[Detailed Description of the Invention] (Technical Field of the Invention) The present invention has printing heads arranged side by side in order to print on receipt paper for customers and journal paper for storage. The present invention relates to a printing device for a cash register having a configuration in which a stamp mechanism for printing fixed items such as a store name on a receipt paper is disposed corresponding to a printing head section for the receipt paper.

(Technical background of the invention and its problems) Conventionally, in this type of printing device, there is a so-called stamp stand that faces the stamp of the stamp mechanism with the receipt paper in between and serves as a holder for the stamp, and a journal paper. A so-called recording stand, which is a cradle on which a user can write notes, etc., is a structure that is formed separately from sheet metal, etc., and is assembled and fixed with screws, etc. near each print head when the device is assembled. It was becoming.

Therefore, since the number of parts is large and the assembly work is required in a narrow space, there are problems in that the work cannot be carried out efficiently and the manufacturing cost increases.

On the other hand, with today's demand for downsizing of the entire device,
Print heads have also become more compact, and recently, cassette-type printers have been used that allow the ribbon feeding mechanism to be easily replaced, and some are now constructed in the form of a single unit.

However, when the entire print head is removed as a unit for ribbon replacement, maintenance, inspection, etc., with the conventional stamp stand and recording stand mentioned above, the parts are removed from the front side or the paper feed side of each print head. In particular, since it is fixedly located in this upper region, this poses a problem and makes removal work in the upward direction extremely difficult. Therefore, in this case, it is first necessary to completely remove each stamp stand and recording stand from the main body of the apparatus, or to move them laterally to secure space.

For this reason, the time and labor required for this work are large, and it has been desired to reduce the amount of time and labor required.

(Purpose of the invention) The present invention was devised to solve the above-mentioned conventional problems.The purpose of this invention is to reduce the number of parts and assembly man-hours, and to reduce the work required to replace the ribbon or remove the printing head. To provide a printing device for a cash register which can easily and quickly perform the above operations and is highly efficient and economical.

(Summary of the invention) In order to achieve the above object, the present invention basically consists of a first print head for receipt paper and a second print head for journal paper disposed adjacent to the side thereof.
In a cash register printing device, in which a printing head portion of the first printing head portion and a stamp mechanism disposed adjacent to the first printing head portion on the receipt paper delivery side are attached to the device main body, the base end portion is rotated to the device main body. a rotating frame member that is movably supported and that moves between an operating position corresponding to the first and second print head portions and an open position that is moved above the operating position as the frame member rotates; a holding means for holding the rotating frame member in the operating position, and in the operating position, a first surface constituting a stamp pad that is close to the first print head and faces the stamp mechanism; The present invention proposes a printing device for a cash register, characterized in that a second surface constituting a recording stand adjacent to a second printing head portion is integrally formed with the rotating frame member.

According to the above configuration, when the rotating frame member is placed in the operating position, the first and second surfaces are simultaneously set at predetermined positions and act as a stamp stand and a recording stand,
In addition, when replacing the ribbon or removing the print head, by rotating the rotating frame member toward the open position, the peripheral area of each print head, especially the upper area, is opened, making the work easier. This fully achieves the above objectives.

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

It has a support plate 21 which is attached with screws 20 to the support plate 21. A printing surface on which fixed items such as a store name are engraved is formed on the upper surface of the stamp, and is positioned opposite to the paper feed port 14.

Reference numeral 22 denotes a rotating frame member, which is rotatably supported by pillars 23 on both sides of the base end 22a, and whose free edge extends forward and connects the first and second print heads 11, 12. It has a width that covers the entire area.

In FIG. 1 only one of the struts 23 is visible, while the other strut 23 is shown in FIG.
Both of these pillars are also integrally erected on the bottom plate portion of the device main body 10 and constitute a part of the main body 10.

The rotating frame member 22 is connected to these supports 2 by a pin-shaped support shaft 25 protruding from the base end via a spacer 24.
3, and is configured to rotate around an axis X--X that is rearward of the first and second print heads 11 and 12 and parallel and horizontal thereto.

