruding from the lock member in the reciprocating direction of the document table is provided, the operator grasps the handle for carrying the copying machine, and the installation surface is used as an axis. By rotating the lock member 90 ° from 90 °, it is possible to prevent damage or deformation of the lock member and damage or twisting of the document table due to abrupt release of the lock member that engages with the recess of the document table. In addition, it is possible to prevent an indirect adverse effect on the document table due to the deformation of the lock member. This effect also appears when the operator unloads the copying machine while carrying it, such as when the operator arrives at the destination carrying the copying machine.

Therefore, the copying machine is not damaged not only when carrying it but also when carrying it.

Further, if the original moving direction of the document table is set to the opposite direction to the side provided with the lock member as in the above-mentioned embodiment, the lock member is started at the same time when the copying operation is started. The lock with the platen is automatically released, and even if the lock release is forgotten, undesired stress is not applied to the drive system.
