Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a guide table device for setting articles such as forms at desired feeding positions.

For example, in printers, readers, etc., guide table devices are used to set documents and the like at desired feeding positions.

Therefore, in conventional guide table devices of this type, a means that uses frictional force or a means that uses claws is adopted as a means for fixing and holding the movable table on which forms are placed, but the former does not generate frictional force. Since the holding force is small compared to the force used to hold the movable table, it is difficult to fix and release the movable table, and the latter has the disadvantage that fine positioning cannot be performed because claws are used.

The present invention aims to solve these drawbacks, and is characterized in that a magnet is used to fix and release the movable table.

The following will be explained based on the drawings. Fig. 1 is a plan view showing an embodiment of the present invention, and Fig. 2 is a partially cutaway side view thereof. This is a fixing plate made of a magnetic material to hide the redundant structure of the insertion opening 1 and to fix and hold a movable table to be described later.On both sides of this fixing plate 2 are side plates 3 for regulating the width of the insertion opening 1. , 4 are formed in an upright manner.

Reference numeral 5 denotes a movable table on which the above-mentioned forms and the like are placed and set at a desired feeding position in the insertion slot 1, and a reference surface 6 is formed upright on one side thereof. This movable table 5 has two legs 7 provided on its lower surface,
8 is slidably fitted onto two parallel guide shafts 9 and 10, and is supported at a position above the fixed plate 2, as shown in FIG. It is possible to move to the position shown by the two-dot chain line in a direction perpendicular to the direction of insertion. A support piece 11 is also provided on the lower surface of the movable table 5, and the other end of a lever 13 having a permanent magnet 12 attached to one end is rotatably attached to the support piece 11 via a pin 14. ing.

In addition, when the movable table 5 moves in the direction of arrow A, the fixed plate 2 has legs 7 and 8 and a support piece 1.
A long hole is provided for the passage of 1.

A lock bar 15 is located at one end of the movable table 5, and is connected to one end of the lever 13 via an arm 16. This lock bar 15 is used to fix and release the movable table 5. When the lock bar 15 is pushed down by hand, the lever 13 rotates about the pin 14,
As a result, the permanent magnet 12 adhering to the lower surface of the fixed plate 2 separates from the fixed plate 2, allowing the movable table 5 to move freely, and when the lock bar 15 is released, it is returned to its original position by a spring (not shown). As a result, the permanent magnet 12 is attracted to the lower surface of the fixed plate 2, and the movable table 5 is fixedly held.

The size and attraction force of the permanent magnet 12 are set so that the movable table 5 can be fixedly held on the fixed plate 2 with sufficient force.

17 is a receiving plate provided in the feeding path at the back of the insertion slot 1; 18 and 19 are feed rollers for feeding forms, etc.; 20 and 21 are feed rollers 18,
19 is a pressure roller for pressing a form or the like.

Next, the operation of the guide table device having the above-described configuration will be explained.

First, a form or the like is inserted through the insertion slot 1 and placed on the movable table 5, and one side thereof is firmly abutted against the reference surface 6 provided on the movable table 5. After releasing the fixation of the movable table 5 by pushing down the lock bar 15 with your hand, move the movable table 5 to a desired position and then release your hand from the lock bar 15. is fixed to the fixing plate 2 again,
As a result, the forms and the like on the movable table 5 are set at the desired feeding position.

In addition, although the permanent magnet 12 is used in the above-mentioned embodiment, it is not limited to this, and it is also possible to construct it using an electromagnet and a switch, for example.

As explained above, since the present invention utilizes magnets as a means for fixing the movable table, it is possible to obtain sufficient fixation holding force and also to be able to accurately perform minute positioning.

In addition, the movable table can be unlocked by pressing the lock bar with your hand, and when you release your hand from the lock bar, the movable table is immediately fixed in that position, making the operation extremely easy.
Moreover, since the operator can feel the locking feeling caused by the permanent magnet and the time between locking and releasing through the lock bar when fixing and releasing the lock, there is no error in operation and there is an advantage that the operability is extremely good.

Claims (1)

[Claims for Utility Model Registration] A movable table 5 movably supported on two parallel guide shafts 9 and 10 and having a reference surface 6 on one side for abutting a fed article; a fixed plate 2 provided below the movable table 5 so as to be positioned along the moving direction of the movable table 5; one end has a magnet 12 that attracts the fixed plate 2; When the lever 14 is pushed down and the magnet 12 is separated from the fixed plate 2, the movable table 5 becomes movable, and when the lever 14 returns, the magnet 12 is moved away from the fixed plate 2.
A guide table device characterized in that a movable table 5 becomes a fixed state when adsorbed to the guide table device.