The upper end of the pillar 23 shown in FIG. 1 has a bifurcated shape, and the upper end of the other pillar 23 shown in FIG. 2 has the form of a support hole into which the support shaft 25 is inserted. Therefore,
The rotating frame member 22 can be inserted into the main body 10 by first inserting one support shaft 25 into the support hole, and then engaging the other support shaft 25 with the bifurcated portion. It can be installed with one touch and does not require any installation screws.

A toggle spring 26 is suspended between both columns 23 and the rotating frame member 22, and the biasing direction of the spring 26 changes with the support shaft 25 as the dead center.

The pivot frame member 22 is pivotable from an operating position shown in solid lines in FIGS. 1 and 2 to an open position shown in chain lines in the direction of the arrow in FIG. It works in the direction of holding. The open position is regulated by contact with an abutment support 27 that is integrally provided on the bottom plate portion of the main body 10 .

On the free edge of the rotating frame member 22, a first surface 30 is provided at a portion corresponding to the first print head portion 11 and the stamp mechanism 17, and a first surface 30 is provided at a portion corresponding to the second print head portion 12. The two surfaces 31 are integrally formed. In the operating position, the first surface 30 faces the stamp 18 of the stamp mechanism 17 with the receipt paper R in between, and constitutes a so-called stamp stand. On the other hand, the second surface 31 is formed by extending its free edge downward and its lower end is close to the upper side of the paper feed port 14 of the second print head section 12. It constitutes a so-called recording stand on which the user can write notes or other desired information on the journal paper J sent out to the upper side.

A recess 32 formed on the opposite side of the first surface 30, that is, on the upper surface side in FIG.
A cutting blade 33 for cutting the receipt paper R is fixed, and the blade portion protrudes forward and faces the path of the paper R.

Furthermore, on both sides of the first surface 30, a pair of hook-shaped engagement receiving portions 34a and 34b are integrally bent at the free end edges of the rotating frame member 22.
This rotating frame member 22 has first and second surfaces 30,
31. The entire body including the engagement receiving portions 34a and 34b can be integrally molded from synthetic resin. In this case, reinforcing ribs are simultaneously molded on both sides and the back surface of the member 22 to ensure sufficient strength of the frame structure.

Note that each part, for example, the first and second surfaces 3
It is also possible to form the parts 0 and 31 from a metal plate or the like separately from the main body part of the member 22, and to fix this integrally to the main body part of the member 22.

The printing device shown in FIG. 1, as shown by the chain line,
It is covered by the attached top cover 35, but the cover 35 itself has a conventional configuration, and is detachably attached to the lower case (not shown) from above, and is configured so that it cannot be easily removed in the illustrated attachment position. ing. Note that openings are formed in the cover 35 to correspond to the respective paper feed ports 14 of the first and second print head sections 11 and 12, but they are not shown.

As shown in FIG. 2, when the rotating frame member 22 is in the operating position indicated by the solid line, a ring is connected to the rear edge of the first surface 30 and is formed on the back surface of the member 22 at approximately right angles to the surface 30. The contact surface 36 is connected to the first print head 1
1, that is, the front surface of the ribbon cassette 13. By this,
The first print head portion 11 is pressed and held toward the insertion position. The spring 26 also assists in this with its biasing force.

On the back surface of the top cover 35, there are engaging pieces 37a, 37 corresponding to the engaging receiving parts 34a, 34b.
b is provided protrudingly. The respective engaging pieces and the engaging receiving portion constitute a holding means, and their mutual engagement serves to hold the rotating frame member 22 in the operating position.
Note that one of the engagement pieces 37a is also shown in FIG. The other 37b also has a similar shape.

During printing, the stamp 18 of the stamp mechanism 17 comes into contact with the first surface 30 constituting the stamp pad from below as shown by the chain line in FIG. Therefore, there is no risk that the member 22 will be displaced or pushed up from the operating position due to impact during printing. In this way, by using the top cover, a special member for holding can be omitted.

