Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a printer that has independent printing systems for printing on two types of printing media, such as bankbooks and journal paper.

[Conventional technology]

A printer having both bankbook printing and journal printing functions will be explained using the side view of FIG. 5.

Printers that have both of the above functions are easy to use,
For reasons such as improving processing speed, there are two systems of printing sections as shown in the figure, and the journal printing section 1 is placed on the upper side because visibility of printed characters is required.
The passbook printing section 2 is arranged and integrated at the bottom to improve operability by horizontally inserting the printing medium.

In the figure, reference numeral 3 denotes a journal conveying section, in which journal paper 4 is conveyed via a platen 5. Further, this journal conveying section 3 rotates about a rotational fulcrum 6 to open a part of the journal printing section 1 and opening the bankbook printing section 2.

7 is a printing head of the journal printing section 1, 8 is an ink ribbon, and 9 is an ink ribbon cassette.

Next, 10 is the print head of the passbook printing section 2;
is an ink ribbon, 12 is an ink ribbon cassette,
13 is a platen.

In such a printer, replacing the ribbon cassette 10 of the bankbook printing section 2 is performed by opening the journal printing section 1, but it is necessary to prevent the rigidity of the entire printer from decreasing and to reduce the weight of the journal printing section 1 that opens and closes. In consideration of this point, as mentioned above, only a part of the journal printing section 1, not the entire journal conveying section 3, is opened and closed.

[Problem that the invention attempts to solve]

However, with the above configuration, there is a problem in that when the journal conveying section is rotated, the tip of the print head and its surrounding parts may interfere with each other and be damaged.

[Means for solving the problem]

This invention has two parts: journal printing part and passbook printing part.
In a passbook/journal printer, the journal printing part is located above the passbook printing part, and the passbook printing part is opened by rotating and opening the journal conveying part. a retracting means for retracting a print head mounted on a carriage by moving it in a direction parallel to the platen of the carriage; a rotation locking means for a journal conveying section that is linked to the movement of the carriage on which the print head is mounted; and a retracting means for the carriage. The present invention is characterized by comprising means for fixing the carriage in conjunction with the movement of the journal transport section at the position.

[Effect]

According to the above configuration, when the journal printing section is ready for printing, that is, when the journal conveyance section is closed, the rotation locking means of the journal conveyance section acts to keep the journal conveyance section in a fixed state and the printing head is movable. You can print by

Next, when opening the journal transport section to release the passbook printing section in order to replace the ribbon cassette in the passbook printing section, first move the carriage along the platen and then move the print head using the retracting means. It is possible to move the journal backward from the platen, release the rotation locking means of the journal conveyance section as the carriage moves, and raise the journal conveyance section so that the journal conveyance section can rotate without interference from the printing head. can.

When the journal transport is raised, the carriage becomes fixed in its retracted position by the action of the carriage fixing means, and this state remains until the journal transport is returned to its closed position, so that the journal transport does not stop. There is no interference from the print head when returning the print head. Therefore, the print head is retracted and remains fixed whenever the journal transport section is opened or closed, and the print head and its surrounding parts are not damaged when the journal transport section is opened or closed.

Reference numeral 21 denotes a plate cam provided along the guide 15, which is adapted to engage and slide with a portion of the print head mount 17, and is adapted to slide on the print head mount as the carriage 14 moves in the X direction. 17
is moved in the Y direction following the plate cam 21, thereby moving the carriage 14.

FIG. 2 is a plan view showing the Y-direction position of the print head 7 at each position due to the movement of the carriage 14 in the X-direction, and the Y-direction position is constant in the range from X-direction position () to (). However, the print head 7 moves along the plate cam 21 in the Y direction while moving from position ( ) in the X direction to position ( ). Therefore, when rotating the journal conveying section 3, interference of the print head 7 occurs in the range from position () to () in the X direction, but since the print head 7 retreats from the platen 5 in position (). Therefore, the rotation of the journal conveying section 3 is not interfered with, and the journal conveying section 3 can be rotated without damaging the printing head 7.

Next, the fixing structure of the journal conveyance section 3 will be explained using the perspective view of FIG. Reference numeral 3 denotes a journal conveying section, which is adapted to rotate in the direction of the arrow about a rotation fulcrum 6, and has a locking protrusion 22 protruding from its side wall.

15 is a guide, and 14 is a carriage.

Reference numeral 23 designates a lever, which has a locking pawl 24 on one side and a locking end 26 on the other side via a rotation fulcrum 25.

27 is a long hole 28 and a pin 29 that can be moved in the X direction.
It is a plate supported by the lever 23, and has a passive piece 30 at one end with which the carriage 14 comes into contact, and a locking part 31 that stops the rotation of the lever 23 at the other end. 32 is a spring that draws the plate 27 toward the locking portion 31 side.

According to the above configuration, when the printer is in operation, the locking pawl 24 of the lever 23 is attached to the locking protrusion 24 as shown in the figure.
It is in a locked state.

