Abstract

PURPOSE:To prevent a medium from being caught in a notch on a side plate by forming the contact face of a width control lever on the notch of the side plate of a width control part on the same face as the side plate. CONSTITUTION:When a medium 1 is inserted into an insertion port 2, a control part transfers the medium 1 to a width control part by a medium moving means. Since the width of a traveling route is wider than the width of the medium 1, the medium 1 is located on an optional position in the traveling line, and when width control operation is not executed, the width control lever 11 is receded to a position to be almost the same face as the inside face of the side plate 3a as shown in an alternate long and two short dashes line so as not to interrupt the traveling of the medium. In the above state, the control part resets the medium moving means, drives a solenoid 9 and moves the lever 11 in an arrow direction and the lever 11 linearly moves and moves the medium 1 on an optional position in the traveling route close to the medium traveling reference face side as shown by a solid line to complete the width control operation.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a width alignment mechanism for media such as passbooks and slips in passbook recording machines.

[Prior Art] In passbook bookkeeping machines at financial institutions, when reading and writing magnetic stripes on media and printing transaction details, it is necessary to check the position of the magnetic head and the printing position relative to the magnetic stripe on the media. The medium is moved toward a predetermined traveling reference surface of the medium so that the distance between the two sides is always constant in the width direction of the medium. This operation is called width shifting, and the width shifting mechanism will be explained below with reference to the drawings.

Fig. 4 is a plan view, Fig. 5 is a front view, Fig. 6 is a plan view of the notch, and Fig. 7 is an enlarged perspective view of the notch. is an insertion slot for inserting this medium 1 into the passbook entry machine, 3a and 3b are side plates, 4 is an upper guide, and 5 is a lower guide, which form a running path for the medium 1, and the above-mentioned The insertion port 2 is fixed to the end of this travel path so as to smoothly guide the medium, and the inner surface of one of the side plates, in this embodiment the side plate 3b, serves as a medium travel reference surface.

Reference numeral 6 denotes a width adjustment lever, which is provided at the width adjustment portion on the side plate 3a side opposite to the medium running reference surface, and is connected to the solenoid 9 via a link 8 that is rotatably and loosely supported on a fulcrum 7. It is connected.

In the side play 1-3a, upper guide 4, and lower guide 5 of the width adjustment part where the width adjustment lever 6 is installed, there are notches 10 as shown in FIGS. 6 and 7 so as not to interfere with the width adjustment lever 6. is formed.

In addition, it has a medium detection means and a medium transport means (not shown), and the medium 1 runs on the lower guide 5 surface along the medium running reference plane. The transfer means and the solenoid 9 are controlled by a control section (not shown).

The width adjustment operation of the medium with the above configuration will be explained below.

When the medium 1 is inserted into the insertion port 2, the control section detects this using the medium detection means, and transfers the medium to the width adjusting section using the medium transfer means.

At this time, since the width of the running path is wider than the width of the medium 1, the medium 1 is located at an arbitrary position within the running path, and
When the width adjustment lever 6 is not performing the width adjustment operation, that is, when the solenoid 9 is not attracted, it is located at a position away from the notch 10, as shown by the two-dot chain line in FIG. 5, so as not to interfere with the movement of the medium. It has become.

In this state, after releasing the medium transfer means, the control section activates the solenoid 9 to move the width adjustment lever 6 in the direction of the arrow, and the medium 1 located at an arbitrary position within the travel path is shown by a solid line in FIG. The width shifting operation is completed when the medium is moved toward the medium running reference plane side.

[Problems to be Solved by the Invention] However, according to the width shifting mechanism as described above, the side plate, upper guide, and lower guide of the width shifting section where the width shifting lever is installed are provided with a mechanism to prevent interference with the width shifting lever. There is a notch in the top. Therefore, when the medium is transferred to the width-adjusting position, the medium may get caught in this notch, resulting in a jam state in which the medium cannot be moved.

Therefore, as shown in Figures 6 and 7, the shape of the notches in the upper and lower guides is such that both ends are sloped to reduce the load when the medium travels. Not much effect can be expected if the hair is curly or curly.

When the medium is transferred to the width shifting position, it may become stuck and the width shifting cannot be performed.

Another problem is that when the medium is fed diagonally, it gets caught in the notch of the side plate and becomes jammed, making it impossible to adjust the width.

[Means for Solving the Problems] Therefore, the present invention provides a medium running path for passbooks, slips, etc. formed by an upper guide and a lower guide supported by the side plates, with one side plate being used as a medium running reference plane. Then, a width adjustment lever is arranged on the side plate side facing the medium travel reference surface at a predetermined location on this travel path to form a width adjustment portion, and the transported medium is pressed by the width adjustment lever so that it hits the media travel reference surface. In the media width shifting mechanism, the width shifting lever cuts out the side plate of the opposing width shifting section, and also forms recesses in the opposing end surfaces of the upper guide and the lower guide to smooth the edges in the running direction. Normally, the width adjustment lever waits at a position where the contact surface is almost flush with the inner surface of the side plate, and during width adjustment, the width adjustment lever is inserted linearly along the recess to face the media. It is characterized in that it is pressed perpendicularly to the medium running reference surface.

