Abstract

PURPOSE:To enable a monocolor printer to be remodeled into a multicolor printer, by equipping the monocolor printer with a driving part for color selection. CONSTITUTION:Fitting of a color-selecting motor unit 19 for remodeling a monocolor printer into a multicolor printer can be completed simply by pushing in the unit 19 from the upper side of a carriage 11. With the motor 19 rotated in the direction of an arrow F, an oscillatable lever 14 integral with an intermediate gear 13 is turned in the direction of an arrow B with a fulcrum 29 as a center, since a gear 20 is in mesh with a tooth part 30 of the intermediate gear 13. Since an arm 16 provided on a cartridge holder 15 is engaged with an engaging part 28 of the lever 14, the cartridge holder 15 is turned in the direction of an arrow C with a projection 26 as a center, whereby a color band of an ink ribbon is shifted, and the holder 15 is stopped at such a position that an arbitrary color band is opposed to a printing head. With the motor 19 rotated in the direction of an arrow G, the cartridge holder 15 is turned in the direction of an arrow E with projections 26, 27 as a center. Accordingly, the cartridge holder can be turned by forward and reverse rotations of the motor 19.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer capable of printing in multiple colors (hereinafter referred to as a multicolor printer).

[Conventional technology]

An example of a conventional multicolor printer is shown in FIG. If this method is followed, the motor 1 for color selection will be the paper industry 17'.
The motor 1 is installed at the bottom of the cam 2. is transmitted to the swing lever 6, and the ribbon cartridge 5
The color selection was performed by moving the cartridge holder 4 mounted with the color up and down.

[Problem that the invention seeks to solve]

According to this structure, the motor 1 is installed at the bottom of the paper industry 8.
My friend, compared to monochrome printers (hereinafter referred to as monocolor printers), the external dimensions do not need to be large, but on the other hand, it is not possible to convert a seven-color printer to a multicolor printer, and it is difficult to print in multiple colors. If the lines intersect, f
RFC has a problem in that it requires the purchase of a multicolor printer and imposes high noise burden on the user.

The present invention solves the above problems, and its purpose is to enable the user to freely and easily convert a monochrome printer into a multi-color printer at any time.
An e-printer? It is about providing.

[Means for solving problems]

The printer according to the present invention has a structure that allows it to be converted into a multi-color printer by attaching a purple power section for color selection to a mono-color printer. Features.

〔Example〕

An embodiment according to the invention is, of course, shown in FIGS. 1 and 2.

The structure will be explained with reference to FIG. 1. A print head 12 is fixed to a carriage 11, and an intermediate gear 13 and a swing lever 14 are each pivotally supported while meshing with each other.

On the other hand, a cartridge holder 15 to which a ribbon cartridge 18 can be freely attached and detached is attached to walls 23 on both sides of the carriage 11.
．． The arm 16 of the cartridge holder 15 engages with the engaging portion 28 of the swing lever 14 .

Further, the carriage 11 is provided with fixing claws 21 and 22 of the color selection motor unit 19, and a connector 25 for electrically connecting the electric recess and the motor unit 19. From above the carriage 11, arrow A is attached to the mounting bracket of the motor unit 19 for remodeling into a multi-color printer.
This is completed by pushing the motor unit 19 in the direction of.

At this time, the tooth X2o protruding from the motor unit 19
is engaged with the teeth 30 of the intermediate gear 13 and the motor unit 19
At the same time, the motor unit 19 and the connector 25 are connected to each other and connected to the electric circuit. Motor unit 19 is 751 foot CD position t1t-! When you push it in, it will lock into place with the claws 21 and 22.

Next, the color switching operation of the ink ribbon 17 will be explained.

When the motor 19 rotates in the direction of the arrow 20,000, the gear 2° meshes with the teeth 3o of the intermediate gear 13, so the swinging lever 14, which is integrated with the intermediate gear 15, moves in the direction of the arrow B around the fulcrum 29.
rotated in the direction. Then.

Arm 1 equipped with cartridge holder 15VC
6 is engaged with the engaging portion 28 of the swing lever, the cartridge holder 15 is rotated in the direction of arrow C around the entire center of the protrusions 26 and 27, and the color band of the ink ribbon 17 changes.
It opposes the print head 12 and stops at an arbitrary color band. Then, the rotation of 19 is also stopped. When the print head 12 is driven, any color is printed on the recording paper. Further, when the motor 19 is completely rotated in the direction of the arrow G, the swinging lever 14 is swung in the direction of the arrow with the fulcrum 29 being the center. Along with this, the cartridge holder 15 is rotated in the direction of arrow E about the projections 26 and 27i. At this time, the cartridge holder is rotated in the opposite direction when the motor 19 rotates in the direction of arrow F.

As described above, in order to change the color of the ink ribbon for the actual ink ribbon, depending on the forward and reverse rotation of the motor, the swing lever 14i should be swung in the direction of arrow B or arrow C, and the cartridge holder should be moved in the direction of arrow C or Possible by rotating in the direction of arrow E
becomes.

〔Effect of the invention〕

As described above, according to the present invention, the motor unit can be mounted simply by pushing it in, and can be easily mounted on the vertebrae at any time without any tools. Furthermore, since the motor unit is mounted on the carriage, there is no need to increase the external dimensions compared to monochrome printers, making it possible to provide a compact multicolor printer. Furthermore, by completely modifying a monochrome printer, it can be made into a multicolor printer, which has the effect of greatly reducing the economic burden on the user.
