Description

[Detailed description of the invention] (Field of industrial application) The invention relates to a label cassette, and more specifically, a label on which a label is pasted on a mount and a bar code etc. is recorded on the label by a printer. A predetermined amount of continuous material is wound around the label cassette, which is removably attached to the pasting machine.Furthermore, printing on the label does not require a dedicated printer, but is printed by other means and wound into a roll. This invention relates to a label cassette into which a rotated label continuous body is attached.

(Prior art) A cassette is a cassette in which a continuous label body, in which a large number of labels with barcodes recorded adjacent to each other are pasted, is wound over a predetermined length around a winding core that is rotatably supported within a housing. Various proposals have been made. These label cassettes are sorted by product inside or outside the store, such as a supermarket, and if necessary, the cassette corresponding to the product is selected and placed in a pasting machine to apply the label to the desired product. It is configured so that it can be done.

In this type of label cassette, for example, as disclosed in Japanese Unexamined Patent Application Publication No. 112786/1986 (portable labeling device), which is an earlier application of the present applicant, a winding core housed in the cassette of the cassette is used. The label continuous body led out from the label cassette is turned and guided along the bottom surface of the label cassette, and the cassette is loaded onto the pasting machine side with the label cassette cut at the rear end.

In a label cassette with such a structure,
The end of the label chain that is guided along the bottom surface of the label cassette is not free and must be held by some means toward the label cassette.

The mechanism that holds the end of the label continuous body is called a mount holding mechanism, and usually includes a mount holder pressed by a spring with a sharp protrusion, and a small holder into which a protrusion at the tip of the mount holder is fitted. It consists of a support plate (receiving plate 21) in which holes are formed,
A label continuous body is guided between the two, and the protrusion of the mount holder is configured to fit into the small hole of the receiving member by penetrating the label continuous body (mounting paper).

Then, the label cassette is attached to the label pasting machine, and when pasting the label, the mount holder is moved up and down so as to move toward and away from the support member by the mechanism on the pasting machine side, and the label continuous body is held in one sheet in the meantime. It is sent out in the amount corresponding to the label.

In conventional label cassettes with such a structure, in order to move the backing paper holder of the label continuous body, which is constantly pressed toward the support plate side by a spring, away from the support plate, it is necessary to move the backing paper holder that is integral with the backing paper holder. , and via protrusions (engaging tongues) protruding from both sides of the label cassette housing.

(Problem to be solved by the invention) In the case of such a structure, when first trying to hold the label continuous body, the above-mentioned protrusion is held from the outside of the label cassette with fingers, and the mount holder is held. It had the disadvantage that it had to be moved up and set, making the operation extremely complicated. That is, it is necessary to maintain the operation of pushing up the mount holder with the fingertip via the protrusion.

(Means for Solving the Problem) The present invention was made to eliminate the above-mentioned conventional drawbacks, and it is designed to link the mount holder that holds the label continuous body (mount) with other members or with manual operation. At the same time, the mount holder is equipped with a lock mechanism that holds the mount holder raised in a predetermined position, and a release mechanism (button) that releases this lock, allowing the mount holder to be easily operated with a single touch. It is configured so that it can be performed in a simplified state.

(Function) A pair of protrusions 9 provided on the label cassette 1
Due to the pushing up action, the mount holder 6 interlocked with this is pushed up against the spring 7, and at the same time, a pair of pins 12 with a spring 11 provided inside the mount holder 6 are pushed up. .
The tip of this pin 12 engages and maintains the recess 16 in which the pair of buttons 15 are arranged.
Therefore, the mount holder 6 is displaced from the state where it is connected to the support plate 14 to the separated state (a gap is formed between the support plate 14 and the tip of the mount holder 6), and the label continuous body (mount) can be easily inserted.

Next, after this insertion is completed, by pressing the button 15 (lock release mechanism), the pin 12 is pushed into the recessed part by the compression action of the spring 11.
Escape from 6. Next, the mount holder 6 is pressed by the action of the spring 7 to a position where its tip is joined to the support plate 14. Therefore, this mount holder 6
The continuous label body (mounting paper) inserted between the support plate 14 and the support plate 14 can be held securely.

(Example) Hereinafter, details of the present invention will be explained based on an example shown in the drawings.

FIG. 1 and the following are illustrations of an embodiment of the present invention, in which a label cassette 1 according to the present invention has a winding core, which is a label holding part on which a continuous label is wound, inside a casing 2 whose upper end is open. 2a,
A label holder 3 formed as a frame having a pair of left and right side plates is rotatably attached to surround this. The bottom plate 4 of the casing 2 is the second
As shown in the figure, the label continuum (mounting paper) 23 is recessed slightly above the left and right side plates of the casing 2, and is unwound from the take-up core 2a. is guided to the rear of the label cassette 1 along.

A support frame 5 is formed at the rear end of the casing 2, and a mount holder 6 is fitted into the support frame 5 so as to be able to rise and fall freely.The mount holder 6 is always pushed downward by a spring 7. being under pressure.

A frame 8 is integrally formed on the mount holder 6 with its position shifted toward the tip of the label cassette 1, and casings 2 are attached to both ends of the frame 8.
A protrusion 9 is formed extending downward along both left and right sides.

Further, as shown in FIG. 3, a through hole 10 is formed horizontally across the substantially central portion of the mount holder 6, and a spring 11 is accommodated within this through hole 10.

Small diameter portions are formed at both ends of the through hole 10, and pins 12 are slidably fitted into the small diameter portions. The inner end of each pin 12 has a head 1 having approximately the same size as the diameter of the through hole 10.
2a, and both ends of the spring 11 are in contact between the heads 12a, giving a force to push each pin 12 outward.