[Function] According to the above configuration, even if the running medium is bent or bent, it will not be caught by the guides vertically or vertically when the moving medium is moved by the centering lever, and moreover, the medium will not travel obliquely along the running path. Even if media is fed, the contact surface of the width adjustment lever is on the same surface as the side plate in the notch of the side plate in the width adjustment section, so the media will not get caught in the side plate notch, preventing jamming. .

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

In the following description, parts similar to those in the above-mentioned prior art will be described using the same reference numerals.

Fig. 1 is a plan view, Fig. 2 is a front view, and Fig. 3 is a perspective view of the recess. , 3a and 3b are the side play], 4 is the upper guide, and 5
is a lower guide, which forms a running path for the medium 1, and the insertion port 2 is fixed to the end of this running path so as to smoothly guide the medium;
In this embodiment, the inner surface of the side plate 3b serves as a medium traveling reference surface.

Reference numeral 11 denotes a width shifting lever, which is provided at the width shifting portion on the side plate 3a side opposite to the medium running reference surface, and is connected to the solenoid 9 via a link 8 rotatably supported by a fulcrum 7. It is connected.

The width adjustment lever 1 is placed on the opposite side of the upper guide 4 and lower guide 5 of the width adjustment part where the width adjustment lever 11 is installed.
A recess 12 is formed so as not to interfere with the recess 1 .

As shown in FIG. 3, the concave portion 12 has a smooth curved or sloped shape so that the end portion in the running direction is gradually concave to prevent the medium 1 from getting caught.

In addition, a notch (not shown) is provided in the side plate 3a to prevent the width adjustment lever 11 from coming into contact with this recess 12, and the width adjustment lever 11 normally has a contact surface force at its tip end facing the inner surface of the side plate 3a. It waits at a position substantially flush with the side plate 3a so that it does not interfere with the running of the medium 1, and the running medium acts as a guide in the recess 12 in the same way as the side plate 3a.

In addition, it has a medium detection means and a medium transport means (not shown), and the medium 1 runs on the lower guide 5 surface along the medium running reference plane. The transfer means and the solenoid 9 are controlled by a control section (not shown).

The medium width adjusting operation with the above configuration will be explained below.

When the medium 1 is inserted into the insertion port 2, the control section detects this using the medium detection means, and transfers the medium to the width adjusting section using the medium transfer means.

At this time, since the width of the running path is wider than the width of the medium 1, the medium 1 is located at an arbitrary position within the running path, and
When the width adjustment lever 11 is not performing the width adjustment operation, that is, when the solenoid 9 is not attracted, the width adjustment lever 11 is at a position where the contact surface is almost flush with the inner surface of the side plate 3a, as shown by the two-dot chain line in FIG. The moving medium 1 is located at a position where the four parts 12 function as a running guide in the same way as the side plate 3a.

In this state, the control unit releases the medium transfer means, and then operates the solenoid 9 to move the width adjustment lever 11 in the direction of the arrow. At this time, the recess 12 serves as a guide for the width adjustment lever 11, and the width adjustment lever 11 is moved in a straight line. The medium 1, which has been moved in a circular motion and is located at an arbitrary position within the travel path, is moved toward the medium travel reference plane side as shown by the solid line in FIG. 1, and the width adjustment operation is completed.

〔Effect of the invention〕

According to the present invention described in detail above, in the medium running path for passbooks, tickets, etc. formed by the upper guide and lower guide supported by the side plates, one of the side plates is used as the medium running reference plane, and this running path is formed by the upper guide and the lower guide supported by the side plates. A shifting lever is arranged on the side plate side facing the media running reference surface at a predetermined location on the path to form a width shifting section, and the media width is determined by pressing the transported medium with the width shifting lever to make it come into contact with the media running reference surface. In the shifting mechanism, the side plate of the shifting section facing the shifting lever is cut out, and recesses are formed in the opposing end surfaces of the upper guide and the lower guide, respectively, so that the edges in the running direction have a smooth shape. Sometimes, the width shifting lever waits at a position where the contact surface is almost flush with the inner surface of the side plate, and during width shifting, the width shifting lever is inserted linearly along the recess to create a media running reference surface that faces the medium. By pressing the media at right angles to the media, even if the traveling medium is bent or bent, it will not get caught in the vertical guide when shifting using the width shifting lever, which has the effect of preventing the occurrence of jams.

In addition, even if the media is sent diagonally along the travel path, the media will get caught in the notch of the side plate because the notch of the side plate of the width shifting part has the contact surface of the width shifting lever on the same surface as the side plate. This also has the effect of preventing jams from occurring.

Furthermore, the width adjustment lever is guided by the recess and enters the recess, resulting in accurate linear movement, which allows the medium to be pressed at an angle perpendicular to the media travel reference plane, thereby ensuring correct width adjustment. It has the effect of

The above has the effect of enabling stable work with less jamming when transferring the medium to the width-aligning position.