Therefore, when rotating the journal conveyance section 3 to replace the ribbon cassette of the passbook printing section 2, the carriage 14 is moved in the direction of the arrow in the The locking portion 31 is removed from the locking end 26 of the lever 23 by moving in the direction of the arrow against the force of the spring 32. As a result, the upper end of the lever 23 can be pushed and rotated, the locking pawl 24 is released from the locking protrusion 22, and the journal conveying section 3 is rotated in the direction of the arrow by the rotation fulcrum 6. be able to.

Next, using the side view of FIG.
We will explain the structure of fixing with position().

In the figure, reference numeral 3 denotes a journal conveying section, 7 a journal print head, and 14 a carriage on which the journal print head 7 is mounted and moves along a guide 15. A groove 33 is formed in a part of the carriage.

Reference numeral 34 denotes a fixing member, which is rotatably supported by a rotational fulcrum 35. A fixing protrusion 36 is protruded from the fixing member 34, and one end of the fixing member 34 comes into contact with the journal conveying section 3. Contact end 37
The other end is a lever-like end and is pulled by a spring 38 so that the fixing protrusion 36 fits into the groove 33.

According to this configuration, the illustrated journal conveyance section 3
When the journal is rotating and rising, the journal conveying section 3 is not in contact with and pressing against the abutting end 37 of the fixing member 34, so the fixing protrusion 36 of the fixing member 34 is moved by the force of the spring 38. 1
4, the carriage 14 is prevented from moving in the arrow direction, that is, in the X direction, and is fixed in position ( ).

When the journal conveying section 3 is closed, the journal conveying section 3 presses the abutting end 37 of the fixing member 34, and the fixing protrusion 36 comes out of the groove 33 as shown by the chain line, and the carriage 14 moves in the direction of the arrow. It becomes possible to do so.

The effects of each of the above configurations will be explained below in conjunction with each other.

When the journal printing section 3 is in a printable state, that is, when the journal conveyance section 3 is closed, the journal conveyance section 3 is in a fixed state with the locking pawl 24 of the lever 23 locked on the locking protrusion 22, and the printing head is 7
is in the range from position () to position () in FIG.

In this state, the locking end 26 of the lever 23 is locked to the locking portion 31 of the plate 27, so the locking claw 24 cannot be removed from the locking protrusion 22 by rotating the lever 23, and the journal is locked. The fixed state of the transport section 3 cannot be released.

Further, since the journal conveying section 3 is lowered, the abutting end 37 of the fixing member 34 is pushed, and the fixing protrusion 36 is disengaged from the groove 33 of the carriage 14, so that the carriage 14 is movable in the X direction. Printing operations can be performed.

Next, when rotating the journal transport section 3 upward to open the passbook printing section 2 in order to replace the ribbon cassette of the passbook printing section 2, etc., first move the carriage 14 to position (). Thus, the print head 7 is moved back from the platen 5 by a certain distance.

While moving this carriage 14 to the position (), the carriage 14 moves to the passive piece 3 of the plate 27.
Press 0 and move lever 23 by position ().
The locking portion 31 of the plate 27 is disengaged from the locking end 26 of the plate 27, and the lever 23 is unlocked. As a result, in the position (), the print head 7 is moved back from the platen 5 by a certain distance, and the lever 2
3 becomes rotatable, and the fixed state of the journal conveyance section 3 is released to enable rotation.

Therefore, when the journal conveying section 3 is rotated around the rotation fulcrum 6 to open the bankbook printing section 2, the rotation operation can be performed without interfering with the printing head 7, etc., and the inside of the opened bankbook printing section 2 can be rotated. The ribbon cassette 10 can be replaced. In this state, since the journal conveying section 3 is up, the fixing protrusion 36 of the fixing member 34 is attached to the groove 33 of the carriage 14 which is in position ().
The carriage 14 is fixed and cannot be moved.

[Effect of idea]

According to the present invention described in detail above, in a passbook/journal printer in which the journal transport section of the journal printing section located above the passbook printing section can be opened and closed, the printing information mounted on the carriage of the journal printing section is provided. Retraction means for retracting the head by moving the print head in a direction parallel to the platen of the cartridge; rotation locking means for a journal conveyance unit that is linked to the movement of the carriage on which the print head is mounted; and journal conveyance at the retraction position of the carriage. By providing a means for fixing the carriage that moves in conjunction with the movement of the journal, the journal transport section cannot be rotated when journal printing is possible, and only interferes with the print head when the journal print head retreats from the platen. Now you can open the bankbook printing section by rotating the journal conveyance section without having to do anything, and when the journal conveyance section is up, the carriage is fixed and the journal conveyance section returns to its original position. Since it can be moved from the front, there is no interference with the print head when it is closed, and there is no chance of damage to the print head or its surroundings when opening or closing the bankbook printing section to replace the ribbon cassette. This means that it can be eliminated.