Furthermore, grooves 13a extending in the vertical direction into which the pins 12 can be fitted are formed on both left and right end surfaces of the space 13 in which the mount holder 6 of the support frame 5 moves up and down.

An acute-angled protrusion 6a is formed at the lower end of the mount holder 6, and a support plate 14 with a small hole 14a formed at a position opposite to the protrusion 6a is attached to the left and right side plates of the casing 2 on the lower side of the bottom plate 4. suspended between.

On the other hand, both left and right end surfaces of the support frame 5 are covered with the casing 2.
The rear end portion also serves as a side plate of the casing 2, and a button 15 is slidably fitted into this portion.

The tip of the button 15 passes through the left and right side walls of the support frame 5 and faces into the space 13, and this portion is an enlarged diameter portion 15a to prevent the button 15 from slipping out.

The enlarged diameter portion 15a is slidably fitted into a recess 16 opening into the space 13 of the support frame 5.
The depth of this recessed portion 16 is approximately twice the thickness of the enlarged diameter portion 15a.

Next, the operation of this embodiment configured as above will be explained.

In the normal state, the mount holder 6 is lowered by the pressing force of the spring 7, and the protrusion 6a formed at the lower end thereof is fitted into the through hole 14a of the support plate 14.

Further, the left and right protrusions 9 integral with the mount holder 6 protrude downward beyond the lower end edges of the left and right side plates of the casing 2, as shown in FIG.

In this state, the continuous label body (mounting paper) 23 wound inside the casing 2 is held in the following manner.

That is, the label cassette 1 is normally set in a winding device integrated with a printer, and has a structure in which the continuous label body 23 with barcodes etc. printed thereon is automatically wound around the winding core 2a inside the label cassette 1. is adopted.

FIG. 9 shows an outline of the state in which the winding device is set on the winding device side.

That is, in FIG. 9, the reference numeral 17 is a platen roller that guides the label continuous body 23 sent out from a recording section (not shown), and is guided by a recording head (not shown) arranged adjacent to this platen roller 17. A continuous label body 23 on which a bar code or the like is printed is guided toward the label cassette 1 along a guide 18.

The guide 18 has a support member 19 for the label cassette.
and a set boss 20 of the mount holder 6 are provided.

Further, a support plate 21 made of an elastic member is provided on the board on the side of the winding device, and the support plate 21 is made of an elastic member.
The label cassette 1 is held in a predetermined position in cooperation with the label cassette 1.

In this state, the label continuous body 23 sent out from the platen roller 17 side is automatically wound up into the label cassette 1, and cut by the cutter 22 after being wound up over a predetermined length.

In this way, the continuous label body 23 is wound around the label cassette 1, but at this time, the aforementioned set boss 20 comes into contact with the protrusion 9 of the mount holder 6, as shown in FIG. 5, and compresses the spring 7. The mount holder 6 is being moved upward.

Then, as shown in FIG. 6, the pins 12 protruding from both the left and right sides of the mount holder 6 are moved upward in the groove 13a, climb over the upper end of the groove 13a, and compress the spring 11, thereby compressing the enlarged diameter portion 15a of the button 15.
is fitted into the recess 16 into which it is fitted.

As a result, the button 15 is pushed outward to the maximum extent via the pin 12 by the elastic force of the spring 11.

In this state, since the pin 12 is completely fitted into the recess 16, it does not come out and the mount holder 6 maintains the upwardly moved state.

Therefore, the end of the continuous label body (mounting paper) 23 can be guided between the support plate 14 and the mount holder 6 without being obstructed by the projections 6a.

When the button 15 is pressed with a fingertip while the label continuous body (mounting paper) 23 is set, the pin 12 is pushed out from the recess 16 by compressing the spring 11.
Then, the backing paper holder 6 is lowered by the elastic force of the spring 7, and the protrusion 6a is moved against the label continuous body (mounting paper) 2.
3 and fits into the small hole 14a of the support plate 14.

In this state, the continuous label body (mounting paper) 23 is securely held.

Note that the purpose of upward movement of the mount holder 6 as described above can be achieved by pushing up the protrusion 9 with a fingertip, and is limited to a mechanism that utilizes the set boss 20 shown in FIG. It's not a thing.

The label continuous body 23 is wound in this manner, and the label cassette 1 is mounted on a label pasting machine 70, which will be described later, with its ends (mounting paper) being securely held.

By the way, from the label cassette 1 mounted on the label pasting machine 70 side, the continuous label body 23 must be sent out at a pitch corresponding to the length of the label in accordance with the label pasting operation.

To do this, it is necessary to move the mount holder 6 upward one time at a time to release the label continuous body (mount) 23 from being restrained by the mount holder 6.

In this case, as shown in FIG.
Push up the protrusion 9. Therefore, the support plate 14 and the protrusion 6a are separated, and the label continuous body (mounting paper) 23
is sent out freely.

The moving range of the mount holder 6 pushed up by the push-up plate 130 is the range of the length of the groove 13a, and the pin 12 does not come off the groove 13a as shown in FIG.

As a result, when the pressing operation of the protrusion 9 by the push-up plate 130 is completed and the push-up plate 130 is separated from the protrusion 9, the elastic force of the spring 7 causes the mount holder 6 to
is lowered to hold the label continuous body (mounting paper) 23.

Since this embodiment is constructed as described above, the mount holder 6 is locked in the raised position simply by mounting it on the take-up device side, and the locked state can be released by pressing a button. The holder 6 does not require any complicated operations as in the conventional case, and the continuous label body (mounting paper) 23 can be held and released extremely easily just by a set operation and a push button operation.