Note that the receipt paper R is pulled out from a roll (not shown) disposed at the rear of the device main body 10, inserted into the first printing head section 11 from its upper end, predetermined printing is performed therein, and then sent out. It is sent out to the side, passes between the stamp 18 and the first surface 30, and is guided to the outside of the cover 35.

A locking piece 38 is further integrally provided on the abutting surface 36, and as shown in FIG. 36 to more effectively press the head portion 11 in the insertion direction.

As can be seen in FIG. 7, the locking pieces 38 are provided in a pair at spaced apart positions, and hold the print head 11 uniformly without tilting from side to side.

When replacing the ribbon cassette 13 or removing the entire first printing head section 11, it is sufficient to move the rotating frame member 22 upward toward the open position with the top cover 35 removed. As a result, the periphery of the first printing head section 11, especially the area above it, is completely opened, making it possible to perform the above-mentioned removal operation easily and quickly.

On the other hand, as for the second print head section 12, in the operating position, as shown by the solid line in FIG. The printing head 12 is pressed against the front side of the ribbon cassette 13, so that the printing head 12 is pressed and held at the insertion position.

Similarly, after removing the top cover 35, if the rotating frame member 22 is moved upward in the direction of the arrow as shown by the chain line toward the open position, the upper area of the second print head 12 is opened. This makes it possible to easily and quickly remove the head section 12.

Furthermore, since the rotating frame member 22 is configured to rotate around the axis X-X, it does not take up much space.
The configuration is simple and positional accuracy is easy to achieve.

Note that the journal paper J is pulled out from a roll (not shown) disposed at the rear of the apparatus main body 10, introduced into the second print head section 12 from its upper end, and after predetermined printing is performed therein. It is sent out from the sending side, passes through the second surface 31 that forms the recording stand, and is again wound up and stored at the rear of the apparatus main body.

In FIGS. 4 and 5, the configuration for removably supporting the printing head section on the supports 15 and 16 is shown in the second section.
Taking the print head section 12 as an example, the head section 12 has a metal mounting plate 39 fixed to its back surface. At the lower corner of the head portion 12, as shown in FIG.
A pair of ears 40b are formed integrally with the mounting plate 39 on both sides of the support column 16, and these are engaged with an engagement groove 41 formed in an inclined manner at the upper end of the support column 16 along the inclined vertical direction shown by the arrow. It is structured as follows.
Then, in the engaged state, the pair of ears 40b
The upper end surface 42 hits the lower end surface of the head portion 12, as can be seen in FIG. 3, and a stable mounting position is thereby determined.

On the other hand, as shown in FIG. 5, a mounting hole 43 is formed in the mounting plate 39 at the upper corner of the head portion 12, and the mounting hole 43 is inserted into the positioning pin 45 projecting from the upper end inclined surface 44 of the support column 15. This part is attached by engaging the inclined surface 44 at a substantially right angle as shown in FIG.

When installing the printing bed section 12, first the lower part of the head section 12 is mounted on the support column 16 along the vertical direction, and then the upper end section of the head section 12 is tilted backward. The upper end is the pillar 15
The device is automatically attached to the device, making attachment and detachment extremely easy. That is, this configuration allows one-touch attachment and detachment without using any fixing means such as attachment screws.

The configuration shown in FIGS. 4 and 5 is exactly the same for the first print head section 11, so the explanation will be omitted.

In the embodiments of the present invention described above, a unit-shaped printing head section equipped with a ribbon cassette is disclosed, but the present invention can be applied to structures having other ordinary ribbon mechanisms.

In addition, the present invention is not limited to the embodiments.

(Effects of the invention) As described above, according to the invention, a rotating frame member is provided, and the first and second surfaces constituting the stamp stand and the recording stand, respectively, are integrally formed on the rotating frame member.
